364 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
366 Enabled VPATH feature: changed nearly all Makefiles (149 files).
367 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
369 One basic decision: e.g. src/clean.mk includes further files. In order
370 to make this work there are two solutions:
371 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
372 run configure on them. This way they can use
373 'include $(srcdir)/port-clean.mk'
374 - always include clean.mk by the Makefile at the same level. To avoid
375 that `make clean` tries to include and build Makefile.dep the
376 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
377 implemented, because now even `make uninstall` doesn't create
378 Makefile.in. clean.mk could be eliminated by pasting it in
381 * debugger/mcs51/Makefile.in: build own objects from library sources
382 (SLIB, SDCC) in current directory
384 * configure, configure.in: renamed --disable-device-lib-build in
385 --disable-device-lib; added --enable-doc, the required tools are
386 searched by configure; added result message; the toolchain for the
387 belonging ports are now only built, if the port is enabled.
389 * support/regression/*: all output is written in directory gen, because
390 the fwk and ports directories don't livet in the build tree using vpath
392 * doc/sdccman.lyx: renamed --disable-device-lib-build to
393 --disable-device-lib, added --enable-doc, added section VPATH
395 * sim/ucsim/configure.in,
396 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
397 z80 are enabled by default
399 2006-04-24 Raphael Neider <rneider AT web.de>
401 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
402 to config word, "pic14_"-prefixed some extern functions
403 (pic14_emitConfigWord): emit __config directive(s) if assignment to
404 config word has been found
405 * src/pic/device.h: added prototypes
406 * src/pic/pcode.c: added "pic14_"-prefix where needed

409 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
411 (pic14emitRegularMap): ignore config words,
412 (pic14createInterruptVect): moved generating __config directives away

428 * device/examples/main8051.c: deleted - it was removed from CVS

431 * src/SDCCalloc.h: deleted - it was removed from CVS

687 the left operand is shorter than the result (c* = lit-c* + int),
689 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
692 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
694 * src/.version: increased version number to 2.5.5
695 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
696 linking is done manually in pic16 port's _linkEdit,
697 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
698 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,

700 allocate asmop as AOP_ACC,
701 (aopForRemat): added parameter 'bool result' in function declaration,

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

784 port->fun_prefix anymore (may change later),
785 (genFunction, genEndFunction): do not store/restore local registers for
786 _main (this should take care the --main-return command line option in
788 (genOr): removed some legacy pic-port instructions,
789 * src/pic16/genarith.c (genAddLit): re-enabled old code because
790 performing operations with SFR's causes data to be written more than
791 once to each SFR. Perhaps SFRs should be handled in special cases...
792 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
794 * src/pic16/main.c (_process_pragma): stack bound checking did not take
795 into account for stack starting position,
796 (struct OPTIONS pic16_optionsTable): added command line argument
797 --extended or -y for Extended Instruction Support,
798 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
799 (deassignLRs): *** perhaps the most important change, old 'for' code
800 (commented out for reference), didn't account for some registers which
801 were left marked 'not free' after a pointer operation. The change
802 reduces register usage a lot in some cases

3069 on rIfx (genCmp was broken)
3071 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3073 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
3074 * src/z80/main.c (_keywords[]),
3075 * src/SDCCglobal.h (struct options),
3077 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3078 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3079 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3080 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3081 always available in leading double underscore form. The C99 support is
3082 mostly missing, but it's a start.
3083 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3084 reserved identifier "__data".
3086 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
3088 * src/mcs51/peeph.def: fixed bug 1170013

3130 immedDom() returning wrong block; probably fixes bug #1160833)
3132 2005-03-20 Borut Razem <borut.razem AT siol.net>
3134 * support/scripts/inc2h.pl: WIN32 port

3162 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3164 * device/lib/printf_large.c: removed inline assembly for portability and
3165 readability. Use printf_fast if speed or size are more important.
3166 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3167 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3169 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3171 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3172 prevent compiler warning
3174 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3176 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3177 moved to level 0 and declared as static. Also they are explicit
3178 placed in access bank. This was necessery because some times they
3179 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3180 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3181 optimizations. Currently only compare to unsigned char is implemented,
3182 * src/pic16/gen.c: added fReturnIdx array,
3183 * (struct resolvedIfx) is moved to gen.h and made public,
3184 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3185 * (aopForSym): added an optimization to directly store in stack of
3186 the operand of a SEND iCode,
3187 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3188 but as registers instead (AOP_REG) using the fReturnIdx array,
3189 * (pic16_freeAsmop): remove the freed register from the
3190 _G.sregsAlloc field,
3191 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3192 a compare of 'WREG',
3193 * (pic16_popGetTempRegCond): changed function prototype, now
3194 function takes also a bitVector argument v which holds the current
3195 set of registers that are allocated for stack access by aopForSym,
3196 registers allocated in aopForSym for accessing stack symbols are not
3197 any more part of the functions usedRegs field,
3198 * (genCall): some times aopOp is called for a stack variable to be
3199 send, aopForSym might perform the push, if this is true make sure
3200 that genCall doesn't push the variable twice by testing _G.resDirect,
3201 * (genFunction): changed testing for unspecified interrupt number
3202 from 256 to INTNO_UNSPEC,
3203 * modified selection scheme of frame pointer generation. Previously
3204 if function did use local registers a frame pointer was generated,
3205 now a frame pointer is generated only if function has arguments
3206 (that need PLUSW2 register access), or has stack arguments, or the
3207 compiler is not instructed to omit the frame pointer,
3208 * (genEndFunction): before restoring local registers that were saved
3209 in the function preamble, also restore the registers that *might*
3210 have been allocated for stack access,
3211 * (genRet): removed some old comments,
3212 * (genCmp, the active (RN's) version): added a call to the
3213 pic16_genCmp_special function to perform the compare with a more
3214 robust and optimized way,
3215 * (genInline): a feature has been added in inline code generation,
3216 which allows a wildcard variable substitution when writing inline
3217 assembly. Code is incomplete and experimental therefore undocumented,
3218 * (genCast): changed order of aopOp for result and right to allow
3219 aopForSym to directly load the result if possible,
3220 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3221 perform an optimized compare on some selected special occasions,
3222 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3223 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3224 generate an IVT any more,
3225 * src/pic16/main.c (pic16_optionsTable): added command line option
3227 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3228 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3230 * src/pic16/NOTES: Raphael Neider added in list of active developers
3231 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3232 jumptable_end to prevent bug #,
3233 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3234 inCond and outCond fields,
3235 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3236 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3237 turn off register spilling,
3238 * (packRegsForOneUse): synced with other ports' versions although it
3239 is not used currently,
3240 * (pic16_packRegisters): added an optimization while reading
3241 structure bitfields, some registers may be saved (malloc code is
3242 decreased by 80 bytes)
3244 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3246 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3247 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3248 this can be optimized more?
3250 2005-03-10 Raphael Neider <rneider AT web.de>
3252 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3253 genNearPointerGet): (hopefully) fixed access to bitfields via
3254 pointers (p->bitN = x; and x = p->bitN; failed)
3256 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
3258 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

3299 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
3300 to keep the correct label reference count when adding/removing references
3301 to labels. A peephole file using this is appended to patch #1144962.

3433 * src/pic16/main.c (_process_pragma): fixed another malloc bug
3434 (sizeof(sectNames) changed to sizeof(sectName))
3435 Both patches fix segfaults under MinGW.

3441 * src/pic16/gen.c (pic16_aopOp,pic16_popGet): added handling
3442 of (byte sized) temporaries (assign them to WREG for now)
3443 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
3444 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
3445 this might fix SIGSEGVs on MinGW...
3446 * src/SDCCopt.c (killDeadCode): restored original behaviour
3447 (volatile operands might get thrown away though)
3449 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
3451 * src/pic16/gen.c: fixed bug #1106975,

3905 2004-11-25 Vangelis Rokas <vrokas AT otenet.gr>
3907 * src/pic16/pcode.c: fixed bug which may produce error in non-GNU
3910 2004-11-25 Vangelis Rokas <vrokas AT otenet.gr>
3912 * src/pic16/device.h,
3913 * src/pic16/genarith.c,
3916 * src/pic16/pcode.c: applied patches #1068154 and #1070213
3918 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
3920 Large cummulative patch for pic16 port.
3921 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
3922 to call when a stack overflow occurs,
3923 * (malloc.h): added CVS Id tag,
3924 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3926 * added libc directory. The current version of LibC contains string
3927 functions, ctype functions and macros and some functions of the
3928 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3929 be extensively tested in the future. Standard disclaimer here.
3930 Library is not automatically build yet. But one can build it by
3931 invoking 'make' inside the libc directory.
3932 * added ADC library under libio. Preliminary version yet.
3934 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
3935 * src/pic16/gen.c (aopForRemat): asmop size is filled by
3936 aopForRemat() now and not by pic16_aopOp(),
3937 * (pic16_popGetTempReg): removed warning messgae when allocating
3938 temporary registers, its a buggy feature and will be removed,
3939 * (pic16_popGet): set register instance field in AOP_CRY,
3940 * (pic16_outBitC): fixed for results in size greater than 1,
3941 * (genUminusFloat): fixed for pic16, ported code from mcs51,
3942 * (pic16_storeForReturn): optimized return of 0,
3943 * (genCmp): experimental code for new genCmp which uses PIC18's
3944 special compare&skip instructions. Initial tests fail some times
3945 with variables grater than 1 byte in size, so new code is disabled,
3946 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3948 * (genCast): began a fix to optimize the casting of a bit to another
3949 bit, now assigning a bitfield to another bitfield will fail, sorry,
3950 * src/pic16/main.c: disabled the use of lr-support feature,
3951 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
3952 * added some function prototypes, added function _debugf prototype,
3953 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
3954 bits with offset (case PO_GPR_BIT),
3955 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
3957 * (isBankInstruction): modified to return 0 for no banking instruction,
3958 and 1 for banking instruction,
3959 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3960 caused stop processing pCodes after a inline assembly block,
3961 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
3962 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
3963 registers when it shouldn't,
3964 * src/pic16/ralloc.c (allocReg): add preliminary support for
3965 supporting a limited set of temporary registers,
3967 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3969 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
3970 genDataPointerSet): ensure assignments always copy in MSB to LSB
3972 (loadRegFromAop): recognize CLRH optimization,
3973 (genFunction): optimize RECEIVE iCodes in reentrant functions
3975 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3977 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
3978 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
3980 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

3986 * device/lib/_gptrget.c (_gptrget),
3987 * device/lib/_gptrgetc.c (_gptrgetc),
3988 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
3989 instead of sjmp to ret
3990 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
3991 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks

6975 loaded with the linker search paths (-L arguments) and the libraries
6976 to be linked with the current source (-l arguments). Changes
6977 currently will affect only the pic16 port.
6978 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6979 include path the port specific paths and port specific libraries,

7000 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7001 when generating output files to configure the pic16 library,
7002 but now I've commented it out, since gputils aren't installed in the
7003 SF compile farm, so library won't compile
7005 * device/lib/Makefile.in (version 1.56): initially I've added in
7006 target 'all' the prerequestive 'model-pic16' so it compiled the
7007 pic16 library, but now I've commented it out for the same reasons
7009 * added targets 'model-pic16' and 'objects-pic16' to compile the
7011 * added target 'port-specific-objects-pic16' to handle the
7012 generated libraries and copy them into the build/ directory
7013 * added target 'clean-intermediate-pic16' to clean intermediate
7014 files into pic16 directory
7015 * in target 'installdirs' added line to create directory pic16 in
7016 the installation path
7018 * device/include/Makefile.in (version 1.11): in target 'install'
7019 added lines to copy all header files to installation path,
7020 * in target 'installdirs' added line create directory for pic16
7021 headers in the installation path

7036 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7037 option so that it actually works. Made it specific to the z80, since
7038 the gbz80 doesn't have these kinds of I/O ports.
7040 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7042 * device/include/z180.h,

7050 * src/z80/main.c (_process_pragma): add support for pragmas bank and
7051 portmode; added deprecation warning for bank= and protmode= forms.
7052 Also, guard against buffer overflow.
7053 * src/z80/gen.c (aopGet): generate better code for sfr banked read
7055 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7057 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also

7064 Mainly changes to support compilation of the device libraries
7065 * src/pic16/device.c: stack is allocated via symbol and not
7066 via literal number. The symbol is placed in the corresponding
7067 position of the data ram
7068 * (pic16_dump_section): relocatable and absolute uninitialized
7069 data are now emitted in sorted order to reduce section naming,
7070 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7071 weren't marked as being in the access bank,
7073 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7075 Added portion of GNU PIC Library under the directory
7076 device/include/pic16 and device/lib/pic16. These files
7077 contain the declarations of SFRs for the PIC18Fxx2 devices.
7078 The directory is initialized via configure from toplevel.
7080 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
7082 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
7083 the spilllocations to be compared correctly

7108 all over. Telling LaTeX to be less strict with word spacing
7109 to better keep the right margin. Changed some notes about
7110 maintainance of the ports in section 3.2.1 - is it OK like this?
7112 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7149 UPPER for immediate operands,
7150 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7152 * src/pic16/peeph.def: all peepholes with movff are commented out,
7153 because there is a problem in the pcode peep optimizer,
7154 * src/pic16/ralloc.c: the register allocator can now reuse local

7156 * src/pic16/ralloc.h: added flag isLocal in structure regs,
7158 Added file src/pic16/NOTES with information about program writing on
7159 the current port version.

7264 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7266 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7267 (default behaviour).
7269 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7271 A python script to validate compiler diagnostic messages. It can be
7272 used to verify that sdcc complains about bad c source code and
7273 gives a good location of the error.
7274 * support/valdiag/Makefile,
7275 * support/valdiag/valdiag.py,
7276 * support/valdiag/tests/*
7278 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7291 * src/common.h: added ifndef/define/endif macros
7292 around the header file.
7293 Bug reported from Jesus Calvino-Fraga
7295 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7297 * sdcc.spec: updated
7298 * device/include/Makefile.in: don't install CVS directories
7299 * device/lib/Makefile.in: added removal of CVS directories after install
7300 * doc/Makefile: fixed install, added local_icons
7301 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7302 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7303 * src/ds390/gen.c (genRightShift): fixed bug #870788
7304 * src/SDCCast.c (decorateType): fixed bug #870781
7306 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7308 PIC16 port related changes:
7309 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7310 added variable stackPos,
7312 * gen.c: genCall, assignResultValue: added support for
7313 pushing/retrieving function parameters to/from stack,
7314 genFunction,genEndFunction: setup stack frame for the
7316 genAddrOf: will be changed according to bug 863624
7318 * added files genutils.c and genutils.h which contain gen*
7319 debugged and optimised functions extracted from gen.c
7321 * glue.c: added variable 'externs' which holds extern symbols,
7322 pic16emitRegularMap: is modified to properly handle relocatable
7323 symbols under the new scheme,
7324 pic16createInterruptVect: is modified
7325 pic16printPublics: is modified to emit 'global' assembler directives,
7326 added pic16_printExterns to print extern symbols,
7327 pic16glue: initializes stack/frame pointer in the beginning of
7328 the assembly output. Temporary hack, will be corrected later,
7329 because gplink yet does not support stack and SDCC does not
7330 yet support a type of crt0.o object to create the final binary.
7332 * Removed many lines that contain 8051 legacy code.
7333 * The code is finally placed under a 'code' directive.
7334 * Added port specific options.
7336 * _process_pragma: simplified since now we do not need *special*
7337 include file to define SFR registers. But a separate header
7338 will be needed. This will be developed later.
7339 * _pic16_parseOptions: added, parses port specific options:
7340 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7341 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7342 --preplace-udata-with=
7344 * _pic16_setDefaultOptions: modified to initialize section names,
7345 but hack is temporarly out of order since it needs improvement.
7346 * _pic16_genAssemblerPreamble: configuration words are emitted by
7347 their address instead of their name. This part is incomplete and
7348 supports only the 18Fxx2 devices. Other devices will emit an error
7349 during assembly since they do not contain the same set of config
7351 * _pic16_genIVT: is modified,
7353 * pcode.c: added definitions for some hardware registers that are needed
7355 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7356 All PCI entries are updated. Now LFSR is supported.
7357 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7358 * added pic16_newpCodeOpLit2 to support instructions with
7359 two literal arguments
7360 * pic16_pCode2str: corrected code that emits assembler instructions
7361 with two literal operands and those that have an access bit modifier
7362 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7363 this fixes a bug which caused some labels to be lost, when an
7364 assembler directive was added, i.e. banksel,
7365 * pic16_FixRegisterBanking: improved logic that causes the insertion
7367 * InlineFunction: functions that are called once, are not any more
7368 inlined. This can be a port option in the future,
7370 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7372 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7373 hold the corresponding uninitialized symbols,
7374 * pic16_allocProcessorRegister: registers have explicit marked the
7376 * pic16_allocInternalRegister: registers are explicit marked as
7378 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7379 processing list, so bit registers were lost,
7382 * ralloc.h: added field 'accessBank' and original symbol operand
7383 in register definition,
7384 * removed the field isMapped from register definition,
7386 ** Several functions have been removed from various sources:
7387 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7388 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7389 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7390 pic16_assignRelocatableRegisters
7392 ** others have been introduced:
7393 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7394 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7396 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7398 * support/scripts/inc2h.pl: changed definition of BIT_AT
7399 to emit 'sbit at' instead of 'bit at'. This was a request.
7401 PIC16 port related preliminary changes:
7402 * gen.c: prefixed function popRegFromString with
7403 pic16_ and all references to it corrected
7404 * pcode.c: all pic16_pc_* hardware registers prefixed
7405 with underscore (_),
7406 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7407 * ralloc.c: newReg(): when register is REG_SFR then
7408 set address to rIdx,
7409 pic16_allocProcessorRegister(): marks register wasUsed=0
7410 pic16_writeUsedRegs(): added a call to assign processor
7411 registers via pic16_assignFixedRegisters
7413 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7415 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7416 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7417 variables in unused register banks. Also the SSEG is placed
7418 wherever there is enough space for it, and IDATA can be anywhere
7419 in internal RAM. For now compile using -Wl-Y[stack_size].
7420 The mem file is different for this option as well, since it
7421 makes no sense of talking about DSEG lenght.
7423 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7425 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7426 in certain cases, e.g. when ROM assignment, patch provided
7427 from Albert den Haan.
7429 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7982 not occur if the control variable is involved with a
7983 relational operator.

8472 A few small changes that speed up the peephole optimizer.
8476 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8478 Try to make the peephole optimizer smarter by maintaining
8479 an association between the assembly source code and the
8480 iCodes that originated them. Put this information to use
8481 with a new peephole rule condition "notVolatile" so that
8482 the rules can be aggressive yet still safe.

8495 if the left or right operand symbols have the accuse flag set.
8497 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8499 Changed the type of the result of the ! (NOT) operator to char;
8500 previously it returned the same type as the source. This allows
8501 us to eliminate all the genFloatNot functions (all of its target
8502 implementations were very buggy) since !float can use the same
8505 * src/SDCCicode.c (ast2iCode): ! returns char

8514 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8515 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8516 during interrupts. Ensure WSAVE is located at a shared bank address.
8517 2. Fixed page selection in some places
8518 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8519 the registers name strings.
8520 4. Fixed "signed / unsigned compare" compiler warnings.
8521 5. The PIC port manages its own allocation of the general purpose
8522 registers, but makes no attempt to reuse them. As a result when
8523 compiling it soon runs out of general purpose registers. Some
8524 additional code was added to the files pcode.c and device.c to walk
8525 through the function call tree and rename the registers so that they
8535 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

8542 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8544 Made bitfield a distinct type from bit so that bitfields
8545 convert as per ANSI C and bits retain their traditional
8546 boolean style behaviour. Implemented bitfield support in
8554 * src/ds390/gen.c: bit v bitfield split
8555 * src/z80/gen.c: New support for bitfields
8556 * support/regression/tests/bitfields.c: reenabled z80,
8559 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8561 Rules 246.x, 247.x relate to bitfields, the others speed up
8562 access to xdata mapped I/O devices.
8564 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8566 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8568 Cleaned up genPackBits and genUnpackBits and added two helper
8569 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8570 for literal assignments in genPackBits (thanks to Frieder for
8576 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8578 Fixed bug #748310 (pointer to function type mishandled when the
8579 function name is omitted). Also fixed a SIGSEGV when a function
8580 attribute (reentrant, etc) is used on a non-function or on a
8581 function but misplaced before the parameter list.

8608 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8610 Made the constant following the "interrupt" keyword optional. If
8611 omitted, the function will not automatically be given an entry
8612 in the interrupt vector table (similar to #pragma NOIV, but
8613 less syntacticly kludgy). The interrupt number is also now
8614 range checked. Also fixed a bug in the high order bit example

9090 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
9091 the regression tests I'm not brave enough to enable 245.b, 245.c
9092 * doc/sdccman.lyx: added latex preamble for hyperref package.
9093 Using pdflatex this will give you a hyperlinked pdf file with
9094 bookmarks. (prepend '%' before /usepackage if this breaks something)

9135 it can be defined with CFLAGS when running configure
9136 * src/SDCCmain.c: fixed compiling + linking with object files
9138 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

9141 added --disable-pic16-port
9142 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9143 * src/SDCCmain.c: linkOptions is changed to set *,
9144 added if/endif conditional macros to remove options help
9145 messages from optionsTable when a port is not configured, added
9146 support for the PIc16 port in the ports table, when executing
9147 the compiler with no port specified on command line, a default
9148 port is selected with the new macro DEFAULT_PORT which is
9149 defined in port.h, in setDefaultOptions() linkOptions is removed
9150 from initialization assignment, since now it is a set,
9151 parseCmdLine uses setParseWithComma for linkOptions, in
9152 linkEdit() linkOptions are accessed with new function indexSet()
9153 which returns the i'th item of a set variable. See SDCCset.c, in
9154 linkEdit() when calling buildCmdLine(), added linkOptions as
9155 last argument. Now users can pass arguments to gplink via the
9156 -Wl option, main() uses pic16glue() to glue up pic16 programs

9168 * src/pic16/glue.c: commented out some error producing lines
9169 * src/pic16/main.c: __config directives are commented out to stop
9170 gpasm complaining and test the linkage with gplink, _linkCmd and
9171 _asmCmd changed to be more gplink and gpasm friendly
9172 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9173 produced an error when parsed, peep rule 12 is added to utilize
9174 movff, but it is commented out since the pCode does not support
9175 yet a command with 2 address arguments
9177 2003-05-18 <johan AT balder>
9179 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9204 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
9206 2003-05-11 Borut Razem <borut.razem AT siol.net>
9208 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9209 the path of bin directory, so that PATH is the only env. variable, which has to be set
9210 in case of standard installation.
9211 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

10238 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10240 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10242 * in \sdcc\as\mcs51\ changed these files in order to create an
10243 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10244 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10245 following files to include the previous two files: aslink.dsp,
10246 Makefile.aslink, Makefile.bcc, and Makefile.in.
10248 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10249 .adb instead of .cdb
10251 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10253 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10254 value from option --iram-size.
10256 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10258 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10261 2002-09-18 <wiml AT hhhh.org>
10263 * SDCClrange.h: exposed setFromRange() and setToRange()
10264 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10265 packRegsForAccUse() (bug 542397)
10266 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10267 multiple times and emitting the fetch operations more than once
10268 added aopGetUsesAcc() function to allow binary operators to
10269 fetch their operands in the correct order; made genMinus() emit
10270 compact code for X = LITERAL - Y
10272 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10273 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10274 sprintf() in line 1267.
10276 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10277 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10280 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10281 Changes to aslink (All the changes are marked with 'JCF'):
10283 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10286 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10287 area BSEG. Also moves, if possible, the DATA area down into the internal
10288 ram so more space is available.
10290 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10293 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10294 not bytes. Function summary() which creates a memory usage summary
10295 file with extension .mem. Reports of overlaping stack and small stack
10296 size. If the space for the stack is less than 16 bytes aslink trows a
10299 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10300 the 8051. Option 'y' for memory summary output file.
10302 Changes to sdcc (All the changes are marked with 'JCF'):
10304 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10306 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10307 overlaying area for it (uses RegBankUsed[4]).
10309 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10310 bank zero as used by default. By default aslink locates the stack
10311 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10312 the creation of the .mem file. Delegates the allocation of data area
10313 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10314 the begining of the stack area to aslink.
10316 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10317 glue() in SDCCglue.c creates an area for it.
10319 2002-09-03 Borut Razem <borut.razem AT siol.net>
10320 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10321 sdcc/src/pic/glue.c:
10322 introduced atexit() handler for teporay files removal in case of
10323 errors, assertions, ...
10325 2002-08-29 Borut Razem <borut.razem AT siol.net>
10326 * sdcc/support/cpp2/auto-host_vc_in.h:
10327 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10328 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10329 Maybe there is a similar problem with BORLANDC? It should be checked!
10331 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10332 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10333 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10334 was not executed, and the compiler (cl) launched a warning:
10335 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10337 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10338 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10340 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10341 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects

10346 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10347 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10348 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10349 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10350 - added Release configuration in VS projects
10351 - review of compiler an linker options
10352 - VC .exe files are generated in bin_vc directory, not to interfere
10353 with binaries generated from other projects (cygwin, mingw, bcc ...)
10355 * sdcc/src/yacc.dsp: added
10357 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10358 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10359 and insert the version number definitions from .version
10361 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10363 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10364 added - genarate auto-host.h using auto-host_vc_in.h as template
10367 removed from CVS, generated automatically
10369 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10370 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10372 2002-08-11 Borut Razem <borut.razem AT siol.net>
10373 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10375 2002-08-10 Borut Razem <borut.razem AT siol.net>
10376 * src/SDCCmain.c (main):
10377 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10378 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10379 The consequence was that some temporary files were not removed.
10382 unification of code in functions tempfilename() and tempfile():
10383 function tempnam() is defined in Visual Studio 6.0 and .NET
10385 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10387 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10388 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10389 - removed compiler command line option /WX: Treats all warnings as errors
10390 - update a list of source files, included into the project
10392 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,

10406 added newline in the def file to keep MSC compiler satisfied
10408 * sdcc/src/z80/gen.c:
10409 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10410 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10411 - solved MSC error in function aopDump()
10413 * sdcc_vc.h: define PREFIX as "\\sdcc"

10591 Previous fix was not good. basic blocks that have "break" or "return" are
10592 not really partof a loop , but live ranges used in these blocks should
