2198 2005-03-20 Borut Razem <borut.razem AT siol.net>
2200 * support/scripts/inc2h.pl: WIN32 port
2202 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
2204 * device/lib/makefile.in: added abs.c and labs.c
2206 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
2208 * device/include/stdint.h: added
2209 * device/lib/abs.c: added
2210 * device/lib/labs.c: added
2211 * device/include/stdlib.h: added abs() and labs() prototypes

2218 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2220 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed

2226 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
2228 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2230 * device/lib/printf_large.c: removed inline assembly for portability and
2231 readability. Use printf_fast if speed or size are more important.
2232 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2233 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2235 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2237 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2238 prevent compiler warning
2240 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2242 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2243 moved to level 0 and declared as static. Also they are explicit
2244 placed in access bank. This was necessery because some times they
2245 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2246 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2247 optimizations. Currently only compare to unsigned char is implemented,
2248 * src/pic16/gen.c: added fReturnIdx array,
2249 * (struct resolvedIfx) is moved to gen.h and made public,
2250 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2251 * (aopForSym): added an optimization to directly store in stack of
2252 the operand of a SEND iCode,
2253 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2254 but as registers instead (AOP_REG) using the fReturnIdx array,
2255 * (pic16_freeAsmop): remove the freed register from the
2256 _G.sregsAlloc field,
2257 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2258 a compare of 'WREG',
2259 * (pic16_popGetTempRegCond): changed function prototype, now
2260 function takes also a bitVector argument v which holds the current
2261 set of registers that are allocated for stack access by aopForSym,
2262 registers allocated in aopForSym for accessing stack symbols are not
2263 any more part of the functions usedRegs field,
2264 * (genCall): some times aopOp is called for a stack variable to be
2265 send, aopForSym might perform the push, if this is true make sure
2266 that genCall doesn't push the variable twice by testing _G.resDirect,
2267 * (genFunction): changed testing for unspecified interrupt number
2268 from 256 to INTNO_UNSPEC,
2269 * modified selection scheme of frame pointer generation. Previously
2270 if function did use local registers a frame pointer was generated,
2271 now a frame pointer is generated only if function has arguments
2272 (that need PLUSW2 register access), or has stack arguments, or the
2273 compiler is not instructed to omit the frame pointer,
2274 * (genEndFunction): before restoring local registers that were saved
2275 in the function preamble, also restore the registers that *might*
2276 have been allocated for stack access,
2277 * (genRet): removed some old comments,
2278 * (genCmp, the active (RN's) version): added a call to the
2279 pic16_genCmp_special function to perform the compare with a more
2280 robust and optimized way,
2281 * (genInline): a feature has been added in inline code generation,
2282 which allows a wildcard variable substitution when writing inline
2283 assembly. Code is incomplete and experimental therefore undocumented,
2284 * (genCast): changed order of aopOp for result and right to allow
2285 aopForSym to directly load the result if possible,
2286 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2287 perform an optimized compare on some selected special occasions,
2288 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2289 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2290 generate an IVT any more,
2291 * src/pic16/main.c (pic16_optionsTable): added command line option
2293 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2294 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2296 * src/pic16/NOTES: Raphael Neider added in list of active developers
2297 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2298 jumptable_end to prevent bug #,
2299 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2300 inCond and outCond fields,
2301 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2302 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2303 turn off register spilling,
2304 * (packRegsForOneUse): synced with other ports' versions although it
2305 is not used currently,
2306 * (pic16_packRegisters): added an optimization while reading
2307 structure bitfields, some registers may be saved (malloc code is
2308 decreased by 80 bytes)
2310 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2312 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2313 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2314 this can be optimized more?
2316 2005-03-10 Raphael Neider <rneider AT web.de>
2318 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2319 genNearPointerGet): (hopefully) fixed access to bitfields via
2320 pointers (p->bitN = x; and x = p->bitN; failed)
2322 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
2324 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

2510 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
2511 this might fix SIGSEGVs on MinGW...
2512 * src/SDCCopt.c (killDeadCode): restored original behaviour
2513 (volatile operands might get thrown away though)

2954 Adding support for replacing ljmps with sjmps in jumptables
2955 generated for switch statements. For now you need to set the
2956 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2957 Now 4 algorithms for mcs51 jumptable generation are used:
2958 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2959 addresses loaded pc-relative for up to 112 cases and stack-pushing
2960 target addresses loaded with offset from dptr for up to 256 cases.

2990 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2992 * added libc directory. The current version of LibC contains string
2993 functions, ctype functions and macros and some functions of the
2994 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2995 be extensively tested in the future. Standard disclaimer here.
2996 Library is not automatically build yet. But one can build it by
2997 invoking 'make' inside the libc directory.
2998 * added ADC library under libio. Preliminary version yet.

3007 * (genUminusFloat): fixed for pic16, ported code from mcs51,
3008 * (pic16_storeForReturn): optimized return of 0,
3009 * (genCmp): experimental code for new genCmp which uses PIC18's
3010 special compare&skip instructions. Initial tests fail some times
3011 with variables grater than 1 byte in size, so new code is disabled,
3012 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3014 * (genCast): began a fix to optimize the casting of a bit to another
3015 bit, now assigning a bitfield to another bitfield will fail, sorry,

3020 bits with offset (case PO_GPR_BIT),
3021 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
3023 * (isBankInstruction): modified to return 0 for no banking instruction,
3024 and 1 for banking instruction,
3025 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,

6038 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6040 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6041 loaded with the linker search paths (-L arguments) and the libraries
6042 to be linked with the current source (-l arguments). Changes
6043 currently will affect only the pic16 port.
6044 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6045 include path the port specific paths and port specific libraries,
6046 * gplink command now contains the $3 argument,
6047 * src/pic16/device.h,
6048 * src/pic16/device.c,: structure PIC_device is made public and
6049 renamed to PIC16_device, the same for variable Pics which is renamed

6064 Documenting changes from previous commits.
6065 * configure.in (version 1.56),
6066 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6067 when generating output files to configure the pic16 library,
6068 but now I've commented it out, since gputils aren't installed in the
6069 SF compile farm, so library won't compile
6071 * device/lib/Makefile.in (version 1.56): initially I've added in
6072 target 'all' the prerequestive 'model-pic16' so it compiled the
6073 pic16 library, but now I've commented it out for the same reasons
6075 * added targets 'model-pic16' and 'objects-pic16' to compile the
6077 * added target 'port-specific-objects-pic16' to handle the
6078 generated libraries and copy them into the build/ directory
6079 * added target 'clean-intermediate-pic16' to clean intermediate
6080 files into pic16 directory
6081 * in target 'installdirs' added line to create directory pic16 in
6082 the installation path
6084 * device/include/Makefile.in (version 1.11): in target 'install'
6085 added lines to copy all header files to installation path,
6086 * in target 'installdirs' added line create directory for pic16
6087 headers in the installation path

6102 * src/z80/main.c (_parseOptions): fixed the portmode= command line
6103 option so that it actually works. Made it specific to the z80, since
6104 the gbz80 doesn't have these kinds of I/O ports.
6106 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6108 * device/include/z180.h,

6137 weren't marked as being in the access bank,
6139 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6141 Added portion of GNU PIC Library under the directory
6142 device/include/pic16 and device/lib/pic16. These files
6143 contain the declarations of SFRs for the PIC18Fxx2 devices.
6144 The directory is initialized via configure from toplevel.
6146 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

6174 all over. Telling LaTeX to be less strict with word spacing
6175 to better keep the right margin. Changed some notes about
6176 maintainance of the ports in section 3.2.1 - is it OK like this?
6178 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

6216 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
6218 * src/pic16/peeph.def: all peepholes with movff are commented out,
6219 because there is a problem in the pcode peep optimizer,
6220 * src/pic16/ralloc.c: the register allocator can now reuse local

6257 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6260 * src/z80/main.c: added missed needLinkerScript flags (more than
6261 one port structure defined in these file)
6262 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

6285 directive when no overlay data exist
6286 * (picglue): modified to emit uninitialized data segment
6287 according to udata_section_name

6292 arguments via -W option
6293 * src/pic16/main.c: added $l in _asmCmd, changed extension for
6294 object file from '.rel' to '.o' in port->linker structure,

6297 2004-01-07 Borut Razem <borut.razem AT siol.net>
6299 * support/scripts/sdcc.nsi: update PATH
6300 * support/scripts/sdcc.ico: craeted

6313 include information about variables allocated to the overlay
6316 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6318 * as/mcs51/lkmain.c: Help about -Y option

6330 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6332 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6333 (default behaviour).
6335 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6337 A python script to validate compiler diagnostic messages. It can be
6338 used to verify that sdcc complains about bad c source code and
6339 gives a good location of the error.
6340 * support/valdiag/Makefile,
6341 * support/valdiag/valdiag.py,
6342 * support/valdiag/tests/*
6344 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6346 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

6357 * src/common.h: added ifndef/define/endif macros
6358 around the header file.
6359 Bug reported from Jesus Calvino-Fraga
6361 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6363 * sdcc.spec: updated
6364 * device/include/Makefile.in: don't install CVS directories
6365 * device/lib/Makefile.in: added removal of CVS directories after install
6366 * doc/Makefile: fixed install, added local_icons
6367 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6368 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6369 * src/ds390/gen.c (genRightShift): fixed bug #870788
6370 * src/SDCCast.c (decorateType): fixed bug #870781
6372 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6374 PIC16 port related changes:
6375 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6376 added variable stackPos,
6378 * gen.c: genCall, assignResultValue: added support for
6379 pushing/retrieving function parameters to/from stack,
6380 genFunction,genEndFunction: setup stack frame for the
6382 genAddrOf: will be changed according to bug 863624
6384 * added files genutils.c and genutils.h which contain gen*
6385 debugged and optimised functions extracted from gen.c
6387 * glue.c: added variable 'externs' which holds extern symbols,
6388 pic16emitRegularMap: is modified to properly handle relocatable
6389 symbols under the new scheme,
6390 pic16createInterruptVect: is modified
6391 pic16printPublics: is modified to emit 'global' assembler directives,
6392 added pic16_printExterns to print extern symbols,
6393 pic16glue: initializes stack/frame pointer in the beginning of
6394 the assembly output. Temporary hack, will be corrected later,
6395 because gplink yet does not support stack and SDCC does not
6396 yet support a type of crt0.o object to create the final binary.
6398 * Removed many lines that contain 8051 legacy code.
6399 * The code is finally placed under a 'code' directive.
6400 * Added port specific options.
6402 * _process_pragma: simplified since now we do not need *special*
6403 include file to define SFR registers. But a separate header
6404 will be needed. This will be developed later.
6405 * _pic16_parseOptions: added, parses port specific options:
6406 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6407 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6408 --preplace-udata-with=
6410 * _pic16_setDefaultOptions: modified to initialize section names,
6411 but hack is temporarly out of order since it needs improvement.
6412 * _pic16_genAssemblerPreamble: configuration words are emitted by
6413 their address instead of their name. This part is incomplete and
6414 supports only the 18Fxx2 devices. Other devices will emit an error
6415 during assembly since they do not contain the same set of config
6417 * _pic16_genIVT: is modified,
6419 * pcode.c: added definitions for some hardware registers that are needed
6421 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6422 All PCI entries are updated. Now LFSR is supported.
6423 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6424 * added pic16_newpCodeOpLit2 to support instructions with
6425 two literal arguments
6426 * pic16_pCode2str: corrected code that emits assembler instructions
6427 with two literal operands and those that have an access bit modifier
6428 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6429 this fixes a bug which caused some labels to be lost, when an
6430 assembler directive was added, i.e. banksel,
6431 * pic16_FixRegisterBanking: improved logic that causes the insertion
6433 * InlineFunction: functions that are called once, are not any more
6434 inlined. This can be a port option in the future,
6436 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6438 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6439 hold the corresponding uninitialized symbols,
6440 * pic16_allocProcessorRegister: registers have explicit marked the
6442 * pic16_allocInternalRegister: registers are explicit marked as
6444 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6445 processing list, so bit registers were lost,
6448 * ralloc.h: added field 'accessBank' and original symbol operand
6449 in register definition,
6450 * removed the field isMapped from register definition,
6452 ** Several functions have been removed from various sources:
6453 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6454 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6455 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6456 pic16_assignRelocatableRegisters
6458 ** others have been introduced:
6459 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6460 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6462 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6464 * support/scripts/inc2h.pl: changed definition of BIT_AT
6465 to emit 'sbit at' instead of 'bit at'. This was a request.
6467 PIC16 port related preliminary changes:
6468 * gen.c: prefixed function popRegFromString with
6469 pic16_ and all references to it corrected
6470 * pcode.c: all pic16_pc_* hardware registers prefixed
6471 with underscore (_),
6472 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6473 * ralloc.c: newReg(): when register is REG_SFR then
6474 set address to rIdx,
6475 pic16_allocProcessorRegister(): marks register wasUsed=0
6476 pic16_writeUsedRegs(): added a call to assign processor
6477 registers via pic16_assignFixedRegisters
6479 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6481 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6482 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6483 variables in unused register banks. Also the SSEG is placed
6484 wherever there is enough space for it, and IDATA can be anywhere
6485 in internal RAM. For now compile using -Wl-Y[stack_size].
6486 The mem file is different for this option as well, since it
6487 makes no sense of talking about DSEG lenght.
6489 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6491 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6492 in certain cases, e.g. when ROM assignment, patch provided
6493 from Albert den Haan.
6495 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6638 * src/mcs51/peephole.def,
6639 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
6640 (allows non-interrupt and interrupt code to safely compete for a resource
6641 without the non-interrupt code having to disable interrupts)
6643 2003-12-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6645 * src/SDCCicode.c (geniCodeAdd),

6738 it breaks with bitfields, extern declarations, and gcse analysis.
6739 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
6740 could be assigned through a pointer, so don't complain.

7518 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7519 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7520 type for bits was changed. It resulted in bit variables becoming

7538 A few small changes that speed up the peephole optimizer.
7542 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7544 Try to make the peephole optimizer smarter by maintaining
7545 an association between the assembly source code and the
7546 iCodes that originated them. Put this information to use
7547 with a new peephole rule condition "notVolatile" so that
7548 the rules can be aggressive yet still safe.
7553 * src/mcs51/peeph.def
7555 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7559 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7560 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7561 if the left or right operand symbols have the accuse flag set.
7563 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7565 Changed the type of the result of the ! (NOT) operator to char;
7566 previously it returned the same type as the source. This allows
7567 us to eliminate all the genFloatNot functions (all of its target
7568 implementations were very buggy) since !float can use the same

7580 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7581 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7582 during interrupts. Ensure WSAVE is located at a shared bank address.
7583 2. Fixed page selection in some places
7584 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7585 the registers name strings.
7586 4. Fixed "signed / unsigned compare" compiler warnings.
7587 5. The PIC port manages its own allocation of the general purpose
7588 registers, but makes no attempt to reuse them. As a result when
7589 compiling it soon runs out of general purpose registers. Some
7590 additional code was added to the files pcode.c and device.c to walk
7591 through the function call tree and rename the registers so that they
7601 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

7608 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7610 Made bitfield a distinct type from bit so that bitfields
7611 convert as per ANSI C and bits retain their traditional
7612 boolean style behaviour. Implemented bitfield support in
7620 * src/ds390/gen.c: bit v bitfield split
7621 * src/z80/gen.c: New support for bitfields
7622 * support/regression/tests/bitfields.c: reenabled z80,
7625 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7627 Rules 246.x, 247.x relate to bitfields, the others speed up
7628 access to xdata mapped I/O devices.
7630 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7632 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7634 Cleaned up genPackBits and genUnpackBits and added two helper
7635 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7636 for literal assignments in genPackBits (thanks to Frieder for
7642 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7644 Fixed bug #748310 (pointer to function type mishandled when the
7645 function name is omitted). Also fixed a SIGSEGV when a function
7646 attribute (reentrant, etc) is used on a non-function or on a

7677 omitted, the function will not automatically be given an entry
7678 in the interrupt vector table (similar to #pragma NOIV, but

8216 from initialization assignment, since now it is a set,
8217 parseCmdLine uses setParseWithComma for linkOptions, in
8218 linkEdit() linkOptions are accessed with new function indexSet()
8219 which returns the i'th item of a set variable. See SDCCset.c, in
8220 linkEdit() when calling buildCmdLine(), added linkOptions as
8221 last argument. Now users can pass arguments to gplink via the
8222 -Wl option, main() uses pic16glue() to glue up pic16 programs

8236 gpasm complaining and test the linkage with gplink, _linkCmd and
8237 _asmCmd changed to be more gplink and gpasm friendly
8238 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8239 produced an error when parsed, peep rule 12 is added to utilize
8240 movff, but it is commented out since the pCode does not support
8241 yet a command with 2 address arguments

9263 2003-01-07 <johan AT balder>
9265 * src/SDCCast.c (decorateType): fixed bug #600035

9280 * src/SDCCicode.c: fixed array add
9282 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
9283 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
9284 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9286 2003-01-04 <johan AT balder>
9288 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9290 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9291 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9293 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9294 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

9300 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
9301 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
9303 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9304 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9306 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9308 * in \sdcc\as\mcs51\ changed these files in order to create an
9309 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9310 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9311 following files to include the previous two files: aslink.dsp,
9312 Makefile.aslink, Makefile.bcc, and Makefile.in.
9314 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9315 .adb instead of .cdb
9317 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9319 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9320 value from option --iram-size.
9322 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9324 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9327 2002-09-18 <wiml AT hhhh.org>
9329 * SDCClrange.h: exposed setFromRange() and setToRange()
9330 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9331 packRegsForAccUse() (bug 542397)
9332 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9333 multiple times and emitting the fetch operations more than once
9334 added aopGetUsesAcc() function to allow binary operators to
9335 fetch their operands in the correct order; made genMinus() emit
9336 compact code for X = LITERAL - Y
9338 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9339 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9340 sprintf() in line 1267.
9342 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9343 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9346 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9347 Changes to aslink (All the changes are marked with 'JCF'):
9349 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9352 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9353 area BSEG. Also moves, if possible, the DATA area down into the internal
9354 ram so more space is available.
9356 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9359 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9360 not bytes. Function summary() which creates a memory usage summary
9361 file with extension .mem. Reports of overlaping stack and small stack
9362 size. If the space for the stack is less than 16 bytes aslink trows a
9365 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9366 the 8051. Option 'y' for memory summary output file.
9368 Changes to sdcc (All the changes are marked with 'JCF'):
9370 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9372 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9373 overlaying area for it (uses RegBankUsed[4]).
9375 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9376 bank zero as used by default. By default aslink locates the stack
9377 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9378 the creation of the .mem file. Delegates the allocation of data area
9379 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9380 the begining of the stack area to aslink.
9382 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9383 glue() in SDCCglue.c creates an area for it.
9385 2002-09-03 Borut Razem <borut.razem AT siol.net>
9386 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9387 sdcc/src/pic/glue.c:
9388 introduced atexit() handler for teporay files removal in case of
9389 errors, assertions, ...
9391 2002-08-29 Borut Razem <borut.razem AT siol.net>
9392 * sdcc/support/cpp2/auto-host_vc_in.h:
9393 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9394 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9395 Maybe there is a similar problem with BORLANDC? It should be checked!
9397 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9398 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9399 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9400 was not executed, and the compiler (cl) launched a warning:
9401 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9403 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9404 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9406 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9407 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9409 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9410 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9411 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9412 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9413 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9414 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9415 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9416 - added Release configuration in VS projects
9417 - review of compiler an linker options
9418 - VC .exe files are generated in bin_vc directory, not to interfere
9419 with binaries generated from other projects (cygwin, mingw, bcc ...)
9421 * sdcc/src/yacc.dsp: added
9423 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9424 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9425 and insert the version number definitions from .version
9427 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9429 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9430 added - genarate auto-host.h using auto-host_vc_in.h as template
9433 removed from CVS, generated automatically
9435 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9436 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9438 2002-08-11 Borut Razem <borut.razem AT siol.net>
9439 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9441 2002-08-10 Borut Razem <borut.razem AT siol.net>
9442 * src/SDCCmain.c (main):
9443 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9444 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9445 The consequence was that some temporary files were not removed.
9448 unification of code in functions tempfilename() and tempfile():
9449 function tempnam() is defined in Visual Studio 6.0 and .NET
9451 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9453 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9454 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9455 - removed compiler command line option /WX: Treats all warnings as errors
9456 - update a list of source files, included into the project
9458 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9459 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9460 changed project type to Generic Project so that can be correcly converted to VS.NET project
9462 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9464 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9466 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9468 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9469 added return 0 statements after assert() to make compiler happy
9471 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9472 added newline in the def file to keep MSC compiler satisfied
9474 * sdcc/src/z80/gen.c:
9475 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9476 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9477 - solved MSC error in function aopDump()
9479 * sdcc_vc.h: define PREFIX as "\\sdcc"
9481 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9482 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
9484 2002-06-22 Scott Dattalo <scott AT dattalo.com>
9485 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9486 - Rewrote the register banking algorithm.
9487 - Added pCode live-range analysis to registers (for now, only non-used and
9488 singly-used registers optimized away)
9490 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9492 * 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.
9494 2002-05-10 Scott Dattalo <scott AT dattalo.com>
9495 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
9497 2002-04-22 Michael Hope <michaelh AT vroom>
9499 * device/lib/z80/printf.c: Changed emitter to volatile to work around a pcall bug.

9513 * src/z80/peeph.def: Added transpose redundent load rule.
9515 * src/z80/main.c: Added force callee saves for jaune.
9517 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
9519 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
9521 2002-03-28 Johan Knol <johan AT balder>
9523 * src/SDCCval.c: fixed bug #532436
9525 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9527 Added "char *Processor" field to the port structure.
