2154 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2156 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
2157 * src/z80/main.c (_keywords[]),
2158 * src/SDCCglobal.h (struct options),
2160 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
2161 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
2162 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
2163 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
2164 always available in leading double underscore form. The C99 support is
2165 mostly missing, but it's a start.
2166 * support/regression/tests/bug-227710.c: fixed nonconforming use of
2167 reserved identifier "__data".
2169 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
2171 * src/mcs51/peeph.def: fixed bug 1170013
2173 2005-03-22 Maarten Brock <sourceforge.brock AT dse.nl>

2179 * src/SDCCcflow.c (dfNumCompare): committed the wrong version of this
2182 2005-03-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2184 * src/port.h (struct PORT),
2185 * src/avr/ralloc.c (avr_assignRegisters),
2187 * src/ds390/ralloc.c (ds390_assignRegisters),
2189 * src/hc08/ralloc.c (hc08_assignRegisters),

2201 * src/SDCCopt.c (eBBlockFromiCode, replaceRegEqv, killDeadCode),
2202 * src/SDCCcse.c (ifxOptimize, cseBBlock, cseAllBlocks),
2204 * src/SDCCdflow.c (computeDataFlow),

2211 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
2212 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
2213 immedDom() returning wrong block; probably fixes bug #1160833)
2215 2005-03-20 Borut Razem <borut.razem AT siol.net>
2217 * support/scripts/inc2h.pl: WIN32 port
2219 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
2221 * device/lib/makefile.in: added abs.c and labs.c
2223 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
2225 * device/include/stdint.h: added
2226 * device/lib/abs.c: added
2227 * device/lib/labs.c: added
2228 * device/include/stdlib.h: added abs() and labs() prototypes
2229 * device/lib/libsdcc.lib: added abs and labs
2230 * device/include/float.h,

2243 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
2245 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2247 * device/lib/printf_large.c: removed inline assembly for portability and
2248 readability. Use printf_fast if speed or size are more important.
2249 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2250 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2252 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2254 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2255 prevent compiler warning
2257 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2259 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2260 moved to level 0 and declared as static. Also they are explicit
2261 placed in access bank. This was necessery because some times they
2262 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2263 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2264 optimizations. Currently only compare to unsigned char is implemented,
2265 * src/pic16/gen.c: added fReturnIdx array,
2266 * (struct resolvedIfx) is moved to gen.h and made public,
2267 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2268 * (aopForSym): added an optimization to directly store in stack of
2269 the operand of a SEND iCode,
2270 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2271 but as registers instead (AOP_REG) using the fReturnIdx array,
2272 * (pic16_freeAsmop): remove the freed register from the
2273 _G.sregsAlloc field,
2274 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2275 a compare of 'WREG',
2276 * (pic16_popGetTempRegCond): changed function prototype, now
2277 function takes also a bitVector argument v which holds the current
2278 set of registers that are allocated for stack access by aopForSym,
2279 registers allocated in aopForSym for accessing stack symbols are not
2280 any more part of the functions usedRegs field,
2281 * (genCall): some times aopOp is called for a stack variable to be
2282 send, aopForSym might perform the push, if this is true make sure
2283 that genCall doesn't push the variable twice by testing _G.resDirect,
2284 * (genFunction): changed testing for unspecified interrupt number
2285 from 256 to INTNO_UNSPEC,
2286 * modified selection scheme of frame pointer generation. Previously
2287 if function did use local registers a frame pointer was generated,
2288 now a frame pointer is generated only if function has arguments
2289 (that need PLUSW2 register access), or has stack arguments, or the
2290 compiler is not instructed to omit the frame pointer,
2291 * (genEndFunction): before restoring local registers that were saved
2292 in the function preamble, also restore the registers that *might*
2293 have been allocated for stack access,
2294 * (genRet): removed some old comments,
2295 * (genCmp, the active (RN's) version): added a call to the
2296 pic16_genCmp_special function to perform the compare with a more
2297 robust and optimized way,
2298 * (genInline): a feature has been added in inline code generation,
2299 which allows a wildcard variable substitution when writing inline
2300 assembly. Code is incomplete and experimental therefore undocumented,
2301 * (genCast): changed order of aopOp for result and right to allow
2302 aopForSym to directly load the result if possible,
2303 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2304 perform an optimized compare on some selected special occasions,
2305 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2306 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2307 generate an IVT any more,
2308 * src/pic16/main.c (pic16_optionsTable): added command line option
2310 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2311 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2313 * src/pic16/NOTES: Raphael Neider added in list of active developers
2314 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2315 jumptable_end to prevent bug #,
2316 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2317 inCond and outCond fields,
2318 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2319 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2320 turn off register spilling,
2321 * (packRegsForOneUse): synced with other ports' versions although it
2322 is not used currently,
2323 * (pic16_packRegisters): added an optimization while reading
2324 structure bitfields, some registers may be saved (malloc code is
2325 decreased by 80 bytes)
2327 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2329 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2330 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2331 this can be optimized more?
2333 2005-03-10 Raphael Neider <rneider AT web.de>
2335 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2336 genNearPointerGet): (hopefully) fixed access to bitfields via
2337 pointers (p->bitN = x; and x = p->bitN; failed)
2339 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

2527 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
2528 this might fix SIGSEGVs on MinGW...
2529 * src/SDCCopt.c (killDeadCode): restored original behaviour
2530 (volatile operands might get thrown away though)
2532 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

2971 Adding support for replacing ljmps with sjmps in jumptables
2972 generated for switch statements. For now you need to set the
2973 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2974 Now 4 algorithms for mcs51 jumptable generation are used:
2975 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2976 addresses loaded pc-relative for up to 112 cases and stack-pushing
2977 target addresses loaded with offset from dptr for up to 256 cases.

3003 Large cummulative patch for pic16 port.
3004 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
3005 to call when a stack overflow occurs,
3006 * (malloc.h): added CVS Id tag,
3007 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3009 * added libc directory. The current version of LibC contains string
3010 functions, ctype functions and macros and some functions of the
3011 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3012 be extensively tested in the future. Standard disclaimer here.
3013 Library is not automatically build yet. But one can build it by
3014 invoking 'make' inside the libc directory.
3015 * added ADC library under libio. Preliminary version yet.
3017 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

3024 * (genUminusFloat): fixed for pic16, ported code from mcs51,
3025 * (pic16_storeForReturn): optimized return of 0,
3026 * (genCmp): experimental code for new genCmp which uses PIC18's
3027 special compare&skip instructions. Initial tests fail some times
3028 with variables grater than 1 byte in size, so new code is disabled,

6055 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6057 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6058 loaded with the linker search paths (-L arguments) and the libraries
6059 to be linked with the current source (-l arguments). Changes
6060 currently will affect only the pic16 port.
6061 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6062 include path the port specific paths and port specific libraries,
6063 * gplink command now contains the $3 argument,
6064 * src/pic16/device.h,
6065 * src/pic16/device.c,: structure PIC_device is made public and
6066 renamed to PIC16_device, the same for variable Pics which is renamed

6081 Documenting changes from previous commits.
6082 * configure.in (version 1.56),
6083 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6084 when generating output files to configure the pic16 library,
6085 but now I've commented it out, since gputils aren't installed in the
6086 SF compile farm, so library won't compile
6088 * device/lib/Makefile.in (version 1.56): initially I've added in
6089 target 'all' the prerequestive 'model-pic16' so it compiled the
6090 pic16 library, but now I've commented it out for the same reasons
6092 * added targets 'model-pic16' and 'objects-pic16' to compile the
6094 * added target 'port-specific-objects-pic16' to handle the
6095 generated libraries and copy them into the build/ directory
6096 * added target 'clean-intermediate-pic16' to clean intermediate
6097 files into pic16 directory
6098 * in target 'installdirs' added line to create directory pic16 in
6099 the installation path
6101 * device/include/Makefile.in (version 1.11): in target 'install'
6102 added lines to copy all header files to installation path,
6103 * in target 'installdirs' added line create directory for pic16
6104 headers in the installation path

6119 * src/z80/main.c (_parseOptions): fixed the portmode= command line
6120 option so that it actually works. Made it specific to the z80, since
6121 the gbz80 doesn't have these kinds of I/O ports.
6123 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6125 * device/include/z180.h,

6149 via literal number. The symbol is placed in the corresponding
6150 position of the data ram
6151 * (pic16_dump_section): relocatable and absolute uninitialized
6152 data are now emitted in sorted order to reduce section naming,
6153 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6154 weren't marked as being in the access bank,
6156 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6158 Added portion of GNU PIC Library under the directory
6159 device/include/pic16 and device/lib/pic16. These files
6160 contain the declarations of SFRs for the PIC18Fxx2 devices.
6161 The directory is initialized via configure from toplevel.
6163 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

6190 * doc/sdccman.lyx: Moved and added some sections, small changes
6191 all over. Telling LaTeX to be less strict with word spacing
6192 to better keep the right margin. Changed some notes about
6193 maintainance of the ports in section 3.2.1 - is it OK like this?
6195 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

6233 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
6235 * src/pic16/peeph.def: all peepholes with movff are commented out,
6236 because there is a problem in the pcode peep optimizer,
6237 * src/pic16/ralloc.c: the register allocator can now reuse local

6274 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6277 * src/z80/main.c: added missed needLinkerScript flags (more than
6278 one port structure defined in these file)
6279 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

6302 directive when no overlay data exist
6303 * (picglue): modified to emit uninitialized data segment
6304 according to udata_section_name

6309 arguments via -W option
6310 * src/pic16/main.c: added $l in _asmCmd, changed extension for
6311 object file from '.rel' to '.o' in port->linker structure,

6314 2004-01-07 Borut Razem <borut.razem AT siol.net>
6316 * support/scripts/sdcc.nsi: update PATH
6317 * support/scripts/sdcc.ico: craeted

6330 include information about variables allocated to the overlay
6333 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6335 * as/mcs51/lkmain.c: Help about -Y option

6347 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6349 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6350 (default behaviour).
6352 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6354 A python script to validate compiler diagnostic messages. It can be
6355 used to verify that sdcc complains about bad c source code and
6356 gives a good location of the error.
6357 * support/valdiag/Makefile,
6358 * support/valdiag/valdiag.py,
6359 * support/valdiag/tests/*
6361 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6375 around the header file.
6376 Bug reported from Jesus Calvino-Fraga
6378 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6380 * sdcc.spec: updated
6381 * device/include/Makefile.in: don't install CVS directories
6382 * device/lib/Makefile.in: added removal of CVS directories after install
6383 * doc/Makefile: fixed install, added local_icons
6384 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6385 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6386 * src/ds390/gen.c (genRightShift): fixed bug #870788
6387 * src/SDCCast.c (decorateType): fixed bug #870781
6389 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6391 PIC16 port related changes:
6392 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6393 added variable stackPos,
6395 * gen.c: genCall, assignResultValue: added support for
6396 pushing/retrieving function parameters to/from stack,
6397 genFunction,genEndFunction: setup stack frame for the
6399 genAddrOf: will be changed according to bug 863624
6401 * added files genutils.c and genutils.h which contain gen*
6402 debugged and optimised functions extracted from gen.c
6404 * glue.c: added variable 'externs' which holds extern symbols,
6405 pic16emitRegularMap: is modified to properly handle relocatable
6406 symbols under the new scheme,
6407 pic16createInterruptVect: is modified
6408 pic16printPublics: is modified to emit 'global' assembler directives,
6409 added pic16_printExterns to print extern symbols,
6410 pic16glue: initializes stack/frame pointer in the beginning of
6411 the assembly output. Temporary hack, will be corrected later,
6412 because gplink yet does not support stack and SDCC does not
6413 yet support a type of crt0.o object to create the final binary.
6415 * Removed many lines that contain 8051 legacy code.
6416 * The code is finally placed under a 'code' directive.
6417 * Added port specific options.
6419 * _process_pragma: simplified since now we do not need *special*
6420 include file to define SFR registers. But a separate header
6421 will be needed. This will be developed later.
6422 * _pic16_parseOptions: added, parses port specific options:
6423 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6424 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6425 --preplace-udata-with=
6427 * _pic16_setDefaultOptions: modified to initialize section names,
6428 but hack is temporarly out of order since it needs improvement.
6429 * _pic16_genAssemblerPreamble: configuration words are emitted by
6430 their address instead of their name. This part is incomplete and
6431 supports only the 18Fxx2 devices. Other devices will emit an error
6432 during assembly since they do not contain the same set of config
6434 * _pic16_genIVT: is modified,
6436 * pcode.c: added definitions for some hardware registers that are needed
6438 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6439 All PCI entries are updated. Now LFSR is supported.
6440 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6441 * added pic16_newpCodeOpLit2 to support instructions with
6442 two literal arguments
6443 * pic16_pCode2str: corrected code that emits assembler instructions
6444 with two literal operands and those that have an access bit modifier
6445 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6446 this fixes a bug which caused some labels to be lost, when an
6447 assembler directive was added, i.e. banksel,
6448 * pic16_FixRegisterBanking: improved logic that causes the insertion
6450 * InlineFunction: functions that are called once, are not any more
6451 inlined. This can be a port option in the future,
6453 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6455 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6456 hold the corresponding uninitialized symbols,
6457 * pic16_allocProcessorRegister: registers have explicit marked the
6459 * pic16_allocInternalRegister: registers are explicit marked as
6461 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6462 processing list, so bit registers were lost,
6465 * ralloc.h: added field 'accessBank' and original symbol operand
6466 in register definition,
6467 * removed the field isMapped from register definition,
6469 ** Several functions have been removed from various sources:
6470 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6471 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6472 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6473 pic16_assignRelocatableRegisters
6475 ** others have been introduced:
6476 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6477 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6479 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6481 * support/scripts/inc2h.pl: changed definition of BIT_AT
6482 to emit 'sbit at' instead of 'bit at'. This was a request.
6484 PIC16 port related preliminary changes:
6485 * gen.c: prefixed function popRegFromString with
6486 pic16_ and all references to it corrected
6487 * pcode.c: all pic16_pc_* hardware registers prefixed
6488 with underscore (_),
6489 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6490 * ralloc.c: newReg(): when register is REG_SFR then
6491 set address to rIdx,
6492 pic16_allocProcessorRegister(): marks register wasUsed=0
6493 pic16_writeUsedRegs(): added a call to assign processor
6494 registers via pic16_assignFixedRegisters
6496 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6498 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6499 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6500 variables in unused register banks. Also the SSEG is placed
6501 wherever there is enough space for it, and IDATA can be anywhere
6502 in internal RAM. For now compile using -Wl-Y[stack_size].
6503 The mem file is different for this option as well, since it
6504 makes no sense of talking about DSEG lenght.
6506 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6508 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6509 in certain cases, e.g. when ROM assignment, patch provided
6510 from Albert den Haan.
6512 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6656 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
6657 (allows non-interrupt and interrupt code to safely compete for a resource
6658 without the non-interrupt code having to disable interrupts)
6660 2003-12-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6662 * src/SDCCicode.c (geniCodeAdd),

6682 2003-12-11 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6684 * src/z80/ralloc.c: set DISABLE_PACK_HL = 1 as a temporary fix to bug #855165

6755 it breaks with bitfields, extern declarations, and gcse analysis.
6756 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
6757 could be assigned through a pointer, so don't complain.

7535 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7536 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol

7555 A few small changes that speed up the peephole optimizer.
7559 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7561 Try to make the peephole optimizer smarter by maintaining
7562 an association between the assembly source code and the
7563 iCodes that originated them. Put this information to use
7564 with a new peephole rule condition "notVolatile" so that
7565 the rules can be aggressive yet still safe.
7570 * src/mcs51/peeph.def
7572 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7576 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7577 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7578 if the left or right operand symbols have the accuse flag set.
7580 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7582 Changed the type of the result of the ! (NOT) operator to char;
7583 previously it returned the same type as the source. This allows
7584 us to eliminate all the genFloatNot functions (all of its target
7585 implementations were very buggy) since !float can use the same
7588 * src/SDCCicode.c (ast2iCode): ! returns char

7597 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7598 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7599 during interrupts. Ensure WSAVE is located at a shared bank address.
7600 2. Fixed page selection in some places
7601 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7602 the registers name strings.
7603 4. Fixed "signed / unsigned compare" compiler warnings.
7604 5. The PIC port manages its own allocation of the general purpose
7605 registers, but makes no attempt to reuse them. As a result when
7606 compiling it soon runs out of general purpose registers. Some
7607 additional code was added to the files pcode.c and device.c to walk
7608 through the function call tree and rename the registers so that they
7618 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

7625 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7627 Made bitfield a distinct type from bit so that bitfields
7628 convert as per ANSI C and bits retain their traditional
7629 boolean style behaviour. Implemented bitfield support in
7637 * src/ds390/gen.c: bit v bitfield split
7638 * src/z80/gen.c: New support for bitfields
7639 * support/regression/tests/bitfields.c: reenabled z80,
7642 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

7652 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7653 for literal assignments in genPackBits (thanks to Frieder for
7659 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7661 Fixed bug #748310 (pointer to function type mishandled when the
7662 function name is omitted). Also fixed a SIGSEGV when a function
7663 attribute (reentrant, etc) is used on a non-function or on a
7664 function but misplaced before the parameter list.

7693 Made the constant following the "interrupt" keyword optional. If
7694 omitted, the function will not automatically be given an entry
7695 in the interrupt vector table (similar to #pragma NOIV, but
7696 less syntacticly kludgy). The interrupt number is also now
7697 range checked. Also fixed a bug in the high order bit example

8219 * src/SDCCmain.c: fixed compiling + linking with object files
8221 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
8223 * configure.in: configure for pic16 port,
8224 added --disable-pic16-port
8225 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
8226 * src/SDCCmain.c: linkOptions is changed to set *,
8227 added if/endif conditional macros to remove options help
8228 messages from optionsTable when a port is not configured, added
8229 support for the PIc16 port in the ports table, when executing
8230 the compiler with no port specified on command line, a default
8231 port is selected with the new macro DEFAULT_PORT which is
8232 defined in port.h, in setDefaultOptions() linkOptions is removed
8233 from initialization assignment, since now it is a set,
8234 parseCmdLine uses setParseWithComma for linkOptions, in
8235 linkEdit() linkOptions are accessed with new function indexSet()
8236 which returns the i'th item of a set variable. See SDCCset.c, in
8237 linkEdit() when calling buildCmdLine(), added linkOptions as
8238 last argument. Now users can pass arguments to gplink via the
8239 -Wl option, main() uses pic16glue() to glue up pic16 programs
8240 * src/SDCCpeeph.c: various changes to support pic16
8241 * src/SDCCset.c: added function void *indexSet(set *, int) to

8249 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
8251 * src/pic16/glue.c: commented out some error producing lines
8252 * src/pic16/main.c: __config directives are commented out to stop
8253 gpasm complaining and test the linkage with gplink, _linkCmd and
8254 _asmCmd changed to be more gplink and gpasm friendly
8255 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8256 produced an error when parsed, peep rule 12 is added to utilize
8257 movff, but it is commented out since the pCode does not support
8258 yet a command with 2 address arguments
8260 2003-05-18 <johan AT balder>

8289 2003-05-11 Borut Razem <borut.razem AT siol.net>
8291 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

9297 * src/SDCCicode.c: fixed array add
9299 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
9300 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
9301 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9303 2003-01-04 <johan AT balder>
9305 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9307 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9308 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9310 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9311 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

9318 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
9320 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9321 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9323 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9325 * in \sdcc\as\mcs51\ changed these files in order to create an
9326 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9327 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9328 following files to include the previous two files: aslink.dsp,
9329 Makefile.aslink, Makefile.bcc, and Makefile.in.
9331 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9332 .adb instead of .cdb
9334 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9336 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9337 value from option --iram-size.
9339 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9341 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9344 2002-09-18 <wiml AT hhhh.org>
9346 * SDCClrange.h: exposed setFromRange() and setToRange()
9347 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9348 packRegsForAccUse() (bug 542397)
9349 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9350 multiple times and emitting the fetch operations more than once
9351 added aopGetUsesAcc() function to allow binary operators to
9352 fetch their operands in the correct order; made genMinus() emit
9353 compact code for X = LITERAL - Y
9355 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9356 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9357 sprintf() in line 1267.
9359 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9360 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9363 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9364 Changes to aslink (All the changes are marked with 'JCF'):
9366 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9369 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9370 area BSEG. Also moves, if possible, the DATA area down into the internal
9371 ram so more space is available.
9373 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9376 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9377 not bytes. Function summary() which creates a memory usage summary
9378 file with extension .mem. Reports of overlaping stack and small stack
9379 size. If the space for the stack is less than 16 bytes aslink trows a
9382 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9383 the 8051. Option 'y' for memory summary output file.
9385 Changes to sdcc (All the changes are marked with 'JCF'):
9387 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9389 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9390 overlaying area for it (uses RegBankUsed[4]).
9392 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9393 bank zero as used by default. By default aslink locates the stack
9394 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9395 the creation of the .mem file. Delegates the allocation of data area
9396 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9397 the begining of the stack area to aslink.
9399 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9400 glue() in SDCCglue.c creates an area for it.
9402 2002-09-03 Borut Razem <borut.razem AT siol.net>
9403 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9404 sdcc/src/pic/glue.c:
9405 introduced atexit() handler for teporay files removal in case of
9406 errors, assertions, ...
9408 2002-08-29 Borut Razem <borut.razem AT siol.net>
9409 * sdcc/support/cpp2/auto-host_vc_in.h:
9410 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9411 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9412 Maybe there is a similar problem with BORLANDC? It should be checked!
9414 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9415 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9416 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9417 was not executed, and the compiler (cl) launched a warning:
9418 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9420 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9421 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9423 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9424 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9426 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9427 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9428 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9429 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9430 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9431 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9432 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9433 - added Release configuration in VS projects
9434 - review of compiler an linker options
9435 - VC .exe files are generated in bin_vc directory, not to interfere
9436 with binaries generated from other projects (cygwin, mingw, bcc ...)
9438 * sdcc/src/yacc.dsp: added
9440 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9441 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9442 and insert the version number definitions from .version
9444 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9446 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9447 added - genarate auto-host.h using auto-host_vc_in.h as template
9450 removed from CVS, generated automatically
9452 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9453 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9455 2002-08-11 Borut Razem <borut.razem AT siol.net>
9456 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9458 2002-08-10 Borut Razem <borut.razem AT siol.net>
9459 * src/SDCCmain.c (main):
9460 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9461 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9462 The consequence was that some temporary files were not removed.
9465 unification of code in functions tempfilename() and tempfile():
9466 function tempnam() is defined in Visual Studio 6.0 and .NET
9468 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9470 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9471 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9472 - removed compiler command line option /WX: Treats all warnings as errors
9473 - update a list of source files, included into the project
9475 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9476 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9477 changed project type to Generic Project so that can be correcly converted to VS.NET project
9479 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9481 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9483 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9485 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9486 added return 0 statements after assert() to make compiler happy
9488 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9489 added newline in the def file to keep MSC compiler satisfied
9491 * sdcc/src/z80/gen.c:
9492 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9493 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9494 - solved MSC error in function aopDump()
9496 * sdcc_vc.h: define PREFIX as "\\sdcc"
9498 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9499 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
9501 2002-06-22 Scott Dattalo <scott AT dattalo.com>
9502 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9503 - Rewrote the register banking algorithm.
9504 - Added pCode live-range analysis to registers (for now, only non-used and
9505 singly-used registers optimized away)
9507 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9509 * support/scripts/inc2h.pl Kevin L. Pauba <klpauba AT cox.net> submitted this perl script for converting MicroChip include files into SDCC Pic include files.
9511 2002-05-10 Scott Dattalo <scott AT dattalo.com>
9512 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
9514 2002-04-22 Michael Hope <michaelh AT vroom>
9516 * device/lib/z80/printf.c: Changed emitter to volatile to work around a pcall bug.
9518 * configure.in (DD_COPT): Added include support required for gbdk.

9522 * src/SDCCmain.c: Added -nostdinc to the default options.
9524 2002-04-15 Michael Hope <michaelh AT vroom>
9526 * device/lib/z80/printf.c (sprintf): Added.
