2148 where not placed in the same memory bank,
2149 * device/lib/pic16/libsdcc/char/: various modifications to improve
2150 library performance,
2151 * doc/sdccman.lyx: some reorganization of the PIC16 part, added many
2152 information on the new functions of the c library and more...
2154 2005-03-28 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2156 * src/SDCCBBlock.c (iCodeBreakDown): fixed bug #1170212
2158 2005-03-26 Raphael Neider <rneider AT web.de>
2160 * src/pic16/gen.c (genSkipc): fixed semantics (execute branch
2161 if condition == CARRY)
2162 * (genCmp): adapted to new genSkipc semantics
2163 * src/pic16/genutils.c (pic6_genCmp_special): removed side effect
2164 on rIfx (genCmp was broken)
2166 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2168 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
2169 * src/z80/main.c (_keywords[]),
2170 * src/SDCCglobal.h (struct options),
2172 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
2173 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
2174 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
2175 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
2176 always available in leading double underscore form. The C99 support is
2177 mostly missing, but it's a start.
2178 * support/regression/tests/bug-227710.c: fixed nonconforming use of
2179 reserved identifier "__data".
2181 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
2183 * src/mcs51/peeph.def: fixed bug 1170013
2185 2005-03-22 Maarten Brock <sourceforge.brock AT dse.nl>

2189 2005-03-21 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2191 * src/SDCCcflow.c (dfNumCompare): committed the wrong version of this
2194 2005-03-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2196 * src/port.h (struct PORT),
2197 * src/avr/ralloc.c (avr_assignRegisters),
2199 * src/ds390/ralloc.c (ds390_assignRegisters),
2201 * src/hc08/ralloc.c (hc08_assignRegisters),

2223 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
2224 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
2225 immedDom() returning wrong block; probably fixes bug #1160833)
2227 2005-03-20 Borut Razem <borut.razem AT siol.net>
2229 * support/scripts/inc2h.pl: WIN32 port
2231 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
2233 * device/lib/makefile.in: added abs.c and labs.c
2235 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
2237 * device/include/stdint.h: added
2238 * device/lib/abs.c: added
2239 * device/lib/labs.c: added
2240 * device/include/stdlib.h: added abs() and labs() prototypes
2241 * device/lib/libsdcc.lib: added abs and labs
2242 * device/include/float.h,

2255 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
2257 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2259 * device/lib/printf_large.c: removed inline assembly for portability and
2260 readability. Use printf_fast if speed or size are more important.
2261 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2262 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2264 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2266 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2267 prevent compiler warning
2269 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2271 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2272 moved to level 0 and declared as static. Also they are explicit
2273 placed in access bank. This was necessery because some times they
2274 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2275 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2276 optimizations. Currently only compare to unsigned char is implemented,
2277 * src/pic16/gen.c: added fReturnIdx array,
2278 * (struct resolvedIfx) is moved to gen.h and made public,
2279 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2280 * (aopForSym): added an optimization to directly store in stack of
2281 the operand of a SEND iCode,
2282 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2283 but as registers instead (AOP_REG) using the fReturnIdx array,
2284 * (pic16_freeAsmop): remove the freed register from the
2285 _G.sregsAlloc field,
2286 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2287 a compare of 'WREG',
2288 * (pic16_popGetTempRegCond): changed function prototype, now
2289 function takes also a bitVector argument v which holds the current
2290 set of registers that are allocated for stack access by aopForSym,
2291 registers allocated in aopForSym for accessing stack symbols are not
2292 any more part of the functions usedRegs field,
2293 * (genCall): some times aopOp is called for a stack variable to be
2294 send, aopForSym might perform the push, if this is true make sure
2295 that genCall doesn't push the variable twice by testing _G.resDirect,
2296 * (genFunction): changed testing for unspecified interrupt number
2297 from 256 to INTNO_UNSPEC,
2298 * modified selection scheme of frame pointer generation. Previously
2299 if function did use local registers a frame pointer was generated,
2300 now a frame pointer is generated only if function has arguments
2301 (that need PLUSW2 register access), or has stack arguments, or the
2302 compiler is not instructed to omit the frame pointer,
2303 * (genEndFunction): before restoring local registers that were saved
2304 in the function preamble, also restore the registers that *might*
2305 have been allocated for stack access,
2306 * (genRet): removed some old comments,
2307 * (genCmp, the active (RN's) version): added a call to the
2308 pic16_genCmp_special function to perform the compare with a more
2309 robust and optimized way,
2310 * (genInline): a feature has been added in inline code generation,
2311 which allows a wildcard variable substitution when writing inline
2312 assembly. Code is incomplete and experimental therefore undocumented,
2313 * (genCast): changed order of aopOp for result and right to allow
2314 aopForSym to directly load the result if possible,
2315 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2316 perform an optimized compare on some selected special occasions,
2317 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2318 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2319 generate an IVT any more,
2320 * src/pic16/main.c (pic16_optionsTable): added command line option
2322 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2323 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2325 * src/pic16/NOTES: Raphael Neider added in list of active developers
2326 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2327 jumptable_end to prevent bug #,
2328 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2329 inCond and outCond fields,
2330 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2331 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2332 turn off register spilling,
2333 * (packRegsForOneUse): synced with other ports' versions although it
2334 is not used currently,
2335 * (pic16_packRegisters): added an optimization while reading
2336 structure bitfields, some registers may be saved (malloc code is
2337 decreased by 80 bytes)
2339 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2341 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2342 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2343 this can be optimized more?
2345 2005-03-10 Raphael Neider <rneider AT web.de>
2347 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2348 genNearPointerGet): (hopefully) fixed access to bitfields via
2349 pointers (p->bitN = x; and x = p->bitN; failed)
2351 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

2538 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
2539 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
2540 this might fix SIGSEGVs on MinGW...
2541 * src/SDCCopt.c (killDeadCode): restored original behaviour
2542 (volatile operands might get thrown away though)
2544 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

6067 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6069 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6070 loaded with the linker search paths (-L arguments) and the libraries
6071 to be linked with the current source (-l arguments). Changes
6072 currently will affect only the pic16 port.
6073 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6074 include path the port specific paths and port specific libraries,
6075 * gplink command now contains the $3 argument,
6076 * src/pic16/device.h,
6077 * src/pic16/device.c,: structure PIC_device is made public and
6078 renamed to PIC16_device, the same for variable Pics which is renamed

6093 Documenting changes from previous commits.
6094 * configure.in (version 1.56),
6095 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6096 when generating output files to configure the pic16 library,
6097 but now I've commented it out, since gputils aren't installed in the
6098 SF compile farm, so library won't compile
6100 * device/lib/Makefile.in (version 1.56): initially I've added in
6101 target 'all' the prerequestive 'model-pic16' so it compiled the
6102 pic16 library, but now I've commented it out for the same reasons
6104 * added targets 'model-pic16' and 'objects-pic16' to compile the
6106 * added target 'port-specific-objects-pic16' to handle the
6107 generated libraries and copy them into the build/ directory
6108 * added target 'clean-intermediate-pic16' to clean intermediate
6109 files into pic16 directory
6110 * in target 'installdirs' added line to create directory pic16 in
6111 the installation path
6113 * device/include/Makefile.in (version 1.11): in target 'install'
6114 added lines to copy all header files to installation path,
6115 * in target 'installdirs' added line create directory for pic16
6116 headers in the installation path

6131 * src/z80/main.c (_parseOptions): fixed the portmode= command line
6132 option so that it actually works. Made it specific to the z80, since
6133 the gbz80 doesn't have these kinds of I/O ports.

6161 via literal number. The symbol is placed in the corresponding
6162 position of the data ram
6163 * (pic16_dump_section): relocatable and absolute uninitialized
6164 data are now emitted in sorted order to reduce section naming,
6165 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6166 weren't marked as being in the access bank,
6168 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6170 Added portion of GNU PIC Library under the directory
6171 device/include/pic16 and device/lib/pic16. These files
6172 contain the declarations of SFRs for the PIC18Fxx2 devices.
6173 The directory is initialized via configure from toplevel.
6175 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

6202 * doc/sdccman.lyx: Moved and added some sections, small changes
6203 all over. Telling LaTeX to be less strict with word spacing
6204 to better keep the right margin. Changed some notes about
6205 maintainance of the ports in section 3.2.1 - is it OK like this?
6207 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

6244 UPPER for immediate operands,
6245 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
6247 * src/pic16/peeph.def: all peepholes with movff are commented out,
6248 because there is a problem in the pcode peep optimizer,
6249 * src/pic16/ralloc.c: the register allocator can now reuse local

6251 * src/pic16/ralloc.h: added flag isLocal in structure regs,
6253 Added file src/pic16/NOTES with information about program writing on
6254 the current port version.

6283 gen51Code): more efficient parameter receive for --model-large
6286 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6289 * src/z80/main.c: added missed needLinkerScript flags (more than
6290 one port structure defined in these file)
6291 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

6297 * src/port.h: added flag needLinkerScript in port->linker
6298 structure to inform whether to create a .lnk file or not,
6306 * src/z80/main.c: changed appropriately to configure
6307 needLinkerScript flag
6309 * src/pic16/gen.c (genAddrOf): fixed bug #863624
6310 * src/pic/glue.c: added variable udata_section_name to
6311 override default uninitialized data segment definition for
6312 devices only with SHAREBANK memory (reported from Erik Epetrich)
6313 * (pic14emitOverlay): modified to emit a commented overlay segment
6314 directive when no overlay data exist
6315 * (picglue): modified to emit uninitialized data segment
6316 according to udata_section_name

6322 * src/pic16/main.c: added $l in _asmCmd, changed extension for
6323 object file from '.rel' to '.o' in port->linker structure,

6326 2004-01-07 Borut Razem <borut.razem AT siol.net>
6328 * support/scripts/sdcc.nsi: update PATH
6329 * support/scripts/sdcc.ico: craeted
6331 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>

6334 * doc/Makefile: fix install
6336 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6338 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
6340 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

6342 include information about variables allocated to the overlay
6345 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6347 * as/mcs51/lkmain.c: Help about -Y option

6359 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6361 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6362 (default behaviour).
6364 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6366 A python script to validate compiler diagnostic messages. It can be
6367 used to verify that sdcc complains about bad c source code and
6368 gives a good location of the error.
6369 * support/valdiag/Makefile,
6370 * support/valdiag/valdiag.py,
6371 * support/valdiag/tests/*
6373 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6375 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
6376 * src/SDCCsymt.c (newEnumType),

6384 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6386 * src/common.h: added ifndef/define/endif macros
6387 around the header file.
6388 Bug reported from Jesus Calvino-Fraga
6390 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6392 * sdcc.spec: updated
6393 * device/include/Makefile.in: don't install CVS directories
6394 * device/lib/Makefile.in: added removal of CVS directories after install
6395 * doc/Makefile: fixed install, added local_icons
6396 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6397 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6398 * src/ds390/gen.c (genRightShift): fixed bug #870788
6399 * src/SDCCast.c (decorateType): fixed bug #870781
6401 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6403 PIC16 port related changes:
6404 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6405 added variable stackPos,
6407 * gen.c: genCall, assignResultValue: added support for
6408 pushing/retrieving function parameters to/from stack,
6409 genFunction,genEndFunction: setup stack frame for the
6411 genAddrOf: will be changed according to bug 863624
6413 * added files genutils.c and genutils.h which contain gen*
6414 debugged and optimised functions extracted from gen.c
6416 * glue.c: added variable 'externs' which holds extern symbols,
6417 pic16emitRegularMap: is modified to properly handle relocatable
6418 symbols under the new scheme,
6419 pic16createInterruptVect: is modified
6420 pic16printPublics: is modified to emit 'global' assembler directives,
6421 added pic16_printExterns to print extern symbols,
6422 pic16glue: initializes stack/frame pointer in the beginning of
6423 the assembly output. Temporary hack, will be corrected later,
6424 because gplink yet does not support stack and SDCC does not
6425 yet support a type of crt0.o object to create the final binary.
6427 * Removed many lines that contain 8051 legacy code.
6428 * The code is finally placed under a 'code' directive.
6429 * Added port specific options.
6431 * _process_pragma: simplified since now we do not need *special*
6432 include file to define SFR registers. But a separate header
6433 will be needed. This will be developed later.
6434 * _pic16_parseOptions: added, parses port specific options:
6435 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6436 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6437 --preplace-udata-with=
6439 * _pic16_setDefaultOptions: modified to initialize section names,
6440 but hack is temporarly out of order since it needs improvement.
6441 * _pic16_genAssemblerPreamble: configuration words are emitted by
6442 their address instead of their name. This part is incomplete and
6443 supports only the 18Fxx2 devices. Other devices will emit an error
6444 during assembly since they do not contain the same set of config
6446 * _pic16_genIVT: is modified,
6448 * pcode.c: added definitions for some hardware registers that are needed
6450 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6451 All PCI entries are updated. Now LFSR is supported.
6452 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6453 * added pic16_newpCodeOpLit2 to support instructions with
6454 two literal arguments
6455 * pic16_pCode2str: corrected code that emits assembler instructions
6456 with two literal operands and those that have an access bit modifier
6457 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6458 this fixes a bug which caused some labels to be lost, when an
6459 assembler directive was added, i.e. banksel,
6460 * pic16_FixRegisterBanking: improved logic that causes the insertion
6462 * InlineFunction: functions that are called once, are not any more
6463 inlined. This can be a port option in the future,
6465 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6467 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6468 hold the corresponding uninitialized symbols,
6469 * pic16_allocProcessorRegister: registers have explicit marked the
6471 * pic16_allocInternalRegister: registers are explicit marked as
6473 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6474 processing list, so bit registers were lost,
6477 * ralloc.h: added field 'accessBank' and original symbol operand
6478 in register definition,
6479 * removed the field isMapped from register definition,
6481 ** Several functions have been removed from various sources:
6482 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6483 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6484 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6485 pic16_assignRelocatableRegisters
6487 ** others have been introduced:
6488 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6489 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6491 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6493 * support/scripts/inc2h.pl: changed definition of BIT_AT
6494 to emit 'sbit at' instead of 'bit at'. This was a request.
6496 PIC16 port related preliminary changes:
6497 * gen.c: prefixed function popRegFromString with
6498 pic16_ and all references to it corrected
6499 * pcode.c: all pic16_pc_* hardware registers prefixed
6500 with underscore (_),
6501 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6502 * ralloc.c: newReg(): when register is REG_SFR then
6503 set address to rIdx,
6504 pic16_allocProcessorRegister(): marks register wasUsed=0
6505 pic16_writeUsedRegs(): added a call to assign processor
6506 registers via pic16_assignFixedRegisters
6508 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6510 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6511 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6512 variables in unused register banks. Also the SSEG is placed
6513 wherever there is enough space for it, and IDATA can be anywhere
6514 in internal RAM. For now compile using -Wl-Y[stack_size].
6515 The mem file is different for this option as well, since it
6516 makes no sense of talking about DSEG lenght.
6518 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6520 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6521 in certain cases, e.g. when ROM assignment, patch provided
6522 from Albert den Haan.
6524 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7547 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7548 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7549 type for bits was changed. It resulted in bit variables becoming

7567 A few small changes that speed up the peephole optimizer.
7571 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7573 Try to make the peephole optimizer smarter by maintaining
7574 an association between the assembly source code and the
7575 iCodes that originated them. Put this information to use
7576 with a new peephole rule condition "notVolatile" so that
7577 the rules can be aggressive yet still safe.
7582 * src/mcs51/peeph.def
7584 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7588 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7589 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7590 if the left or right operand symbols have the accuse flag set.
7592 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7594 Changed the type of the result of the ! (NOT) operator to char;
7595 previously it returned the same type as the source. This allows
7596 us to eliminate all the genFloatNot functions (all of its target
7597 implementations were very buggy) since !float can use the same

7609 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7610 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7611 during interrupts. Ensure WSAVE is located at a shared bank address.
7612 2. Fixed page selection in some places
7613 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7614 the registers name strings.
7615 4. Fixed "signed / unsigned compare" compiler warnings.
7616 5. The PIC port manages its own allocation of the general purpose
7617 registers, but makes no attempt to reuse them. As a result when
7618 compiling it soon runs out of general purpose registers. Some
7619 additional code was added to the files pcode.c and device.c to walk

7706 omitted, the function will not automatically be given an entry
7707 in the interrupt vector table (similar to #pragma NOIV, but
7708 less syntacticly kludgy). The interrupt number is also now
7709 range checked. Also fixed a bug in the high order bit example

8212 * src/pic16/pcode.c: Cleaned warnings
8213 * src/pic16/pcodeflow.c: Cleaned warnings
8214 * src/pic16/pcoderegs.c: Cleaned warnings
8216 2003-05-19 Scott Dattalo <scott AT dattalo.com>
8218 * src/pic16/pcode.c: Cleaned warnings
8219 * src/pic16/pcodepeep.c: Cleaned warnings
8220 * src/pic16/ralloc.c: Cleaned warnings

8224 * doc/sdccman.lyx: fixed bug 739745
8225 * src/pic16/pcode.c (pic16_get_op): fixed warning on alpha
8227 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
8229 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
8230 it can be defined with CFLAGS when running configure
8231 * src/SDCCmain.c: fixed compiling + linking with object files
8233 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
8235 * configure.in: configure for pic16 port,
8236 added --disable-pic16-port
8237 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
8238 * src/SDCCmain.c: linkOptions is changed to set *,
8239 added if/endif conditional macros to remove options help
8240 messages from optionsTable when a port is not configured, added
8241 support for the PIc16 port in the ports table, when executing
8242 the compiler with no port specified on command line, a default
8243 port is selected with the new macro DEFAULT_PORT which is
8244 defined in port.h, in setDefaultOptions() linkOptions is removed
8245 from initialization assignment, since now it is a set,
8246 parseCmdLine uses setParseWithComma for linkOptions, in
8247 linkEdit() linkOptions are accessed with new function indexSet()
8248 which returns the i'th item of a set variable. See SDCCset.c, in
8249 linkEdit() when calling buildCmdLine(), added linkOptions as
8250 last argument. Now users can pass arguments to gplink via the
8251 -Wl option, main() uses pic16glue() to glue up pic16 programs
8252 * src/SDCCpeeph.c: various changes to support pic16
8253 * src/SDCCset.c: added function void *indexSet(set *, int) to
8254 return the i'th item of the set

8259 added macro DEFAULT_PORT
8260 * src/pic/main.c: corrected arguments of gplnk in _linkCmd
8261 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
8263 * src/pic16/glue.c: commented out some error producing lines
8264 * src/pic16/main.c: __config directives are commented out to stop
8265 gpasm complaining and test the linkage with gplink, _linkCmd and
8266 _asmCmd changed to be more gplink and gpasm friendly
8267 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8268 produced an error when parsed, peep rule 12 is added to utilize
8269 movff, but it is commented out since the pCode does not support
8270 yet a command with 2 address arguments
8272 2003-05-18 <johan AT balder>
8274 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
8275 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8299 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
8301 2003-05-11 Borut Razem <borut.razem AT siol.net>
8303 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
8304 the path of bin directory, so that PATH is the only env. variable, which has to be set

9309 * src/SDCCicode.c: fixed array add
9311 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
9312 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
9313 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9315 2003-01-04 <johan AT balder>
9317 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9319 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9320 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9322 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

9329 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
9330 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
9332 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9333 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9335 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9337 * in \sdcc\as\mcs51\ changed these files in order to create an
9338 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9339 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9340 following files to include the previous two files: aslink.dsp,
9341 Makefile.aslink, Makefile.bcc, and Makefile.in.
9343 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9344 .adb instead of .cdb
9346 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9348 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9349 value from option --iram-size.
9351 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9353 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9356 2002-09-18 <wiml AT hhhh.org>
9358 * SDCClrange.h: exposed setFromRange() and setToRange()
9359 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9360 packRegsForAccUse() (bug 542397)
9361 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9362 multiple times and emitting the fetch operations more than once
9363 added aopGetUsesAcc() function to allow binary operators to
9364 fetch their operands in the correct order; made genMinus() emit
9365 compact code for X = LITERAL - Y
9367 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9368 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9369 sprintf() in line 1267.
9371 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9372 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9375 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9376 Changes to aslink (All the changes are marked with 'JCF'):
9378 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9381 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9382 area BSEG. Also moves, if possible, the DATA area down into the internal
9383 ram so more space is available.
9385 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9388 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9389 not bytes. Function summary() which creates a memory usage summary
9390 file with extension .mem. Reports of overlaping stack and small stack
9391 size. If the space for the stack is less than 16 bytes aslink trows a
9394 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9395 the 8051. Option 'y' for memory summary output file.
9397 Changes to sdcc (All the changes are marked with 'JCF'):
9399 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9401 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9402 overlaying area for it (uses RegBankUsed[4]).
9404 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9405 bank zero as used by default. By default aslink locates the stack
9406 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9407 the creation of the .mem file. Delegates the allocation of data area
9408 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9409 the begining of the stack area to aslink.
9411 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9412 glue() in SDCCglue.c creates an area for it.
9414 2002-09-03 Borut Razem <borut.razem AT siol.net>
9415 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9416 sdcc/src/pic/glue.c:
9417 introduced atexit() handler for teporay files removal in case of
9418 errors, assertions, ...
9420 2002-08-29 Borut Razem <borut.razem AT siol.net>
9421 * sdcc/support/cpp2/auto-host_vc_in.h:
9422 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9423 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9424 Maybe there is a similar problem with BORLANDC? It should be checked!
9426 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9427 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9428 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9429 was not executed, and the compiler (cl) launched a warning:
9430 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9432 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9433 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9435 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9436 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9438 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9439 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9440 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9441 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9442 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9443 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9444 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9445 - added Release configuration in VS projects
9446 - review of compiler an linker options
9447 - VC .exe files are generated in bin_vc directory, not to interfere
9448 with binaries generated from other projects (cygwin, mingw, bcc ...)
9450 * sdcc/src/yacc.dsp: added
9452 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9453 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9454 and insert the version number definitions from .version
9456 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9458 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9459 added - genarate auto-host.h using auto-host_vc_in.h as template
9462 removed from CVS, generated automatically
9464 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9465 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9467 2002-08-11 Borut Razem <borut.razem AT siol.net>
9468 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9470 2002-08-10 Borut Razem <borut.razem AT siol.net>
9471 * src/SDCCmain.c (main):
9472 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9473 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9474 The consequence was that some temporary files were not removed.
9477 unification of code in functions tempfilename() and tempfile():
9478 function tempnam() is defined in Visual Studio 6.0 and .NET
9480 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9482 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9483 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9484 - removed compiler command line option /WX: Treats all warnings as errors
9485 - update a list of source files, included into the project
9487 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9488 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9489 changed project type to Generic Project so that can be correcly converted to VS.NET project
9491 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9493 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9495 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9497 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9498 added return 0 statements after assert() to make compiler happy
9500 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9501 added newline in the def file to keep MSC compiler satisfied
9503 * sdcc/src/z80/gen.c:
9504 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9505 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9506 - solved MSC error in function aopDump()
9508 * sdcc_vc.h: define PREFIX as "\\sdcc"
9510 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9511 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
9513 2002-06-22 Scott Dattalo <scott AT dattalo.com>
9514 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9515 - Rewrote the register banking algorithm.
