3400 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
3402 Enabled VPATH feature: changed nearly all Makefiles (149 files).
3403 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
3405 One basic decision: e.g. src/clean.mk includes further files. In order
3406 to make this work there are two solutions:
3407 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
3408 run configure on them. This way they can use
3409 'include $(srcdir)/port-clean.mk'
3410 - always include clean.mk by the Makefile at the same level. To avoid
3411 that `make clean` tries to include and build Makefile.dep the
3412 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
3413 implemented, because now even `make uninstall` doesn't create
3414 Makefile.in. clean.mk could be eliminated by pasting it in
3417 * debugger/mcs51/Makefile.in: build own objects from library sources
3418 (SLIB, SDCC) in current directory
3420 * configure, configure.in: renamed --disable-device-lib-build in
3421 --disable-device-lib; added --enable-doc, the required tools are
3422 searched by configure; added result message; the toolchain for the
3423 belonging ports are now only built, if the port is enabled.
3425 * support/regression/*: all output is written in directory gen, because
3426 the fwk and ports directories don't livet in the build tree using vpath
3428 * doc/sdccman.lyx: renamed --disable-device-lib-build to
3429 --disable-device-lib, added --enable-doc, added section VPATH
3431 * sim/ucsim/configure.in,
3432 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
3433 z80 are enabled by default
3435 2006-04-24 Raphael Neider <rneider AT web.de>
3437 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
3438 to config word, "pic14_"-prefixed some extern functions
3439 (pic14_emitConfigWord): emit __config directive(s) if assignment to
3440 config word has been found
3441 * src/pic/device.h: added prototypes
3442 * src/pic/pcode.c: added "pic14_"-prefix where needed
3443 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
3445 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
3447 (pic14emitRegularMap): ignore config words,
3448 (pic14createInterruptVect): moved generating __config directives away
3449 (picglue): have __config directives emitted
3451 2006-04-24 Borut Razem <borut.razem AT siol.net>
3453 * doc/Makefile: sync with nightly build makefile
3455 2006-04-24 Raphael Neider <rneider AT web.de>
3457 * src/pic/pcoderegs.c (OptimizeRegUsage): do not optimize
3458 registers that have not been assigned proper liveranges,
3459 fixes #1469504 and #1474602,
3460 (pCodeRegOptimizeRegUsage): fixed typo in comment
3462 2006-04-24 Borut Razem <borut.razem AT siol.net>
3464 * device/examples/main8051.c: deleted - it was removed from CVS
3465 24.mar.2000 and after that modified 18.feb.2001, so it reappered
3466 after the transition to Subversion
3467 * src/SDCCalloc.h: deleted - it was removed from CVS
3468 3.feb.2001 and after that modified 18.feb.2001, so it reappered
3469 after the transition to Subversion

3707 interrupts need an interrupt number now if they are made critical),
3708 and enabled nesting of critical functions though not for gbz80
3709 (genCritical, genEndCritical): added functions
3710 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
3711 * src/z80/mappings.i: added "ei" to all mappings

3723 the left operand is shorter than the result (c* = lit-c* + int),
3725 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
3728 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3730 * src/.version: increased version number to 2.5.5
3731 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
3732 linking is done manually in pic16 port's _linkEdit,
3733 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
3734 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
3735 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
3736 allocate asmop as AOP_ACC,
3737 (aopForRemat): added parameter 'bool result' in function declaration,
3738 (pic16_aopGet): return AOP_ACC when accessing WREG,
3739 (pic16_popGetTempReg): minor modification,

3750 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
3751 call to allocReg, not by manually allocating a new one,
3752 (pic16_assignRegisters): now before going through the register
3753 allocating functions mark all registers as free. This eliminates some
3754 side effects resulting from peephole parser done earlier in the backbone
3756 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

3814 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
3815 which dumps before the function entry point a data byte which represents
3816 the number of the local variables used by the specified function, added
3817 'xinst' for initial support for Extended Instruction Support,
3818 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
3819 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
3820 port->fun_prefix anymore (may change later),
3821 (genFunction, genEndFunction): do not store/restore local registers for
3822 _main (this should take care the --main-return command line option in
3824 (genOr): removed some legacy pic-port instructions,
3825 * src/pic16/genarith.c (genAddLit): re-enabled old code because
3826 performing operations with SFR's causes data to be written more than
3827 once to each SFR. Perhaps SFRs should be handled in special cases...
3828 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
3830 * src/pic16/main.c (_process_pragma): stack bound checking did not take
3831 into account for stack starting position,

3833 --extended or -y for Extended Instruction Support,
3834 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
3835 (deassignLRs): *** perhaps the most important change, old 'for' code
3836 (commented out for reference), didn't account for some registers which
3837 were left marked 'not free' after a pointer operation. The change
3838 reduces register usage a lot in some cases
3840 2006-03-04 Borut Razem <borut.razem AT siol.net>

6114 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
6115 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
6116 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
6117 always available in leading double underscore form. The C99 support is
6118 mostly missing, but it's a start.
6119 * support/regression/tests/bug-227710.c: fixed nonconforming use of

6198 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
6200 * device/lib/printf_large.c: removed inline assembly for portability and
6201 readability. Use printf_fast if speed or size are more important.
6202 * src/pic16/gen.c: removed conditions around use of DEBUGpc
6203 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
6205 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
6207 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
6208 prevent compiler warning
6210 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
6212 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
6213 moved to level 0 and declared as static. Also they are explicit
6214 placed in access bank. This was necessery because some times they
6215 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
6216 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
6217 optimizations. Currently only compare to unsigned char is implemented,
6218 * src/pic16/gen.c: added fReturnIdx array,
6219 * (struct resolvedIfx) is moved to gen.h and made public,
6220 * (struct _G): added sregsAlloc and sregsAllocSet fields,
6221 * (aopForSym): added an optimization to directly store in stack of
6222 the operand of a SEND iCode,
6223 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
6224 but as registers instead (AOP_REG) using the fReturnIdx array,
6225 * (pic16_freeAsmop): remove the freed register from the
6226 _G.sregsAlloc field,
6227 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
6228 a compare of 'WREG',
6229 * (pic16_popGetTempRegCond): changed function prototype, now
6230 function takes also a bitVector argument v which holds the current
6231 set of registers that are allocated for stack access by aopForSym,
6232 registers allocated in aopForSym for accessing stack symbols are not
6233 any more part of the functions usedRegs field,
6234 * (genCall): some times aopOp is called for a stack variable to be
6235 send, aopForSym might perform the push, if this is true make sure
6236 that genCall doesn't push the variable twice by testing _G.resDirect,
6237 * (genFunction): changed testing for unspecified interrupt number
6238 from 256 to INTNO_UNSPEC,
6239 * modified selection scheme of frame pointer generation. Previously
6240 if function did use local registers a frame pointer was generated,
6241 now a frame pointer is generated only if function has arguments
6242 (that need PLUSW2 register access), or has stack arguments, or the
6243 compiler is not instructed to omit the frame pointer,
6244 * (genEndFunction): before restoring local registers that were saved
6245 in the function preamble, also restore the registers that *might*
6246 have been allocated for stack access,
6247 * (genRet): removed some old comments,
6248 * (genCmp, the active (RN's) version): added a call to the
6249 pic16_genCmp_special function to perform the compare with a more
6250 robust and optimized way,
6251 * (genInline): a feature has been added in inline code generation,
6252 which allows a wildcard variable substitution when writing inline
6253 assembly. Code is incomplete and experimental therefore undocumented,
6254 * (genCast): changed order of aopOp for result and right to allow
6255 aopForSym to directly load the result if possible,
6256 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
6257 perform an optimized compare on some selected special occasions,
6258 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
6259 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
6260 generate an IVT any more,
6261 * src/pic16/main.c (pic16_optionsTable): added command line option
6263 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
6264 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
6266 * src/pic16/NOTES: Raphael Neider added in list of active developers
6267 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
6268 jumptable_end to prevent bug #,
6269 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
6270 inCond and outCond fields,
6271 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
6272 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
6273 turn off register spilling,
6274 * (packRegsForOneUse): synced with other ports' versions although it
6275 is not used currently,
6276 * (pic16_packRegisters): added an optimization while reading
6277 structure bitfields, some registers may be saved (malloc code is
6278 decreased by 80 bytes)
6280 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
6282 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
6283 left is a bitfield, if yes, then don't optimize assignment. Perhaps
6284 this can be optimized more?
6286 2005-03-10 Raphael Neider <rneider AT web.de>
6288 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
6289 genNearPointerGet): (hopefully) fixed access to bitfields via
6290 pointers (p->bitN = x; and x = p->bitN; failed)
6292 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

6924 Adding support for replacing ljmps with sjmps in jumptables
6925 generated for switch statements. For now you need to set the
6926 environment variable SDCC_SJMP_JUMPTABLE to enable this.
6927 Now 4 algorithms for mcs51 jumptable generation are used:
6928 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
6929 addresses loaded pc-relative for up to 112 cases and stack-pushing
6930 target addresses loaded with offset from dptr for up to 256 cases.

6957 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
6958 to call when a stack overflow occurs,
6959 * (malloc.h): added CVS Id tag,
6960 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
6962 * added libc directory. The current version of LibC contains string
6963 functions, ctype functions and macros and some functions of the
6964 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
6965 be extensively tested in the future. Standard disclaimer here.
6966 Library is not automatically build yet. But one can build it by
6967 invoking 'make' inside the libc directory.
6968 * added ADC library under libio. Preliminary version yet.
6970 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

6977 * (genUminusFloat): fixed for pic16, ported code from mcs51,
6978 * (pic16_storeForReturn): optimized return of 0,
6979 * (genCmp): experimental code for new genCmp which uses PIC18's
6980 special compare&skip instructions. Initial tests fail some times
6981 with variables grater than 1 byte in size, so new code is disabled,
6982 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
6984 * (genCast): began a fix to optimize the casting of a bit to another
6985 bit, now assigning a bitfield to another bitfield will fail, sorry,
6986 * src/pic16/main.c: disabled the use of lr-support feature,
6987 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

6990 bits with offset (case PO_GPR_BIT),
6991 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
6993 * (isBankInstruction): modified to return 0 for no banking instruction,
6994 and 1 for banking instruction,
6995 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
6996 caused stop processing pCodes after a inline assembly block,
6997 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
6998 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
6999 registers when it shouldn't,
7000 * src/pic16/ralloc.c (allocReg): add preliminary support for
7001 supporting a limited set of temporary registers,
7003 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7005 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
7006 genDataPointerSet): ensure assignments always copy in MSB to LSB
7008 (loadRegFromAop): recognize CLRH optimization,
7009 (genFunction): optimize RECEIVE iCodes in reentrant functions
7011 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7013 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

10008 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
10010 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
10011 loaded with the linker search paths (-L arguments) and the libraries
10012 to be linked with the current source (-l arguments). Changes
10013 currently will affect only the pic16 port.
10014 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker

10016 * gplink command now contains the $3 argument,
10017 * src/pic16/device.h,
10018 * src/pic16/device.c,: structure PIC_device is made public and
10019 renamed to PIC16_device, the same for variable Pics which is renamed
10020 to Pics16. Updated all references to them.
10021 * src/pic16/glue.c (pic16glue): corrected bug with code
10022 initialization which bypassed the variable initializations block.

10032 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
10034 Documenting changes from previous commits.
10035 * configure.in (version 1.56),
10036 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
10037 when generating output files to configure the pic16 library,
10038 but now I've commented it out, since gputils aren't installed in the
10039 SF compile farm, so library won't compile
10041 * device/lib/Makefile.in (version 1.56): initially I've added in
10042 target 'all' the prerequestive 'model-pic16' so it compiled the
10043 pic16 library, but now I've commented it out for the same reasons
10045 * added targets 'model-pic16' and 'objects-pic16' to compile the
10047 * added target 'port-specific-objects-pic16' to handle the
10048 generated libraries and copy them into the build/ directory
10049 * added target 'clean-intermediate-pic16' to clean intermediate
10050 files into pic16 directory
10051 * in target 'installdirs' added line to create directory pic16 in
10052 the installation path
10054 * device/include/Makefile.in (version 1.11): in target 'install'
10055 added lines to copy all header files to installation path,
10056 * in target 'installdirs' added line create directory for pic16
10057 headers in the installation path
10059 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

10070 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10072 * src/z80/main.c (_parseOptions): fixed the portmode= command line
10073 option so that it actually works. Made it specific to the z80, since
10074 the gbz80 doesn't have these kinds of I/O ports.
10076 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10078 * device/include/z180.h,

10087 portmode; added deprecation warning for bank= and protmode= forms.
10088 Also, guard against buffer overflow.
10089 * src/z80/gen.c (aopGet): generate better code for sfr banked read
10091 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10093 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also

10100 Mainly changes to support compilation of the device libraries
10101 * src/pic16/device.c: stack is allocated via symbol and not
10102 via literal number. The symbol is placed in the corresponding
10103 position of the data ram
10104 * (pic16_dump_section): relocatable and absolute uninitialized
10105 data are now emitted in sorted order to reduce section naming,
10106 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
10107 weren't marked as being in the access bank,
10109 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
10111 Added portion of GNU PIC Library under the directory
10112 device/include/pic16 and device/lib/pic16. These files
10113 contain the declarations of SFRs for the PIC18Fxx2 devices.
10114 The directory is initialized via configure from toplevel.
10116 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
10118 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
10119 the spilllocations to be compared correctly
10121 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
10123 * src/SDCCast.c (decorateType): fixed bug introduced today
10125 2004-01-12 Borut Razem <borut.razem AT siol.net>

10130 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
10132 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
10133 in simpler and even better code
10135 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
10137 * src/SDCCicode.c (operandOperation): fixed bug #874819
10138 * src/SDCCast.c (decorateType): fixed

10143 * doc/sdccman.lyx: Moved and added some sections, small changes
10144 all over. Telling LaTeX to be less strict with word spacing
10145 to better keep the right margin. Changed some notes about
10146 maintainance of the ports in section 3.2.1 - is it OK like this?
10148 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

10184 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
10185 UPPER for immediate operands,
10186 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
10188 * src/pic16/peeph.def: all peepholes with movff are commented out,
10189 because there is a problem in the pcode peep optimizer,
10190 * src/pic16/ralloc.c: the register allocator can now reuse local
10191 function symbols for another function. This saves register usage.
10192 * src/pic16/ralloc.h: added flag isLocal in structure regs,
10194 Added file src/pic16/NOTES with information about program writing on
10195 the current port version.

10199 * src/mcs51/peephole.def: added peepholes 177.c,d (redundant moves)
10200 and peephole 252 (array access)
10202 2004-01-09 Borut Razem <borut.razem AT siol.net>
10204 * src/SDCCmain.c : fixed #872250: -l command line defined library

10224 gen51Code): more efficient parameter receive for --model-large
10227 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10229 * src/ds390/main.c,
10230 * src/z80/main.c: added missed needLinkerScript flags (more than
10231 one port structure defined in these file)
10232 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

10253 devices only with SHAREBANK memory (reported from Erik Epetrich)
10254 * (pic14emitOverlay): modified to emit a commented overlay segment
10255 directive when no overlay data exist
10256 * (picglue): modified to emit uninitialized data segment
10257 according to udata_section_name
10258 * src/pic/main.c (_pic14_parseOptions): added command line
10259 options --udata-section-name=[name] to override default
10260 udata definition name
10261 * modified _linkCmd and _asmCmd to include compiler passed
10262 arguments via -W option
10263 * src/pic16/main.c: added $l in _asmCmd, changed extension for

10342 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
10344 PIC16 port related changes:
10345 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
10346 added variable stackPos,
10348 * gen.c: genCall, assignResultValue: added support for
10349 pushing/retrieving function parameters to/from stack,
10350 genFunction,genEndFunction: setup stack frame for the
10351 generated function,
10352 genAddrOf: will be changed according to bug 863624
10354 * added files genutils.c and genutils.h which contain gen*
10355 debugged and optimised functions extracted from gen.c
10357 * glue.c: added variable 'externs' which holds extern symbols,
10358 pic16emitRegularMap: is modified to properly handle relocatable
10359 symbols under the new scheme,
10360 pic16createInterruptVect: is modified
10361 pic16printPublics: is modified to emit 'global' assembler directives,
10362 added pic16_printExterns to print extern symbols,
10363 pic16glue: initializes stack/frame pointer in the beginning of
10364 the assembly output. Temporary hack, will be corrected later,
10365 because gplink yet does not support stack and SDCC does not
10366 yet support a type of crt0.o object to create the final binary.
10368 * Removed many lines that contain 8051 legacy code.
10369 * The code is finally placed under a 'code' directive.
10370 * Added port specific options.
10372 * _process_pragma: simplified since now we do not need *special*
10373 include file to define SFR registers. But a separate header
10374 will be needed. This will be developed later.
10375 * _pic16_parseOptions: added, parses port specific options:
10376 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
10377 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
10378 --preplace-udata-with=
10380 * _pic16_setDefaultOptions: modified to initialize section names,
10381 but hack is temporarly out of order since it needs improvement.
10382 * _pic16_genAssemblerPreamble: configuration words are emitted by
10383 their address instead of their name. This part is incomplete and
10384 supports only the 18Fxx2 devices. Other devices will emit an error
10385 during assembly since they do not contain the same set of config
10387 * _pic16_genIVT: is modified,
10389 * pcode.c: added definitions for some hardware registers that are needed
10391 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
10392 All PCI entries are updated. Now LFSR is supported.
10393 * Removed pic16_pciTRIS is mentioned by mdubuc in source
10394 * added pic16_newpCodeOpLit2 to support instructions with
10395 two literal arguments
10396 * pic16_pCode2str: corrected code that emits assembler instructions
10397 with two literal operands and those that have an access bit modifier
10398 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
10399 this fixes a bug which caused some labels to be lost, when an
10400 assembler directive was added, i.e. banksel,
10401 * pic16_FixRegisterBanking: improved logic that causes the insertion
10403 * InlineFunction: functions that are called once, are not any more
10404 inlined. This can be a port option in the future,
10406 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
10408 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
10409 hold the corresponding uninitialized symbols,
10410 * pic16_allocProcessorRegister: registers have explicit marked the
10412 * pic16_allocInternalRegister: registers are explicit marked as
10414 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
10415 processing list, so bit registers were lost,
10418 * ralloc.h: added field 'accessBank' and original symbol operand
10419 in register definition,
10420 * removed the field isMapped from register definition,
10422 ** Several functions have been removed from various sources:
10423 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
10424 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
10425 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
10426 pic16_assignRelocatableRegisters
10428 ** others have been introduced:
10429 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
10430 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
10432 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
10434 * support/scripts/inc2h.pl: changed definition of BIT_AT
10435 to emit 'sbit at' instead of 'bit at'. This was a request.
10437 PIC16 port related preliminary changes:
10438 * gen.c: prefixed function popRegFromString with
10439 pic16_ and all references to it corrected
10440 * pcode.c: all pic16_pc_* hardware registers prefixed
10441 with underscore (_),
10442 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
10443 * ralloc.c: newReg(): when register is REG_SFR then
10444 set address to rIdx,
10445 pic16_allocProcessorRegister(): marks register wasUsed=0
10446 pic16_writeUsedRegs(): added a call to assign processor
10447 registers via pic16_assignFixedRegisters
10449 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10451 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
10452 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
10453 variables in unused register banks. Also the SSEG is placed
10454 wherever there is enough space for it, and IDATA can be anywhere
10455 in internal RAM. For now compile using -Wl-Y[stack_size].
10456 The mem file is different for this option as well, since it
10457 makes no sense of talking about DSEG lenght.
10459 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
10461 * src/SDCClrange.c: fixed bug 869095 that caused segfault

10708 it breaks with bitfields, extern declarations, and gcse analysis.
10709 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
10710 could be assigned through a pointer, so don't complain.

11445 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
11447 * device/lib/_mullong.c: replaced int by short for gcc
11449 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11451 * src/SDCCpeeph.c (notVolatile, notVolatileVariable): handle IFX
11452 and JUMPTABLE iCodes properly now (worked by accident before)
11453 * src/mcs51/gen.c (leftRightUseAcc),
11454 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
11455 iCode properly now. Use getSize instead of nRegs since a & b
11456 aren't part of the nRegs tally.
11458 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
11460 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

11469 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
11470 copied from genNearPointerSet()
11471 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
11472 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
11473 If they pop r0/r1 they must be called in the opposite order than aopOp().
11474 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
11475 (resp. --stack-auto), prepared for --xstack
11477 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11479 * doc/sdccman.lyx: reverted tables to those in cvs 1.64
11481 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>

11486 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
11488 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11489 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
11490 type for bits was changed. It resulted in bit variables becoming
11491 global, which is not permitted in PIC 14 assembly output.
11493 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11495 * doc/sdccman.lyx: various additions and updates. Rearranged sections
11497 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11499 Z80 and MCS51 linkers complaint if a public symbol is defined
11500 in more than one library module:
11504 * as/mcs51/Makefile.in
11506 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11508 A few small changes that speed up the peephole optimizer.
11512 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11514 Try to make the peephole optimizer smarter by maintaining
11515 an association between the assembly source code and the
11516 iCodes that originated them. Put this information to use
11517 with a new peephole rule condition "notVolatile" so that
11518 the rules can be aggressive yet still safe.
11523 * src/mcs51/peeph.def
11525 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11529 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
11530 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
11531 if the left or right operand symbols have the accuse flag set.
11533 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11535 Changed the type of the result of the ! (NOT) operator to char;
11536 previously it returned the same type as the source. This allows
11537 us to eliminate all the genFloatNot functions (all of its target
11538 implementations were very buggy) since !float can use the same
11541 * src/SDCCicode.c (ast2iCode): ! returns char
11542 * src/mcs51/gen.c (genNot, genNotFloat),
11543 * src/ds390/gen.c (genNot, genNotFloat),
11544 * src/z80/gen.c (genNot, genNotFloat),
11545 * src/pic/gen.c (genNot, genNotFloat),
11546 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
11548 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
11550 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11551 1. Interrupt would not compile properly. Ensure PCLATH register is saved
11552 during interrupts. Ensure WSAVE is located at a shared bank address.
11553 2. Fixed page selection in some places
11554 3. Fixed BTFSS/C to where necessary use registers directly and not simply
11555 the registers name strings.
11556 4. Fixed "signed / unsigned compare" compiler warnings.
11557 5. The PIC port manages its own allocation of the general purpose
11558 registers, but makes no attempt to reuse them. As a result when
11559 compiling it soon runs out of general purpose registers. Some
11560 additional code was added to the files pcode.c and device.c to walk
11561 through the function call tree and rename the registers so that they
11571 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
11572 genPlus() & genMinus() when the result is the same as left or right
11574 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

11578 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11580 Made bitfield a distinct type from bit so that bitfields
11581 convert as per ANSI C and bits retain their traditional
11582 boolean style behaviour. Implemented bitfield support in
11590 * src/ds390/gen.c: bit v bitfield split
11591 * src/z80/gen.c: New support for bitfields
11592 * support/regression/tests/bitfields.c: reenabled z80,
11595 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11597 Rules 246.x, 247.x relate to bitfields, the others speed up
11598 access to xdata mapped I/O devices.
11600 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
11602 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11604 Cleaned up genPackBits and genUnpackBits and added two helper
11605 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
11606 for literal assignments in genPackBits (thanks to Frieder for
11612 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11614 Fixed bug #748310 (pointer to function type mishandled when the
11615 function name is omitted). Also fixed a SIGSEGV when a function
11616 attribute (reentrant, etc) is used on a non-function or on a
11617 function but misplaced before the parameter list.
11619 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
11621 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
11622 * support/Util/SDCCerr.h,
11623 * support/Util/SDCCerr.c: Added func attr misuse error msg
11625 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
11627 Fixed bug #787649 by anonymous
11628 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
11629 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
11631 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11633 Fixed numerous bitfield problems.
11635 * src/SDCC.y: More bitfield related error checking

11642 * support/regression/tests/bitfields.c: tests added
11644 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11646 Made the constant following the "interrupt" keyword optional. If
11647 omitted, the function will not automatically be given an entry
11648 in the interrupt vector table (similar to #pragma NOIV, but
11649 less syntacticly kludgy). The interrupt number is also now
11650 range checked. Also fixed a bug in the high order bit example
11657 * support/Util/SDCCerr.c
11658 * support/Util/SDCCerr.h
11661 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

11664 * src/SDCCicode.c (operandOperation): rewritten some ops
11665 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
11666 * src/SDCCsymt.c (computeType): literals are handled the same way as any
11668 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
11669 be re-activated by defining REDUCE_LITERALS)
11670 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
11671 unsigned, but are signed by default
11672 * src/SDCCval.c (constVal): rearranged
11673 * src/SDCCval.c (valMod): preliminary fix
11674 * src/SDCCval.c (valCastLiteral): use TYPE_* types

11712 2003-08-05 Bernhard Held <bernhard AT bernhardheld.de>
11714 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
11715 * src/SDCCval.c (constVal): changed default to signed; hex and octal
11716 constants are unsigned; added recognition of "u" flag for unsigned
11717 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
11718 * src/SDCCval.c (valDiv, valMod): fixed signdness
11719 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
11720 signedness of modulo, left and right shift

12180 added if/endif conditional macros to remove options help
12181 messages from optionsTable when a port is not configured, added
12182 support for the PIc16 port in the ports table, when executing
12183 the compiler with no port specified on command line, a default
12184 port is selected with the new macro DEFAULT_PORT which is
12185 defined in port.h, in setDefaultOptions() linkOptions is removed
12186 from initialization assignment, since now it is a set,
12187 parseCmdLine uses setParseWithComma for linkOptions, in
12188 linkEdit() linkOptions are accessed with new function indexSet()
12189 which returns the i'th item of a set variable. See SDCCset.c, in
12190 linkEdit() when calling buildCmdLine(), added linkOptions as
12191 last argument. Now users can pass arguments to gplink via the
12192 -Wl option, main() uses pic16glue() to glue up pic16 programs

12206 gpasm complaining and test the linkage with gplink, _linkCmd and
12207 _asmCmd changed to be more gplink and gpasm friendly
12208 * src/pic16/peeph.def: peep rule 3 is commented out, since it
12209 produced an error when parsed, peep rule 12 is added to utilize
12210 movff, but it is commented out since the pCode does not support
12211 yet a command with 2 address arguments
12213 2003-05-18 <johan AT balder>
12215 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

13239 * as/mcs51/lkaomf51.c: #include <ctype.h> to remove warnings
13240 * src/pic/main.c (_hasNativeMulFor): outcommented unused variables to remove warnings
13241 * src/pic/pcode.c: outcommented unused variable to remove warnings

13248 2003-01-06 <johan AT balder>
13250 * src/SDCCicode.c: fixed array add
13252 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
13253 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
13254 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
13256 2003-01-04 <johan AT balder>
13258 * src/SDCCval.c (getNelements): fixed the initialized array of structures
13260 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13261 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
13263 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
13264 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
13265 * support/regression/tests/bug-524697.c: fit mem usage into 8032
13267 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
13268 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
13270 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
13271 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
13273 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
13274 * src/mcs51/main.c: removed {bindir}{sep} from aslink
13276 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13278 * in /sdcc/as/mcs51/ changed these files in order to create an
13279 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
13280 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
13281 following files to include the previous two files: aslink.dsp,
13282 Makefile.aslink, Makefile.bcc, and Makefile.in.
13284 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
13285 .adb instead of .cdb
13287 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13289 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
13290 value from option --iram-size.
13292 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13294 * /sdcc/as/mcs51/lklist.c: added boundary check before using
13297 2002-09-18 <wiml AT hhhh.org>
13299 * SDCClrange.h: exposed setFromRange() and setToRange()
13300 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
13301 packRegsForAccUse() (bug 542397)
13302 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
13303 multiple times and emitting the fetch operations more than once
13304 added aopGetUsesAcc() function to allow binary operators to
13305 fetch their operands in the correct order; made genMinus() emit
13306 compact code for X = LITERAL - Y
13308 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13309 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
13310 sprintf() in line 1267.
13312 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13313 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
13316 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13317 Changes to aslink (All the changes are marked with 'JCF'):
13319 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
13322 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
13323 area BSEG. Also moves, if possible, the DATA area down into the internal
13324 ram so more space is available.
13326 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
13329 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
13330 not bytes. Function summary() which creates a memory usage summary
13331 file with extension .mem. Reports of overlaping stack and small stack
13332 size. If the space for the stack is less than 16 bytes aslink trows a
13335 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
13336 the 8051. Option 'y' for memory summary output file.
13338 Changes to sdcc (All the changes are marked with 'JCF'):
13340 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
13342 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
13343 overlaying area for it (uses RegBankUsed[4]).
13345 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
13346 bank zero as used by default. By default aslink locates the stack
13347 (equivalent to --stack-after-data). Pass option 'y' to aslink for
13348 the creation of the .mem file. Delegates the allocation of data area
13349 to aslink (it is not longer 0x30 by default). If --stack-loc passes
13350 the begining of the stack area to aslink.
13352 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
13353 glue() in SDCCglue.c creates an area for it.
13355 2002-09-03 Borut Razem <borut.razem AT siol.net>
13356 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
13357 sdcc/src/pic/glue.c:
13358 introduced atexit() handler for teporay files removal in case of
13359 errors, assertions, ...
13361 2002-08-29 Borut Razem <borut.razem AT siol.net>
13362 * sdcc/support/cpp2/auto-host_vc_in.h:
13363 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
13364 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
13365 Maybe there is a similar problem with BORLANDC? It should be checked!
13367 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
13368 corrected improper use of assert: the assignment to clr variable was done inside the assert.
13369 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
13370 was not executed, and the compiler (cl) launched a warning:
13371 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
13373 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
13374 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
13376 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
13377 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
13379 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
13380 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
13381 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
13382 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
13383 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
13384 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
13385 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
13386 - added Release configuration in VS projects
13387 - review of compiler an linker options
13388 - VC .exe files are generated in bin_vc directory, not to interfere
13389 with binaries generated from other projects (cygwin, mingw, bcc ...)
13391 * sdcc/src/yacc.dsp: added
13393 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
13394 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
13395 and insert the version number definitions from .version
13397 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
13399 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
13400 added - genarate auto-host.h using auto-host_vc_in.h as template
13403 removed from CVS, generated automatically
13405 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
13406 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
13408 2002-08-11 Borut Razem <borut.razem AT siol.net>
13409 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
13411 2002-08-10 Borut Razem <borut.razem AT siol.net>
13412 * src/SDCCmain.c (main):
13413 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
13414 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
13415 The consequence was that some temporary files were not removed.
13418 unification of code in functions tempfilename() and tempfile():
13419 function tempnam() is defined in Visual Studio 6.0 and .NET
13421 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
13423 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
13424 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
13425 - removed compiler command line option /WX: Treats all warnings as errors
13426 - update a list of source files, included into the project
13428 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
13429 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
13430 changed project type to Generic Project so that can be correcly converted to VS.NET project
13432 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
13434 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
13436 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
13438 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
13439 added return 0 statements after assert() to make compiler happy
13441 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
13442 added newline in the def file to keep MSC compiler satisfied
13444 * sdcc/src/z80/gen.c:
13445 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
13446 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
13447 - solved MSC error in function aopDump()
13449 * sdcc_vc.h: define PREFIX as "\\sdcc"
13451 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
13452 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

13455 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
13456 - Rewrote the register banking algorithm.
13457 - Added pCode live-range analysis to registers (for now, only non-used and
13458 singly-used registers optimized away)
13460 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
13462 * 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.

13479 * device/lib/z80/printf.c (sprintf): Added.
13481 * src/z80/ralloc.c (packRegisters): Disabled pack HL use for GB as it's broken.
13483 * src/z80/peeph.def: Added transpose redundent load rule.
13485 * src/z80/main.c: Added force callee saves for jaune.
13487 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
13489 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
13491 2002-03-28 Johan Knol <johan AT balder>
13493 * src/SDCCval.c: fixed bug #532436
13495 2002-03-14 Scott Dattalo <scott AT dattalo.com>
13497 Added "char *Processor" field to the port structure.
13500 Added -p option. Allows port dependent processor to be specified.
13503 Initialized the new field char *Processor field to NULL in all ports
13506 Compiler generated registers for interrupt context saving
13507 were not getting allocated.
13509 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
13512 Fixed left shift. Will promote the left side of a left shift
13513 if a) left shifting more than size of operand or b) when assigned
13514 to something size > size of left side
13516 2002-03-14 Scott Dattalo <scott AT dattalo.com>
13518 tons of changes. Register allocation has been
13519 rewritten. Added customization for the various PICs. Flow
13520 analysis is restructured. ...
13522 * src/pic/device.h:
13525 * src/pic/device.c:
13526 Added. device.c is a PIC port hack to accomodate variations
13529 2002-03-13 Michael Hope <michaelh AT vroom>
13531 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
13533 2002-03-04 johanknol <johanknol AT manik>
13535 * /src/SDCCval.c: fixed
13537 const unsigned char arr[][2] = { { 0, 1 } };
13538 t18.c:1: error: Initializer element is not constant

13624 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
13626 * sdcc/src/SDCCloop.c:
13627 Previous fix was not good. basic blocks that have "break" or "return" are
13628 not really partof a loop , but live ranges used in these blocks should
13629 be live thru the entire loop, so set partOfLoop but don't add them to
13632 2002-02-21 <johan AT FRIJA>
13634 * src/SDCCcse.c: fixed bug #514308
13636 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
13639 Fixed BUG #519583. If a conditional block ended in a return/break
13640 statement inside a loop, it was not being considered part of the loop.
13642 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
13644 2002-02-10 Karl Bongers <karl AT turbobit.com>

13648 with lots of comments and notes.
13650 * device/examples/test2.c:
13651 Fix bug, "red" variable not being initialized(compiler complained).
13653 * device/examples/Makefile, examples/test3.c:
13654 Add Makefile in device/examples folder, compiles test3.c
13655 for use as a multiple module SDCDB test case.
13657 * sim/ucsim/cmd.src/cmdset.cc:
13658 Took out debug printfs in ucsim "next" command.
13660 * sim/ucsim/xa.src:
13661 Karl and Johan start ucsim XA support. Most dissassembly working,
13662 about 75% emulation done(plenty of work remaining).
13664 * sim/ucsim/z80.src:
13665 Add Z80 support to ucsim, add test-ucz80 regression test,
13666 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
13667 Notice z80 compiler fails on examples/test3.c/crc code.
13669 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
13671 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:

13674 * src/ds390/peeph.def:
13675 added a few more peephole optimzations
13677 * src/ds390/main.c:
13678 1) added __builtin_inp & __builtin_outp used to read in data of given length
13679 from a memory mapped port
13680 2) added __builtin_memcmp
