2166 * device/lib/pic16/startup/{crt0i.c, crt0iz.c}: redesign of the
2167 _do_cinit function, because the previous failed when local variables
2168 where not placed in the same memory bank,
2169 * device/lib/pic16/libsdcc/char/: various modifications to improve
2170 library performance,

2180 * src/pic16/gen.c (genSkipc): fixed semantics (execute branch
2181 if condition == CARRY)
2182 * (genCmp): adapted to new genSkipc semantics
2183 * src/pic16/genutils.c (pic6_genCmp_special): removed side effect
2184 on rIfx (genCmp was broken)
2186 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2188 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
2189 * src/z80/main.c (_keywords[]),
2190 * src/SDCCglobal.h (struct options),
2192 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
2193 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
2194 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
2195 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
2196 always available in leading double underscore form. The C99 support is
2197 mostly missing, but it's a start.
2198 * support/regression/tests/bug-227710.c: fixed nonconforming use of
2199 reserved identifier "__data".
2201 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
2203 * src/mcs51/peeph.def: fixed bug 1170013
2205 2005-03-22 Maarten Brock <sourceforge.brock AT dse.nl>

2211 * src/SDCCcflow.c (dfNumCompare): committed the wrong version of this
2214 2005-03-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2216 * src/port.h (struct PORT),

2244 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
2245 immedDom() returning wrong block; probably fixes bug #1160833)
2247 2005-03-20 Borut Razem <borut.razem AT siol.net>
2249 * support/scripts/inc2h.pl: WIN32 port
2251 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
2253 * device/lib/makefile.in: added abs.c and labs.c
2255 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
2257 * device/include/stdint.h: added
2258 * device/lib/abs.c: added
2259 * device/lib/labs.c: added
2260 * device/include/stdlib.h: added abs() and labs() prototypes

2277 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2279 * device/lib/printf_large.c: removed inline assembly for portability and
2280 readability. Use printf_fast if speed or size are more important.
2281 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2282 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2284 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2286 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2287 prevent compiler warning
2289 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2291 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2292 moved to level 0 and declared as static. Also they are explicit
2293 placed in access bank. This was necessery because some times they
2294 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2295 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2296 optimizations. Currently only compare to unsigned char is implemented,
2297 * src/pic16/gen.c: added fReturnIdx array,
2298 * (struct resolvedIfx) is moved to gen.h and made public,
2299 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2300 * (aopForSym): added an optimization to directly store in stack of
2301 the operand of a SEND iCode,
2302 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2303 but as registers instead (AOP_REG) using the fReturnIdx array,
2304 * (pic16_freeAsmop): remove the freed register from the
2305 _G.sregsAlloc field,
2306 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2307 a compare of 'WREG',
2308 * (pic16_popGetTempRegCond): changed function prototype, now
2309 function takes also a bitVector argument v which holds the current
2310 set of registers that are allocated for stack access by aopForSym,
2311 registers allocated in aopForSym for accessing stack symbols are not
2312 any more part of the functions usedRegs field,
2313 * (genCall): some times aopOp is called for a stack variable to be
2314 send, aopForSym might perform the push, if this is true make sure
2315 that genCall doesn't push the variable twice by testing _G.resDirect,
2316 * (genFunction): changed testing for unspecified interrupt number
2317 from 256 to INTNO_UNSPEC,
2318 * modified selection scheme of frame pointer generation. Previously
2319 if function did use local registers a frame pointer was generated,
2320 now a frame pointer is generated only if function has arguments
2321 (that need PLUSW2 register access), or has stack arguments, or the
2322 compiler is not instructed to omit the frame pointer,
2323 * (genEndFunction): before restoring local registers that were saved
2324 in the function preamble, also restore the registers that *might*
2325 have been allocated for stack access,
2326 * (genRet): removed some old comments,
2327 * (genCmp, the active (RN's) version): added a call to the
2328 pic16_genCmp_special function to perform the compare with a more
2329 robust and optimized way,
2330 * (genInline): a feature has been added in inline code generation,
2331 which allows a wildcard variable substitution when writing inline
2332 assembly. Code is incomplete and experimental therefore undocumented,
2333 * (genCast): changed order of aopOp for result and right to allow
2334 aopForSym to directly load the result if possible,
2335 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2336 perform an optimized compare on some selected special occasions,
2337 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2338 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2339 generate an IVT any more,
2340 * src/pic16/main.c (pic16_optionsTable): added command line option
2342 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2343 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2345 * src/pic16/NOTES: Raphael Neider added in list of active developers
2346 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2347 jumptable_end to prevent bug #,
2348 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2349 inCond and outCond fields,
2350 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2351 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2352 turn off register spilling,
2353 * (packRegsForOneUse): synced with other ports' versions although it
2354 is not used currently,
2355 * (pic16_packRegisters): added an optimization while reading
2356 structure bitfields, some registers may be saved (malloc code is
2357 decreased by 80 bytes)
2359 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2361 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2362 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2363 this can be optimized more?
2365 2005-03-10 Raphael Neider <rneider AT web.de>
2367 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2368 genNearPointerGet): (hopefully) fixed access to bitfields via
2369 pointers (p->bitN = x; and x = p->bitN; failed)
2371 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

2557 of (byte sized) temporaries (assign them to WREG for now)
2558 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
2559 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
2560 this might fix SIGSEGVs on MinGW...
2561 * src/SDCCopt.c (killDeadCode): restored original behaviour
2562 (volatile operands might get thrown away though)
2564 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
2566 * src/pic16/gen.c: fixed bug #1106975,

3033 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
3035 Large cummulative patch for pic16 port.
3036 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
3037 to call when a stack overflow occurs,
3038 * (malloc.h): added CVS Id tag,
3039 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3041 * added libc directory. The current version of LibC contains string
3042 functions, ctype functions and macros and some functions of the
3043 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3044 be extensively tested in the future. Standard disclaimer here.
3045 Library is not automatically build yet. But one can build it by
3046 invoking 'make' inside the libc directory.
3047 * added ADC library under libio. Preliminary version yet.
3049 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
3050 * src/pic16/gen.c (aopForRemat): asmop size is filled by
3051 aopForRemat() now and not by pic16_aopOp(),
3052 * (pic16_popGetTempReg): removed warning messgae when allocating
3053 temporary registers, its a buggy feature and will be removed,
3054 * (pic16_popGet): set register instance field in AOP_CRY,
3055 * (pic16_outBitC): fixed for results in size greater than 1,
3056 * (genUminusFloat): fixed for pic16, ported code from mcs51,
3057 * (pic16_storeForReturn): optimized return of 0,
3058 * (genCmp): experimental code for new genCmp which uses PIC18's
3059 special compare&skip instructions. Initial tests fail some times
3060 with variables grater than 1 byte in size, so new code is disabled,
3061 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3063 * (genCast): began a fix to optimize the casting of a bit to another
3064 bit, now assigning a bitfield to another bitfield will fail, sorry,
3065 * src/pic16/main.c: disabled the use of lr-support feature,
3066 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
3067 * added some function prototypes, added function _debugf prototype,
3068 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
3069 bits with offset (case PO_GPR_BIT),
3070 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
3072 * (isBankInstruction): modified to return 0 for no banking instruction,
3073 and 1 for banking instruction,
3074 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3075 caused stop processing pCodes after a inline assembly block,
3076 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
3077 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
3078 registers when it shouldn't,
3079 * src/pic16/ralloc.c (allocReg): add preliminary support for
3080 supporting a limited set of temporary registers,
3082 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3084 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
3085 genDataPointerSet): ensure assignments always copy in MSB to LSB
3087 (loadRegFromAop): recognize CLRH optimization,
3088 (genFunction): optimize RECEIVE iCodes in reentrant functions
3090 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3092 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
3093 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
3095 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08
3096 * src/hc08/main.c (_hc08_setDefaultOptions): default xdata to be
3097 contiguous with data

3106 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks

6087 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6089 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6090 loaded with the linker search paths (-L arguments) and the libraries
6091 to be linked with the current source (-l arguments). Changes
6092 currently will affect only the pic16 port.
6093 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6094 include path the port specific paths and port specific libraries,
6095 * gplink command now contains the $3 argument,
6096 * src/pic16/device.h,
6097 * src/pic16/device.c,: structure PIC_device is made public and

6113 Documenting changes from previous commits.
6114 * configure.in (version 1.56),
6115 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6116 when generating output files to configure the pic16 library,
6117 but now I've commented it out, since gputils aren't installed in the
6118 SF compile farm, so library won't compile
6120 * device/lib/Makefile.in (version 1.56): initially I've added in
6121 target 'all' the prerequestive 'model-pic16' so it compiled the
6122 pic16 library, but now I've commented it out for the same reasons
6124 * added targets 'model-pic16' and 'objects-pic16' to compile the
6126 * added target 'port-specific-objects-pic16' to handle the
6127 generated libraries and copy them into the build/ directory
6128 * added target 'clean-intermediate-pic16' to clean intermediate
6129 files into pic16 directory
6130 * in target 'installdirs' added line to create directory pic16 in

6181 via literal number. The symbol is placed in the corresponding
6182 position of the data ram
6183 * (pic16_dump_section): relocatable and absolute uninitialized
6184 data are now emitted in sorted order to reduce section naming,
6185 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6186 weren't marked as being in the access bank,
6188 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6190 Added portion of GNU PIC Library under the directory
6191 device/include/pic16 and device/lib/pic16. These files
6192 contain the declarations of SFRs for the PIC18Fxx2 devices.
6193 The directory is initialized via configure from toplevel.
6195 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
6197 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
6198 the spilllocations to be compared correctly

6223 all over. Telling LaTeX to be less strict with word spacing
6224 to better keep the right margin. Changed some notes about
6225 maintainance of the ports in section 3.2.1 - is it OK like this?
6227 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

6267 * src/pic16/peeph.def: all peepholes with movff are commented out,
6268 because there is a problem in the pcode peep optimizer,
6269 * src/pic16/ralloc.c: the register allocator can now reuse local

6346 2004-01-07 Borut Razem <borut.razem AT siol.net>
6348 * support/scripts/sdcc.nsi: update PATH
6349 * support/scripts/sdcc.ico: craeted

6362 include information about variables allocated to the overlay
6365 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6367 * as/mcs51/lkmain.c: Help about -Y option

6379 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6381 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6382 (default behaviour).
6384 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6386 A python script to validate compiler diagnostic messages. It can be
6387 used to verify that sdcc complains about bad c source code and
6388 gives a good location of the error.
6389 * support/valdiag/Makefile,
6390 * support/valdiag/valdiag.py,
6391 * support/valdiag/tests/*
6393 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6395 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

6406 * src/common.h: added ifndef/define/endif macros
6407 around the header file.
6408 Bug reported from Jesus Calvino-Fraga
6410 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6412 * sdcc.spec: updated
6413 * device/include/Makefile.in: don't install CVS directories
6414 * device/lib/Makefile.in: added removal of CVS directories after install
6415 * doc/Makefile: fixed install, added local_icons
6416 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6417 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6418 * src/ds390/gen.c (genRightShift): fixed bug #870788
6419 * src/SDCCast.c (decorateType): fixed bug #870781
6421 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6423 PIC16 port related changes:
6424 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6425 added variable stackPos,
6427 * gen.c: genCall, assignResultValue: added support for
6428 pushing/retrieving function parameters to/from stack,
6429 genFunction,genEndFunction: setup stack frame for the
6431 genAddrOf: will be changed according to bug 863624
6433 * added files genutils.c and genutils.h which contain gen*
6434 debugged and optimised functions extracted from gen.c
6436 * glue.c: added variable 'externs' which holds extern symbols,
6437 pic16emitRegularMap: is modified to properly handle relocatable
6438 symbols under the new scheme,
6439 pic16createInterruptVect: is modified
6440 pic16printPublics: is modified to emit 'global' assembler directives,
6441 added pic16_printExterns to print extern symbols,
6442 pic16glue: initializes stack/frame pointer in the beginning of
6443 the assembly output. Temporary hack, will be corrected later,
6444 because gplink yet does not support stack and SDCC does not
6445 yet support a type of crt0.o object to create the final binary.
6447 * Removed many lines that contain 8051 legacy code.
6448 * The code is finally placed under a 'code' directive.
6449 * Added port specific options.
6451 * _process_pragma: simplified since now we do not need *special*
6452 include file to define SFR registers. But a separate header
6453 will be needed. This will be developed later.
6454 * _pic16_parseOptions: added, parses port specific options:
6455 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6456 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6457 --preplace-udata-with=
6459 * _pic16_setDefaultOptions: modified to initialize section names,
6460 but hack is temporarly out of order since it needs improvement.
6461 * _pic16_genAssemblerPreamble: configuration words are emitted by
6462 their address instead of their name. This part is incomplete and
6463 supports only the 18Fxx2 devices. Other devices will emit an error
6464 during assembly since they do not contain the same set of config
6466 * _pic16_genIVT: is modified,
6468 * pcode.c: added definitions for some hardware registers that are needed
6470 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6471 All PCI entries are updated. Now LFSR is supported.
6472 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6473 * added pic16_newpCodeOpLit2 to support instructions with
6474 two literal arguments
6475 * pic16_pCode2str: corrected code that emits assembler instructions
6476 with two literal operands and those that have an access bit modifier
6477 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6478 this fixes a bug which caused some labels to be lost, when an
6479 assembler directive was added, i.e. banksel,
6480 * pic16_FixRegisterBanking: improved logic that causes the insertion
6482 * InlineFunction: functions that are called once, are not any more
6483 inlined. This can be a port option in the future,
6485 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6487 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6488 hold the corresponding uninitialized symbols,
6489 * pic16_allocProcessorRegister: registers have explicit marked the
6491 * pic16_allocInternalRegister: registers are explicit marked as
6493 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6494 processing list, so bit registers were lost,
6497 * ralloc.h: added field 'accessBank' and original symbol operand
6498 in register definition,
6499 * removed the field isMapped from register definition,
6501 ** Several functions have been removed from various sources:
6502 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6503 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6504 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6505 pic16_assignRelocatableRegisters
6507 ** others have been introduced:
6508 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6509 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6511 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6513 * support/scripts/inc2h.pl: changed definition of BIT_AT
6514 to emit 'sbit at' instead of 'bit at'. This was a request.
6516 PIC16 port related preliminary changes:
6517 * gen.c: prefixed function popRegFromString with
6518 pic16_ and all references to it corrected
6519 * pcode.c: all pic16_pc_* hardware registers prefixed
6520 with underscore (_),
6521 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6522 * ralloc.c: newReg(): when register is REG_SFR then
6523 set address to rIdx,
6524 pic16_allocProcessorRegister(): marks register wasUsed=0
6525 pic16_writeUsedRegs(): added a call to assign processor
6526 registers via pic16_assignFixedRegisters
6528 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6530 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6531 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6532 variables in unused register banks. Also the SSEG is placed
6533 wherever there is enough space for it, and IDATA can be anywhere
6534 in internal RAM. For now compile using -Wl-Y[stack_size].
6535 The mem file is different for this option as well, since it
6536 makes no sense of talking about DSEG lenght.
6538 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6540 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6541 in certain cases, e.g. when ROM assignment, patch provided
6542 from Albert den Haan.
6544 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7567 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7568 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol

7587 A few small changes that speed up the peephole optimizer.
7591 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7593 Try to make the peephole optimizer smarter by maintaining
7594 an association between the assembly source code and the
7595 iCodes that originated them. Put this information to use
7596 with a new peephole rule condition "notVolatile" so that
7597 the rules can be aggressive yet still safe.
7602 * src/mcs51/peeph.def
7604 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7608 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),

7610 if the left or right operand symbols have the accuse flag set.
7612 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7614 Changed the type of the result of the ! (NOT) operator to char;
7615 previously it returned the same type as the source. This allows
7616 us to eliminate all the genFloatNot functions (all of its target
7617 implementations were very buggy) since !float can use the same
7620 * src/SDCCicode.c (ast2iCode): ! returns char
7621 * src/mcs51/gen.c (genNot, genNotFloat),
7622 * src/ds390/gen.c (genNot, genNotFloat),
7623 * src/z80/gen.c (genNot, genNotFloat),
7624 * src/pic/gen.c (genNot, genNotFloat),

7629 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7630 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7631 during interrupts. Ensure WSAVE is located at a shared bank address.
7632 2. Fixed page selection in some places
7633 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7634 the registers name strings.
7635 4. Fixed "signed / unsigned compare" compiler warnings.
7636 5. The PIC port manages its own allocation of the general purpose
7637 registers, but makes no attempt to reuse them. As a result when
7638 compiling it soon runs out of general purpose registers. Some
7639 additional code was added to the files pcode.c and device.c to walk
7640 through the function call tree and rename the registers so that they
7650 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

7657 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7659 Made bitfield a distinct type from bit so that bitfields
7660 convert as per ANSI C and bits retain their traditional
7661 boolean style behaviour. Implemented bitfield support in
7669 * src/ds390/gen.c: bit v bitfield split
7670 * src/z80/gen.c: New support for bitfields
7671 * support/regression/tests/bitfields.c: reenabled z80,
7674 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7676 Rules 246.x, 247.x relate to bitfields, the others speed up
7677 access to xdata mapped I/O devices.
7679 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7681 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7683 Cleaned up genPackBits and genUnpackBits and added two helper
7684 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7685 for literal assignments in genPackBits (thanks to Frieder for
7691 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7693 Fixed bug #748310 (pointer to function type mishandled when the
7694 function name is omitted). Also fixed a SIGSEGV when a function
7695 attribute (reentrant, etc) is used on a non-function or on a
7696 function but misplaced before the parameter list.

7723 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7725 Made the constant following the "interrupt" keyword optional. If
7726 omitted, the function will not automatically be given an entry
7727 in the interrupt vector table (similar to #pragma NOIV, but
7728 less syntacticly kludgy). The interrupt number is also now
7729 range checked. Also fixed a bug in the high order bit example

8232 * src/pic16/pcode.c: Cleaned warnings
8233 * src/pic16/pcodeflow.c: Cleaned warnings
8234 * src/pic16/pcoderegs.c: Cleaned warnings

8250 it can be defined with CFLAGS when running configure
8251 * src/SDCCmain.c: fixed compiling + linking with object files
8253 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

8256 added --disable-pic16-port
8257 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
8258 * src/SDCCmain.c: linkOptions is changed to set *,
8259 added if/endif conditional macros to remove options help
8260 messages from optionsTable when a port is not configured, added
8261 support for the PIc16 port in the ports table, when executing
8262 the compiler with no port specified on command line, a default
8263 port is selected with the new macro DEFAULT_PORT which is
8264 defined in port.h, in setDefaultOptions() linkOptions is removed
8265 from initialization assignment, since now it is a set,
8266 parseCmdLine uses setParseWithComma for linkOptions, in
8267 linkEdit() linkOptions are accessed with new function indexSet()
8268 which returns the i'th item of a set variable. See SDCCset.c, in
8269 linkEdit() when calling buildCmdLine(), added linkOptions as
8270 last argument. Now users can pass arguments to gplink via the
8271 -Wl option, main() uses pic16glue() to glue up pic16 programs

8283 * src/pic16/glue.c: commented out some error producing lines
8284 * src/pic16/main.c: __config directives are commented out to stop
8285 gpasm complaining and test the linkage with gplink, _linkCmd and
8286 _asmCmd changed to be more gplink and gpasm friendly
8287 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8288 produced an error when parsed, peep rule 12 is added to utilize
8289 movff, but it is commented out since the pCode does not support
8290 yet a command with 2 address arguments
8292 2003-05-18 <johan AT balder>
8294 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8321 2003-05-11 Borut Razem <borut.razem AT siol.net>
8323 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
8324 the path of bin directory, so that PATH is the only env. variable, which has to be set

9329 * src/SDCCicode.c: fixed array add
9331 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
9332 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
9333 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9335 2003-01-04 <johan AT balder>
9337 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9339 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9340 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9342 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

9352 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9353 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9355 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9357 * in \sdcc\as\mcs51\ changed these files in order to create an
9358 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9359 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9360 following files to include the previous two files: aslink.dsp,
9361 Makefile.aslink, Makefile.bcc, and Makefile.in.
9363 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9364 .adb instead of .cdb
9366 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9368 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9369 value from option --iram-size.
9371 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9373 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9376 2002-09-18 <wiml AT hhhh.org>
9378 * SDCClrange.h: exposed setFromRange() and setToRange()
9379 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9380 packRegsForAccUse() (bug 542397)
9381 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9382 multiple times and emitting the fetch operations more than once
9383 added aopGetUsesAcc() function to allow binary operators to
9384 fetch their operands in the correct order; made genMinus() emit
9385 compact code for X = LITERAL - Y
9387 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9388 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9389 sprintf() in line 1267.
9391 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9392 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9395 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9396 Changes to aslink (All the changes are marked with 'JCF'):
9398 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9401 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9402 area BSEG. Also moves, if possible, the DATA area down into the internal
9403 ram so more space is available.
9405 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9408 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9409 not bytes. Function summary() which creates a memory usage summary
9410 file with extension .mem. Reports of overlaping stack and small stack
9411 size. If the space for the stack is less than 16 bytes aslink trows a
9414 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9415 the 8051. Option 'y' for memory summary output file.
9417 Changes to sdcc (All the changes are marked with 'JCF'):
9419 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9421 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9422 overlaying area for it (uses RegBankUsed[4]).
9424 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9425 bank zero as used by default. By default aslink locates the stack
9426 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9427 the creation of the .mem file. Delegates the allocation of data area
9428 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9429 the begining of the stack area to aslink.
9431 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9432 glue() in SDCCglue.c creates an area for it.
9434 2002-09-03 Borut Razem <borut.razem AT siol.net>
9435 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9436 sdcc/src/pic/glue.c:
9437 introduced atexit() handler for teporay files removal in case of
9438 errors, assertions, ...
9440 2002-08-29 Borut Razem <borut.razem AT siol.net>
9441 * sdcc/support/cpp2/auto-host_vc_in.h:
9442 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9443 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9444 Maybe there is a similar problem with BORLANDC? It should be checked!
9446 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9447 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9448 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9449 was not executed, and the compiler (cl) launched a warning:
9450 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9452 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9453 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9455 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9456 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9458 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9459 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,

9461 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9462 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9463 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9464 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9465 - added Release configuration in VS projects
9466 - review of compiler an linker options
9467 - VC .exe files are generated in bin_vc directory, not to interfere
9468 with binaries generated from other projects (cygwin, mingw, bcc ...)
9470 * sdcc/src/yacc.dsp: added
9472 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9473 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9474 and insert the version number definitions from .version
9476 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9478 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9479 added - genarate auto-host.h using auto-host_vc_in.h as template
9482 removed from CVS, generated automatically
9484 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9485 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9487 2002-08-11 Borut Razem <borut.razem AT siol.net>
9488 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9490 2002-08-10 Borut Razem <borut.razem AT siol.net>
9491 * src/SDCCmain.c (main):
9492 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9493 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9494 The consequence was that some temporary files were not removed.
9497 unification of code in functions tempfilename() and tempfile():
9498 function tempnam() is defined in Visual Studio 6.0 and .NET
9500 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9502 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9503 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9504 - removed compiler command line option /WX: Treats all warnings as errors
9505 - update a list of source files, included into the project
9507 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9508 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9509 changed project type to Generic Project so that can be correcly converted to VS.NET project
9511 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9513 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9515 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings

9706 Previous fix was not good. basic blocks that have "break" or "return" are
9707 not really partof a loop , but live ranges used in these blocks should
9708 be live thru the entire loop, so set partOfLoop but don't add them to
