409 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
411 Enabled VPATH feature: changed nearly all Makefiles (149 files).
412 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
414 One basic decision: e.g. src/clean.mk includes further files. In order
415 to make this work there are two solutions:
416 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
417 run configure on them. This way they can use
418 'include $(srcdir)/port-clean.mk'
419 - always include clean.mk by the Makefile at the same level. To avoid
420 that `make clean` tries to include and build Makefile.dep the
421 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
422 implemented, because now even `make uninstall` doesn't create
423 Makefile.in. clean.mk could be eliminated by pasting it in
426 * debugger/mcs51/Makefile.in: build own objects from library sources
427 (SLIB, SDCC) in current directory
429 * configure, configure.in: renamed --disable-device-lib-build in
430 --disable-device-lib; added --enable-doc, the required tools are
431 searched by configure; added result message; the toolchain for the
432 belonging ports are now only built, if the port is enabled.
434 * support/regression/*: all output is written in directory gen, because
435 the fwk and ports directories don't livet in the build tree using vpath
437 * doc/sdccman.lyx: renamed --disable-device-lib-build to
438 --disable-device-lib, added --enable-doc, added section VPATH
440 * sim/ucsim/configure.in,
441 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
442 z80 are enabled by default
444 2006-04-24 Raphael Neider <rneider AT web.de>
446 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
447 to config word, "pic14_"-prefixed some extern functions
448 (pic14_emitConfigWord): emit __config directive(s) if assignment to
449 config word has been found
450 * src/pic/device.h: added prototypes
451 * src/pic/pcode.c: added "pic14_"-prefix where needed
452 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
454 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
456 (pic14emitRegularMap): ignore config words,
457 (pic14createInterruptVect): moved generating __config directives away
458 (picglue): have __config directives emitted
460 2006-04-24 Borut Razem <borut.razem AT siol.net>
462 * doc/Makefile: sync with nightly build makefile
464 2006-04-24 Raphael Neider <rneider AT web.de>
466 * src/pic/pcoderegs.c (OptimizeRegUsage): do not optimize
467 registers that have not been assigned proper liveranges,
468 fixes #1469504 and #1474602,
469 (pCodeRegOptimizeRegUsage): fixed typo in comment
471 2006-04-24 Borut Razem <borut.razem AT siol.net>
473 * device/examples/main8051.c: deleted - it was removed from CVS
474 24.mar.2000 and after that modified 18.feb.2001, so it reappered
475 after the transition to Subversion
476 * src/SDCCalloc.h: deleted - it was removed from CVS
477 3.feb.2001 and after that modified 18.feb.2001, so it reappered
478 after the transition to Subversion

734 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
737 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
739 * src/.version: increased version number to 2.5.5
740 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
741 linking is done manually in pic16 port's _linkEdit,
742 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
743 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,

759 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
760 call to allocReg, not by manually allocating a new one,
761 (pic16_assignRegisters): now before going through the register
762 allocating functions mark all registers as free. This eliminates some
763 side effects resulting from peephole parser done earlier in the backbone

823 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
824 which dumps before the function entry point a data byte which represents
825 the number of the local variables used by the specified function, added
826 'xinst' for initial support for Extended Instruction Support,
827 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,

829 port->fun_prefix anymore (may change later),
830 (genFunction, genEndFunction): do not store/restore local registers for
831 _main (this should take care the --main-return command line option in
833 (genOr): removed some legacy pic-port instructions,
834 * src/pic16/genarith.c (genAddLit): re-enabled old code because
835 performing operations with SFR's causes data to be written more than
836 once to each SFR. Perhaps SFRs should be handled in special cases...
837 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
839 * src/pic16/main.c (_process_pragma): stack bound checking did not take
840 into account for stack starting position,
841 (struct OPTIONS pic16_optionsTable): added command line argument
842 --extended or -y for Extended Instruction Support,
843 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
844 (deassignLRs): *** perhaps the most important change, old 'for' code
845 (commented out for reference), didn't account for some registers which
846 were left marked 'not free' after a pointer operation. The change
847 reduces register usage a lot in some cases

3207 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3209 * device/lib/printf_large.c: removed inline assembly for portability and
3210 readability. Use printf_fast if speed or size are more important.
3211 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3212 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3214 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3216 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3217 prevent compiler warning
3219 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3221 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3222 moved to level 0 and declared as static. Also they are explicit
3223 placed in access bank. This was necessery because some times they
3224 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3225 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3226 optimizations. Currently only compare to unsigned char is implemented,
3227 * src/pic16/gen.c: added fReturnIdx array,
3228 * (struct resolvedIfx) is moved to gen.h and made public,
3229 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3230 * (aopForSym): added an optimization to directly store in stack of
3231 the operand of a SEND iCode,
3232 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3233 but as registers instead (AOP_REG) using the fReturnIdx array,
3234 * (pic16_freeAsmop): remove the freed register from the
3235 _G.sregsAlloc field,
3236 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3237 a compare of 'WREG',
3238 * (pic16_popGetTempRegCond): changed function prototype, now
3239 function takes also a bitVector argument v which holds the current
3240 set of registers that are allocated for stack access by aopForSym,
3241 registers allocated in aopForSym for accessing stack symbols are not
3242 any more part of the functions usedRegs field,
3243 * (genCall): some times aopOp is called for a stack variable to be
3244 send, aopForSym might perform the push, if this is true make sure
3245 that genCall doesn't push the variable twice by testing _G.resDirect,
3246 * (genFunction): changed testing for unspecified interrupt number
3247 from 256 to INTNO_UNSPEC,
3248 * modified selection scheme of frame pointer generation. Previously
3249 if function did use local registers a frame pointer was generated,
3250 now a frame pointer is generated only if function has arguments
3251 (that need PLUSW2 register access), or has stack arguments, or the
3252 compiler is not instructed to omit the frame pointer,
3253 * (genEndFunction): before restoring local registers that were saved
3254 in the function preamble, also restore the registers that *might*
3255 have been allocated for stack access,
3256 * (genRet): removed some old comments,
3257 * (genCmp, the active (RN's) version): added a call to the
3258 pic16_genCmp_special function to perform the compare with a more
3259 robust and optimized way,
3260 * (genInline): a feature has been added in inline code generation,
3261 which allows a wildcard variable substitution when writing inline
3262 assembly. Code is incomplete and experimental therefore undocumented,
3263 * (genCast): changed order of aopOp for result and right to allow
3264 aopForSym to directly load the result if possible,
3265 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3266 perform an optimized compare on some selected special occasions,
3267 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3268 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3269 generate an IVT any more,
3270 * src/pic16/main.c (pic16_optionsTable): added command line option
3272 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3273 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3275 * src/pic16/NOTES: Raphael Neider added in list of active developers
3276 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3277 jumptable_end to prevent bug #,
3278 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3279 inCond and outCond fields,
3280 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3281 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3282 turn off register spilling,
3283 * (packRegsForOneUse): synced with other ports' versions although it
3284 is not used currently,
3285 * (pic16_packRegisters): added an optimization while reading
3286 structure bitfields, some registers may be saved (malloc code is
3287 decreased by 80 bytes)
3289 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3291 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3292 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3293 this can be optimized more?
3295 2005-03-10 Raphael Neider <rneider AT web.de>
3297 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3298 genNearPointerGet): (hopefully) fixed access to bitfields via
3299 pointers (p->bitN = x; and x = p->bitN; failed)

3916 (setFromConditionArgs): friendly operand parser for peephole rules,
3917 (operandBaseName, operandsNotRelated): new peephole condition
3918 "operandsNotRelated" -- similar to "operandsNotSame", but takes

3931 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3933 Adding support for replacing ljmps with sjmps in jumptables
3934 generated for switch statements. For now you need to set the
3935 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3936 Now 4 algorithms for mcs51 jumptable generation are used:
3937 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3938 addresses loaded pc-relative for up to 112 cases and stack-pushing
3939 target addresses loaded with offset from dptr for up to 256 cases.

3966 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
3967 to call when a stack overflow occurs,
3968 * (malloc.h): added CVS Id tag,
3969 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3971 * added libc directory. The current version of LibC contains string
3972 functions, ctype functions and macros and some functions of the
3973 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3974 be extensively tested in the future. Standard disclaimer here.
3975 Library is not automatically build yet. But one can build it by
3976 invoking 'make' inside the libc directory.
3977 * added ADC library under libio. Preliminary version yet.
3979 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

3986 * (genUminusFloat): fixed for pic16, ported code from mcs51,
3987 * (pic16_storeForReturn): optimized return of 0,
3988 * (genCmp): experimental code for new genCmp which uses PIC18's
3989 special compare&skip instructions. Initial tests fail some times
3990 with variables grater than 1 byte in size, so new code is disabled,
3991 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3993 * (genCast): began a fix to optimize the casting of a bit to another
3994 bit, now assigning a bitfield to another bitfield will fail, sorry,
3995 * src/pic16/main.c: disabled the use of lr-support feature,
3996 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
3997 * added some function prototypes, added function _debugf prototype,

3999 bits with offset (case PO_GPR_BIT),
4000 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
4002 * (isBankInstruction): modified to return 0 for no banking instruction,
4003 and 1 for banking instruction,
4004 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4005 caused stop processing pCodes after a inline assembly block,
4006 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4007 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4008 registers when it shouldn't,
4009 * src/pic16/ralloc.c (allocReg): add preliminary support for
4010 supporting a limited set of temporary registers,
4012 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4014 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4015 genDataPointerSet): ensure assignments always copy in MSB to LSB
4017 (loadRegFromAop): recognize CLRH optimization,
4018 (genFunction): optimize RECEIVE iCodes in reentrant functions
4020 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4022 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
4023 --out-fmt-s19 turning into --out-fmt-elf if s19 was already

4036 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
4038 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

7017 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7019 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7020 loaded with the linker search paths (-L arguments) and the libraries
7021 to be linked with the current source (-l arguments). Changes
7022 currently will affect only the pic16 port.
7023 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7024 include path the port specific paths and port specific libraries,
7025 * gplink command now contains the $3 argument,
7026 * src/pic16/device.h,
7027 * src/pic16/device.c,: structure PIC_device is made public and
7028 renamed to PIC16_device, the same for variable Pics which is renamed
7029 to Pics16. Updated all references to them.
7030 * src/pic16/glue.c (pic16glue): corrected bug with code
7031 initialization which bypassed the variable initializations block.
7033 * device/lib/pic16/Makefile.rules: removed --penable-stack from

7041 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
7043 Documenting changes from previous commits.
7044 * configure.in (version 1.56),
7045 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7046 when generating output files to configure the pic16 library,
7047 but now I've commented it out, since gputils aren't installed in the
7048 SF compile farm, so library won't compile
7050 * device/lib/Makefile.in (version 1.56): initially I've added in
7051 target 'all' the prerequestive 'model-pic16' so it compiled the
7052 pic16 library, but now I've commented it out for the same reasons
7054 * added targets 'model-pic16' and 'objects-pic16' to compile the
7056 * added target 'port-specific-objects-pic16' to handle the
7057 generated libraries and copy them into the build/ directory
7058 * added target 'clean-intermediate-pic16' to clean intermediate
7059 files into pic16 directory
7060 * in target 'installdirs' added line to create directory pic16 in
7061 the installation path
7063 * device/include/Makefile.in (version 1.11): in target 'install'
7064 added lines to copy all header files to installation path,
7065 * in target 'installdirs' added line create directory for pic16
7066 headers in the installation path
7068 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

7081 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7082 option so that it actually works. Made it specific to the z80, since
7083 the gbz80 doesn't have these kinds of I/O ports.
7085 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7087 * device/include/z180.h,

7100 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7102 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
7103 changed interrupt vector table generation to only emit declared vectors.
7104 * device/include/Makefile.in: added missing backslash
7105 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
7107 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7109 Mainly changes to support compilation of the device libraries
7110 * src/pic16/device.c: stack is allocated via symbol and not
7111 via literal number. The symbol is placed in the corresponding
7112 position of the data ram
7113 * (pic16_dump_section): relocatable and absolute uninitialized
7114 data are now emitted in sorted order to reduce section naming,
7115 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7116 weren't marked as being in the access bank,
7118 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7120 Added portion of GNU PIC Library under the directory
7121 device/include/pic16 and device/lib/pic16. These files
7122 contain the declarations of SFRs for the PIC18Fxx2 devices.
7123 The directory is initialized via configure from toplevel.
7125 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
7127 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
7128 the spilllocations to be compared correctly
7130 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
7132 * src/SDCCast.c (decorateType): fixed bug introduced today
7134 2004-01-12 Borut Razem <borut.razem AT siol.net>
7136 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

7139 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
7141 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
7142 in simpler and even better code
7144 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
7146 * src/SDCCicode.c (operandOperation): fixed bug #874819

7150 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7152 * doc/sdccman.lyx: Moved and added some sections, small changes
7153 all over. Telling LaTeX to be less strict with word spacing
7154 to better keep the right margin. Changed some notes about
7155 maintainance of the ports in section 3.2.1 - is it OK like this?
7157 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
7159 SDCC source changes:
7160 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

7193 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
7194 UPPER for immediate operands,
7195 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7197 * src/pic16/peeph.def: all peepholes with movff are commented out,
7198 because there is a problem in the pcode peep optimizer,
7199 * src/pic16/ralloc.c: the register allocator can now reuse local
7200 function symbols for another function. This saves register usage.
7201 * src/pic16/ralloc.h: added flag isLocal in structure regs,
7203 Added file src/pic16/NOTES with information about program writing on
7204 the current port version.

7213 * src/SDCCmain.c : fixed #872250: -l command line defined library
7214 files are scanned before standard library files
7216 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7232 * src/mcs51/gen.c (genFunction, genEndFunction, genReceive, getTempRegs,
7233 gen51Code): more efficient parameter receive for --model-large
7236 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7239 * src/z80/main.c: added missed needLinkerScript flags (more than
7240 one port structure defined in these file)
7241 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed
7244 2004-01-08 Vangelis Rokas <vrokas AT otenet.gr>

7257 needLinkerScript flag
7259 * src/pic16/gen.c (genAddrOf): fixed bug #863624
7260 * src/pic/glue.c: added variable udata_section_name to
7261 override default uninitialized data segment definition for
7262 devices only with SHAREBANK memory (reported from Erik Epetrich)
7263 * (pic14emitOverlay): modified to emit a commented overlay segment
7264 directive when no overlay data exist
7265 * (picglue): modified to emit uninitialized data segment
7266 according to udata_section_name

7271 arguments via -W option
7272 * src/pic16/main.c: added $l in _asmCmd, changed extension for
7273 object file from '.rel' to '.o' in port->linker structure,
7274 changed size of fptr from 2 to 3 in port structure
7276 2004-01-07 Borut Razem <borut.razem AT siol.net>
7278 * support/scripts/sdcc.nsi: update PATH
7279 * support/scripts/sdcc.ico: craeted
7281 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>
7283 * device/include/Makefile.in: fix install
7284 * doc/Makefile: fix install
7286 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7288 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
7290 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

7292 include information about variables allocated to the overlay
7295 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7297 * as/mcs51/lkmain.c: Help about -Y option

7309 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7311 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7312 (default behaviour).
7314 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7316 A python script to validate compiler diagnostic messages. It can be
7317 used to verify that sdcc complains about bad c source code and
7318 gives a good location of the error.
7319 * support/valdiag/Makefile,
7320 * support/valdiag/valdiag.py,
7321 * support/valdiag/tests/*
7323 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7325 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
7326 * src/SDCCsymt.c (newEnumType),

7334 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7336 * src/common.h: added ifndef/define/endif macros
7337 around the header file.
7338 Bug reported from Jesus Calvino-Fraga
7340 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7342 * sdcc.spec: updated
7343 * device/include/Makefile.in: don't install CVS directories
7344 * device/lib/Makefile.in: added removal of CVS directories after install
7345 * doc/Makefile: fixed install, added local_icons
7346 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7347 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7348 * src/ds390/gen.c (genRightShift): fixed bug #870788
7349 * src/SDCCast.c (decorateType): fixed bug #870781
7351 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7353 PIC16 port related changes:
7354 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7355 added variable stackPos,
7357 * gen.c: genCall, assignResultValue: added support for
7358 pushing/retrieving function parameters to/from stack,
7359 genFunction,genEndFunction: setup stack frame for the
7361 genAddrOf: will be changed according to bug 863624
7363 * added files genutils.c and genutils.h which contain gen*
7364 debugged and optimised functions extracted from gen.c
7366 * glue.c: added variable 'externs' which holds extern symbols,
7367 pic16emitRegularMap: is modified to properly handle relocatable
7368 symbols under the new scheme,
7369 pic16createInterruptVect: is modified
7370 pic16printPublics: is modified to emit 'global' assembler directives,
7371 added pic16_printExterns to print extern symbols,
7372 pic16glue: initializes stack/frame pointer in the beginning of
7373 the assembly output. Temporary hack, will be corrected later,
7374 because gplink yet does not support stack and SDCC does not
7375 yet support a type of crt0.o object to create the final binary.
7377 * Removed many lines that contain 8051 legacy code.
7378 * The code is finally placed under a 'code' directive.
7379 * Added port specific options.
7381 * _process_pragma: simplified since now we do not need *special*
7382 include file to define SFR registers. But a separate header
7383 will be needed. This will be developed later.
7384 * _pic16_parseOptions: added, parses port specific options:
7385 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7386 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7387 --preplace-udata-with=
7389 * _pic16_setDefaultOptions: modified to initialize section names,
7390 but hack is temporarly out of order since it needs improvement.
7391 * _pic16_genAssemblerPreamble: configuration words are emitted by
7392 their address instead of their name. This part is incomplete and
7393 supports only the 18Fxx2 devices. Other devices will emit an error
7394 during assembly since they do not contain the same set of config
7396 * _pic16_genIVT: is modified,
7398 * pcode.c: added definitions for some hardware registers that are needed
7400 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7401 All PCI entries are updated. Now LFSR is supported.
7402 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7403 * added pic16_newpCodeOpLit2 to support instructions with
7404 two literal arguments
7405 * pic16_pCode2str: corrected code that emits assembler instructions
7406 with two literal operands and those that have an access bit modifier
7407 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7408 this fixes a bug which caused some labels to be lost, when an
7409 assembler directive was added, i.e. banksel,
7410 * pic16_FixRegisterBanking: improved logic that causes the insertion
7412 * InlineFunction: functions that are called once, are not any more
7413 inlined. This can be a port option in the future,
7415 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7417 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7418 hold the corresponding uninitialized symbols,
7419 * pic16_allocProcessorRegister: registers have explicit marked the
7421 * pic16_allocInternalRegister: registers are explicit marked as
7423 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7424 processing list, so bit registers were lost,
7427 * ralloc.h: added field 'accessBank' and original symbol operand
7428 in register definition,
7429 * removed the field isMapped from register definition,
7431 ** Several functions have been removed from various sources:
7432 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7433 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7434 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7435 pic16_assignRelocatableRegisters
7437 ** others have been introduced:
7438 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7439 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7441 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7443 * support/scripts/inc2h.pl: changed definition of BIT_AT
7444 to emit 'sbit at' instead of 'bit at'. This was a request.
7446 PIC16 port related preliminary changes:
7447 * gen.c: prefixed function popRegFromString with
7448 pic16_ and all references to it corrected
7449 * pcode.c: all pic16_pc_* hardware registers prefixed
7450 with underscore (_),
7451 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7452 * ralloc.c: newReg(): when register is REG_SFR then
7453 set address to rIdx,
7454 pic16_allocProcessorRegister(): marks register wasUsed=0
7455 pic16_writeUsedRegs(): added a call to assign processor
7456 registers via pic16_assignFixedRegisters
7458 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7460 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7461 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7462 variables in unused register banks. Also the SSEG is placed
7463 wherever there is enough space for it, and IDATA can be anywhere
7464 in internal RAM. For now compile using -Wl-Y[stack_size].
7465 The mem file is different for this option as well, since it
7466 makes no sense of talking about DSEG lenght.
7468 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7470 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7471 in certain cases, e.g. when ROM assignment, patch provided
7472 from Albert den Haan.
7474 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>
7476 Many signedness and type propagation fixes:
7477 * src/SDCCicode.c: made geniCodeCast() static
7478 replaced SPEC_ by IS_ (cosmetic)
7479 (operandOperation): fixed div and mod operation
7480 (usualBinaryConversions): added support for promotion of char
7481 (geniCodeMultiply): replaced (unsigned long) by (TYPE_UDWORD)
7482 (geniCodeDivision): replaced (unsigned long) by (TYPE_UDWORD)

8478 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8479 copied from genNearPointerSet()
8480 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8481 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
8482 If they pop r0/r1 they must be called in the opposite order than aopOp().
8483 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
8484 (resp. --stack-auto), prepared for --xstack

8493 these ports have their own __sdcc_external_start()
8495 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8497 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8498 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8499 type for bits was changed. It resulted in bit variables becoming
8500 global, which is not permitted in PIC 14 assembly output.
8502 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8504 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8517 A few small changes that speed up the peephole optimizer.
8521 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8523 Try to make the peephole optimizer smarter by maintaining
8524 an association between the assembly source code and the
8525 iCodes that originated them. Put this information to use
8526 with a new peephole rule condition "notVolatile" so that
8527 the rules can be aggressive yet still safe.
8532 * src/mcs51/peeph.def
8534 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8538 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8539 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8540 if the left or right operand symbols have the accuse flag set.
8542 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8544 Changed the type of the result of the ! (NOT) operator to char;
8545 previously it returned the same type as the source. This allows
8546 us to eliminate all the genFloatNot functions (all of its target
8547 implementations were very buggy) since !float can use the same
8550 * src/SDCCicode.c (ast2iCode): ! returns char

8552 * src/ds390/gen.c (genNot, genNotFloat),
8553 * src/z80/gen.c (genNot, genNotFloat),
8554 * src/pic/gen.c (genNot, genNotFloat),
8555 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

8559 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8560 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8561 during interrupts. Ensure WSAVE is located at a shared bank address.
8562 2. Fixed page selection in some places
8563 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8564 the registers name strings.
8565 4. Fixed "signed / unsigned compare" compiler warnings.
8566 5. The PIC port manages its own allocation of the general purpose
8567 registers, but makes no attempt to reuse them. As a result when
8568 compiling it soon runs out of general purpose registers. Some
8569 additional code was added to the files pcode.c and device.c to walk
8570 through the function call tree and rename the registers so that they
8580 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

8587 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8589 Made bitfield a distinct type from bit so that bitfields
8590 convert as per ANSI C and bits retain their traditional
8591 boolean style behaviour. Implemented bitfield support in
8599 * src/ds390/gen.c: bit v bitfield split
8600 * src/z80/gen.c: New support for bitfields
8601 * support/regression/tests/bitfields.c: reenabled z80,
8604 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8606 Rules 246.x, 247.x relate to bitfields, the others speed up
8607 access to xdata mapped I/O devices.
8609 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8611 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8613 Cleaned up genPackBits and genUnpackBits and added two helper
8614 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8615 for literal assignments in genPackBits (thanks to Frieder for
8621 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8623 Fixed bug #748310 (pointer to function type mishandled when the
8624 function name is omitted). Also fixed a SIGSEGV when a function
8625 attribute (reentrant, etc) is used on a non-function or on a
8626 function but misplaced before the parameter list.
8628 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8630 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

8653 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8655 Made the constant following the "interrupt" keyword optional. If
8656 omitted, the function will not automatically be given an entry
8657 in the interrupt vector table (similar to #pragma NOIV, but
8658 less syntacticly kludgy). The interrupt number is also now
8659 range checked. Also fixed a bug in the high order bit example

8675 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8677 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8678 be re-activated by defining REDUCE_LITERALS)
8679 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8680 unsigned, but are signed by default
8681 * src/SDCCval.c (constVal): rearranged
8682 * src/SDCCval.c (valMod): preliminary fix
8683 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9135 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
9136 the regression tests I'm not brave enough to enable 245.b, 245.c
9137 * doc/sdccman.lyx: added latex preamble for hyperref package.
9138 Using pdflatex this will give you a hyperlinked pdf file with
9139 bookmarks. (prepend '%' before /usepackage if this breaks something)

9177 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
9179 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
9180 it can be defined with CFLAGS when running configure
9181 * src/SDCCmain.c: fixed compiling + linking with object files
9183 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

9186 added --disable-pic16-port
9187 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9188 * src/SDCCmain.c: linkOptions is changed to set *,
9189 added if/endif conditional macros to remove options help
9190 messages from optionsTable when a port is not configured, added
9191 support for the PIc16 port in the ports table, when executing
9192 the compiler with no port specified on command line, a default
9193 port is selected with the new macro DEFAULT_PORT which is
9194 defined in port.h, in setDefaultOptions() linkOptions is removed
9195 from initialization assignment, since now it is a set,
9196 parseCmdLine uses setParseWithComma for linkOptions, in
9197 linkEdit() linkOptions are accessed with new function indexSet()
9198 which returns the i'th item of a set variable. See SDCCset.c, in
9199 linkEdit() when calling buildCmdLine(), added linkOptions as
9200 last argument. Now users can pass arguments to gplink via the
9201 -Wl option, main() uses pic16glue() to glue up pic16 programs
9202 * src/SDCCpeeph.c: various changes to support pic16

9213 * src/pic16/glue.c: commented out some error producing lines
9214 * src/pic16/main.c: __config directives are commented out to stop
9215 gpasm complaining and test the linkage with gplink, _linkCmd and
9216 _asmCmd changed to be more gplink and gpasm friendly
9217 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9218 produced an error when parsed, peep rule 12 is added to utilize
9219 movff, but it is commented out since the pCode does not support
9220 yet a command with 2 address arguments
9222 2003-05-18 <johan AT balder>
9224 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
9225 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9249 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
9251 2003-05-11 Borut Razem <borut.razem AT siol.net>
9253 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9254 the path of bin directory, so that PATH is the only env. variable, which has to be set
9255 in case of standard installation.
9256 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

10285 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10287 * in \sdcc\as\mcs51\ changed these files in order to create an
10288 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10289 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10290 following files to include the previous two files: aslink.dsp,
10291 Makefile.aslink, Makefile.bcc, and Makefile.in.
10293 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10294 .adb instead of .cdb
10296 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10298 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10299 value from option --iram-size.
10301 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10303 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10306 2002-09-18 <wiml AT hhhh.org>
10308 * SDCClrange.h: exposed setFromRange() and setToRange()
10309 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10310 packRegsForAccUse() (bug 542397)
10311 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10312 multiple times and emitting the fetch operations more than once
10313 added aopGetUsesAcc() function to allow binary operators to
10314 fetch their operands in the correct order; made genMinus() emit
10315 compact code for X = LITERAL - Y
10317 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10318 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10319 sprintf() in line 1267.
10321 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10322 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10325 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10326 Changes to aslink (All the changes are marked with 'JCF'):
10328 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10331 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10332 area BSEG. Also moves, if possible, the DATA area down into the internal
10333 ram so more space is available.
10335 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10338 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10339 not bytes. Function summary() which creates a memory usage summary
10340 file with extension .mem. Reports of overlaping stack and small stack
10341 size. If the space for the stack is less than 16 bytes aslink trows a
10344 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10345 the 8051. Option 'y' for memory summary output file.
10347 Changes to sdcc (All the changes are marked with 'JCF'):
10349 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10351 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10352 overlaying area for it (uses RegBankUsed[4]).
10354 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10355 bank zero as used by default. By default aslink locates the stack
10356 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10357 the creation of the .mem file. Delegates the allocation of data area
10358 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10359 the begining of the stack area to aslink.
10361 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10362 glue() in SDCCglue.c creates an area for it.
10364 2002-09-03 Borut Razem <borut.razem AT siol.net>
10365 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10366 sdcc/src/pic/glue.c:
10367 introduced atexit() handler for teporay files removal in case of
10368 errors, assertions, ...
10370 2002-08-29 Borut Razem <borut.razem AT siol.net>
10371 * sdcc/support/cpp2/auto-host_vc_in.h:
10372 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10373 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10374 Maybe there is a similar problem with BORLANDC? It should be checked!
10376 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10377 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10378 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10379 was not executed, and the compiler (cl) launched a warning:
10380 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10382 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>

10385 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10386 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10388 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10389 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10390 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10391 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10392 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10393 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10394 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10395 - added Release configuration in VS projects
10396 - review of compiler an linker options
10397 - VC .exe files are generated in bin_vc directory, not to interfere
10398 with binaries generated from other projects (cygwin, mingw, bcc ...)
10400 * sdcc/src/yacc.dsp: added
10402 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10403 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10404 and insert the version number definitions from .version
10406 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10408 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10409 added - genarate auto-host.h using auto-host_vc_in.h as template
10412 removed from CVS, generated automatically
10414 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10415 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10417 2002-08-11 Borut Razem <borut.razem AT siol.net>
10418 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10420 2002-08-10 Borut Razem <borut.razem AT siol.net>
10421 * src/SDCCmain.c (main):
10422 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10423 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10424 The consequence was that some temporary files were not removed.
10427 unification of code in functions tempfilename() and tempfile():
10428 function tempnam() is defined in Visual Studio 6.0 and .NET
10430 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10432 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10433 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10434 - removed compiler command line option /WX: Treats all warnings as errors
10435 - update a list of source files, included into the project
10437 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10438 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10439 changed project type to Generic Project so that can be correcly converted to VS.NET project
10441 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10443 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10445 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10447 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10448 added return 0 statements after assert() to make compiler happy
10450 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10451 added newline in the def file to keep MSC compiler satisfied
10453 * sdcc/src/z80/gen.c:
10454 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10455 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10456 - solved MSC error in function aopDump()
10458 * sdcc_vc.h: define PREFIX as "\\sdcc"
10460 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

10633 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10635 * sdcc/src/SDCCloop.c:
10636 Previous fix was not good. basic blocks that have "break" or "return" are
10637 not really partof a loop , but live ranges used in these blocks should
