951 genRightShift): fixed bug with non-constant bit shift stored to
952 a volatile result (SF Open Discussion forum thread #1616749).

2856 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2858 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2859 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2861 One basic decision: e.g. src/clean.mk includes further files. In order
2862 to make this work there are two solutions:
2863 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2864 run configure on them. This way they can use
2865 'include $(srcdir)/port-clean.mk'
2866 - always include clean.mk by the Makefile at the same level. To avoid
2867 that `make clean` tries to include and build Makefile.dep the
2868 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2869 implemented, because now even `make uninstall` doesn't create
2870 Makefile.in. clean.mk could be eliminated by pasting it in
2873 * debugger/mcs51/Makefile.in: build own objects from library sources
2874 (SLIB, SDCC) in current directory
2876 * configure, configure.in: renamed --disable-device-lib-build in
2877 --disable-device-lib; added --enable-doc, the required tools are
2878 searched by configure; added result message; the toolchain for the
2879 belonging ports are now only built, if the port is enabled.
2881 * support/regression/*: all output is written in directory gen, because
2882 the fwk and ports directories don't livet in the build tree using vpath
2884 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2885 --disable-device-lib, added --enable-doc, added section VPATH
2887 * sim/ucsim/configure.in,
2888 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2889 z80 are enabled by default
2891 2006-04-24 Raphael Neider <rneider AT web.de>
2893 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2894 to config word, "pic14_"-prefixed some extern functions
2895 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2896 config word has been found
2897 * src/pic/device.h: added prototypes
2898 * src/pic/pcode.c: added "pic14_"-prefix where needed
2899 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
2901 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
2903 (pic14emitRegularMap): ignore config words,
2904 (pic14createInterruptVect): moved generating __config directives away
2905 (picglue): have __config directives emitted
2907 2006-04-24 Borut Razem <borut.razem AT siol.net>

2915 fixes #1469504 and #1474602,
2916 (pCodeRegOptimizeRegUsage): fixed typo in comment

3162 implemented patch 1120823 Thanks to Willy De la Court (normal
3163 interrupts need an interrupt number now if they are made critical),
3164 and enabled nesting of critical functions though not for gbz80
3165 (genCritical, genEndCritical): added functions
3166 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
3167 * src/z80/mappings.i: added "ei" to all mappings

3179 the left operand is shorter than the result (c* = lit-c* + int),
3181 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
3184 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3186 * src/.version: increased version number to 2.5.5
3187 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
3188 linking is done manually in pic16 port's _linkEdit,
3189 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
3190 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
3191 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
3192 allocate asmop as AOP_ACC,
3193 (aopForRemat): added parameter 'bool result' in function declaration,
3194 (pic16_aopGet): return AOP_ACC when accessing WREG,
3195 (pic16_popGetTempReg): minor modification,
3196 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
3197 'pic16_allocWithIdx',

3204 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
3206 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
3207 call to allocReg, not by manually allocating a new one,
3208 (pic16_assignRegisters): now before going through the register
3209 allocating functions mark all registers as free. This eliminates some
3210 side effects resulting from peephole parser done earlier in the backbone
3212 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
3214 * src/SDCCicode.c (geniCodeLogic),

3234 (aopForSym, aopOp): increment asmop.allocated if reused,
3235 (freeAsmop): decrement asmop.allocated and check for zero instead of
3237 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
3238 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
3239 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

3262 2006-03-06 Borut Razem <borut.razem AT siol.net>
3264 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
3265 made the linker quiet

3270 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
3271 which dumps before the function entry point a data byte which represents
3272 the number of the local variables used by the specified function, added
3273 'xinst' for initial support for Extended Instruction Support,
3274 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
3275 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
3276 port->fun_prefix anymore (may change later),
3277 (genFunction, genEndFunction): do not store/restore local registers for
3278 _main (this should take care the --main-return command line option in
3280 (genOr): removed some legacy pic-port instructions,
3281 * src/pic16/genarith.c (genAddLit): re-enabled old code because
3282 performing operations with SFR's causes data to be written more than
3283 once to each SFR. Perhaps SFRs should be handled in special cases...
3284 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
3286 * src/pic16/main.c (_process_pragma): stack bound checking did not take
3287 into account for stack starting position,

3289 --extended or -y for Extended Instruction Support,
3290 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
3291 (deassignLRs): *** perhaps the most important change, old 'for' code
3292 (commented out for reference), didn't account for some registers which
3293 were left marked 'not free' after a pointer operation. The change
3294 reduces register usage a lot in some cases

5542 * device/lib/pic16/libc/utils/: minor modifications in the .S sources,
5543 * device/lib/pic16/startup/{crt0i.c, crt0iz.c}: redesign of the
5544 _do_cinit function, because the previous failed when local variables
5545 where not placed in the same memory bank,
5546 * device/lib/pic16/libsdcc/char/: various modifications to improve
5547 library performance,
5548 * doc/sdccman.lyx: some reorganization of the PIC16 part, added many
5549 information on the new functions of the c library and more...
5551 2005-03-28 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5553 * src/SDCCBBlock.c (iCodeBreakDown): fixed bug #1170212

5558 if condition == CARRY)
5559 * (genCmp): adapted to new genSkipc semantics
5560 * src/pic16/genutils.c (pic6_genCmp_special): removed side effect
5561 on rIfx (genCmp was broken)
5563 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5565 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
5566 * src/z80/main.c (_keywords[]),
5567 * src/SDCCglobal.h (struct options),
5569 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
5570 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
5571 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
5572 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
5573 always available in leading double underscore form. The C99 support is
5574 mostly missing, but it's a start.
5575 * support/regression/tests/bug-227710.c: fixed nonconforming use of
5576 reserved identifier "__data".
5578 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

5624 2005-03-20 Borut Razem <borut.razem AT siol.net>
5626 * support/scripts/inc2h.pl: WIN32 port

5632 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
5634 * device/include/stdint.h: added
5635 * device/lib/abs.c: added
5636 * device/lib/labs.c: added

5654 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
5656 * device/lib/printf_large.c: removed inline assembly for portability and
5657 readability. Use printf_fast if speed or size are more important.
5658 * src/pic16/gen.c: removed conditions around use of DEBUGpc
5659 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
5661 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
5663 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
5664 prevent compiler warning
5666 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
5668 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
5669 moved to level 0 and declared as static. Also they are explicit
5670 placed in access bank. This was necessery because some times they
5671 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
5672 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
5673 optimizations. Currently only compare to unsigned char is implemented,
5674 * src/pic16/gen.c: added fReturnIdx array,
5675 * (struct resolvedIfx) is moved to gen.h and made public,
5676 * (struct _G): added sregsAlloc and sregsAllocSet fields,
5677 * (aopForSym): added an optimization to directly store in stack of
5678 the operand of a SEND iCode,
5679 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
5680 but as registers instead (AOP_REG) using the fReturnIdx array,
5681 * (pic16_freeAsmop): remove the freed register from the
5682 _G.sregsAlloc field,
5683 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
5684 a compare of 'WREG',
5685 * (pic16_popGetTempRegCond): changed function prototype, now
5686 function takes also a bitVector argument v which holds the current
5687 set of registers that are allocated for stack access by aopForSym,
5688 registers allocated in aopForSym for accessing stack symbols are not
5689 any more part of the functions usedRegs field,
5690 * (genCall): some times aopOp is called for a stack variable to be
5691 send, aopForSym might perform the push, if this is true make sure
5692 that genCall doesn't push the variable twice by testing _G.resDirect,
5693 * (genFunction): changed testing for unspecified interrupt number
5694 from 256 to INTNO_UNSPEC,
5695 * modified selection scheme of frame pointer generation. Previously
5696 if function did use local registers a frame pointer was generated,
5697 now a frame pointer is generated only if function has arguments
5698 (that need PLUSW2 register access), or has stack arguments, or the
5699 compiler is not instructed to omit the frame pointer,
5700 * (genEndFunction): before restoring local registers that were saved
5701 in the function preamble, also restore the registers that *might*
5702 have been allocated for stack access,
5703 * (genRet): removed some old comments,
5704 * (genCmp, the active (RN's) version): added a call to the
5705 pic16_genCmp_special function to perform the compare with a more
5706 robust and optimized way,
5707 * (genInline): a feature has been added in inline code generation,
5708 which allows a wildcard variable substitution when writing inline
5709 assembly. Code is incomplete and experimental therefore undocumented,
5710 * (genCast): changed order of aopOp for result and right to allow
5711 aopForSym to directly load the result if possible,
5712 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
5713 perform an optimized compare on some selected special occasions,
5714 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
5715 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
5716 generate an IVT any more,
5717 * src/pic16/main.c (pic16_optionsTable): added command line option
5719 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
5720 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
5722 * src/pic16/NOTES: Raphael Neider added in list of active developers
5723 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
5724 jumptable_end to prevent bug #,
5725 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
5726 inCond and outCond fields,
5727 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
5728 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
5729 turn off register spilling,
5730 * (packRegsForOneUse): synced with other ports' versions although it
5731 is not used currently,
5732 * (pic16_packRegisters): added an optimization while reading
5733 structure bitfields, some registers may be saved (malloc code is
5734 decreased by 80 bytes)
5736 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
5738 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
5739 left is a bitfield, if yes, then don't optimize assignment. Perhaps
5740 this can be optimized more?
5742 2005-03-10 Raphael Neider <rneider AT web.de>
5744 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
5745 genNearPointerGet): (hopefully) fixed access to bitfields via
5746 pointers (p->bitN = x; and x = p->bitN; failed)
5748 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

5935 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
5936 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
5937 this might fix SIGSEGVs on MinGW...
5938 * src/SDCCopt.c (killDeadCode): restored original behaviour
5939 (volatile operands might get thrown away though)
5941 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

5981 macro STACK_MODEL_{SMALL/LARGE} when compiling and assembling to
5982 reflect stack model used,
5983 * src/pic16/ralloc.c (pic16_allocDirReg): when operand is allocated

6421 be extensively tested in the future. Standard disclaimer here.
6422 Library is not automatically build yet. But one can build it by
6423 invoking 'make' inside the libc directory.

6438 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
6440 * (genCast): began a fix to optimize the casting of a bit to another
6441 bit, now assigning a bitfield to another bitfield will fail, sorry,

9464 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
9466 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
9467 loaded with the linker search paths (-L arguments) and the libraries
9468 to be linked with the current source (-l arguments). Changes
9469 currently will affect only the pic16 port.
9470 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
9471 include path the port specific paths and port specific libraries,
9472 * gplink command now contains the $3 argument,
9473 * src/pic16/device.h,
9474 * src/pic16/device.c,: structure PIC_device is made public and
9475 renamed to PIC16_device, the same for variable Pics which is renamed

9490 Documenting changes from previous commits.
9491 * configure.in (version 1.56),
9492 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
9493 when generating output files to configure the pic16 library,
9494 but now I've commented it out, since gputils aren't installed in the
9495 SF compile farm, so library won't compile
9497 * device/lib/Makefile.in (version 1.56): initially I've added in
9498 target 'all' the prerequestive 'model-pic16' so it compiled the
9499 pic16 library, but now I've commented it out for the same reasons
9501 * added targets 'model-pic16' and 'objects-pic16' to compile the
9503 * added target 'port-specific-objects-pic16' to handle the
9504 generated libraries and copy them into the build/ directory
9505 * added target 'clean-intermediate-pic16' to clean intermediate
9506 files into pic16 directory
9507 * in target 'installdirs' added line to create directory pic16 in
9508 the installation path
9510 * device/include/Makefile.in (version 1.11): in target 'install'
9511 added lines to copy all header files to installation path,
9512 * in target 'installdirs' added line create directory for pic16
9513 headers in the installation path

9528 * src/z80/main.c (_parseOptions): fixed the portmode= command line
9529 option so that it actually works. Made it specific to the z80, since
9530 the gbz80 doesn't have these kinds of I/O ports.
9532 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9534 * device/include/z180.h,

9558 via literal number. The symbol is placed in the corresponding
9559 position of the data ram
9560 * (pic16_dump_section): relocatable and absolute uninitialized
9561 data are now emitted in sorted order to reduce section naming,
9562 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
9563 weren't marked as being in the access bank,
9565 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
9567 Added portion of GNU PIC Library under the directory
9568 device/include/pic16 and device/lib/pic16. These files
9569 contain the declarations of SFRs for the PIC18Fxx2 devices.
9570 The directory is initialized via configure from toplevel.
9572 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
9574 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
9575 the spilllocations to be compared correctly
9577 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
9579 * src/SDCCast.c (decorateType): fixed bug introduced today

9599 * doc/sdccman.lyx: Moved and added some sections, small changes
9600 all over. Telling LaTeX to be less strict with word spacing
9601 to better keep the right margin. Changed some notes about
9602 maintainance of the ports in section 3.2.1 - is it OK like this?
9604 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

9642 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
9644 * src/pic16/peeph.def: all peepholes with movff are commented out,
9645 because there is a problem in the pcode peep optimizer,
9646 * src/pic16/ralloc.c: the register allocator can now reuse local

9648 * src/pic16/ralloc.h: added flag isLocal in structure regs,
9650 Added file src/pic16/NOTES with information about program writing on
9651 the current port version.

9680 gen51Code): more efficient parameter receive for --model-large
9683 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9686 * src/z80/main.c: added missed needLinkerScript flags (more than
9687 one port structure defined in these file)
9688 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

9704 needLinkerScript flag
9706 * src/pic16/gen.c (genAddrOf): fixed bug #863624
9707 * src/pic/glue.c: added variable udata_section_name to
9708 override default uninitialized data segment definition for
9709 devices only with SHAREBANK memory (reported from Erik Epetrich)
9710 * (pic14emitOverlay): modified to emit a commented overlay segment
9711 directive when no overlay data exist
9712 * (picglue): modified to emit uninitialized data segment
9713 according to udata_section_name

9723 2004-01-07 Borut Razem <borut.razem AT siol.net>
9725 * support/scripts/sdcc.nsi: update PATH
9726 * support/scripts/sdcc.ico: craeted

9733 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9735 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
9737 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

9739 include information about variables allocated to the overlay
9742 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9744 * as/mcs51/lkmain.c: Help about -Y option

9756 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9758 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
9759 (default behaviour).
9761 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9763 A python script to validate compiler diagnostic messages. It can be
9764 used to verify that sdcc complains about bad c source code and
9765 gives a good location of the error.
9766 * support/valdiag/Makefile,
9767 * support/valdiag/valdiag.py,
9768 * support/valdiag/tests/*
9770 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9772 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

9783 * src/common.h: added ifndef/define/endif macros
9784 around the header file.
9785 Bug reported from Jesus Calvino-Fraga
9787 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
9789 * sdcc.spec: updated
9790 * device/include/Makefile.in: don't install CVS directories
9791 * device/lib/Makefile.in: added removal of CVS directories after install
9792 * doc/Makefile: fixed install, added local_icons
9793 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
9794 * src/mcs51/gen.c (genRightShift): fixed bug #870788
9795 * src/ds390/gen.c (genRightShift): fixed bug #870788
9796 * src/SDCCast.c (decorateType): fixed bug #870781
9798 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9800 PIC16 port related changes:
9801 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
9802 added variable stackPos,
9804 * gen.c: genCall, assignResultValue: added support for
9805 pushing/retrieving function parameters to/from stack,
9806 genFunction,genEndFunction: setup stack frame for the
9808 genAddrOf: will be changed according to bug 863624
9810 * added files genutils.c and genutils.h which contain gen*
9811 debugged and optimised functions extracted from gen.c
9813 * glue.c: added variable 'externs' which holds extern symbols,
9814 pic16emitRegularMap: is modified to properly handle relocatable
9815 symbols under the new scheme,
9816 pic16createInterruptVect: is modified
9817 pic16printPublics: is modified to emit 'global' assembler directives,
9818 added pic16_printExterns to print extern symbols,
9819 pic16glue: initializes stack/frame pointer in the beginning of
9820 the assembly output. Temporary hack, will be corrected later,
9821 because gplink yet does not support stack and SDCC does not
9822 yet support a type of crt0.o object to create the final binary.
9824 * Removed many lines that contain 8051 legacy code.
9825 * The code is finally placed under a 'code' directive.
9826 * Added port specific options.
9828 * _process_pragma: simplified since now we do not need *special*
9829 include file to define SFR registers. But a separate header
9830 will be needed. This will be developed later.
9831 * _pic16_parseOptions: added, parses port specific options:
9832 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9833 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9834 --preplace-udata-with=
9836 * _pic16_setDefaultOptions: modified to initialize section names,
9837 but hack is temporarly out of order since it needs improvement.
9838 * _pic16_genAssemblerPreamble: configuration words are emitted by
9839 their address instead of their name. This part is incomplete and
9840 supports only the 18Fxx2 devices. Other devices will emit an error
9841 during assembly since they do not contain the same set of config
9843 * _pic16_genIVT: is modified,
9845 * pcode.c: added definitions for some hardware registers that are needed
9847 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9848 All PCI entries are updated. Now LFSR is supported.
9849 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9850 * added pic16_newpCodeOpLit2 to support instructions with
9851 two literal arguments
9852 * pic16_pCode2str: corrected code that emits assembler instructions
9853 with two literal operands and those that have an access bit modifier
9854 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9855 this fixes a bug which caused some labels to be lost, when an
9856 assembler directive was added, i.e. banksel,
9857 * pic16_FixRegisterBanking: improved logic that causes the insertion
9859 * InlineFunction: functions that are called once, are not any more
9860 inlined. This can be a port option in the future,
9862 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9864 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9865 hold the corresponding uninitialized symbols,
9866 * pic16_allocProcessorRegister: registers have explicit marked the
9868 * pic16_allocInternalRegister: registers are explicit marked as
9870 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9871 processing list, so bit registers were lost,
9874 * ralloc.h: added field 'accessBank' and original symbol operand
9875 in register definition,
9876 * removed the field isMapped from register definition,
9878 ** Several functions have been removed from various sources:
9879 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9880 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9881 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9882 pic16_assignRelocatableRegisters
9884 ** others have been introduced:
9885 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9886 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9888 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9890 * support/scripts/inc2h.pl: changed definition of BIT_AT
9891 to emit 'sbit at' instead of 'bit at'. This was a request.
9893 PIC16 port related preliminary changes:
9894 * gen.c: prefixed function popRegFromString with
9895 pic16_ and all references to it corrected
9896 * pcode.c: all pic16_pc_* hardware registers prefixed
9897 with underscore (_),
9898 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9899 * ralloc.c: newReg(): when register is REG_SFR then
9900 set address to rIdx,
9901 pic16_allocProcessorRegister(): marks register wasUsed=0
9902 pic16_writeUsedRegs(): added a call to assign processor
9903 registers via pic16_assignFixedRegisters
9905 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9907 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9908 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9909 variables in unused register banks. Also the SSEG is placed
9910 wherever there is enough space for it, and IDATA can be anywhere
9911 in internal RAM. For now compile using -Wl-Y[stack_size].
9912 The mem file is different for this option as well, since it
9913 makes no sense of talking about DSEG lenght.
9915 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9917 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9918 in certain cases, e.g. when ROM assignment, patch provided
9919 from Albert den Haan.
9921 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

10164 it breaks with bitfields, extern declarations, and gcse analysis.
10165 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
10166 could be assigned through a pointer, so don't complain.

10474 not occur if the control variable is involved with a
10475 relational operator.

10953 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10955 Z80 and MCS51 linkers complaint if a public symbol is defined
10956 in more than one library module:
10960 * as/mcs51/Makefile.in
10962 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10964 A few small changes that speed up the peephole optimizer.
10968 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10970 Try to make the peephole optimizer smarter by maintaining
10971 an association between the assembly source code and the
10972 iCodes that originated them. Put this information to use
10973 with a new peephole rule condition "notVolatile" so that
10974 the rules can be aggressive yet still safe.
10979 * src/mcs51/peeph.def
10981 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10985 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10986 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10987 if the left or right operand symbols have the accuse flag set.
10989 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10991 Changed the type of the result of the ! (NOT) operator to char;
10992 previously it returned the same type as the source. This allows
10993 us to eliminate all the genFloatNot functions (all of its target
10994 implementations were very buggy) since !float can use the same
10997 * src/SDCCicode.c (ast2iCode): ! returns char
10998 * src/mcs51/gen.c (genNot, genNotFloat),
10999 * src/ds390/gen.c (genNot, genNotFloat),
11000 * src/z80/gen.c (genNot, genNotFloat),
11001 * src/pic/gen.c (genNot, genNotFloat),
11002 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

11006 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11007 1. Interrupt would not compile properly. Ensure PCLATH register is saved
11008 during interrupts. Ensure WSAVE is located at a shared bank address.
11009 2. Fixed page selection in some places
11010 3. Fixed BTFSS/C to where necessary use registers directly and not simply
11011 the registers name strings.
11012 4. Fixed "signed / unsigned compare" compiler warnings.
11013 5. The PIC port manages its own allocation of the general purpose
11014 registers, but makes no attempt to reuse them. As a result when
11015 compiling it soon runs out of general purpose registers. Some
11016 additional code was added to the files pcode.c and device.c to walk
11017 through the function call tree and rename the registers so that they
11027 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
11028 genPlus() & genMinus() when the result is the same as left or right
11030 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

11034 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11036 Made bitfield a distinct type from bit so that bitfields
11037 convert as per ANSI C and bits retain their traditional
11038 boolean style behaviour. Implemented bitfield support in
11046 * src/ds390/gen.c: bit v bitfield split
11047 * src/z80/gen.c: New support for bitfields
11048 * support/regression/tests/bitfields.c: reenabled z80,
11051 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11053 Rules 246.x, 247.x relate to bitfields, the others speed up
11054 access to xdata mapped I/O devices.
11056 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
11058 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11060 Cleaned up genPackBits and genUnpackBits and added two helper
11061 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
11062 for literal assignments in genPackBits (thanks to Frieder for
11068 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11070 Fixed bug #748310 (pointer to function type mishandled when the
11071 function name is omitted). Also fixed a SIGSEGV when a function
11072 attribute (reentrant, etc) is used on a non-function or on a
11073 function but misplaced before the parameter list.
11075 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
11077 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
11078 * support/Util/SDCCerr.h,
11079 * support/Util/SDCCerr.c: Added func attr misuse error msg
11081 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
11083 Fixed bug #787649 by anonymous
11084 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
11085 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
11087 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11089 Fixed numerous bitfield problems.

11098 * support/regression/tests/bitfields.c: tests added
11100 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11102 Made the constant following the "interrupt" keyword optional. If
11103 omitted, the function will not automatically be given an entry
11104 in the interrupt vector table (similar to #pragma NOIV, but
11105 less syntacticly kludgy). The interrupt number is also now
11106 range checked. Also fixed a bug in the high order bit example
11113 * support/Util/SDCCerr.c
11114 * support/Util/SDCCerr.h

11122 * src/SDCCsymt.c (computeType): literals are handled the same way as any
11124 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
11125 be re-activated by defining REDUCE_LITERALS)
11126 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
11127 unsigned, but are signed by default
11128 * src/SDCCval.c (constVal): rearranged
11129 * src/SDCCval.c (valMod): preliminary fix
11130 * src/SDCCval.c (valCastLiteral): use TYPE_* types

11170 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
11171 * src/SDCCval.c (constVal): changed default to signed; hex and octal
11172 constants are unsigned; added recognition of "u" flag for unsigned
11173 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
11174 * src/SDCCval.c (valDiv, valMod): fixed signdness

11636 added if/endif conditional macros to remove options help
11637 messages from optionsTable when a port is not configured, added
11638 support for the PIc16 port in the ports table, when executing
11639 the compiler with no port specified on command line, a default
11640 port is selected with the new macro DEFAULT_PORT which is
11641 defined in port.h, in setDefaultOptions() linkOptions is removed
11642 from initialization assignment, since now it is a set,
11643 parseCmdLine uses setParseWithComma for linkOptions, in
11644 linkEdit() linkOptions are accessed with new function indexSet()
11645 which returns the i'th item of a set variable. See SDCCset.c, in
11646 linkEdit() when calling buildCmdLine(), added linkOptions as
11647 last argument. Now users can pass arguments to gplink via the
11648 -Wl option, main() uses pic16glue() to glue up pic16 programs

11660 * src/pic16/glue.c: commented out some error producing lines
11661 * src/pic16/main.c: __config directives are commented out to stop
11662 gpasm complaining and test the linkage with gplink, _linkCmd and
11663 _asmCmd changed to be more gplink and gpasm friendly
11664 * src/pic16/peeph.def: peep rule 3 is commented out, since it
11665 produced an error when parsed, peep rule 12 is added to utilize
11666 movff, but it is commented out since the pCode does not support
11667 yet a command with 2 address arguments
11669 2003-05-18 <johan AT balder>
11671 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

12786 not bytes. Function summary() which creates a memory usage summary
12787 file with extension .mem. Reports of overlaping stack and small stack
12788 size. If the space for the stack is less than 16 bytes aslink trows a
12791 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
12792 the 8051. Option 'y' for memory summary output file.
12794 Changes to sdcc (All the changes are marked with 'JCF'):
12796 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
12798 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
12799 overlaying area for it (uses RegBankUsed[4]).
12801 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
12802 bank zero as used by default. By default aslink locates the stack
12803 (equivalent to --stack-after-data). Pass option 'y' to aslink for
12804 the creation of the .mem file. Delegates the allocation of data area
12805 to aslink (it is not longer 0x30 by default). If --stack-loc passes
12806 the begining of the stack area to aslink.
12808 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
12809 glue() in SDCCglue.c creates an area for it.
12811 2002-09-03 Borut Razem <borut.razem AT siol.net>
12812 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12813 sdcc/src/pic/glue.c:
12814 introduced atexit() handler for teporay files removal in case of
12815 errors, assertions, ...
12817 2002-08-29 Borut Razem <borut.razem AT siol.net>
12818 * sdcc/support/cpp2/auto-host_vc_in.h:
12819 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12820 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12821 Maybe there is a similar problem with BORLANDC? It should be checked!
12823 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12824 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12825 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12826 was not executed, and the compiler (cl) launched a warning:
12827 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12829 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12830 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
12832 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
12833 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
12835 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12836 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
12837 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
12838 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12839 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
12840 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
12841 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
12842 - added Release configuration in VS projects
12843 - review of compiler an linker options
12844 - VC .exe files are generated in bin_vc directory, not to interfere
12845 with binaries generated from other projects (cygwin, mingw, bcc ...)
12847 * sdcc/src/yacc.dsp: added
12849 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12850 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12851 and insert the version number definitions from .version
12853 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12855 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
12856 added - genarate auto-host.h using auto-host_vc_in.h as template
12859 removed from CVS, generated automatically
12861 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
12862 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12864 2002-08-11 Borut Razem <borut.razem AT siol.net>
12865 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12867 2002-08-10 Borut Razem <borut.razem AT siol.net>
12868 * src/SDCCmain.c (main):
12869 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12870 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12871 The consequence was that some temporary files were not removed.
12874 unification of code in functions tempfilename() and tempfile():
12875 function tempnam() is defined in Visual Studio 6.0 and .NET
12877 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12879 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12880 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
12881 - removed compiler command line option /WX: Treats all warnings as errors
12882 - update a list of source files, included into the project
12884 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12885 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12886 changed project type to Generic Project so that can be correcly converted to VS.NET project
12888 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12890 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
12892 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
12894 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12895 added return 0 statements after assert() to make compiler happy
12897 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12898 added newline in the def file to keep MSC compiler satisfied
12900 * sdcc/src/z80/gen.c:
12901 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
12902 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
12903 - solved MSC error in function aopDump()
12905 * sdcc_vc.h: define PREFIX as "\\sdcc"
12907 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
12908 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

12945 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
12947 2002-03-28 Johan Knol <johan AT balder>
12949 * src/SDCCval.c: fixed bug #532436
12951 2002-03-14 Scott Dattalo <scott AT dattalo.com>

12956 Added -p option. Allows port dependent processor to be specified.
12959 Initialized the new field char *Processor field to NULL in all ports
12962 Compiler generated registers for interrupt context saving
12963 were not getting allocated.
12965 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
12968 Fixed left shift. Will promote the left side of a left shift
12969 if a) left shifting more than size of operand or b) when assigned
12970 to something size > size of left side

13080 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
13082 * sdcc/src/SDCCloop.c:
13083 Previous fix was not good. basic blocks that have "break" or "return" are
13084 not really partof a loop , but live ranges used in these blocks should
13085 be live thru the entire loop, so set partOfLoop but don't add them to
13088 2002-02-21 <johan AT FRIJA>
13090 * src/SDCCcse.c: fixed bug #514308
13092 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

13096 statement inside a loop, it was not being considered part of the loop.
13098 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
13100 2002-02-10 Karl Bongers <karl AT turbobit.com>
