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

330 * doc/Makefile: sync with nightly build makefile

336 fixes #1469504 and #1474602,
337 (pCodeRegOptimizeRegUsage): fixed typo in comment

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

600 the left operand is shorter than the result (c* = lit-c* + int),
602 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
605 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
607 * src/.version: increased version number to 2.5.5
608 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
609 linking is done manually in pic16 port's _linkEdit,
610 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
611 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
612 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
613 allocate asmop as AOP_ACC,
614 (aopForRemat): added parameter 'bool result' in function declaration,
615 (pic16_aopGet): return AOP_ACC when accessing WREG,

627 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
628 call to allocReg, not by manually allocating a new one,
629 (pic16_assignRegisters): now before going through the register
630 allocating functions mark all registers as free. This eliminates some
631 side effects resulting from peephole parser done earlier in the backbone
633 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

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

3034 * src/SDCCdflow.c (computeDataFlow),
3036 * src/SDCCloop.c (addDefInExprs, loopInvariants, loopOptimizations),
3038 * src/SDCCcflow.c (*),
3040 * src/SDCCBBlock.c (iCodeBreakDown, dumpEbbsToFileExt, eBBWithEntryLabel),
3041 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
3042 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
3043 immedDom() returning wrong block; probably fixes bug #1160833)
3045 2005-03-20 Borut Razem <borut.razem AT siol.net>
3047 * support/scripts/inc2h.pl: WIN32 port
3049 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
3051 * device/lib/makefile.in: added abs.c and labs.c
3053 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
3055 * device/include/stdint.h: added
3056 * device/lib/abs.c: added
3057 * device/lib/labs.c: added
3058 * device/include/stdlib.h: added abs() and labs() prototypes
3059 * device/lib/libsdcc.lib: added abs and labs
3060 * device/include/float.h,
3061 * device/lib/_fsmul.c,
3062 * device/lib/printf_fast.c,
3063 * device/lib/printf_tiny.c: updated comments
3065 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3067 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
3070 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3072 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
3073 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
3075 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3077 * device/lib/printf_large.c: removed inline assembly for portability and
3078 readability. Use printf_fast if speed or size are more important.
3079 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3080 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3082 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3084 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3085 prevent compiler warning
3087 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3089 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3090 moved to level 0 and declared as static. Also they are explicit
3091 placed in access bank. This was necessery because some times they
3092 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3093 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3094 optimizations. Currently only compare to unsigned char is implemented,
3095 * src/pic16/gen.c: added fReturnIdx array,
3096 * (struct resolvedIfx) is moved to gen.h and made public,
3097 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3098 * (aopForSym): added an optimization to directly store in stack of
3099 the operand of a SEND iCode,
3100 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3101 but as registers instead (AOP_REG) using the fReturnIdx array,
3102 * (pic16_freeAsmop): remove the freed register from the
3103 _G.sregsAlloc field,
3104 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3105 a compare of 'WREG',
3106 * (pic16_popGetTempRegCond): changed function prototype, now
3107 function takes also a bitVector argument v which holds the current
3108 set of registers that are allocated for stack access by aopForSym,
3109 registers allocated in aopForSym for accessing stack symbols are not
3110 any more part of the functions usedRegs field,
3111 * (genCall): some times aopOp is called for a stack variable to be
3112 send, aopForSym might perform the push, if this is true make sure
3113 that genCall doesn't push the variable twice by testing _G.resDirect,
3114 * (genFunction): changed testing for unspecified interrupt number
3115 from 256 to INTNO_UNSPEC,
3116 * modified selection scheme of frame pointer generation. Previously
3117 if function did use local registers a frame pointer was generated,
3118 now a frame pointer is generated only if function has arguments
3119 (that need PLUSW2 register access), or has stack arguments, or the
3120 compiler is not instructed to omit the frame pointer,
3121 * (genEndFunction): before restoring local registers that were saved
3122 in the function preamble, also restore the registers that *might*
3123 have been allocated for stack access,
3124 * (genRet): removed some old comments,
3125 * (genCmp, the active (RN's) version): added a call to the
3126 pic16_genCmp_special function to perform the compare with a more
3127 robust and optimized way,
3128 * (genInline): a feature has been added in inline code generation,
3129 which allows a wildcard variable substitution when writing inline
3130 assembly. Code is incomplete and experimental therefore undocumented,
3131 * (genCast): changed order of aopOp for result and right to allow
3132 aopForSym to directly load the result if possible,
3133 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3134 perform an optimized compare on some selected special occasions,
3135 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3136 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3137 generate an IVT any more,
3138 * src/pic16/main.c (pic16_optionsTable): added command line option
3140 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3141 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3143 * src/pic16/NOTES: Raphael Neider added in list of active developers
3144 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3145 jumptable_end to prevent bug #,
3146 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3147 inCond and outCond fields,
3148 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3149 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3150 turn off register spilling,
3151 * (packRegsForOneUse): synced with other ports' versions although it
3152 is not used currently,
3153 * (pic16_packRegisters): added an optimization while reading
3154 structure bitfields, some registers may be saved (malloc code is
3155 decreased by 80 bytes)
3157 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3159 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3160 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3161 this can be optimized more?
3163 2005-03-10 Raphael Neider <rneider AT web.de>
3165 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3166 genNearPointerGet): (hopefully) fixed access to bitfields via
3167 pointers (p->bitN = x; and x = p->bitN; failed)
3169 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3212 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
3213 to keep the correct label reference count when adding/removing references
3214 to labels. A peephole file using this is appended to patch #1144962.

3357 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
3358 this might fix SIGSEGVs on MinGW...

3447 * (genNearPointer[GS]et): enforce reloading of FSR0 (was still
3448 used uninitialized in some cases)

3450 copy the third byte from the int -- now assumes 0x80 (data memory)
3451 * src/pic16/genarith.c (pic16_genPlus): fixed bug when swapping
3452 operands (genAddLit expects the iCode's operands to swapped as

3801 Adding support for replacing ljmps with sjmps in jumptables
3802 generated for switch statements. For now you need to set the
3803 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3804 Now 4 algorithms for mcs51 jumptable generation are used:
3805 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3806 addresses loaded pc-relative for up to 112 cases and stack-pushing
3807 target addresses loaded with offset from dptr for up to 256 cases.

3837 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3839 * added libc directory. The current version of LibC contains string
3840 functions, ctype functions and macros and some functions of the
3841 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3842 be extensively tested in the future. Standard disclaimer here.
3843 Library is not automatically build yet. But one can build it by
3844 invoking 'make' inside the libc directory.

3855 * (pic16_storeForReturn): optimized return of 0,
3856 * (genCmp): experimental code for new genCmp which uses PIC18's
3857 special compare&skip instructions. Initial tests fail some times
3858 with variables grater than 1 byte in size, so new code is disabled,
3859 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3861 * (genCast): began a fix to optimize the casting of a bit to another
3862 bit, now assigning a bitfield to another bitfield will fail, sorry,

3870 * (isBankInstruction): modified to return 0 for no banking instruction,
3871 and 1 for banking instruction,
3872 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3873 caused stop processing pCodes after a inline assembly block,
3874 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

3876 registers when it shouldn't,
3877 * src/pic16/ralloc.c (allocReg): add preliminary support for
3878 supporting a limited set of temporary registers,
3880 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3882 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,

3886 (genFunction): optimize RECEIVE iCodes in reentrant functions
3888 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3890 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

3899 * device/lib/_gptrget.c (_gptrget),
3900 * device/lib/_gptrgetc.c (_gptrgetc),

6885 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6887 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6888 loaded with the linker search paths (-L arguments) and the libraries
6889 to be linked with the current source (-l arguments). Changes
6890 currently will affect only the pic16 port.
6891 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6892 include path the port specific paths and port specific libraries,
6893 * gplink command now contains the $3 argument,
6894 * src/pic16/device.h,
6895 * src/pic16/device.c,: structure PIC_device is made public and
6896 renamed to PIC16_device, the same for variable Pics which is renamed

6911 Documenting changes from previous commits.
6912 * configure.in (version 1.56),
6913 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6914 when generating output files to configure the pic16 library,
6915 but now I've commented it out, since gputils aren't installed in the
6916 SF compile farm, so library won't compile
6918 * device/lib/Makefile.in (version 1.56): initially I've added in
6919 target 'all' the prerequestive 'model-pic16' so it compiled the
6920 pic16 library, but now I've commented it out for the same reasons
6922 * added targets 'model-pic16' and 'objects-pic16' to compile the
6924 * added target 'port-specific-objects-pic16' to handle the
6925 generated libraries and copy them into the build/ directory
6926 * added target 'clean-intermediate-pic16' to clean intermediate
6927 files into pic16 directory
6928 * in target 'installdirs' added line to create directory pic16 in
6929 the installation path

6932 added lines to copy all header files to installation path,
6933 * in target 'installdirs' added line create directory for pic16
6934 headers in the installation path

6950 option so that it actually works. Made it specific to the z80, since
6951 the gbz80 doesn't have these kinds of I/O ports.
6953 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6955 * device/include/z180.h,

6979 via literal number. The symbol is placed in the corresponding
6980 position of the data ram
6981 * (pic16_dump_section): relocatable and absolute uninitialized
6982 data are now emitted in sorted order to reduce section naming,
6983 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6984 weren't marked as being in the access bank,
6986 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6988 Added portion of GNU PIC Library under the directory
6989 device/include/pic16 and device/lib/pic16. These files
6990 contain the declarations of SFRs for the PIC18Fxx2 devices.
6991 The directory is initialized via configure from toplevel.

7020 * doc/sdccman.lyx: Moved and added some sections, small changes
7021 all over. Telling LaTeX to be less strict with word spacing
7022 to better keep the right margin. Changed some notes about
7023 maintainance of the ports in section 3.2.1 - is it OK like this?
7025 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
7027 SDCC source changes:
7028 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

7063 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7065 * src/pic16/peeph.def: all peepholes with movff are commented out,
7066 because there is a problem in the pcode peep optimizer,
7067 * src/pic16/ralloc.c: the register allocator can now reuse local

7160 include information about variables allocated to the overlay
7163 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7165 * as/mcs51/lkmain.c: Help about -Y option

7177 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7179 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7180 (default behaviour).
7182 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7184 A python script to validate compiler diagnostic messages. It can be
7185 used to verify that sdcc complains about bad c source code and
7186 gives a good location of the error.
7187 * support/valdiag/Makefile,
7188 * support/valdiag/valdiag.py,
7189 * support/valdiag/tests/*
7191 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7205 around the header file.
7206 Bug reported from Jesus Calvino-Fraga
7208 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7210 * sdcc.spec: updated
7211 * device/include/Makefile.in: don't install CVS directories
7212 * device/lib/Makefile.in: added removal of CVS directories after install
7213 * doc/Makefile: fixed install, added local_icons
7214 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7215 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7216 * src/ds390/gen.c (genRightShift): fixed bug #870788
7217 * src/SDCCast.c (decorateType): fixed bug #870781
7219 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7221 PIC16 port related changes:
7222 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7223 added variable stackPos,
7225 * gen.c: genCall, assignResultValue: added support for
7226 pushing/retrieving function parameters to/from stack,
7227 genFunction,genEndFunction: setup stack frame for the
7229 genAddrOf: will be changed according to bug 863624
7231 * added files genutils.c and genutils.h which contain gen*
7232 debugged and optimised functions extracted from gen.c
7234 * glue.c: added variable 'externs' which holds extern symbols,
7235 pic16emitRegularMap: is modified to properly handle relocatable
7236 symbols under the new scheme,
7237 pic16createInterruptVect: is modified
7238 pic16printPublics: is modified to emit 'global' assembler directives,
7239 added pic16_printExterns to print extern symbols,
7240 pic16glue: initializes stack/frame pointer in the beginning of
7241 the assembly output. Temporary hack, will be corrected later,
7242 because gplink yet does not support stack and SDCC does not
7243 yet support a type of crt0.o object to create the final binary.
7245 * Removed many lines that contain 8051 legacy code.
7246 * The code is finally placed under a 'code' directive.
7247 * Added port specific options.
7249 * _process_pragma: simplified since now we do not need *special*
7250 include file to define SFR registers. But a separate header
7251 will be needed. This will be developed later.
7252 * _pic16_parseOptions: added, parses port specific options:
7253 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7254 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7255 --preplace-udata-with=
7257 * _pic16_setDefaultOptions: modified to initialize section names,
7258 but hack is temporarly out of order since it needs improvement.
7259 * _pic16_genAssemblerPreamble: configuration words are emitted by
7260 their address instead of their name. This part is incomplete and
7261 supports only the 18Fxx2 devices. Other devices will emit an error
7262 during assembly since they do not contain the same set of config
7264 * _pic16_genIVT: is modified,
7266 * pcode.c: added definitions for some hardware registers that are needed
7268 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7269 All PCI entries are updated. Now LFSR is supported.
7270 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7271 * added pic16_newpCodeOpLit2 to support instructions with
7272 two literal arguments
7273 * pic16_pCode2str: corrected code that emits assembler instructions
7274 with two literal operands and those that have an access bit modifier
7275 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7276 this fixes a bug which caused some labels to be lost, when an
7277 assembler directive was added, i.e. banksel,
7278 * pic16_FixRegisterBanking: improved logic that causes the insertion
7280 * InlineFunction: functions that are called once, are not any more
7281 inlined. This can be a port option in the future,
7283 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7285 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7286 hold the corresponding uninitialized symbols,
7287 * pic16_allocProcessorRegister: registers have explicit marked the
7289 * pic16_allocInternalRegister: registers are explicit marked as
7291 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7292 processing list, so bit registers were lost,
7295 * ralloc.h: added field 'accessBank' and original symbol operand
7296 in register definition,
7297 * removed the field isMapped from register definition,
7299 ** Several functions have been removed from various sources:
7300 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7301 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7302 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7303 pic16_assignRelocatableRegisters
7305 ** others have been introduced:
7306 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7307 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7309 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7311 * support/scripts/inc2h.pl: changed definition of BIT_AT
7312 to emit 'sbit at' instead of 'bit at'. This was a request.
7314 PIC16 port related preliminary changes:
7315 * gen.c: prefixed function popRegFromString with
7316 pic16_ and all references to it corrected
7317 * pcode.c: all pic16_pc_* hardware registers prefixed
7318 with underscore (_),
7319 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7320 * ralloc.c: newReg(): when register is REG_SFR then
7321 set address to rIdx,
7322 pic16_allocProcessorRegister(): marks register wasUsed=0
7323 pic16_writeUsedRegs(): added a call to assign processor
7324 registers via pic16_assignFixedRegisters
7326 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7328 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7329 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7330 variables in unused register banks. Also the SSEG is placed
7331 wherever there is enough space for it, and IDATA can be anywhere
7332 in internal RAM. For now compile using -Wl-Y[stack_size].
7333 The mem file is different for this option as well, since it
7334 makes no sense of talking about DSEG lenght.
7336 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7338 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7339 in certain cases, e.g. when ROM assignment, patch provided
7340 from Albert den Haan.
7342 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7485 * src/mcs51/peephole.def,
7486 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
7487 (allows non-interrupt and interrupt code to safely compete for a resource

8365 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8366 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8367 type for bits was changed. It resulted in bit variables becoming

8385 A few small changes that speed up the peephole optimizer.
8389 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8391 Try to make the peephole optimizer smarter by maintaining
8392 an association between the assembly source code and the
8393 iCodes that originated them. Put this information to use
8394 with a new peephole rule condition "notVolatile" so that
8395 the rules can be aggressive yet still safe.
8400 * src/mcs51/peeph.def
8402 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8406 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8407 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8408 if the left or right operand symbols have the accuse flag set.
8410 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8412 Changed the type of the result of the ! (NOT) operator to char;
8413 previously it returned the same type as the source. This allows
8414 us to eliminate all the genFloatNot functions (all of its target
8415 implementations were very buggy) since !float can use the same
8418 * src/SDCCicode.c (ast2iCode): ! returns char

8420 * src/ds390/gen.c (genNot, genNotFloat),
8421 * src/z80/gen.c (genNot, genNotFloat),
8422 * src/pic/gen.c (genNot, genNotFloat),

8425 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
8427 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8428 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8429 during interrupts. Ensure WSAVE is located at a shared bank address.
8430 2. Fixed page selection in some places
8431 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8432 the registers name strings.
8433 4. Fixed "signed / unsigned compare" compiler warnings.
8434 5. The PIC port manages its own allocation of the general purpose
8435 registers, but makes no attempt to reuse them. As a result when
8436 compiling it soon runs out of general purpose registers. Some
8437 additional code was added to the files pcode.c and device.c to walk
8438 through the function call tree and rename the registers so that they
8448 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8449 genPlus() & genMinus() when the result is the same as left or right

8455 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8457 Made bitfield a distinct type from bit so that bitfields
8458 convert as per ANSI C and bits retain their traditional
8459 boolean style behaviour. Implemented bitfield support in
8467 * src/ds390/gen.c: bit v bitfield split
8468 * src/z80/gen.c: New support for bitfields
8469 * support/regression/tests/bitfields.c: reenabled z80,
8472 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8474 Rules 246.x, 247.x relate to bitfields, the others speed up
8475 access to xdata mapped I/O devices.
8477 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8479 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8481 Cleaned up genPackBits and genUnpackBits and added two helper
8482 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8483 for literal assignments in genPackBits (thanks to Frieder for
8489 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8491 Fixed bug #748310 (pointer to function type mishandled when the
8492 function name is omitted). Also fixed a SIGSEGV when a function
8493 attribute (reentrant, etc) is used on a non-function or on a
8494 function but misplaced before the parameter list.

8523 Made the constant following the "interrupt" keyword optional. If
8524 omitted, the function will not automatically be given an entry
8525 in the interrupt vector table (similar to #pragma NOIV, but
8526 less syntacticly kludgy). The interrupt number is also now
8527 range checked. Also fixed a bug in the high order bit example
8534 * support/Util/SDCCerr.c
8535 * support/Util/SDCCerr.h
8538 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

8548 unsigned, but are signed by default
8549 * src/SDCCval.c (constVal): rearranged
8550 * src/SDCCval.c (valMod): preliminary fix
8551 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8594 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
8595 * src/SDCCval.c (valDiv, valMod): fixed signdness
8596 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
8597 signedness of modulo, left and right shift
8598 * support/Util/SDCCerr.c: added warning "integer overflow in expression"

9059 support for the PIc16 port in the ports table, when executing
9060 the compiler with no port specified on command line, a default
9061 port is selected with the new macro DEFAULT_PORT which is
9062 defined in port.h, in setDefaultOptions() linkOptions is removed
9063 from initialization assignment, since now it is a set,
9064 parseCmdLine uses setParseWithComma for linkOptions, in
9065 linkEdit() linkOptions are accessed with new function indexSet()
9066 which returns the i'th item of a set variable. See SDCCset.c, in
9067 linkEdit() when calling buildCmdLine(), added linkOptions as
9068 last argument. Now users can pass arguments to gplink via the

10147 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
10148 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
10150 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10151 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10153 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10155 * in \sdcc\as\mcs51\ changed these files in order to create an
10156 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10157 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10158 following files to include the previous two files: aslink.dsp,
10159 Makefile.aslink, Makefile.bcc, and Makefile.in.
10161 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10162 .adb instead of .cdb
10164 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10166 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10167 value from option --iram-size.
10169 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10171 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10174 2002-09-18 <wiml AT hhhh.org>
10176 * SDCClrange.h: exposed setFromRange() and setToRange()
10177 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10178 packRegsForAccUse() (bug 542397)
10179 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10180 multiple times and emitting the fetch operations more than once
10181 added aopGetUsesAcc() function to allow binary operators to
10182 fetch their operands in the correct order; made genMinus() emit
10183 compact code for X = LITERAL - Y
10185 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10186 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10187 sprintf() in line 1267.
10189 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10190 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10193 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10194 Changes to aslink (All the changes are marked with 'JCF'):
10196 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10199 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10200 area BSEG. Also moves, if possible, the DATA area down into the internal
10201 ram so more space is available.
10203 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10206 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10207 not bytes. Function summary() which creates a memory usage summary
10208 file with extension .mem. Reports of overlaping stack and small stack
10209 size. If the space for the stack is less than 16 bytes aslink trows a
10212 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10213 the 8051. Option 'y' for memory summary output file.
10215 Changes to sdcc (All the changes are marked with 'JCF'):
10217 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10219 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10220 overlaying area for it (uses RegBankUsed[4]).
10222 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10223 bank zero as used by default. By default aslink locates the stack
10224 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10225 the creation of the .mem file. Delegates the allocation of data area
10226 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10227 the begining of the stack area to aslink.
10229 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10230 glue() in SDCCglue.c creates an area for it.
10232 2002-09-03 Borut Razem <borut.razem AT siol.net>
10233 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10234 sdcc/src/pic/glue.c:
10235 introduced atexit() handler for teporay files removal in case of
10236 errors, assertions, ...
10238 2002-08-29 Borut Razem <borut.razem AT siol.net>
10239 * sdcc/support/cpp2/auto-host_vc_in.h:
10240 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10241 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10242 Maybe there is a similar problem with BORLANDC? It should be checked!
10244 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10245 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10246 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10247 was not executed, and the compiler (cl) launched a warning:
10248 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10250 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10251 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10253 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10254 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10256 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10257 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10258 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10259 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10260 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10261 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10262 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10263 - added Release configuration in VS projects
10264 - review of compiler an linker options
10265 - VC .exe files are generated in bin_vc directory, not to interfere
10266 with binaries generated from other projects (cygwin, mingw, bcc ...)
10268 * sdcc/src/yacc.dsp: added
10270 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10271 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10272 and insert the version number definitions from .version
10274 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10276 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10277 added - genarate auto-host.h using auto-host_vc_in.h as template
10280 removed from CVS, generated automatically
10282 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10283 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10285 2002-08-11 Borut Razem <borut.razem AT siol.net>
10286 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10288 2002-08-10 Borut Razem <borut.razem AT siol.net>
10289 * src/SDCCmain.c (main):
10290 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10291 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10292 The consequence was that some temporary files were not removed.
10295 unification of code in functions tempfilename() and tempfile():
10296 function tempnam() is defined in Visual Studio 6.0 and .NET
10298 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10300 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10301 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10302 - removed compiler command line option /WX: Treats all warnings as errors
10303 - update a list of source files, included into the project
10305 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10306 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10307 changed project type to Generic Project so that can be correcly converted to VS.NET project
10309 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10311 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10313 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10315 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10316 added return 0 statements after assert() to make compiler happy
10318 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10319 added newline in the def file to keep MSC compiler satisfied
10321 * sdcc/src/z80/gen.c:
10322 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10323 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10324 - solved MSC error in function aopDump()
10326 * sdcc_vc.h: define PREFIX as "\\sdcc"
10328 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10329 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
10331 2002-06-22 Scott Dattalo <scott AT dattalo.com>
10332 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10333 - Rewrote the register banking algorithm.
10334 - Added pCode live-range analysis to registers (for now, only non-used and
10335 singly-used registers optimized away)
10337 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10339 * 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.

10362 * src/z80/main.c: Added force callee saves for jaune.
10364 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
10366 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10368 2002-03-28 Johan Knol <johan AT balder>
10370 * src/SDCCval.c: fixed bug #532436
10372 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10374 Added "char *Processor" field to the port structure.
10377 Added -p option. Allows port dependent processor to be specified.
10380 Initialized the new field char *Processor field to NULL in all ports
10383 Compiler generated registers for interrupt context saving
10384 were not getting allocated.
10386 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10389 Fixed left shift. Will promote the left side of a left shift
10390 if a) left shifting more than size of operand or b) when assigned
10391 to something size > size of left side
10393 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10395 tons of changes. Register allocation has been
10396 rewritten. Added customization for the various PICs. Flow
