850 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
852 Enabled VPATH feature: changed nearly all Makefiles (149 files).
853 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
855 One basic decision: e.g. src/clean.mk includes further files. In order
856 to make this work there are two solutions:
857 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
858 run configure on them. This way they can use
859 'include $(srcdir)/port-clean.mk'
860 - always include clean.mk by the Makefile at the same level. To avoid
861 that `make clean` tries to include and build Makefile.dep the
862 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
863 implemented, because now even `make uninstall` doesn't create
864 Makefile.in. clean.mk could be eliminated by pasting it in
867 * debugger/mcs51/Makefile.in: build own objects from library sources
868 (SLIB, SDCC) in current directory
870 * configure, configure.in: renamed --disable-device-lib-build in
871 --disable-device-lib; added --enable-doc, the required tools are
872 searched by configure; added result message; the toolchain for the
873 belonging ports are now only built, if the port is enabled.
875 * support/regression/*: all output is written in directory gen, because
876 the fwk and ports directories don't livet in the build tree using vpath
878 * doc/sdccman.lyx: renamed --disable-device-lib-build to
879 --disable-device-lib, added --enable-doc, added section VPATH
881 * sim/ucsim/configure.in,
882 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
883 z80 are enabled by default
885 2006-04-24 Raphael Neider <rneider AT web.de>
887 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
888 to config word, "pic14_"-prefixed some extern functions
889 (pic14_emitConfigWord): emit __config directive(s) if assignment to
890 config word has been found
891 * src/pic/device.h: added prototypes
892 * src/pic/pcode.c: added "pic14_"-prefix where needed
893 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
895 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
897 (pic14emitRegularMap): ignore config words,
898 (pic14createInterruptVect): moved generating __config directives away
899 (picglue): have __config directives emitted

909 fixes #1469504 and #1474602,
910 (pCodeRegOptimizeRegUsage): fixed typo in comment
912 2006-04-24 Borut Razem <borut.razem AT siol.net>
914 * device/examples/main8051.c: deleted - it was removed from CVS
915 24.mar.2000 and after that modified 18.feb.2001, so it reappered
916 after the transition to Subversion
917 * src/SDCCalloc.h: deleted - it was removed from CVS
918 3.feb.2001 and after that modified 18.feb.2001, so it reappered

1156 implemented patch 1120823 Thanks to Willy De la Court (normal
1157 interrupts need an interrupt number now if they are made critical),
1158 and enabled nesting of critical functions though not for gbz80
1159 (genCritical, genEndCritical): added functions
1160 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1161 * src/z80/mappings.i: added "ei" to all mappings

1173 the left operand is shorter than the result (c* = lit-c* + int),
1175 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1178 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1180 * src/.version: increased version number to 2.5.5
1181 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1182 linking is done manually in pic16 port's _linkEdit,
1183 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1184 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1185 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1186 allocate asmop as AOP_ACC,
1187 (aopForRemat): added parameter 'bool result' in function declaration,
1188 (pic16_aopGet): return AOP_ACC when accessing WREG,
1189 (pic16_popGetTempReg): minor modification,

1200 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1201 call to allocReg, not by manually allocating a new one,
1202 (pic16_assignRegisters): now before going through the register
1203 allocating functions mark all registers as free. This eliminates some
1204 side effects resulting from peephole parser done earlier in the backbone
1206 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1264 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1265 which dumps before the function entry point a data byte which represents
1266 the number of the local variables used by the specified function, added
1267 'xinst' for initial support for Extended Instruction Support,
1268 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1269 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1270 port->fun_prefix anymore (may change later),
1271 (genFunction, genEndFunction): do not store/restore local registers for
1272 _main (this should take care the --main-return command line option in
1274 (genOr): removed some legacy pic-port instructions,
1275 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1276 performing operations with SFR's causes data to be written more than
1277 once to each SFR. Perhaps SFRs should be handled in special cases...
1278 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1280 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1281 into account for stack starting position,

1283 --extended or -y for Extended Instruction Support,
1284 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1285 (deassignLRs): *** perhaps the most important change, old 'for' code
1286 (commented out for reference), didn't account for some registers which
1287 were left marked 'not free' after a pointer operation. The change
1288 reduces register usage a lot in some cases
1290 2006-03-04 Borut Razem <borut.razem AT siol.net>

3565 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3566 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3567 always available in leading double underscore form. The C99 support is
3568 mostly missing, but it's a start.
3569 * support/regression/tests/bug-227710.c: fixed nonconforming use of

3650 * device/lib/printf_large.c: removed inline assembly for portability and
3651 readability. Use printf_fast if speed or size are more important.
3652 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3653 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3655 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3657 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3658 prevent compiler warning
3660 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3662 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3663 moved to level 0 and declared as static. Also they are explicit
3664 placed in access bank. This was necessery because some times they
3665 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3666 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3667 optimizations. Currently only compare to unsigned char is implemented,
3668 * src/pic16/gen.c: added fReturnIdx array,
3669 * (struct resolvedIfx) is moved to gen.h and made public,
3670 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3671 * (aopForSym): added an optimization to directly store in stack of
3672 the operand of a SEND iCode,
3673 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3674 but as registers instead (AOP_REG) using the fReturnIdx array,
3675 * (pic16_freeAsmop): remove the freed register from the
3676 _G.sregsAlloc field,
3677 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3678 a compare of 'WREG',
3679 * (pic16_popGetTempRegCond): changed function prototype, now
3680 function takes also a bitVector argument v which holds the current
3681 set of registers that are allocated for stack access by aopForSym,
3682 registers allocated in aopForSym for accessing stack symbols are not
3683 any more part of the functions usedRegs field,
3684 * (genCall): some times aopOp is called for a stack variable to be
3685 send, aopForSym might perform the push, if this is true make sure
3686 that genCall doesn't push the variable twice by testing _G.resDirect,
3687 * (genFunction): changed testing for unspecified interrupt number
3688 from 256 to INTNO_UNSPEC,
3689 * modified selection scheme of frame pointer generation. Previously
3690 if function did use local registers a frame pointer was generated,
3691 now a frame pointer is generated only if function has arguments
3692 (that need PLUSW2 register access), or has stack arguments, or the
3693 compiler is not instructed to omit the frame pointer,
3694 * (genEndFunction): before restoring local registers that were saved
3695 in the function preamble, also restore the registers that *might*
3696 have been allocated for stack access,
3697 * (genRet): removed some old comments,
3698 * (genCmp, the active (RN's) version): added a call to the
3699 pic16_genCmp_special function to perform the compare with a more
3700 robust and optimized way,
3701 * (genInline): a feature has been added in inline code generation,
3702 which allows a wildcard variable substitution when writing inline
3703 assembly. Code is incomplete and experimental therefore undocumented,
3704 * (genCast): changed order of aopOp for result and right to allow
3705 aopForSym to directly load the result if possible,
3706 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3707 perform an optimized compare on some selected special occasions,
3708 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3709 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3710 generate an IVT any more,
3711 * src/pic16/main.c (pic16_optionsTable): added command line option
3713 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3714 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3716 * src/pic16/NOTES: Raphael Neider added in list of active developers
3717 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3718 jumptable_end to prevent bug #,
3719 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3720 inCond and outCond fields,
3721 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3722 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3723 turn off register spilling,
3724 * (packRegsForOneUse): synced with other ports' versions although it
3725 is not used currently,
3726 * (pic16_packRegisters): added an optimization while reading
3727 structure bitfields, some registers may be saved (malloc code is
3728 decreased by 80 bytes)
3730 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3732 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3733 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3734 this can be optimized more?
3736 2005-03-10 Raphael Neider <rneider AT web.de>
3738 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3739 genNearPointerGet): (hopefully) fixed access to bitfields via
3740 pointers (p->bitN = x; and x = p->bitN; failed)
3742 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

4372 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4374 Adding support for replacing ljmps with sjmps in jumptables
4375 generated for switch statements. For now you need to set the
4376 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4377 Now 4 algorithms for mcs51 jumptable generation are used:
4378 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4379 addresses loaded pc-relative for up to 112 cases and stack-pushing
4380 target addresses loaded with offset from dptr for up to 256 cases.
4382 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
4383 * src/mcs51/main.c: adapted constants for switch table generation

4406 Large cummulative patch for pic16 port.
4407 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
4408 to call when a stack overflow occurs,
4409 * (malloc.h): added CVS Id tag,
4410 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4412 * added libc directory. The current version of LibC contains string
4413 functions, ctype functions and macros and some functions of the
4414 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4415 be extensively tested in the future. Standard disclaimer here.
4416 Library is not automatically build yet. But one can build it by
4417 invoking 'make' inside the libc directory.
4418 * added ADC library under libio. Preliminary version yet.
4420 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

4427 * (genUminusFloat): fixed for pic16, ported code from mcs51,
4428 * (pic16_storeForReturn): optimized return of 0,
4429 * (genCmp): experimental code for new genCmp which uses PIC18's
4430 special compare&skip instructions. Initial tests fail some times
4431 with variables grater than 1 byte in size, so new code is disabled,
4432 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4434 * (genCast): began a fix to optimize the casting of a bit to another
4435 bit, now assigning a bitfield to another bitfield will fail, sorry,
4436 * src/pic16/main.c: disabled the use of lr-support feature,
4437 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
4438 * added some function prototypes, added function _debugf prototype,

4440 bits with offset (case PO_GPR_BIT),
4441 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
4443 * (isBankInstruction): modified to return 0 for no banking instruction,
4444 and 1 for banking instruction,
4445 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4446 caused stop processing pCodes after a inline assembly block,
4447 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4448 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4449 registers when it shouldn't,
4450 * src/pic16/ralloc.c (allocReg): add preliminary support for
4451 supporting a limited set of temporary registers,
4453 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4455 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4456 genDataPointerSet): ensure assignments always copy in MSB to LSB
4458 (loadRegFromAop): recognize CLRH optimization,
4459 (genFunction): optimize RECEIVE iCodes in reentrant functions
4461 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4463 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
4464 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
4466 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

4477 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
4479 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

7458 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7460 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7461 loaded with the linker search paths (-L arguments) and the libraries
7462 to be linked with the current source (-l arguments). Changes
7463 currently will affect only the pic16 port.
7464 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7465 include path the port specific paths and port specific libraries,
7466 * gplink command now contains the $3 argument,
7467 * src/pic16/device.h,
7468 * src/pic16/device.c,: structure PIC_device is made public and
7469 renamed to PIC16_device, the same for variable Pics which is renamed
7470 to Pics16. Updated all references to them.
7471 * src/pic16/glue.c (pic16glue): corrected bug with code
7472 initialization which bypassed the variable initializations block.
7474 * device/lib/pic16/Makefile.rules: removed --penable-stack from
7475 COMPILE_FLAGS and added the --nostdinc option
7477 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7479 * device/include/mc68hc908jb8.h: Register defs for another member

7482 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
7484 Documenting changes from previous commits.
7485 * configure.in (version 1.56),
7486 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7487 when generating output files to configure the pic16 library,
7488 but now I've commented it out, since gputils aren't installed in the
7489 SF compile farm, so library won't compile
7491 * device/lib/Makefile.in (version 1.56): initially I've added in
7492 target 'all' the prerequestive 'model-pic16' so it compiled the
7493 pic16 library, but now I've commented it out for the same reasons
7495 * added targets 'model-pic16' and 'objects-pic16' to compile the
7497 * added target 'port-specific-objects-pic16' to handle the
7498 generated libraries and copy them into the build/ directory
7499 * added target 'clean-intermediate-pic16' to clean intermediate
7500 files into pic16 directory
7501 * in target 'installdirs' added line to create directory pic16 in
7502 the installation path
7504 * device/include/Makefile.in (version 1.11): in target 'install'
7505 added lines to copy all header files to installation path,
7506 * in target 'installdirs' added line create directory for pic16
7507 headers in the installation path
7509 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

7522 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7523 option so that it actually works. Made it specific to the z80, since
7524 the gbz80 doesn't have these kinds of I/O ports.
7526 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7528 * device/include/z180.h,

7541 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7543 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
7544 changed interrupt vector table generation to only emit declared vectors.
7545 * device/include/Makefile.in: added missing backslash
7546 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
7548 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7550 Mainly changes to support compilation of the device libraries
7551 * src/pic16/device.c: stack is allocated via symbol and not
7552 via literal number. The symbol is placed in the corresponding
7553 position of the data ram
7554 * (pic16_dump_section): relocatable and absolute uninitialized
7555 data are now emitted in sorted order to reduce section naming,
7556 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7557 weren't marked as being in the access bank,
7559 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7561 Added portion of GNU PIC Library under the directory
7562 device/include/pic16 and device/lib/pic16. These files
7563 contain the declarations of SFRs for the PIC18Fxx2 devices.
7564 The directory is initialized via configure from toplevel.
7566 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
7568 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
7569 the spilllocations to be compared correctly
7571 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
7573 * src/SDCCast.c (decorateType): fixed bug introduced today
7575 2004-01-12 Borut Razem <borut.razem AT siol.net>
7577 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

7580 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
7582 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
7583 in simpler and even better code
7585 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
7587 * src/SDCCicode.c (operandOperation): fixed bug #874819

7591 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7593 * doc/sdccman.lyx: Moved and added some sections, small changes
7594 all over. Telling LaTeX to be less strict with word spacing
7595 to better keep the right margin. Changed some notes about
7596 maintainance of the ports in section 3.2.1 - is it OK like this?
7598 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7634 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
7635 UPPER for immediate operands,
7636 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7638 * src/pic16/peeph.def: all peepholes with movff are commented out,
7639 because there is a problem in the pcode peep optimizer,
7640 * src/pic16/ralloc.c: the register allocator can now reuse local
7641 function symbols for another function. This saves register usage.
7642 * src/pic16/ralloc.h: added flag isLocal in structure regs,
7644 Added file src/pic16/NOTES with information about program writing on
7645 the current port version.

7654 * src/SDCCmain.c : fixed #872250: -l command line defined library
7655 files are scanned before standard library files
7657 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7674 gen51Code): more efficient parameter receive for --model-large
7677 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7680 * src/z80/main.c: added missed needLinkerScript flags (more than
7681 one port structure defined in these file)
7682 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

7698 needLinkerScript flag
7700 * src/pic16/gen.c (genAddrOf): fixed bug #863624
7701 * src/pic/glue.c: added variable udata_section_name to
7702 override default uninitialized data segment definition for
7703 devices only with SHAREBANK memory (reported from Erik Epetrich)
7704 * (pic14emitOverlay): modified to emit a commented overlay segment
7705 directive when no overlay data exist
7706 * (picglue): modified to emit uninitialized data segment
7707 according to udata_section_name

7713 * src/pic16/main.c: added $l in _asmCmd, changed extension for
7714 object file from '.rel' to '.o' in port->linker structure,
7715 changed size of fptr from 2 to 3 in port structure
7717 2004-01-07 Borut Razem <borut.razem AT siol.net>
7719 * support/scripts/sdcc.nsi: update PATH
7720 * support/scripts/sdcc.ico: craeted
7722 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>
7724 * device/include/Makefile.in: fix install
7725 * doc/Makefile: fix install
7727 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7729 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
7731 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

7733 include information about variables allocated to the overlay
7736 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7738 * as/mcs51/lkmain.c: Help about -Y option

7750 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7752 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7753 (default behaviour).
7755 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7757 A python script to validate compiler diagnostic messages. It can be
7758 used to verify that sdcc complains about bad c source code and
7759 gives a good location of the error.
7760 * support/valdiag/Makefile,
7761 * support/valdiag/valdiag.py,
7762 * support/valdiag/tests/*
7764 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7766 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
7767 * src/SDCCsymt.c (newEnumType),

7775 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7777 * src/common.h: added ifndef/define/endif macros
7778 around the header file.
7779 Bug reported from Jesus Calvino-Fraga
7781 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7783 * sdcc.spec: updated
7784 * device/include/Makefile.in: don't install CVS directories
7785 * device/lib/Makefile.in: added removal of CVS directories after install
7786 * doc/Makefile: fixed install, added local_icons
7787 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7788 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7789 * src/ds390/gen.c (genRightShift): fixed bug #870788
7790 * src/SDCCast.c (decorateType): fixed bug #870781
7792 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7794 PIC16 port related changes:
7795 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7796 added variable stackPos,
7798 * gen.c: genCall, assignResultValue: added support for
7799 pushing/retrieving function parameters to/from stack,
7800 genFunction,genEndFunction: setup stack frame for the
7802 genAddrOf: will be changed according to bug 863624
7804 * added files genutils.c and genutils.h which contain gen*
7805 debugged and optimised functions extracted from gen.c
7807 * glue.c: added variable 'externs' which holds extern symbols,
7808 pic16emitRegularMap: is modified to properly handle relocatable
7809 symbols under the new scheme,
7810 pic16createInterruptVect: is modified
7811 pic16printPublics: is modified to emit 'global' assembler directives,
7812 added pic16_printExterns to print extern symbols,
7813 pic16glue: initializes stack/frame pointer in the beginning of
7814 the assembly output. Temporary hack, will be corrected later,
7815 because gplink yet does not support stack and SDCC does not
7816 yet support a type of crt0.o object to create the final binary.
7818 * Removed many lines that contain 8051 legacy code.
7819 * The code is finally placed under a 'code' directive.
7820 * Added port specific options.
7822 * _process_pragma: simplified since now we do not need *special*
7823 include file to define SFR registers. But a separate header
7824 will be needed. This will be developed later.
7825 * _pic16_parseOptions: added, parses port specific options:
7826 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7827 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7828 --preplace-udata-with=
7830 * _pic16_setDefaultOptions: modified to initialize section names,
7831 but hack is temporarly out of order since it needs improvement.
7832 * _pic16_genAssemblerPreamble: configuration words are emitted by
7833 their address instead of their name. This part is incomplete and
7834 supports only the 18Fxx2 devices. Other devices will emit an error
7835 during assembly since they do not contain the same set of config
7837 * _pic16_genIVT: is modified,
7839 * pcode.c: added definitions for some hardware registers that are needed
7841 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7842 All PCI entries are updated. Now LFSR is supported.
7843 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7844 * added pic16_newpCodeOpLit2 to support instructions with
7845 two literal arguments
7846 * pic16_pCode2str: corrected code that emits assembler instructions
7847 with two literal operands and those that have an access bit modifier
7848 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7849 this fixes a bug which caused some labels to be lost, when an
7850 assembler directive was added, i.e. banksel,
7851 * pic16_FixRegisterBanking: improved logic that causes the insertion
7853 * InlineFunction: functions that are called once, are not any more
7854 inlined. This can be a port option in the future,
7856 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7858 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7859 hold the corresponding uninitialized symbols,
7860 * pic16_allocProcessorRegister: registers have explicit marked the
7862 * pic16_allocInternalRegister: registers are explicit marked as
7864 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7865 processing list, so bit registers were lost,
7868 * ralloc.h: added field 'accessBank' and original symbol operand
7869 in register definition,
7870 * removed the field isMapped from register definition,
7872 ** Several functions have been removed from various sources:
7873 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7874 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7875 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7876 pic16_assignRelocatableRegisters
7878 ** others have been introduced:
7879 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7880 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7882 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7884 * support/scripts/inc2h.pl: changed definition of BIT_AT
7885 to emit 'sbit at' instead of 'bit at'. This was a request.
7887 PIC16 port related preliminary changes:
7888 * gen.c: prefixed function popRegFromString with
7889 pic16_ and all references to it corrected
7890 * pcode.c: all pic16_pc_* hardware registers prefixed
7891 with underscore (_),
7892 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7893 * ralloc.c: newReg(): when register is REG_SFR then
7894 set address to rIdx,
7895 pic16_allocProcessorRegister(): marks register wasUsed=0
7896 pic16_writeUsedRegs(): added a call to assign processor
7897 registers via pic16_assignFixedRegisters
7899 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7901 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7902 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7903 variables in unused register banks. Also the SSEG is placed
7904 wherever there is enough space for it, and IDATA can be anywhere
7905 in internal RAM. For now compile using -Wl-Y[stack_size].
7906 The mem file is different for this option as well, since it
7907 makes no sense of talking about DSEG lenght.
7909 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7911 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7912 in certain cases, e.g. when ROM assignment, patch provided
7913 from Albert den Haan.
7915 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>
7917 Many signedness and type propagation fixes:
7918 * src/SDCCicode.c: made geniCodeCast() static
7919 replaced SPEC_ by IS_ (cosmetic)
7920 (operandOperation): fixed div and mod operation
7921 (usualBinaryConversions): added support for promotion of char
7922 (geniCodeMultiply): replaced (unsigned long) by (TYPE_UDWORD)
7923 (geniCodeDivision): replaced (unsigned long) by (TYPE_UDWORD)

8919 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8920 copied from genNearPointerSet()
8921 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8922 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
8923 If they pop r0/r1 they must be called in the opposite order than aopOp().
8924 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
8925 (resp. --stack-auto), prepared for --xstack

8934 these ports have their own __sdcc_external_start()
8936 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8938 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8939 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8940 type for bits was changed. It resulted in bit variables becoming
8941 global, which is not permitted in PIC 14 assembly output.
8943 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8945 * doc/sdccman.lyx: various additions and updates. Rearranged sections
8947 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8949 Z80 and MCS51 linkers complaint if a public symbol is defined

8958 A few small changes that speed up the peephole optimizer.
8962 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8964 Try to make the peephole optimizer smarter by maintaining
8965 an association between the assembly source code and the
8966 iCodes that originated them. Put this information to use
8967 with a new peephole rule condition "notVolatile" so that
8968 the rules can be aggressive yet still safe.
8973 * src/mcs51/peeph.def
8975 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8979 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8980 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8981 if the left or right operand symbols have the accuse flag set.
8983 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8985 Changed the type of the result of the ! (NOT) operator to char;
8986 previously it returned the same type as the source. This allows
8987 us to eliminate all the genFloatNot functions (all of its target
8988 implementations were very buggy) since !float can use the same
8991 * src/SDCCicode.c (ast2iCode): ! returns char
8992 * src/mcs51/gen.c (genNot, genNotFloat),
8993 * src/ds390/gen.c (genNot, genNotFloat),
8994 * src/z80/gen.c (genNot, genNotFloat),
8995 * src/pic/gen.c (genNot, genNotFloat),
8996 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

9000 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9001 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9002 during interrupts. Ensure WSAVE is located at a shared bank address.
9003 2. Fixed page selection in some places
9004 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9005 the registers name strings.
9006 4. Fixed "signed / unsigned compare" compiler warnings.
9007 5. The PIC port manages its own allocation of the general purpose
9008 registers, but makes no attempt to reuse them. As a result when
9009 compiling it soon runs out of general purpose registers. Some
9010 additional code was added to the files pcode.c and device.c to walk
9011 through the function call tree and rename the registers so that they
9021 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9022 genPlus() & genMinus() when the result is the same as left or right

9028 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9030 Made bitfield a distinct type from bit so that bitfields
9031 convert as per ANSI C and bits retain their traditional
9032 boolean style behaviour. Implemented bitfield support in
9040 * src/ds390/gen.c: bit v bitfield split
9041 * src/z80/gen.c: New support for bitfields
9042 * support/regression/tests/bitfields.c: reenabled z80,
9045 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9047 Rules 246.x, 247.x relate to bitfields, the others speed up
9048 access to xdata mapped I/O devices.
9050 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9052 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9054 Cleaned up genPackBits and genUnpackBits and added two helper
9055 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9056 for literal assignments in genPackBits (thanks to Frieder for
9062 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9064 Fixed bug #748310 (pointer to function type mishandled when the
9065 function name is omitted). Also fixed a SIGSEGV when a function
9066 attribute (reentrant, etc) is used on a non-function or on a
9067 function but misplaced before the parameter list.
9069 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9071 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

9094 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9096 Made the constant following the "interrupt" keyword optional. If
9097 omitted, the function will not automatically be given an entry
9098 in the interrupt vector table (similar to #pragma NOIV, but
9099 less syntacticly kludgy). The interrupt number is also now
9100 range checked. Also fixed a bug in the high order bit example
9107 * support/Util/SDCCerr.c
9108 * support/Util/SDCCerr.h

9118 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9119 be re-activated by defining REDUCE_LITERALS)
9120 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9121 unsigned, but are signed by default
9122 * src/SDCCval.c (constVal): rearranged
9123 * src/SDCCval.c (valMod): preliminary fix
9124 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9576 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
9577 the regression tests I'm not brave enough to enable 245.b, 245.c
9578 * doc/sdccman.lyx: added latex preamble for hyperref package.
9579 Using pdflatex this will give you a hyperlinked pdf file with
9580 bookmarks. (prepend '%' before /usepackage if this breaks something)

9596 Applied patch from bug 737905 (renamed yylineo to mylineno):
9603 * src/pic16/pcode.c: Cleaned warnings
9604 * src/pic16/pcodeflow.c: Cleaned warnings
9605 * src/pic16/pcoderegs.c: Cleaned warnings

9618 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
9620 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
9621 it can be defined with CFLAGS when running configure
9622 * src/SDCCmain.c: fixed compiling + linking with object files
9624 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

9627 added --disable-pic16-port
9628 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9629 * src/SDCCmain.c: linkOptions is changed to set *,
9630 added if/endif conditional macros to remove options help
9631 messages from optionsTable when a port is not configured, added
9632 support for the PIc16 port in the ports table, when executing
9633 the compiler with no port specified on command line, a default
9634 port is selected with the new macro DEFAULT_PORT which is
9635 defined in port.h, in setDefaultOptions() linkOptions is removed
9636 from initialization assignment, since now it is a set,
9637 parseCmdLine uses setParseWithComma for linkOptions, in
9638 linkEdit() linkOptions are accessed with new function indexSet()
9639 which returns the i'th item of a set variable. See SDCCset.c, in
9640 linkEdit() when calling buildCmdLine(), added linkOptions as
9641 last argument. Now users can pass arguments to gplink via the
9642 -Wl option, main() uses pic16glue() to glue up pic16 programs
9643 * src/SDCCpeeph.c: various changes to support pic16

9654 * src/pic16/glue.c: commented out some error producing lines
9655 * src/pic16/main.c: __config directives are commented out to stop
9656 gpasm complaining and test the linkage with gplink, _linkCmd and
9657 _asmCmd changed to be more gplink and gpasm friendly
9658 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9659 produced an error when parsed, peep rule 12 is added to utilize
9660 movff, but it is commented out since the pCode does not support
9661 yet a command with 2 address arguments
9663 2003-05-18 <johan AT balder>
9665 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
9666 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT
9667 2003-05-17 Karl Bongers(apply patches from Martin Helmling)

9690 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
9692 2003-05-11 Borut Razem <borut.razem AT siol.net>
9694 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9695 the path of bin directory, so that PATH is the only env. variable, which has to be set
9696 in case of standard installation.
9697 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

10729 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10730 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10731 following files to include the previous two files: aslink.dsp,
10732 Makefile.aslink, Makefile.bcc, and Makefile.in.
10734 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10735 .adb instead of .cdb
10737 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10739 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10740 value from option --iram-size.
10742 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10744 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10747 2002-09-18 <wiml AT hhhh.org>
10749 * SDCClrange.h: exposed setFromRange() and setToRange()
10750 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10751 packRegsForAccUse() (bug 542397)
10752 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10753 multiple times and emitting the fetch operations more than once
10754 added aopGetUsesAcc() function to allow binary operators to
10755 fetch their operands in the correct order; made genMinus() emit
10756 compact code for X = LITERAL - Y
10758 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10759 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to

10762 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10763 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10766 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10767 Changes to aslink (All the changes are marked with 'JCF'):
10769 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10772 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10773 area BSEG. Also moves, if possible, the DATA area down into the internal
10774 ram so more space is available.
10776 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10779 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10780 not bytes. Function summary() which creates a memory usage summary
10781 file with extension .mem. Reports of overlaping stack and small stack
10782 size. If the space for the stack is less than 16 bytes aslink trows a
10785 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10786 the 8051. Option 'y' for memory summary output file.
10788 Changes to sdcc (All the changes are marked with 'JCF'):
10790 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10792 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10793 overlaying area for it (uses RegBankUsed[4]).
10795 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10796 bank zero as used by default. By default aslink locates the stack
10797 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10798 the creation of the .mem file. Delegates the allocation of data area
10799 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10800 the begining of the stack area to aslink.
10802 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10803 glue() in SDCCglue.c creates an area for it.
10805 2002-09-03 Borut Razem <borut.razem AT siol.net>
10806 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10807 sdcc/src/pic/glue.c:
10808 introduced atexit() handler for teporay files removal in case of
10809 errors, assertions, ...
10811 2002-08-29 Borut Razem <borut.razem AT siol.net>
10812 * sdcc/support/cpp2/auto-host_vc_in.h:
10813 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10814 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10815 Maybe there is a similar problem with BORLANDC? It should be checked!
10817 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10818 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10819 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10820 was not executed, and the compiler (cl) launched a warning:
10821 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10823 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10824 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10826 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10827 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10829 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10830 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10831 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10832 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10833 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10834 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10835 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10836 - added Release configuration in VS projects
10837 - review of compiler an linker options
10838 - VC .exe files are generated in bin_vc directory, not to interfere
10839 with binaries generated from other projects (cygwin, mingw, bcc ...)
10841 * sdcc/src/yacc.dsp: added
10843 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10844 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10845 and insert the version number definitions from .version
10847 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10849 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10850 added - genarate auto-host.h using auto-host_vc_in.h as template
10853 removed from CVS, generated automatically
10855 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10856 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10858 2002-08-11 Borut Razem <borut.razem AT siol.net>
10859 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10861 2002-08-10 Borut Razem <borut.razem AT siol.net>
10862 * src/SDCCmain.c (main):
10863 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10864 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10865 The consequence was that some temporary files were not removed.
10868 unification of code in functions tempfilename() and tempfile():
10869 function tempnam() is defined in Visual Studio 6.0 and .NET
10871 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10873 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10874 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10875 - removed compiler command line option /WX: Treats all warnings as errors
10876 - update a list of source files, included into the project
10878 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10879 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10880 changed project type to Generic Project so that can be correcly converted to VS.NET project
10882 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10884 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10886 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10888 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10889 added return 0 statements after assert() to make compiler happy
10891 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10892 added newline in the def file to keep MSC compiler satisfied
10894 * sdcc/src/z80/gen.c:
10895 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10896 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10897 - solved MSC error in function aopDump()
10899 * sdcc_vc.h: define PREFIX as "\\sdcc"
10901 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

10905 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10906 - Rewrote the register banking algorithm.
10907 - Added pCode live-range analysis to registers (for now, only non-used and
10908 singly-used registers optimized away)
10910 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis

11074 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11076 * sdcc/src/SDCCloop.c:
11077 Previous fix was not good. basic blocks that have "break" or "return" are
11078 not really partof a loop , but live ranges used in these blocks should
11079 be live thru the entire loop, so set partOfLoop but don't add them to
11082 2002-02-21 <johan AT FRIJA>
11084 * src/SDCCcse.c: fixed bug #514308
11086 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
