2911 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2913 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2914 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2916 One basic decision: e.g. src/clean.mk includes further files. In order
2917 to make this work there are two solutions:
2918 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2919 run configure on them. This way they can use
2920 'include $(srcdir)/port-clean.mk'
2921 - always include clean.mk by the Makefile at the same level. To avoid
2922 that `make clean` tries to include and build Makefile.dep the
2923 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2924 implemented, because now even `make uninstall` doesn't create
2925 Makefile.in. clean.mk could be eliminated by pasting it in
2928 * debugger/mcs51/Makefile.in: build own objects from library sources
2929 (SLIB, SDCC) in current directory
2931 * configure, configure.in: renamed --disable-device-lib-build in
2932 --disable-device-lib; added --enable-doc, the required tools are
2933 searched by configure; added result message; the toolchain for the
2934 belonging ports are now only built, if the port is enabled.
2936 * support/regression/*: all output is written in directory gen, because
2937 the fwk and ports directories don't livet in the build tree using vpath
2939 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2940 --disable-device-lib, added --enable-doc, added section VPATH
2942 * sim/ucsim/configure.in,
2943 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2944 z80 are enabled by default
2946 2006-04-24 Raphael Neider <rneider AT web.de>
2948 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2949 to config word, "pic14_"-prefixed some extern functions
2950 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2951 config word has been found
2952 * src/pic/device.h: added prototypes
2953 * src/pic/pcode.c: added "pic14_"-prefix where needed
2954 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
2956 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

2959 (pic14createInterruptVect): moved generating __config directives away

2969 registers that have not been assigned proper liveranges,
2970 fixes #1469504 and #1474602,
2971 (pCodeRegOptimizeRegUsage): fixed typo in comment
2973 2006-04-24 Borut Razem <borut.razem AT siol.net>
2975 * device/examples/main8051.c: deleted - it was removed from CVS
2976 24.mar.2000 and after that modified 18.feb.2001, so it reappered
2977 after the transition to Subversion
2978 * src/SDCCalloc.h: deleted - it was removed from CVS
2979 3.feb.2001 and after that modified 18.feb.2001, so it reappered

3217 implemented patch 1120823 Thanks to Willy De la Court (normal
3218 interrupts need an interrupt number now if they are made critical),
3219 and enabled nesting of critical functions though not for gbz80
3220 (genCritical, genEndCritical): added functions
3221 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
3222 * src/z80/mappings.i: added "ei" to all mappings

3234 the left operand is shorter than the result (c* = lit-c* + int),
3236 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
3239 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3241 * src/.version: increased version number to 2.5.5
3242 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
3243 linking is done manually in pic16 port's _linkEdit,
3244 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
3245 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
3246 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
3247 allocate asmop as AOP_ACC,
3248 (aopForRemat): added parameter 'bool result' in function declaration,
3249 (pic16_aopGet): return AOP_ACC when accessing WREG,
3250 (pic16_popGetTempReg): minor modification,

3261 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
3262 call to allocReg, not by manually allocating a new one,
3263 (pic16_assignRegisters): now before going through the register
3264 allocating functions mark all registers as free. This eliminates some
3265 side effects resulting from peephole parser done earlier in the backbone
3267 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

3325 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
3326 which dumps before the function entry point a data byte which represents
3327 the number of the local variables used by the specified function, added
3328 'xinst' for initial support for Extended Instruction Support,
3329 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
3330 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
3331 port->fun_prefix anymore (may change later),
3332 (genFunction, genEndFunction): do not store/restore local registers for
3333 _main (this should take care the --main-return command line option in
3335 (genOr): removed some legacy pic-port instructions,
3336 * src/pic16/genarith.c (genAddLit): re-enabled old code because
3337 performing operations with SFR's causes data to be written more than
3338 once to each SFR. Perhaps SFRs should be handled in special cases...
3339 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
3341 * src/pic16/main.c (_process_pragma): stack bound checking did not take
3342 into account for stack starting position,

3344 --extended or -y for Extended Instruction Support,
3345 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
3346 (deassignLRs): *** perhaps the most important change, old 'for' code
3347 (commented out for reference), didn't account for some registers which
3348 were left marked 'not free' after a pointer operation. The change
3349 reduces register usage a lot in some cases
3351 2006-03-04 Borut Razem <borut.razem AT siol.net>

5618 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5620 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
5621 * src/z80/main.c (_keywords[]),
5622 * src/SDCCglobal.h (struct options),
5624 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
5625 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
5626 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
5627 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
5628 always available in leading double underscore form. The C99 support is
5629 mostly missing, but it's a start.
5630 * support/regression/tests/bug-227710.c: fixed nonconforming use of
5631 reserved identifier "__data".
5633 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

5677 immedDom() returning wrong block; probably fixes bug #1160833)
5679 2005-03-20 Borut Razem <borut.razem AT siol.net>
5681 * support/scripts/inc2h.pl: WIN32 port

5685 * device/lib/makefile.in: added abs.c and labs.c
5687 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
5689 * device/include/stdint.h: added
5690 * device/lib/abs.c: added

5709 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
5711 * device/lib/printf_large.c: removed inline assembly for portability and
5712 readability. Use printf_fast if speed or size are more important.
5713 * src/pic16/gen.c: removed conditions around use of DEBUGpc
5714 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
5716 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
5718 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
5719 prevent compiler warning
5721 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
5723 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
5724 moved to level 0 and declared as static. Also they are explicit
5725 placed in access bank. This was necessery because some times they
5726 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
5727 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
5728 optimizations. Currently only compare to unsigned char is implemented,
5729 * src/pic16/gen.c: added fReturnIdx array,
5730 * (struct resolvedIfx) is moved to gen.h and made public,
5731 * (struct _G): added sregsAlloc and sregsAllocSet fields,
5732 * (aopForSym): added an optimization to directly store in stack of
5733 the operand of a SEND iCode,
5734 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
5735 but as registers instead (AOP_REG) using the fReturnIdx array,
5736 * (pic16_freeAsmop): remove the freed register from the
5737 _G.sregsAlloc field,
5738 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
5739 a compare of 'WREG',
5740 * (pic16_popGetTempRegCond): changed function prototype, now
5741 function takes also a bitVector argument v which holds the current
5742 set of registers that are allocated for stack access by aopForSym,
5743 registers allocated in aopForSym for accessing stack symbols are not
5744 any more part of the functions usedRegs field,
5745 * (genCall): some times aopOp is called for a stack variable to be
5746 send, aopForSym might perform the push, if this is true make sure
5747 that genCall doesn't push the variable twice by testing _G.resDirect,
5748 * (genFunction): changed testing for unspecified interrupt number
5749 from 256 to INTNO_UNSPEC,
5750 * modified selection scheme of frame pointer generation. Previously
5751 if function did use local registers a frame pointer was generated,
5752 now a frame pointer is generated only if function has arguments
5753 (that need PLUSW2 register access), or has stack arguments, or the
5754 compiler is not instructed to omit the frame pointer,
5755 * (genEndFunction): before restoring local registers that were saved
5756 in the function preamble, also restore the registers that *might*
5757 have been allocated for stack access,
5758 * (genRet): removed some old comments,
5759 * (genCmp, the active (RN's) version): added a call to the
5760 pic16_genCmp_special function to perform the compare with a more
5761 robust and optimized way,
5762 * (genInline): a feature has been added in inline code generation,
5763 which allows a wildcard variable substitution when writing inline
5764 assembly. Code is incomplete and experimental therefore undocumented,
5765 * (genCast): changed order of aopOp for result and right to allow
5766 aopForSym to directly load the result if possible,
5767 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
5768 perform an optimized compare on some selected special occasions,
5769 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
5770 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
5771 generate an IVT any more,
5772 * src/pic16/main.c (pic16_optionsTable): added command line option
5774 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
5775 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
5777 * src/pic16/NOTES: Raphael Neider added in list of active developers
5778 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
5779 jumptable_end to prevent bug #,
5780 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
5781 inCond and outCond fields,
5782 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
5783 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
5784 turn off register spilling,
5785 * (packRegsForOneUse): synced with other ports' versions although it
5786 is not used currently,
5787 * (pic16_packRegisters): added an optimization while reading
5788 structure bitfields, some registers may be saved (malloc code is
5789 decreased by 80 bytes)
5791 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
5793 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
5794 left is a bitfield, if yes, then don't optimize assignment. Perhaps
5795 this can be optimized more?
5797 2005-03-10 Raphael Neider <rneider AT web.de>
5799 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
5800 genNearPointerGet): (hopefully) fixed access to bitfields via
5801 pointers (p->bitN = x; and x = p->bitN; failed)
5803 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
5805 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

5846 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
5847 to keep the correct label reference count when adding/removing references
5848 to labels. A peephole file using this is appended to patch #1144962.

5980 * src/pic16/main.c (_process_pragma): fixed another malloc bug
5981 (sizeof(sectNames) changed to sizeof(sectName))
5982 Both patches fix segfaults under MinGW.
5984 2005-01-23 Raphael Neider <rneider AT web.de>

5987 Safe_[mc]?alloc()'ed variables
5988 * src/pic16/gen.c (pic16_aopOp,pic16_popGet): added handling
5989 of (byte sized) temporaries (assign them to WREG for now)
5990 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
5991 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
5992 this might fix SIGSEGVs on MinGW...
5993 * src/SDCCopt.c (killDeadCode): restored original behaviour
5994 (volatile operands might get thrown away though)

6422 comparisons, and supports quoted literals
6423 * src/mcs51/peeph.def: restored rule 177.d with an extra condition
6425 2004-12-02 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

6433 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6435 Adding support for replacing ljmps with sjmps in jumptables
6436 generated for switch statements. For now you need to set the
6437 environment variable SDCC_SJMP_JUMPTABLE to enable this.
6438 Now 4 algorithms for mcs51 jumptable generation are used:
6439 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
6440 addresses loaded pc-relative for up to 112 cases and stack-pushing
6441 target addresses loaded with offset from dptr for up to 256 cases.
6443 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
6444 * src/mcs51/main.c: adapted constants for switch table generation
6445 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

6465 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
6467 Large cummulative patch for pic16 port.
6468 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
6469 to call when a stack overflow occurs,
6470 * (malloc.h): added CVS Id tag,
6471 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
6473 * added libc directory. The current version of LibC contains string
6474 functions, ctype functions and macros and some functions of the
6475 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
6476 be extensively tested in the future. Standard disclaimer here.
6477 Library is not automatically build yet. But one can build it by
6478 invoking 'make' inside the libc directory.
6479 * added ADC library under libio. Preliminary version yet.
6481 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
6482 * src/pic16/gen.c (aopForRemat): asmop size is filled by
6483 aopForRemat() now and not by pic16_aopOp(),
6484 * (pic16_popGetTempReg): removed warning messgae when allocating
6485 temporary registers, its a buggy feature and will be removed,
6486 * (pic16_popGet): set register instance field in AOP_CRY,
6487 * (pic16_outBitC): fixed for results in size greater than 1,
6488 * (genUminusFloat): fixed for pic16, ported code from mcs51,
6489 * (pic16_storeForReturn): optimized return of 0,
6490 * (genCmp): experimental code for new genCmp which uses PIC18's
6491 special compare&skip instructions. Initial tests fail some times
6492 with variables grater than 1 byte in size, so new code is disabled,
6493 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
6495 * (genCast): began a fix to optimize the casting of a bit to another
6496 bit, now assigning a bitfield to another bitfield will fail, sorry,
6497 * src/pic16/main.c: disabled the use of lr-support feature,
6498 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
6499 * added some function prototypes, added function _debugf prototype,
6500 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
6501 bits with offset (case PO_GPR_BIT),
6502 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
6504 * (isBankInstruction): modified to return 0 for no banking instruction,
6505 and 1 for banking instruction,
6506 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
6507 caused stop processing pCodes after a inline assembly block,
6508 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
6509 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
6510 registers when it shouldn't,
6511 * src/pic16/ralloc.c (allocReg): add preliminary support for
6512 supporting a limited set of temporary registers,
6514 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6516 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
6517 genDataPointerSet): ensure assignments always copy in MSB to LSB
6519 (loadRegFromAop): recognize CLRH optimization,
6520 (genFunction): optimize RECEIVE iCodes in reentrant functions
6522 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6524 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
6525 --out-fmt-s19 turning into --out-fmt-elf if s19 was already

6534 * device/lib/_gptrgetc.c (_gptrgetc),
6535 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
6536 instead of sjmp to ret
6537 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
6538 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
6540 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

9522 loaded with the linker search paths (-L arguments) and the libraries
9523 to be linked with the current source (-l arguments). Changes
9524 currently will affect only the pic16 port.
9525 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
9526 include path the port specific paths and port specific libraries,
9527 * gplink command now contains the $3 argument,
9528 * src/pic16/device.h,
9529 * src/pic16/device.c,: structure PIC_device is made public and
9530 renamed to PIC16_device, the same for variable Pics which is renamed
9531 to Pics16. Updated all references to them.
9532 * src/pic16/glue.c (pic16glue): corrected bug with code
9533 initialization which bypassed the variable initializations block.
9535 * device/lib/pic16/Makefile.rules: removed --penable-stack from
9536 COMPILE_FLAGS and added the --nostdinc option
9538 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9540 * device/include/mc68hc908jb8.h: Register defs for another member
9541 of the hc08 family. Contributed by Bjorn Bringert - thanks!
9543 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
9545 Documenting changes from previous commits.
9546 * configure.in (version 1.56),
9547 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
9548 when generating output files to configure the pic16 library,
9549 but now I've commented it out, since gputils aren't installed in the
9550 SF compile farm, so library won't compile
9552 * device/lib/Makefile.in (version 1.56): initially I've added in
9553 target 'all' the prerequestive 'model-pic16' so it compiled the
9554 pic16 library, but now I've commented it out for the same reasons
9556 * added targets 'model-pic16' and 'objects-pic16' to compile the
9558 * added target 'port-specific-objects-pic16' to handle the
9559 generated libraries and copy them into the build/ directory
9560 * added target 'clean-intermediate-pic16' to clean intermediate
9561 files into pic16 directory
9562 * in target 'installdirs' added line to create directory pic16 in
9563 the installation path
9565 * device/include/Makefile.in (version 1.11): in target 'install'
9566 added lines to copy all header files to installation path,
9567 * in target 'installdirs' added line create directory for pic16
9568 headers in the installation path
9570 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

9583 * src/z80/main.c (_parseOptions): fixed the portmode= command line
9584 option so that it actually works. Made it specific to the z80, since
9585 the gbz80 doesn't have these kinds of I/O ports.
9587 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9589 * device/include/z180.h,

9602 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9604 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
9605 changed interrupt vector table generation to only emit declared vectors.

9611 Mainly changes to support compilation of the device libraries
9612 * src/pic16/device.c: stack is allocated via symbol and not
9613 via literal number. The symbol is placed in the corresponding
9614 position of the data ram
9615 * (pic16_dump_section): relocatable and absolute uninitialized
9616 data are now emitted in sorted order to reduce section naming,
9617 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
9618 weren't marked as being in the access bank,
9620 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
9622 Added portion of GNU PIC Library under the directory
9623 device/include/pic16 and device/lib/pic16. These files
9624 contain the declarations of SFRs for the PIC18Fxx2 devices.
9625 The directory is initialized via configure from toplevel.
9627 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
9629 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
9630 the spilllocations to be compared correctly
9632 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
9634 * src/SDCCast.c (decorateType): fixed bug introduced today
9636 2004-01-12 Borut Razem <borut.razem AT siol.net>

9652 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9654 * doc/sdccman.lyx: Moved and added some sections, small changes
9655 all over. Telling LaTeX to be less strict with word spacing
9656 to better keep the right margin. Changed some notes about
9657 maintainance of the ports in section 3.2.1 - is it OK like this?
9659 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

9696 UPPER for immediate operands,
9697 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
9699 * src/pic16/peeph.def: all peepholes with movff are commented out,
9700 because there is a problem in the pcode peep optimizer,
9701 * src/pic16/ralloc.c: the register allocator can now reuse local

9703 * src/pic16/ralloc.h: added flag isLocal in structure regs,
9705 Added file src/pic16/NOTES with information about program writing on
9706 the current port version.

9735 gen51Code): more efficient parameter receive for --model-large
9738 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9741 * src/z80/main.c: added missed needLinkerScript flags (more than
9742 one port structure defined in these file)
9743 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

9759 needLinkerScript flag
9761 * src/pic16/gen.c (genAddrOf): fixed bug #863624
9762 * src/pic/glue.c: added variable udata_section_name to
9763 override default uninitialized data segment definition for
9764 devices only with SHAREBANK memory (reported from Erik Epetrich)
9765 * (pic14emitOverlay): modified to emit a commented overlay segment
9766 directive when no overlay data exist
9767 * (picglue): modified to emit uninitialized data segment
9768 according to udata_section_name

9778 2004-01-07 Borut Razem <borut.razem AT siol.net>
9780 * support/scripts/sdcc.nsi: update PATH
9781 * support/scripts/sdcc.ico: craeted
9783 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>

9794 include information about variables allocated to the overlay
9797 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9799 * as/mcs51/lkmain.c: Help about -Y option

9811 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9813 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
9814 (default behaviour).
9816 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9818 A python script to validate compiler diagnostic messages. It can be
9819 used to verify that sdcc complains about bad c source code and
9820 gives a good location of the error.
9821 * support/valdiag/Makefile,
9822 * support/valdiag/valdiag.py,
9823 * support/valdiag/tests/*
9825 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9838 * src/common.h: added ifndef/define/endif macros
9839 around the header file.
9840 Bug reported from Jesus Calvino-Fraga
9842 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
9844 * sdcc.spec: updated
9845 * device/include/Makefile.in: don't install CVS directories
9846 * device/lib/Makefile.in: added removal of CVS directories after install
9847 * doc/Makefile: fixed install, added local_icons
9848 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
9849 * src/mcs51/gen.c (genRightShift): fixed bug #870788
9850 * src/ds390/gen.c (genRightShift): fixed bug #870788
9851 * src/SDCCast.c (decorateType): fixed bug #870781
9853 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9855 PIC16 port related changes:
9856 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
9857 added variable stackPos,
9859 * gen.c: genCall, assignResultValue: added support for
9860 pushing/retrieving function parameters to/from stack,
9861 genFunction,genEndFunction: setup stack frame for the
9863 genAddrOf: will be changed according to bug 863624
9865 * added files genutils.c and genutils.h which contain gen*
9866 debugged and optimised functions extracted from gen.c
9868 * glue.c: added variable 'externs' which holds extern symbols,
9869 pic16emitRegularMap: is modified to properly handle relocatable
9870 symbols under the new scheme,
9871 pic16createInterruptVect: is modified
9872 pic16printPublics: is modified to emit 'global' assembler directives,
9873 added pic16_printExterns to print extern symbols,
9874 pic16glue: initializes stack/frame pointer in the beginning of
9875 the assembly output. Temporary hack, will be corrected later,
9876 because gplink yet does not support stack and SDCC does not
9877 yet support a type of crt0.o object to create the final binary.
9879 * Removed many lines that contain 8051 legacy code.
9880 * The code is finally placed under a 'code' directive.
9881 * Added port specific options.
9883 * _process_pragma: simplified since now we do not need *special*
9884 include file to define SFR registers. But a separate header
9885 will be needed. This will be developed later.
9886 * _pic16_parseOptions: added, parses port specific options:
9887 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9888 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9889 --preplace-udata-with=
9891 * _pic16_setDefaultOptions: modified to initialize section names,
9892 but hack is temporarly out of order since it needs improvement.
9893 * _pic16_genAssemblerPreamble: configuration words are emitted by
9894 their address instead of their name. This part is incomplete and
9895 supports only the 18Fxx2 devices. Other devices will emit an error
9896 during assembly since they do not contain the same set of config
9898 * _pic16_genIVT: is modified,
9900 * pcode.c: added definitions for some hardware registers that are needed
9902 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9903 All PCI entries are updated. Now LFSR is supported.
9904 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9905 * added pic16_newpCodeOpLit2 to support instructions with
9906 two literal arguments
9907 * pic16_pCode2str: corrected code that emits assembler instructions
9908 with two literal operands and those that have an access bit modifier
9909 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9910 this fixes a bug which caused some labels to be lost, when an
9911 assembler directive was added, i.e. banksel,
9912 * pic16_FixRegisterBanking: improved logic that causes the insertion
9914 * InlineFunction: functions that are called once, are not any more
9915 inlined. This can be a port option in the future,
9917 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9919 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9920 hold the corresponding uninitialized symbols,
9921 * pic16_allocProcessorRegister: registers have explicit marked the
9923 * pic16_allocInternalRegister: registers are explicit marked as
9925 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9926 processing list, so bit registers were lost,
9929 * ralloc.h: added field 'accessBank' and original symbol operand
9930 in register definition,
9931 * removed the field isMapped from register definition,
9933 ** Several functions have been removed from various sources:
9934 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9935 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9936 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9937 pic16_assignRelocatableRegisters
9939 ** others have been introduced:
9940 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9941 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9943 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9945 * support/scripts/inc2h.pl: changed definition of BIT_AT
9946 to emit 'sbit at' instead of 'bit at'. This was a request.
9948 PIC16 port related preliminary changes:
9949 * gen.c: prefixed function popRegFromString with
9950 pic16_ and all references to it corrected
9951 * pcode.c: all pic16_pc_* hardware registers prefixed
9952 with underscore (_),
9953 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9954 * ralloc.c: newReg(): when register is REG_SFR then
9955 set address to rIdx,
9956 pic16_allocProcessorRegister(): marks register wasUsed=0
9957 pic16_writeUsedRegs(): added a call to assign processor
9958 registers via pic16_assignFixedRegisters
9960 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9962 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9963 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9964 variables in unused register banks. Also the SSEG is placed
9965 wherever there is enough space for it, and IDATA can be anywhere
9966 in internal RAM. For now compile using -Wl-Y[stack_size].
9967 The mem file is different for this option as well, since it
9968 makes no sense of talking about DSEG lenght.
9970 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9972 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9973 in certain cases, e.g. when ROM assignment, patch provided
9974 from Albert den Haan.
9976 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

10963 and JUMPTABLE iCodes properly now (worked by accident before)
10964 * src/mcs51/gen.c (leftRightUseAcc),
10965 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
10966 iCode properly now. Use getSize instead of nRegs since a & b
10967 aren't part of the nRegs tally.
10969 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
10971 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()
10972 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
10973 before instructions that use the _STATUS register
10975 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
10977 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
10978 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
10979 fetching of the pointer
10980 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
10981 copied from genNearPointerSet()
10982 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
10983 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
10984 If they pop r0/r1 they must be called in the opposite order than aopOp().
10985 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
10986 (resp. --stack-auto), prepared for --xstack
10988 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10990 * doc/sdccman.lyx: reverted tables to those in cvs 1.64
10992 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10994 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
10995 these ports have their own __sdcc_external_start()
10997 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
10999 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11000 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
11001 type for bits was changed. It resulted in bit variables becoming
11002 global, which is not permitted in PIC 14 assembly output.
11004 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11006 * doc/sdccman.lyx: various additions and updates. Rearranged sections
11008 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11010 Z80 and MCS51 linkers complaint if a public symbol is defined
11011 in more than one library module:
11015 * as/mcs51/Makefile.in
11017 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11019 A few small changes that speed up the peephole optimizer.
11023 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11025 Try to make the peephole optimizer smarter by maintaining
11026 an association between the assembly source code and the
11027 iCodes that originated them. Put this information to use
11028 with a new peephole rule condition "notVolatile" so that
11029 the rules can be aggressive yet still safe.
11034 * src/mcs51/peeph.def
11036 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11040 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
11041 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
11042 if the left or right operand symbols have the accuse flag set.
11044 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11046 Changed the type of the result of the ! (NOT) operator to char;
11047 previously it returned the same type as the source. This allows
11048 us to eliminate all the genFloatNot functions (all of its target
11049 implementations were very buggy) since !float can use the same
11052 * src/SDCCicode.c (ast2iCode): ! returns char
11053 * src/mcs51/gen.c (genNot, genNotFloat),
11054 * src/ds390/gen.c (genNot, genNotFloat),
11055 * src/z80/gen.c (genNot, genNotFloat),
11056 * src/pic/gen.c (genNot, genNotFloat),
11057 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
11059 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
11061 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11062 1. Interrupt would not compile properly. Ensure PCLATH register is saved
11063 during interrupts. Ensure WSAVE is located at a shared bank address.
11064 2. Fixed page selection in some places
11065 3. Fixed BTFSS/C to where necessary use registers directly and not simply
11066 the registers name strings.
11067 4. Fixed "signed / unsigned compare" compiler warnings.
11068 5. The PIC port manages its own allocation of the general purpose
11069 registers, but makes no attempt to reuse them. As a result when
11070 compiling it soon runs out of general purpose registers. Some
11071 additional code was added to the files pcode.c and device.c to walk
11072 through the function call tree and rename the registers so that they
11082 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
11083 genPlus() & genMinus() when the result is the same as left or right
11085 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

11089 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11091 Made bitfield a distinct type from bit so that bitfields
11092 convert as per ANSI C and bits retain their traditional
11093 boolean style behaviour. Implemented bitfield support in
11101 * src/ds390/gen.c: bit v bitfield split
11102 * src/z80/gen.c: New support for bitfields
11103 * support/regression/tests/bitfields.c: reenabled z80,
11106 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11108 Rules 246.x, 247.x relate to bitfields, the others speed up
11109 access to xdata mapped I/O devices.
11111 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
11113 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11115 Cleaned up genPackBits and genUnpackBits and added two helper
11116 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
11117 for literal assignments in genPackBits (thanks to Frieder for
11123 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11125 Fixed bug #748310 (pointer to function type mishandled when the
11126 function name is omitted). Also fixed a SIGSEGV when a function
11127 attribute (reentrant, etc) is used on a non-function or on a
11128 function but misplaced before the parameter list.
11130 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
11132 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
11133 * support/Util/SDCCerr.h,
11134 * support/Util/SDCCerr.c: Added func attr misuse error msg
11136 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
11138 Fixed bug #787649 by anonymous
11139 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
11140 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
11142 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11144 Fixed numerous bitfield problems.
11146 * src/SDCC.y: More bitfield related error checking

11153 * support/regression/tests/bitfields.c: tests added
11155 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11157 Made the constant following the "interrupt" keyword optional. If
11158 omitted, the function will not automatically be given an entry
11159 in the interrupt vector table (similar to #pragma NOIV, but
11160 less syntacticly kludgy). The interrupt number is also now
11161 range checked. Also fixed a bug in the high order bit example
11168 * support/Util/SDCCerr.c
11169 * support/Util/SDCCerr.h
11172 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

11175 * src/SDCCicode.c (operandOperation): rewritten some ops
11176 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
11177 * src/SDCCsymt.c (computeType): literals are handled the same way as any
11179 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
11180 be re-activated by defining REDUCE_LITERALS)
11181 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
11182 unsigned, but are signed by default
11183 * src/SDCCval.c (constVal): rearranged
11184 * src/SDCCval.c (valMod): preliminary fix
11185 * src/SDCCval.c (valCastLiteral): use TYPE_* types

11225 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
11226 * src/SDCCval.c (constVal): changed default to signed; hex and octal
11227 constants are unsigned; added recognition of "u" flag for unsigned
11228 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
11229 * src/SDCCval.c (valDiv, valMod): fixed signdness
11230 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
11231 signedness of modulo, left and right shift

11637 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
11638 the regression tests I'm not brave enough to enable 245.b, 245.c
11639 * doc/sdccman.lyx: added latex preamble for hyperref package.
11640 Using pdflatex this will give you a hyperlinked pdf file with

11691 added if/endif conditional macros to remove options help
11692 messages from optionsTable when a port is not configured, added
11693 support for the PIc16 port in the ports table, when executing
11694 the compiler with no port specified on command line, a default
11695 port is selected with the new macro DEFAULT_PORT which is
11696 defined in port.h, in setDefaultOptions() linkOptions is removed
11697 from initialization assignment, since now it is a set,
11698 parseCmdLine uses setParseWithComma for linkOptions, in
11699 linkEdit() linkOptions are accessed with new function indexSet()
11700 which returns the i'th item of a set variable. See SDCCset.c, in
11701 linkEdit() when calling buildCmdLine(), added linkOptions as
11702 last argument. Now users can pass arguments to gplink via the
11703 -Wl option, main() uses pic16glue() to glue up pic16 programs

11716 * src/pic16/main.c: __config directives are commented out to stop
11717 gpasm complaining and test the linkage with gplink, _linkCmd and
11718 _asmCmd changed to be more gplink and gpasm friendly
11719 * src/pic16/peeph.def: peep rule 3 is commented out, since it
11720 produced an error when parsed, peep rule 12 is added to utilize
11721 movff, but it is commented out since the pCode does not support
11722 yet a command with 2 address arguments
11724 2003-05-18 <johan AT balder>
11726 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

12790 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
12791 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
12792 following files to include the previous two files: aslink.dsp,
12793 Makefile.aslink, Makefile.bcc, and Makefile.in.
12795 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
12796 .adb instead of .cdb
12798 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12800 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
12801 value from option --iram-size.
12803 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12805 * /sdcc/as/mcs51/lklist.c: added boundary check before using
12808 2002-09-18 <wiml AT hhhh.org>
12810 * SDCClrange.h: exposed setFromRange() and setToRange()
12811 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
12812 packRegsForAccUse() (bug 542397)
12813 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
12814 multiple times and emitting the fetch operations more than once
12815 added aopGetUsesAcc() function to allow binary operators to
12816 fetch their operands in the correct order; made genMinus() emit
12817 compact code for X = LITERAL - Y
12819 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12820 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
12821 sprintf() in line 1267.
12823 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12824 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
12827 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12828 Changes to aslink (All the changes are marked with 'JCF'):
12830 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
12833 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
12834 area BSEG. Also moves, if possible, the DATA area down into the internal
12835 ram so more space is available.
12837 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
12840 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
12841 not bytes. Function summary() which creates a memory usage summary
12842 file with extension .mem. Reports of overlaping stack and small stack
12843 size. If the space for the stack is less than 16 bytes aslink trows a
12846 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
12847 the 8051. Option 'y' for memory summary output file.
12849 Changes to sdcc (All the changes are marked with 'JCF'):
12851 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
12853 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
12854 overlaying area for it (uses RegBankUsed[4]).
12856 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
12857 bank zero as used by default. By default aslink locates the stack
12858 (equivalent to --stack-after-data). Pass option 'y' to aslink for
12859 the creation of the .mem file. Delegates the allocation of data area
12860 to aslink (it is not longer 0x30 by default). If --stack-loc passes
12861 the begining of the stack area to aslink.
12863 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
12864 glue() in SDCCglue.c creates an area for it.
12866 2002-09-03 Borut Razem <borut.razem AT siol.net>
12867 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12868 sdcc/src/pic/glue.c:
12869 introduced atexit() handler for teporay files removal in case of
12870 errors, assertions, ...
12872 2002-08-29 Borut Razem <borut.razem AT siol.net>
12873 * sdcc/support/cpp2/auto-host_vc_in.h:
12874 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12875 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12876 Maybe there is a similar problem with BORLANDC? It should be checked!
12878 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12879 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12880 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12881 was not executed, and the compiler (cl) launched a warning:
12882 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12884 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12885 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
12887 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
12888 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
12890 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12891 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
12892 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
12893 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12894 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
12895 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
12896 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
12897 - added Release configuration in VS projects
12898 - review of compiler an linker options
12899 - VC .exe files are generated in bin_vc directory, not to interfere
12900 with binaries generated from other projects (cygwin, mingw, bcc ...)
12902 * sdcc/src/yacc.dsp: added
12904 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12905 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12906 and insert the version number definitions from .version
12908 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12910 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
12911 added - genarate auto-host.h using auto-host_vc_in.h as template
12914 removed from CVS, generated automatically
12916 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
12917 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12919 2002-08-11 Borut Razem <borut.razem AT siol.net>
12920 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12922 2002-08-10 Borut Razem <borut.razem AT siol.net>
12923 * src/SDCCmain.c (main):
12924 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12925 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12926 The consequence was that some temporary files were not removed.
12929 unification of code in functions tempfilename() and tempfile():
12930 function tempnam() is defined in Visual Studio 6.0 and .NET
12932 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12934 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12935 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
12936 - removed compiler command line option /WX: Treats all warnings as errors
12937 - update a list of source files, included into the project
12939 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12940 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12941 changed project type to Generic Project so that can be correcly converted to VS.NET project
12943 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12945 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
12947 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
12949 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12950 added return 0 statements after assert() to make compiler happy
12952 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12953 added newline in the def file to keep MSC compiler satisfied
12955 * sdcc/src/z80/gen.c:
12956 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
12957 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
12958 - solved MSC error in function aopDump()
12960 * sdcc_vc.h: define PREFIX as "\\sdcc"
12962 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
12963 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

12966 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
12967 - Rewrote the register banking algorithm.
12968 - Added pCode live-range analysis to registers (for now, only non-used and
12969 singly-used registers optimized away)
12971 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
12973 * support/scripts/inc2h.pl Kevin L. Pauba <klpauba AT cox.net> submitted this perl script for converting MicroChip include files into SDCC Pic include files.

12996 * src/z80/main.c: Added force callee saves for jaune.
12998 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
13000 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
13002 2002-03-28 Johan Knol <johan AT balder>
13004 * src/SDCCval.c: fixed bug #532436
13006 2002-03-14 Scott Dattalo <scott AT dattalo.com>
13008 Added "char *Processor" field to the port structure.
13011 Added -p option. Allows port dependent processor to be specified.
13014 Initialized the new field char *Processor field to NULL in all ports
13017 Compiler generated registers for interrupt context saving
13018 were not getting allocated.
13020 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
13023 Fixed left shift. Will promote the left side of a left shift
13024 if a) left shifting more than size of operand or b) when assigned
13025 to something size > size of left side
13027 2002-03-14 Scott Dattalo <scott AT dattalo.com>
13029 tons of changes. Register allocation has been

13031 analysis is restructured. ...
13033 * src/pic/device.h:
13036 * src/pic/device.c:
13037 Added. device.c is a PIC port hack to accomodate variations

13135 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
13137 * sdcc/src/SDCCloop.c:
13138 Previous fix was not good. basic blocks that have "break" or "return" are
13139 not really partof a loop , but live ranges used in these blocks should
13140 be live thru the entire loop, so set partOfLoop but don't add them to
13143 2002-02-21 <johan AT FRIJA>
13145 * src/SDCCcse.c: fixed bug #514308
13147 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
13150 Fixed BUG #519583. If a conditional block ended in a return/break
