836 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
838 Enabled VPATH feature: changed nearly all Makefiles (149 files).
839 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
841 One basic decision: e.g. src/clean.mk includes further files. In order
842 to make this work there are two solutions:
843 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
844 run configure on them. This way they can use
845 'include $(srcdir)/port-clean.mk'
846 - always include clean.mk by the Makefile at the same level. To avoid
847 that `make clean` tries to include and build Makefile.dep the
848 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
849 implemented, because now even `make uninstall` doesn't create
850 Makefile.in. clean.mk could be eliminated by pasting it in
853 * debugger/mcs51/Makefile.in: build own objects from library sources
854 (SLIB, SDCC) in current directory
856 * configure, configure.in: renamed --disable-device-lib-build in
857 --disable-device-lib; added --enable-doc, the required tools are
858 searched by configure; added result message; the toolchain for the
859 belonging ports are now only built, if the port is enabled.
861 * support/regression/*: all output is written in directory gen, because
862 the fwk and ports directories don't livet in the build tree using vpath
864 * doc/sdccman.lyx: renamed --disable-device-lib-build to
865 --disable-device-lib, added --enable-doc, added section VPATH
867 * sim/ucsim/configure.in,
868 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
869 z80 are enabled by default
871 2006-04-24 Raphael Neider <rneider AT web.de>
873 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
874 to config word, "pic14_"-prefixed some extern functions
875 (pic14_emitConfigWord): emit __config directive(s) if assignment to
876 config word has been found
877 * src/pic/device.h: added prototypes
878 * src/pic/pcode.c: added "pic14_"-prefix where needed
879 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
881 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
883 (pic14emitRegularMap): ignore config words,
884 (pic14createInterruptVect): moved generating __config directives away

900 * device/examples/main8051.c: deleted - it was removed from CVS

1142 implemented patch 1120823 Thanks to Willy De la Court (normal
1143 interrupts need an interrupt number now if they are made critical),
1144 and enabled nesting of critical functions though not for gbz80
1145 (genCritical, genEndCritical): added functions
1146 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1147 * src/z80/mappings.i: added "ei" to all mappings

1156 2006-03-16 Raphael Neider <rneider AT web.de>
1158 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
1159 the left operand is shorter than the result (c* = lit-c* + int),
1161 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1164 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1166 * src/.version: increased version number to 2.5.5
1167 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1168 linking is done manually in pic16 port's _linkEdit,
1169 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1170 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1171 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1172 allocate asmop as AOP_ACC,
1173 (aopForRemat): added parameter 'bool result' in function declaration,
1174 (pic16_aopGet): return AOP_ACC when accessing WREG,
1175 (pic16_popGetTempReg): minor modification,

1186 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1187 call to allocReg, not by manually allocating a new one,
1188 (pic16_assignRegisters): now before going through the register
1189 allocating functions mark all registers as free. This eliminates some
1190 side effects resulting from peephole parser done earlier in the backbone
1192 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1242 2006-03-06 Borut Razem <borut.razem AT siol.net>
1244 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1245 made the linker quiet

1250 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1251 which dumps before the function entry point a data byte which represents
1252 the number of the local variables used by the specified function, added
1253 'xinst' for initial support for Extended Instruction Support,
1254 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1255 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1256 port->fun_prefix anymore (may change later),
1257 (genFunction, genEndFunction): do not store/restore local registers for
1258 _main (this should take care the --main-return command line option in
1260 (genOr): removed some legacy pic-port instructions,
1261 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1262 performing operations with SFR's causes data to be written more than
1263 once to each SFR. Perhaps SFRs should be handled in special cases...
1264 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1266 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1267 into account for stack starting position,
1268 (struct OPTIONS pic16_optionsTable): added command line argument
1269 --extended or -y for Extended Instruction Support,
1270 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1271 (deassignLRs): *** perhaps the most important change, old 'for' code
1272 (commented out for reference), didn't account for some registers which
1273 were left marked 'not free' after a pointer operation. The change
1274 reduces register usage a lot in some cases
1276 2006-03-04 Borut Razem <borut.razem AT siol.net>
1278 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

3551 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3552 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3553 always available in leading double underscore form. The C99 support is
3554 mostly missing, but it's a start.
3555 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3556 reserved identifier "__data".

3634 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3636 * device/lib/printf_large.c: removed inline assembly for portability and
3637 readability. Use printf_fast if speed or size are more important.
3638 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3639 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3641 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3643 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3644 prevent compiler warning
3646 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3648 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3649 moved to level 0 and declared as static. Also they are explicit
3650 placed in access bank. This was necessery because some times they
3651 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3652 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3653 optimizations. Currently only compare to unsigned char is implemented,
3654 * src/pic16/gen.c: added fReturnIdx array,
3655 * (struct resolvedIfx) is moved to gen.h and made public,
3656 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3657 * (aopForSym): added an optimization to directly store in stack of
3658 the operand of a SEND iCode,
3659 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3660 but as registers instead (AOP_REG) using the fReturnIdx array,
3661 * (pic16_freeAsmop): remove the freed register from the
3662 _G.sregsAlloc field,
3663 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3664 a compare of 'WREG',
3665 * (pic16_popGetTempRegCond): changed function prototype, now
3666 function takes also a bitVector argument v which holds the current
3667 set of registers that are allocated for stack access by aopForSym,
3668 registers allocated in aopForSym for accessing stack symbols are not
3669 any more part of the functions usedRegs field,
3670 * (genCall): some times aopOp is called for a stack variable to be
3671 send, aopForSym might perform the push, if this is true make sure
3672 that genCall doesn't push the variable twice by testing _G.resDirect,
3673 * (genFunction): changed testing for unspecified interrupt number
3674 from 256 to INTNO_UNSPEC,
3675 * modified selection scheme of frame pointer generation. Previously
3676 if function did use local registers a frame pointer was generated,
3677 now a frame pointer is generated only if function has arguments
3678 (that need PLUSW2 register access), or has stack arguments, or the
3679 compiler is not instructed to omit the frame pointer,
3680 * (genEndFunction): before restoring local registers that were saved
3681 in the function preamble, also restore the registers that *might*
3682 have been allocated for stack access,
3683 * (genRet): removed some old comments,
3684 * (genCmp, the active (RN's) version): added a call to the
3685 pic16_genCmp_special function to perform the compare with a more
3686 robust and optimized way,
3687 * (genInline): a feature has been added in inline code generation,
3688 which allows a wildcard variable substitution when writing inline
3689 assembly. Code is incomplete and experimental therefore undocumented,
3690 * (genCast): changed order of aopOp for result and right to allow
3691 aopForSym to directly load the result if possible,
3692 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3693 perform an optimized compare on some selected special occasions,
3694 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3695 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3696 generate an IVT any more,
3697 * src/pic16/main.c (pic16_optionsTable): added command line option
3699 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3700 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3702 * src/pic16/NOTES: Raphael Neider added in list of active developers
3703 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3704 jumptable_end to prevent bug #,
3705 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3706 inCond and outCond fields,
3707 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3708 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3709 turn off register spilling,
3710 * (packRegsForOneUse): synced with other ports' versions although it
3711 is not used currently,
3712 * (pic16_packRegisters): added an optimization while reading
3713 structure bitfields, some registers may be saved (malloc code is
3714 decreased by 80 bytes)
3716 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3718 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3719 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3720 this can be optimized more?
3722 2005-03-10 Raphael Neider <rneider AT web.de>
3724 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3725 genNearPointerGet): (hopefully) fixed access to bitfields via
3726 pointers (p->bitN = x; and x = p->bitN; failed)
3728 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

4339 2004-12-02 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4341 * src/SDCCpeeph.c (callFuncByName): support combined peephole rule
4343 (setFromConditionArgs): friendly operand parser for peephole rules,
4344 (operandBaseName, operandsNotRelated): new peephole condition
4345 "operandsNotRelated" -- similar to "operandsNotSame", but takes
4346 architecture specific register naming into account, handles n-way
4347 comparisons, and supports quoted literals
4348 * src/mcs51/peeph.def: restored rule 177.d with an extra condition
4350 2004-12-02 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

4358 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4360 Adding support for replacing ljmps with sjmps in jumptables
4361 generated for switch statements. For now you need to set the
4362 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4363 Now 4 algorithms for mcs51 jumptable generation are used:
4364 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4365 addresses loaded pc-relative for up to 112 cases and stack-pushing
4366 target addresses loaded with offset from dptr for up to 256 cases.
4368 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
4369 * src/mcs51/main.c: adapted constants for switch table generation
4370 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

4392 Large cummulative patch for pic16 port.
4393 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
4394 to call when a stack overflow occurs,
4395 * (malloc.h): added CVS Id tag,
4396 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4398 * added libc directory. The current version of LibC contains string
4399 functions, ctype functions and macros and some functions of the
4400 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4401 be extensively tested in the future. Standard disclaimer here.
4402 Library is not automatically build yet. But one can build it by
4403 invoking 'make' inside the libc directory.
4404 * added ADC library under libio. Preliminary version yet.
4406 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

4413 * (genUminusFloat): fixed for pic16, ported code from mcs51,
4414 * (pic16_storeForReturn): optimized return of 0,
4415 * (genCmp): experimental code for new genCmp which uses PIC18's
4416 special compare&skip instructions. Initial tests fail some times
4417 with variables grater than 1 byte in size, so new code is disabled,
4418 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4420 * (genCast): began a fix to optimize the casting of a bit to another
4421 bit, now assigning a bitfield to another bitfield will fail, sorry,
4422 * src/pic16/main.c: disabled the use of lr-support feature,
4423 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
4424 * added some function prototypes, added function _debugf prototype,

4426 bits with offset (case PO_GPR_BIT),
4427 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
4429 * (isBankInstruction): modified to return 0 for no banking instruction,
4430 and 1 for banking instruction,
4431 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4432 caused stop processing pCodes after a inline assembly block,
4433 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4434 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4435 registers when it shouldn't,
4436 * src/pic16/ralloc.c (allocReg): add preliminary support for
4437 supporting a limited set of temporary registers,
4439 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4441 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4442 genDataPointerSet): ensure assignments always copy in MSB to LSB
4444 (loadRegFromAop): recognize CLRH optimization,
4445 (genFunction): optimize RECEIVE iCodes in reentrant functions
4447 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4449 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
4450 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
4452 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08
4453 * src/hc08/main.c (_hc08_setDefaultOptions): default xdata to be
4454 contiguous with data

4458 * device/lib/_gptrget.c (_gptrget),
4459 * device/lib/_gptrgetc.c (_gptrgetc),
4460 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
4461 instead of sjmp to ret
4462 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
4463 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
4465 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

7437 * src/SDCCicode.c (geniCodeAdd): fixed part of bug #877103
7439 2004-01-16 Klaus Flittner <klaus_flittner AT gmx.de>
7441 * src/ds390/gen.c (aopOp3): fixed the assignment of different dptrs to
7444 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7446 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7447 loaded with the linker search paths (-L arguments) and the libraries
7448 to be linked with the current source (-l arguments). Changes
7449 currently will affect only the pic16 port.
7450 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7451 include path the port specific paths and port specific libraries,
7452 * gplink command now contains the $3 argument,
7453 * src/pic16/device.h,
7454 * src/pic16/device.c,: structure PIC_device is made public and
7455 renamed to PIC16_device, the same for variable Pics which is renamed
7456 to Pics16. Updated all references to them.
7457 * src/pic16/glue.c (pic16glue): corrected bug with code
7458 initialization which bypassed the variable initializations block.
7460 * device/lib/pic16/Makefile.rules: removed --penable-stack from
7461 COMPILE_FLAGS and added the --nostdinc option
7463 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7465 * device/include/mc68hc908jb8.h: Register defs for another member
7466 of the hc08 family. Contributed by Bjorn Bringert - thanks!
7468 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
7470 Documenting changes from previous commits.
7471 * configure.in (version 1.56),
7472 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7473 when generating output files to configure the pic16 library,
7474 but now I've commented it out, since gputils aren't installed in the
7475 SF compile farm, so library won't compile
7477 * device/lib/Makefile.in (version 1.56): initially I've added in
7478 target 'all' the prerequestive 'model-pic16' so it compiled the
7479 pic16 library, but now I've commented it out for the same reasons
7481 * added targets 'model-pic16' and 'objects-pic16' to compile the
7483 * added target 'port-specific-objects-pic16' to handle the
7484 generated libraries and copy them into the build/ directory
7485 * added target 'clean-intermediate-pic16' to clean intermediate
7486 files into pic16 directory
7487 * in target 'installdirs' added line to create directory pic16 in
7488 the installation path
7490 * device/include/Makefile.in (version 1.11): in target 'install'
7491 added lines to copy all header files to installation path,
7492 * in target 'installdirs' added line create directory for pic16
7493 headers in the installation path
7495 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

7508 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7509 option so that it actually works. Made it specific to the z80, since
7510 the gbz80 doesn't have these kinds of I/O ports.
7512 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7514 * device/include/z180.h,

7523 portmode; added deprecation warning for bank= and protmode= forms.
7524 Also, guard against buffer overflow.
7525 * src/z80/gen.c (aopGet): generate better code for sfr banked read
7527 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7529 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
7530 changed interrupt vector table generation to only emit declared vectors.
7531 * device/include/Makefile.in: added missing backslash
7532 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
7534 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7536 Mainly changes to support compilation of the device libraries
7537 * src/pic16/device.c: stack is allocated via symbol and not
7538 via literal number. The symbol is placed in the corresponding
7539 position of the data ram
7540 * (pic16_dump_section): relocatable and absolute uninitialized
7541 data are now emitted in sorted order to reduce section naming,
7542 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7543 weren't marked as being in the access bank,
7545 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7547 Added portion of GNU PIC Library under the directory
7548 device/include/pic16 and device/lib/pic16. These files
7549 contain the declarations of SFRs for the PIC18Fxx2 devices.
7550 The directory is initialized via configure from toplevel.
7552 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
7554 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
7555 the spilllocations to be compared correctly
7557 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
7559 * src/SDCCast.c (decorateType): fixed bug introduced today
7561 2004-01-12 Borut Razem <borut.razem AT siol.net>
7563 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

7566 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
7568 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
7569 in simpler and even better code
7571 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
7573 * src/SDCCicode.c (operandOperation): fixed bug #874819

7577 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7579 * doc/sdccman.lyx: Moved and added some sections, small changes
7580 all over. Telling LaTeX to be less strict with word spacing
7581 to better keep the right margin. Changed some notes about
7582 maintainance of the ports in section 3.2.1 - is it OK like this?
7584 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
7586 SDCC source changes:
7587 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

7621 UPPER for immediate operands,
7622 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7624 * src/pic16/peeph.def: all peepholes with movff are commented out,
7625 because there is a problem in the pcode peep optimizer,
7626 * src/pic16/ralloc.c: the register allocator can now reuse local
7627 function symbols for another function. This saves register usage.
7628 * src/pic16/ralloc.h: added flag isLocal in structure regs,
7630 Added file src/pic16/NOTES with information about program writing on
7631 the current port version.

7640 * src/SDCCmain.c : fixed #872250: -l command line defined library
7641 files are scanned before standard library files
7643 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7663 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7666 * src/z80/main.c: added missed needLinkerScript flags (more than
7667 one port structure defined in these file)
7668 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

7684 needLinkerScript flag
7686 * src/pic16/gen.c (genAddrOf): fixed bug #863624
7687 * src/pic/glue.c: added variable udata_section_name to
7688 override default uninitialized data segment definition for
7689 devices only with SHAREBANK memory (reported from Erik Epetrich)
7690 * (pic14emitOverlay): modified to emit a commented overlay segment
7691 directive when no overlay data exist
7692 * (picglue): modified to emit uninitialized data segment
7693 according to udata_section_name

7698 arguments via -W option
7699 * src/pic16/main.c: added $l in _asmCmd, changed extension for
7700 object file from '.rel' to '.o' in port->linker structure,
7701 changed size of fptr from 2 to 3 in port structure
7703 2004-01-07 Borut Razem <borut.razem AT siol.net>
7705 * support/scripts/sdcc.nsi: update PATH
7706 * support/scripts/sdcc.ico: craeted
7708 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>

7719 include information about variables allocated to the overlay
7722 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7724 * as/mcs51/lkmain.c: Help about -Y option

7736 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7738 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7739 (default behaviour).
7741 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7743 A python script to validate compiler diagnostic messages. It can be
7744 used to verify that sdcc complains about bad c source code and
7745 gives a good location of the error.
7746 * support/valdiag/Makefile,
7747 * support/valdiag/valdiag.py,
7748 * support/valdiag/tests/*
7750 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7752 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
7753 * src/SDCCsymt.c (newEnumType),

7761 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7763 * src/common.h: added ifndef/define/endif macros
7764 around the header file.
7765 Bug reported from Jesus Calvino-Fraga
7767 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7769 * sdcc.spec: updated
7770 * device/include/Makefile.in: don't install CVS directories
7771 * device/lib/Makefile.in: added removal of CVS directories after install
7772 * doc/Makefile: fixed install, added local_icons
7773 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7774 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7775 * src/ds390/gen.c (genRightShift): fixed bug #870788
7776 * src/SDCCast.c (decorateType): fixed bug #870781
7778 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7780 PIC16 port related changes:
7781 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7782 added variable stackPos,
7784 * gen.c: genCall, assignResultValue: added support for
7785 pushing/retrieving function parameters to/from stack,
7786 genFunction,genEndFunction: setup stack frame for the
7788 genAddrOf: will be changed according to bug 863624
7790 * added files genutils.c and genutils.h which contain gen*
7791 debugged and optimised functions extracted from gen.c
7793 * glue.c: added variable 'externs' which holds extern symbols,
7794 pic16emitRegularMap: is modified to properly handle relocatable
7795 symbols under the new scheme,
7796 pic16createInterruptVect: is modified
7797 pic16printPublics: is modified to emit 'global' assembler directives,
7798 added pic16_printExterns to print extern symbols,
7799 pic16glue: initializes stack/frame pointer in the beginning of
7800 the assembly output. Temporary hack, will be corrected later,
7801 because gplink yet does not support stack and SDCC does not
7802 yet support a type of crt0.o object to create the final binary.
7804 * Removed many lines that contain 8051 legacy code.
7805 * The code is finally placed under a 'code' directive.
7806 * Added port specific options.
7808 * _process_pragma: simplified since now we do not need *special*
7809 include file to define SFR registers. But a separate header
7810 will be needed. This will be developed later.
7811 * _pic16_parseOptions: added, parses port specific options:
7812 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7813 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7814 --preplace-udata-with=
7816 * _pic16_setDefaultOptions: modified to initialize section names,
7817 but hack is temporarly out of order since it needs improvement.
7818 * _pic16_genAssemblerPreamble: configuration words are emitted by
7819 their address instead of their name. This part is incomplete and
7820 supports only the 18Fxx2 devices. Other devices will emit an error
7821 during assembly since they do not contain the same set of config
7823 * _pic16_genIVT: is modified,
7825 * pcode.c: added definitions for some hardware registers that are needed
7827 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7828 All PCI entries are updated. Now LFSR is supported.
7829 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7830 * added pic16_newpCodeOpLit2 to support instructions with
7831 two literal arguments
7832 * pic16_pCode2str: corrected code that emits assembler instructions
7833 with two literal operands and those that have an access bit modifier
7834 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7835 this fixes a bug which caused some labels to be lost, when an
7836 assembler directive was added, i.e. banksel,
7837 * pic16_FixRegisterBanking: improved logic that causes the insertion
7839 * InlineFunction: functions that are called once, are not any more
7840 inlined. This can be a port option in the future,
7842 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7844 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7845 hold the corresponding uninitialized symbols,
7846 * pic16_allocProcessorRegister: registers have explicit marked the
7848 * pic16_allocInternalRegister: registers are explicit marked as
7850 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7851 processing list, so bit registers were lost,
7854 * ralloc.h: added field 'accessBank' and original symbol operand
7855 in register definition,
7856 * removed the field isMapped from register definition,
7858 ** Several functions have been removed from various sources:
7859 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7860 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7861 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7862 pic16_assignRelocatableRegisters
7864 ** others have been introduced:
7865 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7866 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7868 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7870 * support/scripts/inc2h.pl: changed definition of BIT_AT
7871 to emit 'sbit at' instead of 'bit at'. This was a request.
7873 PIC16 port related preliminary changes:
7874 * gen.c: prefixed function popRegFromString with
7875 pic16_ and all references to it corrected
7876 * pcode.c: all pic16_pc_* hardware registers prefixed
7877 with underscore (_),
7878 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7879 * ralloc.c: newReg(): when register is REG_SFR then
7880 set address to rIdx,
7881 pic16_allocProcessorRegister(): marks register wasUsed=0
7882 pic16_writeUsedRegs(): added a call to assign processor
7883 registers via pic16_assignFixedRegisters
7885 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7887 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7888 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7889 variables in unused register banks. Also the SSEG is placed
7890 wherever there is enough space for it, and IDATA can be anywhere
7891 in internal RAM. For now compile using -Wl-Y[stack_size].
7892 The mem file is different for this option as well, since it
7893 makes no sense of talking about DSEG lenght.
7895 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7897 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7898 in certain cases, e.g. when ROM assignment, patch provided
7899 from Albert den Haan.
7901 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8920 these ports have their own __sdcc_external_start()
8922 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8924 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8925 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8926 type for bits was changed. It resulted in bit variables becoming
8927 global, which is not permitted in PIC 14 assembly output.
8929 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8931 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8944 A few small changes that speed up the peephole optimizer.
8948 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8950 Try to make the peephole optimizer smarter by maintaining
8951 an association between the assembly source code and the
8952 iCodes that originated them. Put this information to use
8953 with a new peephole rule condition "notVolatile" so that
8954 the rules can be aggressive yet still safe.
8959 * src/mcs51/peeph.def
8961 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8965 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8966 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8967 if the left or right operand symbols have the accuse flag set.
8969 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8971 Changed the type of the result of the ! (NOT) operator to char;
8972 previously it returned the same type as the source. This allows
8973 us to eliminate all the genFloatNot functions (all of its target
8974 implementations were very buggy) since !float can use the same
8977 * src/SDCCicode.c (ast2iCode): ! returns char

8986 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8987 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8988 during interrupts. Ensure WSAVE is located at a shared bank address.
8989 2. Fixed page selection in some places
8990 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8991 the registers name strings.
8992 4. Fixed "signed / unsigned compare" compiler warnings.
8993 5. The PIC port manages its own allocation of the general purpose
8994 registers, but makes no attempt to reuse them. As a result when
8995 compiling it soon runs out of general purpose registers. Some
8996 additional code was added to the files pcode.c and device.c to walk
8997 through the function call tree and rename the registers so that they
9007 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

9014 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9016 Made bitfield a distinct type from bit so that bitfields
9017 convert as per ANSI C and bits retain their traditional
9018 boolean style behaviour. Implemented bitfield support in
9026 * src/ds390/gen.c: bit v bitfield split
9027 * src/z80/gen.c: New support for bitfields
9028 * support/regression/tests/bitfields.c: reenabled z80,
9031 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9033 Rules 246.x, 247.x relate to bitfields, the others speed up
9034 access to xdata mapped I/O devices.
9036 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9038 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9040 Cleaned up genPackBits and genUnpackBits and added two helper
9041 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9042 for literal assignments in genPackBits (thanks to Frieder for
9048 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9050 Fixed bug #748310 (pointer to function type mishandled when the
9051 function name is omitted). Also fixed a SIGSEGV when a function
9052 attribute (reentrant, etc) is used on a non-function or on a
9053 function but misplaced before the parameter list.
9055 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9057 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

9080 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9082 Made the constant following the "interrupt" keyword optional. If
9083 omitted, the function will not automatically be given an entry
9084 in the interrupt vector table (similar to #pragma NOIV, but
9085 less syntacticly kludgy). The interrupt number is also now
9086 range checked. Also fixed a bug in the high order bit example

9100 * src/SDCCicode.c (operandOperation): rewritten some ops
9101 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9102 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9104 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9105 be re-activated by defining REDUCE_LITERALS)
9106 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9107 unsigned, but are signed by default
9108 * src/SDCCval.c (constVal): rearranged
9109 * src/SDCCval.c (valMod): preliminary fix
9110 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9533 for a non-native english speaker.
9534 Please feel free to add to the manual or to correct my changes.

9562 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
9563 the regression tests I'm not brave enough to enable 245.b, 245.c
9564 * doc/sdccman.lyx: added latex preamble for hyperref package.
9565 Using pdflatex this will give you a hyperlinked pdf file with
9566 bookmarks. (prepend '%' before /usepackage if this breaks something)

9582 Applied patch from bug 737905 (renamed yylineo to mylineno):
9589 * src/pic16/pcode.c: Cleaned warnings
9590 * src/pic16/pcodeflow.c: Cleaned warnings
9591 * src/pic16/pcoderegs.c: Cleaned warnings

9604 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
9606 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
9607 it can be defined with CFLAGS when running configure
9608 * src/SDCCmain.c: fixed compiling + linking with object files
9610 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
9612 * configure.in: configure for pic16 port,
9613 added --disable-pic16-port
9614 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9615 * src/SDCCmain.c: linkOptions is changed to set *,
9616 added if/endif conditional macros to remove options help
9617 messages from optionsTable when a port is not configured, added
9618 support for the PIc16 port in the ports table, when executing
9619 the compiler with no port specified on command line, a default
9620 port is selected with the new macro DEFAULT_PORT which is
9621 defined in port.h, in setDefaultOptions() linkOptions is removed
9622 from initialization assignment, since now it is a set,
9623 parseCmdLine uses setParseWithComma for linkOptions, in
9624 linkEdit() linkOptions are accessed with new function indexSet()
9625 which returns the i'th item of a set variable. See SDCCset.c, in
9626 linkEdit() when calling buildCmdLine(), added linkOptions as
9627 last argument. Now users can pass arguments to gplink via the
9628 -Wl option, main() uses pic16glue() to glue up pic16 programs
9629 * src/SDCCpeeph.c: various changes to support pic16

9638 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
9640 * src/pic16/glue.c: commented out some error producing lines
9641 * src/pic16/main.c: __config directives are commented out to stop
9642 gpasm complaining and test the linkage with gplink, _linkCmd and
9643 _asmCmd changed to be more gplink and gpasm friendly
9644 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9645 produced an error when parsed, peep rule 12 is added to utilize
9646 movff, but it is commented out since the pCode does not support
9647 yet a command with 2 address arguments
9649 2003-05-18 <johan AT balder>
9651 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
9652 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9671 on entry now. Add tbreak. Other enhancements and fixes for use
9674 2003-05-12 Borut Razem <borut.razem AT siol.net>
9676 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
9678 2003-05-11 Borut Razem <borut.razem AT siol.net>
9680 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9681 the path of bin directory, so that PATH is the only env. variable, which has to be set
9682 in case of standard installation.
9683 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

10715 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10716 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10717 following files to include the previous two files: aslink.dsp,
10718 Makefile.aslink, Makefile.bcc, and Makefile.in.
10720 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10721 .adb instead of .cdb
10723 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10725 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10726 value from option --iram-size.
10728 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10730 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10733 2002-09-18 <wiml AT hhhh.org>
10735 * SDCClrange.h: exposed setFromRange() and setToRange()
10736 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10737 packRegsForAccUse() (bug 542397)
10738 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10739 multiple times and emitting the fetch operations more than once
10740 added aopGetUsesAcc() function to allow binary operators to
10741 fetch their operands in the correct order; made genMinus() emit
10742 compact code for X = LITERAL - Y
10744 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10745 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10746 sprintf() in line 1267.
10748 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10749 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10752 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10753 Changes to aslink (All the changes are marked with 'JCF'):
10755 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10758 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10759 area BSEG. Also moves, if possible, the DATA area down into the internal
10760 ram so more space is available.
10762 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10765 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10766 not bytes. Function summary() which creates a memory usage summary
10767 file with extension .mem. Reports of overlaping stack and small stack
10768 size. If the space for the stack is less than 16 bytes aslink trows a
10771 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10772 the 8051. Option 'y' for memory summary output file.
10774 Changes to sdcc (All the changes are marked with 'JCF'):
10776 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10778 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10779 overlaying area for it (uses RegBankUsed[4]).
10781 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10782 bank zero as used by default. By default aslink locates the stack
10783 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10784 the creation of the .mem file. Delegates the allocation of data area
10785 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10786 the begining of the stack area to aslink.
10788 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10789 glue() in SDCCglue.c creates an area for it.
10791 2002-09-03 Borut Razem <borut.razem AT siol.net>
10792 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10793 sdcc/src/pic/glue.c:
10794 introduced atexit() handler for teporay files removal in case of
10795 errors, assertions, ...
10797 2002-08-29 Borut Razem <borut.razem AT siol.net>
10798 * sdcc/support/cpp2/auto-host_vc_in.h:
10799 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10800 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10801 Maybe there is a similar problem with BORLANDC? It should be checked!
10803 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10804 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10805 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10806 was not executed, and the compiler (cl) launched a warning:
10807 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10809 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>

10813 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10815 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10816 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10817 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10818 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10819 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10820 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10821 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10822 - added Release configuration in VS projects
10823 - review of compiler an linker options
10824 - VC .exe files are generated in bin_vc directory, not to interfere
10825 with binaries generated from other projects (cygwin, mingw, bcc ...)
10827 * sdcc/src/yacc.dsp: added
10829 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10830 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10831 and insert the version number definitions from .version
10833 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10835 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

10842 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10844 2002-08-11 Borut Razem <borut.razem AT siol.net>
10845 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10847 2002-08-10 Borut Razem <borut.razem AT siol.net>
10848 * src/SDCCmain.c (main):
10849 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10850 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10851 The consequence was that some temporary files were not removed.
10854 unification of code in functions tempfilename() and tempfile():
10855 function tempnam() is defined in Visual Studio 6.0 and .NET
10857 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10859 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10860 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10861 - removed compiler command line option /WX: Treats all warnings as errors
10862 - update a list of source files, included into the project
10864 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10865 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10866 changed project type to Generic Project so that can be correcly converted to VS.NET project
10868 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10870 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10872 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10874 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10875 added return 0 statements after assert() to make compiler happy
10877 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10878 added newline in the def file to keep MSC compiler satisfied
10880 * sdcc/src/z80/gen.c:
10881 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10882 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10883 - solved MSC error in function aopDump()
10885 * sdcc_vc.h: define PREFIX as "\\sdcc"
10887 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

11060 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11062 * sdcc/src/SDCCloop.c:
11063 Previous fix was not good. basic blocks that have "break" or "return" are
11064 not really partof a loop , but live ranges used in these blocks should
11065 be live thru the entire loop, so set partOfLoop but don't add them to
11068 2002-02-21 <johan AT FRIJA>
11070 * src/SDCCcse.c: fixed bug #514308
11072 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
