3433 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
3435 Enabled VPATH feature: changed nearly all Makefiles (149 files).
3436 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
3438 One basic decision: e.g. src/clean.mk includes further files. In order
3439 to make this work there are two solutions:
3440 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
3441 run configure on them. This way they can use
3442 'include $(srcdir)/port-clean.mk'
3443 - always include clean.mk by the Makefile at the same level. To avoid
3444 that `make clean` tries to include and build Makefile.dep the
3445 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
3446 implemented, because now even `make uninstall` doesn't create
3447 Makefile.in. clean.mk could be eliminated by pasting it in
3450 * debugger/mcs51/Makefile.in: build own objects from library sources
3451 (SLIB, SDCC) in current directory
3453 * configure, configure.in: renamed --disable-device-lib-build in
3454 --disable-device-lib; added --enable-doc, the required tools are
3455 searched by configure; added result message; the toolchain for the
3456 belonging ports are now only built, if the port is enabled.
3458 * support/regression/*: all output is written in directory gen, because
3459 the fwk and ports directories don't livet in the build tree using vpath
3461 * doc/sdccman.lyx: renamed --disable-device-lib-build to
3462 --disable-device-lib, added --enable-doc, added section VPATH
3464 * sim/ucsim/configure.in,
3465 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
3466 z80 are enabled by default
3468 2006-04-24 Raphael Neider <rneider AT web.de>
3470 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
3471 to config word, "pic14_"-prefixed some extern functions
3472 (pic14_emitConfigWord): emit __config directive(s) if assignment to
3473 config word has been found
3474 * src/pic/device.h: added prototypes
3475 * src/pic/pcode.c: added "pic14_"-prefix where needed
3476 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
3478 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
3480 (pic14emitRegularMap): ignore config words,
3481 (pic14createInterruptVect): moved generating __config directives away
3482 (picglue): have __config directives emitted
3484 2006-04-24 Borut Razem <borut.razem AT siol.net>
3486 * doc/Makefile: sync with nightly build makefile
3488 2006-04-24 Raphael Neider <rneider AT web.de>
3490 * src/pic/pcoderegs.c (OptimizeRegUsage): do not optimize

3716 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
3718 * src/mcs51/gen.c (genCall): fixed bug 1457608
3720 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

3740 interrupts need an interrupt number now if they are made critical),
3741 and enabled nesting of critical functions though not for gbz80
3742 (genCritical, genEndCritical): added functions
3743 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
3744 * src/z80/mappings.i: added "ei" to all mappings

3756 the left operand is shorter than the result (c* = lit-c* + int),
3758 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
3761 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3763 * src/.version: increased version number to 2.5.5
3764 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
3765 linking is done manually in pic16 port's _linkEdit,
3766 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
3767 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
3768 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
3769 allocate asmop as AOP_ACC,
3770 (aopForRemat): added parameter 'bool result' in function declaration,
3771 (pic16_aopGet): return AOP_ACC when accessing WREG,
3772 (pic16_popGetTempReg): minor modification,

3783 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
3784 call to allocReg, not by manually allocating a new one,
3785 (pic16_assignRegisters): now before going through the register
3786 allocating functions mark all registers as free. This eliminates some
3787 side effects resulting from peephole parser done earlier in the backbone
3789 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

3847 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
3848 which dumps before the function entry point a data byte which represents
3849 the number of the local variables used by the specified function, added
3850 'xinst' for initial support for Extended Instruction Support,
3851 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
3852 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
3853 port->fun_prefix anymore (may change later),
3854 (genFunction, genEndFunction): do not store/restore local registers for
3855 _main (this should take care the --main-return command line option in
3857 (genOr): removed some legacy pic-port instructions,
3858 * src/pic16/genarith.c (genAddLit): re-enabled old code because
3859 performing operations with SFR's causes data to be written more than
3860 once to each SFR. Perhaps SFRs should be handled in special cases...
3861 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
3863 * src/pic16/main.c (_process_pragma): stack bound checking did not take
3864 into account for stack starting position,

3866 --extended or -y for Extended Instruction Support,
3867 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
3868 (deassignLRs): *** perhaps the most important change, old 'for' code
3869 (commented out for reference), didn't account for some registers which
3870 were left marked 'not free' after a pointer operation. The change
3871 reduces register usage a lot in some cases
3873 2006-03-04 Borut Razem <borut.razem AT siol.net>
3875 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

6146 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
6147 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
6148 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
6149 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
6150 always available in leading double underscore form. The C99 support is
6151 mostly missing, but it's a start.
6152 * support/regression/tests/bug-227710.c: fixed nonconforming use of
6153 reserved identifier "__data".

6231 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
6233 * device/lib/printf_large.c: removed inline assembly for portability and
6234 readability. Use printf_fast if speed or size are more important.
6235 * src/pic16/gen.c: removed conditions around use of DEBUGpc
6236 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
6238 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
6240 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
6241 prevent compiler warning
6243 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
6245 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
6246 moved to level 0 and declared as static. Also they are explicit
6247 placed in access bank. This was necessery because some times they
6248 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
6249 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
6250 optimizations. Currently only compare to unsigned char is implemented,
6251 * src/pic16/gen.c: added fReturnIdx array,
6252 * (struct resolvedIfx) is moved to gen.h and made public,
6253 * (struct _G): added sregsAlloc and sregsAllocSet fields,
6254 * (aopForSym): added an optimization to directly store in stack of
6255 the operand of a SEND iCode,
6256 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
6257 but as registers instead (AOP_REG) using the fReturnIdx array,
6258 * (pic16_freeAsmop): remove the freed register from the
6259 _G.sregsAlloc field,
6260 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
6261 a compare of 'WREG',
6262 * (pic16_popGetTempRegCond): changed function prototype, now
6263 function takes also a bitVector argument v which holds the current
6264 set of registers that are allocated for stack access by aopForSym,
6265 registers allocated in aopForSym for accessing stack symbols are not
6266 any more part of the functions usedRegs field,
6267 * (genCall): some times aopOp is called for a stack variable to be
6268 send, aopForSym might perform the push, if this is true make sure
6269 that genCall doesn't push the variable twice by testing _G.resDirect,
6270 * (genFunction): changed testing for unspecified interrupt number
6271 from 256 to INTNO_UNSPEC,
6272 * modified selection scheme of frame pointer generation. Previously
6273 if function did use local registers a frame pointer was generated,
6274 now a frame pointer is generated only if function has arguments
6275 (that need PLUSW2 register access), or has stack arguments, or the
6276 compiler is not instructed to omit the frame pointer,
6277 * (genEndFunction): before restoring local registers that were saved
6278 in the function preamble, also restore the registers that *might*
6279 have been allocated for stack access,
6280 * (genRet): removed some old comments,
6281 * (genCmp, the active (RN's) version): added a call to the
6282 pic16_genCmp_special function to perform the compare with a more
6283 robust and optimized way,
6284 * (genInline): a feature has been added in inline code generation,
6285 which allows a wildcard variable substitution when writing inline
6286 assembly. Code is incomplete and experimental therefore undocumented,
6287 * (genCast): changed order of aopOp for result and right to allow
6288 aopForSym to directly load the result if possible,
6289 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
6290 perform an optimized compare on some selected special occasions,
6291 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
6292 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
6293 generate an IVT any more,
6294 * src/pic16/main.c (pic16_optionsTable): added command line option
6296 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
6297 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
6299 * src/pic16/NOTES: Raphael Neider added in list of active developers
6300 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
6301 jumptable_end to prevent bug #,
6302 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
6303 inCond and outCond fields,
6304 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
6305 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
6306 turn off register spilling,
6307 * (packRegsForOneUse): synced with other ports' versions although it
6308 is not used currently,
6309 * (pic16_packRegisters): added an optimization while reading
6310 structure bitfields, some registers may be saved (malloc code is
6311 decreased by 80 bytes)
6313 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
6315 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
6316 left is a bitfield, if yes, then don't optimize assignment. Perhaps
6317 this can be optimized more?
6319 2005-03-10 Raphael Neider <rneider AT web.de>
6321 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
6322 genNearPointerGet): (hopefully) fixed access to bitfields via
6323 pointers (p->bitN = x; and x = p->bitN; failed)
6325 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

6957 Adding support for replacing ljmps with sjmps in jumptables
6958 generated for switch statements. For now you need to set the
6959 environment variable SDCC_SJMP_JUMPTABLE to enable this.
6960 Now 4 algorithms for mcs51 jumptable generation are used:
6961 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
6962 addresses loaded pc-relative for up to 112 cases and stack-pushing
6963 target addresses loaded with offset from dptr for up to 256 cases.

6990 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
6991 to call when a stack overflow occurs,
6992 * (malloc.h): added CVS Id tag,
6993 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
6995 * added libc directory. The current version of LibC contains string
6996 functions, ctype functions and macros and some functions of the
6997 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
6998 be extensively tested in the future. Standard disclaimer here.
6999 Library is not automatically build yet. But one can build it by
7000 invoking 'make' inside the libc directory.
7001 * added ADC library under libio. Preliminary version yet.

7010 * (genUminusFloat): fixed for pic16, ported code from mcs51,
7011 * (pic16_storeForReturn): optimized return of 0,
7012 * (genCmp): experimental code for new genCmp which uses PIC18's
7013 special compare&skip instructions. Initial tests fail some times
7014 with variables grater than 1 byte in size, so new code is disabled,
7015 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
7017 * (genCast): began a fix to optimize the casting of a bit to another
7018 bit, now assigning a bitfield to another bitfield will fail, sorry,
7019 * src/pic16/main.c: disabled the use of lr-support feature,
7020 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

7026 * (isBankInstruction): modified to return 0 for no banking instruction,
7027 and 1 for banking instruction,
7028 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
7029 caused stop processing pCodes after a inline assembly block,
7030 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
7031 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
7032 registers when it shouldn't,
7033 * src/pic16/ralloc.c (allocReg): add preliminary support for
7034 supporting a limited set of temporary registers,
7036 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7038 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,

7041 (loadRegFromAop): recognize CLRH optimization,
7042 (genFunction): optimize RECEIVE iCodes in reentrant functions
7044 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9973 * src/pic/glue (pic14emitRegularMap),
9974 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
9976 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>
9978 * src/pic/pcode.c (PCodeID): commented out left over debug code
9980 2004-01-20 Bernhard Held <bernhard AT bernhardheld.de>
9982 * support/valdiag/tests/overflow.c: added shift tests
9990 * src/pic/pcodepeep.c,
9991 * src/pic/pcoderegs.c,
9993 * src/pic/ralloc.h: applied patch from Slade Rich;
9994 added support for multiple code pages and multiple RAM banks on the
9995 PIC 14 port. The ASM files now no longer simply assume all the
9996 code / RAM are in the same page / bank. This means the linker can
9997 safely allocate code/RAM of separate ASM files to different pages/banks.
9998 * doc/sdccman.lyx: added Slade's tips
9999 * src/mcs51/peeph.def: fixed bug #880768

10011 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
10012 strtof is not part of C89 and isn't included with Mac OS X.
10014 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10016 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

10041 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
10043 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
10044 loaded with the linker search paths (-L arguments) and the libraries
10045 to be linked with the current source (-l arguments). Changes
10046 currently will affect only the pic16 port.
10047 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
10048 include path the port specific paths and port specific libraries,
10049 * gplink command now contains the $3 argument,
10050 * src/pic16/device.h,
10051 * src/pic16/device.c,: structure PIC_device is made public and
10052 renamed to PIC16_device, the same for variable Pics which is renamed
10053 to Pics16. Updated all references to them.
10054 * src/pic16/glue.c (pic16glue): corrected bug with code
10055 initialization which bypassed the variable initializations block.
10057 * device/lib/pic16/Makefile.rules: removed --penable-stack from

10065 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
10067 Documenting changes from previous commits.
10068 * configure.in (version 1.56),
10069 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
10070 when generating output files to configure the pic16 library,
10071 but now I've commented it out, since gputils aren't installed in the
10072 SF compile farm, so library won't compile
10074 * device/lib/Makefile.in (version 1.56): initially I've added in
10075 target 'all' the prerequestive 'model-pic16' so it compiled the
10076 pic16 library, but now I've commented it out for the same reasons
10078 * added targets 'model-pic16' and 'objects-pic16' to compile the
10080 * added target 'port-specific-objects-pic16' to handle the
10081 generated libraries and copy them into the build/ directory
10082 * added target 'clean-intermediate-pic16' to clean intermediate
10083 files into pic16 directory
10084 * in target 'installdirs' added line to create directory pic16 in
10085 the installation path
10087 * device/include/Makefile.in (version 1.11): in target 'install'
10088 added lines to copy all header files to installation path,
10089 * in target 'installdirs' added line create directory for pic16
10090 headers in the installation path
10092 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

10103 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10105 * src/z80/main.c (_parseOptions): fixed the portmode= command line
10106 option so that it actually works. Made it specific to the z80, since
10107 the gbz80 doesn't have these kinds of I/O ports.
10109 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10111 * device/include/z180.h,

10133 Mainly changes to support compilation of the device libraries
10134 * src/pic16/device.c: stack is allocated via symbol and not
10135 via literal number. The symbol is placed in the corresponding
10136 position of the data ram
10137 * (pic16_dump_section): relocatable and absolute uninitialized
10138 data are now emitted in sorted order to reduce section naming,
10139 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
10140 weren't marked as being in the access bank,
10142 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
10144 Added portion of GNU PIC Library under the directory
10145 device/include/pic16 and device/lib/pic16. These files
10146 contain the declarations of SFRs for the PIC18Fxx2 devices.
10147 The directory is initialized via configure from toplevel.
10149 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
10151 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
10152 the spilllocations to be compared correctly
10154 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
10156 * src/SDCCast.c (decorateType): fixed bug introduced today
10158 2004-01-12 Borut Razem <borut.razem AT siol.net>

10176 * doc/sdccman.lyx: Moved and added some sections, small changes
10177 all over. Telling LaTeX to be less strict with word spacing
10178 to better keep the right margin. Changed some notes about
10179 maintainance of the ports in section 3.2.1 - is it OK like this?
10181 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

10218 UPPER for immediate operands,
10219 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
10221 * src/pic16/peeph.def: all peepholes with movff are commented out,
10222 because there is a problem in the pcode peep optimizer,
10223 * src/pic16/ralloc.c: the register allocator can now reuse local
10224 function symbols for another function. This saves register usage.
10225 * src/pic16/ralloc.h: added flag isLocal in structure regs,
10227 Added file src/pic16/NOTES with information about program writing on
10228 the current port version.

10232 * src/mcs51/peephole.def: added peepholes 177.c,d (redundant moves)
10233 and peephole 252 (array access)
10235 2004-01-09 Borut Razem <borut.razem AT siol.net>
10237 * src/SDCCmain.c : fixed #872250: -l command line defined library

10257 gen51Code): more efficient parameter receive for --model-large
10260 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10262 * src/ds390/main.c,
10263 * src/z80/main.c: added missed needLinkerScript flags (more than
10264 one port structure defined in these file)
10265 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed
10268 2004-01-08 Vangelis Rokas <vrokas AT otenet.gr>
10270 * src/SDCCmain.c: removed various references to DEFAULT_PORT
10271 * src/port.h: added flag needLinkerScript in port->linker

10285 override default uninitialized data segment definition for
10286 devices only with SHAREBANK memory (reported from Erik Epetrich)
10287 * (pic14emitOverlay): modified to emit a commented overlay segment
10288 directive when no overlay data exist
10289 * (picglue): modified to emit uninitialized data segment
10290 according to udata_section_name
10291 * src/pic/main.c (_pic14_parseOptions): added command line
10292 options --udata-section-name=[name] to override default
10293 udata definition name

10298 changed size of fptr from 2 to 3 in port structure
10300 2004-01-07 Borut Razem <borut.razem AT siol.net>
10302 * support/scripts/sdcc.nsi: update PATH
10303 * support/scripts/sdcc.ico: craeted

10338 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10340 A python script to validate compiler diagnostic messages. It can be
10341 used to verify that sdcc complains about bad c source code and
10342 gives a good location of the error.
10343 * support/valdiag/Makefile,
10344 * support/valdiag/valdiag.py,
10345 * support/valdiag/tests/*
10347 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10358 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
10360 * src/common.h: added ifndef/define/endif macros
10361 around the header file.
10362 Bug reported from Jesus Calvino-Fraga
10364 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
10366 * sdcc.spec: updated
10367 * device/include/Makefile.in: don't install CVS directories

10375 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
10377 PIC16 port related changes:
10378 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
10379 added variable stackPos,
10381 * gen.c: genCall, assignResultValue: added support for
10382 pushing/retrieving function parameters to/from stack,
10383 genFunction,genEndFunction: setup stack frame for the
10384 generated function,
10385 genAddrOf: will be changed according to bug 863624
10387 * added files genutils.c and genutils.h which contain gen*
10388 debugged and optimised functions extracted from gen.c
10390 * glue.c: added variable 'externs' which holds extern symbols,
10391 pic16emitRegularMap: is modified to properly handle relocatable
10392 symbols under the new scheme,
10393 pic16createInterruptVect: is modified
10394 pic16printPublics: is modified to emit 'global' assembler directives,
10395 added pic16_printExterns to print extern symbols,
10396 pic16glue: initializes stack/frame pointer in the beginning of
10397 the assembly output. Temporary hack, will be corrected later,
10398 because gplink yet does not support stack and SDCC does not
10399 yet support a type of crt0.o object to create the final binary.
10401 * Removed many lines that contain 8051 legacy code.
10402 * The code is finally placed under a 'code' directive.
10403 * Added port specific options.
10405 * _process_pragma: simplified since now we do not need *special*
10406 include file to define SFR registers. But a separate header
10407 will be needed. This will be developed later.
10408 * _pic16_parseOptions: added, parses port specific options:
10409 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
10410 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
10411 --preplace-udata-with=
10413 * _pic16_setDefaultOptions: modified to initialize section names,
10414 but hack is temporarly out of order since it needs improvement.
10415 * _pic16_genAssemblerPreamble: configuration words are emitted by
10416 their address instead of their name. This part is incomplete and
10417 supports only the 18Fxx2 devices. Other devices will emit an error
10418 during assembly since they do not contain the same set of config
10420 * _pic16_genIVT: is modified,
10422 * pcode.c: added definitions for some hardware registers that are needed
10424 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
10425 All PCI entries are updated. Now LFSR is supported.
10426 * Removed pic16_pciTRIS is mentioned by mdubuc in source
10427 * added pic16_newpCodeOpLit2 to support instructions with
10428 two literal arguments
10429 * pic16_pCode2str: corrected code that emits assembler instructions
10430 with two literal operands and those that have an access bit modifier
10431 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
10432 this fixes a bug which caused some labels to be lost, when an
10433 assembler directive was added, i.e. banksel,
10434 * pic16_FixRegisterBanking: improved logic that causes the insertion
10436 * InlineFunction: functions that are called once, are not any more
10437 inlined. This can be a port option in the future,
10439 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
10441 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
10442 hold the corresponding uninitialized symbols,
10443 * pic16_allocProcessorRegister: registers have explicit marked the
10445 * pic16_allocInternalRegister: registers are explicit marked as
10447 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
10448 processing list, so bit registers were lost,
10451 * ralloc.h: added field 'accessBank' and original symbol operand
10452 in register definition,
10453 * removed the field isMapped from register definition,
10455 ** Several functions have been removed from various sources:
10456 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
10457 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
10458 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
10459 pic16_assignRelocatableRegisters
10461 ** others have been introduced:
10462 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
10463 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
10465 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
10467 * support/scripts/inc2h.pl: changed definition of BIT_AT
10468 to emit 'sbit at' instead of 'bit at'. This was a request.
10470 PIC16 port related preliminary changes:
10471 * gen.c: prefixed function popRegFromString with
10472 pic16_ and all references to it corrected
10473 * pcode.c: all pic16_pc_* hardware registers prefixed
10474 with underscore (_),
10475 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
10476 * ralloc.c: newReg(): when register is REG_SFR then
10477 set address to rIdx,
10478 pic16_allocProcessorRegister(): marks register wasUsed=0
10479 pic16_writeUsedRegs(): added a call to assign processor
10480 registers via pic16_assignFixedRegisters
10482 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10484 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
10485 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
10486 variables in unused register banks. Also the SSEG is placed
10487 wherever there is enough space for it, and IDATA can be anywhere
10488 in internal RAM. For now compile using -Wl-Y[stack_size].
10489 The mem file is different for this option as well, since it
10490 makes no sense of talking about DSEG lenght.
10492 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
10494 * src/SDCClrange.c: fixed bug 869095 that caused segfault

10741 it breaks with bitfields, extern declarations, and gcse analysis.
10742 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
10743 could be assigned through a pointer, so don't complain.

11384 support for standard C idiom of memory mapped variables; for
11385 example, *((xdata int*)0x1234) = 1 is now internally equivalent
11386 to xdata int at 0x1234 tempvar = 1.

11485 and JUMPTABLE iCodes properly now (worked by accident before)
11486 * src/mcs51/gen.c (leftRightUseAcc),
11487 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
11488 iCode properly now. Use getSize instead of nRegs since a & b
11489 aren't part of the nRegs tally.
11491 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
11493 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

11503 copied from genNearPointerSet()
11504 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
11505 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
11506 If they pop r0/r1 they must be called in the opposite order than aopOp().
11507 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
11508 (resp. --stack-auto), prepared for --xstack
11510 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

11519 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
11521 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11522 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
11523 type for bits was changed. It resulted in bit variables becoming
11524 global, which is not permitted in PIC 14 assembly output.
11526 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11528 * doc/sdccman.lyx: various additions and updates. Rearranged sections
11530 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11532 Z80 and MCS51 linkers complaint if a public symbol is defined

11541 A few small changes that speed up the peephole optimizer.
11545 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11547 Try to make the peephole optimizer smarter by maintaining
11548 an association between the assembly source code and the
11549 iCodes that originated them. Put this information to use
11550 with a new peephole rule condition "notVolatile" so that
11551 the rules can be aggressive yet still safe.
11556 * src/mcs51/peeph.def
11558 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11562 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
11563 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
11564 if the left or right operand symbols have the accuse flag set.
11566 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11568 Changed the type of the result of the ! (NOT) operator to char;
11569 previously it returned the same type as the source. This allows
11570 us to eliminate all the genFloatNot functions (all of its target
11571 implementations were very buggy) since !float can use the same
11574 * src/SDCCicode.c (ast2iCode): ! returns char

11583 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11584 1. Interrupt would not compile properly. Ensure PCLATH register is saved
11585 during interrupts. Ensure WSAVE is located at a shared bank address.
11586 2. Fixed page selection in some places
11587 3. Fixed BTFSS/C to where necessary use registers directly and not simply
11588 the registers name strings.
11589 4. Fixed "signed / unsigned compare" compiler warnings.
11590 5. The PIC port manages its own allocation of the general purpose
11591 registers, but makes no attempt to reuse them. As a result when
11592 compiling it soon runs out of general purpose registers. Some
11593 additional code was added to the files pcode.c and device.c to walk
11594 through the function call tree and rename the registers so that they
11604 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
11605 genPlus() & genMinus() when the result is the same as left or right
11607 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

11611 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11613 Made bitfield a distinct type from bit so that bitfields
11614 convert as per ANSI C and bits retain their traditional
11615 boolean style behaviour. Implemented bitfield support in
11623 * src/ds390/gen.c: bit v bitfield split
11624 * src/z80/gen.c: New support for bitfields
11625 * support/regression/tests/bitfields.c: reenabled z80,
11628 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11630 Rules 246.x, 247.x relate to bitfields, the others speed up
11631 access to xdata mapped I/O devices.
11633 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
11635 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11637 Cleaned up genPackBits and genUnpackBits and added two helper
11638 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
11639 for literal assignments in genPackBits (thanks to Frieder for
11645 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11647 Fixed bug #748310 (pointer to function type mishandled when the
11648 function name is omitted). Also fixed a SIGSEGV when a function
11649 attribute (reentrant, etc) is used on a non-function or on a
11650 function but misplaced before the parameter list.
11652 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
11654 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
11655 * support/Util/SDCCerr.h,
11656 * support/Util/SDCCerr.c: Added func attr misuse error msg
11658 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
11660 Fixed bug #787649 by anonymous
11661 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
11662 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
11664 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11666 Fixed numerous bitfield problems.

11677 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11679 Made the constant following the "interrupt" keyword optional. If
11680 omitted, the function will not automatically be given an entry
11681 in the interrupt vector table (similar to #pragma NOIV, but
11682 less syntacticly kludgy). The interrupt number is also now
11683 range checked. Also fixed a bug in the high order bit example

11697 * src/SDCCicode.c (operandOperation): rewritten some ops
11698 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
11699 * src/SDCCsymt.c (computeType): literals are handled the same way as any
11701 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
11702 be re-activated by defining REDUCE_LITERALS)
11703 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
11704 unsigned, but are signed by default
11705 * src/SDCCval.c (constVal): rearranged
11706 * src/SDCCval.c (valMod): preliminary fix
11707 * src/SDCCval.c (valCastLiteral): use TYPE_* types

11747 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
11748 * src/SDCCval.c (constVal): changed default to signed; hex and octal
11749 constants are unsigned; added recognition of "u" flag for unsigned
11750 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
11751 * src/SDCCval.c (valDiv, valMod): fixed signdness

12213 added if/endif conditional macros to remove options help
12214 messages from optionsTable when a port is not configured, added
12215 support for the PIc16 port in the ports table, when executing
12216 the compiler with no port specified on command line, a default
12217 port is selected with the new macro DEFAULT_PORT which is
12218 defined in port.h, in setDefaultOptions() linkOptions is removed
12219 from initialization assignment, since now it is a set,
12220 parseCmdLine uses setParseWithComma for linkOptions, in
12221 linkEdit() linkOptions are accessed with new function indexSet()
12222 which returns the i'th item of a set variable. See SDCCset.c, in
12223 linkEdit() when calling buildCmdLine(), added linkOptions as
12224 last argument. Now users can pass arguments to gplink via the
12225 -Wl option, main() uses pic16glue() to glue up pic16 programs

12239 gpasm complaining and test the linkage with gplink, _linkCmd and
12240 _asmCmd changed to be more gplink and gpasm friendly
12241 * src/pic16/peeph.def: peep rule 3 is commented out, since it
12242 produced an error when parsed, peep rule 12 is added to utilize
12243 movff, but it is commented out since the pCode does not support
12244 yet a command with 2 address arguments
12246 2003-05-18 <johan AT balder>
12248 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

13270 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
13271 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings
13272 * as/mcs51/lkaomf51.c: #include <ctype.h> to remove warnings
13273 * src/pic/main.c (_hasNativeMulFor): outcommented unused variables to remove warnings

13281 2003-01-06 <johan AT balder>
13283 * src/SDCCicode.c: fixed array add
13285 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
13286 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
13287 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
13289 2003-01-04 <johan AT balder>

13293 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13294 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
13296 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
13297 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

13303 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
13304 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
13306 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
13307 * src/mcs51/main.c: removed {bindir}{sep} from aslink
13309 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13311 * in /sdcc/as/mcs51/ changed these files in order to create an
13312 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
13313 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
13314 following files to include the previous two files: aslink.dsp,
13315 Makefile.aslink, Makefile.bcc, and Makefile.in.
13317 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
13318 .adb instead of .cdb
13320 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13322 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
13323 value from option --iram-size.
13325 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13327 * /sdcc/as/mcs51/lklist.c: added boundary check before using
13330 2002-09-18 <wiml AT hhhh.org>
13332 * SDCClrange.h: exposed setFromRange() and setToRange()
13333 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
13334 packRegsForAccUse() (bug 542397)
13335 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
13336 multiple times and emitting the fetch operations more than once
13337 added aopGetUsesAcc() function to allow binary operators to
13338 fetch their operands in the correct order; made genMinus() emit
13339 compact code for X = LITERAL - Y
13341 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13342 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
13343 sprintf() in line 1267.
13345 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13346 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
13349 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13350 Changes to aslink (All the changes are marked with 'JCF'):
13352 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
13355 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
13356 area BSEG. Also moves, if possible, the DATA area down into the internal
13357 ram so more space is available.
13359 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
13362 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
13363 not bytes. Function summary() which creates a memory usage summary
13364 file with extension .mem. Reports of overlaping stack and small stack
13365 size. If the space for the stack is less than 16 bytes aslink trows a
13368 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
13369 the 8051. Option 'y' for memory summary output file.
13371 Changes to sdcc (All the changes are marked with 'JCF'):
13373 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
13375 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
13376 overlaying area for it (uses RegBankUsed[4]).
13378 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
13379 bank zero as used by default. By default aslink locates the stack
13380 (equivalent to --stack-after-data). Pass option 'y' to aslink for
13381 the creation of the .mem file. Delegates the allocation of data area
13382 to aslink (it is not longer 0x30 by default). If --stack-loc passes
13383 the begining of the stack area to aslink.
13385 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
13386 glue() in SDCCglue.c creates an area for it.
13388 2002-09-03 Borut Razem <borut.razem AT siol.net>
13389 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
13390 sdcc/src/pic/glue.c:
13391 introduced atexit() handler for teporay files removal in case of
13392 errors, assertions, ...
13394 2002-08-29 Borut Razem <borut.razem AT siol.net>
13395 * sdcc/support/cpp2/auto-host_vc_in.h:
13396 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
13397 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
13398 Maybe there is a similar problem with BORLANDC? It should be checked!
13400 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
13401 corrected improper use of assert: the assignment to clr variable was done inside the assert.
13402 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
13403 was not executed, and the compiler (cl) launched a warning:
13404 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
13406 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
13407 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
13409 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
13410 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
13412 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
13413 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
13414 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
13415 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
13416 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
13417 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
13418 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
13419 - added Release configuration in VS projects
13420 - review of compiler an linker options
13421 - VC .exe files are generated in bin_vc directory, not to interfere
13422 with binaries generated from other projects (cygwin, mingw, bcc ...)
13424 * sdcc/src/yacc.dsp: added
13426 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
13427 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
13428 and insert the version number definitions from .version
13430 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
13432 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
13433 added - genarate auto-host.h using auto-host_vc_in.h as template
13436 removed from CVS, generated automatically
13438 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
13439 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
13441 2002-08-11 Borut Razem <borut.razem AT siol.net>
13442 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
13444 2002-08-10 Borut Razem <borut.razem AT siol.net>
13445 * src/SDCCmain.c (main):
13446 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
13447 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
13448 The consequence was that some temporary files were not removed.
13451 unification of code in functions tempfilename() and tempfile():
13452 function tempnam() is defined in Visual Studio 6.0 and .NET
13454 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
13456 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
13457 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
13458 - removed compiler command line option /WX: Treats all warnings as errors
13459 - update a list of source files, included into the project
13461 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
13462 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
13463 changed project type to Generic Project so that can be correcly converted to VS.NET project
13465 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
13467 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
13469 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
13471 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
13472 added return 0 statements after assert() to make compiler happy
13474 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
13475 added newline in the def file to keep MSC compiler satisfied
13477 * sdcc/src/z80/gen.c:
13478 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
13479 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
13480 - solved MSC error in function aopDump()
13482 * sdcc_vc.h: define PREFIX as "\\sdcc"
13484 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
13485 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
13487 2002-06-22 Scott Dattalo <scott AT dattalo.com>
13488 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
13489 - Rewrote the register banking algorithm.
13490 - Added pCode live-range analysis to registers (for now, only non-used and
13491 singly-used registers optimized away)
13493 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
13495 * 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.

13512 * device/lib/z80/printf.c (sprintf): Added.
13514 * src/z80/ralloc.c (packRegisters): Disabled pack HL use for GB as it's broken.
13516 * src/z80/peeph.def: Added transpose redundent load rule.
13518 * src/z80/main.c: Added force callee saves for jaune.
13520 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
13522 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
13524 2002-03-28 Johan Knol <johan AT balder>
13526 * src/SDCCval.c: fixed bug #532436
13528 2002-03-14 Scott Dattalo <scott AT dattalo.com>
13530 Added "char *Processor" field to the port structure.
13533 Added -p option. Allows port dependent processor to be specified.
13536 Initialized the new field char *Processor field to NULL in all ports
13539 Compiler generated registers for interrupt context saving
13540 were not getting allocated.
13542 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
13545 Fixed left shift. Will promote the left side of a left shift
13546 if a) left shifting more than size of operand or b) when assigned
13547 to something size > size of left side
13549 2002-03-14 Scott Dattalo <scott AT dattalo.com>
13551 tons of changes. Register allocation has been
13552 rewritten. Added customization for the various PICs. Flow
13553 analysis is restructured. ...
13555 * src/pic/device.h:
13558 * src/pic/device.c:
13559 Added. device.c is a PIC port hack to accomodate variations
13562 2002-03-13 Michael Hope <michaelh AT vroom>
13564 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
13566 2002-03-04 johanknol <johanknol AT manik>
13568 * /src/SDCCval.c: fixed
13570 const unsigned char arr[][2] = { { 0, 1 } };

13657 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
13659 * sdcc/src/SDCCloop.c:
13660 Previous fix was not good. basic blocks that have "break" or "return" are
13661 not really partof a loop , but live ranges used in these blocks should
13662 be live thru the entire loop, so set partOfLoop but don't add them to
13665 2002-02-21 <johan AT FRIJA>
13667 * src/SDCCcse.c: fixed bug #514308
13669 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
13672 Fixed BUG #519583. If a conditional block ended in a return/break
13673 statement inside a loop, it was not being considered part of the loop.
13675 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
13677 2002-02-10 Karl Bongers <karl AT turbobit.com>

13681 with lots of comments and notes.
13683 * device/examples/test2.c:
13684 Fix bug, "red" variable not being initialized(compiler complained).
13686 * device/examples/Makefile, examples/test3.c:
13687 Add Makefile in device/examples folder, compiles test3.c
13688 for use as a multiple module SDCDB test case.
13690 * sim/ucsim/cmd.src/cmdset.cc:
13691 Took out debug printfs in ucsim "next" command.
