2150 * device/lib/pic16/libc/delay/: NEW, c sources for the delay functions,
2151 * device/lib/pic16/libc/utils/: minor modifications in the .S sources,
2152 * device/lib/pic16/startup/{crt0i.c, crt0iz.c}: redesign of the
2153 _do_cinit function, because the previous failed when local variables
2154 where not placed in the same memory bank,
2155 * device/lib/pic16/libsdcc/char/: various modifications to improve
2156 library performance,
2157 * doc/sdccman.lyx: some reorganization of the PIC16 part, added many
2158 information on the new functions of the c library and more...
2160 2005-03-28 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

2168 * (genCmp): adapted to new genSkipc semantics
2169 * src/pic16/genutils.c (pic6_genCmp_special): removed side effect
2170 on rIfx (genCmp was broken)
2172 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2174 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
2175 * src/z80/main.c (_keywords[]),
2176 * src/SDCCglobal.h (struct options),
2178 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
2179 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
2180 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
2181 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
2182 always available in leading double underscore form. The C99 support is
2183 mostly missing, but it's a start.
2184 * support/regression/tests/bug-227710.c: fixed nonconforming use of
2185 reserved identifier "__data".
2187 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
2189 * src/mcs51/peeph.def: fixed bug 1170013

2231 immedDom() returning wrong block; probably fixes bug #1160833)
2233 2005-03-20 Borut Razem <borut.razem AT siol.net>
2235 * support/scripts/inc2h.pl: WIN32 port
2237 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
2239 * device/lib/makefile.in: added abs.c and labs.c
2241 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
2243 * device/include/stdint.h: added
2244 * device/lib/abs.c: added
2245 * device/lib/labs.c: added
2246 * device/include/stdlib.h: added abs() and labs() prototypes

2263 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2265 * device/lib/printf_large.c: removed inline assembly for portability and
2266 readability. Use printf_fast if speed or size are more important.
2267 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2268 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2270 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2272 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2273 prevent compiler warning
2275 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2277 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2278 moved to level 0 and declared as static. Also they are explicit
2279 placed in access bank. This was necessery because some times they
2280 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2281 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2282 optimizations. Currently only compare to unsigned char is implemented,
2283 * src/pic16/gen.c: added fReturnIdx array,
2284 * (struct resolvedIfx) is moved to gen.h and made public,
2285 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2286 * (aopForSym): added an optimization to directly store in stack of
2287 the operand of a SEND iCode,
2288 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2289 but as registers instead (AOP_REG) using the fReturnIdx array,
2290 * (pic16_freeAsmop): remove the freed register from the
2291 _G.sregsAlloc field,
2292 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2293 a compare of 'WREG',
2294 * (pic16_popGetTempRegCond): changed function prototype, now
2295 function takes also a bitVector argument v which holds the current
2296 set of registers that are allocated for stack access by aopForSym,
2297 registers allocated in aopForSym for accessing stack symbols are not
2298 any more part of the functions usedRegs field,
2299 * (genCall): some times aopOp is called for a stack variable to be
2300 send, aopForSym might perform the push, if this is true make sure
2301 that genCall doesn't push the variable twice by testing _G.resDirect,
2302 * (genFunction): changed testing for unspecified interrupt number
2303 from 256 to INTNO_UNSPEC,
2304 * modified selection scheme of frame pointer generation. Previously
2305 if function did use local registers a frame pointer was generated,
2306 now a frame pointer is generated only if function has arguments
2307 (that need PLUSW2 register access), or has stack arguments, or the
2308 compiler is not instructed to omit the frame pointer,
2309 * (genEndFunction): before restoring local registers that were saved
2310 in the function preamble, also restore the registers that *might*
2311 have been allocated for stack access,
2312 * (genRet): removed some old comments,
2313 * (genCmp, the active (RN's) version): added a call to the
2314 pic16_genCmp_special function to perform the compare with a more
2315 robust and optimized way,
2316 * (genInline): a feature has been added in inline code generation,
2317 which allows a wildcard variable substitution when writing inline
2318 assembly. Code is incomplete and experimental therefore undocumented,
2319 * (genCast): changed order of aopOp for result and right to allow
2320 aopForSym to directly load the result if possible,
2321 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2322 perform an optimized compare on some selected special occasions,
2323 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2324 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2325 generate an IVT any more,
2326 * src/pic16/main.c (pic16_optionsTable): added command line option
2328 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2329 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2331 * src/pic16/NOTES: Raphael Neider added in list of active developers
2332 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2333 jumptable_end to prevent bug #,
2334 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2335 inCond and outCond fields,
2336 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2337 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2338 turn off register spilling,
2339 * (packRegsForOneUse): synced with other ports' versions although it
2340 is not used currently,
2341 * (pic16_packRegisters): added an optimization while reading
2342 structure bitfields, some registers may be saved (malloc code is
2343 decreased by 80 bytes)
2345 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2347 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2348 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2349 this can be optimized more?
2351 2005-03-10 Raphael Neider <rneider AT web.de>
2353 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2354 genNearPointerGet): (hopefully) fixed access to bitfields via
2355 pointers (p->bitN = x; and x = p->bitN; failed)
2357 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

2544 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
2545 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
2546 this might fix SIGSEGVs on MinGW...
2547 * src/SDCCopt.c (killDeadCode): restored original behaviour
2548 (volatile operands might get thrown away though)
2550 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

2590 macro STACK_MODEL_{SMALL/LARGE} when compiling and assembling to
2591 reflect stack model used,
2592 * src/pic16/ralloc.c (pic16_allocDirReg): when operand is allocated

3030 be extensively tested in the future. Standard disclaimer here.
3031 Library is not automatically build yet. But one can build it by
3032 invoking 'make' inside the libc directory.

3047 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3049 * (genCast): began a fix to optimize the casting of a bit to another
3050 bit, now assigning a bitfield to another bitfield will fail, sorry,

6073 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6075 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6076 loaded with the linker search paths (-L arguments) and the libraries
6077 to be linked with the current source (-l arguments). Changes
6078 currently will affect only the pic16 port.
6079 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6080 include path the port specific paths and port specific libraries,
6081 * gplink command now contains the $3 argument,
6082 * src/pic16/device.h,
6083 * src/pic16/device.c,: structure PIC_device is made public and
6084 renamed to PIC16_device, the same for variable Pics which is renamed

6099 Documenting changes from previous commits.
6100 * configure.in (version 1.56),
6101 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6102 when generating output files to configure the pic16 library,
6103 but now I've commented it out, since gputils aren't installed in the
6104 SF compile farm, so library won't compile
6106 * device/lib/Makefile.in (version 1.56): initially I've added in
6107 target 'all' the prerequestive 'model-pic16' so it compiled the
6108 pic16 library, but now I've commented it out for the same reasons
6110 * added targets 'model-pic16' and 'objects-pic16' to compile the
6112 * added target 'port-specific-objects-pic16' to handle the
6113 generated libraries and copy them into the build/ directory
6114 * added target 'clean-intermediate-pic16' to clean intermediate
6115 files into pic16 directory
6116 * in target 'installdirs' added line to create directory pic16 in
6117 the installation path
6119 * device/include/Makefile.in (version 1.11): in target 'install'
6120 added lines to copy all header files to installation path,
6121 * in target 'installdirs' added line create directory for pic16
6122 headers in the installation path

6137 * src/z80/main.c (_parseOptions): fixed the portmode= command line
6138 option so that it actually works. Made it specific to the z80, since
6139 the gbz80 doesn't have these kinds of I/O ports.

6167 via literal number. The symbol is placed in the corresponding
6168 position of the data ram
6169 * (pic16_dump_section): relocatable and absolute uninitialized
6170 data are now emitted in sorted order to reduce section naming,
6171 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6172 weren't marked as being in the access bank,
6174 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6176 Added portion of GNU PIC Library under the directory
6177 device/include/pic16 and device/lib/pic16. These files
6178 contain the declarations of SFRs for the PIC18Fxx2 devices.
6179 The directory is initialized via configure from toplevel.
6181 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
6183 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
6184 the spilllocations to be compared correctly

6208 * doc/sdccman.lyx: Moved and added some sections, small changes
6209 all over. Telling LaTeX to be less strict with word spacing
6210 to better keep the right margin. Changed some notes about
6211 maintainance of the ports in section 3.2.1 - is it OK like this?
6213 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

6251 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
6253 * src/pic16/peeph.def: all peepholes with movff are commented out,
6254 because there is a problem in the pcode peep optimizer,
6255 * src/pic16/ralloc.c: the register allocator can now reuse local

6257 * src/pic16/ralloc.h: added flag isLocal in structure regs,
6259 Added file src/pic16/NOTES with information about program writing on
6260 the current port version.

6292 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6295 * src/z80/main.c: added missed needLinkerScript flags (more than
6296 one port structure defined in these file)
6297 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

6319 * (pic14emitOverlay): modified to emit a commented overlay segment
6320 directive when no overlay data exist
6321 * (picglue): modified to emit uninitialized data segment
6322 according to udata_section_name

6332 2004-01-07 Borut Razem <borut.razem AT siol.net>
6334 * support/scripts/sdcc.nsi: update PATH
6335 * support/scripts/sdcc.ico: craeted

6342 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6344 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
6346 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

6348 include information about variables allocated to the overlay
6351 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6353 * as/mcs51/lkmain.c: Help about -Y option

6365 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6367 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6368 (default behaviour).
6370 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6372 A python script to validate compiler diagnostic messages. It can be
6373 used to verify that sdcc complains about bad c source code and
6374 gives a good location of the error.
6375 * support/valdiag/Makefile,
6376 * support/valdiag/valdiag.py,
6377 * support/valdiag/tests/*
6379 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6381 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

6392 * src/common.h: added ifndef/define/endif macros
6393 around the header file.
6394 Bug reported from Jesus Calvino-Fraga
6396 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6398 * sdcc.spec: updated
6399 * device/include/Makefile.in: don't install CVS directories
6400 * device/lib/Makefile.in: added removal of CVS directories after install
6401 * doc/Makefile: fixed install, added local_icons
6402 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6403 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6404 * src/ds390/gen.c (genRightShift): fixed bug #870788
6405 * src/SDCCast.c (decorateType): fixed bug #870781
6407 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6409 PIC16 port related changes:
6410 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6411 added variable stackPos,
6413 * gen.c: genCall, assignResultValue: added support for
6414 pushing/retrieving function parameters to/from stack,
6415 genFunction,genEndFunction: setup stack frame for the
6417 genAddrOf: will be changed according to bug 863624
6419 * added files genutils.c and genutils.h which contain gen*
6420 debugged and optimised functions extracted from gen.c
6422 * glue.c: added variable 'externs' which holds extern symbols,
6423 pic16emitRegularMap: is modified to properly handle relocatable
6424 symbols under the new scheme,
6425 pic16createInterruptVect: is modified
6426 pic16printPublics: is modified to emit 'global' assembler directives,
6427 added pic16_printExterns to print extern symbols,
6428 pic16glue: initializes stack/frame pointer in the beginning of
6429 the assembly output. Temporary hack, will be corrected later,
6430 because gplink yet does not support stack and SDCC does not
6431 yet support a type of crt0.o object to create the final binary.
6433 * Removed many lines that contain 8051 legacy code.
6434 * The code is finally placed under a 'code' directive.
6435 * Added port specific options.
6437 * _process_pragma: simplified since now we do not need *special*
6438 include file to define SFR registers. But a separate header
6439 will be needed. This will be developed later.
6440 * _pic16_parseOptions: added, parses port specific options:
6441 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6442 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6443 --preplace-udata-with=
6445 * _pic16_setDefaultOptions: modified to initialize section names,
6446 but hack is temporarly out of order since it needs improvement.
6447 * _pic16_genAssemblerPreamble: configuration words are emitted by
6448 their address instead of their name. This part is incomplete and
6449 supports only the 18Fxx2 devices. Other devices will emit an error
6450 during assembly since they do not contain the same set of config
6452 * _pic16_genIVT: is modified,
6454 * pcode.c: added definitions for some hardware registers that are needed
6456 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6457 All PCI entries are updated. Now LFSR is supported.
6458 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6459 * added pic16_newpCodeOpLit2 to support instructions with
6460 two literal arguments
6461 * pic16_pCode2str: corrected code that emits assembler instructions
6462 with two literal operands and those that have an access bit modifier
6463 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6464 this fixes a bug which caused some labels to be lost, when an
6465 assembler directive was added, i.e. banksel,
6466 * pic16_FixRegisterBanking: improved logic that causes the insertion
6468 * InlineFunction: functions that are called once, are not any more
6469 inlined. This can be a port option in the future,
6471 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6473 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6474 hold the corresponding uninitialized symbols,
6475 * pic16_allocProcessorRegister: registers have explicit marked the
6477 * pic16_allocInternalRegister: registers are explicit marked as
6479 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6480 processing list, so bit registers were lost,
6483 * ralloc.h: added field 'accessBank' and original symbol operand
6484 in register definition,
6485 * removed the field isMapped from register definition,
6487 ** Several functions have been removed from various sources:
6488 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6489 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6490 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6491 pic16_assignRelocatableRegisters
6493 ** others have been introduced:
6494 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6495 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6497 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6499 * support/scripts/inc2h.pl: changed definition of BIT_AT
6500 to emit 'sbit at' instead of 'bit at'. This was a request.
6502 PIC16 port related preliminary changes:
6503 * gen.c: prefixed function popRegFromString with
6504 pic16_ and all references to it corrected
6505 * pcode.c: all pic16_pc_* hardware registers prefixed
6506 with underscore (_),
6507 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6508 * ralloc.c: newReg(): when register is REG_SFR then
6509 set address to rIdx,
6510 pic16_allocProcessorRegister(): marks register wasUsed=0
6511 pic16_writeUsedRegs(): added a call to assign processor
6512 registers via pic16_assignFixedRegisters
6514 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6516 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6517 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6518 variables in unused register banks. Also the SSEG is placed
6519 wherever there is enough space for it, and IDATA can be anywhere
6520 in internal RAM. For now compile using -Wl-Y[stack_size].
6521 The mem file is different for this option as well, since it
6522 makes no sense of talking about DSEG lenght.
6524 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6526 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6527 in certain cases, e.g. when ROM assignment, patch provided
6528 from Albert den Haan.
6530 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7553 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7554 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol

7573 A few small changes that speed up the peephole optimizer.
7577 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7579 Try to make the peephole optimizer smarter by maintaining
7580 an association between the assembly source code and the
7581 iCodes that originated them. Put this information to use
7582 with a new peephole rule condition "notVolatile" so that
7583 the rules can be aggressive yet still safe.
7588 * src/mcs51/peeph.def
7590 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7594 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),

7596 if the left or right operand symbols have the accuse flag set.
7598 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7600 Changed the type of the result of the ! (NOT) operator to char;
7601 previously it returned the same type as the source. This allows
7602 us to eliminate all the genFloatNot functions (all of its target
7603 implementations were very buggy) since !float can use the same
7606 * src/SDCCicode.c (ast2iCode): ! returns char

7608 * src/ds390/gen.c (genNot, genNotFloat),
7609 * src/z80/gen.c (genNot, genNotFloat),
7610 * src/pic/gen.c (genNot, genNotFloat),

7615 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7616 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7617 during interrupts. Ensure WSAVE is located at a shared bank address.
7618 2. Fixed page selection in some places
7619 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7620 the registers name strings.
7621 4. Fixed "signed / unsigned compare" compiler warnings.
7622 5. The PIC port manages its own allocation of the general purpose
7623 registers, but makes no attempt to reuse them. As a result when
7624 compiling it soon runs out of general purpose registers. Some
7625 additional code was added to the files pcode.c and device.c to walk
7626 through the function call tree and rename the registers so that they
7636 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

7643 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7645 Made bitfield a distinct type from bit so that bitfields
7646 convert as per ANSI C and bits retain their traditional
7647 boolean style behaviour. Implemented bitfield support in
7655 * src/ds390/gen.c: bit v bitfield split
7656 * src/z80/gen.c: New support for bitfields
7657 * support/regression/tests/bitfields.c: reenabled z80,
7660 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7662 Rules 246.x, 247.x relate to bitfields, the others speed up
7663 access to xdata mapped I/O devices.
7665 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7667 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7669 Cleaned up genPackBits and genUnpackBits and added two helper
7670 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7671 for literal assignments in genPackBits (thanks to Frieder for
7677 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7679 Fixed bug #748310 (pointer to function type mishandled when the
7680 function name is omitted). Also fixed a SIGSEGV when a function
7681 attribute (reentrant, etc) is used on a non-function or on a
7682 function but misplaced before the parameter list.

7709 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7711 Made the constant following the "interrupt" keyword optional. If
7712 omitted, the function will not automatically be given an entry
7713 in the interrupt vector table (similar to #pragma NOIV, but
7714 less syntacticly kludgy). The interrupt number is also now
7715 range checked. Also fixed a bug in the high order bit example

8218 * src/pic16/pcode.c: Cleaned warnings
8219 * src/pic16/pcodeflow.c: Cleaned warnings
8220 * src/pic16/pcoderegs.c: Cleaned warnings
8222 2003-05-19 Scott Dattalo <scott AT dattalo.com>
8224 * src/pic16/pcode.c: Cleaned warnings
8225 * src/pic16/pcodepeep.c: Cleaned warnings

8233 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
8235 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
8236 it can be defined with CFLAGS when running configure
8237 * src/SDCCmain.c: fixed compiling + linking with object files
8239 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
8241 * configure.in: configure for pic16 port,
8242 added --disable-pic16-port
8243 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
8244 * src/SDCCmain.c: linkOptions is changed to set *,
8245 added if/endif conditional macros to remove options help
8246 messages from optionsTable when a port is not configured, added
8247 support for the PIc16 port in the ports table, when executing
8248 the compiler with no port specified on command line, a default
8249 port is selected with the new macro DEFAULT_PORT which is
8250 defined in port.h, in setDefaultOptions() linkOptions is removed
8251 from initialization assignment, since now it is a set,
8252 parseCmdLine uses setParseWithComma for linkOptions, in
8253 linkEdit() linkOptions are accessed with new function indexSet()
8254 which returns the i'th item of a set variable. See SDCCset.c, in
8255 linkEdit() when calling buildCmdLine(), added linkOptions as
8256 last argument. Now users can pass arguments to gplink via the
8257 -Wl option, main() uses pic16glue() to glue up pic16 programs
8258 * src/SDCCpeeph.c: various changes to support pic16
8259 * src/SDCCset.c: added function void *indexSet(set *, int) to

8267 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
8269 * src/pic16/glue.c: commented out some error producing lines
8270 * src/pic16/main.c: __config directives are commented out to stop
8271 gpasm complaining and test the linkage with gplink, _linkCmd and
8272 _asmCmd changed to be more gplink and gpasm friendly
8273 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8274 produced an error when parsed, peep rule 12 is added to utilize
8275 movff, but it is commented out since the pCode does not support
8276 yet a command with 2 address arguments
8278 2003-05-18 <johan AT balder>
8280 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8307 2003-05-11 Borut Razem <borut.razem AT siol.net>
8309 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
8310 the path of bin directory, so that PATH is the only env. variable, which has to be set

9298 2003-01-07 <johan AT balder>
9300 * src/SDCCast.c (decorateType): fixed bug #600035

9315 * src/SDCCicode.c: fixed array add
9317 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
9318 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
9319 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9321 2003-01-04 <johan AT balder>
9323 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9325 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9326 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9328 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9329 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

9335 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
9336 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
9338 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9339 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9341 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9343 * in \sdcc\as\mcs51\ changed these files in order to create an
9344 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9345 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9346 following files to include the previous two files: aslink.dsp,
9347 Makefile.aslink, Makefile.bcc, and Makefile.in.
9349 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9350 .adb instead of .cdb
9352 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9354 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9355 value from option --iram-size.
9357 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9359 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9362 2002-09-18 <wiml AT hhhh.org>
9364 * SDCClrange.h: exposed setFromRange() and setToRange()
9365 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9366 packRegsForAccUse() (bug 542397)
9367 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9368 multiple times and emitting the fetch operations more than once
9369 added aopGetUsesAcc() function to allow binary operators to
9370 fetch their operands in the correct order; made genMinus() emit
9371 compact code for X = LITERAL - Y
9373 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9374 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9375 sprintf() in line 1267.
9377 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9378 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9381 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9382 Changes to aslink (All the changes are marked with 'JCF'):
9384 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9387 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9388 area BSEG. Also moves, if possible, the DATA area down into the internal
9389 ram so more space is available.
9391 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9394 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9395 not bytes. Function summary() which creates a memory usage summary
9396 file with extension .mem. Reports of overlaping stack and small stack
9397 size. If the space for the stack is less than 16 bytes aslink trows a
9400 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9401 the 8051. Option 'y' for memory summary output file.
9403 Changes to sdcc (All the changes are marked with 'JCF'):
9405 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9407 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9408 overlaying area for it (uses RegBankUsed[4]).
9410 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9411 bank zero as used by default. By default aslink locates the stack
9412 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9413 the creation of the .mem file. Delegates the allocation of data area
9414 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9415 the begining of the stack area to aslink.
9417 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9418 glue() in SDCCglue.c creates an area for it.
9420 2002-09-03 Borut Razem <borut.razem AT siol.net>
9421 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9422 sdcc/src/pic/glue.c:
9423 introduced atexit() handler for teporay files removal in case of
9424 errors, assertions, ...
9426 2002-08-29 Borut Razem <borut.razem AT siol.net>
9427 * sdcc/support/cpp2/auto-host_vc_in.h:
9428 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9429 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9430 Maybe there is a similar problem with BORLANDC? It should be checked!
9432 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9433 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9434 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9435 was not executed, and the compiler (cl) launched a warning:
9436 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9438 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9439 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9441 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9442 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9444 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9445 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9446 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9447 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9448 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9449 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9450 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9451 - added Release configuration in VS projects
9452 - review of compiler an linker options
9453 - VC .exe files are generated in bin_vc directory, not to interfere
9454 with binaries generated from other projects (cygwin, mingw, bcc ...)
9456 * sdcc/src/yacc.dsp: added
9458 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9459 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9460 and insert the version number definitions from .version
9462 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9464 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9465 added - genarate auto-host.h using auto-host_vc_in.h as template
9468 removed from CVS, generated automatically
9470 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9471 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9473 2002-08-11 Borut Razem <borut.razem AT siol.net>
9474 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9476 2002-08-10 Borut Razem <borut.razem AT siol.net>
9477 * src/SDCCmain.c (main):
9478 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9479 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9480 The consequence was that some temporary files were not removed.
9483 unification of code in functions tempfilename() and tempfile():
9484 function tempnam() is defined in Visual Studio 6.0 and .NET
9486 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9488 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9489 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9490 - removed compiler command line option /WX: Treats all warnings as errors
9491 - update a list of source files, included into the project
9493 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9494 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9495 changed project type to Generic Project so that can be correcly converted to VS.NET project
9497 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9499 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9501 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9503 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9504 added return 0 statements after assert() to make compiler happy
9506 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9507 added newline in the def file to keep MSC compiler satisfied
9509 * sdcc/src/z80/gen.c:
9510 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9511 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9512 - solved MSC error in function aopDump()
