2470 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2472 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2473 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2475 One basic decision: e.g. src/clean.mk includes further files. In order
2476 to make this work there are two solutions:
2477 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2478 run configure on them. This way they can use
2479 'include $(srcdir)/port-clean.mk'
2480 - always include clean.mk by the Makefile at the same level. To avoid
2481 that `make clean` tries to include and build Makefile.dep the
2482 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2483 implemented, because now even `make uninstall` doesn't create
2484 Makefile.in. clean.mk could be eliminated by pasting it in
2487 * debugger/mcs51/Makefile.in: build own objects from library sources
2488 (SLIB, SDCC) in current directory
2490 * configure, configure.in: renamed --disable-device-lib-build in
2491 --disable-device-lib; added --enable-doc, the required tools are
2492 searched by configure; added result message; the toolchain for the
2493 belonging ports are now only built, if the port is enabled.
2495 * support/regression/*: all output is written in directory gen, because
2496 the fwk and ports directories don't livet in the build tree using vpath
2498 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2499 --disable-device-lib, added --enable-doc, added section VPATH
2501 * sim/ucsim/configure.in,
2502 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2503 z80 are enabled by default
2505 2006-04-24 Raphael Neider <rneider AT web.de>
2507 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2508 to config word, "pic14_"-prefixed some extern functions
2509 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2510 config word has been found
2511 * src/pic/device.h: added prototypes
2512 * src/pic/pcode.c: added "pic14_"-prefix where needed
2513 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
2515 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
2517 (pic14emitRegularMap): ignore config words,
2518 (pic14createInterruptVect): moved generating __config directives away
2519 (picglue): have __config directives emitted
2521 2006-04-24 Borut Razem <borut.razem AT siol.net>

2528 registers that have not been assigned proper liveranges,
2529 fixes #1469504 and #1474602,
2530 (pCodeRegOptimizeRegUsage): fixed typo in comment
2532 2006-04-24 Borut Razem <borut.razem AT siol.net>
2534 * device/examples/main8051.c: deleted - it was removed from CVS
2535 24.mar.2000 and after that modified 18.feb.2001, so it reappered
2536 after the transition to Subversion
2537 * src/SDCCalloc.h: deleted - it was removed from CVS
2538 3.feb.2001 and after that modified 18.feb.2001, so it reappered

2777 interrupts need an interrupt number now if they are made critical),
2778 and enabled nesting of critical functions though not for gbz80
2779 (genCritical, genEndCritical): added functions
2780 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
2781 * src/z80/mappings.i: added "ei" to all mappings

2793 the left operand is shorter than the result (c* = lit-c* + int),
2795 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
2798 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2800 * src/.version: increased version number to 2.5.5
2801 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
2802 linking is done manually in pic16 port's _linkEdit,
2803 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
2804 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
2805 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
2806 allocate asmop as AOP_ACC,
2807 (aopForRemat): added parameter 'bool result' in function declaration,
2808 (pic16_aopGet): return AOP_ACC when accessing WREG,
2809 (pic16_popGetTempReg): minor modification,

2820 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2821 call to allocReg, not by manually allocating a new one,
2822 (pic16_assignRegisters): now before going through the register
2823 allocating functions mark all registers as free. This eliminates some
2824 side effects resulting from peephole parser done earlier in the backbone
2826 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

2886 the number of the local variables used by the specified function, added
2887 'xinst' for initial support for Extended Instruction Support,
2888 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2889 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2890 port->fun_prefix anymore (may change later),
2891 (genFunction, genEndFunction): do not store/restore local registers for
2892 _main (this should take care the --main-return command line option in
2894 (genOr): removed some legacy pic-port instructions,
2895 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2896 performing operations with SFR's causes data to be written more than
2897 once to each SFR. Perhaps SFRs should be handled in special cases...
2898 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2900 * src/pic16/main.c (_process_pragma): stack bound checking did not take

2905 (deassignLRs): *** perhaps the most important change, old 'for' code
2906 (commented out for reference), didn't account for some registers which
2907 were left marked 'not free' after a pointer operation. The change
2908 reduces register usage a lot in some cases

5175 on rIfx (genCmp was broken)
5177 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5179 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
5180 * src/z80/main.c (_keywords[]),
5181 * src/SDCCglobal.h (struct options),
5183 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
5184 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
5185 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
5186 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
5187 always available in leading double underscore form. The C99 support is
5188 mostly missing, but it's a start.
5189 * support/regression/tests/bug-227710.c: fixed nonconforming use of
5190 reserved identifier "__data".
5192 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

5236 immedDom() returning wrong block; probably fixes bug #1160833)
5238 2005-03-20 Borut Razem <borut.razem AT siol.net>
5240 * support/scripts/inc2h.pl: WIN32 port

5268 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
5270 * device/lib/printf_large.c: removed inline assembly for portability and
5271 readability. Use printf_fast if speed or size are more important.
5272 * src/pic16/gen.c: removed conditions around use of DEBUGpc
5273 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
5275 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
5277 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
5278 prevent compiler warning
5280 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
5282 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
5283 moved to level 0 and declared as static. Also they are explicit
5284 placed in access bank. This was necessery because some times they
5285 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
5286 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
5287 optimizations. Currently only compare to unsigned char is implemented,
5288 * src/pic16/gen.c: added fReturnIdx array,
5289 * (struct resolvedIfx) is moved to gen.h and made public,
5290 * (struct _G): added sregsAlloc and sregsAllocSet fields,
5291 * (aopForSym): added an optimization to directly store in stack of
5292 the operand of a SEND iCode,
5293 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
5294 but as registers instead (AOP_REG) using the fReturnIdx array,
5295 * (pic16_freeAsmop): remove the freed register from the
5296 _G.sregsAlloc field,
5297 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
5298 a compare of 'WREG',
5299 * (pic16_popGetTempRegCond): changed function prototype, now
5300 function takes also a bitVector argument v which holds the current
5301 set of registers that are allocated for stack access by aopForSym,
5302 registers allocated in aopForSym for accessing stack symbols are not
5303 any more part of the functions usedRegs field,
5304 * (genCall): some times aopOp is called for a stack variable to be
5305 send, aopForSym might perform the push, if this is true make sure
5306 that genCall doesn't push the variable twice by testing _G.resDirect,
5307 * (genFunction): changed testing for unspecified interrupt number
5308 from 256 to INTNO_UNSPEC,
5309 * modified selection scheme of frame pointer generation. Previously
5310 if function did use local registers a frame pointer was generated,
5311 now a frame pointer is generated only if function has arguments
5312 (that need PLUSW2 register access), or has stack arguments, or the
5313 compiler is not instructed to omit the frame pointer,
5314 * (genEndFunction): before restoring local registers that were saved
5315 in the function preamble, also restore the registers that *might*
5316 have been allocated for stack access,
5317 * (genRet): removed some old comments,
5318 * (genCmp, the active (RN's) version): added a call to the
5319 pic16_genCmp_special function to perform the compare with a more
5320 robust and optimized way,
5321 * (genInline): a feature has been added in inline code generation,
5322 which allows a wildcard variable substitution when writing inline
5323 assembly. Code is incomplete and experimental therefore undocumented,
5324 * (genCast): changed order of aopOp for result and right to allow
5325 aopForSym to directly load the result if possible,
5326 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
5327 perform an optimized compare on some selected special occasions,
5328 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
5329 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
5330 generate an IVT any more,
5331 * src/pic16/main.c (pic16_optionsTable): added command line option
5333 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
5334 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
5336 * src/pic16/NOTES: Raphael Neider added in list of active developers
5337 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
5338 jumptable_end to prevent bug #,
5339 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
5340 inCond and outCond fields,
5341 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
5342 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
5343 turn off register spilling,
5344 * (packRegsForOneUse): synced with other ports' versions although it
5345 is not used currently,
5346 * (pic16_packRegisters): added an optimization while reading
5347 structure bitfields, some registers may be saved (malloc code is
5348 decreased by 80 bytes)
5350 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
5352 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
5353 left is a bitfield, if yes, then don't optimize assignment. Perhaps
5354 this can be optimized more?
5356 2005-03-10 Raphael Neider <rneider AT web.de>
5358 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
5359 genNearPointerGet): (hopefully) fixed access to bitfields via
5360 pointers (p->bitN = x; and x = p->bitN; failed)
5362 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
5364 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

5405 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
5406 to keep the correct label reference count when adding/removing references
5407 to labels. A peephole file using this is appended to patch #1144962.

5539 * src/pic16/main.c (_process_pragma): fixed another malloc bug
5540 (sizeof(sectNames) changed to sizeof(sectName))
5541 Both patches fix segfaults under MinGW.

5547 * src/pic16/gen.c (pic16_aopOp,pic16_popGet): added handling
5548 of (byte sized) temporaries (assign them to WREG for now)
5549 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
5550 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
5551 this might fix SIGSEGVs on MinGW...
5552 * src/SDCCopt.c (killDeadCode): restored original behaviour
5553 (volatile operands might get thrown away though)
5555 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
5557 * src/pic16/gen.c: fixed bug #1106975,

5562 * added function attribute 'shadowregs' to take advantage of shadow
5564 * added function attribute 'wparam' as an alternative to the wparam
5566 * support/Utils/SDCCerr.[ch]: added error E_SHADOWREGS_NO_ISR when
5567 user declares a non-ISR function as 'shadowregs',

5996 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5997 Now 4 algorithms for mcs51 jumptable generation are used:
5998 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
5999 addresses loaded pc-relative for up to 112 cases and stack-pushing
6000 target addresses loaded with offset from dptr for up to 256 cases.
6002 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
6003 * src/mcs51/main.c: adapted constants for switch table generation
6004 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

6009 * support/regression/tests/bug1057979.c: added test for bug 1073386
6011 2004-11-25 Vangelis Rokas <vrokas AT otenet.gr>
6013 * src/pic16/pcode.c: fixed bug which may produce error in non-GNU
6016 2004-11-25 Vangelis Rokas <vrokas AT otenet.gr>
6018 * src/pic16/device.h,
6019 * src/pic16/genarith.c,
6022 * src/pic16/pcode.c: applied patches #1068154 and #1070213
6024 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
6026 Large cummulative patch for pic16 port.
6027 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
6028 to call when a stack overflow occurs,
6029 * (malloc.h): added CVS Id tag,
6030 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
6032 * added libc directory. The current version of LibC contains string
6033 functions, ctype functions and macros and some functions of the
6034 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
6035 be extensively tested in the future. Standard disclaimer here.
6036 Library is not automatically build yet. But one can build it by
6037 invoking 'make' inside the libc directory.
6038 * added ADC library under libio. Preliminary version yet.
6040 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
6041 * src/pic16/gen.c (aopForRemat): asmop size is filled by
6042 aopForRemat() now and not by pic16_aopOp(),
6043 * (pic16_popGetTempReg): removed warning messgae when allocating
6044 temporary registers, its a buggy feature and will be removed,
6045 * (pic16_popGet): set register instance field in AOP_CRY,
6046 * (pic16_outBitC): fixed for results in size greater than 1,
6047 * (genUminusFloat): fixed for pic16, ported code from mcs51,
6048 * (pic16_storeForReturn): optimized return of 0,
6049 * (genCmp): experimental code for new genCmp which uses PIC18's
6050 special compare&skip instructions. Initial tests fail some times
6051 with variables grater than 1 byte in size, so new code is disabled,
6052 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
6054 * (genCast): began a fix to optimize the casting of a bit to another
6055 bit, now assigning a bitfield to another bitfield will fail, sorry,
6056 * src/pic16/main.c: disabled the use of lr-support feature,
6057 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
6058 * added some function prototypes, added function _debugf prototype,
6059 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
6060 bits with offset (case PO_GPR_BIT),
6061 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
6063 * (isBankInstruction): modified to return 0 for no banking instruction,
6064 and 1 for banking instruction,
6065 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
6066 caused stop processing pCodes after a inline assembly block,
6067 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
6068 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
6069 registers when it shouldn't,
6070 * src/pic16/ralloc.c (allocReg): add preliminary support for
6071 supporting a limited set of temporary registers,
6073 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6075 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
6076 genDataPointerSet): ensure assignments always copy in MSB to LSB
6078 (loadRegFromAop): recognize CLRH optimization,
6079 (genFunction): optimize RECEIVE iCodes in reentrant functions
6081 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6083 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
6084 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
6086 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

6097 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
6099 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

9081 loaded with the linker search paths (-L arguments) and the libraries
9082 to be linked with the current source (-l arguments). Changes
9083 currently will affect only the pic16 port.
9084 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
9085 include path the port specific paths and port specific libraries,

9102 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
9104 Documenting changes from previous commits.
9105 * configure.in (version 1.56),
9106 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
9107 when generating output files to configure the pic16 library,
9108 but now I've commented it out, since gputils aren't installed in the
9109 SF compile farm, so library won't compile
9111 * device/lib/Makefile.in (version 1.56): initially I've added in
9112 target 'all' the prerequestive 'model-pic16' so it compiled the
9113 pic16 library, but now I've commented it out for the same reasons
9115 * added targets 'model-pic16' and 'objects-pic16' to compile the
9117 * added target 'port-specific-objects-pic16' to handle the
9118 generated libraries and copy them into the build/ directory
9119 * added target 'clean-intermediate-pic16' to clean intermediate
9120 files into pic16 directory
9121 * in target 'installdirs' added line to create directory pic16 in
9122 the installation path
9124 * device/include/Makefile.in (version 1.11): in target 'install'
9125 added lines to copy all header files to installation path,
9126 * in target 'installdirs' added line create directory for pic16
9127 headers in the installation path
9129 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

9142 * src/z80/main.c (_parseOptions): fixed the portmode= command line
9143 option so that it actually works. Made it specific to the z80, since
9144 the gbz80 doesn't have these kinds of I/O ports.
9146 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9148 * device/include/z180.h,

9154 * device/lib/_strcmp.c,
9155 * device/lib/_strtok.c: fixed pragmas to non-deprecated form
9156 * src/z80/main.c (_process_pragma): add support for pragmas bank and
9157 portmode; added deprecation warning for bank= and protmode= forms.
9158 Also, guard against buffer overflow.
9159 * src/z80/gen.c (aopGet): generate better code for sfr banked read
9161 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9163 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
9164 changed interrupt vector table generation to only emit declared vectors.
9165 * device/include/Makefile.in: added missing backslash
9166 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)

9170 Mainly changes to support compilation of the device libraries
9171 * src/pic16/device.c: stack is allocated via symbol and not
9172 via literal number. The symbol is placed in the corresponding
9173 position of the data ram
9174 * (pic16_dump_section): relocatable and absolute uninitialized
9175 data are now emitted in sorted order to reduce section naming,
9176 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
9177 weren't marked as being in the access bank,
9179 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
9181 Added portion of GNU PIC Library under the directory
9182 device/include/pic16 and device/lib/pic16. These files
9183 contain the declarations of SFRs for the PIC18Fxx2 devices.
9184 The directory is initialized via configure from toplevel.
9186 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
9188 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
9189 the spilllocations to be compared correctly
9191 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
9193 * src/SDCCast.c (decorateType): fixed bug introduced today
9195 2004-01-12 Borut Razem <borut.razem AT siol.net>

9202 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
9203 in simpler and even better code
9205 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
9207 * src/SDCCicode.c (operandOperation): fixed bug #874819

9211 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9213 * doc/sdccman.lyx: Moved and added some sections, small changes
9214 all over. Telling LaTeX to be less strict with word spacing
9215 to better keep the right margin. Changed some notes about
9216 maintainance of the ports in section 3.2.1 - is it OK like this?
9218 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
9220 SDCC source changes:
9221 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

9255 UPPER for immediate operands,
9256 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
9258 * src/pic16/peeph.def: all peepholes with movff are commented out,
9259 because there is a problem in the pcode peep optimizer,
9260 * src/pic16/ralloc.c: the register allocator can now reuse local
9261 function symbols for another function. This saves register usage.
9262 * src/pic16/ralloc.h: added flag isLocal in structure regs,
9264 Added file src/pic16/NOTES with information about program writing on
9265 the current port version.

9274 * src/SDCCmain.c : fixed #872250: -l command line defined library
9275 files are scanned before standard library files
9277 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9294 gen51Code): more efficient parameter receive for --model-large
9297 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9300 * src/z80/main.c: added missed needLinkerScript flags (more than
9301 one port structure defined in these file)
9302 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

9318 needLinkerScript flag
9320 * src/pic16/gen.c (genAddrOf): fixed bug #863624
9321 * src/pic/glue.c: added variable udata_section_name to
9322 override default uninitialized data segment definition for
9323 devices only with SHAREBANK memory (reported from Erik Epetrich)
9324 * (pic14emitOverlay): modified to emit a commented overlay segment
9325 directive when no overlay data exist
9326 * (picglue): modified to emit uninitialized data segment
9327 according to udata_section_name

9333 * src/pic16/main.c: added $l in _asmCmd, changed extension for
9334 object file from '.rel' to '.o' in port->linker structure,
9335 changed size of fptr from 2 to 3 in port structure
9337 2004-01-07 Borut Razem <borut.razem AT siol.net>
9339 * support/scripts/sdcc.nsi: update PATH
9340 * support/scripts/sdcc.ico: craeted
9342 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>

9353 include information about variables allocated to the overlay
9356 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9358 * as/mcs51/lkmain.c: Help about -Y option

9370 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9372 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
9373 (default behaviour).
9375 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9377 A python script to validate compiler diagnostic messages. It can be
9378 used to verify that sdcc complains about bad c source code and
9379 gives a good location of the error.
9380 * support/valdiag/Makefile,
9381 * support/valdiag/valdiag.py,
9382 * support/valdiag/tests/*
9384 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9397 * src/common.h: added ifndef/define/endif macros
9398 around the header file.
9399 Bug reported from Jesus Calvino-Fraga
9401 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
9403 * sdcc.spec: updated
9404 * device/include/Makefile.in: don't install CVS directories
9405 * device/lib/Makefile.in: added removal of CVS directories after install
9406 * doc/Makefile: fixed install, added local_icons
9407 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
9408 * src/mcs51/gen.c (genRightShift): fixed bug #870788
9409 * src/ds390/gen.c (genRightShift): fixed bug #870788
9410 * src/SDCCast.c (decorateType): fixed bug #870781
9412 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9414 PIC16 port related changes:
9415 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
9416 added variable stackPos,
9418 * gen.c: genCall, assignResultValue: added support for
9419 pushing/retrieving function parameters to/from stack,
9420 genFunction,genEndFunction: setup stack frame for the
9422 genAddrOf: will be changed according to bug 863624
9424 * added files genutils.c and genutils.h which contain gen*
9425 debugged and optimised functions extracted from gen.c
9427 * glue.c: added variable 'externs' which holds extern symbols,
9428 pic16emitRegularMap: is modified to properly handle relocatable
9429 symbols under the new scheme,
9430 pic16createInterruptVect: is modified
9431 pic16printPublics: is modified to emit 'global' assembler directives,
9432 added pic16_printExterns to print extern symbols,
9433 pic16glue: initializes stack/frame pointer in the beginning of
9434 the assembly output. Temporary hack, will be corrected later,
9435 because gplink yet does not support stack and SDCC does not
9436 yet support a type of crt0.o object to create the final binary.
9438 * Removed many lines that contain 8051 legacy code.
9439 * The code is finally placed under a 'code' directive.
9440 * Added port specific options.
9442 * _process_pragma: simplified since now we do not need *special*
9443 include file to define SFR registers. But a separate header
9444 will be needed. This will be developed later.
9445 * _pic16_parseOptions: added, parses port specific options:
9446 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9447 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9448 --preplace-udata-with=
9450 * _pic16_setDefaultOptions: modified to initialize section names,
9451 but hack is temporarly out of order since it needs improvement.
9452 * _pic16_genAssemblerPreamble: configuration words are emitted by
9453 their address instead of their name. This part is incomplete and
9454 supports only the 18Fxx2 devices. Other devices will emit an error
9455 during assembly since they do not contain the same set of config
9457 * _pic16_genIVT: is modified,
9459 * pcode.c: added definitions for some hardware registers that are needed
9461 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9462 All PCI entries are updated. Now LFSR is supported.
9463 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9464 * added pic16_newpCodeOpLit2 to support instructions with
9465 two literal arguments
9466 * pic16_pCode2str: corrected code that emits assembler instructions
9467 with two literal operands and those that have an access bit modifier
9468 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9469 this fixes a bug which caused some labels to be lost, when an
9470 assembler directive was added, i.e. banksel,
9471 * pic16_FixRegisterBanking: improved logic that causes the insertion
9473 * InlineFunction: functions that are called once, are not any more
9474 inlined. This can be a port option in the future,
9476 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9478 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9479 hold the corresponding uninitialized symbols,
9480 * pic16_allocProcessorRegister: registers have explicit marked the
9482 * pic16_allocInternalRegister: registers are explicit marked as
9484 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9485 processing list, so bit registers were lost,
9488 * ralloc.h: added field 'accessBank' and original symbol operand
9489 in register definition,
9490 * removed the field isMapped from register definition,
9492 ** Several functions have been removed from various sources:
9493 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9494 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9495 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9496 pic16_assignRelocatableRegisters
9498 ** others have been introduced:
9499 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9500 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9502 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9504 * support/scripts/inc2h.pl: changed definition of BIT_AT
9505 to emit 'sbit at' instead of 'bit at'. This was a request.
9507 PIC16 port related preliminary changes:
9508 * gen.c: prefixed function popRegFromString with
9509 pic16_ and all references to it corrected
9510 * pcode.c: all pic16_pc_* hardware registers prefixed
9511 with underscore (_),
9512 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9513 * ralloc.c: newReg(): when register is REG_SFR then
9514 set address to rIdx,
9515 pic16_allocProcessorRegister(): marks register wasUsed=0
9516 pic16_writeUsedRegs(): added a call to assign processor
9517 registers via pic16_assignFixedRegisters
9519 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9521 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9522 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9523 variables in unused register banks. Also the SSEG is placed
9524 wherever there is enough space for it, and IDATA can be anywhere
9525 in internal RAM. For now compile using -Wl-Y[stack_size].
9526 The mem file is different for this option as well, since it
9527 makes no sense of talking about DSEG lenght.
9529 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9531 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9532 in certain cases, e.g. when ROM assignment, patch provided
9533 from Albert den Haan.
9535 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

10088 not occur if the control variable is involved with a
10089 relational operator.

10554 these ports have their own __sdcc_external_start()
10556 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
10558 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10559 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10560 type for bits was changed. It resulted in bit variables becoming
10561 global, which is not permitted in PIC 14 assembly output.
10563 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10565 * doc/sdccman.lyx: various additions and updates. Rearranged sections
10567 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10569 Z80 and MCS51 linkers complaint if a public symbol is defined
10570 in more than one library module:
10574 * as/mcs51/Makefile.in

10578 A few small changes that speed up the peephole optimizer.
10582 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10584 Try to make the peephole optimizer smarter by maintaining
10585 an association between the assembly source code and the
10586 iCodes that originated them. Put this information to use
10587 with a new peephole rule condition "notVolatile" so that
10588 the rules can be aggressive yet still safe.
10593 * src/mcs51/peeph.def
10595 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10599 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10600 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10601 if the left or right operand symbols have the accuse flag set.
10603 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10605 Changed the type of the result of the ! (NOT) operator to char;
10606 previously it returned the same type as the source. This allows
10607 us to eliminate all the genFloatNot functions (all of its target
10608 implementations were very buggy) since !float can use the same
10611 * src/SDCCicode.c (ast2iCode): ! returns char
10612 * src/mcs51/gen.c (genNot, genNotFloat),
10613 * src/ds390/gen.c (genNot, genNotFloat),
10614 * src/z80/gen.c (genNot, genNotFloat),
10615 * src/pic/gen.c (genNot, genNotFloat),
10616 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

10620 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10621 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10622 during interrupts. Ensure WSAVE is located at a shared bank address.
10623 2. Fixed page selection in some places
10624 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10625 the registers name strings.
10626 4. Fixed "signed / unsigned compare" compiler warnings.
10627 5. The PIC port manages its own allocation of the general purpose
10628 registers, but makes no attempt to reuse them. As a result when
10629 compiling it soon runs out of general purpose registers. Some
10630 additional code was added to the files pcode.c and device.c to walk
10631 through the function call tree and rename the registers so that they
10641 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10642 genPlus() & genMinus() when the result is the same as left or right
10644 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10648 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10650 Made bitfield a distinct type from bit so that bitfields
10651 convert as per ANSI C and bits retain their traditional
10652 boolean style behaviour. Implemented bitfield support in
10660 * src/ds390/gen.c: bit v bitfield split
10661 * src/z80/gen.c: New support for bitfields
10662 * support/regression/tests/bitfields.c: reenabled z80,
10665 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10667 Rules 246.x, 247.x relate to bitfields, the others speed up
10668 access to xdata mapped I/O devices.
10670 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
10672 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10674 Cleaned up genPackBits and genUnpackBits and added two helper
10675 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
10676 for literal assignments in genPackBits (thanks to Frieder for
10682 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10684 Fixed bug #748310 (pointer to function type mishandled when the
10685 function name is omitted). Also fixed a SIGSEGV when a function
10686 attribute (reentrant, etc) is used on a non-function or on a
10687 function but misplaced before the parameter list.
10689 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
10691 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
10692 * support/Util/SDCCerr.h,
10693 * support/Util/SDCCerr.c: Added func attr misuse error msg
10695 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
10697 Fixed bug #787649 by anonymous
10698 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
10699 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
10701 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10703 Fixed numerous bitfield problems.
10705 * src/SDCC.y: More bitfield related error checking

10712 * support/regression/tests/bitfields.c: tests added
10714 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10716 Made the constant following the "interrupt" keyword optional. If
10717 omitted, the function will not automatically be given an entry
10718 in the interrupt vector table (similar to #pragma NOIV, but
10719 less syntacticly kludgy). The interrupt number is also now
10720 range checked. Also fixed a bug in the high order bit example
10727 * support/Util/SDCCerr.c
10728 * support/Util/SDCCerr.h
10731 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

10734 * src/SDCCicode.c (operandOperation): rewritten some ops
10735 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
10736 * src/SDCCsymt.c (computeType): literals are handled the same way as any
10738 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
10739 be re-activated by defining REDUCE_LITERALS)
10740 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
10741 unsigned, but are signed by default
10742 * src/SDCCval.c (constVal): rearranged
10743 * src/SDCCval.c (valMod): preliminary fix
10744 * src/SDCCval.c (valCastLiteral): use TYPE_* types

10784 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
10785 * src/SDCCval.c (constVal): changed default to signed; hex and octal
10786 constants are unsigned; added recognition of "u" flag for unsigned
10787 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
10788 * src/SDCCval.c (valDiv, valMod): fixed signdness

11196 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
11197 the regression tests I'm not brave enough to enable 245.b, 245.c
11198 * doc/sdccman.lyx: added latex preamble for hyperref package.
11199 Using pdflatex this will give you a hyperlinked pdf file with
11200 bookmarks. (prepend '%' before /usepackage if this breaks something)

11250 added if/endif conditional macros to remove options help
11251 messages from optionsTable when a port is not configured, added
11252 support for the PIc16 port in the ports table, when executing
11253 the compiler with no port specified on command line, a default
11254 port is selected with the new macro DEFAULT_PORT which is
11255 defined in port.h, in setDefaultOptions() linkOptions is removed
11256 from initialization assignment, since now it is a set,
11257 parseCmdLine uses setParseWithComma for linkOptions, in
11258 linkEdit() linkOptions are accessed with new function indexSet()
11259 which returns the i'th item of a set variable. See SDCCset.c, in
11260 linkEdit() when calling buildCmdLine(), added linkOptions as
11261 last argument. Now users can pass arguments to gplink via the
11262 -Wl option, main() uses pic16glue() to glue up pic16 programs

11274 * src/pic16/glue.c: commented out some error producing lines
11275 * src/pic16/main.c: __config directives are commented out to stop
11276 gpasm complaining and test the linkage with gplink, _linkCmd and
11277 _asmCmd changed to be more gplink and gpasm friendly
11278 * src/pic16/peeph.def: peep rule 3 is commented out, since it
11279 produced an error when parsed, peep rule 12 is added to utilize
11280 movff, but it is commented out since the pCode does not support
11281 yet a command with 2 address arguments
11283 2003-05-18 <johan AT balder>
11285 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

12386 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12387 Changes to aslink (All the changes are marked with 'JCF'):
12389 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
12392 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
12393 area BSEG. Also moves, if possible, the DATA area down into the internal
12394 ram so more space is available.
12396 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
12399 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
12400 not bytes. Function summary() which creates a memory usage summary
12401 file with extension .mem. Reports of overlaping stack and small stack
12402 size. If the space for the stack is less than 16 bytes aslink trows a
12405 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
12406 the 8051. Option 'y' for memory summary output file.
12408 Changes to sdcc (All the changes are marked with 'JCF'):
12410 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
12412 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
12413 overlaying area for it (uses RegBankUsed[4]).
12415 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
12416 bank zero as used by default. By default aslink locates the stack
12417 (equivalent to --stack-after-data). Pass option 'y' to aslink for
12418 the creation of the .mem file. Delegates the allocation of data area
12419 to aslink (it is not longer 0x30 by default). If --stack-loc passes
12420 the begining of the stack area to aslink.
12422 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
12423 glue() in SDCCglue.c creates an area for it.
12425 2002-09-03 Borut Razem <borut.razem AT siol.net>
12426 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12427 sdcc/src/pic/glue.c:
12428 introduced atexit() handler for teporay files removal in case of
12429 errors, assertions, ...
12431 2002-08-29 Borut Razem <borut.razem AT siol.net>
12432 * sdcc/support/cpp2/auto-host_vc_in.h:
12433 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12434 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12435 Maybe there is a similar problem with BORLANDC? It should be checked!
12437 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12438 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12439 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12440 was not executed, and the compiler (cl) launched a warning:
12441 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12443 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12444 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
12446 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
12447 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
12449 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12450 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
12451 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
12452 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12453 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
12454 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
12455 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
12456 - added Release configuration in VS projects
12457 - review of compiler an linker options
12458 - VC .exe files are generated in bin_vc directory, not to interfere
12459 with binaries generated from other projects (cygwin, mingw, bcc ...)
12461 * sdcc/src/yacc.dsp: added
12463 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12464 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12465 and insert the version number definitions from .version
12467 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12469 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
12470 added - genarate auto-host.h using auto-host_vc_in.h as template
12473 removed from CVS, generated automatically
12475 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
12476 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12478 2002-08-11 Borut Razem <borut.razem AT siol.net>
12479 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12481 2002-08-10 Borut Razem <borut.razem AT siol.net>
12482 * src/SDCCmain.c (main):
12483 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12484 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12485 The consequence was that some temporary files were not removed.
12488 unification of code in functions tempfilename() and tempfile():
12489 function tempnam() is defined in Visual Studio 6.0 and .NET
12491 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
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 - removed compiler command line option /WX: Treats all warnings as errors
12496 - update a list of source files, included into the project
12498 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12499 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12500 changed project type to Generic Project so that can be correcly converted to VS.NET project
12502 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12504 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
12506 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
12508 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12509 added return 0 statements after assert() to make compiler happy
12511 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12512 added newline in the def file to keep MSC compiler satisfied
12514 * sdcc/src/z80/gen.c:
12515 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
12516 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
12517 - solved MSC error in function aopDump()
12519 * sdcc_vc.h: define PREFIX as "\\sdcc"
12521 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
12522 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

12559 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
12561 2002-03-28 Johan Knol <johan AT balder>
12563 * src/SDCCval.c: fixed bug #532436
12565 2002-03-14 Scott Dattalo <scott AT dattalo.com>

12570 Added -p option. Allows port dependent processor to be specified.
12573 Initialized the new field char *Processor field to NULL in all ports
12576 Compiler generated registers for interrupt context saving
12577 were not getting allocated.
12579 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
12582 Fixed left shift. Will promote the left side of a left shift
12583 if a) left shifting more than size of operand or b) when assigned
12584 to something size > size of left side

12694 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
12696 * sdcc/src/SDCCloop.c:
12697 Previous fix was not good. basic blocks that have "break" or "return" are
12698 not really partof a loop , but live ranges used in these blocks should
12699 be live thru the entire loop, so set partOfLoop but don't add them to
12702 2002-02-21 <johan AT FRIJA>
12704 * src/SDCCcse.c: fixed bug #514308
12706 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
