2196 on rIfx (genCmp was broken)
2198 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2200 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
2201 * src/z80/main.c (_keywords[]),
2202 * src/SDCCglobal.h (struct options),
2204 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
2205 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
2206 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
2207 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
2208 always available in leading double underscore form. The C99 support is
2209 mostly missing, but it's a start.
2210 * support/regression/tests/bug-227710.c: fixed nonconforming use of
2211 reserved identifier "__data".
2213 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

2259 2005-03-20 Borut Razem <borut.razem AT siol.net>
2261 * support/scripts/inc2h.pl: WIN32 port

2289 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2291 * device/lib/printf_large.c: removed inline assembly for portability and
2292 readability. Use printf_fast if speed or size are more important.
2293 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2294 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2296 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2298 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2299 prevent compiler warning
2301 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2303 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2304 moved to level 0 and declared as static. Also they are explicit
2305 placed in access bank. This was necessery because some times they
2306 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2307 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2308 optimizations. Currently only compare to unsigned char is implemented,
2309 * src/pic16/gen.c: added fReturnIdx array,
2310 * (struct resolvedIfx) is moved to gen.h and made public,
2311 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2312 * (aopForSym): added an optimization to directly store in stack of
2313 the operand of a SEND iCode,
2314 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2315 but as registers instead (AOP_REG) using the fReturnIdx array,
2316 * (pic16_freeAsmop): remove the freed register from the
2317 _G.sregsAlloc field,
2318 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2319 a compare of 'WREG',
2320 * (pic16_popGetTempRegCond): changed function prototype, now
2321 function takes also a bitVector argument v which holds the current
2322 set of registers that are allocated for stack access by aopForSym,
2323 registers allocated in aopForSym for accessing stack symbols are not
2324 any more part of the functions usedRegs field,
2325 * (genCall): some times aopOp is called for a stack variable to be
2326 send, aopForSym might perform the push, if this is true make sure
2327 that genCall doesn't push the variable twice by testing _G.resDirect,
2328 * (genFunction): changed testing for unspecified interrupt number
2329 from 256 to INTNO_UNSPEC,
2330 * modified selection scheme of frame pointer generation. Previously
2331 if function did use local registers a frame pointer was generated,
2332 now a frame pointer is generated only if function has arguments
2333 (that need PLUSW2 register access), or has stack arguments, or the
2334 compiler is not instructed to omit the frame pointer,
2335 * (genEndFunction): before restoring local registers that were saved
2336 in the function preamble, also restore the registers that *might*
2337 have been allocated for stack access,
2338 * (genRet): removed some old comments,
2339 * (genCmp, the active (RN's) version): added a call to the
2340 pic16_genCmp_special function to perform the compare with a more
2341 robust and optimized way,
2342 * (genInline): a feature has been added in inline code generation,
2343 which allows a wildcard variable substitution when writing inline
2344 assembly. Code is incomplete and experimental therefore undocumented,
2345 * (genCast): changed order of aopOp for result and right to allow
2346 aopForSym to directly load the result if possible,
2347 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2348 perform an optimized compare on some selected special occasions,
2349 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2350 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2351 generate an IVT any more,
2352 * src/pic16/main.c (pic16_optionsTable): added command line option
2354 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2355 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2357 * src/pic16/NOTES: Raphael Neider added in list of active developers
2358 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2359 jumptable_end to prevent bug #,
2360 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2361 inCond and outCond fields,
2362 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2363 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2364 turn off register spilling,
2365 * (packRegsForOneUse): synced with other ports' versions although it
2366 is not used currently,
2367 * (pic16_packRegisters): added an optimization while reading
2368 structure bitfields, some registers may be saved (malloc code is
2369 decreased by 80 bytes)
2371 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2373 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2374 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2375 this can be optimized more?
2377 2005-03-10 Raphael Neider <rneider AT web.de>
2379 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2380 genNearPointerGet): (hopefully) fixed access to bitfields via
2381 pointers (p->bitN = x; and x = p->bitN; failed)
2383 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
2385 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

2560 * src/pic16/main.c (_process_pragma): fixed another malloc bug
2561 (sizeof(sectNames) changed to sizeof(sectName))
2562 Both patches fix segfaults under MinGW.

2568 * src/pic16/gen.c (pic16_aopOp,pic16_popGet): added handling
2569 of (byte sized) temporaries (assign them to WREG for now)
2570 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
2571 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
2572 this might fix SIGSEGVs on MinGW...
2573 * src/SDCCopt.c (killDeadCode): restored original behaviour
2574 (volatile operands might get thrown away though)
2576 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
2578 * src/pic16/gen.c: fixed bug #1106975,

3040 * src/pic16/genarith.c,
3043 * src/pic16/pcode.c: applied patches #1068154 and #1070213
3045 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
3047 Large cummulative patch for pic16 port.
3048 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
3049 to call when a stack overflow occurs,
3050 * (malloc.h): added CVS Id tag,
3051 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3053 * added libc directory. The current version of LibC contains string
3054 functions, ctype functions and macros and some functions of the
3055 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3056 be extensively tested in the future. Standard disclaimer here.
3057 Library is not automatically build yet. But one can build it by
3058 invoking 'make' inside the libc directory.
3059 * added ADC library under libio. Preliminary version yet.
3061 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
3062 * src/pic16/gen.c (aopForRemat): asmop size is filled by
3063 aopForRemat() now and not by pic16_aopOp(),
3064 * (pic16_popGetTempReg): removed warning messgae when allocating
3065 temporary registers, its a buggy feature and will be removed,
3066 * (pic16_popGet): set register instance field in AOP_CRY,
3067 * (pic16_outBitC): fixed for results in size greater than 1,
3068 * (genUminusFloat): fixed for pic16, ported code from mcs51,
3069 * (pic16_storeForReturn): optimized return of 0,
3070 * (genCmp): experimental code for new genCmp which uses PIC18's
3071 special compare&skip instructions. Initial tests fail some times
3072 with variables grater than 1 byte in size, so new code is disabled,
3073 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3075 * (genCast): began a fix to optimize the casting of a bit to another
3076 bit, now assigning a bitfield to another bitfield will fail, sorry,
3077 * src/pic16/main.c: disabled the use of lr-support feature,
3078 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
3079 * added some function prototypes, added function _debugf prototype,
3080 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
3081 bits with offset (case PO_GPR_BIT),
3082 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
3084 * (isBankInstruction): modified to return 0 for no banking instruction,
3085 and 1 for banking instruction,
3086 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3087 caused stop processing pCodes after a inline assembly block,
3088 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
3089 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
3090 registers when it shouldn't,
3091 * src/pic16/ralloc.c (allocReg): add preliminary support for
3092 supporting a limited set of temporary registers,
3094 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3096 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
3097 genDataPointerSet): ensure assignments always copy in MSB to LSB
3099 (loadRegFromAop): recognize CLRH optimization,
3100 (genFunction): optimize RECEIVE iCodes in reentrant functions
3102 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3104 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
3105 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
3107 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

6102 loaded with the linker search paths (-L arguments) and the libraries
6103 to be linked with the current source (-l arguments). Changes
6104 currently will affect only the pic16 port.
6105 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6106 include path the port specific paths and port specific libraries,

6127 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6128 when generating output files to configure the pic16 library,
6129 but now I've commented it out, since gputils aren't installed in the
6130 SF compile farm, so library won't compile
6132 * device/lib/Makefile.in (version 1.56): initially I've added in
6133 target 'all' the prerequestive 'model-pic16' so it compiled the
6134 pic16 library, but now I've commented it out for the same reasons
6136 * added targets 'model-pic16' and 'objects-pic16' to compile the
6138 * added target 'port-specific-objects-pic16' to handle the
6139 generated libraries and copy them into the build/ directory
6140 * added target 'clean-intermediate-pic16' to clean intermediate
6141 files into pic16 directory
6142 * in target 'installdirs' added line to create directory pic16 in
6143 the installation path
6145 * device/include/Makefile.in (version 1.11): in target 'install'
6146 added lines to copy all header files to installation path,
6147 * in target 'installdirs' added line create directory for pic16
6148 headers in the installation path

6163 * src/z80/main.c (_parseOptions): fixed the portmode= command line
6164 option so that it actually works. Made it specific to the z80, since
6165 the gbz80 doesn't have these kinds of I/O ports.
6167 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6169 * device/include/z180.h,

6178 portmode; added deprecation warning for bank= and protmode= forms.
6179 Also, guard against buffer overflow.
6180 * src/z80/gen.c (aopGet): generate better code for sfr banked read
6182 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6184 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also

6191 Mainly changes to support compilation of the device libraries
6192 * src/pic16/device.c: stack is allocated via symbol and not
6193 via literal number. The symbol is placed in the corresponding
6194 position of the data ram
6195 * (pic16_dump_section): relocatable and absolute uninitialized
6196 data are now emitted in sorted order to reduce section naming,
6197 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6198 weren't marked as being in the access bank,
6200 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6202 Added portion of GNU PIC Library under the directory
6203 device/include/pic16 and device/lib/pic16. These files
6204 contain the declarations of SFRs for the PIC18Fxx2 devices.
6205 The directory is initialized via configure from toplevel.
6207 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
6209 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
6210 the spilllocations to be compared correctly

6234 * doc/sdccman.lyx: Moved and added some sections, small changes
6235 all over. Telling LaTeX to be less strict with word spacing
6236 to better keep the right margin. Changed some notes about
6237 maintainance of the ports in section 3.2.1 - is it OK like this?
6239 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

6276 UPPER for immediate operands,
6277 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
6279 * src/pic16/peeph.def: all peepholes with movff are commented out,
6280 because there is a problem in the pcode peep optimizer,
6281 * src/pic16/ralloc.c: the register allocator can now reuse local
6282 function symbols for another function. This saves register usage.
6283 * src/pic16/ralloc.h: added flag isLocal in structure regs,
6285 Added file src/pic16/NOTES with information about program writing on
6286 the current port version.

6339 needLinkerScript flag
6341 * src/pic16/gen.c (genAddrOf): fixed bug #863624
6342 * src/pic/glue.c: added variable udata_section_name to
6343 override default uninitialized data segment definition for

6391 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6393 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6394 (default behaviour).
6396 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6398 A python script to validate compiler diagnostic messages. It can be
6399 used to verify that sdcc complains about bad c source code and
6400 gives a good location of the error.
6401 * support/valdiag/Makefile,
6402 * support/valdiag/valdiag.py,
6403 * support/valdiag/tests/*

6420 Bug reported from Jesus Calvino-Fraga
6422 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6424 * sdcc.spec: updated
6425 * device/include/Makefile.in: don't install CVS directories
6426 * device/lib/Makefile.in: added removal of CVS directories after install
6427 * doc/Makefile: fixed install, added local_icons
6428 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6429 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6430 * src/ds390/gen.c (genRightShift): fixed bug #870788
6431 * src/SDCCast.c (decorateType): fixed bug #870781
6433 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6435 PIC16 port related changes:
6436 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6437 added variable stackPos,
6439 * gen.c: genCall, assignResultValue: added support for
6440 pushing/retrieving function parameters to/from stack,
6441 genFunction,genEndFunction: setup stack frame for the
6443 genAddrOf: will be changed according to bug 863624
6445 * added files genutils.c and genutils.h which contain gen*
6446 debugged and optimised functions extracted from gen.c
6448 * glue.c: added variable 'externs' which holds extern symbols,
6449 pic16emitRegularMap: is modified to properly handle relocatable
6450 symbols under the new scheme,
6451 pic16createInterruptVect: is modified
6452 pic16printPublics: is modified to emit 'global' assembler directives,
6453 added pic16_printExterns to print extern symbols,
6454 pic16glue: initializes stack/frame pointer in the beginning of
6455 the assembly output. Temporary hack, will be corrected later,
6456 because gplink yet does not support stack and SDCC does not
6457 yet support a type of crt0.o object to create the final binary.
6459 * Removed many lines that contain 8051 legacy code.
6460 * The code is finally placed under a 'code' directive.
6461 * Added port specific options.
6463 * _process_pragma: simplified since now we do not need *special*
6464 include file to define SFR registers. But a separate header
6465 will be needed. This will be developed later.
6466 * _pic16_parseOptions: added, parses port specific options:
6467 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6468 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6469 --preplace-udata-with=
6471 * _pic16_setDefaultOptions: modified to initialize section names,
6472 but hack is temporarly out of order since it needs improvement.
6473 * _pic16_genAssemblerPreamble: configuration words are emitted by
6474 their address instead of their name. This part is incomplete and
6475 supports only the 18Fxx2 devices. Other devices will emit an error
6476 during assembly since they do not contain the same set of config
6478 * _pic16_genIVT: is modified,
6480 * pcode.c: added definitions for some hardware registers that are needed
6482 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6483 All PCI entries are updated. Now LFSR is supported.
6484 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6485 * added pic16_newpCodeOpLit2 to support instructions with
6486 two literal arguments
6487 * pic16_pCode2str: corrected code that emits assembler instructions
6488 with two literal operands and those that have an access bit modifier
6489 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6490 this fixes a bug which caused some labels to be lost, when an
6491 assembler directive was added, i.e. banksel,
6492 * pic16_FixRegisterBanking: improved logic that causes the insertion
6494 * InlineFunction: functions that are called once, are not any more
6495 inlined. This can be a port option in the future,
6497 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6499 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6500 hold the corresponding uninitialized symbols,
6501 * pic16_allocProcessorRegister: registers have explicit marked the
6503 * pic16_allocInternalRegister: registers are explicit marked as
6505 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6506 processing list, so bit registers were lost,
6509 * ralloc.h: added field 'accessBank' and original symbol operand
6510 in register definition,
6511 * removed the field isMapped from register definition,
6513 ** Several functions have been removed from various sources:
6514 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6515 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6516 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6517 pic16_assignRelocatableRegisters
6519 ** others have been introduced:
6520 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6521 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6523 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6525 * support/scripts/inc2h.pl: changed definition of BIT_AT
6526 to emit 'sbit at' instead of 'bit at'. This was a request.
6528 PIC16 port related preliminary changes:
6529 * gen.c: prefixed function popRegFromString with
6530 pic16_ and all references to it corrected
6531 * pcode.c: all pic16_pc_* hardware registers prefixed
6532 with underscore (_),
6533 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6534 * ralloc.c: newReg(): when register is REG_SFR then
6535 set address to rIdx,
6536 pic16_allocProcessorRegister(): marks register wasUsed=0
6537 pic16_writeUsedRegs(): added a call to assign processor
6538 registers via pic16_assignFixedRegisters
6540 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6542 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6543 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6544 variables in unused register banks. Also the SSEG is placed
6545 wherever there is enough space for it, and IDATA can be anywhere
6546 in internal RAM. For now compile using -Wl-Y[stack_size].
6547 The mem file is different for this option as well, since it
6548 makes no sense of talking about DSEG lenght.
6550 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6552 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6553 in certain cases, e.g. when ROM assignment, patch provided
6554 from Albert den Haan.
6556 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7603 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7605 Try to make the peephole optimizer smarter by maintaining
7606 an association between the assembly source code and the
7607 iCodes that originated them. Put this information to use
7608 with a new peephole rule condition "notVolatile" so that
7609 the rules can be aggressive yet still safe.

7622 if the left or right operand symbols have the accuse flag set.
7624 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7626 Changed the type of the result of the ! (NOT) operator to char;
7627 previously it returned the same type as the source. This allows
7628 us to eliminate all the genFloatNot functions (all of its target
7629 implementations were very buggy) since !float can use the same
7632 * src/SDCCicode.c (ast2iCode): ! returns char

7641 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7642 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7643 during interrupts. Ensure WSAVE is located at a shared bank address.
7644 2. Fixed page selection in some places
7645 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7646 the registers name strings.
7647 4. Fixed "signed / unsigned compare" compiler warnings.
7648 5. The PIC port manages its own allocation of the general purpose
7649 registers, but makes no attempt to reuse them. As a result when
7650 compiling it soon runs out of general purpose registers. Some
7651 additional code was added to the files pcode.c and device.c to walk
7652 through the function call tree and rename the registers so that they
7662 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7663 genPlus() & genMinus() when the result is the same as left or right

7669 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7671 Made bitfield a distinct type from bit so that bitfields
7672 convert as per ANSI C and bits retain their traditional
7673 boolean style behaviour. Implemented bitfield support in
7681 * src/ds390/gen.c: bit v bitfield split
7682 * src/z80/gen.c: New support for bitfields
7683 * support/regression/tests/bitfields.c: reenabled z80,
7686 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7688 Rules 246.x, 247.x relate to bitfields, the others speed up
7689 access to xdata mapped I/O devices.
7691 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7693 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7695 Cleaned up genPackBits and genUnpackBits and added two helper
7696 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7697 for literal assignments in genPackBits (thanks to Frieder for
7703 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7705 Fixed bug #748310 (pointer to function type mishandled when the
7706 function name is omitted). Also fixed a SIGSEGV when a function
7707 attribute (reentrant, etc) is used on a non-function or on a
7708 function but misplaced before the parameter list.

7735 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7737 Made the constant following the "interrupt" keyword optional. If
7738 omitted, the function will not automatically be given an entry
7739 in the interrupt vector table (similar to #pragma NOIV, but
7740 less syntacticly kludgy). The interrupt number is also now
7741 range checked. Also fixed a bug in the high order bit example

8217 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
8218 the regression tests I'm not brave enough to enable 245.b, 245.c
8219 * doc/sdccman.lyx: added latex preamble for hyperref package.
8220 Using pdflatex this will give you a hyperlinked pdf file with
8221 bookmarks. (prepend '%' before /usepackage if this breaks something)

8262 it can be defined with CFLAGS when running configure
8263 * src/SDCCmain.c: fixed compiling + linking with object files
8265 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

8268 added --disable-pic16-port
8269 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
8270 * src/SDCCmain.c: linkOptions is changed to set *,
8271 added if/endif conditional macros to remove options help
8272 messages from optionsTable when a port is not configured, added
8273 support for the PIc16 port in the ports table, when executing
8274 the compiler with no port specified on command line, a default
8275 port is selected with the new macro DEFAULT_PORT which is
8276 defined in port.h, in setDefaultOptions() linkOptions is removed
8277 from initialization assignment, since now it is a set,
8278 parseCmdLine uses setParseWithComma for linkOptions, in
8279 linkEdit() linkOptions are accessed with new function indexSet()
8280 which returns the i'th item of a set variable. See SDCCset.c, in
8281 linkEdit() when calling buildCmdLine(), added linkOptions as
8282 last argument. Now users can pass arguments to gplink via the
8283 -Wl option, main() uses pic16glue() to glue up pic16 programs
8284 * src/SDCCpeeph.c: various changes to support pic16

8295 * src/pic16/glue.c: commented out some error producing lines
8296 * src/pic16/main.c: __config directives are commented out to stop
8297 gpasm complaining and test the linkage with gplink, _linkCmd and
8298 _asmCmd changed to be more gplink and gpasm friendly
8299 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8300 produced an error when parsed, peep rule 12 is added to utilize
8301 movff, but it is commented out since the pCode does not support
8302 yet a command with 2 address arguments
8304 2003-05-18 <johan AT balder>
8306 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8331 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
8333 2003-05-11 Borut Razem <borut.razem AT siol.net>
8335 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
8336 the path of bin directory, so that PATH is the only env. variable, which has to be set
8337 in case of standard installation.
8338 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

9324 2003-01-07 <johan AT balder>
9326 * src/SDCCast.c (decorateType): fixed bug #600035

9341 * src/SDCCicode.c: fixed array add
9343 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
9344 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
9345 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9347 2003-01-04 <johan AT balder>
9349 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9351 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9352 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9354 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

9361 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
9362 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
9364 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9365 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9367 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9369 * in \sdcc\as\mcs51\ changed these files in order to create an
9370 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9371 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9372 following files to include the previous two files: aslink.dsp,
9373 Makefile.aslink, Makefile.bcc, and Makefile.in.
9375 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9376 .adb instead of .cdb
9378 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9380 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9381 value from option --iram-size.
9383 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9385 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9388 2002-09-18 <wiml AT hhhh.org>
9390 * SDCClrange.h: exposed setFromRange() and setToRange()
9391 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9392 packRegsForAccUse() (bug 542397)
9393 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9394 multiple times and emitting the fetch operations more than once
9395 added aopGetUsesAcc() function to allow binary operators to
9396 fetch their operands in the correct order; made genMinus() emit
9397 compact code for X = LITERAL - Y
9399 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9400 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9401 sprintf() in line 1267.
9403 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9404 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9407 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9408 Changes to aslink (All the changes are marked with 'JCF'):
9410 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9413 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9414 area BSEG. Also moves, if possible, the DATA area down into the internal
9415 ram so more space is available.
9417 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9420 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9421 not bytes. Function summary() which creates a memory usage summary
9422 file with extension .mem. Reports of overlaping stack and small stack
9423 size. If the space for the stack is less than 16 bytes aslink trows a
9426 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9427 the 8051. Option 'y' for memory summary output file.
9429 Changes to sdcc (All the changes are marked with 'JCF'):
9431 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9433 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9434 overlaying area for it (uses RegBankUsed[4]).
9436 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9437 bank zero as used by default. By default aslink locates the stack
9438 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9439 the creation of the .mem file. Delegates the allocation of data area
9440 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9441 the begining of the stack area to aslink.
9443 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9444 glue() in SDCCglue.c creates an area for it.
9446 2002-09-03 Borut Razem <borut.razem AT siol.net>
9447 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9448 sdcc/src/pic/glue.c:
9449 introduced atexit() handler for teporay files removal in case of
9450 errors, assertions, ...
9452 2002-08-29 Borut Razem <borut.razem AT siol.net>
9453 * sdcc/support/cpp2/auto-host_vc_in.h:
9454 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9455 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9456 Maybe there is a similar problem with BORLANDC? It should be checked!
9458 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9459 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9460 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9461 was not executed, and the compiler (cl) launched a warning:
9462 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9464 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9465 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9467 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9468 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9470 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9471 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,

9473 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9474 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9475 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9476 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9477 - added Release configuration in VS projects
9478 - review of compiler an linker options
9479 - VC .exe files are generated in bin_vc directory, not to interfere
9480 with binaries generated from other projects (cygwin, mingw, bcc ...)
9482 * sdcc/src/yacc.dsp: added
9484 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9485 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9486 and insert the version number definitions from .version
9488 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9490 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9491 added - genarate auto-host.h using auto-host_vc_in.h as template
9494 removed from CVS, generated automatically
9496 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9497 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9499 2002-08-11 Borut Razem <borut.razem AT siol.net>
9500 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9502 2002-08-10 Borut Razem <borut.razem AT siol.net>
9503 * src/SDCCmain.c (main):
9504 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9505 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9506 The consequence was that some temporary files were not removed.
9509 unification of code in functions tempfilename() and tempfile():
9510 function tempnam() is defined in Visual Studio 6.0 and .NET
9512 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9514 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9515 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9516 - removed compiler command line option /WX: Treats all warnings as errors
9517 - update a list of source files, included into the project
9519 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9520 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:

9718 Previous fix was not good. basic blocks that have "break" or "return" are
9719 not really partof a loop , but live ranges used in these blocks should
9720 be live thru the entire loop, so set partOfLoop but don't add them to
