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

913 * device/examples/main8051.c: deleted - it was removed from CVS
914 24.mar.2000 and after that modified 18.feb.2001, so it reappered

916 * src/SDCCalloc.h: deleted - it was removed from CVS
917 3.feb.2001 and after that modified 18.feb.2001, so it reappered

1155 implemented patch 1120823 Thanks to Willy De la Court (normal
1156 interrupts need an interrupt number now if they are made critical),
1157 and enabled nesting of critical functions though not for gbz80
1158 (genCritical, genEndCritical): added functions
1159 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1160 * src/z80/mappings.i: added "ei" to all mappings

1172 the left operand is shorter than the result (c* = lit-c* + int),
1174 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1177 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1179 * src/.version: increased version number to 2.5.5
1180 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1181 linking is done manually in pic16 port's _linkEdit,
1182 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1183 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1184 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1185 allocate asmop as AOP_ACC,
1186 (aopForRemat): added parameter 'bool result' in function declaration,
1187 (pic16_aopGet): return AOP_ACC when accessing WREG,
1188 (pic16_popGetTempReg): minor modification,

1199 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1200 call to allocReg, not by manually allocating a new one,
1201 (pic16_assignRegisters): now before going through the register
1202 allocating functions mark all registers as free. This eliminates some
1203 side effects resulting from peephole parser done earlier in the backbone
1205 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1263 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1264 which dumps before the function entry point a data byte which represents
1265 the number of the local variables used by the specified function, added
1266 'xinst' for initial support for Extended Instruction Support,
1267 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1268 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1269 port->fun_prefix anymore (may change later),
1270 (genFunction, genEndFunction): do not store/restore local registers for
1271 _main (this should take care the --main-return command line option in
1273 (genOr): removed some legacy pic-port instructions,
1274 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1275 performing operations with SFR's causes data to be written more than
1276 once to each SFR. Perhaps SFRs should be handled in special cases...
1277 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1279 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1280 into account for stack starting position,

1282 --extended or -y for Extended Instruction Support,
1283 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1284 (deassignLRs): *** perhaps the most important change, old 'for' code
1285 (commented out for reference), didn't account for some registers which
1286 were left marked 'not free' after a pointer operation. The change
1287 reduces register usage a lot in some cases
1289 2006-03-04 Borut Razem <borut.razem AT siol.net>

3566 always available in leading double underscore form. The C99 support is
3567 mostly missing, but it's a start.
3568 * support/regression/tests/bug-227710.c: fixed nonconforming use of

3649 * device/lib/printf_large.c: removed inline assembly for portability and
3650 readability. Use printf_fast if speed or size are more important.
3651 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3652 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3654 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3656 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3657 prevent compiler warning
3659 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3661 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3662 moved to level 0 and declared as static. Also they are explicit
3663 placed in access bank. This was necessery because some times they
3664 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3665 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3666 optimizations. Currently only compare to unsigned char is implemented,
3667 * src/pic16/gen.c: added fReturnIdx array,
3668 * (struct resolvedIfx) is moved to gen.h and made public,
3669 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3670 * (aopForSym): added an optimization to directly store in stack of
3671 the operand of a SEND iCode,
3672 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3673 but as registers instead (AOP_REG) using the fReturnIdx array,
3674 * (pic16_freeAsmop): remove the freed register from the
3675 _G.sregsAlloc field,
3676 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3677 a compare of 'WREG',
3678 * (pic16_popGetTempRegCond): changed function prototype, now
3679 function takes also a bitVector argument v which holds the current
3680 set of registers that are allocated for stack access by aopForSym,
3681 registers allocated in aopForSym for accessing stack symbols are not
3682 any more part of the functions usedRegs field,
3683 * (genCall): some times aopOp is called for a stack variable to be
3684 send, aopForSym might perform the push, if this is true make sure
3685 that genCall doesn't push the variable twice by testing _G.resDirect,
3686 * (genFunction): changed testing for unspecified interrupt number
3687 from 256 to INTNO_UNSPEC,
3688 * modified selection scheme of frame pointer generation. Previously
3689 if function did use local registers a frame pointer was generated,
3690 now a frame pointer is generated only if function has arguments
3691 (that need PLUSW2 register access), or has stack arguments, or the
3692 compiler is not instructed to omit the frame pointer,
3693 * (genEndFunction): before restoring local registers that were saved
3694 in the function preamble, also restore the registers that *might*
3695 have been allocated for stack access,
3696 * (genRet): removed some old comments,
3697 * (genCmp, the active (RN's) version): added a call to the
3698 pic16_genCmp_special function to perform the compare with a more
3699 robust and optimized way,
3700 * (genInline): a feature has been added in inline code generation,
3701 which allows a wildcard variable substitution when writing inline
3702 assembly. Code is incomplete and experimental therefore undocumented,
3703 * (genCast): changed order of aopOp for result and right to allow
3704 aopForSym to directly load the result if possible,
3705 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3706 perform an optimized compare on some selected special occasions,
3707 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3708 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3709 generate an IVT any more,
3710 * src/pic16/main.c (pic16_optionsTable): added command line option
3712 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3713 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3715 * src/pic16/NOTES: Raphael Neider added in list of active developers
3716 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3717 jumptable_end to prevent bug #,
3718 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3719 inCond and outCond fields,
3720 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3721 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3722 turn off register spilling,
3723 * (packRegsForOneUse): synced with other ports' versions although it
3724 is not used currently,
3725 * (pic16_packRegisters): added an optimization while reading
3726 structure bitfields, some registers may be saved (malloc code is
3727 decreased by 80 bytes)
3729 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3731 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3732 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3733 this can be optimized more?
3735 2005-03-10 Raphael Neider <rneider AT web.de>
3737 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3738 genNearPointerGet): (hopefully) fixed access to bitfields via
3739 pointers (p->bitN = x; and x = p->bitN; failed)
3741 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

4356 (setFromConditionArgs): friendly operand parser for peephole rules,
4357 (operandBaseName, operandsNotRelated): new peephole condition
4358 "operandsNotRelated" -- similar to "operandsNotSame", but takes
4359 architecture specific register naming into account, handles n-way
4360 comparisons, and supports quoted literals

4371 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4373 Adding support for replacing ljmps with sjmps in jumptables
4374 generated for switch statements. For now you need to set the
4375 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4376 Now 4 algorithms for mcs51 jumptable generation are used:
4377 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4378 addresses loaded pc-relative for up to 112 cases and stack-pushing
4379 target addresses loaded with offset from dptr for up to 256 cases.
4381 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
4382 * src/mcs51/main.c: adapted constants for switch table generation

4406 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
4407 to call when a stack overflow occurs,
4408 * (malloc.h): added CVS Id tag,
4409 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4411 * added libc directory. The current version of LibC contains string
4412 functions, ctype functions and macros and some functions of the
4413 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4414 be extensively tested in the future. Standard disclaimer here.
4415 Library is not automatically build yet. But one can build it by
4416 invoking 'make' inside the libc directory.
4417 * added ADC library under libio. Preliminary version yet.
4419 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

4426 * (genUminusFloat): fixed for pic16, ported code from mcs51,
4427 * (pic16_storeForReturn): optimized return of 0,
4428 * (genCmp): experimental code for new genCmp which uses PIC18's
4429 special compare&skip instructions. Initial tests fail some times
4430 with variables grater than 1 byte in size, so new code is disabled,
4431 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4433 * (genCast): began a fix to optimize the casting of a bit to another
4434 bit, now assigning a bitfield to another bitfield will fail, sorry,
4435 * src/pic16/main.c: disabled the use of lr-support feature,
4436 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
4437 * added some function prototypes, added function _debugf prototype,

4439 bits with offset (case PO_GPR_BIT),
4440 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
4442 * (isBankInstruction): modified to return 0 for no banking instruction,
4443 and 1 for banking instruction,
4444 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4445 caused stop processing pCodes after a inline assembly block,
4446 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4447 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4448 registers when it shouldn't,
4449 * src/pic16/ralloc.c (allocReg): add preliminary support for
4450 supporting a limited set of temporary registers,
4452 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4454 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4455 genDataPointerSet): ensure assignments always copy in MSB to LSB
4457 (loadRegFromAop): recognize CLRH optimization,
4458 (genFunction): optimize RECEIVE iCodes in reentrant functions
4460 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4462 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
4463 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
4465 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

4471 * device/lib/_gptrget.c (_gptrget),
4472 * device/lib/_gptrgetc.c (_gptrgetc),
4473 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
4474 instead of sjmp to ret
4475 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
4476 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
4478 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

7457 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7459 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7460 loaded with the linker search paths (-L arguments) and the libraries
7461 to be linked with the current source (-l arguments). Changes
7462 currently will affect only the pic16 port.
7463 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7464 include path the port specific paths and port specific libraries,
7465 * gplink command now contains the $3 argument,
7466 * src/pic16/device.h,
7467 * src/pic16/device.c,: structure PIC_device is made public and
7468 renamed to PIC16_device, the same for variable Pics which is renamed
7469 to Pics16. Updated all references to them.
7470 * src/pic16/glue.c (pic16glue): corrected bug with code
7471 initialization which bypassed the variable initializations block.
7473 * device/lib/pic16/Makefile.rules: removed --penable-stack from

7481 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
7483 Documenting changes from previous commits.
7484 * configure.in (version 1.56),
7485 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7486 when generating output files to configure the pic16 library,
7487 but now I've commented it out, since gputils aren't installed in the
7488 SF compile farm, so library won't compile
7490 * device/lib/Makefile.in (version 1.56): initially I've added in
7491 target 'all' the prerequestive 'model-pic16' so it compiled the
7492 pic16 library, but now I've commented it out for the same reasons
7494 * added targets 'model-pic16' and 'objects-pic16' to compile the
7496 * added target 'port-specific-objects-pic16' to handle the
7497 generated libraries and copy them into the build/ directory
7498 * added target 'clean-intermediate-pic16' to clean intermediate
7499 files into pic16 directory
7500 * in target 'installdirs' added line to create directory pic16 in
7501 the installation path
7503 * device/include/Makefile.in (version 1.11): in target 'install'
7504 added lines to copy all header files to installation path,
7505 * in target 'installdirs' added line create directory for pic16
7506 headers in the installation path
7508 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

7521 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7522 option so that it actually works. Made it specific to the z80, since
7523 the gbz80 doesn't have these kinds of I/O ports.
7525 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7527 * device/include/z180.h,

7540 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7542 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
7543 changed interrupt vector table generation to only emit declared vectors.
7544 * device/include/Makefile.in: added missing backslash
7545 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
7547 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7549 Mainly changes to support compilation of the device libraries
7550 * src/pic16/device.c: stack is allocated via symbol and not
7551 via literal number. The symbol is placed in the corresponding
7552 position of the data ram
7553 * (pic16_dump_section): relocatable and absolute uninitialized
7554 data are now emitted in sorted order to reduce section naming,
7555 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7556 weren't marked as being in the access bank,
7558 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7560 Added portion of GNU PIC Library under the directory
7561 device/include/pic16 and device/lib/pic16. These files
7562 contain the declarations of SFRs for the PIC18Fxx2 devices.
7563 The directory is initialized via configure from toplevel.
7565 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
7567 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
7568 the spilllocations to be compared correctly
7570 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
7572 * src/SDCCast.c (decorateType): fixed bug introduced today
7574 2004-01-12 Borut Razem <borut.razem AT siol.net>
7576 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

7579 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
7581 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
7582 in simpler and even better code
7584 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
7586 * src/SDCCicode.c (operandOperation): fixed bug #874819

7592 * doc/sdccman.lyx: Moved and added some sections, small changes
7593 all over. Telling LaTeX to be less strict with word spacing
7594 to better keep the right margin. Changed some notes about
7595 maintainance of the ports in section 3.2.1 - is it OK like this?
7597 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7633 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
7634 UPPER for immediate operands,
7635 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7637 * src/pic16/peeph.def: all peepholes with movff are commented out,
7638 because there is a problem in the pcode peep optimizer,
7639 * src/pic16/ralloc.c: the register allocator can now reuse local
7640 function symbols for another function. This saves register usage.
7641 * src/pic16/ralloc.h: added flag isLocal in structure regs,
7643 Added file src/pic16/NOTES with information about program writing on
7644 the current port version.

7653 * src/SDCCmain.c : fixed #872250: -l command line defined library
7654 files are scanned before standard library files
7656 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7673 gen51Code): more efficient parameter receive for --model-large
7676 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7679 * src/z80/main.c: added missed needLinkerScript flags (more than
7680 one port structure defined in these file)
7681 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

7697 needLinkerScript flag
7699 * src/pic16/gen.c (genAddrOf): fixed bug #863624
7700 * src/pic/glue.c: added variable udata_section_name to
7701 override default uninitialized data segment definition for
7702 devices only with SHAREBANK memory (reported from Erik Epetrich)
7703 * (pic14emitOverlay): modified to emit a commented overlay segment
7704 directive when no overlay data exist
7705 * (picglue): modified to emit uninitialized data segment
7706 according to udata_section_name

7712 * src/pic16/main.c: added $l in _asmCmd, changed extension for
7713 object file from '.rel' to '.o' in port->linker structure,
7714 changed size of fptr from 2 to 3 in port structure
7716 2004-01-07 Borut Razem <borut.razem AT siol.net>
7718 * support/scripts/sdcc.nsi: update PATH
7719 * support/scripts/sdcc.ico: craeted
7721 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>
7723 * device/include/Makefile.in: fix install
7724 * doc/Makefile: fix install
7726 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7728 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
7730 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

7732 include information about variables allocated to the overlay
7735 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7737 * as/mcs51/lkmain.c: Help about -Y option

7749 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7751 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7752 (default behaviour).
7754 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7756 A python script to validate compiler diagnostic messages. It can be
7757 used to verify that sdcc complains about bad c source code and
7758 gives a good location of the error.
7759 * support/valdiag/Makefile,
7760 * support/valdiag/valdiag.py,
7761 * support/valdiag/tests/*
7763 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7765 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

7774 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7776 * src/common.h: added ifndef/define/endif macros
7777 around the header file.
7778 Bug reported from Jesus Calvino-Fraga
7780 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7782 * sdcc.spec: updated
7783 * device/include/Makefile.in: don't install CVS directories
7784 * device/lib/Makefile.in: added removal of CVS directories after install
7785 * doc/Makefile: fixed install, added local_icons
7786 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7787 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7788 * src/ds390/gen.c (genRightShift): fixed bug #870788
7789 * src/SDCCast.c (decorateType): fixed bug #870781
7791 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7793 PIC16 port related changes:
7794 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7795 added variable stackPos,
7797 * gen.c: genCall, assignResultValue: added support for
7798 pushing/retrieving function parameters to/from stack,
7799 genFunction,genEndFunction: setup stack frame for the
7801 genAddrOf: will be changed according to bug 863624
7803 * added files genutils.c and genutils.h which contain gen*
7804 debugged and optimised functions extracted from gen.c
7806 * glue.c: added variable 'externs' which holds extern symbols,
7807 pic16emitRegularMap: is modified to properly handle relocatable
7808 symbols under the new scheme,
7809 pic16createInterruptVect: is modified
7810 pic16printPublics: is modified to emit 'global' assembler directives,
7811 added pic16_printExterns to print extern symbols,
7812 pic16glue: initializes stack/frame pointer in the beginning of
7813 the assembly output. Temporary hack, will be corrected later,
7814 because gplink yet does not support stack and SDCC does not
7815 yet support a type of crt0.o object to create the final binary.
7817 * Removed many lines that contain 8051 legacy code.
7818 * The code is finally placed under a 'code' directive.
7819 * Added port specific options.
7821 * _process_pragma: simplified since now we do not need *special*
7822 include file to define SFR registers. But a separate header
7823 will be needed. This will be developed later.
7824 * _pic16_parseOptions: added, parses port specific options:
7825 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7826 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7827 --preplace-udata-with=
7829 * _pic16_setDefaultOptions: modified to initialize section names,
7830 but hack is temporarly out of order since it needs improvement.
7831 * _pic16_genAssemblerPreamble: configuration words are emitted by
7832 their address instead of their name. This part is incomplete and
7833 supports only the 18Fxx2 devices. Other devices will emit an error
7834 during assembly since they do not contain the same set of config
7836 * _pic16_genIVT: is modified,
7838 * pcode.c: added definitions for some hardware registers that are needed
7840 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7841 All PCI entries are updated. Now LFSR is supported.
7842 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7843 * added pic16_newpCodeOpLit2 to support instructions with
7844 two literal arguments
7845 * pic16_pCode2str: corrected code that emits assembler instructions
7846 with two literal operands and those that have an access bit modifier
7847 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7848 this fixes a bug which caused some labels to be lost, when an
7849 assembler directive was added, i.e. banksel,
7850 * pic16_FixRegisterBanking: improved logic that causes the insertion
7852 * InlineFunction: functions that are called once, are not any more
7853 inlined. This can be a port option in the future,
7855 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7857 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7858 hold the corresponding uninitialized symbols,
7859 * pic16_allocProcessorRegister: registers have explicit marked the
7861 * pic16_allocInternalRegister: registers are explicit marked as
7863 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7864 processing list, so bit registers were lost,
7867 * ralloc.h: added field 'accessBank' and original symbol operand
7868 in register definition,
7869 * removed the field isMapped from register definition,
7871 ** Several functions have been removed from various sources:
7872 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7873 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7874 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7875 pic16_assignRelocatableRegisters
7877 ** others have been introduced:
7878 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7879 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7881 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7883 * support/scripts/inc2h.pl: changed definition of BIT_AT
7884 to emit 'sbit at' instead of 'bit at'. This was a request.
7886 PIC16 port related preliminary changes:
7887 * gen.c: prefixed function popRegFromString with
7888 pic16_ and all references to it corrected
7889 * pcode.c: all pic16_pc_* hardware registers prefixed
7890 with underscore (_),
7891 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7892 * ralloc.c: newReg(): when register is REG_SFR then
7893 set address to rIdx,
7894 pic16_allocProcessorRegister(): marks register wasUsed=0
7895 pic16_writeUsedRegs(): added a call to assign processor
7896 registers via pic16_assignFixedRegisters
7898 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7900 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7901 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7902 variables in unused register banks. Also the SSEG is placed
7903 wherever there is enough space for it, and IDATA can be anywhere
7904 in internal RAM. For now compile using -Wl-Y[stack_size].
7905 The mem file is different for this option as well, since it
7906 makes no sense of talking about DSEG lenght.
7908 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7910 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7911 in certain cases, e.g. when ROM assignment, patch provided
7912 from Albert den Haan.
7914 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>
7916 Many signedness and type propagation fixes:
7917 * src/SDCCicode.c: made geniCodeCast() static
7918 replaced SPEC_ by IS_ (cosmetic)
7919 (operandOperation): fixed div and mod operation
7920 (usualBinaryConversions): added support for promotion of char
7921 (geniCodeMultiply): replaced (unsigned long) by (TYPE_UDWORD)
7922 (geniCodeDivision): replaced (unsigned long) by (TYPE_UDWORD)
7923 (geniCodeAdd): an array index will stay unsigned, even if promoted

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

8930 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8932 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
8933 these ports have their own __sdcc_external_start()
8935 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8937 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8938 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8939 type for bits was changed. It resulted in bit variables becoming
8940 global, which is not permitted in PIC 14 assembly output.
8942 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8944 * doc/sdccman.lyx: various additions and updates. Rearranged sections
8946 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8948 Z80 and MCS51 linkers complaint if a public symbol is defined
8949 in more than one library module:

8957 A few small changes that speed up the peephole optimizer.
8961 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8963 Try to make the peephole optimizer smarter by maintaining
8964 an association between the assembly source code and the
8965 iCodes that originated them. Put this information to use
8966 with a new peephole rule condition "notVolatile" so that
8967 the rules can be aggressive yet still safe.
8972 * src/mcs51/peeph.def
8974 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8978 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8979 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8980 if the left or right operand symbols have the accuse flag set.
8982 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8984 Changed the type of the result of the ! (NOT) operator to char;
8985 previously it returned the same type as the source. This allows
8986 us to eliminate all the genFloatNot functions (all of its target
8987 implementations were very buggy) since !float can use the same
8990 * src/SDCCicode.c (ast2iCode): ! returns char
8991 * src/mcs51/gen.c (genNot, genNotFloat),
8992 * src/ds390/gen.c (genNot, genNotFloat),
8993 * src/z80/gen.c (genNot, genNotFloat),
8994 * src/pic/gen.c (genNot, genNotFloat),
8995 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

8999 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9000 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9001 during interrupts. Ensure WSAVE is located at a shared bank address.
9002 2. Fixed page selection in some places
9003 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9004 the registers name strings.
9005 4. Fixed "signed / unsigned compare" compiler warnings.
9006 5. The PIC port manages its own allocation of the general purpose
9007 registers, but makes no attempt to reuse them. As a result when
9008 compiling it soon runs out of general purpose registers. Some
9009 additional code was added to the files pcode.c and device.c to walk
9010 through the function call tree and rename the registers so that they
9020 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

9027 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9029 Made bitfield a distinct type from bit so that bitfields
9030 convert as per ANSI C and bits retain their traditional
9031 boolean style behaviour. Implemented bitfield support in
9039 * src/ds390/gen.c: bit v bitfield split
9040 * src/z80/gen.c: New support for bitfields
9041 * support/regression/tests/bitfields.c: reenabled z80,
9044 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9046 Rules 246.x, 247.x relate to bitfields, the others speed up
9047 access to xdata mapped I/O devices.
9049 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9051 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9053 Cleaned up genPackBits and genUnpackBits and added two helper
9054 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9055 for literal assignments in genPackBits (thanks to Frieder for
9061 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9063 Fixed bug #748310 (pointer to function type mishandled when the
9064 function name is omitted). Also fixed a SIGSEGV when a function
9065 attribute (reentrant, etc) is used on a non-function or on a
9066 function but misplaced before the parameter list.
9068 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9070 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

9093 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9095 Made the constant following the "interrupt" keyword optional. If
9096 omitted, the function will not automatically be given an entry
9097 in the interrupt vector table (similar to #pragma NOIV, but
9098 less syntacticly kludgy). The interrupt number is also now
9099 range checked. Also fixed a bug in the high order bit example

9120 unsigned, but are signed by default
9121 * src/SDCCval.c (constVal): rearranged
9122 * src/SDCCval.c (valMod): preliminary fix
9123 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9575 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
9576 the regression tests I'm not brave enough to enable 245.b, 245.c
9577 * doc/sdccman.lyx: added latex preamble for hyperref package.
9578 Using pdflatex this will give you a hyperlinked pdf file with
9579 bookmarks. (prepend '%' before /usepackage if this breaks something)

9595 Applied patch from bug 737905 (renamed yylineo to mylineno):
9602 * src/pic16/pcode.c: Cleaned warnings
9603 * src/pic16/pcodeflow.c: Cleaned warnings
9604 * src/pic16/pcoderegs.c: Cleaned warnings

9617 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
9619 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
9620 it can be defined with CFLAGS when running configure
9621 * src/SDCCmain.c: fixed compiling + linking with object files
9623 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

9626 added --disable-pic16-port
9627 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9628 * src/SDCCmain.c: linkOptions is changed to set *,
9629 added if/endif conditional macros to remove options help
9630 messages from optionsTable when a port is not configured, added
9631 support for the PIc16 port in the ports table, when executing
9632 the compiler with no port specified on command line, a default
9633 port is selected with the new macro DEFAULT_PORT which is
9634 defined in port.h, in setDefaultOptions() linkOptions is removed
9635 from initialization assignment, since now it is a set,
9636 parseCmdLine uses setParseWithComma for linkOptions, in
9637 linkEdit() linkOptions are accessed with new function indexSet()
9638 which returns the i'th item of a set variable. See SDCCset.c, in
9639 linkEdit() when calling buildCmdLine(), added linkOptions as
9640 last argument. Now users can pass arguments to gplink via the
9641 -Wl option, main() uses pic16glue() to glue up pic16 programs
9642 * src/SDCCpeeph.c: various changes to support pic16

9653 * src/pic16/glue.c: commented out some error producing lines
9654 * src/pic16/main.c: __config directives are commented out to stop
9655 gpasm complaining and test the linkage with gplink, _linkCmd and
9656 _asmCmd changed to be more gplink and gpasm friendly
9657 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9658 produced an error when parsed, peep rule 12 is added to utilize
9659 movff, but it is commented out since the pCode does not support
9660 yet a command with 2 address arguments
9662 2003-05-18 <johan AT balder>
9664 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
9665 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT
9666 2003-05-17 Karl Bongers(apply patches from Martin Helmling)

9689 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
9691 2003-05-11 Borut Razem <borut.razem AT siol.net>
9693 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9694 the path of bin directory, so that PATH is the only env. variable, which has to be set
9695 in case of standard installation.
9696 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

10728 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10729 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10730 following files to include the previous two files: aslink.dsp,
10731 Makefile.aslink, Makefile.bcc, and Makefile.in.
10733 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10734 .adb instead of .cdb
10736 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10738 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10739 value from option --iram-size.
10741 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10743 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10746 2002-09-18 <wiml AT hhhh.org>
10748 * SDCClrange.h: exposed setFromRange() and setToRange()
10749 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10750 packRegsForAccUse() (bug 542397)
10751 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10752 multiple times and emitting the fetch operations more than once
10753 added aopGetUsesAcc() function to allow binary operators to
10754 fetch their operands in the correct order; made genMinus() emit
10755 compact code for X = LITERAL - Y
10757 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10758 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to

10765 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10766 Changes to aslink (All the changes are marked with 'JCF'):
10768 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10771 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10772 area BSEG. Also moves, if possible, the DATA area down into the internal
10773 ram so more space is available.
10775 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10778 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10779 not bytes. Function summary() which creates a memory usage summary
10780 file with extension .mem. Reports of overlaping stack and small stack
10781 size. If the space for the stack is less than 16 bytes aslink trows a
10784 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10785 the 8051. Option 'y' for memory summary output file.
10787 Changes to sdcc (All the changes are marked with 'JCF'):
10789 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10791 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10792 overlaying area for it (uses RegBankUsed[4]).
10794 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10795 bank zero as used by default. By default aslink locates the stack
10796 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10797 the creation of the .mem file. Delegates the allocation of data area
10798 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10799 the begining of the stack area to aslink.
10801 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10802 glue() in SDCCglue.c creates an area for it.
10804 2002-09-03 Borut Razem <borut.razem AT siol.net>
10805 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10806 sdcc/src/pic/glue.c:
10807 introduced atexit() handler for teporay files removal in case of
10808 errors, assertions, ...
10810 2002-08-29 Borut Razem <borut.razem AT siol.net>
10811 * sdcc/support/cpp2/auto-host_vc_in.h:
10812 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10813 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10814 Maybe there is a similar problem with BORLANDC? It should be checked!
10816 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10817 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10818 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10819 was not executed, and the compiler (cl) launched a warning:
10820 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10822 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10823 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10825 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10826 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10828 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10829 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10830 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10831 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10832 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10833 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10834 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10835 - added Release configuration in VS projects
10836 - review of compiler an linker options
10837 - VC .exe files are generated in bin_vc directory, not to interfere
10838 with binaries generated from other projects (cygwin, mingw, bcc ...)
10840 * sdcc/src/yacc.dsp: added
10842 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10843 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10844 and insert the version number definitions from .version
10846 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10848 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10849 added - genarate auto-host.h using auto-host_vc_in.h as template
10852 removed from CVS, generated automatically
10854 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10855 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10857 2002-08-11 Borut Razem <borut.razem AT siol.net>
10858 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10860 2002-08-10 Borut Razem <borut.razem AT siol.net>
10861 * src/SDCCmain.c (main):
10862 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10863 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10864 The consequence was that some temporary files were not removed.
10867 unification of code in functions tempfilename() and tempfile():
10868 function tempnam() is defined in Visual Studio 6.0 and .NET
10870 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10872 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10873 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10874 - removed compiler command line option /WX: Treats all warnings as errors
10875 - update a list of source files, included into the project
10877 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10878 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10879 changed project type to Generic Project so that can be correcly converted to VS.NET project
10881 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10883 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10885 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10887 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10888 added return 0 statements after assert() to make compiler happy
10890 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10891 added newline in the def file to keep MSC compiler satisfied
10893 * sdcc/src/z80/gen.c:
10894 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10895 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10896 - solved MSC error in function aopDump()
10898 * sdcc_vc.h: define PREFIX as "\\sdcc"
10900 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10901 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10904 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10905 - Rewrote the register banking algorithm.
10906 - Added pCode live-range analysis to registers (for now, only non-used and
10907 singly-used registers optimized away)
10909 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis

10938 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10940 2002-03-28 Johan Knol <johan AT balder>
10942 * src/SDCCval.c: fixed bug #532436
10944 2002-03-14 Scott Dattalo <scott AT dattalo.com>

11073 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11075 * sdcc/src/SDCCloop.c:
11076 Previous fix was not good. basic blocks that have "break" or "return" are
11077 not really partof a loop , but live ranges used in these blocks should
11078 be live thru the entire loop, so set partOfLoop but don't add them to
11081 2002-02-21 <johan AT FRIJA>
11083 * src/SDCCcse.c: fixed bug #514308
11085 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
