2475 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2477 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2478 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2480 One basic decision: e.g. src/clean.mk includes further files. In order
2481 to make this work there are two solutions:
2482 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2483 run configure on them. This way they can use
2484 'include $(srcdir)/port-clean.mk'
2485 - always include clean.mk by the Makefile at the same level. To avoid
2486 that `make clean` tries to include and build Makefile.dep the
2487 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2488 implemented, because now even `make uninstall` doesn't create
2489 Makefile.in. clean.mk could be eliminated by pasting it in
2492 * debugger/mcs51/Makefile.in: build own objects from library sources
2493 (SLIB, SDCC) in current directory
2495 * configure, configure.in: renamed --disable-device-lib-build in
2496 --disable-device-lib; added --enable-doc, the required tools are
2497 searched by configure; added result message; the toolchain for the
2498 belonging ports are now only built, if the port is enabled.
2500 * support/regression/*: all output is written in directory gen, because
2501 the fwk and ports directories don't livet in the build tree using vpath
2503 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2504 --disable-device-lib, added --enable-doc, added section VPATH
2506 * sim/ucsim/configure.in,
2507 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2508 z80 are enabled by default
2510 2006-04-24 Raphael Neider <rneider AT web.de>
2512 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2513 to config word, "pic14_"-prefixed some extern functions
2514 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2515 config word has been found
2516 * src/pic/device.h: added prototypes
2517 * src/pic/pcode.c: added "pic14_"-prefix where needed
2518 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
2520 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

2523 (pic14createInterruptVect): moved generating __config directives away

2533 registers that have not been assigned proper liveranges,
2534 fixes #1469504 and #1474602,
2535 (pCodeRegOptimizeRegUsage): fixed typo in comment
2537 2006-04-24 Borut Razem <borut.razem AT siol.net>
2539 * device/examples/main8051.c: deleted - it was removed from CVS
2540 24.mar.2000 and after that modified 18.feb.2001, so it reappered
2541 after the transition to Subversion
2542 * src/SDCCalloc.h: deleted - it was removed from CVS
2543 3.feb.2001 and after that modified 18.feb.2001, so it reappered

2781 implemented patch 1120823 Thanks to Willy De la Court (normal
2782 interrupts need an interrupt number now if they are made critical),
2783 and enabled nesting of critical functions though not for gbz80
2784 (genCritical, genEndCritical): added functions
2785 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
2786 * src/z80/mappings.i: added "ei" to all mappings

2798 the left operand is shorter than the result (c* = lit-c* + int),
2800 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
2803 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2805 * src/.version: increased version number to 2.5.5
2806 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
2807 linking is done manually in pic16 port's _linkEdit,
2808 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
2809 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
2810 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
2811 allocate asmop as AOP_ACC,
2812 (aopForRemat): added parameter 'bool result' in function declaration,
2813 (pic16_aopGet): return AOP_ACC when accessing WREG,
2814 (pic16_popGetTempReg): minor modification,

2825 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2826 call to allocReg, not by manually allocating a new one,
2827 (pic16_assignRegisters): now before going through the register
2828 allocating functions mark all registers as free. This eliminates some
2829 side effects resulting from peephole parser done earlier in the backbone
2831 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

2889 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
2890 which dumps before the function entry point a data byte which represents
2891 the number of the local variables used by the specified function, added
2892 'xinst' for initial support for Extended Instruction Support,
2893 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2894 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2895 port->fun_prefix anymore (may change later),
2896 (genFunction, genEndFunction): do not store/restore local registers for
2897 _main (this should take care the --main-return command line option in
2899 (genOr): removed some legacy pic-port instructions,
2900 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2901 performing operations with SFR's causes data to be written more than
2902 once to each SFR. Perhaps SFRs should be handled in special cases...
2903 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2905 * src/pic16/main.c (_process_pragma): stack bound checking did not take
2906 into account for stack starting position,

2908 --extended or -y for Extended Instruction Support,
2909 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
2910 (deassignLRs): *** perhaps the most important change, old 'for' code
2911 (commented out for reference), didn't account for some registers which
2912 were left marked 'not free' after a pointer operation. The change
2913 reduces register usage a lot in some cases

5182 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5184 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),

5188 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
5189 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
5190 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
5191 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
5192 always available in leading double underscore form. The C99 support is
5193 mostly missing, but it's a start.
5194 * support/regression/tests/bug-227710.c: fixed nonconforming use of
5195 reserved identifier "__data".
5197 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
5199 * src/mcs51/peeph.def: fixed bug 1170013

5241 immedDom() returning wrong block; probably fixes bug #1160833)
5243 2005-03-20 Borut Razem <borut.razem AT siol.net>
5245 * support/scripts/inc2h.pl: WIN32 port

5251 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
5253 * device/include/stdint.h: added
5254 * device/lib/abs.c: added

5273 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
5275 * device/lib/printf_large.c: removed inline assembly for portability and
5276 readability. Use printf_fast if speed or size are more important.
5277 * src/pic16/gen.c: removed conditions around use of DEBUGpc
5278 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
5280 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
5282 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
5283 prevent compiler warning
5285 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
5287 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
5288 moved to level 0 and declared as static. Also they are explicit
5289 placed in access bank. This was necessery because some times they
5290 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
5291 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
5292 optimizations. Currently only compare to unsigned char is implemented,
5293 * src/pic16/gen.c: added fReturnIdx array,
5294 * (struct resolvedIfx) is moved to gen.h and made public,
5295 * (struct _G): added sregsAlloc and sregsAllocSet fields,
5296 * (aopForSym): added an optimization to directly store in stack of
5297 the operand of a SEND iCode,
5298 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
5299 but as registers instead (AOP_REG) using the fReturnIdx array,
5300 * (pic16_freeAsmop): remove the freed register from the
5301 _G.sregsAlloc field,
5302 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
5303 a compare of 'WREG',
5304 * (pic16_popGetTempRegCond): changed function prototype, now
5305 function takes also a bitVector argument v which holds the current
5306 set of registers that are allocated for stack access by aopForSym,
5307 registers allocated in aopForSym for accessing stack symbols are not
5308 any more part of the functions usedRegs field,
5309 * (genCall): some times aopOp is called for a stack variable to be
5310 send, aopForSym might perform the push, if this is true make sure
5311 that genCall doesn't push the variable twice by testing _G.resDirect,
5312 * (genFunction): changed testing for unspecified interrupt number
5313 from 256 to INTNO_UNSPEC,
5314 * modified selection scheme of frame pointer generation. Previously
5315 if function did use local registers a frame pointer was generated,
5316 now a frame pointer is generated only if function has arguments
5317 (that need PLUSW2 register access), or has stack arguments, or the
5318 compiler is not instructed to omit the frame pointer,
5319 * (genEndFunction): before restoring local registers that were saved
5320 in the function preamble, also restore the registers that *might*
5321 have been allocated for stack access,
5322 * (genRet): removed some old comments,
5323 * (genCmp, the active (RN's) version): added a call to the
5324 pic16_genCmp_special function to perform the compare with a more
5325 robust and optimized way,
5326 * (genInline): a feature has been added in inline code generation,
5327 which allows a wildcard variable substitution when writing inline
5328 assembly. Code is incomplete and experimental therefore undocumented,
5329 * (genCast): changed order of aopOp for result and right to allow
5330 aopForSym to directly load the result if possible,
5331 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
5332 perform an optimized compare on some selected special occasions,
5333 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
5334 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
5335 generate an IVT any more,
5336 * src/pic16/main.c (pic16_optionsTable): added command line option
5338 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
5339 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
5341 * src/pic16/NOTES: Raphael Neider added in list of active developers
5342 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
5343 jumptable_end to prevent bug #,
5344 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
5345 inCond and outCond fields,
5346 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
5347 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
5348 turn off register spilling,
5349 * (packRegsForOneUse): synced with other ports' versions although it
5350 is not used currently,
5351 * (pic16_packRegisters): added an optimization while reading
5352 structure bitfields, some registers may be saved (malloc code is
5353 decreased by 80 bytes)
5355 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
5357 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
5358 left is a bitfield, if yes, then don't optimize assignment. Perhaps
5359 this can be optimized more?
5361 2005-03-10 Raphael Neider <rneider AT web.de>
5363 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
5364 genNearPointerGet): (hopefully) fixed access to bitfields via
5365 pointers (p->bitN = x; and x = p->bitN; failed)
5367 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

5410 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
5411 to keep the correct label reference count when adding/removing references
5412 to labels. A peephole file using this is appended to patch #1144962.

5544 * src/pic16/main.c (_process_pragma): fixed another malloc bug
5545 (sizeof(sectNames) changed to sizeof(sectName))
5546 Both patches fix segfaults under MinGW.

5553 of (byte sized) temporaries (assign them to WREG for now)
5554 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
5555 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
5556 this might fix SIGSEGVs on MinGW...
5557 * src/SDCCopt.c (killDeadCode): restored original behaviour
5558 (volatile operands might get thrown away though)
5560 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
5562 * src/pic16/gen.c: fixed bug #1106975,

5997 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5999 Adding support for replacing ljmps with sjmps in jumptables
6000 generated for switch statements. For now you need to set the
6001 environment variable SDCC_SJMP_JUMPTABLE to enable this.
6002 Now 4 algorithms for mcs51 jumptable generation are used:
6003 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
6004 addresses loaded pc-relative for up to 112 cases and stack-pushing
6005 target addresses loaded with offset from dptr for up to 256 cases.
6007 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
6008 * src/mcs51/main.c: adapted constants for switch table generation
6009 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

6031 Large cummulative patch for pic16 port.
6032 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
6033 to call when a stack overflow occurs,
6034 * (malloc.h): added CVS Id tag,
6035 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
6037 * added libc directory. The current version of LibC contains string
6038 functions, ctype functions and macros and some functions of the
6039 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
6040 be extensively tested in the future. Standard disclaimer here.
6041 Library is not automatically build yet. But one can build it by
6042 invoking 'make' inside the libc directory.
6043 * added ADC library under libio. Preliminary version yet.
6045 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
6046 * src/pic16/gen.c (aopForRemat): asmop size is filled by
6047 aopForRemat() now and not by pic16_aopOp(),

6049 temporary registers, its a buggy feature and will be removed,
6050 * (pic16_popGet): set register instance field in AOP_CRY,
6051 * (pic16_outBitC): fixed for results in size greater than 1,
6052 * (genUminusFloat): fixed for pic16, ported code from mcs51,
6053 * (pic16_storeForReturn): optimized return of 0,
6054 * (genCmp): experimental code for new genCmp which uses PIC18's
6055 special compare&skip instructions. Initial tests fail some times
6056 with variables grater than 1 byte in size, so new code is disabled,
6057 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
6059 * (genCast): began a fix to optimize the casting of a bit to another
6060 bit, now assigning a bitfield to another bitfield will fail, sorry,
6061 * src/pic16/main.c: disabled the use of lr-support feature,
6062 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
6063 * added some function prototypes, added function _debugf prototype,
6064 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
6065 bits with offset (case PO_GPR_BIT),
6066 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
6068 * (isBankInstruction): modified to return 0 for no banking instruction,
6069 and 1 for banking instruction,
6070 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
6071 caused stop processing pCodes after a inline assembly block,
6072 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
6073 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
6074 registers when it shouldn't,
6075 * src/pic16/ralloc.c (allocReg): add preliminary support for
6076 supporting a limited set of temporary registers,
6078 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6080 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
6081 genDataPointerSet): ensure assignments always copy in MSB to LSB
6083 (loadRegFromAop): recognize CLRH optimization,
6084 (genFunction): optimize RECEIVE iCodes in reentrant functions
6086 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6088 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

6098 * device/lib/_gptrgetc.c (_gptrgetc),
6099 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
6100 instead of sjmp to ret
6101 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
6102 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
6104 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

9086 loaded with the linker search paths (-L arguments) and the libraries
9087 to be linked with the current source (-l arguments). Changes
9088 currently will affect only the pic16 port.
9089 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
9090 include path the port specific paths and port specific libraries,
9091 * gplink command now contains the $3 argument,
9092 * src/pic16/device.h,
9093 * src/pic16/device.c,: structure PIC_device is made public and
9094 renamed to PIC16_device, the same for variable Pics which is renamed
9095 to Pics16. Updated all references to them.
9096 * src/pic16/glue.c (pic16glue): corrected bug with code
9097 initialization which bypassed the variable initializations block.
9099 * device/lib/pic16/Makefile.rules: removed --penable-stack from
9100 COMPILE_FLAGS and added the --nostdinc option
9102 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9104 * device/include/mc68hc908jb8.h: Register defs for another member
9105 of the hc08 family. Contributed by Bjorn Bringert - thanks!
9107 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
9109 Documenting changes from previous commits.
9110 * configure.in (version 1.56),
9111 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
9112 when generating output files to configure the pic16 library,
9113 but now I've commented it out, since gputils aren't installed in the
9114 SF compile farm, so library won't compile
9116 * device/lib/Makefile.in (version 1.56): initially I've added in
9117 target 'all' the prerequestive 'model-pic16' so it compiled the
9118 pic16 library, but now I've commented it out for the same reasons
9120 * added targets 'model-pic16' and 'objects-pic16' to compile the
9122 * added target 'port-specific-objects-pic16' to handle the
9123 generated libraries and copy them into the build/ directory
9124 * added target 'clean-intermediate-pic16' to clean intermediate
9125 files into pic16 directory
9126 * in target 'installdirs' added line to create directory pic16 in
9127 the installation path
9129 * device/include/Makefile.in (version 1.11): in target 'install'
9130 added lines to copy all header files to installation path,
9131 * in target 'installdirs' added line create directory for pic16
9132 headers in the installation path

9147 * src/z80/main.c (_parseOptions): fixed the portmode= command line
9148 option so that it actually works. Made it specific to the z80, since
9149 the gbz80 doesn't have these kinds of I/O ports.
9151 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9153 * device/include/z180.h,

9166 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9168 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
9169 changed interrupt vector table generation to only emit declared vectors.

9175 Mainly changes to support compilation of the device libraries
9176 * src/pic16/device.c: stack is allocated via symbol and not
9177 via literal number. The symbol is placed in the corresponding
9178 position of the data ram
9179 * (pic16_dump_section): relocatable and absolute uninitialized
9180 data are now emitted in sorted order to reduce section naming,
9181 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
9182 weren't marked as being in the access bank,
9184 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
9186 Added portion of GNU PIC Library under the directory
9187 device/include/pic16 and device/lib/pic16. These files
9188 contain the declarations of SFRs for the PIC18Fxx2 devices.
9189 The directory is initialized via configure from toplevel.
9191 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
9193 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
9194 the spilllocations to be compared correctly
9196 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
9198 * src/SDCCast.c (decorateType): fixed bug introduced today
9200 2004-01-12 Borut Razem <borut.razem AT siol.net>

9218 * doc/sdccman.lyx: Moved and added some sections, small changes
9219 all over. Telling LaTeX to be less strict with word spacing
9220 to better keep the right margin. Changed some notes about
9221 maintainance of the ports in section 3.2.1 - is it OK like this?
9223 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
9225 SDCC source changes:
9226 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

9260 UPPER for immediate operands,
9261 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
9263 * src/pic16/peeph.def: all peepholes with movff are commented out,
9264 because there is a problem in the pcode peep optimizer,
9265 * src/pic16/ralloc.c: the register allocator can now reuse local
9266 function symbols for another function. This saves register usage.
9267 * src/pic16/ralloc.h: added flag isLocal in structure regs,
9269 Added file src/pic16/NOTES with information about program writing on
9270 the current port version.

9279 * src/SDCCmain.c : fixed #872250: -l command line defined library
9280 files are scanned before standard library files
9282 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9302 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9305 * src/z80/main.c: added missed needLinkerScript flags (more than
9306 one port structure defined in these file)
9307 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

9323 needLinkerScript flag
9325 * src/pic16/gen.c (genAddrOf): fixed bug #863624
9326 * src/pic/glue.c: added variable udata_section_name to
9327 override default uninitialized data segment definition for
9328 devices only with SHAREBANK memory (reported from Erik Epetrich)
9329 * (pic14emitOverlay): modified to emit a commented overlay segment
9330 directive when no overlay data exist
9331 * (picglue): modified to emit uninitialized data segment
9332 according to udata_section_name
9333 * src/pic/main.c (_pic14_parseOptions): added command line

9337 arguments via -W option
9338 * src/pic16/main.c: added $l in _asmCmd, changed extension for
9339 object file from '.rel' to '.o' in port->linker structure,
9340 changed size of fptr from 2 to 3 in port structure
9342 2004-01-07 Borut Razem <borut.razem AT siol.net>
9344 * support/scripts/sdcc.nsi: update PATH
9345 * support/scripts/sdcc.ico: craeted
9347 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>

9350 * doc/Makefile: fix install
9352 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9354 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
9356 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

9358 include information about variables allocated to the overlay
9361 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9363 * as/mcs51/lkmain.c: Help about -Y option

9375 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9377 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
9378 (default behaviour).
9380 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9382 A python script to validate compiler diagnostic messages. It can be
9383 used to verify that sdcc complains about bad c source code and
9384 gives a good location of the error.
9385 * support/valdiag/Makefile,
9386 * support/valdiag/valdiag.py,
9387 * support/valdiag/tests/*
9389 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9391 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

9402 * src/common.h: added ifndef/define/endif macros
9403 around the header file.
9404 Bug reported from Jesus Calvino-Fraga
9406 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
9408 * sdcc.spec: updated
9409 * device/include/Makefile.in: don't install CVS directories
9410 * device/lib/Makefile.in: added removal of CVS directories after install
9411 * doc/Makefile: fixed install, added local_icons
9412 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
9413 * src/mcs51/gen.c (genRightShift): fixed bug #870788
9414 * src/ds390/gen.c (genRightShift): fixed bug #870788
9415 * src/SDCCast.c (decorateType): fixed bug #870781
9417 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9419 PIC16 port related changes:
9420 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
9421 added variable stackPos,
9423 * gen.c: genCall, assignResultValue: added support for
9424 pushing/retrieving function parameters to/from stack,
9425 genFunction,genEndFunction: setup stack frame for the
9427 genAddrOf: will be changed according to bug 863624
9429 * added files genutils.c and genutils.h which contain gen*
9430 debugged and optimised functions extracted from gen.c
9432 * glue.c: added variable 'externs' which holds extern symbols,
9433 pic16emitRegularMap: is modified to properly handle relocatable
9434 symbols under the new scheme,
9435 pic16createInterruptVect: is modified
9436 pic16printPublics: is modified to emit 'global' assembler directives,
9437 added pic16_printExterns to print extern symbols,
9438 pic16glue: initializes stack/frame pointer in the beginning of
9439 the assembly output. Temporary hack, will be corrected later,
9440 because gplink yet does not support stack and SDCC does not
9441 yet support a type of crt0.o object to create the final binary.
9443 * Removed many lines that contain 8051 legacy code.
9444 * The code is finally placed under a 'code' directive.
9445 * Added port specific options.
9447 * _process_pragma: simplified since now we do not need *special*
9448 include file to define SFR registers. But a separate header
9449 will be needed. This will be developed later.
9450 * _pic16_parseOptions: added, parses port specific options:
9451 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9452 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9453 --preplace-udata-with=
9455 * _pic16_setDefaultOptions: modified to initialize section names,
9456 but hack is temporarly out of order since it needs improvement.
9457 * _pic16_genAssemblerPreamble: configuration words are emitted by
9458 their address instead of their name. This part is incomplete and
9459 supports only the 18Fxx2 devices. Other devices will emit an error
9460 during assembly since they do not contain the same set of config
9462 * _pic16_genIVT: is modified,
9464 * pcode.c: added definitions for some hardware registers that are needed
9466 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9467 All PCI entries are updated. Now LFSR is supported.
9468 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9469 * added pic16_newpCodeOpLit2 to support instructions with
9470 two literal arguments
9471 * pic16_pCode2str: corrected code that emits assembler instructions
9472 with two literal operands and those that have an access bit modifier
9473 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9474 this fixes a bug which caused some labels to be lost, when an
9475 assembler directive was added, i.e. banksel,
9476 * pic16_FixRegisterBanking: improved logic that causes the insertion
9478 * InlineFunction: functions that are called once, are not any more
9479 inlined. This can be a port option in the future,
9481 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9483 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9484 hold the corresponding uninitialized symbols,
9485 * pic16_allocProcessorRegister: registers have explicit marked the
9487 * pic16_allocInternalRegister: registers are explicit marked as
9489 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9490 processing list, so bit registers were lost,
9493 * ralloc.h: added field 'accessBank' and original symbol operand
9494 in register definition,
9495 * removed the field isMapped from register definition,
9497 ** Several functions have been removed from various sources:
9498 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9499 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9500 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9501 pic16_assignRelocatableRegisters
9503 ** others have been introduced:
9504 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9505 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9507 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9509 * support/scripts/inc2h.pl: changed definition of BIT_AT
9510 to emit 'sbit at' instead of 'bit at'. This was a request.
9512 PIC16 port related preliminary changes:
9513 * gen.c: prefixed function popRegFromString with
9514 pic16_ and all references to it corrected
9515 * pcode.c: all pic16_pc_* hardware registers prefixed
9516 with underscore (_),
9517 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9518 * ralloc.c: newReg(): when register is REG_SFR then
9519 set address to rIdx,
9520 pic16_allocProcessorRegister(): marks register wasUsed=0
9521 pic16_writeUsedRegs(): added a call to assign processor
9522 registers via pic16_assignFixedRegisters
9524 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9526 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9527 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9528 variables in unused register banks. Also the SSEG is placed
9529 wherever there is enough space for it, and IDATA can be anywhere
9530 in internal RAM. For now compile using -Wl-Y[stack_size].
9531 The mem file is different for this option as well, since it
9532 makes no sense of talking about DSEG lenght.
9534 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9536 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9537 in certain cases, e.g. when ROM assignment, patch provided
9538 from Albert den Haan.
9540 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

10546 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
10547 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
10548 If they pop r0/r1 they must be called in the opposite order than aopOp().
10549 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
10550 (resp. --stack-auto), prepared for --xstack
10552 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10554 * doc/sdccman.lyx: reverted tables to those in cvs 1.64
10556 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10558 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
10559 these ports have their own __sdcc_external_start()
10561 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
10563 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10564 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10565 type for bits was changed. It resulted in bit variables becoming
10566 global, which is not permitted in PIC 14 assembly output.
10568 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10570 * doc/sdccman.lyx: various additions and updates. Rearranged sections
10572 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10574 Z80 and MCS51 linkers complaint if a public symbol is defined
10575 in more than one library module:

10583 A few small changes that speed up the peephole optimizer.
10587 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10589 Try to make the peephole optimizer smarter by maintaining
10590 an association between the assembly source code and the
10591 iCodes that originated them. Put this information to use
10592 with a new peephole rule condition "notVolatile" so that
10593 the rules can be aggressive yet still safe.
10598 * src/mcs51/peeph.def
10600 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10604 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10605 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10606 if the left or right operand symbols have the accuse flag set.
10608 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10610 Changed the type of the result of the ! (NOT) operator to char;
10611 previously it returned the same type as the source. This allows
10612 us to eliminate all the genFloatNot functions (all of its target
10613 implementations were very buggy) since !float can use the same
10616 * src/SDCCicode.c (ast2iCode): ! returns char
10617 * src/mcs51/gen.c (genNot, genNotFloat),
10618 * src/ds390/gen.c (genNot, genNotFloat),
10619 * src/z80/gen.c (genNot, genNotFloat),
10620 * src/pic/gen.c (genNot, genNotFloat),
10621 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

10625 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10626 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10627 during interrupts. Ensure WSAVE is located at a shared bank address.
10628 2. Fixed page selection in some places
10629 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10630 the registers name strings.
10631 4. Fixed "signed / unsigned compare" compiler warnings.
10632 5. The PIC port manages its own allocation of the general purpose
10633 registers, but makes no attempt to reuse them. As a result when
10634 compiling it soon runs out of general purpose registers. Some
10635 additional code was added to the files pcode.c and device.c to walk
10636 through the function call tree and rename the registers so that they
10646 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10647 genPlus() & genMinus() when the result is the same as left or right
10649 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10653 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10655 Made bitfield a distinct type from bit so that bitfields
10656 convert as per ANSI C and bits retain their traditional
10657 boolean style behaviour. Implemented bitfield support in
10665 * src/ds390/gen.c: bit v bitfield split
10666 * src/z80/gen.c: New support for bitfields
10667 * support/regression/tests/bitfields.c: reenabled z80,
10670 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10672 Rules 246.x, 247.x relate to bitfields, the others speed up
10673 access to xdata mapped I/O devices.
10675 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
10677 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10679 Cleaned up genPackBits and genUnpackBits and added two helper
10680 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
10681 for literal assignments in genPackBits (thanks to Frieder for
10687 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10689 Fixed bug #748310 (pointer to function type mishandled when the
10690 function name is omitted). Also fixed a SIGSEGV when a function
10691 attribute (reentrant, etc) is used on a non-function or on a
10692 function but misplaced before the parameter list.
10694 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
10696 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
10697 * support/Util/SDCCerr.h,
10698 * support/Util/SDCCerr.c: Added func attr misuse error msg
10700 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
10702 Fixed bug #787649 by anonymous
10703 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
10704 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
10706 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10719 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10721 Made the constant following the "interrupt" keyword optional. If
10722 omitted, the function will not automatically be given an entry
10723 in the interrupt vector table (similar to #pragma NOIV, but
10724 less syntacticly kludgy). The interrupt number is also now
10725 range checked. Also fixed a bug in the high order bit example

10741 * src/SDCCsymt.c (computeType): literals are handled the same way as any
10743 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
10744 be re-activated by defining REDUCE_LITERALS)
10745 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
10746 unsigned, but are signed by default
10747 * src/SDCCval.c (constVal): rearranged
10748 * src/SDCCval.c (valMod): preliminary fix
10749 * src/SDCCval.c (valCastLiteral): use TYPE_* types

11201 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
11202 the regression tests I'm not brave enough to enable 245.b, 245.c
11203 * doc/sdccman.lyx: added latex preamble for hyperref package.
11204 Using pdflatex this will give you a hyperlinked pdf file with

11255 added if/endif conditional macros to remove options help
11256 messages from optionsTable when a port is not configured, added
11257 support for the PIc16 port in the ports table, when executing
11258 the compiler with no port specified on command line, a default
11259 port is selected with the new macro DEFAULT_PORT which is
11260 defined in port.h, in setDefaultOptions() linkOptions is removed
11261 from initialization assignment, since now it is a set,
11262 parseCmdLine uses setParseWithComma for linkOptions, in
11263 linkEdit() linkOptions are accessed with new function indexSet()
11264 which returns the i'th item of a set variable. See SDCCset.c, in
11265 linkEdit() when calling buildCmdLine(), added linkOptions as
11266 last argument. Now users can pass arguments to gplink via the
11267 -Wl option, main() uses pic16glue() to glue up pic16 programs
11268 * src/SDCCpeeph.c: various changes to support pic16
11269 * src/SDCCset.c: added function void *indexSet(set *, int) to

11279 * src/pic16/glue.c: commented out some error producing lines
11280 * src/pic16/main.c: __config directives are commented out to stop
11281 gpasm complaining and test the linkage with gplink, _linkCmd and
11282 _asmCmd changed to be more gplink and gpasm friendly
11283 * src/pic16/peeph.def: peep rule 3 is commented out, since it
11284 produced an error when parsed, peep rule 12 is added to utilize
11285 movff, but it is commented out since the pCode does not support
11286 yet a command with 2 address arguments
11288 2003-05-18 <johan AT balder>
11290 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

12379 added aopGetUsesAcc() function to allow binary operators to
12380 fetch their operands in the correct order; made genMinus() emit
12381 compact code for X = LITERAL - Y
12383 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12384 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
12385 sprintf() in line 1267.
12387 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12388 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
12391 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12392 Changes to aslink (All the changes are marked with 'JCF'):
12394 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
12397 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
12398 area BSEG. Also moves, if possible, the DATA area down into the internal
12399 ram so more space is available.
12401 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
12404 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
12405 not bytes. Function summary() which creates a memory usage summary
12406 file with extension .mem. Reports of overlaping stack and small stack
12407 size. If the space for the stack is less than 16 bytes aslink trows a
12410 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
12411 the 8051. Option 'y' for memory summary output file.
12413 Changes to sdcc (All the changes are marked with 'JCF'):
12415 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
12417 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
12418 overlaying area for it (uses RegBankUsed[4]).
12420 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
12421 bank zero as used by default. By default aslink locates the stack
12422 (equivalent to --stack-after-data). Pass option 'y' to aslink for
12423 the creation of the .mem file. Delegates the allocation of data area
12424 to aslink (it is not longer 0x30 by default). If --stack-loc passes
12425 the begining of the stack area to aslink.
12427 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
12428 glue() in SDCCglue.c creates an area for it.
12430 2002-09-03 Borut Razem <borut.razem AT siol.net>
12431 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12432 sdcc/src/pic/glue.c:
12433 introduced atexit() handler for teporay files removal in case of
12434 errors, assertions, ...
12436 2002-08-29 Borut Razem <borut.razem AT siol.net>
12437 * sdcc/support/cpp2/auto-host_vc_in.h:
12438 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12439 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12440 Maybe there is a similar problem with BORLANDC? It should be checked!
12442 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12443 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12444 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12445 was not executed, and the compiler (cl) launched a warning:
12446 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12448 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12449 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
12451 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
12452 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
12454 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12455 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
12456 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
12457 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12458 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
12459 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
12460 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
12461 - added Release configuration in VS projects
12462 - review of compiler an linker options
12463 - VC .exe files are generated in bin_vc directory, not to interfere
12464 with binaries generated from other projects (cygwin, mingw, bcc ...)
12466 * sdcc/src/yacc.dsp: added
12468 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12469 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12470 and insert the version number definitions from .version
12472 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12474 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
12475 added - genarate auto-host.h using auto-host_vc_in.h as template
12478 removed from CVS, generated automatically
12480 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
12481 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12483 2002-08-11 Borut Razem <borut.razem AT siol.net>
12484 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12486 2002-08-10 Borut Razem <borut.razem AT siol.net>
12487 * src/SDCCmain.c (main):
12488 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12489 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12490 The consequence was that some temporary files were not removed.
12493 unification of code in functions tempfilename() and tempfile():
12494 function tempnam() is defined in Visual Studio 6.0 and .NET
12496 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12498 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12499 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
12500 - removed compiler command line option /WX: Treats all warnings as errors
12501 - update a list of source files, included into the project
12503 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12504 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12505 changed project type to Generic Project so that can be correcly converted to VS.NET project
12507 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12509 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
12511 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
12513 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12514 added return 0 statements after assert() to make compiler happy
12516 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12517 added newline in the def file to keep MSC compiler satisfied
12519 * sdcc/src/z80/gen.c:
12520 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
12521 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
12522 - solved MSC error in function aopDump()
12524 * sdcc_vc.h: define PREFIX as "\\sdcc"
12526 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
12527 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

12530 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
12531 - Rewrote the register banking algorithm.
12532 - Added pCode live-range analysis to registers (for now, only non-used and
12533 singly-used registers optimized away)
12535 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
12537 * 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.

12564 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
12566 2002-03-28 Johan Knol <johan AT balder>
12568 * src/SDCCval.c: fixed bug #532436
12570 2002-03-14 Scott Dattalo <scott AT dattalo.com>
12572 Added "char *Processor" field to the port structure.
12575 Added -p option. Allows port dependent processor to be specified.
12578 Initialized the new field char *Processor field to NULL in all ports
12581 Compiler generated registers for interrupt context saving
12582 were not getting allocated.
12584 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
12587 Fixed left shift. Will promote the left side of a left shift
12588 if a) left shifting more than size of operand or b) when assigned
12589 to something size > size of left side
12591 2002-03-14 Scott Dattalo <scott AT dattalo.com>

12595 analysis is restructured. ...
12597 * src/pic/device.h:
12600 * src/pic/device.c:
12601 Added. device.c is a PIC port hack to accomodate variations
12604 2002-03-13 Michael Hope <michaelh AT vroom>
12606 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
12608 2002-03-04 johanknol <johanknol AT manik>
12610 * /src/SDCCval.c: fixed

12699 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
12701 * sdcc/src/SDCCloop.c:
12702 Previous fix was not good. basic blocks that have "break" or "return" are
12703 not really partof a loop , but live ranges used in these blocks should
12704 be live thru the entire loop, so set partOfLoop but don't add them to
12707 2002-02-21 <johan AT FRIJA>
12709 * src/SDCCcse.c: fixed bug #514308
12711 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

12715 statement inside a loop, it was not being considered part of the loop.
12717 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
12719 2002-02-10 Karl Bongers <karl AT turbobit.com>
