2209 on rIfx (genCmp was broken)
2211 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2213 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
2214 * src/z80/main.c (_keywords[]),
2215 * src/SDCCglobal.h (struct options),
2217 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
2218 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
2219 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
2220 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
2221 always available in leading double underscore form. The C99 support is
2222 mostly missing, but it's a start.
2223 * support/regression/tests/bug-227710.c: fixed nonconforming use of
2224 reserved identifier "__data".
2226 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
2228 * src/mcs51/peeph.def: fixed bug 1170013

2270 immedDom() returning wrong block; probably fixes bug #1160833)
2272 2005-03-20 Borut Razem <borut.razem AT siol.net>
2274 * support/scripts/inc2h.pl: WIN32 port
2276 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
2278 * device/lib/makefile.in: added abs.c and labs.c
2280 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
2282 * device/include/stdint.h: added
2283 * device/lib/abs.c: added

2302 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2304 * device/lib/printf_large.c: removed inline assembly for portability and
2305 readability. Use printf_fast if speed or size are more important.
2306 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2307 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2309 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2311 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2312 prevent compiler warning
2314 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2316 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2317 moved to level 0 and declared as static. Also they are explicit
2318 placed in access bank. This was necessery because some times they
2319 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2320 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2321 optimizations. Currently only compare to unsigned char is implemented,
2322 * src/pic16/gen.c: added fReturnIdx array,
2323 * (struct resolvedIfx) is moved to gen.h and made public,
2324 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2325 * (aopForSym): added an optimization to directly store in stack of
2326 the operand of a SEND iCode,
2327 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2328 but as registers instead (AOP_REG) using the fReturnIdx array,
2329 * (pic16_freeAsmop): remove the freed register from the
2330 _G.sregsAlloc field,
2331 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2332 a compare of 'WREG',
2333 * (pic16_popGetTempRegCond): changed function prototype, now
2334 function takes also a bitVector argument v which holds the current
2335 set of registers that are allocated for stack access by aopForSym,
2336 registers allocated in aopForSym for accessing stack symbols are not
2337 any more part of the functions usedRegs field,
2338 * (genCall): some times aopOp is called for a stack variable to be
2339 send, aopForSym might perform the push, if this is true make sure
2340 that genCall doesn't push the variable twice by testing _G.resDirect,
2341 * (genFunction): changed testing for unspecified interrupt number
2342 from 256 to INTNO_UNSPEC,
2343 * modified selection scheme of frame pointer generation. Previously
2344 if function did use local registers a frame pointer was generated,
2345 now a frame pointer is generated only if function has arguments
2346 (that need PLUSW2 register access), or has stack arguments, or the
2347 compiler is not instructed to omit the frame pointer,
2348 * (genEndFunction): before restoring local registers that were saved
2349 in the function preamble, also restore the registers that *might*
2350 have been allocated for stack access,
2351 * (genRet): removed some old comments,
2352 * (genCmp, the active (RN's) version): added a call to the
2353 pic16_genCmp_special function to perform the compare with a more
2354 robust and optimized way,
2355 * (genInline): a feature has been added in inline code generation,
2356 which allows a wildcard variable substitution when writing inline
2357 assembly. Code is incomplete and experimental therefore undocumented,
2358 * (genCast): changed order of aopOp for result and right to allow
2359 aopForSym to directly load the result if possible,
2360 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2361 perform an optimized compare on some selected special occasions,
2362 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2363 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2364 generate an IVT any more,
2365 * src/pic16/main.c (pic16_optionsTable): added command line option
2367 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2368 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2370 * src/pic16/NOTES: Raphael Neider added in list of active developers
2371 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2372 jumptable_end to prevent bug #,
2373 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2374 inCond and outCond fields,
2375 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2376 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2377 turn off register spilling,
2378 * (packRegsForOneUse): synced with other ports' versions although it
2379 is not used currently,
2380 * (pic16_packRegisters): added an optimization while reading
2381 structure bitfields, some registers may be saved (malloc code is
2382 decreased by 80 bytes)
2384 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2386 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2387 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2388 this can be optimized more?
2390 2005-03-10 Raphael Neider <rneider AT web.de>
2392 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2393 genNearPointerGet): (hopefully) fixed access to bitfields via
2394 pointers (p->bitN = x; and x = p->bitN; failed)
2396 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
2398 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

2439 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
2440 to keep the correct label reference count when adding/removing references
2441 to labels. A peephole file using this is appended to patch #1144962.
2443 2005-02-14 Raphael Neider <rneider AT web.de>

2573 * src/pic16/main.c (_process_pragma): fixed another malloc bug
2574 (sizeof(sectNames) changed to sizeof(sectName))
2575 Both patches fix segfaults under MinGW.

2581 * src/pic16/gen.c (pic16_aopOp,pic16_popGet): added handling
2582 of (byte sized) temporaries (assign them to WREG for now)
2583 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
2584 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
2585 this might fix SIGSEGVs on MinGW...
2586 * src/SDCCopt.c (killDeadCode): restored original behaviour
2587 (volatile operands might get thrown away though)
2589 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
2591 * src/pic16/gen.c: fixed bug #1106975,

2596 * added function attribute 'shadowregs' to take advantage of shadow
2598 * added function attribute 'wparam' as an alternative to the wparam
2600 * support/Utils/SDCCerr.[ch]: added error E_SHADOWREGS_NO_ISR when
2601 user declares a non-ISR function as 'shadowregs',

3030 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3031 Now 4 algorithms for mcs51 jumptable generation are used:
3032 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3033 addresses loaded pc-relative for up to 112 cases and stack-pushing
3034 target addresses loaded with offset from dptr for up to 256 cases.
3036 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
3037 * src/mcs51/main.c: adapted constants for switch table generation
3038 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp
3040 2004-11-26 Maarten Brock <sourceforge.brock AT dse.nl>
3042 * device/lib/printf_large.c (_print_format): fixed bug 1073386
3043 * support/regression/tests/bug1057979.c: added test for bug 1073386
3045 2004-11-25 Vangelis Rokas <vrokas AT otenet.gr>
3047 * src/pic16/pcode.c: fixed bug which may produce error in non-GNU
3050 2004-11-25 Vangelis Rokas <vrokas AT otenet.gr>
3052 * src/pic16/device.h,
3053 * src/pic16/genarith.c,
3056 * src/pic16/pcode.c: applied patches #1068154 and #1070213
3058 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
3060 Large cummulative patch for pic16 port.
3061 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
3062 to call when a stack overflow occurs,
3063 * (malloc.h): added CVS Id tag,
3064 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3066 * added libc directory. The current version of LibC contains string
3067 functions, ctype functions and macros and some functions of the
3068 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3069 be extensively tested in the future. Standard disclaimer here.
3070 Library is not automatically build yet. But one can build it by
3071 invoking 'make' inside the libc directory.
3072 * added ADC library under libio. Preliminary version yet.
3074 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
3075 * src/pic16/gen.c (aopForRemat): asmop size is filled by
3076 aopForRemat() now and not by pic16_aopOp(),
3077 * (pic16_popGetTempReg): removed warning messgae when allocating
3078 temporary registers, its a buggy feature and will be removed,
3079 * (pic16_popGet): set register instance field in AOP_CRY,
3080 * (pic16_outBitC): fixed for results in size greater than 1,
3081 * (genUminusFloat): fixed for pic16, ported code from mcs51,
3082 * (pic16_storeForReturn): optimized return of 0,
3083 * (genCmp): experimental code for new genCmp which uses PIC18's
3084 special compare&skip instructions. Initial tests fail some times
3085 with variables grater than 1 byte in size, so new code is disabled,
3086 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3088 * (genCast): began a fix to optimize the casting of a bit to another
3089 bit, now assigning a bitfield to another bitfield will fail, sorry,
3090 * src/pic16/main.c: disabled the use of lr-support feature,
3091 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
3092 * added some function prototypes, added function _debugf prototype,
3093 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
3094 bits with offset (case PO_GPR_BIT),
3095 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
3097 * (isBankInstruction): modified to return 0 for no banking instruction,
3098 and 1 for banking instruction,
3099 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3100 caused stop processing pCodes after a inline assembly block,
3101 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
3102 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
3103 registers when it shouldn't,
3104 * src/pic16/ralloc.c (allocReg): add preliminary support for
3105 supporting a limited set of temporary registers,
3107 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3109 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
3110 genDataPointerSet): ensure assignments always copy in MSB to LSB
3112 (loadRegFromAop): recognize CLRH optimization,
3113 (genFunction): optimize RECEIVE iCodes in reentrant functions
3115 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3117 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
3118 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
3120 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

3131 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
3133 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

6115 loaded with the linker search paths (-L arguments) and the libraries
6116 to be linked with the current source (-l arguments). Changes
6117 currently will affect only the pic16 port.
6118 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6119 include path the port specific paths and port specific libraries,

6138 Documenting changes from previous commits.
6139 * configure.in (version 1.56),
6140 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6141 when generating output files to configure the pic16 library,
6142 but now I've commented it out, since gputils aren't installed in the
6143 SF compile farm, so library won't compile
6145 * device/lib/Makefile.in (version 1.56): initially I've added in
6146 target 'all' the prerequestive 'model-pic16' so it compiled the
6147 pic16 library, but now I've commented it out for the same reasons
6149 * added targets 'model-pic16' and 'objects-pic16' to compile the
6151 * added target 'port-specific-objects-pic16' to handle the
6152 generated libraries and copy them into the build/ directory
6153 * added target 'clean-intermediate-pic16' to clean intermediate
6154 files into pic16 directory
6155 * in target 'installdirs' added line to create directory pic16 in
6156 the installation path
6158 * device/include/Makefile.in (version 1.11): in target 'install'
6159 added lines to copy all header files to installation path,
6160 * in target 'installdirs' added line create directory for pic16
6161 headers in the installation path
6163 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

6176 * src/z80/main.c (_parseOptions): fixed the portmode= command line
6177 option so that it actually works. Made it specific to the z80, since
6178 the gbz80 doesn't have these kinds of I/O ports.
6180 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6182 * device/include/z180.h,

6195 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6197 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
6198 changed interrupt vector table generation to only emit declared vectors.
6199 * device/include/Makefile.in: added missing backslash
6200 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)

6204 Mainly changes to support compilation of the device libraries
6205 * src/pic16/device.c: stack is allocated via symbol and not
6206 via literal number. The symbol is placed in the corresponding
6207 position of the data ram
6208 * (pic16_dump_section): relocatable and absolute uninitialized
6209 data are now emitted in sorted order to reduce section naming,
6210 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6211 weren't marked as being in the access bank,
6213 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6215 Added portion of GNU PIC Library under the directory
6216 device/include/pic16 and device/lib/pic16. These files
6217 contain the declarations of SFRs for the PIC18Fxx2 devices.
6218 The directory is initialized via configure from toplevel.
6220 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
6222 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
6223 the spilllocations to be compared correctly

6247 * doc/sdccman.lyx: Moved and added some sections, small changes
6248 all over. Telling LaTeX to be less strict with word spacing
6249 to better keep the right margin. Changed some notes about
6250 maintainance of the ports in section 3.2.1 - is it OK like this?
6252 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

6289 UPPER for immediate operands,
6290 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
6292 * src/pic16/peeph.def: all peepholes with movff are commented out,
6293 because there is a problem in the pcode peep optimizer,
6294 * src/pic16/ralloc.c: the register allocator can now reuse local

6296 * src/pic16/ralloc.h: added flag isLocal in structure regs,
6298 Added file src/pic16/NOTES with information about program writing on
6299 the current port version.

6331 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6334 * src/z80/main.c: added missed needLinkerScript flags (more than
6335 one port structure defined in these file)
6336 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

6352 needLinkerScript flag
6354 * src/pic16/gen.c (genAddrOf): fixed bug #863624
6355 * src/pic/glue.c: added variable udata_section_name to
6356 override default uninitialized data segment definition for
6357 devices only with SHAREBANK memory (reported from Erik Epetrich)
6358 * (pic14emitOverlay): modified to emit a commented overlay segment
6359 directive when no overlay data exist
6360 * (picglue): modified to emit uninitialized data segment
6361 according to udata_section_name

6371 2004-01-07 Borut Razem <borut.razem AT siol.net>
6373 * support/scripts/sdcc.nsi: update PATH
6374 * support/scripts/sdcc.ico: craeted

6387 include information about variables allocated to the overlay
6390 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6392 * as/mcs51/lkmain.c: Help about -Y option

6404 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6406 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6407 (default behaviour).
6409 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6411 A python script to validate compiler diagnostic messages. It can be
6412 used to verify that sdcc complains about bad c source code and
6413 gives a good location of the error.
6414 * support/valdiag/Makefile,
6415 * support/valdiag/valdiag.py,
6416 * support/valdiag/tests/*

6433 Bug reported from Jesus Calvino-Fraga
6435 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6437 * sdcc.spec: updated
6438 * device/include/Makefile.in: don't install CVS directories
6439 * device/lib/Makefile.in: added removal of CVS directories after install
6440 * doc/Makefile: fixed install, added local_icons
6441 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6442 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6443 * src/ds390/gen.c (genRightShift): fixed bug #870788
6444 * src/SDCCast.c (decorateType): fixed bug #870781
6446 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6448 PIC16 port related changes:
6449 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6450 added variable stackPos,
6452 * gen.c: genCall, assignResultValue: added support for
6453 pushing/retrieving function parameters to/from stack,
6454 genFunction,genEndFunction: setup stack frame for the
6456 genAddrOf: will be changed according to bug 863624
6458 * added files genutils.c and genutils.h which contain gen*
6459 debugged and optimised functions extracted from gen.c
6461 * glue.c: added variable 'externs' which holds extern symbols,
6462 pic16emitRegularMap: is modified to properly handle relocatable
6463 symbols under the new scheme,
6464 pic16createInterruptVect: is modified
6465 pic16printPublics: is modified to emit 'global' assembler directives,
6466 added pic16_printExterns to print extern symbols,
6467 pic16glue: initializes stack/frame pointer in the beginning of
6468 the assembly output. Temporary hack, will be corrected later,
6469 because gplink yet does not support stack and SDCC does not
6470 yet support a type of crt0.o object to create the final binary.
6472 * Removed many lines that contain 8051 legacy code.
6473 * The code is finally placed under a 'code' directive.
6474 * Added port specific options.
6476 * _process_pragma: simplified since now we do not need *special*
6477 include file to define SFR registers. But a separate header
6478 will be needed. This will be developed later.
6479 * _pic16_parseOptions: added, parses port specific options:
6480 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6481 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6482 --preplace-udata-with=
6484 * _pic16_setDefaultOptions: modified to initialize section names,
6485 but hack is temporarly out of order since it needs improvement.
6486 * _pic16_genAssemblerPreamble: configuration words are emitted by
6487 their address instead of their name. This part is incomplete and
6488 supports only the 18Fxx2 devices. Other devices will emit an error
6489 during assembly since they do not contain the same set of config
6491 * _pic16_genIVT: is modified,
6493 * pcode.c: added definitions for some hardware registers that are needed
6495 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6496 All PCI entries are updated. Now LFSR is supported.
6497 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6498 * added pic16_newpCodeOpLit2 to support instructions with
6499 two literal arguments
6500 * pic16_pCode2str: corrected code that emits assembler instructions
6501 with two literal operands and those that have an access bit modifier
6502 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6503 this fixes a bug which caused some labels to be lost, when an
6504 assembler directive was added, i.e. banksel,
6505 * pic16_FixRegisterBanking: improved logic that causes the insertion
6507 * InlineFunction: functions that are called once, are not any more
6508 inlined. This can be a port option in the future,
6510 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6512 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6513 hold the corresponding uninitialized symbols,
6514 * pic16_allocProcessorRegister: registers have explicit marked the
6516 * pic16_allocInternalRegister: registers are explicit marked as
6518 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6519 processing list, so bit registers were lost,
6522 * ralloc.h: added field 'accessBank' and original symbol operand
6523 in register definition,
6524 * removed the field isMapped from register definition,
6526 ** Several functions have been removed from various sources:
6527 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6528 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6529 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6530 pic16_assignRelocatableRegisters
6532 ** others have been introduced:
6533 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6534 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6536 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6538 * support/scripts/inc2h.pl: changed definition of BIT_AT
6539 to emit 'sbit at' instead of 'bit at'. This was a request.
6541 PIC16 port related preliminary changes:
6542 * gen.c: prefixed function popRegFromString with
6543 pic16_ and all references to it corrected
6544 * pcode.c: all pic16_pc_* hardware registers prefixed
6545 with underscore (_),
6546 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6547 * ralloc.c: newReg(): when register is REG_SFR then
6548 set address to rIdx,
6549 pic16_allocProcessorRegister(): marks register wasUsed=0
6550 pic16_writeUsedRegs(): added a call to assign processor
6551 registers via pic16_assignFixedRegisters
6553 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6555 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6556 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6557 variables in unused register banks. Also the SSEG is placed
6558 wherever there is enough space for it, and IDATA can be anywhere
6559 in internal RAM. For now compile using -Wl-Y[stack_size].
6560 The mem file is different for this option as well, since it
6561 makes no sense of talking about DSEG lenght.
6563 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6565 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6566 in certain cases, e.g. when ROM assignment, patch provided
6567 from Albert den Haan.
6569 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7620 iCodes that originated them. Put this information to use
7621 with a new peephole rule condition "notVolatile" so that
7622 the rules can be aggressive yet still safe.
7627 * src/mcs51/peeph.def
7629 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7633 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7634 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7635 if the left or right operand symbols have the accuse flag set.
7637 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7639 Changed the type of the result of the ! (NOT) operator to char;
7640 previously it returned the same type as the source. This allows
7641 us to eliminate all the genFloatNot functions (all of its target
7642 implementations were very buggy) since !float can use the same
7645 * src/SDCCicode.c (ast2iCode): ! returns char

7654 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7655 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7656 during interrupts. Ensure WSAVE is located at a shared bank address.
7657 2. Fixed page selection in some places
7658 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7659 the registers name strings.
7660 4. Fixed "signed / unsigned compare" compiler warnings.
7661 5. The PIC port manages its own allocation of the general purpose
7662 registers, but makes no attempt to reuse them. As a result when
7663 compiling it soon runs out of general purpose registers. Some
7664 additional code was added to the files pcode.c and device.c to walk
7665 through the function call tree and rename the registers so that they
7675 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

7682 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7684 Made bitfield a distinct type from bit so that bitfields
7685 convert as per ANSI C and bits retain their traditional
7686 boolean style behaviour. Implemented bitfield support in
7694 * src/ds390/gen.c: bit v bitfield split
7695 * src/z80/gen.c: New support for bitfields
7696 * support/regression/tests/bitfields.c: reenabled z80,
7699 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7701 Rules 246.x, 247.x relate to bitfields, the others speed up
7702 access to xdata mapped I/O devices.
7704 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7706 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7708 Cleaned up genPackBits and genUnpackBits and added two helper
7709 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7710 for literal assignments in genPackBits (thanks to Frieder for
7716 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7718 Fixed bug #748310 (pointer to function type mishandled when the
7719 function name is omitted). Also fixed a SIGSEGV when a function
7720 attribute (reentrant, etc) is used on a non-function or on a
7721 function but misplaced before the parameter list.

7748 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7750 Made the constant following the "interrupt" keyword optional. If
7751 omitted, the function will not automatically be given an entry
7752 in the interrupt vector table (similar to #pragma NOIV, but
7753 less syntacticly kludgy). The interrupt number is also now
7754 range checked. Also fixed a bug in the high order bit example

8211 Finalize muluint/mulsint and mululong/mulslong merging:
8212 * device/lib/_mulint.c
8213 * device/lib/_mullong.c
8214 * device/lib/gbz80/mul.s
8215 * device/lib/gbz80/stubs.s
8216 * device/lib/z80/mul.s
8217 * device/lib/z80/stubs.s
8218 * src/SDCCsymt.c (initCSupport)
8220 2003-05-25 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8222 * as/mcs51/lkaomf51.c: Address space 'z' was missing.
8223 * src/avr/avr.dsp, src/ds390/ds390.dsp, src/mcs51/mcs51.dsp,
8224 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
8225 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used
8228 2003-05-25 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8230 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
8231 the regression tests I'm not brave enough to enable 245.b, 245.c
8232 * doc/sdccman.lyx: added latex preamble for hyperref package.
8233 Using pdflatex this will give you a hyperlinked pdf file with
8234 bookmarks. (prepend '%' before /usepackage if this breaks something)
8236 2003-05-24 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

8246 * src/SDCCglue.c (printIval): fixed bug #739934
8248 2003-05-19 Bernhard Held <bernhard AT bernhardheld.de>
8250 Applied patch from bug 737905 (renamed yylineo to mylineno):
8257 * src/pic16/pcode.c: Cleaned warnings
8258 * src/pic16/pcodeflow.c: Cleaned warnings
8259 * src/pic16/pcoderegs.c: Cleaned warnings
8261 2003-05-19 Scott Dattalo <scott AT dattalo.com>
8263 * src/pic16/pcode.c: Cleaned warnings
8264 * src/pic16/pcodepeep.c: Cleaned warnings

8270 * src/pic16/pcode.c (pic16_get_op): fixed warning on alpha
8272 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
8274 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
8275 it can be defined with CFLAGS when running configure
8276 * src/SDCCmain.c: fixed compiling + linking with object files
8278 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
8280 * configure.in: configure for pic16 port,
8281 added --disable-pic16-port
8282 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
8283 * src/SDCCmain.c: linkOptions is changed to set *,
8284 added if/endif conditional macros to remove options help
8285 messages from optionsTable when a port is not configured, added
8286 support for the PIc16 port in the ports table, when executing
8287 the compiler with no port specified on command line, a default
8288 port is selected with the new macro DEFAULT_PORT which is
8289 defined in port.h, in setDefaultOptions() linkOptions is removed
8290 from initialization assignment, since now it is a set,
8291 parseCmdLine uses setParseWithComma for linkOptions, in
8292 linkEdit() linkOptions are accessed with new function indexSet()
8293 which returns the i'th item of a set variable. See SDCCset.c, in
8294 linkEdit() when calling buildCmdLine(), added linkOptions as
8295 last argument. Now users can pass arguments to gplink via the
8296 -Wl option, main() uses pic16glue() to glue up pic16 programs
8297 * src/SDCCpeeph.c: various changes to support pic16
8298 * src/SDCCset.c: added function void *indexSet(set *, int) to

8306 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
8308 * src/pic16/glue.c: commented out some error producing lines
8309 * src/pic16/main.c: __config directives are commented out to stop
8310 gpasm complaining and test the linkage with gplink, _linkCmd and
8311 _asmCmd changed to be more gplink and gpasm friendly
8312 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8313 produced an error when parsed, peep rule 12 is added to utilize
8314 movff, but it is commented out since the pCode does not support
8315 yet a command with 2 address arguments
8317 2003-05-18 <johan AT balder>
8319 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
8320 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT
8321 2003-05-17 Karl Bongers(apply patches from Martin Helmling)

8339 on entry now. Add tbreak. Other enhancements and fixes for use
8342 2003-05-12 Borut Razem <borut.razem AT siol.net>
8344 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
8346 2003-05-11 Borut Razem <borut.razem AT siol.net>
8348 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
8349 the path of bin directory, so that PATH is the only env. variable, which has to be set
8350 in case of standard installation.
8351 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

9354 * src/SDCCicode.c: fixed array add
9356 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
9357 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
9358 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9360 2003-01-04 <johan AT balder>
9362 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9364 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9365 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9367 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

9374 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
9375 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
9377 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9378 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9380 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9382 * in \sdcc\as\mcs51\ changed these files in order to create an
9383 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9384 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9385 following files to include the previous two files: aslink.dsp,
9386 Makefile.aslink, Makefile.bcc, and Makefile.in.
9388 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9389 .adb instead of .cdb
9391 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9393 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9394 value from option --iram-size.
9396 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9398 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9401 2002-09-18 <wiml AT hhhh.org>
9403 * SDCClrange.h: exposed setFromRange() and setToRange()
9404 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9405 packRegsForAccUse() (bug 542397)
9406 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9407 multiple times and emitting the fetch operations more than once
9408 added aopGetUsesAcc() function to allow binary operators to
9409 fetch their operands in the correct order; made genMinus() emit
9410 compact code for X = LITERAL - Y
9412 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9413 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9414 sprintf() in line 1267.
9416 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9417 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9420 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9421 Changes to aslink (All the changes are marked with 'JCF'):
9423 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9426 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9427 area BSEG. Also moves, if possible, the DATA area down into the internal
9428 ram so more space is available.
9430 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9433 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9434 not bytes. Function summary() which creates a memory usage summary
9435 file with extension .mem. Reports of overlaping stack and small stack
9436 size. If the space for the stack is less than 16 bytes aslink trows a
9439 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9440 the 8051. Option 'y' for memory summary output file.
9442 Changes to sdcc (All the changes are marked with 'JCF'):
9444 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9446 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9447 overlaying area for it (uses RegBankUsed[4]).
9449 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9450 bank zero as used by default. By default aslink locates the stack
9451 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9452 the creation of the .mem file. Delegates the allocation of data area
9453 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9454 the begining of the stack area to aslink.
9456 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9457 glue() in SDCCglue.c creates an area for it.
9459 2002-09-03 Borut Razem <borut.razem AT siol.net>
9460 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9461 sdcc/src/pic/glue.c:
9462 introduced atexit() handler for teporay files removal in case of
9463 errors, assertions, ...
9465 2002-08-29 Borut Razem <borut.razem AT siol.net>
9466 * sdcc/support/cpp2/auto-host_vc_in.h:
9467 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9468 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9469 Maybe there is a similar problem with BORLANDC? It should be checked!
9471 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9472 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9473 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9474 was not executed, and the compiler (cl) launched a warning:
9475 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9477 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9478 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9480 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9481 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9483 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9484 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9485 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9486 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9487 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9488 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9489 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9490 - added Release configuration in VS projects
9491 - review of compiler an linker options
9492 - VC .exe files are generated in bin_vc directory, not to interfere
9493 with binaries generated from other projects (cygwin, mingw, bcc ...)
9495 * sdcc/src/yacc.dsp: added
9497 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9498 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9499 and insert the version number definitions from .version
9501 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9503 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9504 added - genarate auto-host.h using auto-host_vc_in.h as template
9507 removed from CVS, generated automatically
9509 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9510 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9512 2002-08-11 Borut Razem <borut.razem AT siol.net>
9513 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9515 2002-08-10 Borut Razem <borut.razem AT siol.net>
9516 * src/SDCCmain.c (main):
9517 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9518 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9519 The consequence was that some temporary files were not removed.
9522 unification of code in functions tempfilename() and tempfile():
9523 function tempnam() is defined in Visual Studio 6.0 and .NET

9731 Previous fix was not good. basic blocks that have "break" or "return" are
9732 not really partof a loop , but live ranges used in these blocks should
