1428 debug) macros to better control clutter in the generated .asm file.
1429 * src/hc08/gen.c: (forceStackedAop, genUminus, genLeftShift,
1430 genRightShift): fixed bug with non-constant bit shift stored to
1431 a volatile result (SF Open Discussion forum thread #1616749).
1432 Single byte case is not yet optimized.

3335 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
3337 Enabled VPATH feature: changed nearly all Makefiles (149 files).
3338 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
3340 One basic decision: e.g. src/clean.mk includes further files. In order
3341 to make this work there are two solutions:
3342 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
3343 run configure on them. This way they can use
3344 'include $(srcdir)/port-clean.mk'
3345 - always include clean.mk by the Makefile at the same level. To avoid
3346 that `make clean` tries to include and build Makefile.dep the
3347 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
3348 implemented, because now even `make uninstall` doesn't create
3349 Makefile.in. clean.mk could be eliminated by pasting it in
3352 * debugger/mcs51/Makefile.in: build own objects from library sources
3353 (SLIB, SDCC) in current directory
3355 * configure, configure.in: renamed --disable-device-lib-build in
3356 --disable-device-lib; added --enable-doc, the required tools are
3357 searched by configure; added result message; the toolchain for the
3358 belonging ports are now only built, if the port is enabled.
3360 * support/regression/*: all output is written in directory gen, because
3361 the fwk and ports directories don't livet in the build tree using vpath
3363 * doc/sdccman.lyx: renamed --disable-device-lib-build to
3364 --disable-device-lib, added --enable-doc, added section VPATH
3366 * sim/ucsim/configure.in,
3367 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
3368 z80 are enabled by default
3370 2006-04-24 Raphael Neider <rneider AT web.de>
3372 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
3373 to config word, "pic14_"-prefixed some extern functions
3374 (pic14_emitConfigWord): emit __config directive(s) if assignment to
3375 config word has been found
3376 * src/pic/device.h: added prototypes
3377 * src/pic/pcode.c: added "pic14_"-prefix where needed
3378 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
3380 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

3383 (pic14createInterruptVect): moved generating __config directives away
3384 (picglue): have __config directives emitted
3386 2006-04-24 Borut Razem <borut.razem AT siol.net>

3393 registers that have not been assigned proper liveranges,
3394 fixes #1469504 and #1474602,
3395 (pCodeRegOptimizeRegUsage): fixed typo in comment

3399 * device/examples/main8051.c: deleted - it was removed from CVS
3400 24.mar.2000 and after that modified 18.feb.2001, so it reappered
3401 after the transition to Subversion

3403 3.feb.2001 and after that modified 18.feb.2001, so it reappered

3641 implemented patch 1120823 Thanks to Willy De la Court (normal
3642 interrupts need an interrupt number now if they are made critical),
3643 and enabled nesting of critical functions though not for gbz80
3644 (genCritical, genEndCritical): added functions
3645 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
3646 * src/z80/mappings.i: added "ei" to all mappings

3658 the left operand is shorter than the result (c* = lit-c* + int),
3660 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
3663 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3665 * src/.version: increased version number to 2.5.5
3666 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
3667 linking is done manually in pic16 port's _linkEdit,
3668 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
3669 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
3670 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
3671 allocate asmop as AOP_ACC,
3672 (aopForRemat): added parameter 'bool result' in function declaration,
3673 (pic16_aopGet): return AOP_ACC when accessing WREG,
3674 (pic16_popGetTempReg): minor modification,

3685 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
3686 call to allocReg, not by manually allocating a new one,
3687 (pic16_assignRegisters): now before going through the register
3688 allocating functions mark all registers as free. This eliminates some
3689 side effects resulting from peephole parser done earlier in the backbone
3691 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

3749 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
3750 which dumps before the function entry point a data byte which represents
3751 the number of the local variables used by the specified function, added
3752 'xinst' for initial support for Extended Instruction Support,
3753 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
3754 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
3755 port->fun_prefix anymore (may change later),
3756 (genFunction, genEndFunction): do not store/restore local registers for
3757 _main (this should take care the --main-return command line option in
3759 (genOr): removed some legacy pic-port instructions,
3760 * src/pic16/genarith.c (genAddLit): re-enabled old code because
3761 performing operations with SFR's causes data to be written more than
3762 once to each SFR. Perhaps SFRs should be handled in special cases...
3763 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
3765 * src/pic16/main.c (_process_pragma): stack bound checking did not take
3766 into account for stack starting position,

3768 --extended or -y for Extended Instruction Support,
3769 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
3770 (deassignLRs): *** perhaps the most important change, old 'for' code
3771 (commented out for reference), didn't account for some registers which
3772 were left marked 'not free' after a pointer operation. The change
3773 reduces register usage a lot in some cases
3775 2006-03-04 Borut Razem <borut.razem AT siol.net>

6048 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
6049 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
6050 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
6051 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
6052 always available in leading double underscore form. The C99 support is
6053 mostly missing, but it's a start.
6054 * support/regression/tests/bug-227710.c: fixed nonconforming use of
6055 reserved identifier "__data".
6057 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

6133 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
6135 * device/lib/printf_large.c: removed inline assembly for portability and
6136 readability. Use printf_fast if speed or size are more important.
6137 * src/pic16/gen.c: removed conditions around use of DEBUGpc
6138 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
6140 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
6142 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
6143 prevent compiler warning
6145 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
6147 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
6148 moved to level 0 and declared as static. Also they are explicit
6149 placed in access bank. This was necessery because some times they
6150 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
6151 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
6152 optimizations. Currently only compare to unsigned char is implemented,
6153 * src/pic16/gen.c: added fReturnIdx array,
6154 * (struct resolvedIfx) is moved to gen.h and made public,
6155 * (struct _G): added sregsAlloc and sregsAllocSet fields,
6156 * (aopForSym): added an optimization to directly store in stack of
6157 the operand of a SEND iCode,
6158 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
6159 but as registers instead (AOP_REG) using the fReturnIdx array,
6160 * (pic16_freeAsmop): remove the freed register from the
6161 _G.sregsAlloc field,
6162 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
6163 a compare of 'WREG',
6164 * (pic16_popGetTempRegCond): changed function prototype, now
6165 function takes also a bitVector argument v which holds the current
6166 set of registers that are allocated for stack access by aopForSym,
6167 registers allocated in aopForSym for accessing stack symbols are not
6168 any more part of the functions usedRegs field,
6169 * (genCall): some times aopOp is called for a stack variable to be
6170 send, aopForSym might perform the push, if this is true make sure
6171 that genCall doesn't push the variable twice by testing _G.resDirect,
6172 * (genFunction): changed testing for unspecified interrupt number
6173 from 256 to INTNO_UNSPEC,
6174 * modified selection scheme of frame pointer generation. Previously
6175 if function did use local registers a frame pointer was generated,
6176 now a frame pointer is generated only if function has arguments
6177 (that need PLUSW2 register access), or has stack arguments, or the
6178 compiler is not instructed to omit the frame pointer,
6179 * (genEndFunction): before restoring local registers that were saved
6180 in the function preamble, also restore the registers that *might*
6181 have been allocated for stack access,
6182 * (genRet): removed some old comments,
6183 * (genCmp, the active (RN's) version): added a call to the
6184 pic16_genCmp_special function to perform the compare with a more
6185 robust and optimized way,
6186 * (genInline): a feature has been added in inline code generation,
6187 which allows a wildcard variable substitution when writing inline
6188 assembly. Code is incomplete and experimental therefore undocumented,
6189 * (genCast): changed order of aopOp for result and right to allow
6190 aopForSym to directly load the result if possible,
6191 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
6192 perform an optimized compare on some selected special occasions,
6193 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
6194 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
6195 generate an IVT any more,
6196 * src/pic16/main.c (pic16_optionsTable): added command line option
6198 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
6199 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
6201 * src/pic16/NOTES: Raphael Neider added in list of active developers
6202 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
6203 jumptable_end to prevent bug #,
6204 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
6205 inCond and outCond fields,
6206 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
6207 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
6208 turn off register spilling,
6209 * (packRegsForOneUse): synced with other ports' versions although it
6210 is not used currently,
6211 * (pic16_packRegisters): added an optimization while reading
6212 structure bitfields, some registers may be saved (malloc code is
6213 decreased by 80 bytes)
6215 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
6217 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
6218 left is a bitfield, if yes, then don't optimize assignment. Perhaps
6219 this can be optimized more?
6221 2005-03-10 Raphael Neider <rneider AT web.de>
6223 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
6224 genNearPointerGet): (hopefully) fixed access to bitfields via
6225 pointers (p->bitN = x; and x = p->bitN; failed)
6227 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
6229 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

6404 * src/pic16/main.c (_process_pragma): fixed another malloc bug
6405 (sizeof(sectNames) changed to sizeof(sectName))
6406 Both patches fix segfaults under MinGW.

6412 * src/pic16/gen.c (pic16_aopOp,pic16_popGet): added handling
6413 of (byte sized) temporaries (assign them to WREG for now)
6414 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
6415 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
6416 this might fix SIGSEGVs on MinGW...
6417 * src/SDCCopt.c (killDeadCode): restored original behaviour
6418 (volatile operands might get thrown away though)
6420 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
6422 * src/pic16/gen.c: fixed bug #1106975,

6881 2004-11-25 Vangelis Rokas <vrokas AT otenet.gr>
6883 * src/pic16/device.h,
6884 * src/pic16/genarith.c,
6887 * src/pic16/pcode.c: applied patches #1068154 and #1070213
6889 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
6891 Large cummulative patch for pic16 port.
6892 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
6893 to call when a stack overflow occurs,
6894 * (malloc.h): added CVS Id tag,
6895 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
6897 * added libc directory. The current version of LibC contains string
6898 functions, ctype functions and macros and some functions of the
6899 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
6900 be extensively tested in the future. Standard disclaimer here.
6901 Library is not automatically build yet. But one can build it by
6902 invoking 'make' inside the libc directory.
6903 * added ADC library under libio. Preliminary version yet.
6905 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
6906 * src/pic16/gen.c (aopForRemat): asmop size is filled by
6907 aopForRemat() now and not by pic16_aopOp(),
6908 * (pic16_popGetTempReg): removed warning messgae when allocating
6909 temporary registers, its a buggy feature and will be removed,
6910 * (pic16_popGet): set register instance field in AOP_CRY,
6911 * (pic16_outBitC): fixed for results in size greater than 1,
6912 * (genUminusFloat): fixed for pic16, ported code from mcs51,
6913 * (pic16_storeForReturn): optimized return of 0,
6914 * (genCmp): experimental code for new genCmp which uses PIC18's
6915 special compare&skip instructions. Initial tests fail some times
6916 with variables grater than 1 byte in size, so new code is disabled,
6917 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
6919 * (genCast): began a fix to optimize the casting of a bit to another
6920 bit, now assigning a bitfield to another bitfield will fail, sorry,
6921 * src/pic16/main.c: disabled the use of lr-support feature,
6922 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
6923 * added some function prototypes, added function _debugf prototype,
6924 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
6925 bits with offset (case PO_GPR_BIT),
6926 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
6928 * (isBankInstruction): modified to return 0 for no banking instruction,
6929 and 1 for banking instruction,
6930 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
6931 caused stop processing pCodes after a inline assembly block,
6932 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
6933 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
6934 registers when it shouldn't,
6935 * src/pic16/ralloc.c (allocReg): add preliminary support for
6936 supporting a limited set of temporary registers,
6938 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6940 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
6941 genDataPointerSet): ensure assignments always copy in MSB to LSB
6943 (loadRegFromAop): recognize CLRH optimization,
6944 (genFunction): optimize RECEIVE iCodes in reentrant functions
6946 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6948 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
6949 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
6951 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

9943 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
9945 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
9946 loaded with the linker search paths (-L arguments) and the libraries
9947 to be linked with the current source (-l arguments). Changes
9948 currently will affect only the pic16 port.
9949 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
9950 include path the port specific paths and port specific libraries,
9951 * gplink command now contains the $3 argument,
9952 * src/pic16/device.h,
9953 * src/pic16/device.c,: structure PIC_device is made public and
9954 renamed to PIC16_device, the same for variable Pics which is renamed

9969 Documenting changes from previous commits.
9970 * configure.in (version 1.56),
9971 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
9972 when generating output files to configure the pic16 library,
9973 but now I've commented it out, since gputils aren't installed in the
9974 SF compile farm, so library won't compile
9976 * device/lib/Makefile.in (version 1.56): initially I've added in
9977 target 'all' the prerequestive 'model-pic16' so it compiled the
9978 pic16 library, but now I've commented it out for the same reasons
9980 * added targets 'model-pic16' and 'objects-pic16' to compile the
9982 * added target 'port-specific-objects-pic16' to handle the
9983 generated libraries and copy them into the build/ directory
9984 * added target 'clean-intermediate-pic16' to clean intermediate
9985 files into pic16 directory
9986 * in target 'installdirs' added line to create directory pic16 in
9987 the installation path

9990 added lines to copy all header files to installation path,
9991 * in target 'installdirs' added line create directory for pic16
9992 headers in the installation path

10005 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10007 * src/z80/main.c (_parseOptions): fixed the portmode= command line
10008 option so that it actually works. Made it specific to the z80, since
10009 the gbz80 doesn't have these kinds of I/O ports.
10011 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10013 * device/include/z180.h,

10035 Mainly changes to support compilation of the device libraries
10036 * src/pic16/device.c: stack is allocated via symbol and not
10037 via literal number. The symbol is placed in the corresponding
10038 position of the data ram
10039 * (pic16_dump_section): relocatable and absolute uninitialized
10040 data are now emitted in sorted order to reduce section naming,
10041 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
10042 weren't marked as being in the access bank,
10044 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
10046 Added portion of GNU PIC Library under the directory
10047 device/include/pic16 and device/lib/pic16. These files
10048 contain the declarations of SFRs for the PIC18Fxx2 devices.
10049 The directory is initialized via configure from toplevel.
10051 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
10053 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
10054 the spilllocations to be compared correctly
10056 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
10058 * src/SDCCast.c (decorateType): fixed bug introduced today
10060 2004-01-12 Borut Razem <borut.razem AT siol.net>

10078 * doc/sdccman.lyx: Moved and added some sections, small changes
10079 all over. Telling LaTeX to be less strict with word spacing
10080 to better keep the right margin. Changed some notes about
10081 maintainance of the ports in section 3.2.1 - is it OK like this?
10083 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
10085 SDCC source changes:
10086 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,
10087 convilong): modified to inform the pic16 port that builtin functions
10090 PIC16 PORT specific changes:
10091 * src/pic16/device.c pic16_dump_equates() added,

10120 UPPER for immediate operands,
10121 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
10123 * src/pic16/peeph.def: all peepholes with movff are commented out,
10124 because there is a problem in the pcode peep optimizer,
10125 * src/pic16/ralloc.c: the register allocator can now reuse local
10126 function symbols for another function. This saves register usage.
10127 * src/pic16/ralloc.h: added flag isLocal in structure regs,
10129 Added file src/pic16/NOTES with information about program writing on
10130 the current port version.
10132 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10134 * src/mcs51/peephole.def: added peepholes 177.c,d (redundant moves)
10135 and peephole 252 (array access)
10137 2004-01-09 Borut Razem <borut.razem AT siol.net>
10139 * src/SDCCmain.c : fixed #872250: -l command line defined library

10154 * sdcc.spec: fixed typo
10156 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10158 * src/mcs51/gen.c (genFunction, genEndFunction, genReceive, getTempRegs,
10159 gen51Code): more efficient parameter receive for --model-large
10162 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10164 * src/ds390/main.c,
10165 * src/z80/main.c: added missed needLinkerScript flags (more than
10166 one port structure defined in these file)
10167 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed
10170 2004-01-08 Vangelis Rokas <vrokas AT otenet.gr>

10188 devices only with SHAREBANK memory (reported from Erik Epetrich)
10189 * (pic14emitOverlay): modified to emit a commented overlay segment
10190 directive when no overlay data exist
10191 * (picglue): modified to emit uninitialized data segment
10192 according to udata_section_name
10193 * src/pic/main.c (_pic14_parseOptions): added command line
10194 options --udata-section-name=[name] to override default
10195 udata definition name
10196 * modified _linkCmd and _asmCmd to include compiler passed
10197 arguments via -W option
10198 * src/pic16/main.c: added $l in _asmCmd, changed extension for

10204 * support/scripts/sdcc.nsi: update PATH
10205 * support/scripts/sdcc.ico: craeted
10207 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>

10210 * doc/Makefile: fix install
10212 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10214 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
10216 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to
10217 how the function variable allocation summary is displayed; also
10218 include information about variables allocated to the overlay
10221 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10223 * as/mcs51/lkmain.c: Help about -Y option
10224 * as/mcs51/lkarea.c: Fixed gcc warnings
10226 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
10228 * src/SDCCval.c (valShift): changed from 16 to 32 bit shift count,

10235 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10237 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
10238 (default behaviour).
10240 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10242 A python script to validate compiler diagnostic messages. It can be
10243 used to verify that sdcc complains about bad c source code and
10244 gives a good location of the error.
10245 * support/valdiag/Makefile,
10246 * support/valdiag/valdiag.py,
10247 * support/valdiag/tests/*
10249 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10251 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
10252 * src/SDCCsymt.c (newEnumType),
10254 * support/Util/SDCCerr.c,

10260 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
10262 * src/common.h: added ifndef/define/endif macros
10263 around the header file.
10264 Bug reported from Jesus Calvino-Fraga
10266 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
10268 * sdcc.spec: updated
10269 * device/include/Makefile.in: don't install CVS directories

10274 * src/ds390/gen.c (genRightShift): fixed bug #870788
10275 * src/SDCCast.c (decorateType): fixed bug #870781
10277 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
10279 PIC16 port related changes:
10280 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
10281 added variable stackPos,
10283 * gen.c: genCall, assignResultValue: added support for
10284 pushing/retrieving function parameters to/from stack,
10285 genFunction,genEndFunction: setup stack frame for the
10286 generated function,
10287 genAddrOf: will be changed according to bug 863624
10289 * added files genutils.c and genutils.h which contain gen*
10290 debugged and optimised functions extracted from gen.c
10292 * glue.c: added variable 'externs' which holds extern symbols,
10293 pic16emitRegularMap: is modified to properly handle relocatable
10294 symbols under the new scheme,
10295 pic16createInterruptVect: is modified
10296 pic16printPublics: is modified to emit 'global' assembler directives,
10297 added pic16_printExterns to print extern symbols,
10298 pic16glue: initializes stack/frame pointer in the beginning of
10299 the assembly output. Temporary hack, will be corrected later,
10300 because gplink yet does not support stack and SDCC does not
10301 yet support a type of crt0.o object to create the final binary.
10303 * Removed many lines that contain 8051 legacy code.
10304 * The code is finally placed under a 'code' directive.
10305 * Added port specific options.
10307 * _process_pragma: simplified since now we do not need *special*
10308 include file to define SFR registers. But a separate header
10309 will be needed. This will be developed later.
10310 * _pic16_parseOptions: added, parses port specific options:
10311 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
10312 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
10313 --preplace-udata-with=
10315 * _pic16_setDefaultOptions: modified to initialize section names,
10316 but hack is temporarly out of order since it needs improvement.
10317 * _pic16_genAssemblerPreamble: configuration words are emitted by
10318 their address instead of their name. This part is incomplete and
10319 supports only the 18Fxx2 devices. Other devices will emit an error
10320 during assembly since they do not contain the same set of config
10322 * _pic16_genIVT: is modified,
10324 * pcode.c: added definitions for some hardware registers that are needed
10326 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
10327 All PCI entries are updated. Now LFSR is supported.
10328 * Removed pic16_pciTRIS is mentioned by mdubuc in source
10329 * added pic16_newpCodeOpLit2 to support instructions with
10330 two literal arguments
10331 * pic16_pCode2str: corrected code that emits assembler instructions
10332 with two literal operands and those that have an access bit modifier
10333 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
10334 this fixes a bug which caused some labels to be lost, when an
10335 assembler directive was added, i.e. banksel,
10336 * pic16_FixRegisterBanking: improved logic that causes the insertion
10338 * InlineFunction: functions that are called once, are not any more
10339 inlined. This can be a port option in the future,
10341 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
10343 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
10344 hold the corresponding uninitialized symbols,
10345 * pic16_allocProcessorRegister: registers have explicit marked the
10347 * pic16_allocInternalRegister: registers are explicit marked as
10349 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
10350 processing list, so bit registers were lost,
10353 * ralloc.h: added field 'accessBank' and original symbol operand
10354 in register definition,
10355 * removed the field isMapped from register definition,
10357 ** Several functions have been removed from various sources:
10358 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
10359 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
10360 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
10361 pic16_assignRelocatableRegisters
10363 ** others have been introduced:
10364 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
10365 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
10367 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
10369 * support/scripts/inc2h.pl: changed definition of BIT_AT
10370 to emit 'sbit at' instead of 'bit at'. This was a request.
10372 PIC16 port related preliminary changes:
10373 * gen.c: prefixed function popRegFromString with
10374 pic16_ and all references to it corrected
10375 * pcode.c: all pic16_pc_* hardware registers prefixed
10376 with underscore (_),
10377 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
10378 * ralloc.c: newReg(): when register is REG_SFR then
10379 set address to rIdx,
10380 pic16_allocProcessorRegister(): marks register wasUsed=0
10381 pic16_writeUsedRegs(): added a call to assign processor
10382 registers via pic16_assignFixedRegisters
10384 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10386 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
10387 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
10388 variables in unused register banks. Also the SSEG is placed
10389 wherever there is enough space for it, and IDATA can be anywhere
10390 in internal RAM. For now compile using -Wl-Y[stack_size].
10391 The mem file is different for this option as well, since it
10392 makes no sense of talking about DSEG lenght.
10394 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
10396 * src/SDCClrange.c: fixed bug 869095 that caused segfault
10397 in certain cases, e.g. when ROM assignment, patch provided
10398 from Albert den Haan.
10400 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

11390 iCode properly now. Use getSize instead of nRegs since a & b
11391 aren't part of the nRegs tally.
11393 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
11395 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()
11396 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
11397 before instructions that use the _STATUS register
11399 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
11401 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
11402 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
11403 fetching of the pointer
11404 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
11405 copied from genNearPointerSet()
11406 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
11407 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
11408 If they pop r0/r1 they must be called in the opposite order than aopOp().
11409 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
11410 (resp. --stack-auto), prepared for --xstack
11412 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11414 * doc/sdccman.lyx: reverted tables to those in cvs 1.64
11416 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11418 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
11419 these ports have their own __sdcc_external_start()
11421 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
11423 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11424 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
11425 type for bits was changed. It resulted in bit variables becoming
11426 global, which is not permitted in PIC 14 assembly output.
11428 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11430 * doc/sdccman.lyx: various additions and updates. Rearranged sections
11432 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11434 Z80 and MCS51 linkers complaint if a public symbol is defined
11435 in more than one library module:
11439 * as/mcs51/Makefile.in
11441 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11443 A few small changes that speed up the peephole optimizer.
11447 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11449 Try to make the peephole optimizer smarter by maintaining
11450 an association between the assembly source code and the
11451 iCodes that originated them. Put this information to use
11452 with a new peephole rule condition "notVolatile" so that
11453 the rules can be aggressive yet still safe.
11458 * src/mcs51/peeph.def
11460 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11464 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
11465 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
11466 if the left or right operand symbols have the accuse flag set.
11468 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11470 Changed the type of the result of the ! (NOT) operator to char;
11471 previously it returned the same type as the source. This allows
11472 us to eliminate all the genFloatNot functions (all of its target
11473 implementations were very buggy) since !float can use the same
11476 * src/SDCCicode.c (ast2iCode): ! returns char
11477 * src/mcs51/gen.c (genNot, genNotFloat),
11478 * src/ds390/gen.c (genNot, genNotFloat),
11479 * src/z80/gen.c (genNot, genNotFloat),
11480 * src/pic/gen.c (genNot, genNotFloat),
11481 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

11485 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11486 1. Interrupt would not compile properly. Ensure PCLATH register is saved
11487 during interrupts. Ensure WSAVE is located at a shared bank address.
11488 2. Fixed page selection in some places
11489 3. Fixed BTFSS/C to where necessary use registers directly and not simply
11490 the registers name strings.
11491 4. Fixed "signed / unsigned compare" compiler warnings.
11492 5. The PIC port manages its own allocation of the general purpose
11493 registers, but makes no attempt to reuse them. As a result when
11494 compiling it soon runs out of general purpose registers. Some
11495 additional code was added to the files pcode.c and device.c to walk
11496 through the function call tree and rename the registers so that they
11506 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
11507 genPlus() & genMinus() when the result is the same as left or right
11509 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

11513 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11515 Made bitfield a distinct type from bit so that bitfields
11516 convert as per ANSI C and bits retain their traditional
11517 boolean style behaviour. Implemented bitfield support in
11525 * src/ds390/gen.c: bit v bitfield split
11526 * src/z80/gen.c: New support for bitfields
11527 * support/regression/tests/bitfields.c: reenabled z80,
11530 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11532 Rules 246.x, 247.x relate to bitfields, the others speed up
11533 access to xdata mapped I/O devices.
11535 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
11537 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11539 Cleaned up genPackBits and genUnpackBits and added two helper
11540 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
11541 for literal assignments in genPackBits (thanks to Frieder for
11547 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11549 Fixed bug #748310 (pointer to function type mishandled when the
11550 function name is omitted). Also fixed a SIGSEGV when a function
11551 attribute (reentrant, etc) is used on a non-function or on a
11552 function but misplaced before the parameter list.
11554 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
11556 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
11557 * support/Util/SDCCerr.h,
11558 * support/Util/SDCCerr.c: Added func attr misuse error msg
11560 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
11562 Fixed bug #787649 by anonymous
11563 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
11564 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
11566 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11568 Fixed numerous bitfield problems.
11570 * src/SDCC.y: More bitfield related error checking

11579 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11581 Made the constant following the "interrupt" keyword optional. If
11582 omitted, the function will not automatically be given an entry
11583 in the interrupt vector table (similar to #pragma NOIV, but
11584 less syntacticly kludgy). The interrupt number is also now
11585 range checked. Also fixed a bug in the high order bit example
11592 * support/Util/SDCCerr.c
11593 * support/Util/SDCCerr.h
11596 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

11601 * src/SDCCsymt.c (computeType): literals are handled the same way as any
11603 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
11604 be re-activated by defining REDUCE_LITERALS)
11605 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
11606 unsigned, but are signed by default
11607 * src/SDCCval.c (constVal): rearranged
11608 * src/SDCCval.c (valMod): preliminary fix
11609 * src/SDCCval.c (valCastLiteral): use TYPE_* types

11649 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
11650 * src/SDCCval.c (constVal): changed default to signed; hex and octal
11651 constants are unsigned; added recognition of "u" flag for unsigned
11652 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
11653 * src/SDCCval.c (valDiv, valMod): fixed signdness

12061 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
12062 the regression tests I'm not brave enough to enable 245.b, 245.c
12063 * doc/sdccman.lyx: added latex preamble for hyperref package.
12064 Using pdflatex this will give you a hyperlinked pdf file with
12065 bookmarks. (prepend '%' before /usepackage if this breaks something)

12115 added if/endif conditional macros to remove options help
12116 messages from optionsTable when a port is not configured, added
12117 support for the PIc16 port in the ports table, when executing
12118 the compiler with no port specified on command line, a default
12119 port is selected with the new macro DEFAULT_PORT which is
12120 defined in port.h, in setDefaultOptions() linkOptions is removed
12121 from initialization assignment, since now it is a set,
12122 parseCmdLine uses setParseWithComma for linkOptions, in
12123 linkEdit() linkOptions are accessed with new function indexSet()
12124 which returns the i'th item of a set variable. See SDCCset.c, in
12125 linkEdit() when calling buildCmdLine(), added linkOptions as
12126 last argument. Now users can pass arguments to gplink via the
12127 -Wl option, main() uses pic16glue() to glue up pic16 programs

12139 * src/pic16/glue.c: commented out some error producing lines
12140 * src/pic16/main.c: __config directives are commented out to stop
12141 gpasm complaining and test the linkage with gplink, _linkCmd and
12142 _asmCmd changed to be more gplink and gpasm friendly
12143 * src/pic16/peeph.def: peep rule 3 is commented out, since it
12144 produced an error when parsed, peep rule 12 is added to utilize
12145 movff, but it is commented out since the pCode does not support
12146 yet a command with 2 address arguments
12148 2003-05-18 <johan AT balder>
12150 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

13217 Makefile.aslink, Makefile.bcc, and Makefile.in.
13219 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
13220 .adb instead of .cdb
13222 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13224 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
13225 value from option --iram-size.
13227 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13229 * /sdcc/as/mcs51/lklist.c: added boundary check before using
13232 2002-09-18 <wiml AT hhhh.org>
13234 * SDCClrange.h: exposed setFromRange() and setToRange()
13235 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
13236 packRegsForAccUse() (bug 542397)
13237 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
13238 multiple times and emitting the fetch operations more than once
13239 added aopGetUsesAcc() function to allow binary operators to
13240 fetch their operands in the correct order; made genMinus() emit
13241 compact code for X = LITERAL - Y
13243 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13244 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
13245 sprintf() in line 1267.
13247 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13248 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
13251 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13252 Changes to aslink (All the changes are marked with 'JCF'):
13254 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
13257 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
13258 area BSEG. Also moves, if possible, the DATA area down into the internal
13259 ram so more space is available.
13261 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
13264 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
13265 not bytes. Function summary() which creates a memory usage summary
13266 file with extension .mem. Reports of overlaping stack and small stack
13267 size. If the space for the stack is less than 16 bytes aslink trows a
13270 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
13271 the 8051. Option 'y' for memory summary output file.
13273 Changes to sdcc (All the changes are marked with 'JCF'):
13275 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
13277 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
13278 overlaying area for it (uses RegBankUsed[4]).
13280 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
13281 bank zero as used by default. By default aslink locates the stack
13282 (equivalent to --stack-after-data). Pass option 'y' to aslink for
13283 the creation of the .mem file. Delegates the allocation of data area
13284 to aslink (it is not longer 0x30 by default). If --stack-loc passes
13285 the begining of the stack area to aslink.
13287 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
13288 glue() in SDCCglue.c creates an area for it.
13290 2002-09-03 Borut Razem <borut.razem AT siol.net>
13291 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
13292 sdcc/src/pic/glue.c:
13293 introduced atexit() handler for teporay files removal in case of
13294 errors, assertions, ...
13296 2002-08-29 Borut Razem <borut.razem AT siol.net>
13297 * sdcc/support/cpp2/auto-host_vc_in.h:
13298 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
13299 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
13300 Maybe there is a similar problem with BORLANDC? It should be checked!
13302 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
13303 corrected improper use of assert: the assignment to clr variable was done inside the assert.
13304 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
13305 was not executed, and the compiler (cl) launched a warning:
13306 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
13308 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
13309 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
13311 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
13312 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
13314 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
13315 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
13316 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
13317 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
13318 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
13319 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
13320 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
13321 - added Release configuration in VS projects
13322 - review of compiler an linker options
13323 - VC .exe files are generated in bin_vc directory, not to interfere
13324 with binaries generated from other projects (cygwin, mingw, bcc ...)
13326 * sdcc/src/yacc.dsp: added
13328 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
13329 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
13330 and insert the version number definitions from .version
13332 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
13334 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
13335 added - genarate auto-host.h using auto-host_vc_in.h as template
13338 removed from CVS, generated automatically
13340 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
13341 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
13343 2002-08-11 Borut Razem <borut.razem AT siol.net>
13344 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
13346 2002-08-10 Borut Razem <borut.razem AT siol.net>
13347 * src/SDCCmain.c (main):
13348 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
13349 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
13350 The consequence was that some temporary files were not removed.
13353 unification of code in functions tempfilename() and tempfile():
13354 function tempnam() is defined in Visual Studio 6.0 and .NET
13356 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
13358 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
13359 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
13360 - removed compiler command line option /WX: Treats all warnings as errors
13361 - update a list of source files, included into the project
13363 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
13364 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
13365 changed project type to Generic Project so that can be correcly converted to VS.NET project
13367 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
13369 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
13371 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
13373 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
13374 added return 0 statements after assert() to make compiler happy
13376 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
13377 added newline in the def file to keep MSC compiler satisfied
13379 * sdcc/src/z80/gen.c:
13380 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
13381 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
13382 - solved MSC error in function aopDump()
13384 * sdcc_vc.h: define PREFIX as "\\sdcc"
13386 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
13387 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

13390 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
13391 - Rewrote the register banking algorithm.
13392 - Added pCode live-range analysis to registers (for now, only non-used and
13393 singly-used registers optimized away)
13395 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
13397 * support/scripts/inc2h.pl Kevin L. Pauba <klpauba AT cox.net> submitted this perl script for converting MicroChip include files into SDCC Pic include files.

13422 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
13424 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
13426 2002-03-28 Johan Knol <johan AT balder>
13428 * src/SDCCval.c: fixed bug #532436
13430 2002-03-14 Scott Dattalo <scott AT dattalo.com>
13432 Added "char *Processor" field to the port structure.
13435 Added -p option. Allows port dependent processor to be specified.
13438 Initialized the new field char *Processor field to NULL in all ports
13441 Compiler generated registers for interrupt context saving
13442 were not getting allocated.
13444 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
13447 Fixed left shift. Will promote the left side of a left shift
13448 if a) left shifting more than size of operand or b) when assigned
13449 to something size > size of left side
13451 2002-03-14 Scott Dattalo <scott AT dattalo.com>

13455 analysis is restructured. ...
13457 * src/pic/device.h:
13460 * src/pic/device.c:
13461 Added. device.c is a PIC port hack to accomodate variations
13464 2002-03-13 Michael Hope <michaelh AT vroom>
13466 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
13468 2002-03-04 johanknol <johanknol AT manik>
13470 * /src/SDCCval.c: fixed
13472 const unsigned char arr[][2] = { { 0, 1 } };

13559 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
13561 * sdcc/src/SDCCloop.c:
13562 Previous fix was not good. basic blocks that have "break" or "return" are
13563 not really partof a loop , but live ranges used in these blocks should
13564 be live thru the entire loop, so set partOfLoop but don't add them to
13567 2002-02-21 <johan AT FRIJA>
13569 * src/SDCCcse.c: fixed bug #514308
13571 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
13574 Fixed BUG #519583. If a conditional block ended in a return/break
13575 statement inside a loop, it was not being considered part of the loop.
13577 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
13579 2002-02-10 Karl Bongers <karl AT turbobit.com>
