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

418 (pic14createInterruptVect): moved generating __config directives away

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

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

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

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

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

3075 on rIfx (genCmp was broken)
3077 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3079 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
3080 * src/z80/main.c (_keywords[]),
3081 * src/SDCCglobal.h (struct options),
3083 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3084 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3085 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3086 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3087 always available in leading double underscore form. The C99 support is
3088 mostly missing, but it's a start.
3089 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3090 reserved identifier "__data".
3092 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
3094 * src/mcs51/peeph.def: fixed bug 1170013

3136 immedDom() returning wrong block; probably fixes bug #1160833)
3138 2005-03-20 Borut Razem <borut.razem AT siol.net>
3140 * support/scripts/inc2h.pl: WIN32 port

3144 * device/lib/makefile.in: added abs.c and labs.c
3146 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
3148 * device/include/stdint.h: added
3149 * device/lib/abs.c: added

3168 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3170 * device/lib/printf_large.c: removed inline assembly for portability and
3171 readability. Use printf_fast if speed or size are more important.
3172 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3173 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3175 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3177 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3178 prevent compiler warning
3180 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3182 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3183 moved to level 0 and declared as static. Also they are explicit
3184 placed in access bank. This was necessery because some times they
3185 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3186 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3187 optimizations. Currently only compare to unsigned char is implemented,
3188 * src/pic16/gen.c: added fReturnIdx array,
3189 * (struct resolvedIfx) is moved to gen.h and made public,
3190 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3191 * (aopForSym): added an optimization to directly store in stack of
3192 the operand of a SEND iCode,
3193 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3194 but as registers instead (AOP_REG) using the fReturnIdx array,
3195 * (pic16_freeAsmop): remove the freed register from the
3196 _G.sregsAlloc field,
3197 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3198 a compare of 'WREG',
3199 * (pic16_popGetTempRegCond): changed function prototype, now
3200 function takes also a bitVector argument v which holds the current
3201 set of registers that are allocated for stack access by aopForSym,
3202 registers allocated in aopForSym for accessing stack symbols are not
3203 any more part of the functions usedRegs field,
3204 * (genCall): some times aopOp is called for a stack variable to be
3205 send, aopForSym might perform the push, if this is true make sure
3206 that genCall doesn't push the variable twice by testing _G.resDirect,
3207 * (genFunction): changed testing for unspecified interrupt number
3208 from 256 to INTNO_UNSPEC,
3209 * modified selection scheme of frame pointer generation. Previously
3210 if function did use local registers a frame pointer was generated,
3211 now a frame pointer is generated only if function has arguments
3212 (that need PLUSW2 register access), or has stack arguments, or the
3213 compiler is not instructed to omit the frame pointer,
3214 * (genEndFunction): before restoring local registers that were saved
3215 in the function preamble, also restore the registers that *might*
3216 have been allocated for stack access,
3217 * (genRet): removed some old comments,
3218 * (genCmp, the active (RN's) version): added a call to the
3219 pic16_genCmp_special function to perform the compare with a more
3220 robust and optimized way,
3221 * (genInline): a feature has been added in inline code generation,
3222 which allows a wildcard variable substitution when writing inline
3223 assembly. Code is incomplete and experimental therefore undocumented,
3224 * (genCast): changed order of aopOp for result and right to allow
3225 aopForSym to directly load the result if possible,
3226 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3227 perform an optimized compare on some selected special occasions,
3228 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3229 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3230 generate an IVT any more,
3231 * src/pic16/main.c (pic16_optionsTable): added command line option
3233 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3234 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3236 * src/pic16/NOTES: Raphael Neider added in list of active developers
3237 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3238 jumptable_end to prevent bug #,
3239 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3240 inCond and outCond fields,
3241 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3242 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3243 turn off register spilling,
3244 * (packRegsForOneUse): synced with other ports' versions although it
3245 is not used currently,
3246 * (pic16_packRegisters): added an optimization while reading
3247 structure bitfields, some registers may be saved (malloc code is
3248 decreased by 80 bytes)
3250 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3252 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3253 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3254 this can be optimized more?
3256 2005-03-10 Raphael Neider <rneider AT web.de>
3258 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3259 genNearPointerGet): (hopefully) fixed access to bitfields via
3260 pointers (p->bitN = x; and x = p->bitN; failed)
3262 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
3264 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

3305 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
3306 to keep the correct label reference count when adding/removing references
3307 to labels. A peephole file using this is appended to patch #1144962.

3439 * src/pic16/main.c (_process_pragma): fixed another malloc bug
3440 (sizeof(sectNames) changed to sizeof(sectName))
3441 Both patches fix segfaults under MinGW.
3443 2005-01-23 Raphael Neider <rneider AT web.de>

3447 * src/pic16/gen.c (pic16_aopOp,pic16_popGet): added handling
3448 of (byte sized) temporaries (assign them to WREG for now)
3449 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
3450 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
3451 this might fix SIGSEGVs on MinGW...
3452 * src/SDCCopt.c (killDeadCode): restored original behaviour
3453 (volatile operands might get thrown away though)
3455 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
3457 * src/pic16/gen.c: fixed bug #1106975,

3894 Adding support for replacing ljmps with sjmps in jumptables
3895 generated for switch statements. For now you need to set the
3896 environment variable SDCC_SJMP_JUMPTABLE to enable this.

3919 * src/pic16/genarith.c,
3922 * src/pic16/pcode.c: applied patches #1068154 and #1070213
3924 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
3926 Large cummulative patch for pic16 port.
3927 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
3928 to call when a stack overflow occurs,
3929 * (malloc.h): added CVS Id tag,
3930 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3932 * added libc directory. The current version of LibC contains string
3933 functions, ctype functions and macros and some functions of the
3934 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3935 be extensively tested in the future. Standard disclaimer here.
3936 Library is not automatically build yet. But one can build it by
3937 invoking 'make' inside the libc directory.
3938 * added ADC library under libio. Preliminary version yet.
3940 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
3941 * src/pic16/gen.c (aopForRemat): asmop size is filled by
3942 aopForRemat() now and not by pic16_aopOp(),
3943 * (pic16_popGetTempReg): removed warning messgae when allocating
3944 temporary registers, its a buggy feature and will be removed,
3945 * (pic16_popGet): set register instance field in AOP_CRY,

3947 * (genUminusFloat): fixed for pic16, ported code from mcs51,
3948 * (pic16_storeForReturn): optimized return of 0,
3949 * (genCmp): experimental code for new genCmp which uses PIC18's
3950 special compare&skip instructions. Initial tests fail some times
3951 with variables grater than 1 byte in size, so new code is disabled,
3952 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3954 * (genCast): began a fix to optimize the casting of a bit to another
3955 bit, now assigning a bitfield to another bitfield will fail, sorry,
3956 * src/pic16/main.c: disabled the use of lr-support feature,
3957 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
3958 * added some function prototypes, added function _debugf prototype,
3959 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
3960 bits with offset (case PO_GPR_BIT),
3961 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
3963 * (isBankInstruction): modified to return 0 for no banking instruction,
3964 and 1 for banking instruction,
3965 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3966 caused stop processing pCodes after a inline assembly block,
3967 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
3968 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
3969 registers when it shouldn't,
3970 * src/pic16/ralloc.c (allocReg): add preliminary support for
3971 supporting a limited set of temporary registers,
3973 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3975 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
3976 genDataPointerSet): ensure assignments always copy in MSB to LSB
3978 (loadRegFromAop): recognize CLRH optimization,
3979 (genFunction): optimize RECEIVE iCodes in reentrant functions
3981 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3983 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
3984 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
3986 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

3997 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
3999 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

6981 loaded with the linker search paths (-L arguments) and the libraries
6982 to be linked with the current source (-l arguments). Changes
6983 currently will affect only the pic16 port.
6984 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6985 include path the port specific paths and port specific libraries,
6986 * gplink command now contains the $3 argument,

7002 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
7004 Documenting changes from previous commits.
7005 * configure.in (version 1.56),
7006 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7007 when generating output files to configure the pic16 library,
7008 but now I've commented it out, since gputils aren't installed in the
7009 SF compile farm, so library won't compile
7011 * device/lib/Makefile.in (version 1.56): initially I've added in
7012 target 'all' the prerequestive 'model-pic16' so it compiled the
7013 pic16 library, but now I've commented it out for the same reasons
7015 * added targets 'model-pic16' and 'objects-pic16' to compile the
7017 * added target 'port-specific-objects-pic16' to handle the
7018 generated libraries and copy them into the build/ directory
7019 * added target 'clean-intermediate-pic16' to clean intermediate
7020 files into pic16 directory
7021 * in target 'installdirs' added line to create directory pic16 in
7022 the installation path
7024 * device/include/Makefile.in (version 1.11): in target 'install'
7025 added lines to copy all header files to installation path,
7026 * in target 'installdirs' added line create directory for pic16
7027 headers in the installation path
7029 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

7042 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7043 option so that it actually works. Made it specific to the z80, since
7044 the gbz80 doesn't have these kinds of I/O ports.
7046 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7048 * device/include/z180.h,

7054 * device/lib/_strcmp.c,
7055 * device/lib/_strtok.c: fixed pragmas to non-deprecated form
7056 * src/z80/main.c (_process_pragma): add support for pragmas bank and
7057 portmode; added deprecation warning for bank= and protmode= forms.
7058 Also, guard against buffer overflow.
7059 * src/z80/gen.c (aopGet): generate better code for sfr banked read
7061 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7063 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
7064 changed interrupt vector table generation to only emit declared vectors.
7065 * device/include/Makefile.in: added missing backslash
7066 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
7068 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7070 Mainly changes to support compilation of the device libraries
7071 * src/pic16/device.c: stack is allocated via symbol and not
7072 via literal number. The symbol is placed in the corresponding
7073 position of the data ram
7074 * (pic16_dump_section): relocatable and absolute uninitialized
7075 data are now emitted in sorted order to reduce section naming,
7076 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7077 weren't marked as being in the access bank,
7079 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7081 Added portion of GNU PIC Library under the directory
7082 device/include/pic16 and device/lib/pic16. These files
7083 contain the declarations of SFRs for the PIC18Fxx2 devices.
7084 The directory is initialized via configure from toplevel.
7086 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
7088 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
7089 the spilllocations to be compared correctly
7091 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
7093 * src/SDCCast.c (decorateType): fixed bug introduced today
7095 2004-01-12 Borut Razem <borut.razem AT siol.net>

7111 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7113 * doc/sdccman.lyx: Moved and added some sections, small changes
7114 all over. Telling LaTeX to be less strict with word spacing
7115 to better keep the right margin. Changed some notes about
7116 maintainance of the ports in section 3.2.1 - is it OK like this?
7118 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7155 UPPER for immediate operands,
7156 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7158 * src/pic16/peeph.def: all peepholes with movff are commented out,
7159 because there is a problem in the pcode peep optimizer,
7160 * src/pic16/ralloc.c: the register allocator can now reuse local

7162 * src/pic16/ralloc.h: added flag isLocal in structure regs,
7164 Added file src/pic16/NOTES with information about program writing on
7165 the current port version.

7197 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7200 * src/z80/main.c: added missed needLinkerScript flags (more than
7201 one port structure defined in these file)
7202 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

7218 needLinkerScript flag
7220 * src/pic16/gen.c (genAddrOf): fixed bug #863624
7221 * src/pic/glue.c: added variable udata_section_name to
7222 override default uninitialized data segment definition for
7223 devices only with SHAREBANK memory (reported from Erik Epetrich)
7224 * (pic14emitOverlay): modified to emit a commented overlay segment
7225 directive when no overlay data exist
7226 * (picglue): modified to emit uninitialized data segment
7227 according to udata_section_name

7237 2004-01-07 Borut Razem <borut.razem AT siol.net>
7239 * support/scripts/sdcc.nsi: update PATH
7240 * support/scripts/sdcc.ico: craeted

7253 include information about variables allocated to the overlay
7256 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7258 * as/mcs51/lkmain.c: Help about -Y option

7270 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7272 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7273 (default behaviour).
7275 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7277 A python script to validate compiler diagnostic messages. It can be
7278 used to verify that sdcc complains about bad c source code and
7279 gives a good location of the error.
7280 * support/valdiag/Makefile,
7281 * support/valdiag/valdiag.py,
7282 * support/valdiag/tests/*

7299 Bug reported from Jesus Calvino-Fraga
7301 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7303 * sdcc.spec: updated
7304 * device/include/Makefile.in: don't install CVS directories
7305 * device/lib/Makefile.in: added removal of CVS directories after install
7306 * doc/Makefile: fixed install, added local_icons
7307 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7308 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7309 * src/ds390/gen.c (genRightShift): fixed bug #870788
7310 * src/SDCCast.c (decorateType): fixed bug #870781
7312 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7314 PIC16 port related changes:
7315 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7316 added variable stackPos,
7318 * gen.c: genCall, assignResultValue: added support for
7319 pushing/retrieving function parameters to/from stack,
7320 genFunction,genEndFunction: setup stack frame for the
7322 genAddrOf: will be changed according to bug 863624
7324 * added files genutils.c and genutils.h which contain gen*
7325 debugged and optimised functions extracted from gen.c
7327 * glue.c: added variable 'externs' which holds extern symbols,
7328 pic16emitRegularMap: is modified to properly handle relocatable
7329 symbols under the new scheme,
7330 pic16createInterruptVect: is modified
7331 pic16printPublics: is modified to emit 'global' assembler directives,
7332 added pic16_printExterns to print extern symbols,
7333 pic16glue: initializes stack/frame pointer in the beginning of
7334 the assembly output. Temporary hack, will be corrected later,
7335 because gplink yet does not support stack and SDCC does not
7336 yet support a type of crt0.o object to create the final binary.
7338 * Removed many lines that contain 8051 legacy code.
7339 * The code is finally placed under a 'code' directive.
7340 * Added port specific options.
7342 * _process_pragma: simplified since now we do not need *special*
7343 include file to define SFR registers. But a separate header
7344 will be needed. This will be developed later.
7345 * _pic16_parseOptions: added, parses port specific options:
7346 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7347 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7348 --preplace-udata-with=
7350 * _pic16_setDefaultOptions: modified to initialize section names,
7351 but hack is temporarly out of order since it needs improvement.
7352 * _pic16_genAssemblerPreamble: configuration words are emitted by
7353 their address instead of their name. This part is incomplete and
7354 supports only the 18Fxx2 devices. Other devices will emit an error
7355 during assembly since they do not contain the same set of config
7357 * _pic16_genIVT: is modified,
7359 * pcode.c: added definitions for some hardware registers that are needed
7361 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7362 All PCI entries are updated. Now LFSR is supported.
7363 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7364 * added pic16_newpCodeOpLit2 to support instructions with
7365 two literal arguments
7366 * pic16_pCode2str: corrected code that emits assembler instructions
7367 with two literal operands and those that have an access bit modifier
7368 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7369 this fixes a bug which caused some labels to be lost, when an
7370 assembler directive was added, i.e. banksel,
7371 * pic16_FixRegisterBanking: improved logic that causes the insertion
7373 * InlineFunction: functions that are called once, are not any more
7374 inlined. This can be a port option in the future,
7376 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7378 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7379 hold the corresponding uninitialized symbols,
7380 * pic16_allocProcessorRegister: registers have explicit marked the
7382 * pic16_allocInternalRegister: registers are explicit marked as
7384 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7385 processing list, so bit registers were lost,
7388 * ralloc.h: added field 'accessBank' and original symbol operand
7389 in register definition,
7390 * removed the field isMapped from register definition,
7392 ** Several functions have been removed from various sources:
7393 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7394 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7395 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7396 pic16_assignRelocatableRegisters
7398 ** others have been introduced:
7399 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7400 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7402 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7404 * support/scripts/inc2h.pl: changed definition of BIT_AT
7405 to emit 'sbit at' instead of 'bit at'. This was a request.
7407 PIC16 port related preliminary changes:
7408 * gen.c: prefixed function popRegFromString with
7409 pic16_ and all references to it corrected
7410 * pcode.c: all pic16_pc_* hardware registers prefixed
7411 with underscore (_),
7412 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7413 * ralloc.c: newReg(): when register is REG_SFR then
7414 set address to rIdx,
7415 pic16_allocProcessorRegister(): marks register wasUsed=0
7416 pic16_writeUsedRegs(): added a call to assign processor
7417 registers via pic16_assignFixedRegisters
7419 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7421 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7422 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7423 variables in unused register banks. Also the SSEG is placed
7424 wherever there is enough space for it, and IDATA can be anywhere
7425 in internal RAM. For now compile using -Wl-Y[stack_size].
7426 The mem file is different for this option as well, since it
7427 makes no sense of talking about DSEG lenght.
7429 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7431 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7432 in certain cases, e.g. when ROM assignment, patch provided
7433 from Albert den Haan.
7435 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7988 not occur if the control variable is involved with a
7989 relational operator.

8478 A few small changes that speed up the peephole optimizer.
8482 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8484 Try to make the peephole optimizer smarter by maintaining
8485 an association between the assembly source code and the
8486 iCodes that originated them. Put this information to use
8487 with a new peephole rule condition "notVolatile" so that
8488 the rules can be aggressive yet still safe.
8493 * src/mcs51/peeph.def
8495 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8499 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8500 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8501 if the left or right operand symbols have the accuse flag set.
8503 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8505 Changed the type of the result of the ! (NOT) operator to char;
8506 previously it returned the same type as the source. This allows
8507 us to eliminate all the genFloatNot functions (all of its target
8508 implementations were very buggy) since !float can use the same
8511 * src/SDCCicode.c (ast2iCode): ! returns char

8520 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8521 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8522 during interrupts. Ensure WSAVE is located at a shared bank address.
8523 2. Fixed page selection in some places
8524 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8525 the registers name strings.
8526 4. Fixed "signed / unsigned compare" compiler warnings.
8527 5. The PIC port manages its own allocation of the general purpose
8528 registers, but makes no attempt to reuse them. As a result when
8529 compiling it soon runs out of general purpose registers. Some
8530 additional code was added to the files pcode.c and device.c to walk
8531 through the function call tree and rename the registers so that they
8541 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8542 genPlus() & genMinus() when the result is the same as left or right

8548 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8550 Made bitfield a distinct type from bit so that bitfields
8551 convert as per ANSI C and bits retain their traditional
8552 boolean style behaviour. Implemented bitfield support in
8560 * src/ds390/gen.c: bit v bitfield split
8561 * src/z80/gen.c: New support for bitfields
8562 * support/regression/tests/bitfields.c: reenabled z80,
8565 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8567 Rules 246.x, 247.x relate to bitfields, the others speed up
8568 access to xdata mapped I/O devices.
8570 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8572 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8574 Cleaned up genPackBits and genUnpackBits and added two helper
8575 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8576 for literal assignments in genPackBits (thanks to Frieder for
8582 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8584 Fixed bug #748310 (pointer to function type mishandled when the
8585 function name is omitted). Also fixed a SIGSEGV when a function
8586 attribute (reentrant, etc) is used on a non-function or on a
8587 function but misplaced before the parameter list.

8614 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8616 Made the constant following the "interrupt" keyword optional. If
8617 omitted, the function will not automatically be given an entry
8618 in the interrupt vector table (similar to #pragma NOIV, but
8619 less syntacticly kludgy). The interrupt number is also now
8620 range checked. Also fixed a bug in the high order bit example

8641 unsigned, but are signed by default
8642 * src/SDCCval.c (constVal): rearranged
8643 * src/SDCCval.c (valMod): preliminary fix
8644 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9089 * src/avr/avr.dsp, src/ds390/ds390.dsp, src/mcs51/mcs51.dsp,
9090 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
9091 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used

9096 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
9097 the regression tests I'm not brave enough to enable 245.b, 245.c
9098 * doc/sdccman.lyx: added latex preamble for hyperref package.
9099 Using pdflatex this will give you a hyperlinked pdf file with
9100 bookmarks. (prepend '%' before /usepackage if this breaks something)

9147 added --disable-pic16-port
9148 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9149 * src/SDCCmain.c: linkOptions is changed to set *,
9150 added if/endif conditional macros to remove options help
9151 messages from optionsTable when a port is not configured, added
9152 support for the PIc16 port in the ports table, when executing
9153 the compiler with no port specified on command line, a default
9154 port is selected with the new macro DEFAULT_PORT which is
9155 defined in port.h, in setDefaultOptions() linkOptions is removed
9156 from initialization assignment, since now it is a set,
9157 parseCmdLine uses setParseWithComma for linkOptions, in
9158 linkEdit() linkOptions are accessed with new function indexSet()
9159 which returns the i'th item of a set variable. See SDCCset.c, in
9160 linkEdit() when calling buildCmdLine(), added linkOptions as
9161 last argument. Now users can pass arguments to gplink via the
9162 -Wl option, main() uses pic16glue() to glue up pic16 programs

9174 * src/pic16/glue.c: commented out some error producing lines
9175 * src/pic16/main.c: __config directives are commented out to stop
9176 gpasm complaining and test the linkage with gplink, _linkCmd and
9177 _asmCmd changed to be more gplink and gpasm friendly
9178 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9179 produced an error when parsed, peep rule 12 is added to utilize
9180 movff, but it is commented out since the pCode does not support
9181 yet a command with 2 address arguments
9183 2003-05-18 <johan AT balder>
9185 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9210 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
9212 2003-05-11 Borut Razem <borut.razem AT siol.net>
9214 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9215 the path of bin directory, so that PATH is the only env. variable, which has to be set
9216 in case of standard installation.
9217 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

10246 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10248 * in \sdcc\as\mcs51\ changed these files in order to create an
10249 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10250 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10251 following files to include the previous two files: aslink.dsp,
10252 Makefile.aslink, Makefile.bcc, and Makefile.in.
10254 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10255 .adb instead of .cdb
10257 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10259 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10260 value from option --iram-size.
10262 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10264 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10267 2002-09-18 <wiml AT hhhh.org>
10269 * SDCClrange.h: exposed setFromRange() and setToRange()
10270 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10271 packRegsForAccUse() (bug 542397)
10272 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10273 multiple times and emitting the fetch operations more than once
10274 added aopGetUsesAcc() function to allow binary operators to
10275 fetch their operands in the correct order; made genMinus() emit
10276 compact code for X = LITERAL - Y
10278 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10279 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10280 sprintf() in line 1267.
10282 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10283 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10286 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10287 Changes to aslink (All the changes are marked with 'JCF'):
10289 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10292 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10293 area BSEG. Also moves, if possible, the DATA area down into the internal
10294 ram so more space is available.
10296 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10299 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10300 not bytes. Function summary() which creates a memory usage summary
10301 file with extension .mem. Reports of overlaping stack and small stack
10302 size. If the space for the stack is less than 16 bytes aslink trows a
10305 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10306 the 8051. Option 'y' for memory summary output file.
10308 Changes to sdcc (All the changes are marked with 'JCF'):
10310 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10312 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10313 overlaying area for it (uses RegBankUsed[4]).
10315 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10316 bank zero as used by default. By default aslink locates the stack
10317 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10318 the creation of the .mem file. Delegates the allocation of data area
10319 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10320 the begining of the stack area to aslink.
10322 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10323 glue() in SDCCglue.c creates an area for it.
10325 2002-09-03 Borut Razem <borut.razem AT siol.net>
10326 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10327 sdcc/src/pic/glue.c:
10328 introduced atexit() handler for teporay files removal in case of
10329 errors, assertions, ...
10331 2002-08-29 Borut Razem <borut.razem AT siol.net>
10332 * sdcc/support/cpp2/auto-host_vc_in.h:
10333 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10334 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10335 Maybe there is a similar problem with BORLANDC? It should be checked!
10337 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10338 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10339 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10340 was not executed, and the compiler (cl) launched a warning:
10341 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10343 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10344 * src/SDCCglue.c (printIvalArray): iterative calculation of array length

10356 - added Release configuration in VS projects
10357 - review of compiler an linker options
10358 - VC .exe files are generated in bin_vc directory, not to interfere
10359 with binaries generated from other projects (cygwin, mingw, bcc ...)
10361 * sdcc/src/yacc.dsp: added
10363 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10364 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10365 and insert the version number definitions from .version
10367 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10369 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10370 added - genarate auto-host.h using auto-host_vc_in.h as template
10373 removed from CVS, generated automatically
10375 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10376 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10378 2002-08-11 Borut Razem <borut.razem AT siol.net>
10379 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10381 2002-08-10 Borut Razem <borut.razem AT siol.net>
10382 * src/SDCCmain.c (main):
10383 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10384 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10385 The consequence was that some temporary files were not removed.
10388 unification of code in functions tempfilename() and tempfile():
10389 function tempnam() is defined in Visual Studio 6.0 and .NET
10391 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10393 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10394 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10395 - removed compiler command line option /WX: Treats all warnings as errors
10396 - update a list of source files, included into the project
10398 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10399 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10400 changed project type to Generic Project so that can be correcly converted to VS.NET project
10402 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10404 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10406 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10408 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10409 added return 0 statements after assert() to make compiler happy
10411 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10412 added newline in the def file to keep MSC compiler satisfied
10414 * sdcc/src/z80/gen.c:
10415 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10416 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10417 - solved MSC error in function aopDump()
10419 * sdcc_vc.h: define PREFIX as "\\sdcc"

10597 Previous fix was not good. basic blocks that have "break" or "return" are
10598 not really partof a loop , but live ranges used in these blocks should
