2191 on rIfx (genCmp was broken)
2193 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2195 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
2196 * src/z80/main.c (_keywords[]),
2197 * src/SDCCglobal.h (struct options),
2199 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
2200 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
2201 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
2202 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
2203 always available in leading double underscore form. The C99 support is
2204 mostly missing, but it's a start.
2205 * support/regression/tests/bug-227710.c: fixed nonconforming use of
2206 reserved identifier "__data".
2208 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

2254 2005-03-20 Borut Razem <borut.razem AT siol.net>
2256 * support/scripts/inc2h.pl: WIN32 port

2284 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2286 * device/lib/printf_large.c: removed inline assembly for portability and
2287 readability. Use printf_fast if speed or size are more important.
2288 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2289 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2291 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2293 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2294 prevent compiler warning
2296 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2298 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2299 moved to level 0 and declared as static. Also they are explicit
2300 placed in access bank. This was necessery because some times they
2301 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2302 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2303 optimizations. Currently only compare to unsigned char is implemented,
2304 * src/pic16/gen.c: added fReturnIdx array,
2305 * (struct resolvedIfx) is moved to gen.h and made public,
2306 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2307 * (aopForSym): added an optimization to directly store in stack of
2308 the operand of a SEND iCode,
2309 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2310 but as registers instead (AOP_REG) using the fReturnIdx array,
2311 * (pic16_freeAsmop): remove the freed register from the
2312 _G.sregsAlloc field,
2313 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2314 a compare of 'WREG',
2315 * (pic16_popGetTempRegCond): changed function prototype, now
2316 function takes also a bitVector argument v which holds the current
2317 set of registers that are allocated for stack access by aopForSym,
2318 registers allocated in aopForSym for accessing stack symbols are not
2319 any more part of the functions usedRegs field,
2320 * (genCall): some times aopOp is called for a stack variable to be
2321 send, aopForSym might perform the push, if this is true make sure
2322 that genCall doesn't push the variable twice by testing _G.resDirect,
2323 * (genFunction): changed testing for unspecified interrupt number
2324 from 256 to INTNO_UNSPEC,
2325 * modified selection scheme of frame pointer generation. Previously
2326 if function did use local registers a frame pointer was generated,
2327 now a frame pointer is generated only if function has arguments
2328 (that need PLUSW2 register access), or has stack arguments, or the
2329 compiler is not instructed to omit the frame pointer,
2330 * (genEndFunction): before restoring local registers that were saved
2331 in the function preamble, also restore the registers that *might*
2332 have been allocated for stack access,
2333 * (genRet): removed some old comments,
2334 * (genCmp, the active (RN's) version): added a call to the
2335 pic16_genCmp_special function to perform the compare with a more
2336 robust and optimized way,
2337 * (genInline): a feature has been added in inline code generation,
2338 which allows a wildcard variable substitution when writing inline
2339 assembly. Code is incomplete and experimental therefore undocumented,
2340 * (genCast): changed order of aopOp for result and right to allow
2341 aopForSym to directly load the result if possible,
2342 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2343 perform an optimized compare on some selected special occasions,
2344 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2345 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2346 generate an IVT any more,
2347 * src/pic16/main.c (pic16_optionsTable): added command line option
2349 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2350 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2352 * src/pic16/NOTES: Raphael Neider added in list of active developers
2353 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2354 jumptable_end to prevent bug #,
2355 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2356 inCond and outCond fields,
2357 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2358 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2359 turn off register spilling,
2360 * (packRegsForOneUse): synced with other ports' versions although it
2361 is not used currently,
2362 * (pic16_packRegisters): added an optimization while reading
2363 structure bitfields, some registers may be saved (malloc code is
2364 decreased by 80 bytes)
2366 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2368 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2369 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2370 this can be optimized more?
2372 2005-03-10 Raphael Neider <rneider AT web.de>
2374 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2375 genNearPointerGet): (hopefully) fixed access to bitfields via
2376 pointers (p->bitN = x; and x = p->bitN; failed)
2378 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
2380 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

2555 * src/pic16/main.c (_process_pragma): fixed another malloc bug
2556 (sizeof(sectNames) changed to sizeof(sectName))

2564 of (byte sized) temporaries (assign them to WREG for now)
2565 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
2566 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
2567 this might fix SIGSEGVs on MinGW...
2568 * src/SDCCopt.c (killDeadCode): restored original behaviour
2569 (volatile operands might get thrown away though)
2571 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
2573 * src/pic16/gen.c: fixed bug #1106975,

3027 2004-11-25 Vangelis Rokas <vrokas AT otenet.gr>
3029 * src/pic16/pcode.c: fixed bug which may produce error in non-GNU
3032 2004-11-25 Vangelis Rokas <vrokas AT otenet.gr>
3034 * src/pic16/device.h,
3035 * src/pic16/genarith.c,
3038 * src/pic16/pcode.c: applied patches #1068154 and #1070213
3040 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
3042 Large cummulative patch for pic16 port.
3043 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
3044 to call when a stack overflow occurs,
3045 * (malloc.h): added CVS Id tag,
3046 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3048 * added libc directory. The current version of LibC contains string
3049 functions, ctype functions and macros and some functions of the
3050 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3051 be extensively tested in the future. Standard disclaimer here.
3052 Library is not automatically build yet. But one can build it by
3053 invoking 'make' inside the libc directory.
3054 * added ADC library under libio. Preliminary version yet.
3056 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
3057 * src/pic16/gen.c (aopForRemat): asmop size is filled by
3058 aopForRemat() now and not by pic16_aopOp(),
3059 * (pic16_popGetTempReg): removed warning messgae when allocating
3060 temporary registers, its a buggy feature and will be removed,
3061 * (pic16_popGet): set register instance field in AOP_CRY,
3062 * (pic16_outBitC): fixed for results in size greater than 1,
3063 * (genUminusFloat): fixed for pic16, ported code from mcs51,
3064 * (pic16_storeForReturn): optimized return of 0,
3065 * (genCmp): experimental code for new genCmp which uses PIC18's
3066 special compare&skip instructions. Initial tests fail some times
3067 with variables grater than 1 byte in size, so new code is disabled,
3068 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3070 * (genCast): began a fix to optimize the casting of a bit to another
3071 bit, now assigning a bitfield to another bitfield will fail, sorry,
3072 * src/pic16/main.c: disabled the use of lr-support feature,
3073 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
3074 * added some function prototypes, added function _debugf prototype,
3075 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
3076 bits with offset (case PO_GPR_BIT),
3077 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
3079 * (isBankInstruction): modified to return 0 for no banking instruction,
3080 and 1 for banking instruction,
3081 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3082 caused stop processing pCodes after a inline assembly block,
3083 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
3084 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
3085 registers when it shouldn't,
3086 * src/pic16/ralloc.c (allocReg): add preliminary support for
3087 supporting a limited set of temporary registers,
3089 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3091 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
3092 genDataPointerSet): ensure assignments always copy in MSB to LSB
3094 (loadRegFromAop): recognize CLRH optimization,
3095 (genFunction): optimize RECEIVE iCodes in reentrant functions
3097 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3099 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
3100 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
3102 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

6094 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6096 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6097 loaded with the linker search paths (-L arguments) and the libraries
6098 to be linked with the current source (-l arguments). Changes
6099 currently will affect only the pic16 port.
6100 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6101 include path the port specific paths and port specific libraries,
6102 * gplink command now contains the $3 argument,
6103 * src/pic16/device.h,
6104 * src/pic16/device.c,: structure PIC_device is made public and
6105 renamed to PIC16_device, the same for variable Pics which is renamed

6120 Documenting changes from previous commits.
6121 * configure.in (version 1.56),
6122 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6123 when generating output files to configure the pic16 library,
6124 but now I've commented it out, since gputils aren't installed in the
6125 SF compile farm, so library won't compile
6127 * device/lib/Makefile.in (version 1.56): initially I've added in
6128 target 'all' the prerequestive 'model-pic16' so it compiled the
6129 pic16 library, but now I've commented it out for the same reasons
6131 * added targets 'model-pic16' and 'objects-pic16' to compile the
6133 * added target 'port-specific-objects-pic16' to handle the
6134 generated libraries and copy them into the build/ directory
6135 * added target 'clean-intermediate-pic16' to clean intermediate
6136 files into pic16 directory
6137 * in target 'installdirs' added line to create directory pic16 in

6141 added lines to copy all header files to installation path,
6142 * in target 'installdirs' added line create directory for pic16
6143 headers in the installation path

6158 * src/z80/main.c (_parseOptions): fixed the portmode= command line
6159 option so that it actually works. Made it specific to the z80, since
6160 the gbz80 doesn't have these kinds of I/O ports.
6162 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6164 * device/include/z180.h,

6188 via literal number. The symbol is placed in the corresponding
6189 position of the data ram
6190 * (pic16_dump_section): relocatable and absolute uninitialized
6191 data are now emitted in sorted order to reduce section naming,
6192 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6193 weren't marked as being in the access bank,
6195 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6197 Added portion of GNU PIC Library under the directory
6198 device/include/pic16 and device/lib/pic16. These files
6199 contain the declarations of SFRs for the PIC18Fxx2 devices.
6200 The directory is initialized via configure from toplevel.
6202 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
6204 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

6230 all over. Telling LaTeX to be less strict with word spacing
6231 to better keep the right margin. Changed some notes about
6232 maintainance of the ports in section 3.2.1 - is it OK like this?
6234 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

6272 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
6274 * src/pic16/peeph.def: all peepholes with movff are commented out,
6275 because there is a problem in the pcode peep optimizer,
6276 * src/pic16/ralloc.c: the register allocator can now reuse local

6278 * src/pic16/ralloc.h: added flag isLocal in structure regs,
6280 Added file src/pic16/NOTES with information about program writing on
6281 the current port version.

6313 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6316 * src/z80/main.c: added missed needLinkerScript flags (more than
6317 one port structure defined in these file)
6318 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

6334 needLinkerScript flag
6336 * src/pic16/gen.c (genAddrOf): fixed bug #863624
6337 * src/pic/glue.c: added variable udata_section_name to
6338 override default uninitialized data segment definition for
6339 devices only with SHAREBANK memory (reported from Erik Epetrich)
6340 * (pic14emitOverlay): modified to emit a commented overlay segment
6341 directive when no overlay data exist
6342 * (picglue): modified to emit uninitialized data segment
6343 according to udata_section_name

6363 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6365 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
6367 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

6369 include information about variables allocated to the overlay
6372 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6374 * as/mcs51/lkmain.c: Help about -Y option

6386 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6388 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6389 (default behaviour).
6391 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6393 A python script to validate compiler diagnostic messages. It can be
6394 used to verify that sdcc complains about bad c source code and
6395 gives a good location of the error.
6396 * support/valdiag/Makefile,
6397 * support/valdiag/valdiag.py,
6398 * support/valdiag/tests/*
6400 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6402 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

6413 * src/common.h: added ifndef/define/endif macros
6414 around the header file.
6415 Bug reported from Jesus Calvino-Fraga
6417 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6419 * sdcc.spec: updated
6420 * device/include/Makefile.in: don't install CVS directories
6421 * device/lib/Makefile.in: added removal of CVS directories after install
6422 * doc/Makefile: fixed install, added local_icons
6423 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6424 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6425 * src/ds390/gen.c (genRightShift): fixed bug #870788
6426 * src/SDCCast.c (decorateType): fixed bug #870781
6428 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6430 PIC16 port related changes:
6431 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6432 added variable stackPos,
6434 * gen.c: genCall, assignResultValue: added support for
6435 pushing/retrieving function parameters to/from stack,
6436 genFunction,genEndFunction: setup stack frame for the
6438 genAddrOf: will be changed according to bug 863624
6440 * added files genutils.c and genutils.h which contain gen*
6441 debugged and optimised functions extracted from gen.c
6443 * glue.c: added variable 'externs' which holds extern symbols,
6444 pic16emitRegularMap: is modified to properly handle relocatable
6445 symbols under the new scheme,
6446 pic16createInterruptVect: is modified
6447 pic16printPublics: is modified to emit 'global' assembler directives,
6448 added pic16_printExterns to print extern symbols,
6449 pic16glue: initializes stack/frame pointer in the beginning of
6450 the assembly output. Temporary hack, will be corrected later,
6451 because gplink yet does not support stack and SDCC does not
6452 yet support a type of crt0.o object to create the final binary.
6454 * Removed many lines that contain 8051 legacy code.
6455 * The code is finally placed under a 'code' directive.
6456 * Added port specific options.
6458 * _process_pragma: simplified since now we do not need *special*
6459 include file to define SFR registers. But a separate header
6460 will be needed. This will be developed later.
6461 * _pic16_parseOptions: added, parses port specific options:
6462 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6463 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6464 --preplace-udata-with=
6466 * _pic16_setDefaultOptions: modified to initialize section names,
6467 but hack is temporarly out of order since it needs improvement.
6468 * _pic16_genAssemblerPreamble: configuration words are emitted by
6469 their address instead of their name. This part is incomplete and
6470 supports only the 18Fxx2 devices. Other devices will emit an error
6471 during assembly since they do not contain the same set of config
6473 * _pic16_genIVT: is modified,
6475 * pcode.c: added definitions for some hardware registers that are needed
6477 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6478 All PCI entries are updated. Now LFSR is supported.
6479 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6480 * added pic16_newpCodeOpLit2 to support instructions with
6481 two literal arguments
6482 * pic16_pCode2str: corrected code that emits assembler instructions
6483 with two literal operands and those that have an access bit modifier
6484 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6485 this fixes a bug which caused some labels to be lost, when an
6486 assembler directive was added, i.e. banksel,
6487 * pic16_FixRegisterBanking: improved logic that causes the insertion
6489 * InlineFunction: functions that are called once, are not any more
6490 inlined. This can be a port option in the future,
6492 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6494 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6495 hold the corresponding uninitialized symbols,
6496 * pic16_allocProcessorRegister: registers have explicit marked the
6498 * pic16_allocInternalRegister: registers are explicit marked as
6500 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6501 processing list, so bit registers were lost,
6504 * ralloc.h: added field 'accessBank' and original symbol operand
6505 in register definition,
6506 * removed the field isMapped from register definition,
6508 ** Several functions have been removed from various sources:
6509 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6510 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6511 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6512 pic16_assignRelocatableRegisters
6514 ** others have been introduced:
6515 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6516 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6518 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6520 * support/scripts/inc2h.pl: changed definition of BIT_AT
6521 to emit 'sbit at' instead of 'bit at'. This was a request.
6523 PIC16 port related preliminary changes:
6524 * gen.c: prefixed function popRegFromString with
6525 pic16_ and all references to it corrected
6526 * pcode.c: all pic16_pc_* hardware registers prefixed
6527 with underscore (_),
6528 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6529 * ralloc.c: newReg(): when register is REG_SFR then
6530 set address to rIdx,
6531 pic16_allocProcessorRegister(): marks register wasUsed=0
6532 pic16_writeUsedRegs(): added a call to assign processor
6533 registers via pic16_assignFixedRegisters
6535 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6537 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6538 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6539 variables in unused register banks. Also the SSEG is placed
6540 wherever there is enough space for it, and IDATA can be anywhere
6541 in internal RAM. For now compile using -Wl-Y[stack_size].
6542 The mem file is different for this option as well, since it
6543 makes no sense of talking about DSEG lenght.
6545 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6547 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6548 in certain cases, e.g. when ROM assignment, patch provided
6549 from Albert den Haan.
6551 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7104 not occur if the control variable is involved with a
7105 relational operator.

7594 A few small changes that speed up the peephole optimizer.
7598 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7600 Try to make the peephole optimizer smarter by maintaining
7601 an association between the assembly source code and the
7602 iCodes that originated them. Put this information to use
7603 with a new peephole rule condition "notVolatile" so that
7604 the rules can be aggressive yet still safe.
7609 * src/mcs51/peeph.def
7611 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7621 Changed the type of the result of the ! (NOT) operator to char;
7622 previously it returned the same type as the source. This allows
7623 us to eliminate all the genFloatNot functions (all of its target
7624 implementations were very buggy) since !float can use the same

7636 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7637 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7638 during interrupts. Ensure WSAVE is located at a shared bank address.
7639 2. Fixed page selection in some places
7640 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7641 the registers name strings.
7642 4. Fixed "signed / unsigned compare" compiler warnings.
7643 5. The PIC port manages its own allocation of the general purpose
7644 registers, but makes no attempt to reuse them. As a result when
7645 compiling it soon runs out of general purpose registers. Some
7646 additional code was added to the files pcode.c and device.c to walk
7647 through the function call tree and rename the registers so that they
7657 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

7664 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7666 Made bitfield a distinct type from bit so that bitfields
7667 convert as per ANSI C and bits retain their traditional
7668 boolean style behaviour. Implemented bitfield support in
7676 * src/ds390/gen.c: bit v bitfield split
7677 * src/z80/gen.c: New support for bitfields
7678 * support/regression/tests/bitfields.c: reenabled z80,
7681 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7683 Rules 246.x, 247.x relate to bitfields, the others speed up
7684 access to xdata mapped I/O devices.
7686 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7688 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7690 Cleaned up genPackBits and genUnpackBits and added two helper
7691 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7692 for literal assignments in genPackBits (thanks to Frieder for
7698 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7700 Fixed bug #748310 (pointer to function type mishandled when the
7701 function name is omitted). Also fixed a SIGSEGV when a function
7702 attribute (reentrant, etc) is used on a non-function or on a
7703 function but misplaced before the parameter list.

7730 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7732 Made the constant following the "interrupt" keyword optional. If
7733 omitted, the function will not automatically be given an entry
7734 in the interrupt vector table (similar to #pragma NOIV, but
7735 less syntacticly kludgy). The interrupt number is also now
7736 range checked. Also fixed a bug in the high order bit example

8212 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
8213 the regression tests I'm not brave enough to enable 245.b, 245.c
8214 * doc/sdccman.lyx: added latex preamble for hyperref package.
8215 Using pdflatex this will give you a hyperlinked pdf file with

8239 * src/pic16/pcode.c: Cleaned warnings
8240 * src/pic16/pcodeflow.c: Cleaned warnings
8241 * src/pic16/pcoderegs.c: Cleaned warnings

8254 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
8256 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
8257 it can be defined with CFLAGS when running configure
8258 * src/SDCCmain.c: fixed compiling + linking with object files
8260 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
8262 * configure.in: configure for pic16 port,
8263 added --disable-pic16-port
8264 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
8265 * src/SDCCmain.c: linkOptions is changed to set *,
8266 added if/endif conditional macros to remove options help
8267 messages from optionsTable when a port is not configured, added
8268 support for the PIc16 port in the ports table, when executing
8269 the compiler with no port specified on command line, a default
8270 port is selected with the new macro DEFAULT_PORT which is
8271 defined in port.h, in setDefaultOptions() linkOptions is removed
8272 from initialization assignment, since now it is a set,
8273 parseCmdLine uses setParseWithComma for linkOptions, in
8274 linkEdit() linkOptions are accessed with new function indexSet()
8275 which returns the i'th item of a set variable. See SDCCset.c, in
8276 linkEdit() when calling buildCmdLine(), added linkOptions as
8277 last argument. Now users can pass arguments to gplink via the
8278 -Wl option, main() uses pic16glue() to glue up pic16 programs
8279 * src/SDCCpeeph.c: various changes to support pic16

8290 * src/pic16/glue.c: commented out some error producing lines
8291 * src/pic16/main.c: __config directives are commented out to stop
8292 gpasm complaining and test the linkage with gplink, _linkCmd and
8293 _asmCmd changed to be more gplink and gpasm friendly
8294 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8295 produced an error when parsed, peep rule 12 is added to utilize
8296 movff, but it is commented out since the pCode does not support
8297 yet a command with 2 address arguments
8299 2003-05-18 <johan AT balder>
8301 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8326 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
8328 2003-05-11 Borut Razem <borut.razem AT siol.net>
8330 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
8331 the path of bin directory, so that PATH is the only env. variable, which has to be set
8332 in case of standard installation.
8333 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

9336 * src/SDCCicode.c: fixed array add
9338 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
9339 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
9340 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9342 2003-01-04 <johan AT balder>
9344 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9346 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

9359 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9360 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9362 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9364 * in \sdcc\as\mcs51\ changed these files in order to create an
9365 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9366 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9367 following files to include the previous two files: aslink.dsp,
9368 Makefile.aslink, Makefile.bcc, and Makefile.in.
9370 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9371 .adb instead of .cdb
9373 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9375 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9376 value from option --iram-size.
9378 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9380 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9383 2002-09-18 <wiml AT hhhh.org>
9385 * SDCClrange.h: exposed setFromRange() and setToRange()
9386 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9387 packRegsForAccUse() (bug 542397)
9388 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9389 multiple times and emitting the fetch operations more than once
9390 added aopGetUsesAcc() function to allow binary operators to
9391 fetch their operands in the correct order; made genMinus() emit
9392 compact code for X = LITERAL - Y
9394 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9395 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9396 sprintf() in line 1267.
9398 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9399 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9402 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9403 Changes to aslink (All the changes are marked with 'JCF'):
9405 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9408 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9409 area BSEG. Also moves, if possible, the DATA area down into the internal
9410 ram so more space is available.
9412 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9415 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9416 not bytes. Function summary() which creates a memory usage summary
9417 file with extension .mem. Reports of overlaping stack and small stack
9418 size. If the space for the stack is less than 16 bytes aslink trows a
9421 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9422 the 8051. Option 'y' for memory summary output file.
9424 Changes to sdcc (All the changes are marked with 'JCF'):
9426 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9428 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9429 overlaying area for it (uses RegBankUsed[4]).
9431 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9432 bank zero as used by default. By default aslink locates the stack
9433 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9434 the creation of the .mem file. Delegates the allocation of data area
9435 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9436 the begining of the stack area to aslink.
9438 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9439 glue() in SDCCglue.c creates an area for it.
9441 2002-09-03 Borut Razem <borut.razem AT siol.net>
9442 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9443 sdcc/src/pic/glue.c:
9444 introduced atexit() handler for teporay files removal in case of
9445 errors, assertions, ...
9447 2002-08-29 Borut Razem <borut.razem AT siol.net>
9448 * sdcc/support/cpp2/auto-host_vc_in.h:
9449 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9450 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9451 Maybe there is a similar problem with BORLANDC? It should be checked!
9453 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9454 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9455 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9456 was not executed, and the compiler (cl) launched a warning:
9457 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9459 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9460 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9462 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9463 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9465 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9466 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,

9469 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9470 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9471 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9472 - added Release configuration in VS projects
9473 - review of compiler an linker options
9474 - VC .exe files are generated in bin_vc directory, not to interfere
9475 with binaries generated from other projects (cygwin, mingw, bcc ...)
9477 * sdcc/src/yacc.dsp: added
9479 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9480 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9481 and insert the version number definitions from .version
9483 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9485 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9486 added - genarate auto-host.h using auto-host_vc_in.h as template
9489 removed from CVS, generated automatically
9491 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9492 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9494 2002-08-11 Borut Razem <borut.razem AT siol.net>
9495 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9497 2002-08-10 Borut Razem <borut.razem AT siol.net>
9498 * src/SDCCmain.c (main):
9499 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9500 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9501 The consequence was that some temporary files were not removed.
9504 unification of code in functions tempfilename() and tempfile():
9505 function tempnam() is defined in Visual Studio 6.0 and .NET
9507 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9509 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9510 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9511 - removed compiler command line option /WX: Treats all warnings as errors
9512 - update a list of source files, included into the project
9514 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9515 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:

9713 Previous fix was not good. basic blocks that have "break" or "return" are
9714 not really partof a loop , but live ranges used in these blocks should
9715 be live thru the entire loop, so set partOfLoop but don't add them to
