3385 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
3387 Enabled VPATH feature: changed nearly all Makefiles (149 files).
3388 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
3390 One basic decision: e.g. src/clean.mk includes further files. In order
3391 to make this work there are two solutions:
3392 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
3393 run configure on them. This way they can use
3394 'include $(srcdir)/port-clean.mk'
3395 - always include clean.mk by the Makefile at the same level. To avoid
3396 that `make clean` tries to include and build Makefile.dep the
3397 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
3398 implemented, because now even `make uninstall` doesn't create
3399 Makefile.in. clean.mk could be eliminated by pasting it in
3402 * debugger/mcs51/Makefile.in: build own objects from library sources
3403 (SLIB, SDCC) in current directory
3405 * configure, configure.in: renamed --disable-device-lib-build in
3406 --disable-device-lib; added --enable-doc, the required tools are
3407 searched by configure; added result message; the toolchain for the
3408 belonging ports are now only built, if the port is enabled.
3410 * support/regression/*: all output is written in directory gen, because
3411 the fwk and ports directories don't livet in the build tree using vpath
3413 * doc/sdccman.lyx: renamed --disable-device-lib-build to
3414 --disable-device-lib, added --enable-doc, added section VPATH
3416 * sim/ucsim/configure.in,
3417 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
3418 z80 are enabled by default
3420 2006-04-24 Raphael Neider <rneider AT web.de>
3422 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
3423 to config word, "pic14_"-prefixed some extern functions
3424 (pic14_emitConfigWord): emit __config directive(s) if assignment to
3425 config word has been found
3426 * src/pic/device.h: added prototypes
3427 * src/pic/pcode.c: added "pic14_"-prefix where needed
3428 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
3430 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
3432 (pic14emitRegularMap): ignore config words,
3433 (pic14createInterruptVect): moved generating __config directives away
3434 (picglue): have __config directives emitted
3436 2006-04-24 Borut Razem <borut.razem AT siol.net>

3443 registers that have not been assigned proper liveranges,
3444 fixes #1469504 and #1474602,
3445 (pCodeRegOptimizeRegUsage): fixed typo in comment
3447 2006-04-24 Borut Razem <borut.razem AT siol.net>
3449 * device/examples/main8051.c: deleted - it was removed from CVS
3450 24.mar.2000 and after that modified 18.feb.2001, so it reappered
3451 after the transition to Subversion
3452 * src/SDCCalloc.h: deleted - it was removed from CVS
3453 3.feb.2001 and after that modified 18.feb.2001, so it reappered

3691 implemented patch 1120823 Thanks to Willy De la Court (normal
3692 interrupts need an interrupt number now if they are made critical),
3693 and enabled nesting of critical functions though not for gbz80
3694 (genCritical, genEndCritical): added functions
3695 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
3696 * src/z80/mappings.i: added "ei" to all mappings

3708 the left operand is shorter than the result (c* = lit-c* + int),
3710 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
3713 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3715 * src/.version: increased version number to 2.5.5
3716 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
3717 linking is done manually in pic16 port's _linkEdit,
3718 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
3719 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
3720 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
3721 allocate asmop as AOP_ACC,
3722 (aopForRemat): added parameter 'bool result' in function declaration,
3723 (pic16_aopGet): return AOP_ACC when accessing WREG,
3724 (pic16_popGetTempReg): minor modification,

3735 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
3736 call to allocReg, not by manually allocating a new one,
3737 (pic16_assignRegisters): now before going through the register
3738 allocating functions mark all registers as free. This eliminates some
3739 side effects resulting from peephole parser done earlier in the backbone
3741 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

3799 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
3800 which dumps before the function entry point a data byte which represents
3801 the number of the local variables used by the specified function, added
3802 'xinst' for initial support for Extended Instruction Support,
3803 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
3804 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
3805 port->fun_prefix anymore (may change later),
3806 (genFunction, genEndFunction): do not store/restore local registers for
3807 _main (this should take care the --main-return command line option in
3809 (genOr): removed some legacy pic-port instructions,
3810 * src/pic16/genarith.c (genAddLit): re-enabled old code because
3811 performing operations with SFR's causes data to be written more than
3812 once to each SFR. Perhaps SFRs should be handled in special cases...
3813 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
3815 * src/pic16/main.c (_process_pragma): stack bound checking did not take
3816 into account for stack starting position,

3818 --extended or -y for Extended Instruction Support,
3819 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
3820 (deassignLRs): *** perhaps the most important change, old 'for' code
3821 (commented out for reference), didn't account for some registers which
3822 were left marked 'not free' after a pointer operation. The change
3823 reduces register usage a lot in some cases
3825 2006-03-04 Borut Razem <borut.razem AT siol.net>

6100 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
6101 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
6102 always available in leading double underscore form. The C99 support is
6103 mostly missing, but it's a start.
6104 * support/regression/tests/bug-227710.c: fixed nonconforming use of

6185 * device/lib/printf_large.c: removed inline assembly for portability and
6186 readability. Use printf_fast if speed or size are more important.
6187 * src/pic16/gen.c: removed conditions around use of DEBUGpc
6188 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
6190 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
6192 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
6193 prevent compiler warning
6195 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
6197 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
6198 moved to level 0 and declared as static. Also they are explicit
6199 placed in access bank. This was necessery because some times they
6200 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
6201 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
6202 optimizations. Currently only compare to unsigned char is implemented,
6203 * src/pic16/gen.c: added fReturnIdx array,
6204 * (struct resolvedIfx) is moved to gen.h and made public,
6205 * (struct _G): added sregsAlloc and sregsAllocSet fields,
6206 * (aopForSym): added an optimization to directly store in stack of
6207 the operand of a SEND iCode,
6208 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
6209 but as registers instead (AOP_REG) using the fReturnIdx array,
6210 * (pic16_freeAsmop): remove the freed register from the
6211 _G.sregsAlloc field,
6212 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
6213 a compare of 'WREG',
6214 * (pic16_popGetTempRegCond): changed function prototype, now
6215 function takes also a bitVector argument v which holds the current
6216 set of registers that are allocated for stack access by aopForSym,
6217 registers allocated in aopForSym for accessing stack symbols are not
6218 any more part of the functions usedRegs field,
6219 * (genCall): some times aopOp is called for a stack variable to be
6220 send, aopForSym might perform the push, if this is true make sure
6221 that genCall doesn't push the variable twice by testing _G.resDirect,
6222 * (genFunction): changed testing for unspecified interrupt number
6223 from 256 to INTNO_UNSPEC,
6224 * modified selection scheme of frame pointer generation. Previously
6225 if function did use local registers a frame pointer was generated,
6226 now a frame pointer is generated only if function has arguments
6227 (that need PLUSW2 register access), or has stack arguments, or the
6228 compiler is not instructed to omit the frame pointer,
6229 * (genEndFunction): before restoring local registers that were saved
6230 in the function preamble, also restore the registers that *might*
6231 have been allocated for stack access,
6232 * (genRet): removed some old comments,
6233 * (genCmp, the active (RN's) version): added a call to the
6234 pic16_genCmp_special function to perform the compare with a more
6235 robust and optimized way,
6236 * (genInline): a feature has been added in inline code generation,
6237 which allows a wildcard variable substitution when writing inline
6238 assembly. Code is incomplete and experimental therefore undocumented,
6239 * (genCast): changed order of aopOp for result and right to allow
6240 aopForSym to directly load the result if possible,
6241 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
6242 perform an optimized compare on some selected special occasions,
6243 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
6244 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
6245 generate an IVT any more,
6246 * src/pic16/main.c (pic16_optionsTable): added command line option
6248 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
6249 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
6251 * src/pic16/NOTES: Raphael Neider added in list of active developers
6252 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
6253 jumptable_end to prevent bug #,
6254 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
6255 inCond and outCond fields,
6256 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
6257 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
6258 turn off register spilling,
6259 * (packRegsForOneUse): synced with other ports' versions although it
6260 is not used currently,
6261 * (pic16_packRegisters): added an optimization while reading
6262 structure bitfields, some registers may be saved (malloc code is
6263 decreased by 80 bytes)
6265 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
6267 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
6268 left is a bitfield, if yes, then don't optimize assignment. Perhaps
6269 this can be optimized more?
6271 2005-03-10 Raphael Neider <rneider AT web.de>
6273 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
6274 genNearPointerGet): (hopefully) fixed access to bitfields via
6275 pointers (p->bitN = x; and x = p->bitN; failed)
6277 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

6909 Adding support for replacing ljmps with sjmps in jumptables
6910 generated for switch statements. For now you need to set the
6911 environment variable SDCC_SJMP_JUMPTABLE to enable this.
6912 Now 4 algorithms for mcs51 jumptable generation are used:
6913 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
6914 addresses loaded pc-relative for up to 112 cases and stack-pushing
6915 target addresses loaded with offset from dptr for up to 256 cases.

6941 Large cummulative patch for pic16 port.
6942 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
6943 to call when a stack overflow occurs,
6944 * (malloc.h): added CVS Id tag,
6945 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
6947 * added libc directory. The current version of LibC contains string
6948 functions, ctype functions and macros and some functions of the
6949 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
6950 be extensively tested in the future. Standard disclaimer here.
6951 Library is not automatically build yet. But one can build it by
6952 invoking 'make' inside the libc directory.
6953 * added ADC library under libio. Preliminary version yet.
6955 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

6962 * (genUminusFloat): fixed for pic16, ported code from mcs51,
6963 * (pic16_storeForReturn): optimized return of 0,
6964 * (genCmp): experimental code for new genCmp which uses PIC18's
6965 special compare&skip instructions. Initial tests fail some times
6966 with variables grater than 1 byte in size, so new code is disabled,
6967 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
6969 * (genCast): began a fix to optimize the casting of a bit to another
6970 bit, now assigning a bitfield to another bitfield will fail, sorry,
6971 * src/pic16/main.c: disabled the use of lr-support feature,
6972 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
6973 * added some function prototypes, added function _debugf prototype,

6975 bits with offset (case PO_GPR_BIT),
6976 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
6978 * (isBankInstruction): modified to return 0 for no banking instruction,
6979 and 1 for banking instruction,
6980 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
6981 caused stop processing pCodes after a inline assembly block,
6982 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
6983 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
6984 registers when it shouldn't,
6985 * src/pic16/ralloc.c (allocReg): add preliminary support for
6986 supporting a limited set of temporary registers,
6988 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6990 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
6991 genDataPointerSet): ensure assignments always copy in MSB to LSB
6993 (loadRegFromAop): recognize CLRH optimization,
6994 (genFunction): optimize RECEIVE iCodes in reentrant functions
6996 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6998 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

7012 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
7014 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

9993 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
9995 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
9996 loaded with the linker search paths (-L arguments) and the libraries
9997 to be linked with the current source (-l arguments). Changes
9998 currently will affect only the pic16 port.
9999 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
10000 include path the port specific paths and port specific libraries,
10001 * gplink command now contains the $3 argument,
10002 * src/pic16/device.h,
10003 * src/pic16/device.c,: structure PIC_device is made public and
10004 renamed to PIC16_device, the same for variable Pics which is renamed
10005 to Pics16. Updated all references to them.
10006 * src/pic16/glue.c (pic16glue): corrected bug with code
10007 initialization which bypassed the variable initializations block.

10017 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
10019 Documenting changes from previous commits.
10020 * configure.in (version 1.56),
10021 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
10022 when generating output files to configure the pic16 library,
10023 but now I've commented it out, since gputils aren't installed in the
10024 SF compile farm, so library won't compile
10026 * device/lib/Makefile.in (version 1.56): initially I've added in
10027 target 'all' the prerequestive 'model-pic16' so it compiled the
10028 pic16 library, but now I've commented it out for the same reasons
10030 * added targets 'model-pic16' and 'objects-pic16' to compile the
10032 * added target 'port-specific-objects-pic16' to handle the
10033 generated libraries and copy them into the build/ directory
10034 * added target 'clean-intermediate-pic16' to clean intermediate
10035 files into pic16 directory
10036 * in target 'installdirs' added line to create directory pic16 in
10037 the installation path
10039 * device/include/Makefile.in (version 1.11): in target 'install'
10040 added lines to copy all header files to installation path,
10041 * in target 'installdirs' added line create directory for pic16
10042 headers in the installation path
10044 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

10053 * device/lib/configure: fixed for autoconf 2.57
10055 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10057 * src/z80/main.c (_parseOptions): fixed the portmode= command line
10058 option so that it actually works. Made it specific to the z80, since
10059 the gbz80 doesn't have these kinds of I/O ports.
10061 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10063 * device/include/z180.h,

10072 portmode; added deprecation warning for bank= and protmode= forms.
10073 Also, guard against buffer overflow.
10074 * src/z80/gen.c (aopGet): generate better code for sfr banked read
10076 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10078 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also

10085 Mainly changes to support compilation of the device libraries
10086 * src/pic16/device.c: stack is allocated via symbol and not
10087 via literal number. The symbol is placed in the corresponding
10088 position of the data ram
10089 * (pic16_dump_section): relocatable and absolute uninitialized
10090 data are now emitted in sorted order to reduce section naming,
10091 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
10092 weren't marked as being in the access bank,
10094 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
10096 Added portion of GNU PIC Library under the directory
10097 device/include/pic16 and device/lib/pic16. These files
10098 contain the declarations of SFRs for the PIC18Fxx2 devices.
10099 The directory is initialized via configure from toplevel.
10101 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
10103 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
10104 the spilllocations to be compared correctly
10106 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
10108 * src/SDCCast.c (decorateType): fixed bug introduced today
10110 2004-01-12 Borut Razem <borut.razem AT siol.net>

10115 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
10117 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
10118 in simpler and even better code
10120 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
10122 * src/SDCCicode.c (operandOperation): fixed bug #874819
10123 * src/SDCCast.c (decorateType): fixed

10126 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10128 * doc/sdccman.lyx: Moved and added some sections, small changes
10129 all over. Telling LaTeX to be less strict with word spacing
10130 to better keep the right margin. Changed some notes about
10131 maintainance of the ports in section 3.2.1 - is it OK like this?
10133 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
10135 SDCC source changes:
10136 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

10170 UPPER for immediate operands,
10171 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
10173 * src/pic16/peeph.def: all peepholes with movff are commented out,
10174 because there is a problem in the pcode peep optimizer,
10175 * src/pic16/ralloc.c: the register allocator can now reuse local
10176 function symbols for another function. This saves register usage.
10177 * src/pic16/ralloc.h: added flag isLocal in structure regs,
10179 Added file src/pic16/NOTES with information about program writing on
10180 the current port version.

10184 * src/mcs51/peephole.def: added peepholes 177.c,d (redundant moves)
10185 and peephole 252 (array access)
10187 2004-01-09 Borut Razem <borut.razem AT siol.net>
10189 * src/SDCCmain.c : fixed #872250: -l command line defined library

10209 gen51Code): more efficient parameter receive for --model-large
10212 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10214 * src/ds390/main.c,
10215 * src/z80/main.c: added missed needLinkerScript flags (more than
10216 one port structure defined in these file)
10217 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

10237 override default uninitialized data segment definition for
10238 devices only with SHAREBANK memory (reported from Erik Epetrich)
10239 * (pic14emitOverlay): modified to emit a commented overlay segment
10240 directive when no overlay data exist
10241 * (picglue): modified to emit uninitialized data segment
10242 according to udata_section_name
10243 * src/pic/main.c (_pic14_parseOptions): added command line
10244 options --udata-section-name=[name] to override default
10245 udata definition name
10246 * modified _linkCmd and _asmCmd to include compiler passed
10247 arguments via -W option
10248 * src/pic16/main.c: added $l in _asmCmd, changed extension for

10290 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10292 A python script to validate compiler diagnostic messages. It can be
10293 used to verify that sdcc complains about bad c source code and
10294 gives a good location of the error.
10295 * support/valdiag/Makefile,
10296 * support/valdiag/valdiag.py,
10297 * support/valdiag/tests/*
10299 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10327 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
10329 PIC16 port related changes:
10330 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
10331 added variable stackPos,
10333 * gen.c: genCall, assignResultValue: added support for
10334 pushing/retrieving function parameters to/from stack,
10335 genFunction,genEndFunction: setup stack frame for the
10336 generated function,
10337 genAddrOf: will be changed according to bug 863624
10339 * added files genutils.c and genutils.h which contain gen*
10340 debugged and optimised functions extracted from gen.c
10342 * glue.c: added variable 'externs' which holds extern symbols,
10343 pic16emitRegularMap: is modified to properly handle relocatable
10344 symbols under the new scheme,
10345 pic16createInterruptVect: is modified
10346 pic16printPublics: is modified to emit 'global' assembler directives,
10347 added pic16_printExterns to print extern symbols,
10348 pic16glue: initializes stack/frame pointer in the beginning of
10349 the assembly output. Temporary hack, will be corrected later,
10350 because gplink yet does not support stack and SDCC does not
10351 yet support a type of crt0.o object to create the final binary.
10353 * Removed many lines that contain 8051 legacy code.
10354 * The code is finally placed under a 'code' directive.
10355 * Added port specific options.
10357 * _process_pragma: simplified since now we do not need *special*
10358 include file to define SFR registers. But a separate header
10359 will be needed. This will be developed later.
10360 * _pic16_parseOptions: added, parses port specific options:
10361 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
10362 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
10363 --preplace-udata-with=
10365 * _pic16_setDefaultOptions: modified to initialize section names,
10366 but hack is temporarly out of order since it needs improvement.
10367 * _pic16_genAssemblerPreamble: configuration words are emitted by
10368 their address instead of their name. This part is incomplete and
10369 supports only the 18Fxx2 devices. Other devices will emit an error
10370 during assembly since they do not contain the same set of config
10372 * _pic16_genIVT: is modified,
10374 * pcode.c: added definitions for some hardware registers that are needed
10376 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
10377 All PCI entries are updated. Now LFSR is supported.
10378 * Removed pic16_pciTRIS is mentioned by mdubuc in source
10379 * added pic16_newpCodeOpLit2 to support instructions with
10380 two literal arguments
10381 * pic16_pCode2str: corrected code that emits assembler instructions
10382 with two literal operands and those that have an access bit modifier
10383 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
10384 this fixes a bug which caused some labels to be lost, when an
10385 assembler directive was added, i.e. banksel,
10386 * pic16_FixRegisterBanking: improved logic that causes the insertion
10388 * InlineFunction: functions that are called once, are not any more
10389 inlined. This can be a port option in the future,
10391 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
10393 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
10394 hold the corresponding uninitialized symbols,
10395 * pic16_allocProcessorRegister: registers have explicit marked the
10397 * pic16_allocInternalRegister: registers are explicit marked as
10399 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
10400 processing list, so bit registers were lost,
10403 * ralloc.h: added field 'accessBank' and original symbol operand
10404 in register definition,
10405 * removed the field isMapped from register definition,
10407 ** Several functions have been removed from various sources:
10408 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
10409 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
10410 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
10411 pic16_assignRelocatableRegisters
10413 ** others have been introduced:
10414 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
10415 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
10417 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
10419 * support/scripts/inc2h.pl: changed definition of BIT_AT
10420 to emit 'sbit at' instead of 'bit at'. This was a request.
10422 PIC16 port related preliminary changes:
10423 * gen.c: prefixed function popRegFromString with
10424 pic16_ and all references to it corrected
10425 * pcode.c: all pic16_pc_* hardware registers prefixed
10426 with underscore (_),
10427 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
10428 * ralloc.c: newReg(): when register is REG_SFR then
10429 set address to rIdx,
10430 pic16_allocProcessorRegister(): marks register wasUsed=0
10431 pic16_writeUsedRegs(): added a call to assign processor
10432 registers via pic16_assignFixedRegisters
10434 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10436 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
10437 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
10438 variables in unused register banks. Also the SSEG is placed
10439 wherever there is enough space for it, and IDATA can be anywhere
10440 in internal RAM. For now compile using -Wl-Y[stack_size].
10441 The mem file is different for this option as well, since it
10442 makes no sense of talking about DSEG lenght.

11430 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
11432 * device/lib/_mullong.c: replaced int by short for gcc
11434 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11436 * src/SDCCpeeph.c (notVolatile, notVolatileVariable): handle IFX
11437 and JUMPTABLE iCodes properly now (worked by accident before)
11438 * src/mcs51/gen.c (leftRightUseAcc),
11439 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
11440 iCode properly now. Use getSize instead of nRegs since a & b
11441 aren't part of the nRegs tally.
11443 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
11445 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

11455 copied from genNearPointerSet()
11456 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
11457 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
11458 If they pop r0/r1 they must be called in the opposite order than aopOp().
11459 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
11460 (resp. --stack-auto), prepared for --xstack
11462 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11464 * doc/sdccman.lyx: reverted tables to those in cvs 1.64
11466 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>

11471 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
11473 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11474 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
11475 type for bits was changed. It resulted in bit variables becoming
11476 global, which is not permitted in PIC 14 assembly output.
11478 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11480 * doc/sdccman.lyx: various additions and updates. Rearranged sections
11482 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11484 Z80 and MCS51 linkers complaint if a public symbol is defined
11485 in more than one library module:
11489 * as/mcs51/Makefile.in
11491 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11493 A few small changes that speed up the peephole optimizer.
11497 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11499 Try to make the peephole optimizer smarter by maintaining
11500 an association between the assembly source code and the
11501 iCodes that originated them. Put this information to use
11502 with a new peephole rule condition "notVolatile" so that
11503 the rules can be aggressive yet still safe.
11508 * src/mcs51/peeph.def
11510 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11514 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
11515 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
11516 if the left or right operand symbols have the accuse flag set.
11518 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11520 Changed the type of the result of the ! (NOT) operator to char;
11521 previously it returned the same type as the source. This allows
11522 us to eliminate all the genFloatNot functions (all of its target
11523 implementations were very buggy) since !float can use the same
11526 * src/SDCCicode.c (ast2iCode): ! returns char
11527 * src/mcs51/gen.c (genNot, genNotFloat),
11528 * src/ds390/gen.c (genNot, genNotFloat),
11529 * src/z80/gen.c (genNot, genNotFloat),
11530 * src/pic/gen.c (genNot, genNotFloat),
11531 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
11533 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
11535 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11536 1. Interrupt would not compile properly. Ensure PCLATH register is saved
11537 during interrupts. Ensure WSAVE is located at a shared bank address.
11538 2. Fixed page selection in some places
11539 3. Fixed BTFSS/C to where necessary use registers directly and not simply
11540 the registers name strings.
11541 4. Fixed "signed / unsigned compare" compiler warnings.
11542 5. The PIC port manages its own allocation of the general purpose
11543 registers, but makes no attempt to reuse them. As a result when
11544 compiling it soon runs out of general purpose registers. Some
11545 additional code was added to the files pcode.c and device.c to walk
11546 through the function call tree and rename the registers so that they
11556 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
11557 genPlus() & genMinus() when the result is the same as left or right
11559 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

11563 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11565 Made bitfield a distinct type from bit so that bitfields
11566 convert as per ANSI C and bits retain their traditional
11567 boolean style behaviour. Implemented bitfield support in
11575 * src/ds390/gen.c: bit v bitfield split
11576 * src/z80/gen.c: New support for bitfields
11577 * support/regression/tests/bitfields.c: reenabled z80,
11580 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11582 Rules 246.x, 247.x relate to bitfields, the others speed up
11583 access to xdata mapped I/O devices.
11585 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
11587 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11589 Cleaned up genPackBits and genUnpackBits and added two helper
11590 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
11591 for literal assignments in genPackBits (thanks to Frieder for
11597 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11599 Fixed bug #748310 (pointer to function type mishandled when the
11600 function name is omitted). Also fixed a SIGSEGV when a function
11601 attribute (reentrant, etc) is used on a non-function or on a
11602 function but misplaced before the parameter list.
11604 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
11606 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
11607 * support/Util/SDCCerr.h,
11608 * support/Util/SDCCerr.c: Added func attr misuse error msg
11610 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
11612 Fixed bug #787649 by anonymous
11613 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
11614 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
11616 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11618 Fixed numerous bitfield problems.

11629 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11631 Made the constant following the "interrupt" keyword optional. If
11632 omitted, the function will not automatically be given an entry
11633 in the interrupt vector table (similar to #pragma NOIV, but
11634 less syntacticly kludgy). The interrupt number is also now
11635 range checked. Also fixed a bug in the high order bit example
11642 * support/Util/SDCCerr.c
11643 * support/Util/SDCCerr.h
11646 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

11649 * src/SDCCicode.c (operandOperation): rewritten some ops
11650 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
11651 * src/SDCCsymt.c (computeType): literals are handled the same way as any
11653 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
11654 be re-activated by defining REDUCE_LITERALS)
11655 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
11656 unsigned, but are signed by default
11657 * src/SDCCval.c (constVal): rearranged
11658 * src/SDCCval.c (valMod): preliminary fix
11659 * src/SDCCval.c (valCastLiteral): use TYPE_* types

11699 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
11700 * src/SDCCval.c (constVal): changed default to signed; hex and octal
11701 constants are unsigned; added recognition of "u" flag for unsigned
11702 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
11703 * src/SDCCval.c (valDiv, valMod): fixed signdness

12112 the regression tests I'm not brave enough to enable 245.b, 245.c
12113 * doc/sdccman.lyx: added latex preamble for hyperref package.
12114 Using pdflatex this will give you a hyperlinked pdf file with

12165 added if/endif conditional macros to remove options help
12166 messages from optionsTable when a port is not configured, added
12167 support for the PIc16 port in the ports table, when executing
12168 the compiler with no port specified on command line, a default
12169 port is selected with the new macro DEFAULT_PORT which is
12170 defined in port.h, in setDefaultOptions() linkOptions is removed
12171 from initialization assignment, since now it is a set,
12172 parseCmdLine uses setParseWithComma for linkOptions, in
12173 linkEdit() linkOptions are accessed with new function indexSet()
12174 which returns the i'th item of a set variable. See SDCCset.c, in
12175 linkEdit() when calling buildCmdLine(), added linkOptions as
12176 last argument. Now users can pass arguments to gplink via the
12177 -Wl option, main() uses pic16glue() to glue up pic16 programs

12190 * src/pic16/main.c: __config directives are commented out to stop
12191 gpasm complaining and test the linkage with gplink, _linkCmd and
12192 _asmCmd changed to be more gplink and gpasm friendly
12193 * src/pic16/peeph.def: peep rule 3 is commented out, since it
12194 produced an error when parsed, peep rule 12 is added to utilize
12195 movff, but it is commented out since the pCode does not support
12196 yet a command with 2 address arguments
12198 2003-05-18 <johan AT balder>
12200 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

12227 2003-05-11 Borut Razem <borut.razem AT siol.net>
12229 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

13216 * src/mcs51/gen.c (genPlus): replaced "mov b,acc" by "mov b,a" Fiorenzo D. Ramaglia <fd.ramaglia AT tin.it>
13218 2003-01-07 <johan AT balder>
13220 * src/SDCCast.c (decorateType): fixed bug #600035
13222 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
13223 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings
13224 * as/mcs51/lkaomf51.c: #include <ctype.h> to remove warnings
13225 * src/pic/main.c (_hasNativeMulFor): outcommented unused variables to remove warnings
13226 * src/pic/pcode.c: outcommented unused variable to remove warnings
13227 * src/pic/ralloc.c: outcommented unused variable to remove warnings
13229 2003-01-06 <karl AT turbobit.com>
13230 * sim/ucsim/cmd.src/command.cc: fixed so "break xram r 0x7654" works again in
13233 2003-01-06 <johan AT balder>
13235 * src/SDCCicode.c: fixed array add
13237 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
13238 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
13239 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
13241 2003-01-04 <johan AT balder>
13243 * src/SDCCval.c (getNelements): fixed the initialized array of structures
13245 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13246 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
13248 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
13249 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
13250 * support/regression/tests/bug-524697.c: fit mem usage into 8032
13252 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
13253 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
13255 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
13256 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
13258 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
13259 * src/mcs51/main.c: removed {bindir}{sep} from aslink
13261 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13263 * in /sdcc/as/mcs51/ changed these files in order to create an
13264 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
13265 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
13266 following files to include the previous two files: aslink.dsp,
13267 Makefile.aslink, Makefile.bcc, and Makefile.in.
13269 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
13270 .adb instead of .cdb
13272 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13274 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
13275 value from option --iram-size.
13277 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13279 * /sdcc/as/mcs51/lklist.c: added boundary check before using
13282 2002-09-18 <wiml AT hhhh.org>
13284 * SDCClrange.h: exposed setFromRange() and setToRange()
13285 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
13286 packRegsForAccUse() (bug 542397)
13287 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
13288 multiple times and emitting the fetch operations more than once
13289 added aopGetUsesAcc() function to allow binary operators to
13290 fetch their operands in the correct order; made genMinus() emit
13291 compact code for X = LITERAL - Y
13293 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13294 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
13295 sprintf() in line 1267.
13297 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13298 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
13301 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13302 Changes to aslink (All the changes are marked with 'JCF'):
13304 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
13307 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
13308 area BSEG. Also moves, if possible, the DATA area down into the internal
13309 ram so more space is available.
13311 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
13314 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
13315 not bytes. Function summary() which creates a memory usage summary
13316 file with extension .mem. Reports of overlaping stack and small stack
13317 size. If the space for the stack is less than 16 bytes aslink trows a
13320 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
13321 the 8051. Option 'y' for memory summary output file.
13323 Changes to sdcc (All the changes are marked with 'JCF'):
13325 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
13327 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
13328 overlaying area for it (uses RegBankUsed[4]).
13330 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
13331 bank zero as used by default. By default aslink locates the stack
13332 (equivalent to --stack-after-data). Pass option 'y' to aslink for
13333 the creation of the .mem file. Delegates the allocation of data area
13334 to aslink (it is not longer 0x30 by default). If --stack-loc passes
13335 the begining of the stack area to aslink.
13337 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
13338 glue() in SDCCglue.c creates an area for it.
13340 2002-09-03 Borut Razem <borut.razem AT siol.net>
13341 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
13342 sdcc/src/pic/glue.c:
13343 introduced atexit() handler for teporay files removal in case of
13344 errors, assertions, ...
13346 2002-08-29 Borut Razem <borut.razem AT siol.net>
13347 * sdcc/support/cpp2/auto-host_vc_in.h:
13348 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
13349 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
13350 Maybe there is a similar problem with BORLANDC? It should be checked!
13352 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
13353 corrected improper use of assert: the assignment to clr variable was done inside the assert.
13354 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
13355 was not executed, and the compiler (cl) launched a warning:
13356 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
13358 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
13359 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
13361 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
13362 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
13364 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
13365 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
13366 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
13367 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
13368 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
13369 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
13370 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
13371 - added Release configuration in VS projects
13372 - review of compiler an linker options
13373 - VC .exe files are generated in bin_vc directory, not to interfere
13374 with binaries generated from other projects (cygwin, mingw, bcc ...)
13376 * sdcc/src/yacc.dsp: added
13378 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
13379 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
13380 and insert the version number definitions from .version
13382 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
13384 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
13385 added - genarate auto-host.h using auto-host_vc_in.h as template
13388 removed from CVS, generated automatically
13390 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
13391 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
13393 2002-08-11 Borut Razem <borut.razem AT siol.net>
13394 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
13396 2002-08-10 Borut Razem <borut.razem AT siol.net>
13397 * src/SDCCmain.c (main):
13398 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
13399 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
13400 The consequence was that some temporary files were not removed.
13403 unification of code in functions tempfilename() and tempfile():
13404 function tempnam() is defined in Visual Studio 6.0 and .NET
13406 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
13408 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
13409 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
13410 - removed compiler command line option /WX: Treats all warnings as errors
13411 - update a list of source files, included into the project
13413 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
13414 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
13415 changed project type to Generic Project so that can be correcly converted to VS.NET project
13417 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
13419 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
13421 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
13423 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
13424 added return 0 statements after assert() to make compiler happy
13426 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
13427 added newline in the def file to keep MSC compiler satisfied
13429 * sdcc/src/z80/gen.c:
13430 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
13431 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
13432 - solved MSC error in function aopDump()
13434 * sdcc_vc.h: define PREFIX as "\\sdcc"
13436 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
13437 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
13439 2002-06-22 Scott Dattalo <scott AT dattalo.com>
13440 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
13441 - Rewrote the register banking algorithm.
13442 - Added pCode live-range analysis to registers (for now, only non-used and
13443 singly-used registers optimized away)
13445 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
13447 * support/scripts/inc2h.pl Kevin L. Pauba <klpauba AT cox.net> submitted this perl script for converting MicroChip include files into SDCC Pic include files.

13464 * device/lib/z80/printf.c (sprintf): Added.
13466 * src/z80/ralloc.c (packRegisters): Disabled pack HL use for GB as it's broken.
13468 * src/z80/peeph.def: Added transpose redundent load rule.
13470 * src/z80/main.c: Added force callee saves for jaune.
13472 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
13474 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
13476 2002-03-28 Johan Knol <johan AT balder>
13478 * src/SDCCval.c: fixed bug #532436
13480 2002-03-14 Scott Dattalo <scott AT dattalo.com>
13482 Added "char *Processor" field to the port structure.
13485 Added -p option. Allows port dependent processor to be specified.
13488 Initialized the new field char *Processor field to NULL in all ports
13491 Compiler generated registers for interrupt context saving
13492 were not getting allocated.
13494 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
13497 Fixed left shift. Will promote the left side of a left shift
13498 if a) left shifting more than size of operand or b) when assigned
13499 to something size > size of left side
13501 2002-03-14 Scott Dattalo <scott AT dattalo.com>
13503 tons of changes. Register allocation has been
13504 rewritten. Added customization for the various PICs. Flow
13505 analysis is restructured. ...
13507 * src/pic/device.h:
13510 * src/pic/device.c:
13511 Added. device.c is a PIC port hack to accomodate variations
13514 2002-03-13 Michael Hope <michaelh AT vroom>
13516 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
13518 2002-03-04 johanknol <johanknol AT manik>
13520 * /src/SDCCval.c: fixed
13522 const unsigned char arr[][2] = { { 0, 1 } };
13523 t18.c:1: error: Initializer element is not constant
13525 2002-03-04 bela <bela AT manik>

13583 2002-03-01 <johan AT FRIJA>
13585 * src/SDCCglue.c (printIvalPtr): fixed bug #524211
13587 * src/SDCCast.c (decorateType): fixed bug #524209

13609 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
13611 * sdcc/src/SDCCloop.c:
13612 Previous fix was not good. basic blocks that have "break" or "return" are
13613 not really partof a loop , but live ranges used in these blocks should
13614 be live thru the entire loop, so set partOfLoop but don't add them to
13617 2002-02-21 <johan AT FRIJA>
13619 * src/SDCCcse.c: fixed bug #514308
13621 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
13624 Fixed BUG #519583. If a conditional block ended in a return/break
13625 statement inside a loop, it was not being considered part of the loop.
13627 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
13629 2002-02-10 Karl Bongers <karl AT turbobit.com>
13632 Fixed up SDCDB debugger somewhat. Updated debugger/README
13633 with lots of comments and notes.
13635 * device/examples/test2.c:
13636 Fix bug, "red" variable not being initialized(compiler complained).
13638 * device/examples/Makefile, examples/test3.c:
13639 Add Makefile in device/examples folder, compiles test3.c
13640 for use as a multiple module SDCDB test case.
13642 * sim/ucsim/cmd.src/cmdset.cc:
13643 Took out debug printfs in ucsim "next" command.
13645 * sim/ucsim/xa.src:
13646 Karl and Johan start ucsim XA support. Most dissassembly working,
13647 about 75% emulation done(plenty of work remaining).
13649 * sim/ucsim/z80.src:
13650 Add Z80 support to ucsim, add test-ucz80 regression test,
13651 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
13652 Notice z80 compiler fails on examples/test3.c/crc code.
13654 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
13656 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:
13657 Added support for --parms-in-bank1
13659 * src/ds390/peeph.def:
13660 added a few more peephole optimzations
13662 * src/ds390/main.c:
13663 1) added __builtin_inp & __builtin_outp used to read in data of given length
13664 from a memory mapped port
13665 2) added __builtin_memcmp
13666 3) added __builtin_swapw swap bytes of a short
13668 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
13669 1) handle multiple send & receives from register bank1
13670 2) ralloc can now allocate DPTR1 to some liveRanges
13672 * src/SDCCsymt.c, src/SDCCsymt.h:
13673 changes to handle multiple sends & receives
13675 * src/SDCCptropt.h:
13676 added some pointer arithmetic optimization
13678 * src/SDCCptropt.c:
13679 added some pointer arithmetic optimizations but not stable yet so not
13680 called from anywhere (will get this working shortly)
13682 * src/SDCCopt.c: fixed for multiple sends & receives
