2514 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2516 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2517 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2519 One basic decision: e.g. src/clean.mk includes further files. In order
2520 to make this work there are two solutions:
2521 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2522 run configure on them. This way they can use
2523 'include $(srcdir)/port-clean.mk'
2524 - always include clean.mk by the Makefile at the same level. To avoid
2525 that `make clean` tries to include and build Makefile.dep the
2526 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2527 implemented, because now even `make uninstall` doesn't create
2528 Makefile.in. clean.mk could be eliminated by pasting it in
2531 * debugger/mcs51/Makefile.in: build own objects from library sources
2532 (SLIB, SDCC) in current directory
2534 * configure, configure.in: renamed --disable-device-lib-build in
2535 --disable-device-lib; added --enable-doc, the required tools are
2536 searched by configure; added result message; the toolchain for the
2537 belonging ports are now only built, if the port is enabled.
2539 * support/regression/*: all output is written in directory gen, because
2540 the fwk and ports directories don't livet in the build tree using vpath
2542 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2543 --disable-device-lib, added --enable-doc, added section VPATH
2545 * sim/ucsim/configure.in,
2546 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2547 z80 are enabled by default
2549 2006-04-24 Raphael Neider <rneider AT web.de>
2551 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2552 to config word, "pic14_"-prefixed some extern functions
2553 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2554 config word has been found
2555 * src/pic/device.h: added prototypes
2556 * src/pic/pcode.c: added "pic14_"-prefix where needed
2557 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
2559 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

2562 (pic14createInterruptVect): moved generating __config directives away

2572 registers that have not been assigned proper liveranges,
2573 fixes #1469504 and #1474602,
2574 (pCodeRegOptimizeRegUsage): fixed typo in comment
2576 2006-04-24 Borut Razem <borut.razem AT siol.net>
2578 * device/examples/main8051.c: deleted - it was removed from CVS
2579 24.mar.2000 and after that modified 18.feb.2001, so it reappered
2580 after the transition to Subversion
2581 * src/SDCCalloc.h: deleted - it was removed from CVS
2582 3.feb.2001 and after that modified 18.feb.2001, so it reappered

2820 implemented patch 1120823 Thanks to Willy De la Court (normal
2821 interrupts need an interrupt number now if they are made critical),
2822 and enabled nesting of critical functions though not for gbz80
2823 (genCritical, genEndCritical): added functions
2824 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
2825 * src/z80/mappings.i: added "ei" to all mappings

2837 the left operand is shorter than the result (c* = lit-c* + int),
2839 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
2842 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2844 * src/.version: increased version number to 2.5.5
2845 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
2846 linking is done manually in pic16 port's _linkEdit,
2847 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
2848 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
2849 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
2850 allocate asmop as AOP_ACC,
2851 (aopForRemat): added parameter 'bool result' in function declaration,
2852 (pic16_aopGet): return AOP_ACC when accessing WREG,
2853 (pic16_popGetTempReg): minor modification,

2864 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2865 call to allocReg, not by manually allocating a new one,
2866 (pic16_assignRegisters): now before going through the register
2867 allocating functions mark all registers as free. This eliminates some
2868 side effects resulting from peephole parser done earlier in the backbone
2870 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

2928 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
2929 which dumps before the function entry point a data byte which represents
2930 the number of the local variables used by the specified function, added
2931 'xinst' for initial support for Extended Instruction Support,
2932 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2933 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2934 port->fun_prefix anymore (may change later),
2935 (genFunction, genEndFunction): do not store/restore local registers for
2936 _main (this should take care the --main-return command line option in
2938 (genOr): removed some legacy pic-port instructions,
2939 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2940 performing operations with SFR's causes data to be written more than
2941 once to each SFR. Perhaps SFRs should be handled in special cases...
2942 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2944 * src/pic16/main.c (_process_pragma): stack bound checking did not take
2945 into account for stack starting position,

2947 --extended or -y for Extended Instruction Support,
2948 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
2949 (deassignLRs): *** perhaps the most important change, old 'for' code
2950 (commented out for reference), didn't account for some registers which
2951 were left marked 'not free' after a pointer operation. The change
2952 reduces register usage a lot in some cases
2954 2006-03-04 Borut Razem <borut.razem AT siol.net>

5231 always available in leading double underscore form. The C99 support is
5232 mostly missing, but it's a start.
5233 * support/regression/tests/bug-227710.c: fixed nonconforming use of

5314 * device/lib/printf_large.c: removed inline assembly for portability and
5315 readability. Use printf_fast if speed or size are more important.
5316 * src/pic16/gen.c: removed conditions around use of DEBUGpc
5317 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
5319 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
5321 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
5322 prevent compiler warning
5324 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
5326 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
5327 moved to level 0 and declared as static. Also they are explicit
5328 placed in access bank. This was necessery because some times they
5329 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
5330 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
5331 optimizations. Currently only compare to unsigned char is implemented,
5332 * src/pic16/gen.c: added fReturnIdx array,
5333 * (struct resolvedIfx) is moved to gen.h and made public,
5334 * (struct _G): added sregsAlloc and sregsAllocSet fields,
5335 * (aopForSym): added an optimization to directly store in stack of
5336 the operand of a SEND iCode,
5337 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
5338 but as registers instead (AOP_REG) using the fReturnIdx array,
5339 * (pic16_freeAsmop): remove the freed register from the
5340 _G.sregsAlloc field,
5341 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
5342 a compare of 'WREG',
5343 * (pic16_popGetTempRegCond): changed function prototype, now
5344 function takes also a bitVector argument v which holds the current
5345 set of registers that are allocated for stack access by aopForSym,
5346 registers allocated in aopForSym for accessing stack symbols are not
5347 any more part of the functions usedRegs field,
5348 * (genCall): some times aopOp is called for a stack variable to be
5349 send, aopForSym might perform the push, if this is true make sure
5350 that genCall doesn't push the variable twice by testing _G.resDirect,
5351 * (genFunction): changed testing for unspecified interrupt number
5352 from 256 to INTNO_UNSPEC,
5353 * modified selection scheme of frame pointer generation. Previously
5354 if function did use local registers a frame pointer was generated,
5355 now a frame pointer is generated only if function has arguments
5356 (that need PLUSW2 register access), or has stack arguments, or the
5357 compiler is not instructed to omit the frame pointer,
5358 * (genEndFunction): before restoring local registers that were saved
5359 in the function preamble, also restore the registers that *might*
5360 have been allocated for stack access,
5361 * (genRet): removed some old comments,
5362 * (genCmp, the active (RN's) version): added a call to the
5363 pic16_genCmp_special function to perform the compare with a more
5364 robust and optimized way,
5365 * (genInline): a feature has been added in inline code generation,
5366 which allows a wildcard variable substitution when writing inline
5367 assembly. Code is incomplete and experimental therefore undocumented,
5368 * (genCast): changed order of aopOp for result and right to allow
5369 aopForSym to directly load the result if possible,
5370 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
5371 perform an optimized compare on some selected special occasions,
5372 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
5373 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
5374 generate an IVT any more,
5375 * src/pic16/main.c (pic16_optionsTable): added command line option
5377 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
5378 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
5380 * src/pic16/NOTES: Raphael Neider added in list of active developers
5381 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
5382 jumptable_end to prevent bug #,
5383 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
5384 inCond and outCond fields,
5385 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
5386 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
5387 turn off register spilling,
5388 * (packRegsForOneUse): synced with other ports' versions although it
5389 is not used currently,
5390 * (pic16_packRegisters): added an optimization while reading
5391 structure bitfields, some registers may be saved (malloc code is
5392 decreased by 80 bytes)
5394 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
5396 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
5397 left is a bitfield, if yes, then don't optimize assignment. Perhaps
5398 this can be optimized more?
5400 2005-03-10 Raphael Neider <rneider AT web.de>
5402 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
5403 genNearPointerGet): (hopefully) fixed access to bitfields via
5404 pointers (p->bitN = x; and x = p->bitN; failed)
5406 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

6021 (setFromConditionArgs): friendly operand parser for peephole rules,
6022 (operandBaseName, operandsNotRelated): new peephole condition
6023 "operandsNotRelated" -- similar to "operandsNotSame", but takes
6024 architecture specific register naming into account, handles n-way

6036 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6038 Adding support for replacing ljmps with sjmps in jumptables
6039 generated for switch statements. For now you need to set the
6040 environment variable SDCC_SJMP_JUMPTABLE to enable this.
6041 Now 4 algorithms for mcs51 jumptable generation are used:
6042 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
6043 addresses loaded pc-relative for up to 112 cases and stack-pushing
6044 target addresses loaded with offset from dptr for up to 256 cases.
6046 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
6047 * src/mcs51/main.c: adapted constants for switch table generation
6048 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

6070 Large cummulative patch for pic16 port.
6071 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
6072 to call when a stack overflow occurs,
6073 * (malloc.h): added CVS Id tag,
6074 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
6076 * added libc directory. The current version of LibC contains string
6077 functions, ctype functions and macros and some functions of the
6078 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
6079 be extensively tested in the future. Standard disclaimer here.
6080 Library is not automatically build yet. But one can build it by
6081 invoking 'make' inside the libc directory.
6082 * added ADC library under libio. Preliminary version yet.
6084 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

6091 * (genUminusFloat): fixed for pic16, ported code from mcs51,
6092 * (pic16_storeForReturn): optimized return of 0,
6093 * (genCmp): experimental code for new genCmp which uses PIC18's
6094 special compare&skip instructions. Initial tests fail some times
6095 with variables grater than 1 byte in size, so new code is disabled,
6096 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
6098 * (genCast): began a fix to optimize the casting of a bit to another
6099 bit, now assigning a bitfield to another bitfield will fail, sorry,
6100 * src/pic16/main.c: disabled the use of lr-support feature,
6101 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
6102 * added some function prototypes, added function _debugf prototype,

6104 bits with offset (case PO_GPR_BIT),
6105 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
6107 * (isBankInstruction): modified to return 0 for no banking instruction,
6108 and 1 for banking instruction,
6109 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
6110 caused stop processing pCodes after a inline assembly block,
6111 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
6112 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
6113 registers when it shouldn't,
6114 * src/pic16/ralloc.c (allocReg): add preliminary support for
6115 supporting a limited set of temporary registers,
6117 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6119 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
6120 genDataPointerSet): ensure assignments always copy in MSB to LSB
6122 (loadRegFromAop): recognize CLRH optimization,
6123 (genFunction): optimize RECEIVE iCodes in reentrant functions
6125 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6127 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
6128 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
6130 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

6136 * device/lib/_gptrget.c (_gptrget),
6137 * device/lib/_gptrgetc.c (_gptrgetc),
6138 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
6139 instead of sjmp to ret
6140 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
6141 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
6143 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

9122 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
9124 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
9125 loaded with the linker search paths (-L arguments) and the libraries
9126 to be linked with the current source (-l arguments). Changes
9127 currently will affect only the pic16 port.
9128 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
9129 include path the port specific paths and port specific libraries,
9130 * gplink command now contains the $3 argument,
9131 * src/pic16/device.h,
9132 * src/pic16/device.c,: structure PIC_device is made public and
9133 renamed to PIC16_device, the same for variable Pics which is renamed
9134 to Pics16. Updated all references to them.
9135 * src/pic16/glue.c (pic16glue): corrected bug with code
9136 initialization which bypassed the variable initializations block.

9146 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
9148 Documenting changes from previous commits.
9149 * configure.in (version 1.56),
9150 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
9151 when generating output files to configure the pic16 library,
9152 but now I've commented it out, since gputils aren't installed in the
9153 SF compile farm, so library won't compile
9155 * device/lib/Makefile.in (version 1.56): initially I've added in
9156 target 'all' the prerequestive 'model-pic16' so it compiled the
9157 pic16 library, but now I've commented it out for the same reasons
9159 * added targets 'model-pic16' and 'objects-pic16' to compile the
9161 * added target 'port-specific-objects-pic16' to handle the
9162 generated libraries and copy them into the build/ directory
9163 * added target 'clean-intermediate-pic16' to clean intermediate
9164 files into pic16 directory
9165 * in target 'installdirs' added line to create directory pic16 in
9166 the installation path
9168 * device/include/Makefile.in (version 1.11): in target 'install'
9169 added lines to copy all header files to installation path,
9170 * in target 'installdirs' added line create directory for pic16
9171 headers in the installation path
9173 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

9186 * src/z80/main.c (_parseOptions): fixed the portmode= command line
9187 option so that it actually works. Made it specific to the z80, since
9188 the gbz80 doesn't have these kinds of I/O ports.
9190 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9192 * device/include/z180.h,

9201 portmode; added deprecation warning for bank= and protmode= forms.
9202 Also, guard against buffer overflow.
9203 * src/z80/gen.c (aopGet): generate better code for sfr banked read
9205 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9207 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
9208 changed interrupt vector table generation to only emit declared vectors.
9209 * device/include/Makefile.in: added missing backslash
9210 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
9212 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
9214 Mainly changes to support compilation of the device libraries
9215 * src/pic16/device.c: stack is allocated via symbol and not
9216 via literal number. The symbol is placed in the corresponding
9217 position of the data ram
9218 * (pic16_dump_section): relocatable and absolute uninitialized
9219 data are now emitted in sorted order to reduce section naming,
9220 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
9221 weren't marked as being in the access bank,
9223 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
9225 Added portion of GNU PIC Library under the directory
9226 device/include/pic16 and device/lib/pic16. These files
9227 contain the declarations of SFRs for the PIC18Fxx2 devices.
9228 The directory is initialized via configure from toplevel.
9230 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
9232 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
9233 the spilllocations to be compared correctly
9235 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
9237 * src/SDCCast.c (decorateType): fixed bug introduced today
9239 2004-01-12 Borut Razem <borut.razem AT siol.net>
9241 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

9244 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
9246 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
9247 in simpler and even better code
9249 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
9251 * src/SDCCicode.c (operandOperation): fixed bug #874819

9255 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9257 * doc/sdccman.lyx: Moved and added some sections, small changes
9258 all over. Telling LaTeX to be less strict with word spacing
9259 to better keep the right margin. Changed some notes about
9260 maintainance of the ports in section 3.2.1 - is it OK like this?
9262 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
9264 SDCC source changes:
9265 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

9298 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
9299 UPPER for immediate operands,
9300 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
9302 * src/pic16/peeph.def: all peepholes with movff are commented out,
9303 because there is a problem in the pcode peep optimizer,
9304 * src/pic16/ralloc.c: the register allocator can now reuse local
9305 function symbols for another function. This saves register usage.
9306 * src/pic16/ralloc.h: added flag isLocal in structure regs,
9308 Added file src/pic16/NOTES with information about program writing on
9309 the current port version.

9318 * src/SDCCmain.c : fixed #872250: -l command line defined library
9319 files are scanned before standard library files
9321 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9338 gen51Code): more efficient parameter receive for --model-large
9341 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9344 * src/z80/main.c: added missed needLinkerScript flags (more than
9345 one port structure defined in these file)
9346 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed
9349 2004-01-08 Vangelis Rokas <vrokas AT otenet.gr>

9362 needLinkerScript flag
9364 * src/pic16/gen.c (genAddrOf): fixed bug #863624
9365 * src/pic/glue.c: added variable udata_section_name to
9366 override default uninitialized data segment definition for
9367 devices only with SHAREBANK memory (reported from Erik Epetrich)
9368 * (pic14emitOverlay): modified to emit a commented overlay segment
9369 directive when no overlay data exist
9370 * (picglue): modified to emit uninitialized data segment
9371 according to udata_section_name
9372 * src/pic/main.c (_pic14_parseOptions): added command line

9376 arguments via -W option
9377 * src/pic16/main.c: added $l in _asmCmd, changed extension for
9378 object file from '.rel' to '.o' in port->linker structure,
9379 changed size of fptr from 2 to 3 in port structure
9381 2004-01-07 Borut Razem <borut.razem AT siol.net>
9383 * support/scripts/sdcc.nsi: update PATH
9384 * support/scripts/sdcc.ico: craeted
9386 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>
9388 * device/include/Makefile.in: fix install
9389 * doc/Makefile: fix install
9391 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9393 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
9395 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

9397 include information about variables allocated to the overlay
9400 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9402 * as/mcs51/lkmain.c: Help about -Y option

9412 LEFT_OP (left shift)
9414 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9416 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
9417 (default behaviour).
9419 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9421 A python script to validate compiler diagnostic messages. It can be
9422 used to verify that sdcc complains about bad c source code and
9423 gives a good location of the error.
9424 * support/valdiag/Makefile,
9425 * support/valdiag/valdiag.py,
9426 * support/valdiag/tests/*
9428 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9430 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
9431 * src/SDCCsymt.c (newEnumType),

9439 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9441 * src/common.h: added ifndef/define/endif macros
9442 around the header file.
9443 Bug reported from Jesus Calvino-Fraga
9445 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
9447 * sdcc.spec: updated
9448 * device/include/Makefile.in: don't install CVS directories
9449 * device/lib/Makefile.in: added removal of CVS directories after install
9450 * doc/Makefile: fixed install, added local_icons
9451 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
9452 * src/mcs51/gen.c (genRightShift): fixed bug #870788
9453 * src/ds390/gen.c (genRightShift): fixed bug #870788
9454 * src/SDCCast.c (decorateType): fixed bug #870781
9456 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9458 PIC16 port related changes:
9459 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
9460 added variable stackPos,
9462 * gen.c: genCall, assignResultValue: added support for
9463 pushing/retrieving function parameters to/from stack,
9464 genFunction,genEndFunction: setup stack frame for the
9466 genAddrOf: will be changed according to bug 863624
9468 * added files genutils.c and genutils.h which contain gen*
9469 debugged and optimised functions extracted from gen.c
9471 * glue.c: added variable 'externs' which holds extern symbols,
9472 pic16emitRegularMap: is modified to properly handle relocatable
9473 symbols under the new scheme,
9474 pic16createInterruptVect: is modified
9475 pic16printPublics: is modified to emit 'global' assembler directives,
9476 added pic16_printExterns to print extern symbols,
9477 pic16glue: initializes stack/frame pointer in the beginning of
9478 the assembly output. Temporary hack, will be corrected later,
9479 because gplink yet does not support stack and SDCC does not
9480 yet support a type of crt0.o object to create the final binary.
9482 * Removed many lines that contain 8051 legacy code.
9483 * The code is finally placed under a 'code' directive.
9484 * Added port specific options.
9486 * _process_pragma: simplified since now we do not need *special*
9487 include file to define SFR registers. But a separate header
9488 will be needed. This will be developed later.
9489 * _pic16_parseOptions: added, parses port specific options:
9490 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9491 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9492 --preplace-udata-with=
9494 * _pic16_setDefaultOptions: modified to initialize section names,
9495 but hack is temporarly out of order since it needs improvement.
9496 * _pic16_genAssemblerPreamble: configuration words are emitted by
9497 their address instead of their name. This part is incomplete and
9498 supports only the 18Fxx2 devices. Other devices will emit an error
9499 during assembly since they do not contain the same set of config
9501 * _pic16_genIVT: is modified,
9503 * pcode.c: added definitions for some hardware registers that are needed
9505 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9506 All PCI entries are updated. Now LFSR is supported.
9507 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9508 * added pic16_newpCodeOpLit2 to support instructions with
9509 two literal arguments
9510 * pic16_pCode2str: corrected code that emits assembler instructions
9511 with two literal operands and those that have an access bit modifier
9512 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9513 this fixes a bug which caused some labels to be lost, when an
9514 assembler directive was added, i.e. banksel,
9515 * pic16_FixRegisterBanking: improved logic that causes the insertion
9517 * InlineFunction: functions that are called once, are not any more
9518 inlined. This can be a port option in the future,
9520 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9522 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9523 hold the corresponding uninitialized symbols,
9524 * pic16_allocProcessorRegister: registers have explicit marked the
9526 * pic16_allocInternalRegister: registers are explicit marked as
9528 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9529 processing list, so bit registers were lost,
9532 * ralloc.h: added field 'accessBank' and original symbol operand
9533 in register definition,
9534 * removed the field isMapped from register definition,
9536 ** Several functions have been removed from various sources:
9537 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9538 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9539 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9540 pic16_assignRelocatableRegisters
9542 ** others have been introduced:
9543 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9544 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9546 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9548 * support/scripts/inc2h.pl: changed definition of BIT_AT
9549 to emit 'sbit at' instead of 'bit at'. This was a request.
9551 PIC16 port related preliminary changes:
9552 * gen.c: prefixed function popRegFromString with
9553 pic16_ and all references to it corrected
9554 * pcode.c: all pic16_pc_* hardware registers prefixed
9555 with underscore (_),
9556 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9557 * ralloc.c: newReg(): when register is REG_SFR then
9558 set address to rIdx,
9559 pic16_allocProcessorRegister(): marks register wasUsed=0
9560 pic16_writeUsedRegs(): added a call to assign processor
9561 registers via pic16_assignFixedRegisters
9563 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9565 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9566 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9567 variables in unused register banks. Also the SSEG is placed
9568 wherever there is enough space for it, and IDATA can be anywhere
9569 in internal RAM. For now compile using -Wl-Y[stack_size].
9570 The mem file is different for this option as well, since it
9571 makes no sense of talking about DSEG lenght.
9573 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9575 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9576 in certain cases, e.g. when ROM assignment, patch provided
9577 from Albert den Haan.
9579 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>
9581 Many signedness and type propagation fixes:
9582 * src/SDCCicode.c: made geniCodeCast() static
9583 replaced SPEC_ by IS_ (cosmetic)
9584 (operandOperation): fixed div and mod operation
9585 (usualBinaryConversions): added support for promotion of char
9586 (geniCodeMultiply): replaced (unsigned long) by (TYPE_UDWORD)
9587 (geniCodeDivision): replaced (unsigned long) by (TYPE_UDWORD)
9588 (geniCodeAdd): an array index will stay unsigned, even if promoted

10559 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
10561 * device/lib/_mullong.c: replaced int by short for gcc
10563 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10565 * src/SDCCpeeph.c (notVolatile, notVolatileVariable): handle IFX
10566 and JUMPTABLE iCodes properly now (worked by accident before)
10567 * src/mcs51/gen.c (leftRightUseAcc),
10568 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
10569 iCode properly now. Use getSize instead of nRegs since a & b
10570 aren't part of the nRegs tally.
10572 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
10574 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()
10575 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
10576 before instructions that use the _STATUS register
10578 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
10580 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
10581 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
10582 fetching of the pointer
10583 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
10584 copied from genNearPointerSet()
10585 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
10586 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
10587 If they pop r0/r1 they must be called in the opposite order than aopOp().
10588 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
10589 (resp. --stack-auto), prepared for --xstack
10591 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10593 * doc/sdccman.lyx: reverted tables to those in cvs 1.64
10595 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10597 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
10598 these ports have their own __sdcc_external_start()
10600 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
10602 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10603 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10604 type for bits was changed. It resulted in bit variables becoming
10605 global, which is not permitted in PIC 14 assembly output.
10607 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10609 * doc/sdccman.lyx: various additions and updates. Rearranged sections
10611 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10613 Z80 and MCS51 linkers complaint if a public symbol is defined
10614 in more than one library module:
10618 * as/mcs51/Makefile.in
10620 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10622 A few small changes that speed up the peephole optimizer.
10626 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10628 Try to make the peephole optimizer smarter by maintaining
10629 an association between the assembly source code and the
10630 iCodes that originated them. Put this information to use
10631 with a new peephole rule condition "notVolatile" so that
10632 the rules can be aggressive yet still safe.
10637 * src/mcs51/peeph.def
10639 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10643 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10644 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10645 if the left or right operand symbols have the accuse flag set.
10647 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10649 Changed the type of the result of the ! (NOT) operator to char;
10650 previously it returned the same type as the source. This allows
10651 us to eliminate all the genFloatNot functions (all of its target
10652 implementations were very buggy) since !float can use the same
10655 * src/SDCCicode.c (ast2iCode): ! returns char
10656 * src/mcs51/gen.c (genNot, genNotFloat),
10657 * src/ds390/gen.c (genNot, genNotFloat),
10658 * src/z80/gen.c (genNot, genNotFloat),
10659 * src/pic/gen.c (genNot, genNotFloat),
10660 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
10662 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
10664 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10665 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10666 during interrupts. Ensure WSAVE is located at a shared bank address.
10667 2. Fixed page selection in some places
10668 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10669 the registers name strings.
10670 4. Fixed "signed / unsigned compare" compiler warnings.
10671 5. The PIC port manages its own allocation of the general purpose
10672 registers, but makes no attempt to reuse them. As a result when
10673 compiling it soon runs out of general purpose registers. Some
10674 additional code was added to the files pcode.c and device.c to walk
10675 through the function call tree and rename the registers so that they
10685 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10686 genPlus() & genMinus() when the result is the same as left or right
10688 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10692 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10694 Made bitfield a distinct type from bit so that bitfields
10695 convert as per ANSI C and bits retain their traditional
10696 boolean style behaviour. Implemented bitfield support in
10704 * src/ds390/gen.c: bit v bitfield split
10705 * src/z80/gen.c: New support for bitfields
10706 * support/regression/tests/bitfields.c: reenabled z80,
10709 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10711 Rules 246.x, 247.x relate to bitfields, the others speed up
10712 access to xdata mapped I/O devices.
10714 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
10716 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10718 Cleaned up genPackBits and genUnpackBits and added two helper
10719 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
10720 for literal assignments in genPackBits (thanks to Frieder for
10726 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10728 Fixed bug #748310 (pointer to function type mishandled when the
10729 function name is omitted). Also fixed a SIGSEGV when a function
10730 attribute (reentrant, etc) is used on a non-function or on a
10731 function but misplaced before the parameter list.
10733 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
10735 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
10736 * support/Util/SDCCerr.h,
10737 * support/Util/SDCCerr.c: Added func attr misuse error msg
10739 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
10741 Fixed bug #787649 by anonymous
10742 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
10743 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
10745 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10747 Fixed numerous bitfield problems.
10749 * src/SDCC.y: More bitfield related error checking

10756 * support/regression/tests/bitfields.c: tests added
10758 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10760 Made the constant following the "interrupt" keyword optional. If
10761 omitted, the function will not automatically be given an entry
10762 in the interrupt vector table (similar to #pragma NOIV, but
10763 less syntacticly kludgy). The interrupt number is also now
10764 range checked. Also fixed a bug in the high order bit example
10771 * support/Util/SDCCerr.c
10772 * support/Util/SDCCerr.h

10780 * src/SDCCsymt.c (computeType): literals are handled the same way as any
10782 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
10783 be re-activated by defining REDUCE_LITERALS)
10784 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
10785 unsigned, but are signed by default
10786 * src/SDCCval.c (constVal): rearranged
10787 * src/SDCCval.c (valMod): preliminary fix
10788 * src/SDCCval.c (valCastLiteral): use TYPE_* types

10828 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
10829 * src/SDCCval.c (constVal): changed default to signed; hex and octal
10830 constants are unsigned; added recognition of "u" flag for unsigned
10831 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
10832 * src/SDCCval.c (valDiv, valMod): fixed signdness
10833 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
10834 signedness of modulo, left and right shift

11240 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
11241 the regression tests I'm not brave enough to enable 245.b, 245.c
11242 * doc/sdccman.lyx: added latex preamble for hyperref package.
11243 Using pdflatex this will give you a hyperlinked pdf file with

11293 * src/SDCCmain.c: linkOptions is changed to set *,
11294 added if/endif conditional macros to remove options help
11295 messages from optionsTable when a port is not configured, added
11296 support for the PIc16 port in the ports table, when executing
11297 the compiler with no port specified on command line, a default
11298 port is selected with the new macro DEFAULT_PORT which is
11299 defined in port.h, in setDefaultOptions() linkOptions is removed
11300 from initialization assignment, since now it is a set,
11301 parseCmdLine uses setParseWithComma for linkOptions, in
11302 linkEdit() linkOptions are accessed with new function indexSet()
11303 which returns the i'th item of a set variable. See SDCCset.c, in
11304 linkEdit() when calling buildCmdLine(), added linkOptions as
11305 last argument. Now users can pass arguments to gplink via the
11306 -Wl option, main() uses pic16glue() to glue up pic16 programs

11318 * src/pic16/glue.c: commented out some error producing lines
11319 * src/pic16/main.c: __config directives are commented out to stop
11320 gpasm complaining and test the linkage with gplink, _linkCmd and
11321 _asmCmd changed to be more gplink and gpasm friendly
11322 * src/pic16/peeph.def: peep rule 3 is commented out, since it
11323 produced an error when parsed, peep rule 12 is added to utilize
11324 movff, but it is commented out since the pCode does not support
11325 yet a command with 2 address arguments
11327 2003-05-18 <johan AT balder>
11329 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

12390 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12392 * in /sdcc/as/mcs51/ changed these files in order to create an
12393 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
12394 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
12395 following files to include the previous two files: aslink.dsp,
12396 Makefile.aslink, Makefile.bcc, and Makefile.in.
12398 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
12399 .adb instead of .cdb
12401 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12403 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
12404 value from option --iram-size.
12406 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12408 * /sdcc/as/mcs51/lklist.c: added boundary check before using
12411 2002-09-18 <wiml AT hhhh.org>
12413 * SDCClrange.h: exposed setFromRange() and setToRange()
12414 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
12415 packRegsForAccUse() (bug 542397)
12416 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
12417 multiple times and emitting the fetch operations more than once
12418 added aopGetUsesAcc() function to allow binary operators to
12419 fetch their operands in the correct order; made genMinus() emit
12420 compact code for X = LITERAL - Y
12422 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12423 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
12424 sprintf() in line 1267.
12426 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12427 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
12430 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12431 Changes to aslink (All the changes are marked with 'JCF'):
12433 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
12436 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
12437 area BSEG. Also moves, if possible, the DATA area down into the internal
12438 ram so more space is available.
12440 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
12443 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
12444 not bytes. Function summary() which creates a memory usage summary
12445 file with extension .mem. Reports of overlaping stack and small stack
12446 size. If the space for the stack is less than 16 bytes aslink trows a
12449 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
12450 the 8051. Option 'y' for memory summary output file.
12452 Changes to sdcc (All the changes are marked with 'JCF'):
12454 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
12456 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
12457 overlaying area for it (uses RegBankUsed[4]).
12459 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
12460 bank zero as used by default. By default aslink locates the stack
12461 (equivalent to --stack-after-data). Pass option 'y' to aslink for
12462 the creation of the .mem file. Delegates the allocation of data area
12463 to aslink (it is not longer 0x30 by default). If --stack-loc passes
12464 the begining of the stack area to aslink.
12466 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
12467 glue() in SDCCglue.c creates an area for it.
12469 2002-09-03 Borut Razem <borut.razem AT siol.net>
12470 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12471 sdcc/src/pic/glue.c:
12472 introduced atexit() handler for teporay files removal in case of
12473 errors, assertions, ...
12475 2002-08-29 Borut Razem <borut.razem AT siol.net>
12476 * sdcc/support/cpp2/auto-host_vc_in.h:
12477 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12478 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12479 Maybe there is a similar problem with BORLANDC? It should be checked!
12481 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12482 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12483 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12484 was not executed, and the compiler (cl) launched a warning:
12485 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12487 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12488 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
12490 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
12491 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
12493 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12494 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
12495 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
12496 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12497 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
12498 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
12499 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
12500 - added Release configuration in VS projects
12501 - review of compiler an linker options
12502 - VC .exe files are generated in bin_vc directory, not to interfere
12503 with binaries generated from other projects (cygwin, mingw, bcc ...)
12505 * sdcc/src/yacc.dsp: added
12507 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12508 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12509 and insert the version number definitions from .version
12511 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12513 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
12514 added - genarate auto-host.h using auto-host_vc_in.h as template
12517 removed from CVS, generated automatically
12519 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
12520 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12522 2002-08-11 Borut Razem <borut.razem AT siol.net>
12523 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12525 2002-08-10 Borut Razem <borut.razem AT siol.net>
12526 * src/SDCCmain.c (main):
12527 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12528 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12529 The consequence was that some temporary files were not removed.
12532 unification of code in functions tempfilename() and tempfile():
12533 function tempnam() is defined in Visual Studio 6.0 and .NET
12535 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12537 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12538 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
12539 - removed compiler command line option /WX: Treats all warnings as errors
12540 - update a list of source files, included into the project
12542 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12543 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12544 changed project type to Generic Project so that can be correcly converted to VS.NET project
12546 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12548 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
12550 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
12552 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12553 added return 0 statements after assert() to make compiler happy
12555 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12556 added newline in the def file to keep MSC compiler satisfied
12558 * sdcc/src/z80/gen.c:
12559 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
12560 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
12561 - solved MSC error in function aopDump()
12563 * sdcc_vc.h: define PREFIX as "\\sdcc"
12565 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
12566 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

12569 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
12570 - Rewrote the register banking algorithm.
12571 - Added pCode live-range analysis to registers (for now, only non-used and
12572 singly-used registers optimized away)
12574 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
12576 * 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.

12601 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
12603 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
12605 2002-03-28 Johan Knol <johan AT balder>
12607 * src/SDCCval.c: fixed bug #532436
12609 2002-03-14 Scott Dattalo <scott AT dattalo.com>
12611 Added "char *Processor" field to the port structure.
12614 Added -p option. Allows port dependent processor to be specified.
12617 Initialized the new field char *Processor field to NULL in all ports
12620 Compiler generated registers for interrupt context saving
12621 were not getting allocated.
12623 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
12626 Fixed left shift. Will promote the left side of a left shift
12627 if a) left shifting more than size of operand or b) when assigned
12628 to something size > size of left side
12630 2002-03-14 Scott Dattalo <scott AT dattalo.com>

12738 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
12740 * sdcc/src/SDCCloop.c:
12741 Previous fix was not good. basic blocks that have "break" or "return" are
12742 not really partof a loop , but live ranges used in these blocks should
12743 be live thru the entire loop, so set partOfLoop but don't add them to
12746 2002-02-21 <johan AT FRIJA>
12748 * src/SDCCcse.c: fixed bug #514308
12750 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
