2153 of the PIC18Fxx[28] devices,
2154 * device/lib/pic16/libc/delay/: NEW, c sources for the delay functions,
2155 * device/lib/pic16/libc/utils/: minor modifications in the .S sources,
2156 * device/lib/pic16/startup/{crt0i.c, crt0iz.c}: redesign of the
2157 _do_cinit function, because the previous failed when local variables
2158 where not placed in the same memory bank,
2159 * device/lib/pic16/libsdcc/char/: various modifications to improve
2160 library performance,
2161 * doc/sdccman.lyx: some reorganization of the PIC16 part, added many

2171 if condition == CARRY)
2172 * (genCmp): adapted to new genSkipc semantics
2173 * src/pic16/genutils.c (pic6_genCmp_special): removed side effect
2174 on rIfx (genCmp was broken)
2176 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2178 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
2179 * src/z80/main.c (_keywords[]),
2180 * src/SDCCglobal.h (struct options),
2182 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
2183 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
2184 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
2185 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
2186 always available in leading double underscore form. The C99 support is
2187 mostly missing, but it's a start.
2188 * support/regression/tests/bug-227710.c: fixed nonconforming use of
2189 reserved identifier "__data".
2191 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
2193 * src/mcs51/peeph.def: fixed bug 1170013

2201 * src/SDCCcflow.c (dfNumCompare): committed the wrong version of this
2204 2005-03-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2206 * src/port.h (struct PORT),

2235 immedDom() returning wrong block; probably fixes bug #1160833)
2237 2005-03-20 Borut Razem <borut.razem AT siol.net>
2239 * support/scripts/inc2h.pl: WIN32 port
2241 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
2243 * device/lib/makefile.in: added abs.c and labs.c
2245 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
2247 * device/include/stdint.h: added
2248 * device/lib/abs.c: added
2249 * device/lib/labs.c: added
2250 * device/include/stdlib.h: added abs() and labs() prototypes
2251 * device/lib/libsdcc.lib: added abs and labs
2252 * device/include/float.h,

2265 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
2267 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2269 * device/lib/printf_large.c: removed inline assembly for portability and
2270 readability. Use printf_fast if speed or size are more important.
2271 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2272 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2274 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2276 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2277 prevent compiler warning
2279 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2281 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2282 moved to level 0 and declared as static. Also they are explicit
2283 placed in access bank. This was necessery because some times they
2284 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2285 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2286 optimizations. Currently only compare to unsigned char is implemented,
2287 * src/pic16/gen.c: added fReturnIdx array,
2288 * (struct resolvedIfx) is moved to gen.h and made public,
2289 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2290 * (aopForSym): added an optimization to directly store in stack of
2291 the operand of a SEND iCode,
2292 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2293 but as registers instead (AOP_REG) using the fReturnIdx array,
2294 * (pic16_freeAsmop): remove the freed register from the
2295 _G.sregsAlloc field,
2296 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2297 a compare of 'WREG',
2298 * (pic16_popGetTempRegCond): changed function prototype, now
2299 function takes also a bitVector argument v which holds the current
2300 set of registers that are allocated for stack access by aopForSym,
2301 registers allocated in aopForSym for accessing stack symbols are not
2302 any more part of the functions usedRegs field,
2303 * (genCall): some times aopOp is called for a stack variable to be
2304 send, aopForSym might perform the push, if this is true make sure
2305 that genCall doesn't push the variable twice by testing _G.resDirect,
2306 * (genFunction): changed testing for unspecified interrupt number
2307 from 256 to INTNO_UNSPEC,
2308 * modified selection scheme of frame pointer generation. Previously
2309 if function did use local registers a frame pointer was generated,
2310 now a frame pointer is generated only if function has arguments
2311 (that need PLUSW2 register access), or has stack arguments, or the
2312 compiler is not instructed to omit the frame pointer,
2313 * (genEndFunction): before restoring local registers that were saved
2314 in the function preamble, also restore the registers that *might*
2315 have been allocated for stack access,
2316 * (genRet): removed some old comments,
2317 * (genCmp, the active (RN's) version): added a call to the
2318 pic16_genCmp_special function to perform the compare with a more
2319 robust and optimized way,
2320 * (genInline): a feature has been added in inline code generation,
2321 which allows a wildcard variable substitution when writing inline
2322 assembly. Code is incomplete and experimental therefore undocumented,
2323 * (genCast): changed order of aopOp for result and right to allow
2324 aopForSym to directly load the result if possible,
2325 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2326 perform an optimized compare on some selected special occasions,
2327 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2328 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2329 generate an IVT any more,
2330 * src/pic16/main.c (pic16_optionsTable): added command line option
2332 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2333 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2335 * src/pic16/NOTES: Raphael Neider added in list of active developers
2336 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2337 jumptable_end to prevent bug #,
2338 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2339 inCond and outCond fields,
2340 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2341 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2342 turn off register spilling,
2343 * (packRegsForOneUse): synced with other ports' versions although it
2344 is not used currently,
2345 * (pic16_packRegisters): added an optimization while reading
2346 structure bitfields, some registers may be saved (malloc code is
2347 decreased by 80 bytes)
2349 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2351 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2352 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2353 this can be optimized more?
2355 2005-03-10 Raphael Neider <rneider AT web.de>
2357 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2358 genNearPointerGet): (hopefully) fixed access to bitfields via
2359 pointers (p->bitN = x; and x = p->bitN; failed)
2361 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

2548 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
2549 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
2550 this might fix SIGSEGVs on MinGW...
2551 * src/SDCCopt.c (killDeadCode): restored original behaviour
2552 (volatile operands might get thrown away though)
2554 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

2580 enable global optimizations for entire library source, other
2581 Makefiles in the source tree are also modified to reflect this,
2582 * device/lib/pic16/libc/stdlib/putchar.c (putchar): dummy putchar()
2584 * doc/sdccman.lyx: updated to reflect new changes,

2592 * (pic16_finaliseOptions): when define macro SDCC_MODEL_{SMALL/LARGE}
2593 when calling assembler to reflect memory model used, also define
2594 macro STACK_MODEL_{SMALL/LARGE} when compiling and assembling to
2595 reflect stack model used,
2596 * src/pic16/ralloc.c (pic16_allocDirReg): when operand is allocated

3032 functions, ctype functions and macros and some functions of the
3033 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3034 be extensively tested in the future. Standard disclaimer here.
3035 Library is not automatically build yet. But one can build it by
3036 invoking 'make' inside the libc directory.
3037 * added ADC library under libio. Preliminary version yet.
3039 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

3047 * (pic16_storeForReturn): optimized return of 0,
3048 * (genCmp): experimental code for new genCmp which uses PIC18's
3049 special compare&skip instructions. Initial tests fail some times
3050 with variables grater than 1 byte in size, so new code is disabled,
3051 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3053 * (genCast): began a fix to optimize the casting of a bit to another
3054 bit, now assigning a bitfield to another bitfield will fail, sorry,
3055 * src/pic16/main.c: disabled the use of lr-support feature,
3056 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
3057 * added some function prototypes, added function _debugf prototype,

3059 bits with offset (case PO_GPR_BIT),
3060 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
3062 * (isBankInstruction): modified to return 0 for no banking instruction,
3063 and 1 for banking instruction,
3064 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3065 caused stop processing pCodes after a inline assembly block,
3066 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
3067 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
3068 registers when it shouldn't,
3069 * src/pic16/ralloc.c (allocReg): add preliminary support for
3070 supporting a limited set of temporary registers,
3072 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3077 (loadRegFromAop): recognize CLRH optimization,
3078 (genFunction): optimize RECEIVE iCodes in reentrant functions
3080 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6077 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6079 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6080 loaded with the linker search paths (-L arguments) and the libraries
6081 to be linked with the current source (-l arguments). Changes
6082 currently will affect only the pic16 port.
6083 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6084 include path the port specific paths and port specific libraries,
6085 * gplink command now contains the $3 argument,
6086 * src/pic16/device.h,
6087 * src/pic16/device.c,: structure PIC_device is made public and
6088 renamed to PIC16_device, the same for variable Pics which is renamed

6103 Documenting changes from previous commits.
6104 * configure.in (version 1.56),
6105 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6106 when generating output files to configure the pic16 library,
6107 but now I've commented it out, since gputils aren't installed in the
6108 SF compile farm, so library won't compile
6110 * device/lib/Makefile.in (version 1.56): initially I've added in
6111 target 'all' the prerequestive 'model-pic16' so it compiled the
6112 pic16 library, but now I've commented it out for the same reasons
6114 * added targets 'model-pic16' and 'objects-pic16' to compile the
6116 * added target 'port-specific-objects-pic16' to handle the
6117 generated libraries and copy them into the build/ directory
6118 * added target 'clean-intermediate-pic16' to clean intermediate
6119 files into pic16 directory
6120 * in target 'installdirs' added line to create directory pic16 in
6121 the installation path
6123 * device/include/Makefile.in (version 1.11): in target 'install'
6124 added lines to copy all header files to installation path,
6125 * in target 'installdirs' added line create directory for pic16
6126 headers in the installation path

6171 via literal number. The symbol is placed in the corresponding
6172 position of the data ram
6173 * (pic16_dump_section): relocatable and absolute uninitialized
6174 data are now emitted in sorted order to reduce section naming,
6175 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6176 weren't marked as being in the access bank,
6178 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6180 Added portion of GNU PIC Library under the directory
6181 device/include/pic16 and device/lib/pic16. These files
6182 contain the declarations of SFRs for the PIC18Fxx2 devices.
6183 The directory is initialized via configure from toplevel.
6185 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
6187 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

6213 all over. Telling LaTeX to be less strict with word spacing
6214 to better keep the right margin. Changed some notes about
6215 maintainance of the ports in section 3.2.1 - is it OK like this?
6217 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

6257 * src/pic16/peeph.def: all peepholes with movff are commented out,
6258 because there is a problem in the pcode peep optimizer,
6259 * src/pic16/ralloc.c: the register allocator can now reuse local

6336 2004-01-07 Borut Razem <borut.razem AT siol.net>
6338 * support/scripts/sdcc.nsi: update PATH
6339 * support/scripts/sdcc.ico: craeted

6352 include information about variables allocated to the overlay
6355 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6357 * as/mcs51/lkmain.c: Help about -Y option

6369 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6371 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6372 (default behaviour).
6374 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6376 A python script to validate compiler diagnostic messages. It can be
6377 used to verify that sdcc complains about bad c source code and
6378 gives a good location of the error.
6379 * support/valdiag/Makefile,
6380 * support/valdiag/valdiag.py,
6381 * support/valdiag/tests/*
6383 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6385 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

6396 * src/common.h: added ifndef/define/endif macros
6397 around the header file.
6398 Bug reported from Jesus Calvino-Fraga
6400 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6402 * sdcc.spec: updated
6403 * device/include/Makefile.in: don't install CVS directories
6404 * device/lib/Makefile.in: added removal of CVS directories after install
6405 * doc/Makefile: fixed install, added local_icons
6406 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6407 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6408 * src/ds390/gen.c (genRightShift): fixed bug #870788
6409 * src/SDCCast.c (decorateType): fixed bug #870781
6411 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6413 PIC16 port related changes:
6414 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6415 added variable stackPos,
6417 * gen.c: genCall, assignResultValue: added support for
6418 pushing/retrieving function parameters to/from stack,
6419 genFunction,genEndFunction: setup stack frame for the
6421 genAddrOf: will be changed according to bug 863624
6423 * added files genutils.c and genutils.h which contain gen*
6424 debugged and optimised functions extracted from gen.c
6426 * glue.c: added variable 'externs' which holds extern symbols,
6427 pic16emitRegularMap: is modified to properly handle relocatable
6428 symbols under the new scheme,
6429 pic16createInterruptVect: is modified
6430 pic16printPublics: is modified to emit 'global' assembler directives,
6431 added pic16_printExterns to print extern symbols,
6432 pic16glue: initializes stack/frame pointer in the beginning of
6433 the assembly output. Temporary hack, will be corrected later,
6434 because gplink yet does not support stack and SDCC does not
6435 yet support a type of crt0.o object to create the final binary.
6437 * Removed many lines that contain 8051 legacy code.
6438 * The code is finally placed under a 'code' directive.
6439 * Added port specific options.
6441 * _process_pragma: simplified since now we do not need *special*
6442 include file to define SFR registers. But a separate header
6443 will be needed. This will be developed later.
6444 * _pic16_parseOptions: added, parses port specific options:
6445 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6446 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6447 --preplace-udata-with=
6449 * _pic16_setDefaultOptions: modified to initialize section names,
6450 but hack is temporarly out of order since it needs improvement.
6451 * _pic16_genAssemblerPreamble: configuration words are emitted by
6452 their address instead of their name. This part is incomplete and
6453 supports only the 18Fxx2 devices. Other devices will emit an error
6454 during assembly since they do not contain the same set of config
6456 * _pic16_genIVT: is modified,
6458 * pcode.c: added definitions for some hardware registers that are needed
6460 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6461 All PCI entries are updated. Now LFSR is supported.
6462 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6463 * added pic16_newpCodeOpLit2 to support instructions with
6464 two literal arguments
6465 * pic16_pCode2str: corrected code that emits assembler instructions
6466 with two literal operands and those that have an access bit modifier
6467 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6468 this fixes a bug which caused some labels to be lost, when an
6469 assembler directive was added, i.e. banksel,
6470 * pic16_FixRegisterBanking: improved logic that causes the insertion
6472 * InlineFunction: functions that are called once, are not any more
6473 inlined. This can be a port option in the future,
6475 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6477 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6478 hold the corresponding uninitialized symbols,
6479 * pic16_allocProcessorRegister: registers have explicit marked the
6481 * pic16_allocInternalRegister: registers are explicit marked as
6483 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6484 processing list, so bit registers were lost,
6487 * ralloc.h: added field 'accessBank' and original symbol operand
6488 in register definition,
6489 * removed the field isMapped from register definition,
6491 ** Several functions have been removed from various sources:
6492 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6493 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6494 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6495 pic16_assignRelocatableRegisters
6497 ** others have been introduced:
6498 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6499 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6501 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6503 * support/scripts/inc2h.pl: changed definition of BIT_AT
6504 to emit 'sbit at' instead of 'bit at'. This was a request.
6506 PIC16 port related preliminary changes:
6507 * gen.c: prefixed function popRegFromString with
6508 pic16_ and all references to it corrected
6509 * pcode.c: all pic16_pc_* hardware registers prefixed
6510 with underscore (_),
6511 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6512 * ralloc.c: newReg(): when register is REG_SFR then
6513 set address to rIdx,
6514 pic16_allocProcessorRegister(): marks register wasUsed=0
6515 pic16_writeUsedRegs(): added a call to assign processor
6516 registers via pic16_assignFixedRegisters
6518 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6520 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6521 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6522 variables in unused register banks. Also the SSEG is placed
6523 wherever there is enough space for it, and IDATA can be anywhere
6524 in internal RAM. For now compile using -Wl-Y[stack_size].
6525 The mem file is different for this option as well, since it
6526 makes no sense of talking about DSEG lenght.
6528 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6530 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6531 in certain cases, e.g. when ROM assignment, patch provided
6532 from Albert den Haan.
6534 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7557 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7558 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol

7577 A few small changes that speed up the peephole optimizer.
7581 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7583 Try to make the peephole optimizer smarter by maintaining
7584 an association between the assembly source code and the
7585 iCodes that originated them. Put this information to use
7586 with a new peephole rule condition "notVolatile" so that
7587 the rules can be aggressive yet still safe.
7592 * src/mcs51/peeph.def
7594 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7598 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),

7600 if the left or right operand symbols have the accuse flag set.
7602 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7604 Changed the type of the result of the ! (NOT) operator to char;
7605 previously it returned the same type as the source. This allows
7606 us to eliminate all the genFloatNot functions (all of its target
7607 implementations were very buggy) since !float can use the same
7610 * src/SDCCicode.c (ast2iCode): ! returns char

7619 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7620 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7621 during interrupts. Ensure WSAVE is located at a shared bank address.
7622 2. Fixed page selection in some places
7623 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7624 the registers name strings.
7625 4. Fixed "signed / unsigned compare" compiler warnings.
7626 5. The PIC port manages its own allocation of the general purpose
7627 registers, but makes no attempt to reuse them. As a result when
7628 compiling it soon runs out of general purpose registers. Some
7629 additional code was added to the files pcode.c and device.c to walk
7630 through the function call tree and rename the registers so that they
7640 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

7647 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7649 Made bitfield a distinct type from bit so that bitfields
7650 convert as per ANSI C and bits retain their traditional
7651 boolean style behaviour. Implemented bitfield support in
7659 * src/ds390/gen.c: bit v bitfield split
7660 * src/z80/gen.c: New support for bitfields
7661 * support/regression/tests/bitfields.c: reenabled z80,
7664 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7666 Rules 246.x, 247.x relate to bitfields, the others speed up
7667 access to xdata mapped I/O devices.
7669 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7671 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7673 Cleaned up genPackBits and genUnpackBits and added two helper
7674 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7675 for literal assignments in genPackBits (thanks to Frieder for
7681 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7683 Fixed bug #748310 (pointer to function type mishandled when the
7684 function name is omitted). Also fixed a SIGSEGV when a function
7685 attribute (reentrant, etc) is used on a non-function or on a
7686 function but misplaced before the parameter list.

7713 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7715 Made the constant following the "interrupt" keyword optional. If
7716 omitted, the function will not automatically be given an entry
7717 in the interrupt vector table (similar to #pragma NOIV, but
7718 less syntacticly kludgy). The interrupt number is also now
7719 range checked. Also fixed a bug in the high order bit example

8222 * src/pic16/pcode.c: Cleaned warnings
8223 * src/pic16/pcodeflow.c: Cleaned warnings
8224 * src/pic16/pcoderegs.c: Cleaned warnings
8226 2003-05-19 Scott Dattalo <scott AT dattalo.com>

8237 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
8239 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
8240 it can be defined with CFLAGS when running configure
8241 * src/SDCCmain.c: fixed compiling + linking with object files
8243 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
8245 * configure.in: configure for pic16 port,
8246 added --disable-pic16-port
8247 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
8248 * src/SDCCmain.c: linkOptions is changed to set *,
8249 added if/endif conditional macros to remove options help
8250 messages from optionsTable when a port is not configured, added
8251 support for the PIc16 port in the ports table, when executing
8252 the compiler with no port specified on command line, a default
8253 port is selected with the new macro DEFAULT_PORT which is
8254 defined in port.h, in setDefaultOptions() linkOptions is removed
8255 from initialization assignment, since now it is a set,
8256 parseCmdLine uses setParseWithComma for linkOptions, in
8257 linkEdit() linkOptions are accessed with new function indexSet()
8258 which returns the i'th item of a set variable. See SDCCset.c, in
8259 linkEdit() when calling buildCmdLine(), added linkOptions as
8260 last argument. Now users can pass arguments to gplink via the
8261 -Wl option, main() uses pic16glue() to glue up pic16 programs

8271 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
8273 * src/pic16/glue.c: commented out some error producing lines
8274 * src/pic16/main.c: __config directives are commented out to stop
8275 gpasm complaining and test the linkage with gplink, _linkCmd and
8276 _asmCmd changed to be more gplink and gpasm friendly
8277 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8278 produced an error when parsed, peep rule 12 is added to utilize
8279 movff, but it is commented out since the pCode does not support
8280 yet a command with 2 address arguments
8282 2003-05-18 <johan AT balder>
8284 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8311 2003-05-11 Borut Razem <borut.razem AT siol.net>
8313 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

9302 2003-01-07 <johan AT balder>
9304 * src/SDCCast.c (decorateType): fixed bug #600035

9319 * src/SDCCicode.c: fixed array add
9321 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
9322 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
9323 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9325 2003-01-04 <johan AT balder>
9327 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9329 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9330 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9332 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9333 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

9339 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
9340 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
9342 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9343 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9345 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9347 * in \sdcc\as\mcs51\ changed these files in order to create an
9348 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9349 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9350 following files to include the previous two files: aslink.dsp,
9351 Makefile.aslink, Makefile.bcc, and Makefile.in.
9353 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9354 .adb instead of .cdb
9356 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9358 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9359 value from option --iram-size.
9361 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9363 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9366 2002-09-18 <wiml AT hhhh.org>
9368 * SDCClrange.h: exposed setFromRange() and setToRange()
9369 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9370 packRegsForAccUse() (bug 542397)
9371 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9372 multiple times and emitting the fetch operations more than once
9373 added aopGetUsesAcc() function to allow binary operators to
9374 fetch their operands in the correct order; made genMinus() emit
9375 compact code for X = LITERAL - Y
9377 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9378 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9379 sprintf() in line 1267.
9381 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9382 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9385 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9386 Changes to aslink (All the changes are marked with 'JCF'):
9388 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9391 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9392 area BSEG. Also moves, if possible, the DATA area down into the internal
9393 ram so more space is available.
9395 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9398 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9399 not bytes. Function summary() which creates a memory usage summary
9400 file with extension .mem. Reports of overlaping stack and small stack
9401 size. If the space for the stack is less than 16 bytes aslink trows a
9404 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9405 the 8051. Option 'y' for memory summary output file.
9407 Changes to sdcc (All the changes are marked with 'JCF'):
9409 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9411 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9412 overlaying area for it (uses RegBankUsed[4]).
9414 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9415 bank zero as used by default. By default aslink locates the stack
9416 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9417 the creation of the .mem file. Delegates the allocation of data area
9418 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9419 the begining of the stack area to aslink.
9421 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9422 glue() in SDCCglue.c creates an area for it.
9424 2002-09-03 Borut Razem <borut.razem AT siol.net>
9425 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9426 sdcc/src/pic/glue.c:
9427 introduced atexit() handler for teporay files removal in case of
9428 errors, assertions, ...
9430 2002-08-29 Borut Razem <borut.razem AT siol.net>
9431 * sdcc/support/cpp2/auto-host_vc_in.h:
9432 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9433 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9434 Maybe there is a similar problem with BORLANDC? It should be checked!
9436 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9437 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9438 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9439 was not executed, and the compiler (cl) launched a warning:
9440 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9442 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9443 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9445 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9446 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9448 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9449 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9450 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9451 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9452 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9453 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9454 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9455 - added Release configuration in VS projects
9456 - review of compiler an linker options
9457 - VC .exe files are generated in bin_vc directory, not to interfere
9458 with binaries generated from other projects (cygwin, mingw, bcc ...)
9460 * sdcc/src/yacc.dsp: added
9462 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9463 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9464 and insert the version number definitions from .version
9466 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9468 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9469 added - genarate auto-host.h using auto-host_vc_in.h as template
9472 removed from CVS, generated automatically
9474 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9475 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9477 2002-08-11 Borut Razem <borut.razem AT siol.net>
9478 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9480 2002-08-10 Borut Razem <borut.razem AT siol.net>
9481 * src/SDCCmain.c (main):
9482 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9483 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9484 The consequence was that some temporary files were not removed.
9487 unification of code in functions tempfilename() and tempfile():
9488 function tempnam() is defined in Visual Studio 6.0 and .NET
9490 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9492 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9493 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9494 - removed compiler command line option /WX: Treats all warnings as errors
9495 - update a list of source files, included into the project
9497 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9498 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9499 changed project type to Generic Project so that can be correcly converted to VS.NET project
9501 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9503 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9505 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9507 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9508 added return 0 statements after assert() to make compiler happy
9510 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9511 added newline in the def file to keep MSC compiler satisfied
9513 * sdcc/src/z80/gen.c:
9514 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9515 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9516 - solved MSC error in function aopDump()
