926 currently will affect only the pic16 port.
927 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
928 include path the port specific paths and port specific libraries,
929 * gplink command now contains the $3 argument,
930 * src/pic16/device.h,

932 renamed to PIC16_device, the same for variable Pics which is renamed
933 to Pics16. Updated all references to them.
934 * src/pic16/glue.c (pic16glue): corrected bug with code
935 initialization which bypassed the variable initializations block.
937 * device/lib/pic16/Makefile.rules: removed --penable-stack from
938 COMPILE_FLAGS and added the --nostdinc option
940 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
942 * device/include/mc68hc908jb8.h: Register defs for another member
943 of the hc08 family. Contributed by Bjorn Bringert - thanks!
945 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
947 Documenting changes from previous commits.
948 * configure.in (version 1.56),
949 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
950 when generating output files to configure the pic16 library,
951 but now I've commented it out, since gputils aren't installed in the
952 SF compile farm, so library won't compile
954 * device/lib/Makefile.in (version 1.56): initially I've added in
955 target 'all' the prerequestive 'model-pic16' so it compiled the
956 pic16 library, but now I've commented it out for the same reasons
958 * added targets 'model-pic16' and 'objects-pic16' to compile the
960 * added target 'port-specific-objects-pic16' to handle the
961 generated libraries and copy them into the build/ directory
962 * added target 'clean-intermediate-pic16' to clean intermediate
963 files into pic16 directory
964 * in target 'installdirs' added line to create directory pic16 in
965 the installation path
967 * device/include/Makefile.in (version 1.11): in target 'install'
968 added lines to copy all header files to installation path,
969 * in target 'installdirs' added line create directory for pic16
970 headers in the installation path

985 * src/z80/main.c (_parseOptions): fixed the portmode= command line
986 option so that it actually works. Made it specific to the z80, since
987 the gbz80 doesn't have these kinds of I/O ports.
989 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
991 * device/include/z180.h,

1004 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1006 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
1007 changed interrupt vector table generation to only emit declared vectors.
1008 * device/include/Makefile.in: added missing backslash
1009 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)

1013 Mainly changes to support compilation of the device libraries
1014 * src/pic16/device.c: stack is allocated via symbol and not
1015 via literal number. The symbol is placed in the corresponding
1016 position of the data ram
1017 * (pic16_dump_section): relocatable and absolute uninitialized
1018 data are now emitted in sorted order to reduce section naming,
1019 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
1020 weren't marked as being in the access bank,
1022 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
1024 Added portion of GNU PIC Library under the directory
1025 device/include/pic16 and device/lib/pic16. These files
1026 contain the declarations of SFRs for the PIC18Fxx2 devices.
1027 The directory is initialized via configure from toplevel.
1029 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
1031 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

1056 * doc/sdccman.lyx: Moved and added some sections, small changes
1057 all over. Telling LaTeX to be less strict with word spacing
1058 to better keep the right margin. Changed some notes about
1059 maintainance of the ports in section 3.2.1 - is it OK like this?
1061 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
1063 SDCC source changes:
1064 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

1098 UPPER for immediate operands,
1099 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
1101 * src/pic16/peeph.def: all peepholes with movff are commented out,
1102 because there is a problem in the pcode peep optimizer,
1103 * src/pic16/ralloc.c: the register allocator can now reuse local
1104 function symbols for another function. This saves register usage.
1105 * src/pic16/ralloc.h: added flag isLocal in structure regs,
1107 Added file src/pic16/NOTES with information about program writing on
1108 the current port version.

1140 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1143 * src/z80/main.c: added missed needLinkerScript flags (more than
1144 one port structure defined in these file)
1145 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

1161 needLinkerScript flag
1163 * src/pic16/gen.c (genAddrOf): fixed bug #863624
1164 * src/pic/glue.c: added variable udata_section_name to
1165 override default uninitialized data segment definition for
1166 devices only with SHAREBANK memory (reported from Erik Epetrich)
1167 * (pic14emitOverlay): modified to emit a commented overlay segment
1168 directive when no overlay data exist
1169 * (picglue): modified to emit uninitialized data segment
1170 according to udata_section_name

1180 2004-01-07 Borut Razem <borut.razem AT siol.net>
1182 * support/scripts/sdcc.nsi: update PATH
1183 * support/scripts/sdcc.ico: craeted

1196 include information about variables allocated to the overlay
1199 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
1201 * as/mcs51/lkmain.c: Help about -Y option

1213 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
1215 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
1216 (default behaviour).
1218 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1220 A python script to validate compiler diagnostic messages. It can be
1221 used to verify that sdcc complains about bad c source code and
1222 gives a good location of the error.
1223 * support/valdiag/Makefile,
1224 * support/valdiag/valdiag.py,
1225 * support/valdiag/tests/*
1227 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

1240 * src/common.h: added ifndef/define/endif macros
1241 around the header file.
1242 Bug reported from Jesus Calvino-Fraga
1244 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
1246 * sdcc.spec: updated
1247 * device/include/Makefile.in: don't install CVS directories
1248 * device/lib/Makefile.in: added removal of CVS directories after install
1249 * doc/Makefile: fixed install, added local_icons
1250 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
1251 * src/mcs51/gen.c (genRightShift): fixed bug #870788
1252 * src/ds390/gen.c (genRightShift): fixed bug #870788
1253 * src/SDCCast.c (decorateType): fixed bug #870781
1255 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
1257 PIC16 port related changes:
1258 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
1259 added variable stackPos,
1261 * gen.c: genCall, assignResultValue: added support for
1262 pushing/retrieving function parameters to/from stack,
1263 genFunction,genEndFunction: setup stack frame for the
1265 genAddrOf: will be changed according to bug 863624
1267 * added files genutils.c and genutils.h which contain gen*
1268 debugged and optimised functions extracted from gen.c
1270 * glue.c: added variable 'externs' which holds extern symbols,
1271 pic16emitRegularMap: is modified to properly handle relocatable
1272 symbols under the new scheme,
1273 pic16createInterruptVect: is modified
1274 pic16printPublics: is modified to emit 'global' assembler directives,
1275 added pic16_printExterns to print extern symbols,
1276 pic16glue: initializes stack/frame pointer in the beginning of
1277 the assembly output. Temporary hack, will be corrected later,
1278 because gplink yet does not support stack and SDCC does not
1279 yet support a type of crt0.o object to create the final binary.
1281 * Removed many lines that contain 8051 legacy code.
1282 * The code is finally placed under a 'code' directive.
1283 * Added port specific options.
1285 * _process_pragma: simplified since now we do not need *special*
1286 include file to define SFR registers. But a separate header
1287 will be needed. This will be developed later.
1288 * _pic16_parseOptions: added, parses port specific options:
1289 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
1290 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
1291 --preplace-udata-with=
1293 * _pic16_setDefaultOptions: modified to initialize section names,
1294 but hack is temporarly out of order since it needs improvement.
1295 * _pic16_genAssemblerPreamble: configuration words are emitted by
1296 their address instead of their name. This part is incomplete and
1297 supports only the 18Fxx2 devices. Other devices will emit an error
1298 during assembly since they do not contain the same set of config
1300 * _pic16_genIVT: is modified,
1302 * pcode.c: added definitions for some hardware registers that are needed
1304 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
1305 All PCI entries are updated. Now LFSR is supported.
1306 * Removed pic16_pciTRIS is mentioned by mdubuc in source
1307 * added pic16_newpCodeOpLit2 to support instructions with
1308 two literal arguments
1309 * pic16_pCode2str: corrected code that emits assembler instructions
1310 with two literal operands and those that have an access bit modifier
1311 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
1312 this fixes a bug which caused some labels to be lost, when an
1313 assembler directive was added, i.e. banksel,
1314 * pic16_FixRegisterBanking: improved logic that causes the insertion
1316 * InlineFunction: functions that are called once, are not any more
1317 inlined. This can be a port option in the future,
1319 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
1321 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
1322 hold the corresponding uninitialized symbols,
1323 * pic16_allocProcessorRegister: registers have explicit marked the
1325 * pic16_allocInternalRegister: registers are explicit marked as
1327 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
1328 processing list, so bit registers were lost,
1331 * ralloc.h: added field 'accessBank' and original symbol operand
1332 in register definition,
1333 * removed the field isMapped from register definition,
1335 ** Several functions have been removed from various sources:
1336 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
1337 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
1338 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
1339 pic16_assignRelocatableRegisters
1341 ** others have been introduced:
1342 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
1343 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
1345 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
1347 * support/scripts/inc2h.pl: changed definition of BIT_AT
1348 to emit 'sbit at' instead of 'bit at'. This was a request.
1350 PIC16 port related preliminary changes:
1351 * gen.c: prefixed function popRegFromString with
1352 pic16_ and all references to it corrected
1353 * pcode.c: all pic16_pc_* hardware registers prefixed
1354 with underscore (_),
1355 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
1356 * ralloc.c: newReg(): when register is REG_SFR then
1357 set address to rIdx,
1358 pic16_allocProcessorRegister(): marks register wasUsed=0
1359 pic16_writeUsedRegs(): added a call to assign processor
1360 registers via pic16_assignFixedRegisters
1362 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
1364 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
1365 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
1366 variables in unused register banks. Also the SSEG is placed
1367 wherever there is enough space for it, and IDATA can be anywhere
1368 in internal RAM. For now compile using -Wl-Y[stack_size].
1369 The mem file is different for this option as well, since it
1370 makes no sense of talking about DSEG lenght.
1372 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
1374 * src/SDCClrange.c: fixed bug 869095 that caused segfault
1375 in certain cases, e.g. when ROM assignment, patch provided
1376 from Albert den Haan.
1378 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

2421 A few small changes that speed up the peephole optimizer.
2425 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2427 Try to make the peephole optimizer smarter by maintaining
2428 an association between the assembly source code and the
2429 iCodes that originated them. Put this information to use
2430 with a new peephole rule condition "notVolatile" so that
2431 the rules can be aggressive yet still safe.
2436 * src/mcs51/peeph.def
2438 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2442 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
2443 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
2444 if the left or right operand symbols have the accuse flag set.
2446 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2448 Changed the type of the result of the ! (NOT) operator to char;
2449 previously it returned the same type as the source. This allows
2450 us to eliminate all the genFloatNot functions (all of its target
2451 implementations were very buggy) since !float can use the same
2454 * src/SDCCicode.c (ast2iCode): ! returns char
2455 * src/mcs51/gen.c (genNot, genNotFloat),
2456 * src/ds390/gen.c (genNot, genNotFloat),
2457 * src/z80/gen.c (genNot, genNotFloat),
2458 * src/pic/gen.c (genNot, genNotFloat),
2459 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

2463 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
2464 1. Interrupt would not compile properly. Ensure PCLATH register is saved
2465 during interrupts. Ensure WSAVE is located at a shared bank address.
2466 2. Fixed page selection in some places
2467 3. Fixed BTFSS/C to where necessary use registers directly and not simply
2468 the registers name strings.
2469 4. Fixed "signed / unsigned compare" compiler warnings.
2470 5. The PIC port manages its own allocation of the general purpose
2471 registers, but makes no attempt to reuse them. As a result when
2472 compiling it soon runs out of general purpose registers. Some
2473 additional code was added to the files pcode.c and device.c to walk
2474 through the function call tree and rename the registers so that they
2484 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
2485 genPlus() & genMinus() when the result is the same as left or right

2491 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2493 Made bitfield a distinct type from bit so that bitfields
2494 convert as per ANSI C and bits retain their traditional
2495 boolean style behaviour. Implemented bitfield support in
2503 * src/ds390/gen.c: bit v bitfield split
2504 * src/z80/gen.c: New support for bitfields
2505 * support/regression/tests/bitfields.c: reenabled z80,
2508 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
2510 Rules 246.x, 247.x relate to bitfields, the others speed up
2511 access to xdata mapped I/O devices.
2513 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
2515 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2517 Cleaned up genPackBits and genUnpackBits and added two helper
2518 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
2519 for literal assignments in genPackBits (thanks to Frieder for
2525 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2527 Fixed bug #748310 (pointer to function type mishandled when the
2528 function name is omitted). Also fixed a SIGSEGV when a function
2529 attribute (reentrant, etc) is used on a non-function or on a
2530 function but misplaced before the parameter list.
2532 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
2534 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

2557 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2559 Made the constant following the "interrupt" keyword optional. If
2560 omitted, the function will not automatically be given an entry
2561 in the interrupt vector table (similar to #pragma NOIV, but
2562 less syntacticly kludgy). The interrupt number is also now
2563 range checked. Also fixed a bug in the high order bit example

2579 * src/SDCCsymt.c (computeType): literals are handled the same way as any
2581 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
2582 be re-activated by defining REDUCE_LITERALS)

2584 unsigned, but are signed by default
2585 * src/SDCCval.c (constVal): rearranged
2586 * src/SDCCval.c (valMod): preliminary fix
2587 * src/SDCCval.c (valCastLiteral): use TYPE_* types

3032 * src/avr/avr.dsp, src/ds390/ds390.dsp, src/mcs51/mcs51.dsp,
3033 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
3034 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used
3037 2003-05-25 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3039 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
3040 the regression tests I'm not brave enough to enable 245.b, 245.c
3041 * doc/sdccman.lyx: added latex preamble for hyperref package.
3042 Using pdflatex this will give you a hyperlinked pdf file with
3043 bookmarks. (prepend '%' before /usepackage if this breaks something)

3055 * src/SDCCglue.c (printIval): fixed bug #739934
3057 2003-05-19 Bernhard Held <bernhard AT bernhardheld.de>
3059 Applied patch from bug 737905 (renamed yylineo to mylineno):
3066 * src/pic16/pcode.c: Cleaned warnings
3067 * src/pic16/pcodeflow.c: Cleaned warnings
3068 * src/pic16/pcoderegs.c: Cleaned warnings

3081 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
3083 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
3084 it can be defined with CFLAGS when running configure
3085 * src/SDCCmain.c: fixed compiling + linking with object files
3087 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
3089 * configure.in: configure for pic16 port,
3090 added --disable-pic16-port
3091 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
3092 * src/SDCCmain.c: linkOptions is changed to set *,
3093 added if/endif conditional macros to remove options help
3094 messages from optionsTable when a port is not configured, added
3095 support for the PIc16 port in the ports table, when executing
3096 the compiler with no port specified on command line, a default
3097 port is selected with the new macro DEFAULT_PORT which is
3098 defined in port.h, in setDefaultOptions() linkOptions is removed
3099 from initialization assignment, since now it is a set,
3100 parseCmdLine uses setParseWithComma for linkOptions, in
3101 linkEdit() linkOptions are accessed with new function indexSet()
3102 which returns the i'th item of a set variable. See SDCCset.c, in
3103 linkEdit() when calling buildCmdLine(), added linkOptions as
3104 last argument. Now users can pass arguments to gplink via the
3105 -Wl option, main() uses pic16glue() to glue up pic16 programs
3106 * src/SDCCpeeph.c: various changes to support pic16
3107 * src/SDCCset.c: added function void *indexSet(set *, int) to

3115 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
3117 * src/pic16/glue.c: commented out some error producing lines
3118 * src/pic16/main.c: __config directives are commented out to stop
3119 gpasm complaining and test the linkage with gplink, _linkCmd and
3120 _asmCmd changed to be more gplink and gpasm friendly
3121 * src/pic16/peeph.def: peep rule 3 is commented out, since it
3122 produced an error when parsed, peep rule 12 is added to utilize
3123 movff, but it is commented out since the pCode does not support
3124 yet a command with 2 address arguments
3126 2003-05-18 <johan AT balder>
3128 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
3129 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT
3130 2003-05-17 Karl Bongers(apply patches from Martin Helmling)

3153 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
3155 2003-05-11 Borut Razem <borut.razem AT siol.net>
3157 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
3158 the path of bin directory, so that PATH is the only env. variable, which has to be set
3159 in case of standard installation.
3160 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

4163 * src/SDCCicode.c: fixed array add
4165 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
4166 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
4167 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
4169 2003-01-04 <johan AT balder>
4171 * src/SDCCval.c (getNelements): fixed the initialized array of structures
4173 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4174 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
4176 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
4177 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

4186 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
4187 * src/mcs51/main.c: removed {bindir}{sep} from aslink
4189 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4191 * in \sdcc\as\mcs51\ changed these files in order to create an
4192 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
4193 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
4194 following files to include the previous two files: aslink.dsp,
4195 Makefile.aslink, Makefile.bcc, and Makefile.in.
4197 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
4198 .adb instead of .cdb
4200 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4202 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
4203 value from option --iram-size.
4205 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4207 * \sdcc\as\mcs51\lklist.c: added boundary check before using
4210 2002-09-18 <wiml AT hhhh.org>
4212 * SDCClrange.h: exposed setFromRange() and setToRange()
4213 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
4214 packRegsForAccUse() (bug 542397)
4215 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
4216 multiple times and emitting the fetch operations more than once
4217 added aopGetUsesAcc() function to allow binary operators to
4218 fetch their operands in the correct order; made genMinus() emit
4219 compact code for X = LITERAL - Y
4221 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4222 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
4223 sprintf() in line 1267.
4225 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4226 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
4229 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4230 Changes to aslink (All the changes are marked with 'JCF'):
4232 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
4235 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
4236 area BSEG. Also moves, if possible, the DATA area down into the internal
4237 ram so more space is available.
4239 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
4242 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
4243 not bytes. Function summary() which creates a memory usage summary
4244 file with extension .mem. Reports of overlaping stack and small stack
4245 size. If the space for the stack is less than 16 bytes aslink trows a
4248 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
4249 the 8051. Option 'y' for memory summary output file.
4251 Changes to sdcc (All the changes are marked with 'JCF'):
4253 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
4255 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
4256 overlaying area for it (uses RegBankUsed[4]).
4258 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
4259 bank zero as used by default. By default aslink locates the stack
4260 (equivalent to --stack-after-data). Pass option 'y' to aslink for
4261 the creation of the .mem file. Delegates the allocation of data area
4262 to aslink (it is not longer 0x30 by default). If --stack-loc passes
4263 the begining of the stack area to aslink.
4265 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
4266 glue() in SDCCglue.c creates an area for it.
4268 2002-09-03 Borut Razem <borut.razem AT siol.net>
4269 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
4270 sdcc/src/pic/glue.c:
4271 introduced atexit() handler for teporay files removal in case of
4272 errors, assertions, ...
4274 2002-08-29 Borut Razem <borut.razem AT siol.net>
4275 * sdcc/support/cpp2/auto-host_vc_in.h:
4276 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
4277 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
4278 Maybe there is a similar problem with BORLANDC? It should be checked!
4280 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
4281 corrected improper use of assert: the assignment to clr variable was done inside the assert.
4282 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
4283 was not executed, and the compiler (cl) launched a warning:
4284 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
4286 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
4287 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
4289 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
4290 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
4292 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
4293 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
4294 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
4295 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
4296 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
4297 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
4298 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
4299 - added Release configuration in VS projects
4300 - review of compiler an linker options
4301 - VC .exe files are generated in bin_vc directory, not to interfere
4302 with binaries generated from other projects (cygwin, mingw, bcc ...)
4304 * sdcc/src/yacc.dsp: added
4306 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
4307 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
4308 and insert the version number definitions from .version
4310 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
4312 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
4313 added - genarate auto-host.h using auto-host_vc_in.h as template
4316 removed from CVS, generated automatically
4318 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
4319 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
4321 2002-08-11 Borut Razem <borut.razem AT siol.net>
4322 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
4324 2002-08-10 Borut Razem <borut.razem AT siol.net>
4325 * src/SDCCmain.c (main):
4326 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
4327 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
4328 The consequence was that some temporary files were not removed.
4331 unification of code in functions tempfilename() and tempfile():
4332 function tempnam() is defined in Visual Studio 6.0 and .NET
4334 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
4336 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
4337 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
4338 - removed compiler command line option /WX: Treats all warnings as errors
4339 - update a list of source files, included into the project
4341 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,

4352 added return 0 statements after assert() to make compiler happy
4354 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
4355 added newline in the def file to keep MSC compiler satisfied
4357 * sdcc/src/z80/gen.c:
4358 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
4359 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
4360 - solved MSC error in function aopDump()
4362 * sdcc_vc.h: define PREFIX as "\\sdcc"

4539 * sdcc/src/SDCCloop.c:
4540 Previous fix was not good. basic blocks that have "break" or "return" are
4541 not really partof a loop , but live ranges used in these blocks should
4542 be live thru the entire loop, so set partOfLoop but don't add them to
