272 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
274 Enabled VPATH feature: changed nearly all Makefiles (149 files).
275 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
277 One basic decision: e.g. src/clean.mk includes further files. In order
278 to make this work there are two solutions:
279 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
280 run configure on them. This way they can use
281 'include $(srcdir)/port-clean.mk'
282 - always include clean.mk by the Makefile at the same level. To avoid
283 that `make clean` tries to include and build Makefile.dep the
284 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
285 implemented, because now even `make uninstall` doesn't create
286 Makefile.in. clean.mk could be eliminated by pasting it in
289 * debugger/mcs51/Makefile.in: build own objects from library sources
290 (SLIB, SDCC) in current directory
292 * configure, configure.in: renamed --disable-device-lib-build in
293 --disable-device-lib; added --enable-doc, the required tools are
294 searched by configure; added result message; the toolchain for the
295 belonging ports are now only built, if the port is enabled.
297 * support/regression/*: all output is written in directory gen, because
298 the fwk and ports directories don't livet in the build tree using vpath
300 * doc/sdccman.lyx: renamed --disable-device-lib-build to
301 --disable-device-lib, added --enable-doc, added section VPATH
303 * sim/ucsim/configure.in,
304 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
305 z80 are enabled by default
307 2006-04-24 Raphael Neider <rneider AT web.de>
309 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
310 to config word, "pic14_"-prefixed some extern functions
311 (pic14_emitConfigWord): emit __config directive(s) if assignment to
312 config word has been found
313 * src/pic/device.h: added prototypes
314 * src/pic/pcode.c: added "pic14_"-prefix where needed
315 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
317 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
319 (pic14emitRegularMap): ignore config words,
320 (pic14createInterruptVect): moved generating __config directives away

331 fixes #1469504 and #1474602,
332 (pCodeRegOptimizeRegUsage): fixed typo in comment

580 and enabled nesting of critical functions though not for gbz80
581 (genCritical, genEndCritical): added functions
582 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
583 * src/z80/mappings.i: added "ei" to all mappings

589 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
590 archive with gcc 4.1 on mips and wrote the patch"
592 2006-03-16 Raphael Neider <rneider AT web.de>
594 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
595 the left operand is shorter than the result (c* = lit-c* + int),
597 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
600 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
602 * src/.version: increased version number to 2.5.5
603 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
604 linking is done manually in pic16 port's _linkEdit,
605 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
606 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
607 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
608 allocate asmop as AOP_ACC,
609 (aopForRemat): added parameter 'bool result' in function declaration,
610 (pic16_aopGet): return AOP_ACC when accessing WREG,

622 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
623 call to allocReg, not by manually allocating a new one,
624 (pic16_assignRegisters): now before going through the register
625 allocating functions mark all registers as free. This eliminates some
626 side effects resulting from peephole parser done earlier in the backbone
628 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
630 * src/SDCCicode.c (geniCodeLogic),

678 2006-03-06 Borut Razem <borut.razem AT siol.net>
680 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
681 made the linker quiet
683 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>

686 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
687 which dumps before the function entry point a data byte which represents
688 the number of the local variables used by the specified function, added
689 'xinst' for initial support for Extended Instruction Support,
690 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
691 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
692 port->fun_prefix anymore (may change later),
693 (genFunction, genEndFunction): do not store/restore local registers for
694 _main (this should take care the --main-return command line option in
696 (genOr): removed some legacy pic-port instructions,
697 * src/pic16/genarith.c (genAddLit): re-enabled old code because
698 performing operations with SFR's causes data to be written more than
699 once to each SFR. Perhaps SFRs should be handled in special cases...
700 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
702 * src/pic16/main.c (_process_pragma): stack bound checking did not take
703 into account for stack starting position,
704 (struct OPTIONS pic16_optionsTable): added command line argument
705 --extended or -y for Extended Instruction Support,
706 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
707 (deassignLRs): *** perhaps the most important change, old 'for' code
708 (commented out for reference), didn't account for some registers which
709 were left marked 'not free' after a pointer operation. The change
710 reduces register usage a lot in some cases

3036 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
3037 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
3038 immedDom() returning wrong block; probably fixes bug #1160833)
3040 2005-03-20 Borut Razem <borut.razem AT siol.net>
3042 * support/scripts/inc2h.pl: WIN32 port
3044 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
3046 * device/lib/makefile.in: added abs.c and labs.c
3048 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
3050 * device/include/stdint.h: added
3051 * device/lib/abs.c: added
3052 * device/lib/labs.c: added
3053 * device/include/stdlib.h: added abs() and labs() prototypes
3054 * device/lib/libsdcc.lib: added abs and labs
3055 * device/include/float.h,
3056 * device/lib/_fsmul.c,
3057 * device/lib/printf_fast.c,
3058 * device/lib/printf_tiny.c: updated comments
3060 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3062 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
3065 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3067 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
3068 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
3070 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3072 * device/lib/printf_large.c: removed inline assembly for portability and
3073 readability. Use printf_fast if speed or size are more important.
3074 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3075 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3077 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3079 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3080 prevent compiler warning
3082 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3084 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3085 moved to level 0 and declared as static. Also they are explicit
3086 placed in access bank. This was necessery because some times they
3087 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3088 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3089 optimizations. Currently only compare to unsigned char is implemented,
3090 * src/pic16/gen.c: added fReturnIdx array,
3091 * (struct resolvedIfx) is moved to gen.h and made public,
3092 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3093 * (aopForSym): added an optimization to directly store in stack of
3094 the operand of a SEND iCode,
3095 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3096 but as registers instead (AOP_REG) using the fReturnIdx array,
3097 * (pic16_freeAsmop): remove the freed register from the
3098 _G.sregsAlloc field,
3099 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3100 a compare of 'WREG',
3101 * (pic16_popGetTempRegCond): changed function prototype, now
3102 function takes also a bitVector argument v which holds the current
3103 set of registers that are allocated for stack access by aopForSym,
3104 registers allocated in aopForSym for accessing stack symbols are not
3105 any more part of the functions usedRegs field,
3106 * (genCall): some times aopOp is called for a stack variable to be
3107 send, aopForSym might perform the push, if this is true make sure
3108 that genCall doesn't push the variable twice by testing _G.resDirect,
3109 * (genFunction): changed testing for unspecified interrupt number
3110 from 256 to INTNO_UNSPEC,
3111 * modified selection scheme of frame pointer generation. Previously
3112 if function did use local registers a frame pointer was generated,
3113 now a frame pointer is generated only if function has arguments
3114 (that need PLUSW2 register access), or has stack arguments, or the
3115 compiler is not instructed to omit the frame pointer,
3116 * (genEndFunction): before restoring local registers that were saved
3117 in the function preamble, also restore the registers that *might*
3118 have been allocated for stack access,
3119 * (genRet): removed some old comments,
3120 * (genCmp, the active (RN's) version): added a call to the
3121 pic16_genCmp_special function to perform the compare with a more
3122 robust and optimized way,
3123 * (genInline): a feature has been added in inline code generation,
3124 which allows a wildcard variable substitution when writing inline
3125 assembly. Code is incomplete and experimental therefore undocumented,
3126 * (genCast): changed order of aopOp for result and right to allow
3127 aopForSym to directly load the result if possible,
3128 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3129 perform an optimized compare on some selected special occasions,
3130 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3131 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3132 generate an IVT any more,
3133 * src/pic16/main.c (pic16_optionsTable): added command line option
3135 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3136 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3138 * src/pic16/NOTES: Raphael Neider added in list of active developers
3139 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3140 jumptable_end to prevent bug #,
3141 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3142 inCond and outCond fields,
3143 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3144 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3145 turn off register spilling,
3146 * (packRegsForOneUse): synced with other ports' versions although it
3147 is not used currently,
3148 * (pic16_packRegisters): added an optimization while reading
3149 structure bitfields, some registers may be saved (malloc code is
3150 decreased by 80 bytes)
3152 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3154 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3155 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3156 this can be optimized more?
3158 2005-03-10 Raphael Neider <rneider AT web.de>
3160 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3161 genNearPointerGet): (hopefully) fixed access to bitfields via
3162 pointers (p->bitN = x; and x = p->bitN; failed)
3164 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3352 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
3353 this might fix SIGSEGVs on MinGW...

3797 generated for switch statements. For now you need to set the
3798 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3799 Now 4 algorithms for mcs51 jumptable generation are used:
3800 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

3832 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3834 * added libc directory. The current version of LibC contains string
3835 functions, ctype functions and macros and some functions of the
3836 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3837 be extensively tested in the future. Standard disclaimer here.
3838 Library is not automatically build yet. But one can build it by

3850 * (pic16_storeForReturn): optimized return of 0,
3851 * (genCmp): experimental code for new genCmp which uses PIC18's
3852 special compare&skip instructions. Initial tests fail some times
3853 with variables grater than 1 byte in size, so new code is disabled,
3854 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3856 * (genCast): began a fix to optimize the casting of a bit to another
3857 bit, now assigning a bitfield to another bitfield will fail, sorry,

3866 and 1 for banking instruction,
3867 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3868 caused stop processing pCodes after a inline assembly block,

3871 registers when it shouldn't,
3872 * src/pic16/ralloc.c (allocReg): add preliminary support for
3873 supporting a limited set of temporary registers,
3875 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3881 (genFunction): optimize RECEIVE iCodes in reentrant functions
3883 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3885 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

3899 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
3901 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

6835 code / RAM are in the same page / bank. This means the linker can
6836 safely allocate code/RAM of separate ASM files to different pages/banks.
6837 * doc/sdccman.lyx: added Slade's tips
6838 * src/mcs51/peeph.def: fixed bug #880768

6880 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6882 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6883 loaded with the linker search paths (-L arguments) and the libraries
6884 to be linked with the current source (-l arguments). Changes
6885 currently will affect only the pic16 port.
6886 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6887 include path the port specific paths and port specific libraries,
6888 * gplink command now contains the $3 argument,
6889 * src/pic16/device.h,
6890 * src/pic16/device.c,: structure PIC_device is made public and
6891 renamed to PIC16_device, the same for variable Pics which is renamed

6906 Documenting changes from previous commits.
6907 * configure.in (version 1.56),
6908 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6909 when generating output files to configure the pic16 library,
6910 but now I've commented it out, since gputils aren't installed in the
6911 SF compile farm, so library won't compile
6913 * device/lib/Makefile.in (version 1.56): initially I've added in
6914 target 'all' the prerequestive 'model-pic16' so it compiled the
6915 pic16 library, but now I've commented it out for the same reasons
6917 * added targets 'model-pic16' and 'objects-pic16' to compile the
6919 * added target 'port-specific-objects-pic16' to handle the
6920 generated libraries and copy them into the build/ directory
6921 * added target 'clean-intermediate-pic16' to clean intermediate
6922 files into pic16 directory
6923 * in target 'installdirs' added line to create directory pic16 in
6924 the installation path
6926 * device/include/Makefile.in (version 1.11): in target 'install'
6927 added lines to copy all header files to installation path,
6928 * in target 'installdirs' added line create directory for pic16
6929 headers in the installation path

6944 * src/z80/main.c (_parseOptions): fixed the portmode= command line
6945 option so that it actually works. Made it specific to the z80, since
6946 the gbz80 doesn't have these kinds of I/O ports.
6948 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6950 * device/include/z180.h,

6972 Mainly changes to support compilation of the device libraries
6973 * src/pic16/device.c: stack is allocated via symbol and not
6974 via literal number. The symbol is placed in the corresponding
6975 position of the data ram
6976 * (pic16_dump_section): relocatable and absolute uninitialized
6977 data are now emitted in sorted order to reduce section naming,
6978 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6979 weren't marked as being in the access bank,
6981 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6983 Added portion of GNU PIC Library under the directory
6984 device/include/pic16 and device/lib/pic16. These files
6985 contain the declarations of SFRs for the PIC18Fxx2 devices.
6986 The directory is initialized via configure from toplevel.
6988 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
6990 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

6997 2004-01-12 Borut Razem <borut.razem AT siol.net>
6999 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,
7000 doc/sdccman.lyx: upper case pragmas are deprecated
7002 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
7004 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results

7015 * doc/sdccman.lyx: Moved and added some sections, small changes
7016 all over. Telling LaTeX to be less strict with word spacing
7017 to better keep the right margin. Changed some notes about
7018 maintainance of the ports in section 3.2.1 - is it OK like this?
7020 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
7022 SDCC source changes:
7023 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

7029 processor registers declared internally by the port are emitted in
7030 the translation as equates,
7031 * src/pic16/gen.c: inline code is passed unprocessed to the

7172 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7174 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7175 (default behaviour).
7177 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7179 A python script to validate compiler diagnostic messages. It can be
7180 used to verify that sdcc complains about bad c source code and
7181 gives a good location of the error.
7182 * support/valdiag/Makefile,
7183 * support/valdiag/valdiag.py,

7199 * src/common.h: added ifndef/define/endif macros
7200 around the header file.
7201 Bug reported from Jesus Calvino-Fraga
7203 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7205 * sdcc.spec: updated
7206 * device/include/Makefile.in: don't install CVS directories
7207 * device/lib/Makefile.in: added removal of CVS directories after install
7208 * doc/Makefile: fixed install, added local_icons
7209 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7210 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7211 * src/ds390/gen.c (genRightShift): fixed bug #870788
7212 * src/SDCCast.c (decorateType): fixed bug #870781
7214 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7216 PIC16 port related changes:
7217 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7218 added variable stackPos,
7220 * gen.c: genCall, assignResultValue: added support for
7221 pushing/retrieving function parameters to/from stack,
7222 genFunction,genEndFunction: setup stack frame for the
7224 genAddrOf: will be changed according to bug 863624
7226 * added files genutils.c and genutils.h which contain gen*
7227 debugged and optimised functions extracted from gen.c
7229 * glue.c: added variable 'externs' which holds extern symbols,
7230 pic16emitRegularMap: is modified to properly handle relocatable
7231 symbols under the new scheme,
7232 pic16createInterruptVect: is modified
7233 pic16printPublics: is modified to emit 'global' assembler directives,
7234 added pic16_printExterns to print extern symbols,
7235 pic16glue: initializes stack/frame pointer in the beginning of
7236 the assembly output. Temporary hack, will be corrected later,
7237 because gplink yet does not support stack and SDCC does not
7238 yet support a type of crt0.o object to create the final binary.
7240 * Removed many lines that contain 8051 legacy code.
7241 * The code is finally placed under a 'code' directive.
7242 * Added port specific options.
7244 * _process_pragma: simplified since now we do not need *special*
7245 include file to define SFR registers. But a separate header
7246 will be needed. This will be developed later.
7247 * _pic16_parseOptions: added, parses port specific options:
7248 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7249 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7250 --preplace-udata-with=
7252 * _pic16_setDefaultOptions: modified to initialize section names,
7253 but hack is temporarly out of order since it needs improvement.
7254 * _pic16_genAssemblerPreamble: configuration words are emitted by
7255 their address instead of their name. This part is incomplete and
7256 supports only the 18Fxx2 devices. Other devices will emit an error
7257 during assembly since they do not contain the same set of config
7259 * _pic16_genIVT: is modified,
7261 * pcode.c: added definitions for some hardware registers that are needed
7263 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7264 All PCI entries are updated. Now LFSR is supported.
7265 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7266 * added pic16_newpCodeOpLit2 to support instructions with
7267 two literal arguments
7268 * pic16_pCode2str: corrected code that emits assembler instructions
7269 with two literal operands and those that have an access bit modifier
7270 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7271 this fixes a bug which caused some labels to be lost, when an
7272 assembler directive was added, i.e. banksel,
7273 * pic16_FixRegisterBanking: improved logic that causes the insertion
7275 * InlineFunction: functions that are called once, are not any more
7276 inlined. This can be a port option in the future,
7278 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7280 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7281 hold the corresponding uninitialized symbols,
7282 * pic16_allocProcessorRegister: registers have explicit marked the
7284 * pic16_allocInternalRegister: registers are explicit marked as
7286 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7287 processing list, so bit registers were lost,
7290 * ralloc.h: added field 'accessBank' and original symbol operand
7291 in register definition,
7292 * removed the field isMapped from register definition,
7294 ** Several functions have been removed from various sources:
7295 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7296 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7297 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7298 pic16_assignRelocatableRegisters
7300 ** others have been introduced:
7301 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7302 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7304 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7306 * support/scripts/inc2h.pl: changed definition of BIT_AT
7307 to emit 'sbit at' instead of 'bit at'. This was a request.
7309 PIC16 port related preliminary changes:
7310 * gen.c: prefixed function popRegFromString with
7311 pic16_ and all references to it corrected
7312 * pcode.c: all pic16_pc_* hardware registers prefixed
7313 with underscore (_),
7314 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7315 * ralloc.c: newReg(): when register is REG_SFR then
7316 set address to rIdx,
7317 pic16_allocProcessorRegister(): marks register wasUsed=0
7318 pic16_writeUsedRegs(): added a call to assign processor
7319 registers via pic16_assignFixedRegisters
7321 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7323 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7324 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7325 variables in unused register banks. Also the SSEG is placed
7326 wherever there is enough space for it, and IDATA can be anywhere
7327 in internal RAM. For now compile using -Wl-Y[stack_size].
7328 The mem file is different for this option as well, since it
7329 makes no sense of talking about DSEG lenght.
7331 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7333 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7334 in certain cases, e.g. when ROM assignment, patch provided
7335 from Albert den Haan.
7337 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7478 xdata and data memory on startup. Set the environment variable
7479 SDCC_NOGENRAMCLEAR to disable this.
7480 * src/mcs51/peephole.def,
7481 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
7482 (allows non-interrupt and interrupt code to safely compete for a resource
7483 without the non-interrupt code having to disable interrupts)
7485 2003-12-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7493 multiply defined with mismatching "at" address.
7495 2003-12-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7497 * src/ds390/main.c (PORT tininative_port): fixed bug #858416
7498 * src/SDCCglue.c (printChar, printIvalChar, emitStaticSeg),

8223 support for standard C idiom of memory mapped variables; for
8224 example, *((xdata int*)0x1234) = 1 is now internally equivalent
8225 to xdata int at 0x1234 tempvar = 1.
8226 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
8227 provided by Akiya ISHIDA

8243 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8245 Fixed bug #621531 (const & volatile confusion in the type chain).
8246 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
8247 refer to the const or volatile state of the pointer itself.

8325 * src/mcs51/gen.c (leftRightUseAcc),
8326 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
8327 iCode properly now. Use getSize instead of nRegs since a & b
8328 aren't part of the nRegs tally.
8330 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
8332 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()
8333 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
8334 before instructions that use the _STATUS register

8338 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
8339 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8340 fetching of the pointer
8341 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8342 copied from genNearPointerSet()
8343 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8344 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
8345 If they pop r0/r1 they must be called in the opposite order than aopOp().
8346 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
8347 (resp. --stack-auto), prepared for --xstack

8356 these ports have their own __sdcc_external_start()
8358 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8360 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8361 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8362 type for bits was changed. It resulted in bit variables becoming
8363 global, which is not permitted in PIC 14 assembly output.
8365 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8367 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8380 A few small changes that speed up the peephole optimizer.
8384 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8386 Try to make the peephole optimizer smarter by maintaining
8387 an association between the assembly source code and the
8388 iCodes that originated them. Put this information to use
8389 with a new peephole rule condition "notVolatile" so that
8390 the rules can be aggressive yet still safe.
8395 * src/mcs51/peeph.def
8397 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8401 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8402 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8403 if the left or right operand symbols have the accuse flag set.
8405 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8407 Changed the type of the result of the ! (NOT) operator to char;
8408 previously it returned the same type as the source. This allows
8409 us to eliminate all the genFloatNot functions (all of its target
8410 implementations were very buggy) since !float can use the same
8413 * src/SDCCicode.c (ast2iCode): ! returns char
8414 * src/mcs51/gen.c (genNot, genNotFloat),
8415 * src/ds390/gen.c (genNot, genNotFloat),
8416 * src/z80/gen.c (genNot, genNotFloat),
8417 * src/pic/gen.c (genNot, genNotFloat),

8420 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
8422 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8423 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8424 during interrupts. Ensure WSAVE is located at a shared bank address.
8425 2. Fixed page selection in some places
8426 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8427 the registers name strings.
8428 4. Fixed "signed / unsigned compare" compiler warnings.
8429 5. The PIC port manages its own allocation of the general purpose
8430 registers, but makes no attempt to reuse them. As a result when
8431 compiling it soon runs out of general purpose registers. Some
8432 additional code was added to the files pcode.c and device.c to walk
8433 through the function call tree and rename the registers so that they
8443 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8444 genPlus() & genMinus() when the result is the same as left or right
8446 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8450 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8452 Made bitfield a distinct type from bit so that bitfields
8453 convert as per ANSI C and bits retain their traditional
8454 boolean style behaviour. Implemented bitfield support in
8462 * src/ds390/gen.c: bit v bitfield split
8463 * src/z80/gen.c: New support for bitfields
8464 * support/regression/tests/bitfields.c: reenabled z80,
8467 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8469 Rules 246.x, 247.x relate to bitfields, the others speed up
8470 access to xdata mapped I/O devices.
8472 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8474 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8476 Cleaned up genPackBits and genUnpackBits and added two helper
8477 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8478 for literal assignments in genPackBits (thanks to Frieder for
8484 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8486 Fixed bug #748310 (pointer to function type mishandled when the
8487 function name is omitted). Also fixed a SIGSEGV when a function
8488 attribute (reentrant, etc) is used on a non-function or on a
8489 function but misplaced before the parameter list.
8491 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8493 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8494 * support/Util/SDCCerr.h,
8495 * support/Util/SDCCerr.c: Added func attr misuse error msg
8497 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
8499 Fixed bug #787649 by anonymous
8500 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
8501 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
8503 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8516 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8518 Made the constant following the "interrupt" keyword optional. If
8519 omitted, the function will not automatically be given an entry
8520 in the interrupt vector table (similar to #pragma NOIV, but
8521 less syntacticly kludgy). The interrupt number is also now
8522 range checked. Also fixed a bug in the high order bit example

9051 * src/SDCCmain.c: linkOptions is changed to set *,
9052 added if/endif conditional macros to remove options help
9053 messages from optionsTable when a port is not configured, added
9054 support for the PIc16 port in the ports table, when executing
9055 the compiler with no port specified on command line, a default
9056 port is selected with the new macro DEFAULT_PORT which is
9057 defined in port.h, in setDefaultOptions() linkOptions is removed
9058 from initialization assignment, since now it is a set,
9059 parseCmdLine uses setParseWithComma for linkOptions, in
9060 linkEdit() linkOptions are accessed with new function indexSet()
9061 which returns the i'th item of a set variable. See SDCCset.c, in
9062 linkEdit() when calling buildCmdLine(), added linkOptions as
9063 last argument. Now users can pass arguments to gplink via the
9064 -Wl option, main() uses pic16glue() to glue up pic16 programs

9078 gpasm complaining and test the linkage with gplink, _linkCmd and
9079 _asmCmd changed to be more gplink and gpasm friendly
9080 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9081 produced an error when parsed, peep rule 12 is added to utilize
9082 movff, but it is commented out since the pCode does not support
9083 yet a command with 2 address arguments

10142 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
10143 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
10145 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10146 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10148 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10150 * in \sdcc\as\mcs51\ changed these files in order to create an
10151 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10152 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10153 following files to include the previous two files: aslink.dsp,
10154 Makefile.aslink, Makefile.bcc, and Makefile.in.
10156 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10157 .adb instead of .cdb
10159 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10161 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10162 value from option --iram-size.
10164 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10166 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10169 2002-09-18 <wiml AT hhhh.org>
10171 * SDCClrange.h: exposed setFromRange() and setToRange()
10172 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10173 packRegsForAccUse() (bug 542397)
10174 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10175 multiple times and emitting the fetch operations more than once
10176 added aopGetUsesAcc() function to allow binary operators to
10177 fetch their operands in the correct order; made genMinus() emit
10178 compact code for X = LITERAL - Y
10180 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10181 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10182 sprintf() in line 1267.
10184 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10185 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10188 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10189 Changes to aslink (All the changes are marked with 'JCF'):
10191 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10194 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10195 area BSEG. Also moves, if possible, the DATA area down into the internal
10196 ram so more space is available.
10198 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10201 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10202 not bytes. Function summary() which creates a memory usage summary
10203 file with extension .mem. Reports of overlaping stack and small stack
10204 size. If the space for the stack is less than 16 bytes aslink trows a
10207 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10208 the 8051. Option 'y' for memory summary output file.
10210 Changes to sdcc (All the changes are marked with 'JCF'):
10212 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10214 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10215 overlaying area for it (uses RegBankUsed[4]).
10217 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10218 bank zero as used by default. By default aslink locates the stack
10219 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10220 the creation of the .mem file. Delegates the allocation of data area
10221 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10222 the begining of the stack area to aslink.
10224 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10225 glue() in SDCCglue.c creates an area for it.
10227 2002-09-03 Borut Razem <borut.razem AT siol.net>
10228 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10229 sdcc/src/pic/glue.c:
10230 introduced atexit() handler for teporay files removal in case of
10231 errors, assertions, ...
10233 2002-08-29 Borut Razem <borut.razem AT siol.net>
10234 * sdcc/support/cpp2/auto-host_vc_in.h:
10235 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10236 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10237 Maybe there is a similar problem with BORLANDC? It should be checked!
10239 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10240 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10241 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10242 was not executed, and the compiler (cl) launched a warning:
10243 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10245 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10246 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10248 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10249 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10251 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10252 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10253 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10254 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10255 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10256 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10257 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10258 - added Release configuration in VS projects
10259 - review of compiler an linker options
10260 - VC .exe files are generated in bin_vc directory, not to interfere
10261 with binaries generated from other projects (cygwin, mingw, bcc ...)
10263 * sdcc/src/yacc.dsp: added
10265 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10266 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10267 and insert the version number definitions from .version
10269 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10271 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10272 added - genarate auto-host.h using auto-host_vc_in.h as template
10275 removed from CVS, generated automatically
10277 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10278 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10280 2002-08-11 Borut Razem <borut.razem AT siol.net>
10281 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10283 2002-08-10 Borut Razem <borut.razem AT siol.net>
10284 * src/SDCCmain.c (main):
10285 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10286 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10287 The consequence was that some temporary files were not removed.
10290 unification of code in functions tempfilename() and tempfile():
10291 function tempnam() is defined in Visual Studio 6.0 and .NET
10293 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10295 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10296 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10297 - removed compiler command line option /WX: Treats all warnings as errors
10298 - update a list of source files, included into the project
10300 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10301 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10302 changed project type to Generic Project so that can be correcly converted to VS.NET project
10304 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10306 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10308 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10310 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10311 added return 0 statements after assert() to make compiler happy
10313 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10314 added newline in the def file to keep MSC compiler satisfied
10316 * sdcc/src/z80/gen.c:
10317 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10318 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10319 - solved MSC error in function aopDump()
10321 * sdcc_vc.h: define PREFIX as "\\sdcc"
10323 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10324 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10327 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10328 - Rewrote the register banking algorithm.
10329 - Added pCode live-range analysis to registers (for now, only non-used and
10330 singly-used registers optimized away)
10332 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10334 * 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.

10361 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10363 2002-03-28 Johan Knol <johan AT balder>
10365 * src/SDCCval.c: fixed bug #532436
10367 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10369 Added "char *Processor" field to the port structure.
10372 Added -p option. Allows port dependent processor to be specified.
10375 Initialized the new field char *Processor field to NULL in all ports
10378 Compiler generated registers for interrupt context saving
10379 were not getting allocated.
10381 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10384 Fixed left shift. Will promote the left side of a left shift
10385 if a) left shifting more than size of operand or b) when assigned
10386 to something size > size of left side
10388 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10390 tons of changes. Register allocation has been
10391 rewritten. Added customization for the various PICs. Flow
10392 analysis is restructured. ...
10394 * src/pic/device.h:
10397 * src/pic/device.c:
