372 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
374 Enabled VPATH feature: changed nearly all Makefiles (149 files).
375 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
377 One basic decision: e.g. src/clean.mk includes further files. In order
378 to make this work there are two solutions:
379 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
380 run configure on them. This way they can use
381 'include $(srcdir)/port-clean.mk'
382 - always include clean.mk by the Makefile at the same level. To avoid
383 that `make clean` tries to include and build Makefile.dep the
384 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
385 implemented, because now even `make uninstall` doesn't create
386 Makefile.in. clean.mk could be eliminated by pasting it in
389 * debugger/mcs51/Makefile.in: build own objects from library sources
390 (SLIB, SDCC) in current directory
392 * configure, configure.in: renamed --disable-device-lib-build in
393 --disable-device-lib; added --enable-doc, the required tools are
394 searched by configure; added result message; the toolchain for the
395 belonging ports are now only built, if the port is enabled.
397 * support/regression/*: all output is written in directory gen, because
398 the fwk and ports directories don't livet in the build tree using vpath
400 * doc/sdccman.lyx: renamed --disable-device-lib-build to
401 --disable-device-lib, added --enable-doc, added section VPATH
403 * sim/ucsim/configure.in,
404 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
405 z80 are enabled by default
407 2006-04-24 Raphael Neider <rneider AT web.de>
409 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
410 to config word, "pic14_"-prefixed some extern functions
411 (pic14_emitConfigWord): emit __config directive(s) if assignment to
412 config word has been found
413 * src/pic/device.h: added prototypes
414 * src/pic/pcode.c: added "pic14_"-prefix where needed

420 (pic14createInterruptVect): moved generating __config directives away

431 fixes #1469504 and #1474602,
432 (pCodeRegOptimizeRegUsage): fixed typo in comment
434 2006-04-24 Borut Razem <borut.razem AT siol.net>
436 * device/examples/main8051.c: deleted - it was removed from CVS
437 24.mar.2000 and after that modified 18.feb.2001, so it reappered

439 * src/SDCCalloc.h: deleted - it was removed from CVS
440 3.feb.2001 and after that modified 18.feb.2001, so it reappered

692 2006-03-16 Raphael Neider <rneider AT web.de>
694 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
695 the left operand is shorter than the result (c* = lit-c* + int),
697 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
700 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
702 * src/.version: increased version number to 2.5.5
703 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
704 linking is done manually in pic16 port's _linkEdit,
705 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
706 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,

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

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

786 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
787 which dumps before the function entry point a data byte which represents
788 the number of the local variables used by the specified function, added
789 'xinst' for initial support for Extended Instruction Support,
790 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
791 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
792 port->fun_prefix anymore (may change later),
793 (genFunction, genEndFunction): do not store/restore local registers for
794 _main (this should take care the --main-return command line option in
796 (genOr): removed some legacy pic-port instructions,
797 * src/pic16/genarith.c (genAddLit): re-enabled old code because
798 performing operations with SFR's causes data to be written more than
799 once to each SFR. Perhaps SFRs should be handled in special cases...
800 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
802 * src/pic16/main.c (_process_pragma): stack bound checking did not take
803 into account for stack starting position,
804 (struct OPTIONS pic16_optionsTable): added command line argument
805 --extended or -y for Extended Instruction Support,
806 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
807 (deassignLRs): *** perhaps the most important change, old 'for' code
808 (commented out for reference), didn't account for some registers which
809 were left marked 'not free' after a pointer operation. The change
810 reduces register usage a lot in some cases

3079 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3081 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
3082 * src/z80/main.c (_keywords[]),
3083 * src/SDCCglobal.h (struct options),
3085 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3086 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3087 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3088 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3089 always available in leading double underscore form. The C99 support is
3090 mostly missing, but it's a start.
3091 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3092 reserved identifier "__data".
3094 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
3096 * src/mcs51/peeph.def: fixed bug 1170013

3140 2005-03-20 Borut Razem <borut.razem AT siol.net>
3142 * support/scripts/inc2h.pl: WIN32 port

3146 * device/lib/makefile.in: added abs.c and labs.c
3148 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
3150 * device/include/stdint.h: added
3151 * device/lib/abs.c: added

3170 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3172 * device/lib/printf_large.c: removed inline assembly for portability and
3173 readability. Use printf_fast if speed or size are more important.
3174 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3175 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3177 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3179 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3180 prevent compiler warning
3182 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3184 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3185 moved to level 0 and declared as static. Also they are explicit
3186 placed in access bank. This was necessery because some times they
3187 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3188 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3189 optimizations. Currently only compare to unsigned char is implemented,
3190 * src/pic16/gen.c: added fReturnIdx array,
3191 * (struct resolvedIfx) is moved to gen.h and made public,
3192 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3193 * (aopForSym): added an optimization to directly store in stack of
3194 the operand of a SEND iCode,
3195 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3196 but as registers instead (AOP_REG) using the fReturnIdx array,
3197 * (pic16_freeAsmop): remove the freed register from the
3198 _G.sregsAlloc field,
3199 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3200 a compare of 'WREG',
3201 * (pic16_popGetTempRegCond): changed function prototype, now
3202 function takes also a bitVector argument v which holds the current
3203 set of registers that are allocated for stack access by aopForSym,
3204 registers allocated in aopForSym for accessing stack symbols are not
3205 any more part of the functions usedRegs field,
3206 * (genCall): some times aopOp is called for a stack variable to be
3207 send, aopForSym might perform the push, if this is true make sure
3208 that genCall doesn't push the variable twice by testing _G.resDirect,
3209 * (genFunction): changed testing for unspecified interrupt number
3210 from 256 to INTNO_UNSPEC,
3211 * modified selection scheme of frame pointer generation. Previously
3212 if function did use local registers a frame pointer was generated,
3213 now a frame pointer is generated only if function has arguments
3214 (that need PLUSW2 register access), or has stack arguments, or the
3215 compiler is not instructed to omit the frame pointer,
3216 * (genEndFunction): before restoring local registers that were saved
3217 in the function preamble, also restore the registers that *might*
3218 have been allocated for stack access,
3219 * (genRet): removed some old comments,
3220 * (genCmp, the active (RN's) version): added a call to the
3221 pic16_genCmp_special function to perform the compare with a more
3222 robust and optimized way,
3223 * (genInline): a feature has been added in inline code generation,
3224 which allows a wildcard variable substitution when writing inline
3225 assembly. Code is incomplete and experimental therefore undocumented,
3226 * (genCast): changed order of aopOp for result and right to allow
3227 aopForSym to directly load the result if possible,
3228 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3229 perform an optimized compare on some selected special occasions,
3230 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3231 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3232 generate an IVT any more,
3233 * src/pic16/main.c (pic16_optionsTable): added command line option
3235 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3236 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3238 * src/pic16/NOTES: Raphael Neider added in list of active developers
3239 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3240 jumptable_end to prevent bug #,
3241 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3242 inCond and outCond fields,
3243 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3244 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3245 turn off register spilling,
3246 * (packRegsForOneUse): synced with other ports' versions although it
3247 is not used currently,
3248 * (pic16_packRegisters): added an optimization while reading
3249 structure bitfields, some registers may be saved (malloc code is
3250 decreased by 80 bytes)
3252 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3254 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3255 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3256 this can be optimized more?
3258 2005-03-10 Raphael Neider <rneider AT web.de>
3260 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3261 genNearPointerGet): (hopefully) fixed access to bitfields via
3262 pointers (p->bitN = x; and x = p->bitN; failed)
3264 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3307 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
3308 to keep the correct label reference count when adding/removing references
3309 to labels. A peephole file using this is appended to patch #1144962.
3311 2005-02-14 Raphael Neider <rneider AT web.de>

3441 * src/pic16/main.c (_process_pragma): fixed another malloc bug
3442 (sizeof(sectNames) changed to sizeof(sectName))
3443 Both patches fix segfaults under MinGW.
3445 2005-01-23 Raphael Neider <rneider AT web.de>

3448 Safe_[mc]?alloc()'ed variables
3449 * src/pic16/gen.c (pic16_aopOp,pic16_popGet): added handling
3450 of (byte sized) temporaries (assign them to WREG for now)
3451 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
3452 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
3453 this might fix SIGSEGVs on MinGW...
3454 * src/SDCCopt.c (killDeadCode): restored original behaviour
3455 (volatile operands might get thrown away though)
3457 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
3459 * src/pic16/gen.c: fixed bug #1106975,

3918 2004-11-25 Vangelis Rokas <vrokas AT otenet.gr>
3920 * src/pic16/device.h,
3921 * src/pic16/genarith.c,
3924 * src/pic16/pcode.c: applied patches #1068154 and #1070213
3926 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
3928 Large cummulative patch for pic16 port.
3929 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
3930 to call when a stack overflow occurs,
3931 * (malloc.h): added CVS Id tag,
3932 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3934 * added libc directory. The current version of LibC contains string
3935 functions, ctype functions and macros and some functions of the
3936 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3937 be extensively tested in the future. Standard disclaimer here.
3938 Library is not automatically build yet. But one can build it by
3939 invoking 'make' inside the libc directory.
3940 * added ADC library under libio. Preliminary version yet.
3942 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
3943 * src/pic16/gen.c (aopForRemat): asmop size is filled by
3944 aopForRemat() now and not by pic16_aopOp(),
3945 * (pic16_popGetTempReg): removed warning messgae when allocating
3946 temporary registers, its a buggy feature and will be removed,
3947 * (pic16_popGet): set register instance field in AOP_CRY,
3948 * (pic16_outBitC): fixed for results in size greater than 1,
3949 * (genUminusFloat): fixed for pic16, ported code from mcs51,
3950 * (pic16_storeForReturn): optimized return of 0,
3951 * (genCmp): experimental code for new genCmp which uses PIC18's
3952 special compare&skip instructions. Initial tests fail some times
3953 with variables grater than 1 byte in size, so new code is disabled,
3954 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3956 * (genCast): began a fix to optimize the casting of a bit to another
3957 bit, now assigning a bitfield to another bitfield will fail, sorry,
3958 * src/pic16/main.c: disabled the use of lr-support feature,
3959 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
3960 * added some function prototypes, added function _debugf prototype,
3961 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
3962 bits with offset (case PO_GPR_BIT),
3963 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
3965 * (isBankInstruction): modified to return 0 for no banking instruction,
3966 and 1 for banking instruction,
3967 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3968 caused stop processing pCodes after a inline assembly block,
3969 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
3970 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
3971 registers when it shouldn't,
3972 * src/pic16/ralloc.c (allocReg): add preliminary support for
3973 supporting a limited set of temporary registers,
3975 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3977 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
3978 genDataPointerSet): ensure assignments always copy in MSB to LSB
3980 (loadRegFromAop): recognize CLRH optimization,
3981 (genFunction): optimize RECEIVE iCodes in reentrant functions
3983 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3985 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
3986 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
3988 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

3999 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
4001 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

6983 loaded with the linker search paths (-L arguments) and the libraries
6984 to be linked with the current source (-l arguments). Changes
6985 currently will affect only the pic16 port.
6986 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6987 include path the port specific paths and port specific libraries,
6988 * gplink command now contains the $3 argument,

7004 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
7006 Documenting changes from previous commits.
7007 * configure.in (version 1.56),
7008 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7009 when generating output files to configure the pic16 library,
7010 but now I've commented it out, since gputils aren't installed in the
7011 SF compile farm, so library won't compile
7013 * device/lib/Makefile.in (version 1.56): initially I've added in
7014 target 'all' the prerequestive 'model-pic16' so it compiled the
7015 pic16 library, but now I've commented it out for the same reasons
7017 * added targets 'model-pic16' and 'objects-pic16' to compile the
7019 * added target 'port-specific-objects-pic16' to handle the
7020 generated libraries and copy them into the build/ directory
7021 * added target 'clean-intermediate-pic16' to clean intermediate
7022 files into pic16 directory
7023 * in target 'installdirs' added line to create directory pic16 in
7024 the installation path
7026 * device/include/Makefile.in (version 1.11): in target 'install'
7027 added lines to copy all header files to installation path,
7028 * in target 'installdirs' added line create directory for pic16
7029 headers in the installation path
7031 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

7044 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7045 option so that it actually works. Made it specific to the z80, since
7046 the gbz80 doesn't have these kinds of I/O ports.
7048 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7050 * device/include/z180.h,

7056 * device/lib/_strcmp.c,
7057 * device/lib/_strtok.c: fixed pragmas to non-deprecated form
7058 * src/z80/main.c (_process_pragma): add support for pragmas bank and
7059 portmode; added deprecation warning for bank= and protmode= forms.
7060 Also, guard against buffer overflow.
7061 * src/z80/gen.c (aopGet): generate better code for sfr banked read
7063 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7065 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
7066 changed interrupt vector table generation to only emit declared vectors.
7067 * device/include/Makefile.in: added missing backslash
7068 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)

7072 Mainly changes to support compilation of the device libraries
7073 * src/pic16/device.c: stack is allocated via symbol and not
7074 via literal number. The symbol is placed in the corresponding
7075 position of the data ram
7076 * (pic16_dump_section): relocatable and absolute uninitialized
7077 data are now emitted in sorted order to reduce section naming,
7078 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7079 weren't marked as being in the access bank,
7081 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7083 Added portion of GNU PIC Library under the directory
7084 device/include/pic16 and device/lib/pic16. These files
7085 contain the declarations of SFRs for the PIC18Fxx2 devices.
7086 The directory is initialized via configure from toplevel.
7088 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
7090 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
7091 the spilllocations to be compared correctly

7115 * doc/sdccman.lyx: Moved and added some sections, small changes
7116 all over. Telling LaTeX to be less strict with word spacing
7117 to better keep the right margin. Changed some notes about
7118 maintainance of the ports in section 3.2.1 - is it OK like this?
7120 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
7122 SDCC source changes:
7123 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

7157 UPPER for immediate operands,
7158 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7160 * src/pic16/peeph.def: all peepholes with movff are commented out,
7161 because there is a problem in the pcode peep optimizer,
7162 * src/pic16/ralloc.c: the register allocator can now reuse local
7163 function symbols for another function. This saves register usage.
7164 * src/pic16/ralloc.h: added flag isLocal in structure regs,
7166 Added file src/pic16/NOTES with information about program writing on
7167 the current port version.

7199 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7202 * src/z80/main.c: added missed needLinkerScript flags (more than
7203 one port structure defined in these file)
7204 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

7220 needLinkerScript flag
7222 * src/pic16/gen.c (genAddrOf): fixed bug #863624
7223 * src/pic/glue.c: added variable udata_section_name to
7224 override default uninitialized data segment definition for
7225 devices only with SHAREBANK memory (reported from Erik Epetrich)
7226 * (pic14emitOverlay): modified to emit a commented overlay segment
7227 directive when no overlay data exist
7228 * (picglue): modified to emit uninitialized data segment
7229 according to udata_section_name

7239 2004-01-07 Borut Razem <borut.razem AT siol.net>
7241 * support/scripts/sdcc.nsi: update PATH
7242 * support/scripts/sdcc.ico: craeted

7255 include information about variables allocated to the overlay
7258 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7260 * as/mcs51/lkmain.c: Help about -Y option

7272 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7274 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7275 (default behaviour).
7277 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7279 A python script to validate compiler diagnostic messages. It can be
7280 used to verify that sdcc complains about bad c source code and
7281 gives a good location of the error.
7282 * support/valdiag/Makefile,
7283 * support/valdiag/valdiag.py,
7284 * support/valdiag/tests/*
7286 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7299 * src/common.h: added ifndef/define/endif macros
7300 around the header file.
7301 Bug reported from Jesus Calvino-Fraga
7303 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7305 * sdcc.spec: updated
7306 * device/include/Makefile.in: don't install CVS directories
7307 * device/lib/Makefile.in: added removal of CVS directories after install
7308 * doc/Makefile: fixed install, added local_icons
7309 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7310 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7311 * src/ds390/gen.c (genRightShift): fixed bug #870788
7312 * src/SDCCast.c (decorateType): fixed bug #870781
7314 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7316 PIC16 port related changes:
7317 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7318 added variable stackPos,
7320 * gen.c: genCall, assignResultValue: added support for
7321 pushing/retrieving function parameters to/from stack,
7322 genFunction,genEndFunction: setup stack frame for the
7324 genAddrOf: will be changed according to bug 863624
7326 * added files genutils.c and genutils.h which contain gen*
7327 debugged and optimised functions extracted from gen.c
7329 * glue.c: added variable 'externs' which holds extern symbols,
7330 pic16emitRegularMap: is modified to properly handle relocatable
7331 symbols under the new scheme,
7332 pic16createInterruptVect: is modified
7333 pic16printPublics: is modified to emit 'global' assembler directives,
7334 added pic16_printExterns to print extern symbols,
7335 pic16glue: initializes stack/frame pointer in the beginning of
7336 the assembly output. Temporary hack, will be corrected later,
7337 because gplink yet does not support stack and SDCC does not
7338 yet support a type of crt0.o object to create the final binary.
7340 * Removed many lines that contain 8051 legacy code.
7341 * The code is finally placed under a 'code' directive.
7342 * Added port specific options.
7344 * _process_pragma: simplified since now we do not need *special*
7345 include file to define SFR registers. But a separate header
7346 will be needed. This will be developed later.
7347 * _pic16_parseOptions: added, parses port specific options:
7348 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7349 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7350 --preplace-udata-with=
7352 * _pic16_setDefaultOptions: modified to initialize section names,
7353 but hack is temporarly out of order since it needs improvement.
7354 * _pic16_genAssemblerPreamble: configuration words are emitted by
7355 their address instead of their name. This part is incomplete and
7356 supports only the 18Fxx2 devices. Other devices will emit an error
7357 during assembly since they do not contain the same set of config
7359 * _pic16_genIVT: is modified,
7361 * pcode.c: added definitions for some hardware registers that are needed
7363 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7364 All PCI entries are updated. Now LFSR is supported.
7365 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7366 * added pic16_newpCodeOpLit2 to support instructions with
7367 two literal arguments
7368 * pic16_pCode2str: corrected code that emits assembler instructions
7369 with two literal operands and those that have an access bit modifier
7370 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7371 this fixes a bug which caused some labels to be lost, when an
7372 assembler directive was added, i.e. banksel,
7373 * pic16_FixRegisterBanking: improved logic that causes the insertion
7375 * InlineFunction: functions that are called once, are not any more
7376 inlined. This can be a port option in the future,
7378 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7380 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7381 hold the corresponding uninitialized symbols,
7382 * pic16_allocProcessorRegister: registers have explicit marked the
7384 * pic16_allocInternalRegister: registers are explicit marked as
7386 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7387 processing list, so bit registers were lost,
7390 * ralloc.h: added field 'accessBank' and original symbol operand
7391 in register definition,
7392 * removed the field isMapped from register definition,
7394 ** Several functions have been removed from various sources:
7395 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7396 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7397 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7398 pic16_assignRelocatableRegisters
7400 ** others have been introduced:
7401 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7402 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7404 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7406 * support/scripts/inc2h.pl: changed definition of BIT_AT
7407 to emit 'sbit at' instead of 'bit at'. This was a request.
7409 PIC16 port related preliminary changes:
7410 * gen.c: prefixed function popRegFromString with
7411 pic16_ and all references to it corrected
7412 * pcode.c: all pic16_pc_* hardware registers prefixed
7413 with underscore (_),
7414 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7415 * ralloc.c: newReg(): when register is REG_SFR then
7416 set address to rIdx,
7417 pic16_allocProcessorRegister(): marks register wasUsed=0
7418 pic16_writeUsedRegs(): added a call to assign processor
7419 registers via pic16_assignFixedRegisters
7421 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7423 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7424 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7425 variables in unused register banks. Also the SSEG is placed
7426 wherever there is enough space for it, and IDATA can be anywhere
7427 in internal RAM. For now compile using -Wl-Y[stack_size].
7428 The mem file is different for this option as well, since it
7429 makes no sense of talking about DSEG lenght.
7431 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7433 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7434 in certain cases, e.g. when ROM assignment, patch provided
7435 from Albert den Haan.
7437 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7990 not occur if the control variable is involved with a
7991 relational operator.

8480 A few small changes that speed up the peephole optimizer.
8484 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8486 Try to make the peephole optimizer smarter by maintaining
8487 an association between the assembly source code and the
8488 iCodes that originated them. Put this information to use
8489 with a new peephole rule condition "notVolatile" so that

8495 * src/mcs51/peeph.def
8497 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8501 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8502 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8503 if the left or right operand symbols have the accuse flag set.
8505 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8507 Changed the type of the result of the ! (NOT) operator to char;
8508 previously it returned the same type as the source. This allows
8509 us to eliminate all the genFloatNot functions (all of its target
8510 implementations were very buggy) since !float can use the same
8513 * src/SDCCicode.c (ast2iCode): ! returns char

8522 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8523 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8524 during interrupts. Ensure WSAVE is located at a shared bank address.
8525 2. Fixed page selection in some places
8526 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8527 the registers name strings.
8528 4. Fixed "signed / unsigned compare" compiler warnings.
8529 5. The PIC port manages its own allocation of the general purpose
8530 registers, but makes no attempt to reuse them. As a result when
8531 compiling it soon runs out of general purpose registers. Some
8532 additional code was added to the files pcode.c and device.c to walk
8533 through the function call tree and rename the registers so that they
8543 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

8550 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8552 Made bitfield a distinct type from bit so that bitfields
8553 convert as per ANSI C and bits retain their traditional
8554 boolean style behaviour. Implemented bitfield support in
8562 * src/ds390/gen.c: bit v bitfield split
8563 * src/z80/gen.c: New support for bitfields
8564 * support/regression/tests/bitfields.c: reenabled z80,
8567 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8569 Rules 246.x, 247.x relate to bitfields, the others speed up
8570 access to xdata mapped I/O devices.
8572 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8574 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8576 Cleaned up genPackBits and genUnpackBits and added two helper
8577 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8578 for literal assignments in genPackBits (thanks to Frieder for
8584 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8586 Fixed bug #748310 (pointer to function type mishandled when the
8587 function name is omitted). Also fixed a SIGSEGV when a function
8588 attribute (reentrant, etc) is used on a non-function or on a
8589 function but misplaced before the parameter list.

8616 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8618 Made the constant following the "interrupt" keyword optional. If
8619 omitted, the function will not automatically be given an entry
8620 in the interrupt vector table (similar to #pragma NOIV, but
8621 less syntacticly kludgy). The interrupt number is also now
8622 range checked. Also fixed a bug in the high order bit example

9098 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
9099 the regression tests I'm not brave enough to enable 245.b, 245.c
9100 * doc/sdccman.lyx: added latex preamble for hyperref package.
9101 Using pdflatex this will give you a hyperlinked pdf file with
9102 bookmarks. (prepend '%' before /usepackage if this breaks something)

9149 added --disable-pic16-port
9150 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9151 * src/SDCCmain.c: linkOptions is changed to set *,
9152 added if/endif conditional macros to remove options help
9153 messages from optionsTable when a port is not configured, added
9154 support for the PIc16 port in the ports table, when executing
9155 the compiler with no port specified on command line, a default
9156 port is selected with the new macro DEFAULT_PORT which is
9157 defined in port.h, in setDefaultOptions() linkOptions is removed
9158 from initialization assignment, since now it is a set,
9159 parseCmdLine uses setParseWithComma for linkOptions, in
9160 linkEdit() linkOptions are accessed with new function indexSet()
9161 which returns the i'th item of a set variable. See SDCCset.c, in
9162 linkEdit() when calling buildCmdLine(), added linkOptions as
9163 last argument. Now users can pass arguments to gplink via the
9164 -Wl option, main() uses pic16glue() to glue up pic16 programs

9176 * src/pic16/glue.c: commented out some error producing lines
9177 * src/pic16/main.c: __config directives are commented out to stop
9178 gpasm complaining and test the linkage with gplink, _linkCmd and
9179 _asmCmd changed to be more gplink and gpasm friendly
9180 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9181 produced an error when parsed, peep rule 12 is added to utilize
9182 movff, but it is commented out since the pCode does not support
9183 yet a command with 2 address arguments
9185 2003-05-18 <johan AT balder>
9187 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9214 2003-05-11 Borut Razem <borut.razem AT siol.net>
9216 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9217 the path of bin directory, so that PATH is the only env. variable, which has to be set
9218 in case of standard installation.
9219 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

10248 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10250 * in \sdcc\as\mcs51\ changed these files in order to create an
10251 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10252 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10253 following files to include the previous two files: aslink.dsp,
10254 Makefile.aslink, Makefile.bcc, and Makefile.in.
10256 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10257 .adb instead of .cdb
10259 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10261 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10262 value from option --iram-size.
10264 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10266 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10269 2002-09-18 <wiml AT hhhh.org>
10271 * SDCClrange.h: exposed setFromRange() and setToRange()
10272 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10273 packRegsForAccUse() (bug 542397)
10274 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10275 multiple times and emitting the fetch operations more than once
10276 added aopGetUsesAcc() function to allow binary operators to
10277 fetch their operands in the correct order; made genMinus() emit
10278 compact code for X = LITERAL - Y
10280 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10281 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10282 sprintf() in line 1267.
10284 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10285 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10288 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10289 Changes to aslink (All the changes are marked with 'JCF'):
10291 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10294 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10295 area BSEG. Also moves, if possible, the DATA area down into the internal
10296 ram so more space is available.
10298 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10301 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10302 not bytes. Function summary() which creates a memory usage summary
10303 file with extension .mem. Reports of overlaping stack and small stack
10304 size. If the space for the stack is less than 16 bytes aslink trows a
10307 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10308 the 8051. Option 'y' for memory summary output file.
10310 Changes to sdcc (All the changes are marked with 'JCF'):
10312 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10314 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10315 overlaying area for it (uses RegBankUsed[4]).
10317 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10318 bank zero as used by default. By default aslink locates the stack
10319 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10320 the creation of the .mem file. Delegates the allocation of data area
10321 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10322 the begining of the stack area to aslink.
10324 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10325 glue() in SDCCglue.c creates an area for it.
10327 2002-09-03 Borut Razem <borut.razem AT siol.net>
10328 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10329 sdcc/src/pic/glue.c:
10330 introduced atexit() handler for teporay files removal in case of
10331 errors, assertions, ...
10333 2002-08-29 Borut Razem <borut.razem AT siol.net>
10334 * sdcc/support/cpp2/auto-host_vc_in.h:
10335 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10336 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10337 Maybe there is a similar problem with BORLANDC? It should be checked!
10339 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10340 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10341 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10342 was not executed, and the compiler (cl) launched a warning:
10343 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10345 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10346 * src/SDCCglue.c (printIvalArray): iterative calculation of array length

10358 - added Release configuration in VS projects
10359 - review of compiler an linker options
10360 - VC .exe files are generated in bin_vc directory, not to interfere
10361 with binaries generated from other projects (cygwin, mingw, bcc ...)
10363 * sdcc/src/yacc.dsp: added
10365 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10366 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10367 and insert the version number definitions from .version
10369 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10371 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10372 added - genarate auto-host.h using auto-host_vc_in.h as template
10375 removed from CVS, generated automatically
10377 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10378 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10380 2002-08-11 Borut Razem <borut.razem AT siol.net>
10381 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10383 2002-08-10 Borut Razem <borut.razem AT siol.net>
10384 * src/SDCCmain.c (main):
10385 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10386 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10387 The consequence was that some temporary files were not removed.
10390 unification of code in functions tempfilename() and tempfile():
10391 function tempnam() is defined in Visual Studio 6.0 and .NET
10393 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10395 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10396 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10397 - removed compiler command line option /WX: Treats all warnings as errors
10398 - update a list of source files, included into the project
10400 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10401 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10402 changed project type to Generic Project so that can be correcly converted to VS.NET project
10404 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10406 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

10410 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10411 added return 0 statements after assert() to make compiler happy
10413 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10414 added newline in the def file to keep MSC compiler satisfied
10416 * sdcc/src/z80/gen.c:
10417 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10418 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10419 - solved MSC error in function aopDump()
10421 * sdcc_vc.h: define PREFIX as "\\sdcc"

10599 Previous fix was not good. basic blocks that have "break" or "return" are
10600 not really partof a loop , but live ranges used in these blocks should
