2477 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2479 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2480 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2482 One basic decision: e.g. src/clean.mk includes further files. In order
2483 to make this work there are two solutions:
2484 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2485 run configure on them. This way they can use
2486 'include $(srcdir)/port-clean.mk'
2487 - always include clean.mk by the Makefile at the same level. To avoid
2488 that `make clean` tries to include and build Makefile.dep the
2489 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2490 implemented, because now even `make uninstall` doesn't create
2491 Makefile.in. clean.mk could be eliminated by pasting it in
2494 * debugger/mcs51/Makefile.in: build own objects from library sources
2495 (SLIB, SDCC) in current directory
2497 * configure, configure.in: renamed --disable-device-lib-build in
2498 --disable-device-lib; added --enable-doc, the required tools are
2499 searched by configure; added result message; the toolchain for the
2500 belonging ports are now only built, if the port is enabled.
2502 * support/regression/*: all output is written in directory gen, because
2503 the fwk and ports directories don't livet in the build tree using vpath
2505 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2506 --disable-device-lib, added --enable-doc, added section VPATH
2508 * sim/ucsim/configure.in,
2509 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2510 z80 are enabled by default
2512 2006-04-24 Raphael Neider <rneider AT web.de>
2514 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2515 to config word, "pic14_"-prefixed some extern functions
2516 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2517 config word has been found
2518 * src/pic/device.h: added prototypes
2519 * src/pic/pcode.c: added "pic14_"-prefix where needed
2520 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
2522 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

2525 (pic14createInterruptVect): moved generating __config directives away

2535 registers that have not been assigned proper liveranges,
2536 fixes #1469504 and #1474602,
2537 (pCodeRegOptimizeRegUsage): fixed typo in comment
2539 2006-04-24 Borut Razem <borut.razem AT siol.net>
2541 * device/examples/main8051.c: deleted - it was removed from CVS
2542 24.mar.2000 and after that modified 18.feb.2001, so it reappered
2543 after the transition to Subversion
2544 * src/SDCCalloc.h: deleted - it was removed from CVS
2545 3.feb.2001 and after that modified 18.feb.2001, so it reappered

2783 implemented patch 1120823 Thanks to Willy De la Court (normal
2784 interrupts need an interrupt number now if they are made critical),
2785 and enabled nesting of critical functions though not for gbz80
2786 (genCritical, genEndCritical): added functions
2787 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
2788 * src/z80/mappings.i: added "ei" to all mappings

2800 the left operand is shorter than the result (c* = lit-c* + int),
2802 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
2805 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2807 * src/.version: increased version number to 2.5.5
2808 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
2809 linking is done manually in pic16 port's _linkEdit,
2810 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
2811 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
2812 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
2813 allocate asmop as AOP_ACC,
2814 (aopForRemat): added parameter 'bool result' in function declaration,
2815 (pic16_aopGet): return AOP_ACC when accessing WREG,
2816 (pic16_popGetTempReg): minor modification,

2827 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2828 call to allocReg, not by manually allocating a new one,
2829 (pic16_assignRegisters): now before going through the register
2830 allocating functions mark all registers as free. This eliminates some
2831 side effects resulting from peephole parser done earlier in the backbone
2833 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

2891 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
2892 which dumps before the function entry point a data byte which represents
2893 the number of the local variables used by the specified function, added
2894 'xinst' for initial support for Extended Instruction Support,
2895 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2896 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2897 port->fun_prefix anymore (may change later),
2898 (genFunction, genEndFunction): do not store/restore local registers for
2899 _main (this should take care the --main-return command line option in
2901 (genOr): removed some legacy pic-port instructions,
2902 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2903 performing operations with SFR's causes data to be written more than
2904 once to each SFR. Perhaps SFRs should be handled in special cases...
2905 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2907 * src/pic16/main.c (_process_pragma): stack bound checking did not take
2908 into account for stack starting position,

2910 --extended or -y for Extended Instruction Support,
2911 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
2912 (deassignLRs): *** perhaps the most important change, old 'for' code
2913 (commented out for reference), didn't account for some registers which
2914 were left marked 'not free' after a pointer operation. The change
2915 reduces register usage a lot in some cases

5184 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5186 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),

5190 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
5191 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
5192 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
5193 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
5194 always available in leading double underscore form. The C99 support is
5195 mostly missing, but it's a start.
5196 * support/regression/tests/bug-227710.c: fixed nonconforming use of
5197 reserved identifier "__data".
5199 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

5243 immedDom() returning wrong block; probably fixes bug #1160833)
5245 2005-03-20 Borut Razem <borut.razem AT siol.net>
5247 * support/scripts/inc2h.pl: WIN32 port

5251 * device/lib/makefile.in: added abs.c and labs.c
5253 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
5255 * device/include/stdint.h: added
5256 * device/lib/abs.c: added

5275 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
5277 * device/lib/printf_large.c: removed inline assembly for portability and
5278 readability. Use printf_fast if speed or size are more important.
5279 * src/pic16/gen.c: removed conditions around use of DEBUGpc
5280 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
5282 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
5284 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
5285 prevent compiler warning
5287 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
5289 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
5290 moved to level 0 and declared as static. Also they are explicit
5291 placed in access bank. This was necessery because some times they
5292 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
5293 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
5294 optimizations. Currently only compare to unsigned char is implemented,
5295 * src/pic16/gen.c: added fReturnIdx array,
5296 * (struct resolvedIfx) is moved to gen.h and made public,
5297 * (struct _G): added sregsAlloc and sregsAllocSet fields,
5298 * (aopForSym): added an optimization to directly store in stack of
5299 the operand of a SEND iCode,
5300 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
5301 but as registers instead (AOP_REG) using the fReturnIdx array,
5302 * (pic16_freeAsmop): remove the freed register from the
5303 _G.sregsAlloc field,
5304 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
5305 a compare of 'WREG',
5306 * (pic16_popGetTempRegCond): changed function prototype, now
5307 function takes also a bitVector argument v which holds the current
5308 set of registers that are allocated for stack access by aopForSym,
5309 registers allocated in aopForSym for accessing stack symbols are not
5310 any more part of the functions usedRegs field,
5311 * (genCall): some times aopOp is called for a stack variable to be
5312 send, aopForSym might perform the push, if this is true make sure
5313 that genCall doesn't push the variable twice by testing _G.resDirect,
5314 * (genFunction): changed testing for unspecified interrupt number
5315 from 256 to INTNO_UNSPEC,
5316 * modified selection scheme of frame pointer generation. Previously
5317 if function did use local registers a frame pointer was generated,
5318 now a frame pointer is generated only if function has arguments
5319 (that need PLUSW2 register access), or has stack arguments, or the
5320 compiler is not instructed to omit the frame pointer,
5321 * (genEndFunction): before restoring local registers that were saved
5322 in the function preamble, also restore the registers that *might*
5323 have been allocated for stack access,
5324 * (genRet): removed some old comments,
5325 * (genCmp, the active (RN's) version): added a call to the
5326 pic16_genCmp_special function to perform the compare with a more
5327 robust and optimized way,
5328 * (genInline): a feature has been added in inline code generation,
5329 which allows a wildcard variable substitution when writing inline
5330 assembly. Code is incomplete and experimental therefore undocumented,
5331 * (genCast): changed order of aopOp for result and right to allow
5332 aopForSym to directly load the result if possible,
5333 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
5334 perform an optimized compare on some selected special occasions,
5335 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
5336 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
5337 generate an IVT any more,
5338 * src/pic16/main.c (pic16_optionsTable): added command line option
5340 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
5341 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
5343 * src/pic16/NOTES: Raphael Neider added in list of active developers
5344 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
5345 jumptable_end to prevent bug #,
5346 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
5347 inCond and outCond fields,
5348 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
5349 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
5350 turn off register spilling,
5351 * (packRegsForOneUse): synced with other ports' versions although it
5352 is not used currently,
5353 * (pic16_packRegisters): added an optimization while reading
5354 structure bitfields, some registers may be saved (malloc code is
5355 decreased by 80 bytes)
5357 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
5359 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
5360 left is a bitfield, if yes, then don't optimize assignment. Perhaps
5361 this can be optimized more?
5363 2005-03-10 Raphael Neider <rneider AT web.de>
5365 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
5366 genNearPointerGet): (hopefully) fixed access to bitfields via
5367 pointers (p->bitN = x; and x = p->bitN; failed)
5369 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

5412 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
5413 to keep the correct label reference count when adding/removing references
5414 to labels. A peephole file using this is appended to patch #1144962.

5546 * src/pic16/main.c (_process_pragma): fixed another malloc bug
5547 (sizeof(sectNames) changed to sizeof(sectName))
5548 Both patches fix segfaults under MinGW.

5555 of (byte sized) temporaries (assign them to WREG for now)
5556 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
5557 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
5558 this might fix SIGSEGVs on MinGW...
5559 * src/SDCCopt.c (killDeadCode): restored original behaviour
5560 (volatile operands might get thrown away though)
5562 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
5564 * src/pic16/gen.c: fixed bug #1106975,

5999 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6001 Adding support for replacing ljmps with sjmps in jumptables
6002 generated for switch statements. For now you need to set the
6003 environment variable SDCC_SJMP_JUMPTABLE to enable this.
6004 Now 4 algorithms for mcs51 jumptable generation are used:
6005 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
6006 addresses loaded pc-relative for up to 112 cases and stack-pushing
6007 target addresses loaded with offset from dptr for up to 256 cases.
6009 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
6010 * src/mcs51/main.c: adapted constants for switch table generation
6011 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

6031 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
6033 Large cummulative patch for pic16 port.
6034 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
6035 to call when a stack overflow occurs,
6036 * (malloc.h): added CVS Id tag,
6037 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
6039 * added libc directory. The current version of LibC contains string
6040 functions, ctype functions and macros and some functions of the
6041 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
6042 be extensively tested in the future. Standard disclaimer here.
6043 Library is not automatically build yet. But one can build it by
6044 invoking 'make' inside the libc directory.
6045 * added ADC library under libio. Preliminary version yet.
6047 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
6048 * src/pic16/gen.c (aopForRemat): asmop size is filled by
6049 aopForRemat() now and not by pic16_aopOp(),
6050 * (pic16_popGetTempReg): removed warning messgae when allocating
6051 temporary registers, its a buggy feature and will be removed,
6052 * (pic16_popGet): set register instance field in AOP_CRY,
6053 * (pic16_outBitC): fixed for results in size greater than 1,
6054 * (genUminusFloat): fixed for pic16, ported code from mcs51,
6055 * (pic16_storeForReturn): optimized return of 0,
6056 * (genCmp): experimental code for new genCmp which uses PIC18's
6057 special compare&skip instructions. Initial tests fail some times
6058 with variables grater than 1 byte in size, so new code is disabled,
6059 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
6061 * (genCast): began a fix to optimize the casting of a bit to another
6062 bit, now assigning a bitfield to another bitfield will fail, sorry,
6063 * src/pic16/main.c: disabled the use of lr-support feature,
6064 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
6065 * added some function prototypes, added function _debugf prototype,
6066 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
6067 bits with offset (case PO_GPR_BIT),
6068 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
6070 * (isBankInstruction): modified to return 0 for no banking instruction,
6071 and 1 for banking instruction,
6072 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
6073 caused stop processing pCodes after a inline assembly block,
6074 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
6075 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
6076 registers when it shouldn't,
6077 * src/pic16/ralloc.c (allocReg): add preliminary support for
6078 supporting a limited set of temporary registers,
6080 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6082 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
6083 genDataPointerSet): ensure assignments always copy in MSB to LSB
6085 (loadRegFromAop): recognize CLRH optimization,
6086 (genFunction): optimize RECEIVE iCodes in reentrant functions
6088 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6090 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
6091 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
6093 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

6100 * device/lib/_gptrgetc.c (_gptrgetc),
6101 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
6102 instead of sjmp to ret
6103 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
6104 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
6106 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

9088 loaded with the linker search paths (-L arguments) and the libraries
9089 to be linked with the current source (-l arguments). Changes
9090 currently will affect only the pic16 port.
9091 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
9092 include path the port specific paths and port specific libraries,
9093 * gplink command now contains the $3 argument,
9094 * src/pic16/device.h,
9095 * src/pic16/device.c,: structure PIC_device is made public and
9096 renamed to PIC16_device, the same for variable Pics which is renamed
9097 to Pics16. Updated all references to them.
9098 * src/pic16/glue.c (pic16glue): corrected bug with code
9099 initialization which bypassed the variable initializations block.
9101 * device/lib/pic16/Makefile.rules: removed --penable-stack from
9102 COMPILE_FLAGS and added the --nostdinc option
9104 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9106 * device/include/mc68hc908jb8.h: Register defs for another member
9107 of the hc08 family. Contributed by Bjorn Bringert - thanks!
9109 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
9111 Documenting changes from previous commits.
9112 * configure.in (version 1.56),
9113 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
9114 when generating output files to configure the pic16 library,
9115 but now I've commented it out, since gputils aren't installed in the
9116 SF compile farm, so library won't compile
9118 * device/lib/Makefile.in (version 1.56): initially I've added in
9119 target 'all' the prerequestive 'model-pic16' so it compiled the
9120 pic16 library, but now I've commented it out for the same reasons
9122 * added targets 'model-pic16' and 'objects-pic16' to compile the
9124 * added target 'port-specific-objects-pic16' to handle the
9125 generated libraries and copy them into the build/ directory
9126 * added target 'clean-intermediate-pic16' to clean intermediate
9127 files into pic16 directory
9128 * in target 'installdirs' added line to create directory pic16 in
9129 the installation path
9131 * device/include/Makefile.in (version 1.11): in target 'install'
9132 added lines to copy all header files to installation path,
9133 * in target 'installdirs' added line create directory for pic16
9134 headers in the installation path

9149 * src/z80/main.c (_parseOptions): fixed the portmode= command line
9150 option so that it actually works. Made it specific to the z80, since
9151 the gbz80 doesn't have these kinds of I/O ports.
9153 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9155 * device/include/z180.h,

9168 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9170 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
9171 changed interrupt vector table generation to only emit declared vectors.
9172 * device/include/Makefile.in: added missing backslash
9173 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)

9177 Mainly changes to support compilation of the device libraries
9178 * src/pic16/device.c: stack is allocated via symbol and not
9179 via literal number. The symbol is placed in the corresponding
9180 position of the data ram
9181 * (pic16_dump_section): relocatable and absolute uninitialized
9182 data are now emitted in sorted order to reduce section naming,
9183 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
9184 weren't marked as being in the access bank,
9186 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
9188 Added portion of GNU PIC Library under the directory
9189 device/include/pic16 and device/lib/pic16. These files
9190 contain the declarations of SFRs for the PIC18Fxx2 devices.
9191 The directory is initialized via configure from toplevel.
9193 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
9195 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
9196 the spilllocations to be compared correctly
9198 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
9200 * src/SDCCast.c (decorateType): fixed bug introduced today
9202 2004-01-12 Borut Razem <borut.razem AT siol.net>

9220 * doc/sdccman.lyx: Moved and added some sections, small changes
9221 all over. Telling LaTeX to be less strict with word spacing
9222 to better keep the right margin. Changed some notes about
9223 maintainance of the ports in section 3.2.1 - is it OK like this?
9225 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

9262 UPPER for immediate operands,
9263 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
9265 * src/pic16/peeph.def: all peepholes with movff are commented out,
9266 because there is a problem in the pcode peep optimizer,
9267 * src/pic16/ralloc.c: the register allocator can now reuse local
9268 function symbols for another function. This saves register usage.
9269 * src/pic16/ralloc.h: added flag isLocal in structure regs,
9271 Added file src/pic16/NOTES with information about program writing on
9272 the current port version.

9281 * src/SDCCmain.c : fixed #872250: -l command line defined library
9282 files are scanned before standard library files
9284 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9304 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9307 * src/z80/main.c: added missed needLinkerScript flags (more than
9308 one port structure defined in these file)
9309 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

9325 needLinkerScript flag
9327 * src/pic16/gen.c (genAddrOf): fixed bug #863624
9328 * src/pic/glue.c: added variable udata_section_name to
9329 override default uninitialized data segment definition for
9330 devices only with SHAREBANK memory (reported from Erik Epetrich)
9331 * (pic14emitOverlay): modified to emit a commented overlay segment
9332 directive when no overlay data exist
9333 * (picglue): modified to emit uninitialized data segment
9334 according to udata_section_name

9339 arguments via -W option
9340 * src/pic16/main.c: added $l in _asmCmd, changed extension for
9341 object file from '.rel' to '.o' in port->linker structure,
9342 changed size of fptr from 2 to 3 in port structure
9344 2004-01-07 Borut Razem <borut.razem AT siol.net>
9346 * support/scripts/sdcc.nsi: update PATH
9347 * support/scripts/sdcc.ico: craeted
9349 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>

9352 * doc/Makefile: fix install
9354 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9356 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
9358 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

9360 include information about variables allocated to the overlay
9363 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9365 * as/mcs51/lkmain.c: Help about -Y option

9377 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9379 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
9380 (default behaviour).
9382 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9384 A python script to validate compiler diagnostic messages. It can be
9385 used to verify that sdcc complains about bad c source code and
9386 gives a good location of the error.
9387 * support/valdiag/Makefile,
9388 * support/valdiag/valdiag.py,
9389 * support/valdiag/tests/*
9391 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9393 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

9404 * src/common.h: added ifndef/define/endif macros
9405 around the header file.
9406 Bug reported from Jesus Calvino-Fraga
9408 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
9410 * sdcc.spec: updated
9411 * device/include/Makefile.in: don't install CVS directories
9412 * device/lib/Makefile.in: added removal of CVS directories after install
9413 * doc/Makefile: fixed install, added local_icons
9414 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
9415 * src/mcs51/gen.c (genRightShift): fixed bug #870788
9416 * src/ds390/gen.c (genRightShift): fixed bug #870788
9417 * src/SDCCast.c (decorateType): fixed bug #870781
9419 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9421 PIC16 port related changes:
9422 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
9423 added variable stackPos,
9425 * gen.c: genCall, assignResultValue: added support for
9426 pushing/retrieving function parameters to/from stack,
9427 genFunction,genEndFunction: setup stack frame for the
9429 genAddrOf: will be changed according to bug 863624
9431 * added files genutils.c and genutils.h which contain gen*
9432 debugged and optimised functions extracted from gen.c
9434 * glue.c: added variable 'externs' which holds extern symbols,
9435 pic16emitRegularMap: is modified to properly handle relocatable
9436 symbols under the new scheme,
9437 pic16createInterruptVect: is modified
9438 pic16printPublics: is modified to emit 'global' assembler directives,
9439 added pic16_printExterns to print extern symbols,
9440 pic16glue: initializes stack/frame pointer in the beginning of
9441 the assembly output. Temporary hack, will be corrected later,
9442 because gplink yet does not support stack and SDCC does not
9443 yet support a type of crt0.o object to create the final binary.
9445 * Removed many lines that contain 8051 legacy code.
9446 * The code is finally placed under a 'code' directive.
9447 * Added port specific options.
9449 * _process_pragma: simplified since now we do not need *special*
9450 include file to define SFR registers. But a separate header
9451 will be needed. This will be developed later.
9452 * _pic16_parseOptions: added, parses port specific options:
9453 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9454 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9455 --preplace-udata-with=
9457 * _pic16_setDefaultOptions: modified to initialize section names,
9458 but hack is temporarly out of order since it needs improvement.
9459 * _pic16_genAssemblerPreamble: configuration words are emitted by
9460 their address instead of their name. This part is incomplete and
9461 supports only the 18Fxx2 devices. Other devices will emit an error
9462 during assembly since they do not contain the same set of config
9464 * _pic16_genIVT: is modified,
9466 * pcode.c: added definitions for some hardware registers that are needed
9468 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9469 All PCI entries are updated. Now LFSR is supported.
9470 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9471 * added pic16_newpCodeOpLit2 to support instructions with
9472 two literal arguments
9473 * pic16_pCode2str: corrected code that emits assembler instructions
9474 with two literal operands and those that have an access bit modifier
9475 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9476 this fixes a bug which caused some labels to be lost, when an
9477 assembler directive was added, i.e. banksel,
9478 * pic16_FixRegisterBanking: improved logic that causes the insertion
9480 * InlineFunction: functions that are called once, are not any more
9481 inlined. This can be a port option in the future,
9483 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9485 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9486 hold the corresponding uninitialized symbols,
9487 * pic16_allocProcessorRegister: registers have explicit marked the
9489 * pic16_allocInternalRegister: registers are explicit marked as
9491 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9492 processing list, so bit registers were lost,
9495 * ralloc.h: added field 'accessBank' and original symbol operand
9496 in register definition,
9497 * removed the field isMapped from register definition,
9499 ** Several functions have been removed from various sources:
9500 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9501 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9502 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9503 pic16_assignRelocatableRegisters
9505 ** others have been introduced:
9506 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9507 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9509 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9511 * support/scripts/inc2h.pl: changed definition of BIT_AT
9512 to emit 'sbit at' instead of 'bit at'. This was a request.
9514 PIC16 port related preliminary changes:
9515 * gen.c: prefixed function popRegFromString with
9516 pic16_ and all references to it corrected
9517 * pcode.c: all pic16_pc_* hardware registers prefixed
9518 with underscore (_),
9519 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9520 * ralloc.c: newReg(): when register is REG_SFR then
9521 set address to rIdx,
9522 pic16_allocProcessorRegister(): marks register wasUsed=0
9523 pic16_writeUsedRegs(): added a call to assign processor
9524 registers via pic16_assignFixedRegisters
9526 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9528 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9529 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9530 variables in unused register banks. Also the SSEG is placed
9531 wherever there is enough space for it, and IDATA can be anywhere
9532 in internal RAM. For now compile using -Wl-Y[stack_size].
9533 The mem file is different for this option as well, since it
9534 makes no sense of talking about DSEG lenght.
9536 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9538 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9539 in certain cases, e.g. when ROM assignment, patch provided
9540 from Albert den Haan.
9542 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

10548 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
10549 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
10550 If they pop r0/r1 they must be called in the opposite order than aopOp().
10551 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
10552 (resp. --stack-auto), prepared for --xstack
10554 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10556 * doc/sdccman.lyx: reverted tables to those in cvs 1.64
10558 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10560 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
10561 these ports have their own __sdcc_external_start()
10563 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
10565 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10566 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10567 type for bits was changed. It resulted in bit variables becoming
10568 global, which is not permitted in PIC 14 assembly output.
10570 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10572 * doc/sdccman.lyx: various additions and updates. Rearranged sections
10574 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10576 Z80 and MCS51 linkers complaint if a public symbol is defined
10577 in more than one library module:

10583 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10585 A few small changes that speed up the peephole optimizer.
10589 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10591 Try to make the peephole optimizer smarter by maintaining
10592 an association between the assembly source code and the
10593 iCodes that originated them. Put this information to use
10594 with a new peephole rule condition "notVolatile" so that
10595 the rules can be aggressive yet still safe.
10600 * src/mcs51/peeph.def
10602 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10606 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10607 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10608 if the left or right operand symbols have the accuse flag set.
10610 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10612 Changed the type of the result of the ! (NOT) operator to char;
10613 previously it returned the same type as the source. This allows
10614 us to eliminate all the genFloatNot functions (all of its target
10615 implementations were very buggy) since !float can use the same
10618 * src/SDCCicode.c (ast2iCode): ! returns char
10619 * src/mcs51/gen.c (genNot, genNotFloat),
10620 * src/ds390/gen.c (genNot, genNotFloat),
10621 * src/z80/gen.c (genNot, genNotFloat),
10622 * src/pic/gen.c (genNot, genNotFloat),
10623 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

10627 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10628 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10629 during interrupts. Ensure WSAVE is located at a shared bank address.
10630 2. Fixed page selection in some places
10631 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10632 the registers name strings.
10633 4. Fixed "signed / unsigned compare" compiler warnings.
10634 5. The PIC port manages its own allocation of the general purpose
10635 registers, but makes no attempt to reuse them. As a result when
10636 compiling it soon runs out of general purpose registers. Some
10637 additional code was added to the files pcode.c and device.c to walk
10638 through the function call tree and rename the registers so that they
10648 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10649 genPlus() & genMinus() when the result is the same as left or right
10651 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10655 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10657 Made bitfield a distinct type from bit so that bitfields
10658 convert as per ANSI C and bits retain their traditional
10659 boolean style behaviour. Implemented bitfield support in
10667 * src/ds390/gen.c: bit v bitfield split
10668 * src/z80/gen.c: New support for bitfields
10669 * support/regression/tests/bitfields.c: reenabled z80,
10672 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10674 Rules 246.x, 247.x relate to bitfields, the others speed up
10675 access to xdata mapped I/O devices.
10677 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
10679 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10681 Cleaned up genPackBits and genUnpackBits and added two helper
10682 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
10683 for literal assignments in genPackBits (thanks to Frieder for
10689 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10691 Fixed bug #748310 (pointer to function type mishandled when the
10692 function name is omitted). Also fixed a SIGSEGV when a function
10693 attribute (reentrant, etc) is used on a non-function or on a
10694 function but misplaced before the parameter list.
10696 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
10698 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
10699 * support/Util/SDCCerr.h,
10700 * support/Util/SDCCerr.c: Added func attr misuse error msg
10702 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
10704 Fixed bug #787649 by anonymous
10705 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
10706 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
10708 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10721 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10723 Made the constant following the "interrupt" keyword optional. If
10724 omitted, the function will not automatically be given an entry
10725 in the interrupt vector table (similar to #pragma NOIV, but
10726 less syntacticly kludgy). The interrupt number is also now
10727 range checked. Also fixed a bug in the high order bit example
10734 * support/Util/SDCCerr.c
10735 * support/Util/SDCCerr.h

10743 * src/SDCCsymt.c (computeType): literals are handled the same way as any
10745 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
10746 be re-activated by defining REDUCE_LITERALS)
10747 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
10748 unsigned, but are signed by default
10749 * src/SDCCval.c (constVal): rearranged
10750 * src/SDCCval.c (valMod): preliminary fix
10751 * src/SDCCval.c (valCastLiteral): use TYPE_* types

11203 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
11204 the regression tests I'm not brave enough to enable 245.b, 245.c
11205 * doc/sdccman.lyx: added latex preamble for hyperref package.
11206 Using pdflatex this will give you a hyperlinked pdf file with

11247 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
11248 it can be defined with CFLAGS when running configure
11249 * src/SDCCmain.c: fixed compiling + linking with object files
11251 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

11256 * src/SDCCmain.c: linkOptions is changed to set *,
11257 added if/endif conditional macros to remove options help
11258 messages from optionsTable when a port is not configured, added
11259 support for the PIc16 port in the ports table, when executing
11260 the compiler with no port specified on command line, a default
11261 port is selected with the new macro DEFAULT_PORT which is
11262 defined in port.h, in setDefaultOptions() linkOptions is removed
11263 from initialization assignment, since now it is a set,
11264 parseCmdLine uses setParseWithComma for linkOptions, in
11265 linkEdit() linkOptions are accessed with new function indexSet()
11266 which returns the i'th item of a set variable. See SDCCset.c, in
11267 linkEdit() when calling buildCmdLine(), added linkOptions as
11268 last argument. Now users can pass arguments to gplink via the
11269 -Wl option, main() uses pic16glue() to glue up pic16 programs
11270 * src/SDCCpeeph.c: various changes to support pic16
11271 * src/SDCCset.c: added function void *indexSet(set *, int) to

11281 * src/pic16/glue.c: commented out some error producing lines
11282 * src/pic16/main.c: __config directives are commented out to stop
11283 gpasm complaining and test the linkage with gplink, _linkCmd and
11284 _asmCmd changed to be more gplink and gpasm friendly
11285 * src/pic16/peeph.def: peep rule 3 is commented out, since it
11286 produced an error when parsed, peep rule 12 is added to utilize
11287 movff, but it is commented out since the pCode does not support
11288 yet a command with 2 address arguments
11290 2003-05-18 <johan AT balder>
11292 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

12381 added aopGetUsesAcc() function to allow binary operators to
12382 fetch their operands in the correct order; made genMinus() emit
12383 compact code for X = LITERAL - Y
12385 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12386 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
12387 sprintf() in line 1267.
12389 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12390 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
12393 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12394 Changes to aslink (All the changes are marked with 'JCF'):
12396 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
12399 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
12400 area BSEG. Also moves, if possible, the DATA area down into the internal
12401 ram so more space is available.
12403 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
12406 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
12407 not bytes. Function summary() which creates a memory usage summary
12408 file with extension .mem. Reports of overlaping stack and small stack
12409 size. If the space for the stack is less than 16 bytes aslink trows a
12412 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
12413 the 8051. Option 'y' for memory summary output file.
12415 Changes to sdcc (All the changes are marked with 'JCF'):
12417 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
12419 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
12420 overlaying area for it (uses RegBankUsed[4]).
12422 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
12423 bank zero as used by default. By default aslink locates the stack
12424 (equivalent to --stack-after-data). Pass option 'y' to aslink for
12425 the creation of the .mem file. Delegates the allocation of data area
12426 to aslink (it is not longer 0x30 by default). If --stack-loc passes
12427 the begining of the stack area to aslink.
12429 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
12430 glue() in SDCCglue.c creates an area for it.
12432 2002-09-03 Borut Razem <borut.razem AT siol.net>
12433 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12434 sdcc/src/pic/glue.c:
12435 introduced atexit() handler for teporay files removal in case of
12436 errors, assertions, ...
12438 2002-08-29 Borut Razem <borut.razem AT siol.net>
12439 * sdcc/support/cpp2/auto-host_vc_in.h:
12440 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12441 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12442 Maybe there is a similar problem with BORLANDC? It should be checked!
12444 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12445 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12446 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12447 was not executed, and the compiler (cl) launched a warning:
12448 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12450 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12451 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
12453 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
12454 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
12456 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12457 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
12458 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
12459 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12460 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
12461 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
12462 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
12463 - added Release configuration in VS projects
12464 - review of compiler an linker options
12465 - VC .exe files are generated in bin_vc directory, not to interfere
12466 with binaries generated from other projects (cygwin, mingw, bcc ...)
12468 * sdcc/src/yacc.dsp: added
12470 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12471 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12472 and insert the version number definitions from .version
12474 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12476 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
12477 added - genarate auto-host.h using auto-host_vc_in.h as template
12480 removed from CVS, generated automatically
12482 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
12483 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12485 2002-08-11 Borut Razem <borut.razem AT siol.net>
12486 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12488 2002-08-10 Borut Razem <borut.razem AT siol.net>
12489 * src/SDCCmain.c (main):
12490 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12491 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12492 The consequence was that some temporary files were not removed.
12495 unification of code in functions tempfilename() and tempfile():
12496 function tempnam() is defined in Visual Studio 6.0 and .NET
12498 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12500 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12501 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
12502 - removed compiler command line option /WX: Treats all warnings as errors
12503 - update a list of source files, included into the project
12505 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12506 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12507 changed project type to Generic Project so that can be correcly converted to VS.NET project
12509 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12511 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
12513 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
12515 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12516 added return 0 statements after assert() to make compiler happy
12518 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12519 added newline in the def file to keep MSC compiler satisfied
12521 * sdcc/src/z80/gen.c:
12522 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
12523 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
12524 - solved MSC error in function aopDump()
12526 * sdcc_vc.h: define PREFIX as "\\sdcc"
12528 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
12529 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

12532 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
12533 - Rewrote the register banking algorithm.
12534 - Added pCode live-range analysis to registers (for now, only non-used and
12535 singly-used registers optimized away)
12537 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
12539 * 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.

12566 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
12568 2002-03-28 Johan Knol <johan AT balder>
12570 * src/SDCCval.c: fixed bug #532436
12572 2002-03-14 Scott Dattalo <scott AT dattalo.com>
12574 Added "char *Processor" field to the port structure.
12577 Added -p option. Allows port dependent processor to be specified.
12580 Initialized the new field char *Processor field to NULL in all ports
12583 Compiler generated registers for interrupt context saving
12584 were not getting allocated.
12586 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
12589 Fixed left shift. Will promote the left side of a left shift
12590 if a) left shifting more than size of operand or b) when assigned
12591 to something size > size of left side
12593 2002-03-14 Scott Dattalo <scott AT dattalo.com>

12597 analysis is restructured. ...
12599 * src/pic/device.h:
12602 * src/pic/device.c:
12603 Added. device.c is a PIC port hack to accomodate variations

12701 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
12703 * sdcc/src/SDCCloop.c:
12704 Previous fix was not good. basic blocks that have "break" or "return" are
12705 not really partof a loop , but live ranges used in these blocks should
12706 be live thru the entire loop, so set partOfLoop but don't add them to
12709 2002-02-21 <johan AT FRIJA>
12711 * src/SDCCcse.c: fixed bug #514308
12713 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
