353 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
355 Enabled VPATH feature: changed nearly all Makefiles (149 files).
356 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
358 One basic decision: e.g. src/clean.mk includes further files. In order
359 to make this work there are two solutions:
360 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
361 run configure on them. This way they can use
362 'include $(srcdir)/port-clean.mk'
363 - always include clean.mk by the Makefile at the same level. To avoid
364 that `make clean` tries to include and build Makefile.dep the
365 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
366 implemented, because now even `make uninstall` doesn't create
367 Makefile.in. clean.mk could be eliminated by pasting it in
370 * debugger/mcs51/Makefile.in: build own objects from library sources
371 (SLIB, SDCC) in current directory
373 * configure, configure.in: renamed --disable-device-lib-build in
374 --disable-device-lib; added --enable-doc, the required tools are
375 searched by configure; added result message; the toolchain for the
376 belonging ports are now only built, if the port is enabled.
378 * support/regression/*: all output is written in directory gen, because
379 the fwk and ports directories don't livet in the build tree using vpath
381 * doc/sdccman.lyx: renamed --disable-device-lib-build to
382 --disable-device-lib, added --enable-doc, added section VPATH
384 * sim/ucsim/configure.in,
385 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
386 z80 are enabled by default
388 2006-04-24 Raphael Neider <rneider AT web.de>
390 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
391 to config word, "pic14_"-prefixed some extern functions
392 (pic14_emitConfigWord): emit __config directive(s) if assignment to
393 config word has been found
394 * src/pic/device.h: added prototypes
395 * src/pic/pcode.c: added "pic14_"-prefix where needed

415 2006-04-24 Borut Razem <borut.razem AT siol.net>
417 * device/examples/main8051.c: deleted - it was removed from CVS
418 24.mar.2000 and after that modified 18.feb.2001, so it reappered
419 after the transition to Subversion
420 * src/SDCCalloc.h: deleted - it was removed from CVS

676 the left operand is shorter than the result (c* = lit-c* + int),
678 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
681 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
683 * src/.version: increased version number to 2.5.5
684 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
685 linking is done manually in pic16 port's _linkEdit,
686 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
687 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,

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

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

770 'xinst' for initial support for Extended Instruction Support,
771 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
772 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
773 port->fun_prefix anymore (may change later),
774 (genFunction, genEndFunction): do not store/restore local registers for
775 _main (this should take care the --main-return command line option in
777 (genOr): removed some legacy pic-port instructions,
778 * src/pic16/genarith.c (genAddLit): re-enabled old code because
779 performing operations with SFR's causes data to be written more than
780 once to each SFR. Perhaps SFRs should be handled in special cases...
781 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
783 * src/pic16/main.c (_process_pragma): stack bound checking did not take
784 into account for stack starting position,
785 (struct OPTIONS pic16_optionsTable): added command line argument
786 --extended or -y for Extended Instruction Support,
787 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
788 (deassignLRs): *** perhaps the most important change, old 'for' code
789 (commented out for reference), didn't account for some registers which
790 were left marked 'not free' after a pointer operation. The change
791 reduces register usage a lot in some cases

3056 * (genCmp): adapted to new genSkipc semantics
3057 * src/pic16/genutils.c (pic6_genCmp_special): removed side effect
3058 on rIfx (genCmp was broken)
3060 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3062 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
3063 * src/z80/main.c (_keywords[]),
3064 * src/SDCCglobal.h (struct options),
3066 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3067 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3068 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3069 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3070 always available in leading double underscore form. The C99 support is
3071 mostly missing, but it's a start.
3072 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3073 reserved identifier "__data".
3075 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
3077 * src/mcs51/peeph.def: fixed bug 1170013

3119 immedDom() returning wrong block; probably fixes bug #1160833)
3121 2005-03-20 Borut Razem <borut.razem AT siol.net>
3123 * support/scripts/inc2h.pl: WIN32 port

3127 * device/lib/makefile.in: added abs.c and labs.c
3129 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
3131 * device/include/stdint.h: added
3132 * device/lib/abs.c: added

3151 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3153 * device/lib/printf_large.c: removed inline assembly for portability and
3154 readability. Use printf_fast if speed or size are more important.
3155 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3156 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3158 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3160 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3161 prevent compiler warning
3163 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3165 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3166 moved to level 0 and declared as static. Also they are explicit
3167 placed in access bank. This was necessery because some times they
3168 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3169 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3170 optimizations. Currently only compare to unsigned char is implemented,
3171 * src/pic16/gen.c: added fReturnIdx array,
3172 * (struct resolvedIfx) is moved to gen.h and made public,
3173 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3174 * (aopForSym): added an optimization to directly store in stack of
3175 the operand of a SEND iCode,
3176 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3177 but as registers instead (AOP_REG) using the fReturnIdx array,
3178 * (pic16_freeAsmop): remove the freed register from the
3179 _G.sregsAlloc field,
3180 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3181 a compare of 'WREG',
3182 * (pic16_popGetTempRegCond): changed function prototype, now
3183 function takes also a bitVector argument v which holds the current
3184 set of registers that are allocated for stack access by aopForSym,
3185 registers allocated in aopForSym for accessing stack symbols are not
3186 any more part of the functions usedRegs field,
3187 * (genCall): some times aopOp is called for a stack variable to be
3188 send, aopForSym might perform the push, if this is true make sure
3189 that genCall doesn't push the variable twice by testing _G.resDirect,
3190 * (genFunction): changed testing for unspecified interrupt number
3191 from 256 to INTNO_UNSPEC,
3192 * modified selection scheme of frame pointer generation. Previously
3193 if function did use local registers a frame pointer was generated,
3194 now a frame pointer is generated only if function has arguments
3195 (that need PLUSW2 register access), or has stack arguments, or the
3196 compiler is not instructed to omit the frame pointer,
3197 * (genEndFunction): before restoring local registers that were saved
3198 in the function preamble, also restore the registers that *might*
3199 have been allocated for stack access,
3200 * (genRet): removed some old comments,
3201 * (genCmp, the active (RN's) version): added a call to the
3202 pic16_genCmp_special function to perform the compare with a more
3203 robust and optimized way,
3204 * (genInline): a feature has been added in inline code generation,
3205 which allows a wildcard variable substitution when writing inline
3206 assembly. Code is incomplete and experimental therefore undocumented,
3207 * (genCast): changed order of aopOp for result and right to allow
3208 aopForSym to directly load the result if possible,
3209 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3210 perform an optimized compare on some selected special occasions,
3211 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3212 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3213 generate an IVT any more,
3214 * src/pic16/main.c (pic16_optionsTable): added command line option
3216 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3217 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3219 * src/pic16/NOTES: Raphael Neider added in list of active developers
3220 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3221 jumptable_end to prevent bug #,
3222 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3223 inCond and outCond fields,
3224 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3225 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3226 turn off register spilling,
3227 * (packRegsForOneUse): synced with other ports' versions although it
3228 is not used currently,
3229 * (pic16_packRegisters): added an optimization while reading
3230 structure bitfields, some registers may be saved (malloc code is
3231 decreased by 80 bytes)
3233 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3235 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3236 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3237 this can be optimized more?
3239 2005-03-10 Raphael Neider <rneider AT web.de>
3241 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3242 genNearPointerGet): (hopefully) fixed access to bitfields via
3243 pointers (p->bitN = x; and x = p->bitN; failed)
3245 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
3247 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

3288 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
3289 to keep the correct label reference count when adding/removing references
3290 to labels. A peephole file using this is appended to patch #1144962.

3422 * src/pic16/main.c (_process_pragma): fixed another malloc bug
3423 (sizeof(sectNames) changed to sizeof(sectName))
3424 Both patches fix segfaults under MinGW.

3431 of (byte sized) temporaries (assign them to WREG for now)
3432 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
3433 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
3434 this might fix SIGSEGVs on MinGW...
3435 * src/SDCCopt.c (killDeadCode): restored original behaviour
3436 (volatile operands might get thrown away though)
3438 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
3440 * src/pic16/gen.c: fixed bug #1106975,

3899 2004-11-25 Vangelis Rokas <vrokas AT otenet.gr>
3901 * src/pic16/device.h,
3902 * src/pic16/genarith.c,
3905 * src/pic16/pcode.c: applied patches #1068154 and #1070213
3907 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
3909 Large cummulative patch for pic16 port.
3910 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
3911 to call when a stack overflow occurs,
3912 * (malloc.h): added CVS Id tag,
3913 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3915 * added libc directory. The current version of LibC contains string
3916 functions, ctype functions and macros and some functions of the
3917 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3918 be extensively tested in the future. Standard disclaimer here.
3919 Library is not automatically build yet. But one can build it by
3920 invoking 'make' inside the libc directory.
3921 * added ADC library under libio. Preliminary version yet.
3923 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
3924 * src/pic16/gen.c (aopForRemat): asmop size is filled by
3925 aopForRemat() now and not by pic16_aopOp(),
3926 * (pic16_popGetTempReg): removed warning messgae when allocating
3927 temporary registers, its a buggy feature and will be removed,
3928 * (pic16_popGet): set register instance field in AOP_CRY,
3929 * (pic16_outBitC): fixed for results in size greater than 1,
3930 * (genUminusFloat): fixed for pic16, ported code from mcs51,
3931 * (pic16_storeForReturn): optimized return of 0,
3932 * (genCmp): experimental code for new genCmp which uses PIC18's
3933 special compare&skip instructions. Initial tests fail some times
3934 with variables grater than 1 byte in size, so new code is disabled,
3935 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3937 * (genCast): began a fix to optimize the casting of a bit to another
3938 bit, now assigning a bitfield to another bitfield will fail, sorry,
3939 * src/pic16/main.c: disabled the use of lr-support feature,
3940 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
3941 * added some function prototypes, added function _debugf prototype,
3942 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
3943 bits with offset (case PO_GPR_BIT),
3944 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
3946 * (isBankInstruction): modified to return 0 for no banking instruction,
3947 and 1 for banking instruction,
3948 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3949 caused stop processing pCodes after a inline assembly block,
3950 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
3951 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
3952 registers when it shouldn't,
3953 * src/pic16/ralloc.c (allocReg): add preliminary support for
3954 supporting a limited set of temporary registers,
3956 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3958 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
3959 genDataPointerSet): ensure assignments always copy in MSB to LSB
3961 (loadRegFromAop): recognize CLRH optimization,
3962 (genFunction): optimize RECEIVE iCodes in reentrant functions
3964 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3966 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
3967 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
3969 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

3975 * device/lib/_gptrget.c (_gptrget),
3976 * device/lib/_gptrgetc.c (_gptrgetc),
3977 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
3978 instead of sjmp to ret
3979 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
3980 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
3982 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

6961 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6963 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6964 loaded with the linker search paths (-L arguments) and the libraries
6965 to be linked with the current source (-l arguments). Changes
6966 currently will affect only the pic16 port.
6967 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6968 include path the port specific paths and port specific libraries,
6969 * gplink command now contains the $3 argument,
6970 * src/pic16/device.h,
6971 * src/pic16/device.c,: structure PIC_device is made public and
6972 renamed to PIC16_device, the same for variable Pics which is renamed

6987 Documenting changes from previous commits.
6988 * configure.in (version 1.56),
6989 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6990 when generating output files to configure the pic16 library,
6991 but now I've commented it out, since gputils aren't installed in the
6992 SF compile farm, so library won't compile
6994 * device/lib/Makefile.in (version 1.56): initially I've added in
6995 target 'all' the prerequestive 'model-pic16' so it compiled the
6996 pic16 library, but now I've commented it out for the same reasons
6998 * added targets 'model-pic16' and 'objects-pic16' to compile the
7000 * added target 'port-specific-objects-pic16' to handle the
7001 generated libraries and copy them into the build/ directory
7002 * added target 'clean-intermediate-pic16' to clean intermediate
7003 files into pic16 directory
7004 * in target 'installdirs' added line to create directory pic16 in

7025 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7026 option so that it actually works. Made it specific to the z80, since
7027 the gbz80 doesn't have these kinds of I/O ports.
7029 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7031 * device/include/z180.h,

7055 via literal number. The symbol is placed in the corresponding
7056 position of the data ram
7057 * (pic16_dump_section): relocatable and absolute uninitialized
7058 data are now emitted in sorted order to reduce section naming,
7059 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7060 weren't marked as being in the access bank,
7062 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7064 Added portion of GNU PIC Library under the directory
7065 device/include/pic16 and device/lib/pic16. These files
7066 contain the declarations of SFRs for the PIC18Fxx2 devices.
7067 The directory is initialized via configure from toplevel.
7069 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
7071 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

7097 all over. Telling LaTeX to be less strict with word spacing
7098 to better keep the right margin. Changed some notes about
7099 maintainance of the ports in section 3.2.1 - is it OK like this?
7101 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7139 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7141 * src/pic16/peeph.def: all peepholes with movff are commented out,
7142 because there is a problem in the pcode peep optimizer,
7143 * src/pic16/ralloc.c: the register allocator can now reuse local

7145 * src/pic16/ralloc.h: added flag isLocal in structure regs,
7147 Added file src/pic16/NOTES with information about program writing on
7148 the current port version.

7180 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7183 * src/z80/main.c: added missed needLinkerScript flags (more than
7184 one port structure defined in these file)
7185 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

7207 * (pic14emitOverlay): modified to emit a commented overlay segment
7208 directive when no overlay data exist
7209 * (picglue): modified to emit uninitialized data segment
7210 according to udata_section_name

7220 2004-01-07 Borut Razem <borut.razem AT siol.net>
7222 * support/scripts/sdcc.nsi: update PATH
7223 * support/scripts/sdcc.ico: craeted

7230 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7232 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
7234 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

7236 include information about variables allocated to the overlay
7239 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7241 * as/mcs51/lkmain.c: Help about -Y option

7253 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7255 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7256 (default behaviour).
7258 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7260 A python script to validate compiler diagnostic messages. It can be
7261 used to verify that sdcc complains about bad c source code and
7262 gives a good location of the error.
7263 * support/valdiag/Makefile,
7264 * support/valdiag/valdiag.py,
7265 * support/valdiag/tests/*
7267 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7269 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

7280 * src/common.h: added ifndef/define/endif macros
7281 around the header file.
7282 Bug reported from Jesus Calvino-Fraga
7284 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7286 * sdcc.spec: updated
7287 * device/include/Makefile.in: don't install CVS directories
7288 * device/lib/Makefile.in: added removal of CVS directories after install
7289 * doc/Makefile: fixed install, added local_icons
7290 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7291 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7292 * src/ds390/gen.c (genRightShift): fixed bug #870788
7293 * src/SDCCast.c (decorateType): fixed bug #870781
7295 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7297 PIC16 port related changes:
7298 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7299 added variable stackPos,
7301 * gen.c: genCall, assignResultValue: added support for
7302 pushing/retrieving function parameters to/from stack,
7303 genFunction,genEndFunction: setup stack frame for the
7305 genAddrOf: will be changed according to bug 863624
7307 * added files genutils.c and genutils.h which contain gen*
7308 debugged and optimised functions extracted from gen.c
7310 * glue.c: added variable 'externs' which holds extern symbols,
7311 pic16emitRegularMap: is modified to properly handle relocatable
7312 symbols under the new scheme,
7313 pic16createInterruptVect: is modified
7314 pic16printPublics: is modified to emit 'global' assembler directives,
7315 added pic16_printExterns to print extern symbols,
7316 pic16glue: initializes stack/frame pointer in the beginning of
7317 the assembly output. Temporary hack, will be corrected later,
7318 because gplink yet does not support stack and SDCC does not
7319 yet support a type of crt0.o object to create the final binary.
7321 * Removed many lines that contain 8051 legacy code.
7322 * The code is finally placed under a 'code' directive.
7323 * Added port specific options.
7325 * _process_pragma: simplified since now we do not need *special*
7326 include file to define SFR registers. But a separate header
7327 will be needed. This will be developed later.
7328 * _pic16_parseOptions: added, parses port specific options:
7329 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7330 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7331 --preplace-udata-with=
7333 * _pic16_setDefaultOptions: modified to initialize section names,
7334 but hack is temporarly out of order since it needs improvement.
7335 * _pic16_genAssemblerPreamble: configuration words are emitted by
7336 their address instead of their name. This part is incomplete and
7337 supports only the 18Fxx2 devices. Other devices will emit an error
7338 during assembly since they do not contain the same set of config
7340 * _pic16_genIVT: is modified,
7342 * pcode.c: added definitions for some hardware registers that are needed
7344 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7345 All PCI entries are updated. Now LFSR is supported.
7346 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7347 * added pic16_newpCodeOpLit2 to support instructions with
7348 two literal arguments
7349 * pic16_pCode2str: corrected code that emits assembler instructions
7350 with two literal operands and those that have an access bit modifier
7351 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7352 this fixes a bug which caused some labels to be lost, when an
7353 assembler directive was added, i.e. banksel,
7354 * pic16_FixRegisterBanking: improved logic that causes the insertion
7356 * InlineFunction: functions that are called once, are not any more
7357 inlined. This can be a port option in the future,
7359 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7361 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7362 hold the corresponding uninitialized symbols,
7363 * pic16_allocProcessorRegister: registers have explicit marked the
7365 * pic16_allocInternalRegister: registers are explicit marked as
7367 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7368 processing list, so bit registers were lost,
7371 * ralloc.h: added field 'accessBank' and original symbol operand
7372 in register definition,
7373 * removed the field isMapped from register definition,
7375 ** Several functions have been removed from various sources:
7376 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7377 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7378 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7379 pic16_assignRelocatableRegisters
7381 ** others have been introduced:
7382 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7383 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7385 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7387 * support/scripts/inc2h.pl: changed definition of BIT_AT
7388 to emit 'sbit at' instead of 'bit at'. This was a request.
7390 PIC16 port related preliminary changes:
7391 * gen.c: prefixed function popRegFromString with
7392 pic16_ and all references to it corrected
7393 * pcode.c: all pic16_pc_* hardware registers prefixed
7394 with underscore (_),
7395 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7396 * ralloc.c: newReg(): when register is REG_SFR then
7397 set address to rIdx,
7398 pic16_allocProcessorRegister(): marks register wasUsed=0
7399 pic16_writeUsedRegs(): added a call to assign processor
7400 registers via pic16_assignFixedRegisters
7402 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7404 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7405 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7406 variables in unused register banks. Also the SSEG is placed
7407 wherever there is enough space for it, and IDATA can be anywhere
7408 in internal RAM. For now compile using -Wl-Y[stack_size].
7409 The mem file is different for this option as well, since it
7410 makes no sense of talking about DSEG lenght.
7412 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7414 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7415 in certain cases, e.g. when ROM assignment, patch provided
7416 from Albert den Haan.
7418 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7963 2003-10-30 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7965 Fixed a number of problems revealed by bug #827883.
7966 * src/SDCCloop.c (loopInvariants): Spill location of the
7967 result operand should be recomputed if extracted from
7968 a loop. Also, don't extract assignments of an iTemp
7970 * src/SDCCast.c (isConformingBody): loop reversal should
7971 not occur if the control variable is involved with a
7972 relational operator.

8461 A few small changes that speed up the peephole optimizer.
8465 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8467 Try to make the peephole optimizer smarter by maintaining
8468 an association between the assembly source code and the
8469 iCodes that originated them. Put this information to use
8470 with a new peephole rule condition "notVolatile" so that
8471 the rules can be aggressive yet still safe.
8476 * src/mcs51/peeph.def
8478 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8489 previously it returned the same type as the source. This allows
8490 us to eliminate all the genFloatNot functions (all of its target
8491 implementations were very buggy) since !float can use the same

8503 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8504 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8505 during interrupts. Ensure WSAVE is located at a shared bank address.
8506 2. Fixed page selection in some places
8507 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8508 the registers name strings.
8509 4. Fixed "signed / unsigned compare" compiler warnings.
8510 5. The PIC port manages its own allocation of the general purpose
8511 registers, but makes no attempt to reuse them. As a result when
8512 compiling it soon runs out of general purpose registers. Some
8513 additional code was added to the files pcode.c and device.c to walk
8514 through the function call tree and rename the registers so that they
8524 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

8531 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8533 Made bitfield a distinct type from bit so that bitfields
8534 convert as per ANSI C and bits retain their traditional
8535 boolean style behaviour. Implemented bitfield support in
8543 * src/ds390/gen.c: bit v bitfield split
8544 * src/z80/gen.c: New support for bitfields
8545 * support/regression/tests/bitfields.c: reenabled z80,
8548 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8550 Rules 246.x, 247.x relate to bitfields, the others speed up
8551 access to xdata mapped I/O devices.
8553 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8555 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8557 Cleaned up genPackBits and genUnpackBits and added two helper
8558 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8559 for literal assignments in genPackBits (thanks to Frieder for
8565 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8567 Fixed bug #748310 (pointer to function type mishandled when the
8568 function name is omitted). Also fixed a SIGSEGV when a function
8569 attribute (reentrant, etc) is used on a non-function or on a
8570 function but misplaced before the parameter list.

8597 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8599 Made the constant following the "interrupt" keyword optional. If
8600 omitted, the function will not automatically be given an entry
8601 in the interrupt vector table (similar to #pragma NOIV, but
8602 less syntacticly kludgy). The interrupt number is also now
8603 range checked. Also fixed a bug in the high order bit example

9079 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
9080 the regression tests I'm not brave enough to enable 245.b, 245.c
9081 * doc/sdccman.lyx: added latex preamble for hyperref package.
9082 Using pdflatex this will give you a hyperlinked pdf file with

9099 Applied patch from bug 737905 (renamed yylineo to mylineno):
9106 * src/pic16/pcode.c: Cleaned warnings
9107 * src/pic16/pcodeflow.c: Cleaned warnings
9108 * src/pic16/pcoderegs.c: Cleaned warnings

9124 it can be defined with CFLAGS when running configure
9125 * src/SDCCmain.c: fixed compiling + linking with object files
9127 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

9130 added --disable-pic16-port
9131 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9132 * src/SDCCmain.c: linkOptions is changed to set *,
9133 added if/endif conditional macros to remove options help
9134 messages from optionsTable when a port is not configured, added
9135 support for the PIc16 port in the ports table, when executing
9136 the compiler with no port specified on command line, a default
9137 port is selected with the new macro DEFAULT_PORT which is
9138 defined in port.h, in setDefaultOptions() linkOptions is removed
9139 from initialization assignment, since now it is a set,
9140 parseCmdLine uses setParseWithComma for linkOptions, in
9141 linkEdit() linkOptions are accessed with new function indexSet()
9142 which returns the i'th item of a set variable. See SDCCset.c, in
9143 linkEdit() when calling buildCmdLine(), added linkOptions as
9144 last argument. Now users can pass arguments to gplink via the
9145 -Wl option, main() uses pic16glue() to glue up pic16 programs
9146 * src/SDCCpeeph.c: various changes to support pic16

9157 * src/pic16/glue.c: commented out some error producing lines
9158 * src/pic16/main.c: __config directives are commented out to stop
9159 gpasm complaining and test the linkage with gplink, _linkCmd and
9160 _asmCmd changed to be more gplink and gpasm friendly
9161 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9162 produced an error when parsed, peep rule 12 is added to utilize
9163 movff, but it is commented out since the pCode does not support
9164 yet a command with 2 address arguments
9166 2003-05-18 <johan AT balder>
9168 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9193 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
9195 2003-05-11 Borut Razem <borut.razem AT siol.net>
9197 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9198 the path of bin directory, so that PATH is the only env. variable, which has to be set
9199 in case of standard installation.
9200 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

10216 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10217 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

10224 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
10226 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10227 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10229 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10231 * in \sdcc\as\mcs51\ changed these files in order to create an
10232 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10233 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10234 following files to include the previous two files: aslink.dsp,
10235 Makefile.aslink, Makefile.bcc, and Makefile.in.
10237 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10238 .adb instead of .cdb
10240 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10242 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10243 value from option --iram-size.
10245 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10247 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10250 2002-09-18 <wiml AT hhhh.org>
10252 * SDCClrange.h: exposed setFromRange() and setToRange()
10253 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10254 packRegsForAccUse() (bug 542397)
10255 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10256 multiple times and emitting the fetch operations more than once
10257 added aopGetUsesAcc() function to allow binary operators to
10258 fetch their operands in the correct order; made genMinus() emit
10259 compact code for X = LITERAL - Y
10261 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10262 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10263 sprintf() in line 1267.
10265 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10266 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10269 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10270 Changes to aslink (All the changes are marked with 'JCF'):
10272 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10275 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10276 area BSEG. Also moves, if possible, the DATA area down into the internal
10277 ram so more space is available.
10279 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10282 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10283 not bytes. Function summary() which creates a memory usage summary
10284 file with extension .mem. Reports of overlaping stack and small stack
10285 size. If the space for the stack is less than 16 bytes aslink trows a
10288 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10289 the 8051. Option 'y' for memory summary output file.
10291 Changes to sdcc (All the changes are marked with 'JCF'):
10293 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10295 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10296 overlaying area for it (uses RegBankUsed[4]).
10298 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10299 bank zero as used by default. By default aslink locates the stack
10300 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10301 the creation of the .mem file. Delegates the allocation of data area
10302 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10303 the begining of the stack area to aslink.
10305 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10306 glue() in SDCCglue.c creates an area for it.
10308 2002-09-03 Borut Razem <borut.razem AT siol.net>
10309 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10310 sdcc/src/pic/glue.c:
10311 introduced atexit() handler for teporay files removal in case of
10312 errors, assertions, ...
10314 2002-08-29 Borut Razem <borut.razem AT siol.net>
10315 * sdcc/support/cpp2/auto-host_vc_in.h:
10316 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10317 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10318 Maybe there is a similar problem with BORLANDC? It should be checked!
10320 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10321 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10322 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10323 was not executed, and the compiler (cl) launched a warning:
10324 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10326 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10327 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10329 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10330 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10332 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10333 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10334 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10335 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10336 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10337 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10338 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10339 - added Release configuration in VS projects
10340 - review of compiler an linker options
10341 - VC .exe files are generated in bin_vc directory, not to interfere
10342 with binaries generated from other projects (cygwin, mingw, bcc ...)
10344 * sdcc/src/yacc.dsp: added
10346 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10347 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10348 and insert the version number definitions from .version
10350 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10352 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10353 added - genarate auto-host.h using auto-host_vc_in.h as template
10356 removed from CVS, generated automatically
10358 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10359 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10361 2002-08-11 Borut Razem <borut.razem AT siol.net>
10362 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10364 2002-08-10 Borut Razem <borut.razem AT siol.net>
10365 * src/SDCCmain.c (main):
10366 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10367 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10368 The consequence was that some temporary files were not removed.
10371 unification of code in functions tempfilename() and tempfile():

10580 Previous fix was not good. basic blocks that have "break" or "return" are
10581 not really partof a loop , but live ranges used in these blocks should
