2201 on rIfx (genCmp was broken)
2203 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2205 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
2206 * src/z80/main.c (_keywords[]),
2207 * src/SDCCglobal.h (struct options),
2209 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
2210 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
2211 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
2212 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
2213 always available in leading double underscore form. The C99 support is
2214 mostly missing, but it's a start.
2215 * support/regression/tests/bug-227710.c: fixed nonconforming use of
2216 reserved identifier "__data".
2218 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
2220 * src/mcs51/peeph.def: fixed bug 1170013

2262 immedDom() returning wrong block; probably fixes bug #1160833)
2264 2005-03-20 Borut Razem <borut.razem AT siol.net>
2266 * support/scripts/inc2h.pl: WIN32 port
2268 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
2270 * device/lib/makefile.in: added abs.c and labs.c
2272 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
2274 * device/include/stdint.h: added
2275 * device/lib/abs.c: added

2294 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2296 * device/lib/printf_large.c: removed inline assembly for portability and
2297 readability. Use printf_fast if speed or size are more important.
2298 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2299 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2301 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2303 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2304 prevent compiler warning
2306 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2308 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2309 moved to level 0 and declared as static. Also they are explicit
2310 placed in access bank. This was necessery because some times they
2311 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2312 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2313 optimizations. Currently only compare to unsigned char is implemented,
2314 * src/pic16/gen.c: added fReturnIdx array,
2315 * (struct resolvedIfx) is moved to gen.h and made public,
2316 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2317 * (aopForSym): added an optimization to directly store in stack of
2318 the operand of a SEND iCode,
2319 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2320 but as registers instead (AOP_REG) using the fReturnIdx array,
2321 * (pic16_freeAsmop): remove the freed register from the
2322 _G.sregsAlloc field,
2323 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2324 a compare of 'WREG',
2325 * (pic16_popGetTempRegCond): changed function prototype, now
2326 function takes also a bitVector argument v which holds the current
2327 set of registers that are allocated for stack access by aopForSym,
2328 registers allocated in aopForSym for accessing stack symbols are not
2329 any more part of the functions usedRegs field,
2330 * (genCall): some times aopOp is called for a stack variable to be
2331 send, aopForSym might perform the push, if this is true make sure
2332 that genCall doesn't push the variable twice by testing _G.resDirect,
2333 * (genFunction): changed testing for unspecified interrupt number
2334 from 256 to INTNO_UNSPEC,
2335 * modified selection scheme of frame pointer generation. Previously
2336 if function did use local registers a frame pointer was generated,
2337 now a frame pointer is generated only if function has arguments
2338 (that need PLUSW2 register access), or has stack arguments, or the
2339 compiler is not instructed to omit the frame pointer,
2340 * (genEndFunction): before restoring local registers that were saved
2341 in the function preamble, also restore the registers that *might*
2342 have been allocated for stack access,
2343 * (genRet): removed some old comments,
2344 * (genCmp, the active (RN's) version): added a call to the
2345 pic16_genCmp_special function to perform the compare with a more
2346 robust and optimized way,
2347 * (genInline): a feature has been added in inline code generation,
2348 which allows a wildcard variable substitution when writing inline
2349 assembly. Code is incomplete and experimental therefore undocumented,
2350 * (genCast): changed order of aopOp for result and right to allow
2351 aopForSym to directly load the result if possible,
2352 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2353 perform an optimized compare on some selected special occasions,
2354 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2355 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2356 generate an IVT any more,
2357 * src/pic16/main.c (pic16_optionsTable): added command line option
2359 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2360 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2362 * src/pic16/NOTES: Raphael Neider added in list of active developers
2363 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2364 jumptable_end to prevent bug #,
2365 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2366 inCond and outCond fields,
2367 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2368 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2369 turn off register spilling,
2370 * (packRegsForOneUse): synced with other ports' versions although it
2371 is not used currently,
2372 * (pic16_packRegisters): added an optimization while reading
2373 structure bitfields, some registers may be saved (malloc code is
2374 decreased by 80 bytes)
2376 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2378 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2379 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2380 this can be optimized more?
2382 2005-03-10 Raphael Neider <rneider AT web.de>
2384 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2385 genNearPointerGet): (hopefully) fixed access to bitfields via
2386 pointers (p->bitN = x; and x = p->bitN; failed)
2388 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
2390 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

2565 * src/pic16/main.c (_process_pragma): fixed another malloc bug
2566 (sizeof(sectNames) changed to sizeof(sectName))
2567 Both patches fix segfaults under MinGW.

2573 * src/pic16/gen.c (pic16_aopOp,pic16_popGet): added handling
2574 of (byte sized) temporaries (assign them to WREG for now)
2575 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
2576 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
2577 this might fix SIGSEGVs on MinGW...
2578 * src/SDCCopt.c (killDeadCode): restored original behaviour
2579 (volatile operands might get thrown away though)
2581 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
2583 * src/pic16/gen.c: fixed bug #1106975,

3020 Adding support for replacing ljmps with sjmps in jumptables
3021 generated for switch statements. For now you need to set the
3022 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3023 Now 4 algorithms for mcs51 jumptable generation are used:
3024 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

3052 Large cummulative patch for pic16 port.
3053 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
3054 to call when a stack overflow occurs,
3055 * (malloc.h): added CVS Id tag,
3056 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3058 * added libc directory. The current version of LibC contains string
3059 functions, ctype functions and macros and some functions of the
3060 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3061 be extensively tested in the future. Standard disclaimer here.
3062 Library is not automatically build yet. But one can build it by
3063 invoking 'make' inside the libc directory.
3064 * added ADC library under libio. Preliminary version yet.
3066 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
3067 * src/pic16/gen.c (aopForRemat): asmop size is filled by
3068 aopForRemat() now and not by pic16_aopOp(),

3070 temporary registers, its a buggy feature and will be removed,
3071 * (pic16_popGet): set register instance field in AOP_CRY,

3073 * (genUminusFloat): fixed for pic16, ported code from mcs51,
3074 * (pic16_storeForReturn): optimized return of 0,
3075 * (genCmp): experimental code for new genCmp which uses PIC18's
3076 special compare&skip instructions. Initial tests fail some times
3077 with variables grater than 1 byte in size, so new code is disabled,
3078 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3080 * (genCast): began a fix to optimize the casting of a bit to another
3081 bit, now assigning a bitfield to another bitfield will fail, sorry,
3082 * src/pic16/main.c: disabled the use of lr-support feature,
3083 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
3084 * added some function prototypes, added function _debugf prototype,
3085 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
3086 bits with offset (case PO_GPR_BIT),
3087 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
3089 * (isBankInstruction): modified to return 0 for no banking instruction,
3090 and 1 for banking instruction,
3091 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3092 caused stop processing pCodes after a inline assembly block,
3093 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
3094 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
3095 registers when it shouldn't,
3096 * src/pic16/ralloc.c (allocReg): add preliminary support for
3097 supporting a limited set of temporary registers,
3099 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3101 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
3102 genDataPointerSet): ensure assignments always copy in MSB to LSB
3104 (loadRegFromAop): recognize CLRH optimization,
3105 (genFunction): optimize RECEIVE iCodes in reentrant functions
3107 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3109 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

6107 loaded with the linker search paths (-L arguments) and the libraries
6108 to be linked with the current source (-l arguments). Changes
6109 currently will affect only the pic16 port.
6110 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6111 include path the port specific paths and port specific libraries,
6112 * gplink command now contains the $3 argument,

6130 Documenting changes from previous commits.
6131 * configure.in (version 1.56),
6132 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6133 when generating output files to configure the pic16 library,
6134 but now I've commented it out, since gputils aren't installed in the
6135 SF compile farm, so library won't compile
6137 * device/lib/Makefile.in (version 1.56): initially I've added in
6138 target 'all' the prerequestive 'model-pic16' so it compiled the
6139 pic16 library, but now I've commented it out for the same reasons
6141 * added targets 'model-pic16' and 'objects-pic16' to compile the
6143 * added target 'port-specific-objects-pic16' to handle the
6144 generated libraries and copy them into the build/ directory
6145 * added target 'clean-intermediate-pic16' to clean intermediate
6146 files into pic16 directory
6147 * in target 'installdirs' added line to create directory pic16 in
6148 the installation path
6150 * device/include/Makefile.in (version 1.11): in target 'install'
6151 added lines to copy all header files to installation path,
6152 * in target 'installdirs' added line create directory for pic16
6153 headers in the installation path
6155 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

6168 * src/z80/main.c (_parseOptions): fixed the portmode= command line
6169 option so that it actually works. Made it specific to the z80, since
6170 the gbz80 doesn't have these kinds of I/O ports.
6172 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6174 * device/include/z180.h,

6187 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6189 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
6190 changed interrupt vector table generation to only emit declared vectors.

6196 Mainly changes to support compilation of the device libraries
6197 * src/pic16/device.c: stack is allocated via symbol and not
6198 via literal number. The symbol is placed in the corresponding
6199 position of the data ram
6200 * (pic16_dump_section): relocatable and absolute uninitialized
6201 data are now emitted in sorted order to reduce section naming,
6202 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6203 weren't marked as being in the access bank,
6205 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6207 Added portion of GNU PIC Library under the directory
6208 device/include/pic16 and device/lib/pic16. These files
6209 contain the declarations of SFRs for the PIC18Fxx2 devices.
6210 The directory is initialized via configure from toplevel.
6212 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
6214 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
6215 the spilllocations to be compared correctly

6237 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6239 * doc/sdccman.lyx: Moved and added some sections, small changes
6240 all over. Telling LaTeX to be less strict with word spacing
6241 to better keep the right margin. Changed some notes about
6242 maintainance of the ports in section 3.2.1 - is it OK like this?
6244 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

6281 UPPER for immediate operands,
6282 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
6284 * src/pic16/peeph.def: all peepholes with movff are commented out,
6285 because there is a problem in the pcode peep optimizer,
6286 * src/pic16/ralloc.c: the register allocator can now reuse local

6288 * src/pic16/ralloc.h: added flag isLocal in structure regs,
6290 Added file src/pic16/NOTES with information about program writing on
6291 the current port version.

6344 needLinkerScript flag
6346 * src/pic16/gen.c (genAddrOf): fixed bug #863624
6347 * src/pic/glue.c: added variable udata_section_name to
6348 override default uninitialized data segment definition for
6349 devices only with SHAREBANK memory (reported from Erik Epetrich)
6350 * (pic14emitOverlay): modified to emit a commented overlay segment
6351 directive when no overlay data exist
6352 * (picglue): modified to emit uninitialized data segment
6353 according to udata_section_name

6379 include information about variables allocated to the overlay
6382 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6384 * as/mcs51/lkmain.c: Help about -Y option

6396 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6398 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6399 (default behaviour).
6401 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6403 A python script to validate compiler diagnostic messages. It can be
6404 used to verify that sdcc complains about bad c source code and
6405 gives a good location of the error.
6406 * support/valdiag/Makefile,
6407 * support/valdiag/valdiag.py,
6408 * support/valdiag/tests/*

6425 Bug reported from Jesus Calvino-Fraga
6427 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6429 * sdcc.spec: updated
6430 * device/include/Makefile.in: don't install CVS directories
6431 * device/lib/Makefile.in: added removal of CVS directories after install
6432 * doc/Makefile: fixed install, added local_icons
6433 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6434 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6435 * src/ds390/gen.c (genRightShift): fixed bug #870788
6436 * src/SDCCast.c (decorateType): fixed bug #870781
6438 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6440 PIC16 port related changes:
6441 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6442 added variable stackPos,
6444 * gen.c: genCall, assignResultValue: added support for
6445 pushing/retrieving function parameters to/from stack,
6446 genFunction,genEndFunction: setup stack frame for the
6448 genAddrOf: will be changed according to bug 863624
6450 * added files genutils.c and genutils.h which contain gen*
6451 debugged and optimised functions extracted from gen.c
6453 * glue.c: added variable 'externs' which holds extern symbols,
6454 pic16emitRegularMap: is modified to properly handle relocatable
6455 symbols under the new scheme,
6456 pic16createInterruptVect: is modified
6457 pic16printPublics: is modified to emit 'global' assembler directives,
6458 added pic16_printExterns to print extern symbols,
6459 pic16glue: initializes stack/frame pointer in the beginning of
6460 the assembly output. Temporary hack, will be corrected later,
6461 because gplink yet does not support stack and SDCC does not
6462 yet support a type of crt0.o object to create the final binary.
6464 * Removed many lines that contain 8051 legacy code.
6465 * The code is finally placed under a 'code' directive.
6466 * Added port specific options.
6468 * _process_pragma: simplified since now we do not need *special*
6469 include file to define SFR registers. But a separate header
6470 will be needed. This will be developed later.
6471 * _pic16_parseOptions: added, parses port specific options:
6472 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6473 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6474 --preplace-udata-with=
6476 * _pic16_setDefaultOptions: modified to initialize section names,
6477 but hack is temporarly out of order since it needs improvement.
6478 * _pic16_genAssemblerPreamble: configuration words are emitted by
6479 their address instead of their name. This part is incomplete and
6480 supports only the 18Fxx2 devices. Other devices will emit an error
6481 during assembly since they do not contain the same set of config
6483 * _pic16_genIVT: is modified,
6485 * pcode.c: added definitions for some hardware registers that are needed
6487 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6488 All PCI entries are updated. Now LFSR is supported.
6489 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6490 * added pic16_newpCodeOpLit2 to support instructions with
6491 two literal arguments
6492 * pic16_pCode2str: corrected code that emits assembler instructions
6493 with two literal operands and those that have an access bit modifier
6494 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6495 this fixes a bug which caused some labels to be lost, when an
6496 assembler directive was added, i.e. banksel,
6497 * pic16_FixRegisterBanking: improved logic that causes the insertion
6499 * InlineFunction: functions that are called once, are not any more
6500 inlined. This can be a port option in the future,
6502 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6504 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6505 hold the corresponding uninitialized symbols,
6506 * pic16_allocProcessorRegister: registers have explicit marked the
6508 * pic16_allocInternalRegister: registers are explicit marked as
6510 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6511 processing list, so bit registers were lost,
6514 * ralloc.h: added field 'accessBank' and original symbol operand
6515 in register definition,
6516 * removed the field isMapped from register definition,
6518 ** Several functions have been removed from various sources:
6519 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6520 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6521 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6522 pic16_assignRelocatableRegisters
6524 ** others have been introduced:
6525 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6526 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6528 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6530 * support/scripts/inc2h.pl: changed definition of BIT_AT
6531 to emit 'sbit at' instead of 'bit at'. This was a request.
6533 PIC16 port related preliminary changes:
6534 * gen.c: prefixed function popRegFromString with
6535 pic16_ and all references to it corrected
6536 * pcode.c: all pic16_pc_* hardware registers prefixed
6537 with underscore (_),
6538 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6539 * ralloc.c: newReg(): when register is REG_SFR then
6540 set address to rIdx,
6541 pic16_allocProcessorRegister(): marks register wasUsed=0
6542 pic16_writeUsedRegs(): added a call to assign processor
6543 registers via pic16_assignFixedRegisters
6545 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6547 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6548 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6549 variables in unused register banks. Also the SSEG is placed
6550 wherever there is enough space for it, and IDATA can be anywhere
6551 in internal RAM. For now compile using -Wl-Y[stack_size].
6552 The mem file is different for this option as well, since it
6553 makes no sense of talking about DSEG lenght.
6555 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6557 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6558 in certain cases, e.g. when ROM assignment, patch provided
6559 from Albert den Haan.
6561 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7604 A few small changes that speed up the peephole optimizer.
7608 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7610 Try to make the peephole optimizer smarter by maintaining
7611 an association between the assembly source code and the
7612 iCodes that originated them. Put this information to use
7613 with a new peephole rule condition "notVolatile" so that
7614 the rules can be aggressive yet still safe.
7619 * src/mcs51/peeph.def
7621 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7625 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7626 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7627 if the left or right operand symbols have the accuse flag set.
7629 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7631 Changed the type of the result of the ! (NOT) operator to char;
7632 previously it returned the same type as the source. This allows
7633 us to eliminate all the genFloatNot functions (all of its target
7634 implementations were very buggy) since !float can use the same
7637 * src/SDCCicode.c (ast2iCode): ! returns char

7646 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7647 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7648 during interrupts. Ensure WSAVE is located at a shared bank address.
7649 2. Fixed page selection in some places
7650 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7651 the registers name strings.
7652 4. Fixed "signed / unsigned compare" compiler warnings.
7653 5. The PIC port manages its own allocation of the general purpose
7654 registers, but makes no attempt to reuse them. As a result when
7655 compiling it soon runs out of general purpose registers. Some
7656 additional code was added to the files pcode.c and device.c to walk
7657 through the function call tree and rename the registers so that they
7667 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

7674 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7676 Made bitfield a distinct type from bit so that bitfields
7677 convert as per ANSI C and bits retain their traditional
7678 boolean style behaviour. Implemented bitfield support in
7686 * src/ds390/gen.c: bit v bitfield split
7687 * src/z80/gen.c: New support for bitfields
7688 * support/regression/tests/bitfields.c: reenabled z80,
7691 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7693 Rules 246.x, 247.x relate to bitfields, the others speed up
7694 access to xdata mapped I/O devices.
7696 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7698 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7700 Cleaned up genPackBits and genUnpackBits and added two helper
7701 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7702 for literal assignments in genPackBits (thanks to Frieder for
7708 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7710 Fixed bug #748310 (pointer to function type mishandled when the
7711 function name is omitted). Also fixed a SIGSEGV when a function
7712 attribute (reentrant, etc) is used on a non-function or on a
7713 function but misplaced before the parameter list.

7740 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7742 Made the constant following the "interrupt" keyword optional. If
7743 omitted, the function will not automatically be given an entry
7744 in the interrupt vector table (similar to #pragma NOIV, but
7745 less syntacticly kludgy). The interrupt number is also now
7746 range checked. Also fixed a bug in the high order bit example

8215 * src/avr/avr.dsp, src/ds390/ds390.dsp, src/mcs51/mcs51.dsp,
8216 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
8217 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used

8222 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
8223 the regression tests I'm not brave enough to enable 245.b, 245.c
8224 * doc/sdccman.lyx: added latex preamble for hyperref package.
8225 Using pdflatex this will give you a hyperlinked pdf file with
8226 bookmarks. (prepend '%' before /usepackage if this breaks something)

8267 it can be defined with CFLAGS when running configure
8268 * src/SDCCmain.c: fixed compiling + linking with object files
8270 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

8273 added --disable-pic16-port
8274 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
8275 * src/SDCCmain.c: linkOptions is changed to set *,
8276 added if/endif conditional macros to remove options help
8277 messages from optionsTable when a port is not configured, added
8278 support for the PIc16 port in the ports table, when executing
8279 the compiler with no port specified on command line, a default
8280 port is selected with the new macro DEFAULT_PORT which is
8281 defined in port.h, in setDefaultOptions() linkOptions is removed
8282 from initialization assignment, since now it is a set,
8283 parseCmdLine uses setParseWithComma for linkOptions, in
8284 linkEdit() linkOptions are accessed with new function indexSet()
8285 which returns the i'th item of a set variable. See SDCCset.c, in
8286 linkEdit() when calling buildCmdLine(), added linkOptions as
8287 last argument. Now users can pass arguments to gplink via the
8288 -Wl option, main() uses pic16glue() to glue up pic16 programs
8289 * src/SDCCpeeph.c: various changes to support pic16

8300 * src/pic16/glue.c: commented out some error producing lines
8301 * src/pic16/main.c: __config directives are commented out to stop
8302 gpasm complaining and test the linkage with gplink, _linkCmd and
8303 _asmCmd changed to be more gplink and gpasm friendly
8304 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8305 produced an error when parsed, peep rule 12 is added to utilize
8306 movff, but it is commented out since the pCode does not support
8307 yet a command with 2 address arguments
8309 2003-05-18 <johan AT balder>
8311 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8336 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
8338 2003-05-11 Borut Razem <borut.razem AT siol.net>
8340 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
8341 the path of bin directory, so that PATH is the only env. variable, which has to be set
8342 in case of standard installation.
8343 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

9346 * src/SDCCicode.c: fixed array add
9348 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
9349 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
9350 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9352 2003-01-04 <johan AT balder>
9354 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9356 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9357 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o

9369 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9370 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9372 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9374 * in \sdcc\as\mcs51\ changed these files in order to create an
9375 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9376 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9377 following files to include the previous two files: aslink.dsp,
9378 Makefile.aslink, Makefile.bcc, and Makefile.in.
9380 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9381 .adb instead of .cdb
9383 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9385 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9386 value from option --iram-size.
9388 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9390 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9393 2002-09-18 <wiml AT hhhh.org>
9395 * SDCClrange.h: exposed setFromRange() and setToRange()
9396 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9397 packRegsForAccUse() (bug 542397)
9398 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9399 multiple times and emitting the fetch operations more than once
9400 added aopGetUsesAcc() function to allow binary operators to
9401 fetch their operands in the correct order; made genMinus() emit
9402 compact code for X = LITERAL - Y
9404 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9405 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9406 sprintf() in line 1267.
9408 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9409 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9412 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9413 Changes to aslink (All the changes are marked with 'JCF'):
9415 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9418 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9419 area BSEG. Also moves, if possible, the DATA area down into the internal
9420 ram so more space is available.
9422 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9425 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9426 not bytes. Function summary() which creates a memory usage summary
9427 file with extension .mem. Reports of overlaping stack and small stack
9428 size. If the space for the stack is less than 16 bytes aslink trows a
9431 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9432 the 8051. Option 'y' for memory summary output file.
9434 Changes to sdcc (All the changes are marked with 'JCF'):
9436 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9438 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9439 overlaying area for it (uses RegBankUsed[4]).
9441 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9442 bank zero as used by default. By default aslink locates the stack
9443 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9444 the creation of the .mem file. Delegates the allocation of data area
9445 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9446 the begining of the stack area to aslink.
9448 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9449 glue() in SDCCglue.c creates an area for it.
9451 2002-09-03 Borut Razem <borut.razem AT siol.net>
9452 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9453 sdcc/src/pic/glue.c:
9454 introduced atexit() handler for teporay files removal in case of
9455 errors, assertions, ...
9457 2002-08-29 Borut Razem <borut.razem AT siol.net>
9458 * sdcc/support/cpp2/auto-host_vc_in.h:
9459 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9460 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9461 Maybe there is a similar problem with BORLANDC? It should be checked!
9463 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9464 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9465 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9466 was not executed, and the compiler (cl) launched a warning:
9467 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9469 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9470 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9472 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9473 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9475 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9476 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,

9478 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9479 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9480 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9481 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9482 - added Release configuration in VS projects
9483 - review of compiler an linker options
9484 - VC .exe files are generated in bin_vc directory, not to interfere
9485 with binaries generated from other projects (cygwin, mingw, bcc ...)
9487 * sdcc/src/yacc.dsp: added
9489 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9490 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9491 and insert the version number definitions from .version
9493 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9495 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9496 added - genarate auto-host.h using auto-host_vc_in.h as template
9499 removed from CVS, generated automatically
9501 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9502 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9504 2002-08-11 Borut Razem <borut.razem AT siol.net>
9505 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9507 2002-08-10 Borut Razem <borut.razem AT siol.net>
9508 * src/SDCCmain.c (main):
9509 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9510 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9511 The consequence was that some temporary files were not removed.
9514 unification of code in functions tempfilename() and tempfile():
9515 function tempnam() is defined in Visual Studio 6.0 and .NET
9517 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9519 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9520 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9521 - removed compiler command line option /WX: Treats all warnings as errors
9522 - update a list of source files, included into the project
9524 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,

9538 added newline in the def file to keep MSC compiler satisfied
9540 * sdcc/src/z80/gen.c:
9541 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9542 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC

9722 * sdcc/src/SDCCloop.c:
9723 Previous fix was not good. basic blocks that have "break" or "return" are
9724 not really partof a loop , but live ranges used in these blocks should
9725 be live thru the entire loop, so set partOfLoop but don't add them to
