933 currently will affect only the pic16 port.
934 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
935 include path the port specific paths and port specific libraries,
936 * gplink command now contains the $3 argument,
937 * src/pic16/device.h,
938 * src/pic16/device.c,: structure PIC_device is made public and
939 renamed to PIC16_device, the same for variable Pics which is renamed
940 to Pics16. Updated all references to them.
941 * src/pic16/glue.c (pic16glue): corrected bug with code
942 initialization which bypassed the variable initializations block.
944 * device/lib/pic16/Makefile.rules: removed --penable-stack from
945 COMPILE_FLAGS and added the --nostdinc option
947 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
949 * device/include/mc68hc908jb8.h: Register defs for another member
950 of the hc08 family. Contributed by Bjorn Bringert - thanks!
952 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
954 Documenting changes from previous commits.
955 * configure.in (version 1.56),
956 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
957 when generating output files to configure the pic16 library,
958 but now I've commented it out, since gputils aren't installed in the
959 SF compile farm, so library won't compile
961 * device/lib/Makefile.in (version 1.56): initially I've added in
962 target 'all' the prerequestive 'model-pic16' so it compiled the
963 pic16 library, but now I've commented it out for the same reasons
965 * added targets 'model-pic16' and 'objects-pic16' to compile the
967 * added target 'port-specific-objects-pic16' to handle the
968 generated libraries and copy them into the build/ directory
969 * added target 'clean-intermediate-pic16' to clean intermediate
970 files into pic16 directory
971 * in target 'installdirs' added line to create directory pic16 in
972 the installation path
974 * device/include/Makefile.in (version 1.11): in target 'install'
975 added lines to copy all header files to installation path,
976 * in target 'installdirs' added line create directory for pic16
977 headers in the installation path

992 * src/z80/main.c (_parseOptions): fixed the portmode= command line
993 option so that it actually works. Made it specific to the z80, since
994 the gbz80 doesn't have these kinds of I/O ports.
996 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
998 * device/include/z180.h,

1020 Mainly changes to support compilation of the device libraries
1021 * src/pic16/device.c: stack is allocated via symbol and not
1022 via literal number. The symbol is placed in the corresponding
1023 position of the data ram
1024 * (pic16_dump_section): relocatable and absolute uninitialized
1025 data are now emitted in sorted order to reduce section naming,
1026 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
1027 weren't marked as being in the access bank,
1029 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
1031 Added portion of GNU PIC Library under the directory
1032 device/include/pic16 and device/lib/pic16. These files
1033 contain the declarations of SFRs for the PIC18Fxx2 devices.
1034 The directory is initialized via configure from toplevel.
1036 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
1038 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
1039 the spilllocations to be compared correctly
1041 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
1043 * src/SDCCast.c (decorateType): fixed bug introduced today
1045 2004-01-12 Borut Razem <borut.razem AT siol.net>

1063 * doc/sdccman.lyx: Moved and added some sections, small changes
1064 all over. Telling LaTeX to be less strict with word spacing
1065 to better keep the right margin. Changed some notes about
1066 maintainance of the ports in section 3.2.1 - is it OK like this?
1068 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

1105 UPPER for immediate operands,
1106 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
1108 * src/pic16/peeph.def: all peepholes with movff are commented out,
1109 because there is a problem in the pcode peep optimizer,
1110 * src/pic16/ralloc.c: the register allocator can now reuse local
1111 function symbols for another function. This saves register usage.
1112 * src/pic16/ralloc.h: added flag isLocal in structure regs,
1114 Added file src/pic16/NOTES with information about program writing on
1115 the current port version.

1147 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1150 * src/z80/main.c: added missed needLinkerScript flags (more than
1151 one port structure defined in these file)
1152 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

1168 needLinkerScript flag
1170 * src/pic16/gen.c (genAddrOf): fixed bug #863624
1171 * src/pic/glue.c: added variable udata_section_name to
1172 override default uninitialized data segment definition for
1173 devices only with SHAREBANK memory (reported from Erik Epetrich)
1174 * (pic14emitOverlay): modified to emit a commented overlay segment
1175 directive when no overlay data exist
1176 * (picglue): modified to emit uninitialized data segment
1177 according to udata_section_name

1187 2004-01-07 Borut Razem <borut.razem AT siol.net>
1189 * support/scripts/sdcc.nsi: update PATH
1190 * support/scripts/sdcc.ico: craeted

1203 include information about variables allocated to the overlay
1206 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
1208 * as/mcs51/lkmain.c: Help about -Y option

1220 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
1222 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
1223 (default behaviour).
1225 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1227 A python script to validate compiler diagnostic messages. It can be
1228 used to verify that sdcc complains about bad c source code and
1229 gives a good location of the error.
1230 * support/valdiag/Makefile,
1231 * support/valdiag/valdiag.py,
1232 * support/valdiag/tests/*
1234 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

1247 * src/common.h: added ifndef/define/endif macros
1248 around the header file.
1249 Bug reported from Jesus Calvino-Fraga
1251 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
1253 * sdcc.spec: updated
1254 * device/include/Makefile.in: don't install CVS directories
1255 * device/lib/Makefile.in: added removal of CVS directories after install
1256 * doc/Makefile: fixed install, added local_icons
1257 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
1258 * src/mcs51/gen.c (genRightShift): fixed bug #870788
1259 * src/ds390/gen.c (genRightShift): fixed bug #870788
1260 * src/SDCCast.c (decorateType): fixed bug #870781
1262 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
1264 PIC16 port related changes:
1265 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
1266 added variable stackPos,
1268 * gen.c: genCall, assignResultValue: added support for
1269 pushing/retrieving function parameters to/from stack,
1270 genFunction,genEndFunction: setup stack frame for the
1272 genAddrOf: will be changed according to bug 863624
1274 * added files genutils.c and genutils.h which contain gen*
1275 debugged and optimised functions extracted from gen.c
1277 * glue.c: added variable 'externs' which holds extern symbols,
1278 pic16emitRegularMap: is modified to properly handle relocatable
1279 symbols under the new scheme,
1280 pic16createInterruptVect: is modified
1281 pic16printPublics: is modified to emit 'global' assembler directives,
1282 added pic16_printExterns to print extern symbols,
1283 pic16glue: initializes stack/frame pointer in the beginning of
1284 the assembly output. Temporary hack, will be corrected later,
1285 because gplink yet does not support stack and SDCC does not
1286 yet support a type of crt0.o object to create the final binary.
1288 * Removed many lines that contain 8051 legacy code.
1289 * The code is finally placed under a 'code' directive.
1290 * Added port specific options.
1292 * _process_pragma: simplified since now we do not need *special*
1293 include file to define SFR registers. But a separate header
1294 will be needed. This will be developed later.
1295 * _pic16_parseOptions: added, parses port specific options:
1296 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
1297 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
1298 --preplace-udata-with=
1300 * _pic16_setDefaultOptions: modified to initialize section names,
1301 but hack is temporarly out of order since it needs improvement.
1302 * _pic16_genAssemblerPreamble: configuration words are emitted by
1303 their address instead of their name. This part is incomplete and
1304 supports only the 18Fxx2 devices. Other devices will emit an error
1305 during assembly since they do not contain the same set of config
1307 * _pic16_genIVT: is modified,
1309 * pcode.c: added definitions for some hardware registers that are needed
1311 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
1312 All PCI entries are updated. Now LFSR is supported.
1313 * Removed pic16_pciTRIS is mentioned by mdubuc in source
1314 * added pic16_newpCodeOpLit2 to support instructions with
1315 two literal arguments
1316 * pic16_pCode2str: corrected code that emits assembler instructions
1317 with two literal operands and those that have an access bit modifier
1318 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
1319 this fixes a bug which caused some labels to be lost, when an
1320 assembler directive was added, i.e. banksel,
1321 * pic16_FixRegisterBanking: improved logic that causes the insertion
1323 * InlineFunction: functions that are called once, are not any more
1324 inlined. This can be a port option in the future,
1326 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
1328 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
1329 hold the corresponding uninitialized symbols,
1330 * pic16_allocProcessorRegister: registers have explicit marked the
1332 * pic16_allocInternalRegister: registers are explicit marked as
1334 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
1335 processing list, so bit registers were lost,
1338 * ralloc.h: added field 'accessBank' and original symbol operand
1339 in register definition,
1340 * removed the field isMapped from register definition,
1342 ** Several functions have been removed from various sources:
1343 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
1344 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
1345 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
1346 pic16_assignRelocatableRegisters
1348 ** others have been introduced:
1349 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
1350 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
1352 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
1354 * support/scripts/inc2h.pl: changed definition of BIT_AT
1355 to emit 'sbit at' instead of 'bit at'. This was a request.
1357 PIC16 port related preliminary changes:
1358 * gen.c: prefixed function popRegFromString with
1359 pic16_ and all references to it corrected
1360 * pcode.c: all pic16_pc_* hardware registers prefixed
1361 with underscore (_),
1362 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
1363 * ralloc.c: newReg(): when register is REG_SFR then
1364 set address to rIdx,
1365 pic16_allocProcessorRegister(): marks register wasUsed=0
1366 pic16_writeUsedRegs(): added a call to assign processor
1367 registers via pic16_assignFixedRegisters
1369 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
1371 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
1372 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
1373 variables in unused register banks. Also the SSEG is placed
1374 wherever there is enough space for it, and IDATA can be anywhere
1375 in internal RAM. For now compile using -Wl-Y[stack_size].
1376 The mem file is different for this option as well, since it
1377 makes no sense of talking about DSEG lenght.
1379 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
1381 * src/SDCClrange.c: fixed bug 869095 that caused segfault
1382 in certain cases, e.g. when ROM assignment, patch provided
1383 from Albert den Haan.
1385 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

2428 A few small changes that speed up the peephole optimizer.
2432 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2434 Try to make the peephole optimizer smarter by maintaining
2435 an association between the assembly source code and the
2436 iCodes that originated them. Put this information to use
2437 with a new peephole rule condition "notVolatile" so that
2438 the rules can be aggressive yet still safe.
2443 * src/mcs51/peeph.def
2445 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2449 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
2450 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
2451 if the left or right operand symbols have the accuse flag set.
2453 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2455 Changed the type of the result of the ! (NOT) operator to char;
2456 previously it returned the same type as the source. This allows
2457 us to eliminate all the genFloatNot functions (all of its target
2458 implementations were very buggy) since !float can use the same
2461 * src/SDCCicode.c (ast2iCode): ! returns char
2462 * src/mcs51/gen.c (genNot, genNotFloat),
2463 * src/ds390/gen.c (genNot, genNotFloat),
2464 * src/z80/gen.c (genNot, genNotFloat),
2465 * src/pic/gen.c (genNot, genNotFloat),
2466 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

2470 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
2471 1. Interrupt would not compile properly. Ensure PCLATH register is saved
2472 during interrupts. Ensure WSAVE is located at a shared bank address.
2473 2. Fixed page selection in some places
2474 3. Fixed BTFSS/C to where necessary use registers directly and not simply
2475 the registers name strings.
2476 4. Fixed "signed / unsigned compare" compiler warnings.
2477 5. The PIC port manages its own allocation of the general purpose
2478 registers, but makes no attempt to reuse them. As a result when
2479 compiling it soon runs out of general purpose registers. Some
2480 additional code was added to the files pcode.c and device.c to walk
2481 through the function call tree and rename the registers so that they
2491 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
2492 genPlus() & genMinus() when the result is the same as left or right
2494 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

2498 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2500 Made bitfield a distinct type from bit so that bitfields
2501 convert as per ANSI C and bits retain their traditional
2502 boolean style behaviour. Implemented bitfield support in
2510 * src/ds390/gen.c: bit v bitfield split
2511 * src/z80/gen.c: New support for bitfields
2512 * support/regression/tests/bitfields.c: reenabled z80,
2515 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
2517 Rules 246.x, 247.x relate to bitfields, the others speed up
2518 access to xdata mapped I/O devices.
2520 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
2522 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2524 Cleaned up genPackBits and genUnpackBits and added two helper
2525 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
2526 for literal assignments in genPackBits (thanks to Frieder for
2532 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2534 Fixed bug #748310 (pointer to function type mishandled when the
2535 function name is omitted). Also fixed a SIGSEGV when a function
2536 attribute (reentrant, etc) is used on a non-function or on a
2537 function but misplaced before the parameter list.
2539 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
2541 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

2564 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2566 Made the constant following the "interrupt" keyword optional. If
2567 omitted, the function will not automatically be given an entry
2568 in the interrupt vector table (similar to #pragma NOIV, but
2569 less syntacticly kludgy). The interrupt number is also now
2570 range checked. Also fixed a bug in the high order bit example

2591 unsigned, but are signed by default
2592 * src/SDCCval.c (constVal): rearranged
2593 * src/SDCCval.c (valMod): preliminary fix
2594 * src/SDCCval.c (valCastLiteral): use TYPE_* types

3017 for a non-native english speaker.
3018 Please feel free to add to the manual or to correct my changes.

3031 * device/lib/gbz80/stubs.s
3032 * device/lib/z80/mul.s
3033 * device/lib/z80/stubs.s

3036 2003-05-25 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3038 * as/mcs51/lkaomf51.c: Address space 'z' was missing.
3039 * src/avr/avr.dsp, src/ds390/ds390.dsp, src/mcs51/mcs51.dsp,
3040 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
3041 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used
3044 2003-05-25 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3046 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
3047 the regression tests I'm not brave enough to enable 245.b, 245.c
3048 * doc/sdccman.lyx: added latex preamble for hyperref package.
3049 Using pdflatex this will give you a hyperlinked pdf file with
3050 bookmarks. (prepend '%' before /usepackage if this breaks something)
3052 2003-05-24 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

3062 * src/SDCCglue.c (printIval): fixed bug #739934
3064 2003-05-19 Bernhard Held <bernhard AT bernhardheld.de>
3066 Applied patch from bug 737905 (renamed yylineo to mylineno):
3073 * src/pic16/pcode.c: Cleaned warnings
3074 * src/pic16/pcodeflow.c: Cleaned warnings
3075 * src/pic16/pcoderegs.c: Cleaned warnings

3088 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
3090 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
3091 it can be defined with CFLAGS when running configure
3092 * src/SDCCmain.c: fixed compiling + linking with object files
3094 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
3096 * configure.in: configure for pic16 port,
3097 added --disable-pic16-port
3098 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
3099 * src/SDCCmain.c: linkOptions is changed to set *,
3100 added if/endif conditional macros to remove options help
3101 messages from optionsTable when a port is not configured, added
3102 support for the PIc16 port in the ports table, when executing
3103 the compiler with no port specified on command line, a default
3104 port is selected with the new macro DEFAULT_PORT which is
3105 defined in port.h, in setDefaultOptions() linkOptions is removed
3106 from initialization assignment, since now it is a set,
3107 parseCmdLine uses setParseWithComma for linkOptions, in
3108 linkEdit() linkOptions are accessed with new function indexSet()
3109 which returns the i'th item of a set variable. See SDCCset.c, in
3110 linkEdit() when calling buildCmdLine(), added linkOptions as
3111 last argument. Now users can pass arguments to gplink via the
3112 -Wl option, main() uses pic16glue() to glue up pic16 programs
3113 * src/SDCCpeeph.c: various changes to support pic16
3114 * src/SDCCset.c: added function void *indexSet(set *, int) to

3122 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
3124 * src/pic16/glue.c: commented out some error producing lines
3125 * src/pic16/main.c: __config directives are commented out to stop
3126 gpasm complaining and test the linkage with gplink, _linkCmd and
3127 _asmCmd changed to be more gplink and gpasm friendly
3128 * src/pic16/peeph.def: peep rule 3 is commented out, since it
3129 produced an error when parsed, peep rule 12 is added to utilize
3130 movff, but it is commented out since the pCode does not support
3131 yet a command with 2 address arguments
3133 2003-05-18 <johan AT balder>
3135 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
3136 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT
3137 2003-05-17 Karl Bongers(apply patches from Martin Helmling)

3160 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
3162 2003-05-11 Borut Razem <borut.razem AT siol.net>
3164 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
3165 the path of bin directory, so that PATH is the only env. variable, which has to be set
3166 in case of standard installation.
3167 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

4196 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4198 * in \sdcc\as\mcs51\ changed these files in order to create an
4199 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
4200 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
4201 following files to include the previous two files: aslink.dsp,
4202 Makefile.aslink, Makefile.bcc, and Makefile.in.
4204 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
4205 .adb instead of .cdb
4207 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4209 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
4210 value from option --iram-size.
4212 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4214 * \sdcc\as\mcs51\lklist.c: added boundary check before using
4217 2002-09-18 <wiml AT hhhh.org>
4219 * SDCClrange.h: exposed setFromRange() and setToRange()
4220 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
4221 packRegsForAccUse() (bug 542397)
4222 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
4223 multiple times and emitting the fetch operations more than once
4224 added aopGetUsesAcc() function to allow binary operators to
4225 fetch their operands in the correct order; made genMinus() emit
4226 compact code for X = LITERAL - Y
4228 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4229 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
4230 sprintf() in line 1267.
4232 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4233 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
4236 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4237 Changes to aslink (All the changes are marked with 'JCF'):
4239 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
4242 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
4243 area BSEG. Also moves, if possible, the DATA area down into the internal
4244 ram so more space is available.
4246 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
4249 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
4250 not bytes. Function summary() which creates a memory usage summary
4251 file with extension .mem. Reports of overlaping stack and small stack
4252 size. If the space for the stack is less than 16 bytes aslink trows a
4255 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
4256 the 8051. Option 'y' for memory summary output file.
4258 Changes to sdcc (All the changes are marked with 'JCF'):
4260 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
4262 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
4263 overlaying area for it (uses RegBankUsed[4]).
4265 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
4266 bank zero as used by default. By default aslink locates the stack
4267 (equivalent to --stack-after-data). Pass option 'y' to aslink for
4268 the creation of the .mem file. Delegates the allocation of data area
4269 to aslink (it is not longer 0x30 by default). If --stack-loc passes
4270 the begining of the stack area to aslink.
4272 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
4273 glue() in SDCCglue.c creates an area for it.
4275 2002-09-03 Borut Razem <borut.razem AT siol.net>
4276 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
4277 sdcc/src/pic/glue.c:
4278 introduced atexit() handler for teporay files removal in case of
4279 errors, assertions, ...
4281 2002-08-29 Borut Razem <borut.razem AT siol.net>
4282 * sdcc/support/cpp2/auto-host_vc_in.h:
4283 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
4284 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
4285 Maybe there is a similar problem with BORLANDC? It should be checked!
4287 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
4288 corrected improper use of assert: the assignment to clr variable was done inside the assert.
4289 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
4290 was not executed, and the compiler (cl) launched a warning:
4291 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
4293 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>

4306 - added Release configuration in VS projects
4307 - review of compiler an linker options
4308 - VC .exe files are generated in bin_vc directory, not to interfere
4309 with binaries generated from other projects (cygwin, mingw, bcc ...)
4311 * sdcc/src/yacc.dsp: added
4313 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
4314 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
4315 and insert the version number definitions from .version
4317 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
4319 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

4323 removed from CVS, generated automatically
4325 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
4326 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
4328 2002-08-11 Borut Razem <borut.razem AT siol.net>
4329 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
4331 2002-08-10 Borut Razem <borut.razem AT siol.net>
4332 * src/SDCCmain.c (main):
4333 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
4334 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
4335 The consequence was that some temporary files were not removed.
4338 unification of code in functions tempfilename() and tempfile():
4339 function tempnam() is defined in Visual Studio 6.0 and .NET
4341 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
4343 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
4344 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
4345 - removed compiler command line option /WX: Treats all warnings as errors
4346 - update a list of source files, included into the project
4348 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
4349 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
4350 changed project type to Generic Project so that can be correcly converted to VS.NET project
4352 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
4354 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

4358 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
4359 added return 0 statements after assert() to make compiler happy
4361 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
4362 added newline in the def file to keep MSC compiler satisfied
4364 * sdcc/src/z80/gen.c:
4365 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
4366 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
4367 - solved MSC error in function aopDump()
4369 * sdcc_vc.h: define PREFIX as "\\sdcc"
4371 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

4427 were not getting allocated.
4429 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
4432 Fixed left shift. Will promote the left side of a left shift
4433 if a) left shifting more than size of operand or b) when assigned
4434 to something size > size of left side
4436 2002-03-14 Scott Dattalo <scott AT dattalo.com>

4546 * sdcc/src/SDCCloop.c:
4547 Previous fix was not good. basic blocks that have "break" or "return" are
4548 not really partof a loop , but live ranges used in these blocks should
4549 be live thru the entire loop, so set partOfLoop but don't add them to
4552 2002-02-21 <johan AT FRIJA>
