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

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

1162 implemented patch 1120823 Thanks to Willy De la Court (normal
1163 interrupts need an interrupt number now if they are made critical),
1164 and enabled nesting of critical functions though not for gbz80
1165 (genCritical, genEndCritical): added functions
1166 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1167 * src/z80/mappings.i: added "ei" to all mappings

1179 the left operand is shorter than the result (c* = lit-c* + int),
1181 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1184 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1186 * src/.version: increased version number to 2.5.5
1187 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1188 linking is done manually in pic16 port's _linkEdit,
1189 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1190 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1191 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1192 allocate asmop as AOP_ACC,
1193 (aopForRemat): added parameter 'bool result' in function declaration,
1194 (pic16_aopGet): return AOP_ACC when accessing WREG,
1195 (pic16_popGetTempReg): minor modification,

1206 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1207 call to allocReg, not by manually allocating a new one,
1208 (pic16_assignRegisters): now before going through the register
1209 allocating functions mark all registers as free. This eliminates some
1210 side effects resulting from peephole parser done earlier in the backbone
1212 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1270 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1271 which dumps before the function entry point a data byte which represents
1272 the number of the local variables used by the specified function, added
1273 'xinst' for initial support for Extended Instruction Support,
1274 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1275 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1276 port->fun_prefix anymore (may change later),
1277 (genFunction, genEndFunction): do not store/restore local registers for
1278 _main (this should take care the --main-return command line option in
1280 (genOr): removed some legacy pic-port instructions,
1281 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1282 performing operations with SFR's causes data to be written more than
1283 once to each SFR. Perhaps SFRs should be handled in special cases...
1284 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1286 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1287 into account for stack starting position,

1289 --extended or -y for Extended Instruction Support,
1290 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1291 (deassignLRs): *** perhaps the most important change, old 'for' code
1292 (commented out for reference), didn't account for some registers which
1293 were left marked 'not free' after a pointer operation. The change
1294 reduces register usage a lot in some cases
1296 2006-03-04 Borut Razem <borut.razem AT siol.net>

3571 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3572 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3573 always available in leading double underscore form. The C99 support is
3574 mostly missing, but it's a start.

3656 * device/lib/printf_large.c: removed inline assembly for portability and
3657 readability. Use printf_fast if speed or size are more important.
3658 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3659 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3661 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3663 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3664 prevent compiler warning
3666 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3668 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3669 moved to level 0 and declared as static. Also they are explicit
3670 placed in access bank. This was necessery because some times they
3671 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3672 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3673 optimizations. Currently only compare to unsigned char is implemented,
3674 * src/pic16/gen.c: added fReturnIdx array,
3675 * (struct resolvedIfx) is moved to gen.h and made public,
3676 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3677 * (aopForSym): added an optimization to directly store in stack of
3678 the operand of a SEND iCode,
3679 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3680 but as registers instead (AOP_REG) using the fReturnIdx array,
3681 * (pic16_freeAsmop): remove the freed register from the
3682 _G.sregsAlloc field,
3683 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3684 a compare of 'WREG',
3685 * (pic16_popGetTempRegCond): changed function prototype, now
3686 function takes also a bitVector argument v which holds the current
3687 set of registers that are allocated for stack access by aopForSym,
3688 registers allocated in aopForSym for accessing stack symbols are not
3689 any more part of the functions usedRegs field,
3690 * (genCall): some times aopOp is called for a stack variable to be
3691 send, aopForSym might perform the push, if this is true make sure
3692 that genCall doesn't push the variable twice by testing _G.resDirect,
3693 * (genFunction): changed testing for unspecified interrupt number
3694 from 256 to INTNO_UNSPEC,
3695 * modified selection scheme of frame pointer generation. Previously
3696 if function did use local registers a frame pointer was generated,
3697 now a frame pointer is generated only if function has arguments
3698 (that need PLUSW2 register access), or has stack arguments, or the
3699 compiler is not instructed to omit the frame pointer,
3700 * (genEndFunction): before restoring local registers that were saved
3701 in the function preamble, also restore the registers that *might*
3702 have been allocated for stack access,
3703 * (genRet): removed some old comments,
3704 * (genCmp, the active (RN's) version): added a call to the
3705 pic16_genCmp_special function to perform the compare with a more
3706 robust and optimized way,
3707 * (genInline): a feature has been added in inline code generation,
3708 which allows a wildcard variable substitution when writing inline
3709 assembly. Code is incomplete and experimental therefore undocumented,
3710 * (genCast): changed order of aopOp for result and right to allow
3711 aopForSym to directly load the result if possible,
3712 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3713 perform an optimized compare on some selected special occasions,
3714 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3715 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3716 generate an IVT any more,
3717 * src/pic16/main.c (pic16_optionsTable): added command line option
3719 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3720 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3722 * src/pic16/NOTES: Raphael Neider added in list of active developers
3723 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3724 jumptable_end to prevent bug #,
3725 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3726 inCond and outCond fields,
3727 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3728 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3729 turn off register spilling,
3730 * (packRegsForOneUse): synced with other ports' versions although it
3731 is not used currently,
3732 * (pic16_packRegisters): added an optimization while reading
3733 structure bitfields, some registers may be saved (malloc code is
3734 decreased by 80 bytes)
3736 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3738 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3739 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3740 this can be optimized more?
3742 2005-03-10 Raphael Neider <rneider AT web.de>
3744 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3745 genNearPointerGet): (hopefully) fixed access to bitfields via
3746 pointers (p->bitN = x; and x = p->bitN; failed)

4378 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4380 Adding support for replacing ljmps with sjmps in jumptables
4381 generated for switch statements. For now you need to set the
4382 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4383 Now 4 algorithms for mcs51 jumptable generation are used:
4384 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4385 addresses loaded pc-relative for up to 112 cases and stack-pushing
4386 target addresses loaded with offset from dptr for up to 256 cases.
4388 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
4389 * src/mcs51/main.c: adapted constants for switch table generation

4413 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
4414 to call when a stack overflow occurs,
4415 * (malloc.h): added CVS Id tag,
4416 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4418 * added libc directory. The current version of LibC contains string
4419 functions, ctype functions and macros and some functions of the
4420 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4421 be extensively tested in the future. Standard disclaimer here.
4422 Library is not automatically build yet. But one can build it by
4423 invoking 'make' inside the libc directory.
4424 * added ADC library under libio. Preliminary version yet.
4426 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

4433 * (genUminusFloat): fixed for pic16, ported code from mcs51,
4434 * (pic16_storeForReturn): optimized return of 0,
4435 * (genCmp): experimental code for new genCmp which uses PIC18's
4436 special compare&skip instructions. Initial tests fail some times
4437 with variables grater than 1 byte in size, so new code is disabled,
4438 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4440 * (genCast): began a fix to optimize the casting of a bit to another
4441 bit, now assigning a bitfield to another bitfield will fail, sorry,
4442 * src/pic16/main.c: disabled the use of lr-support feature,
4443 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
4444 * added some function prototypes, added function _debugf prototype,

4446 bits with offset (case PO_GPR_BIT),
4447 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
4449 * (isBankInstruction): modified to return 0 for no banking instruction,
4450 and 1 for banking instruction,
4451 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4452 caused stop processing pCodes after a inline assembly block,
4453 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4454 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4455 registers when it shouldn't,
4456 * src/pic16/ralloc.c (allocReg): add preliminary support for
4457 supporting a limited set of temporary registers,
4459 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4461 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4462 genDataPointerSet): ensure assignments always copy in MSB to LSB
4464 (loadRegFromAop): recognize CLRH optimization,
4465 (genFunction): optimize RECEIVE iCodes in reentrant functions
4467 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4469 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
4470 --out-fmt-s19 turning into --out-fmt-elf if s19 was already

4483 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
4485 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

7464 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7466 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7467 loaded with the linker search paths (-L arguments) and the libraries
7468 to be linked with the current source (-l arguments). Changes
7469 currently will affect only the pic16 port.
7470 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7471 include path the port specific paths and port specific libraries,
7472 * gplink command now contains the $3 argument,
7473 * src/pic16/device.h,
7474 * src/pic16/device.c,: structure PIC_device is made public and
7475 renamed to PIC16_device, the same for variable Pics which is renamed
7476 to Pics16. Updated all references to them.
7477 * src/pic16/glue.c (pic16glue): corrected bug with code
7478 initialization which bypassed the variable initializations block.

7488 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
7490 Documenting changes from previous commits.
7491 * configure.in (version 1.56),
7492 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7493 when generating output files to configure the pic16 library,
7494 but now I've commented it out, since gputils aren't installed in the
7495 SF compile farm, so library won't compile
7497 * device/lib/Makefile.in (version 1.56): initially I've added in
7498 target 'all' the prerequestive 'model-pic16' so it compiled the
7499 pic16 library, but now I've commented it out for the same reasons
7501 * added targets 'model-pic16' and 'objects-pic16' to compile the
7503 * added target 'port-specific-objects-pic16' to handle the
7504 generated libraries and copy them into the build/ directory
7505 * added target 'clean-intermediate-pic16' to clean intermediate
7506 files into pic16 directory
7507 * in target 'installdirs' added line to create directory pic16 in
7508 the installation path
7510 * device/include/Makefile.in (version 1.11): in target 'install'
7511 added lines to copy all header files to installation path,
7512 * in target 'installdirs' added line create directory for pic16
7513 headers in the installation path
7515 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

7528 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7529 option so that it actually works. Made it specific to the z80, since
7530 the gbz80 doesn't have these kinds of I/O ports.
7532 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7534 * device/include/z180.h,

7547 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7549 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
7550 changed interrupt vector table generation to only emit declared vectors.
7551 * device/include/Makefile.in: added missing backslash
7552 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
7554 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7556 Mainly changes to support compilation of the device libraries
7557 * src/pic16/device.c: stack is allocated via symbol and not
7558 via literal number. The symbol is placed in the corresponding
7559 position of the data ram
7560 * (pic16_dump_section): relocatable and absolute uninitialized
7561 data are now emitted in sorted order to reduce section naming,
7562 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7563 weren't marked as being in the access bank,
7565 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7567 Added portion of GNU PIC Library under the directory
7568 device/include/pic16 and device/lib/pic16. These files
7569 contain the declarations of SFRs for the PIC18Fxx2 devices.
7570 The directory is initialized via configure from toplevel.
7572 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
7574 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
7575 the spilllocations to be compared correctly
7577 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
7579 * src/SDCCast.c (decorateType): fixed bug introduced today
7581 2004-01-12 Borut Razem <borut.razem AT siol.net>
7583 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

7586 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
7588 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
7589 in simpler and even better code
7591 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
7593 * src/SDCCicode.c (operandOperation): fixed bug #874819

7599 * doc/sdccman.lyx: Moved and added some sections, small changes
7600 all over. Telling LaTeX to be less strict with word spacing
7601 to better keep the right margin. Changed some notes about
7602 maintainance of the ports in section 3.2.1 - is it OK like this?
7604 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
7606 SDCC source changes:
7607 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

7640 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
7641 UPPER for immediate operands,
7642 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7644 * src/pic16/peeph.def: all peepholes with movff are commented out,
7645 because there is a problem in the pcode peep optimizer,
7646 * src/pic16/ralloc.c: the register allocator can now reuse local
7647 function symbols for another function. This saves register usage.
7648 * src/pic16/ralloc.h: added flag isLocal in structure regs,
7650 Added file src/pic16/NOTES with information about program writing on
7651 the current port version.

7660 * src/SDCCmain.c : fixed #872250: -l command line defined library
7661 files are scanned before standard library files
7663 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7680 gen51Code): more efficient parameter receive for --model-large
7683 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7686 * src/z80/main.c: added missed needLinkerScript flags (more than
7687 one port structure defined in these file)
7688 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

7704 needLinkerScript flag
7706 * src/pic16/gen.c (genAddrOf): fixed bug #863624
7707 * src/pic/glue.c: added variable udata_section_name to
7708 override default uninitialized data segment definition for
7709 devices only with SHAREBANK memory (reported from Erik Epetrich)
7710 * (pic14emitOverlay): modified to emit a commented overlay segment
7711 directive when no overlay data exist
7712 * (picglue): modified to emit uninitialized data segment
7713 according to udata_section_name

7718 arguments via -W option
7719 * src/pic16/main.c: added $l in _asmCmd, changed extension for
7720 object file from '.rel' to '.o' in port->linker structure,
7721 changed size of fptr from 2 to 3 in port structure
7723 2004-01-07 Borut Razem <borut.razem AT siol.net>
7725 * support/scripts/sdcc.nsi: update PATH
7726 * support/scripts/sdcc.ico: craeted
7728 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>
7730 * device/include/Makefile.in: fix install
7731 * doc/Makefile: fix install
7733 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7735 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
7737 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

7739 include information about variables allocated to the overlay
7742 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7744 * as/mcs51/lkmain.c: Help about -Y option

7756 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7758 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7759 (default behaviour).
7761 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7763 A python script to validate compiler diagnostic messages. It can be
7764 used to verify that sdcc complains about bad c source code and
7765 gives a good location of the error.
7766 * support/valdiag/Makefile,
7767 * support/valdiag/valdiag.py,
7768 * support/valdiag/tests/*
7770 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7772 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
7773 * src/SDCCsymt.c (newEnumType),

7781 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7783 * src/common.h: added ifndef/define/endif macros
7784 around the header file.
7785 Bug reported from Jesus Calvino-Fraga
7787 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7789 * sdcc.spec: updated
7790 * device/include/Makefile.in: don't install CVS directories
7791 * device/lib/Makefile.in: added removal of CVS directories after install
7792 * doc/Makefile: fixed install, added local_icons
7793 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7794 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7795 * src/ds390/gen.c (genRightShift): fixed bug #870788
7796 * src/SDCCast.c (decorateType): fixed bug #870781
7798 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7800 PIC16 port related changes:
7801 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7802 added variable stackPos,
7804 * gen.c: genCall, assignResultValue: added support for
7805 pushing/retrieving function parameters to/from stack,
7806 genFunction,genEndFunction: setup stack frame for the
7808 genAddrOf: will be changed according to bug 863624
7810 * added files genutils.c and genutils.h which contain gen*
7811 debugged and optimised functions extracted from gen.c
7813 * glue.c: added variable 'externs' which holds extern symbols,
7814 pic16emitRegularMap: is modified to properly handle relocatable
7815 symbols under the new scheme,
7816 pic16createInterruptVect: is modified
7817 pic16printPublics: is modified to emit 'global' assembler directives,
7818 added pic16_printExterns to print extern symbols,
7819 pic16glue: initializes stack/frame pointer in the beginning of
7820 the assembly output. Temporary hack, will be corrected later,
7821 because gplink yet does not support stack and SDCC does not
7822 yet support a type of crt0.o object to create the final binary.
7824 * Removed many lines that contain 8051 legacy code.
7825 * The code is finally placed under a 'code' directive.
7826 * Added port specific options.
7828 * _process_pragma: simplified since now we do not need *special*
7829 include file to define SFR registers. But a separate header
7830 will be needed. This will be developed later.
7831 * _pic16_parseOptions: added, parses port specific options:
7832 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7833 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7834 --preplace-udata-with=
7836 * _pic16_setDefaultOptions: modified to initialize section names,
7837 but hack is temporarly out of order since it needs improvement.
7838 * _pic16_genAssemblerPreamble: configuration words are emitted by
7839 their address instead of their name. This part is incomplete and
7840 supports only the 18Fxx2 devices. Other devices will emit an error
7841 during assembly since they do not contain the same set of config
7843 * _pic16_genIVT: is modified,
7845 * pcode.c: added definitions for some hardware registers that are needed
7847 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7848 All PCI entries are updated. Now LFSR is supported.
7849 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7850 * added pic16_newpCodeOpLit2 to support instructions with
7851 two literal arguments
7852 * pic16_pCode2str: corrected code that emits assembler instructions
7853 with two literal operands and those that have an access bit modifier
7854 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7855 this fixes a bug which caused some labels to be lost, when an
7856 assembler directive was added, i.e. banksel,
7857 * pic16_FixRegisterBanking: improved logic that causes the insertion
7859 * InlineFunction: functions that are called once, are not any more
7860 inlined. This can be a port option in the future,
7862 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7864 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7865 hold the corresponding uninitialized symbols,
7866 * pic16_allocProcessorRegister: registers have explicit marked the
7868 * pic16_allocInternalRegister: registers are explicit marked as
7870 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7871 processing list, so bit registers were lost,
7874 * ralloc.h: added field 'accessBank' and original symbol operand
7875 in register definition,
7876 * removed the field isMapped from register definition,
7878 ** Several functions have been removed from various sources:
7879 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7880 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7881 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7882 pic16_assignRelocatableRegisters
7884 ** others have been introduced:
7885 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7886 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7888 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7890 * support/scripts/inc2h.pl: changed definition of BIT_AT
7891 to emit 'sbit at' instead of 'bit at'. This was a request.
7893 PIC16 port related preliminary changes:
7894 * gen.c: prefixed function popRegFromString with
7895 pic16_ and all references to it corrected
7896 * pcode.c: all pic16_pc_* hardware registers prefixed
7897 with underscore (_),
7898 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7899 * ralloc.c: newReg(): when register is REG_SFR then
7900 set address to rIdx,
7901 pic16_allocProcessorRegister(): marks register wasUsed=0
7902 pic16_writeUsedRegs(): added a call to assign processor
7903 registers via pic16_assignFixedRegisters
7905 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7907 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7908 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7909 variables in unused register banks. Also the SSEG is placed
7910 wherever there is enough space for it, and IDATA can be anywhere
7911 in internal RAM. For now compile using -Wl-Y[stack_size].
7912 The mem file is different for this option as well, since it
7913 makes no sense of talking about DSEG lenght.
7915 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7917 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7918 in certain cases, e.g. when ROM assignment, patch provided
7919 from Albert den Haan.
7921 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>
7923 Many signedness and type propagation fixes:
7924 * src/SDCCicode.c: made geniCodeCast() static
7925 replaced SPEC_ by IS_ (cosmetic)
7926 (operandOperation): fixed div and mod operation
7927 (usualBinaryConversions): added support for promotion of char
7928 (geniCodeMultiply): replaced (unsigned long) by (TYPE_UDWORD)

8924 fetching of the pointer
8925 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8926 copied from genNearPointerSet()
8927 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8928 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
8929 If they pop r0/r1 they must be called in the opposite order than aopOp().
8930 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
8931 (resp. --stack-auto), prepared for --xstack

8940 these ports have their own __sdcc_external_start()
8942 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8944 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8945 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8946 type for bits was changed. It resulted in bit variables becoming
8947 global, which is not permitted in PIC 14 assembly output.
8949 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8951 * doc/sdccman.lyx: various additions and updates. Rearranged sections
8953 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8955 Z80 and MCS51 linkers complaint if a public symbol is defined

8964 A few small changes that speed up the peephole optimizer.
8968 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8970 Try to make the peephole optimizer smarter by maintaining
8971 an association between the assembly source code and the
8972 iCodes that originated them. Put this information to use
8973 with a new peephole rule condition "notVolatile" so that
8974 the rules can be aggressive yet still safe.
8979 * src/mcs51/peeph.def
8981 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8985 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8986 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8987 if the left or right operand symbols have the accuse flag set.
8989 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8991 Changed the type of the result of the ! (NOT) operator to char;
8992 previously it returned the same type as the source. This allows
8993 us to eliminate all the genFloatNot functions (all of its target
8994 implementations were very buggy) since !float can use the same
8997 * src/SDCCicode.c (ast2iCode): ! returns char
8998 * src/mcs51/gen.c (genNot, genNotFloat),
8999 * src/ds390/gen.c (genNot, genNotFloat),
9000 * src/z80/gen.c (genNot, genNotFloat),
9001 * src/pic/gen.c (genNot, genNotFloat),
9002 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

9006 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9007 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9008 during interrupts. Ensure WSAVE is located at a shared bank address.
9009 2. Fixed page selection in some places
9010 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9011 the registers name strings.
9012 4. Fixed "signed / unsigned compare" compiler warnings.
9013 5. The PIC port manages its own allocation of the general purpose
9014 registers, but makes no attempt to reuse them. As a result when
9015 compiling it soon runs out of general purpose registers. Some
9016 additional code was added to the files pcode.c and device.c to walk
9017 through the function call tree and rename the registers so that they
9027 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9028 genPlus() & genMinus() when the result is the same as left or right

9034 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9036 Made bitfield a distinct type from bit so that bitfields
9037 convert as per ANSI C and bits retain their traditional
9038 boolean style behaviour. Implemented bitfield support in
9046 * src/ds390/gen.c: bit v bitfield split
9047 * src/z80/gen.c: New support for bitfields
9048 * support/regression/tests/bitfields.c: reenabled z80,
9051 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9053 Rules 246.x, 247.x relate to bitfields, the others speed up
9054 access to xdata mapped I/O devices.
9056 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9058 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9060 Cleaned up genPackBits and genUnpackBits and added two helper
9061 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9062 for literal assignments in genPackBits (thanks to Frieder for
9068 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9070 Fixed bug #748310 (pointer to function type mishandled when the
9071 function name is omitted). Also fixed a SIGSEGV when a function
9072 attribute (reentrant, etc) is used on a non-function or on a
9073 function but misplaced before the parameter list.
9075 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9077 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

9100 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9102 Made the constant following the "interrupt" keyword optional. If
9103 omitted, the function will not automatically be given an entry
9104 in the interrupt vector table (similar to #pragma NOIV, but
9105 less syntacticly kludgy). The interrupt number is also now
9106 range checked. Also fixed a bug in the high order bit example

9122 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9124 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9125 be re-activated by defining REDUCE_LITERALS)
9126 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9127 unsigned, but are signed by default
9128 * src/SDCCval.c (constVal): rearranged
9129 * src/SDCCval.c (valMod): preliminary fix
9130 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9582 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
9583 the regression tests I'm not brave enough to enable 245.b, 245.c
9584 * doc/sdccman.lyx: added latex preamble for hyperref package.
9585 Using pdflatex this will give you a hyperlinked pdf file with
9586 bookmarks. (prepend '%' before /usepackage if this breaks something)

9602 Applied patch from bug 737905 (renamed yylineo to mylineno):
9609 * src/pic16/pcode.c: Cleaned warnings
9610 * src/pic16/pcodeflow.c: Cleaned warnings
9611 * src/pic16/pcoderegs.c: Cleaned warnings

9624 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
9626 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
9627 it can be defined with CFLAGS when running configure
9628 * src/SDCCmain.c: fixed compiling + linking with object files
9630 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

9633 added --disable-pic16-port
9634 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9635 * src/SDCCmain.c: linkOptions is changed to set *,
9636 added if/endif conditional macros to remove options help
9637 messages from optionsTable when a port is not configured, added
9638 support for the PIc16 port in the ports table, when executing
9639 the compiler with no port specified on command line, a default
9640 port is selected with the new macro DEFAULT_PORT which is
9641 defined in port.h, in setDefaultOptions() linkOptions is removed
9642 from initialization assignment, since now it is a set,
9643 parseCmdLine uses setParseWithComma for linkOptions, in
9644 linkEdit() linkOptions are accessed with new function indexSet()
9645 which returns the i'th item of a set variable. See SDCCset.c, in
9646 linkEdit() when calling buildCmdLine(), added linkOptions as
9647 last argument. Now users can pass arguments to gplink via the
9648 -Wl option, main() uses pic16glue() to glue up pic16 programs
9649 * src/SDCCpeeph.c: various changes to support pic16

9660 * src/pic16/glue.c: commented out some error producing lines
9661 * src/pic16/main.c: __config directives are commented out to stop
9662 gpasm complaining and test the linkage with gplink, _linkCmd and
9663 _asmCmd changed to be more gplink and gpasm friendly
9664 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9665 produced an error when parsed, peep rule 12 is added to utilize
9666 movff, but it is commented out since the pCode does not support
9667 yet a command with 2 address arguments
9669 2003-05-18 <johan AT balder>
9671 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
9672 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9696 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
9698 2003-05-11 Borut Razem <borut.razem AT siol.net>
9700 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9701 the path of bin directory, so that PATH is the only env. variable, which has to be set
9702 in case of standard installation.
9703 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

10735 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10736 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10737 following files to include the previous two files: aslink.dsp,
10738 Makefile.aslink, Makefile.bcc, and Makefile.in.
10740 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10741 .adb instead of .cdb
10743 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10745 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10746 value from option --iram-size.
10748 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10750 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10753 2002-09-18 <wiml AT hhhh.org>
10755 * SDCClrange.h: exposed setFromRange() and setToRange()
10756 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10757 packRegsForAccUse() (bug 542397)
10758 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10759 multiple times and emitting the fetch operations more than once
10760 added aopGetUsesAcc() function to allow binary operators to
10761 fetch their operands in the correct order; made genMinus() emit
10762 compact code for X = LITERAL - Y
10764 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10765 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10766 sprintf() in line 1267.
10768 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

10772 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10773 Changes to aslink (All the changes are marked with 'JCF'):
10775 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10778 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10779 area BSEG. Also moves, if possible, the DATA area down into the internal
10780 ram so more space is available.
10782 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10785 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10786 not bytes. Function summary() which creates a memory usage summary
10787 file with extension .mem. Reports of overlaping stack and small stack
10788 size. If the space for the stack is less than 16 bytes aslink trows a
10791 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10792 the 8051. Option 'y' for memory summary output file.
10794 Changes to sdcc (All the changes are marked with 'JCF'):
10796 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10798 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10799 overlaying area for it (uses RegBankUsed[4]).
10801 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10802 bank zero as used by default. By default aslink locates the stack
10803 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10804 the creation of the .mem file. Delegates the allocation of data area
10805 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10806 the begining of the stack area to aslink.
10808 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10809 glue() in SDCCglue.c creates an area for it.

10812 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10813 sdcc/src/pic/glue.c:
10814 introduced atexit() handler for teporay files removal in case of
10815 errors, assertions, ...
10817 2002-08-29 Borut Razem <borut.razem AT siol.net>
10818 * sdcc/support/cpp2/auto-host_vc_in.h:
10819 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10820 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10821 Maybe there is a similar problem with BORLANDC? It should be checked!
10823 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10824 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10825 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10826 was not executed, and the compiler (cl) launched a warning:
10827 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10829 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10830 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10832 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10833 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10835 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10836 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10837 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10838 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10839 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10840 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10841 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10842 - added Release configuration in VS projects
10843 - review of compiler an linker options
10844 - VC .exe files are generated in bin_vc directory, not to interfere
10845 with binaries generated from other projects (cygwin, mingw, bcc ...)
10847 * sdcc/src/yacc.dsp: added
10849 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10850 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10851 and insert the version number definitions from .version
10853 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10855 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10856 added - genarate auto-host.h using auto-host_vc_in.h as template
10859 removed from CVS, generated automatically
10861 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10862 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10864 2002-08-11 Borut Razem <borut.razem AT siol.net>
10865 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10867 2002-08-10 Borut Razem <borut.razem AT siol.net>
10868 * src/SDCCmain.c (main):
10869 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10870 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10871 The consequence was that some temporary files were not removed.
10874 unification of code in functions tempfilename() and tempfile():
10875 function tempnam() is defined in Visual Studio 6.0 and .NET
10877 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10879 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10880 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10881 - removed compiler command line option /WX: Treats all warnings as errors
10882 - update a list of source files, included into the project
10884 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10885 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10886 changed project type to Generic Project so that can be correcly converted to VS.NET project
10888 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10890 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10892 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10894 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10895 added return 0 statements after assert() to make compiler happy
10897 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10898 added newline in the def file to keep MSC compiler satisfied
10900 * sdcc/src/z80/gen.c:
10901 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10902 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10903 - solved MSC error in function aopDump()
10905 * sdcc_vc.h: define PREFIX as "\\sdcc"
10907 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10908 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10911 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10912 - Rewrote the register banking algorithm.
10913 - Added pCode live-range analysis to registers (for now, only non-used and
10914 singly-used registers optimized away)
10916 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis

10945 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10947 2002-03-28 Johan Knol <johan AT balder>
10949 * src/SDCCval.c: fixed bug #532436

11080 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11082 * sdcc/src/SDCCloop.c:
11083 Previous fix was not good. basic blocks that have "break" or "return" are
11084 not really partof a loop , but live ranges used in these blocks should
11085 be live thru the entire loop, so set partOfLoop but don't add them to
11088 2002-02-21 <johan AT FRIJA>
11090 * src/SDCCcse.c: fixed bug #514308
11092 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
