1130 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1132 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
1133 * src/z80/main.c (_keywords[]),
1134 * src/SDCCglobal.h (struct options),
1136 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
1137 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
1138 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1139 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1140 always available in leading double underscore form. The C99 support is
1141 mostly missing, but it's a start.
1142 * support/regression/tests/bug-227710.c: fixed nonconforming use of
1143 reserved identifier "__data".

1199 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
1201 * device/include/stdint.h: added
1202 * device/lib/abs.c: added

1219 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
1221 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1223 * device/lib/printf_large.c: removed inline assembly for portability and
1224 readability. Use printf_fast if speed or size are more important.
1225 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1226 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1228 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1230 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1231 prevent compiler warning
1233 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1235 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1236 moved to level 0 and declared as static. Also they are explicit
1237 placed in access bank. This was necessery because some times they
1238 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1239 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1240 optimizations. Currently only compare to unsigned char is implemented,
1241 * src/pic16/gen.c: added fReturnIdx array,
1242 * (struct resolvedIfx) is moved to gen.h and made public,
1243 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1244 * (aopForSym): added an optimization to directly store in stack of
1245 the operand of a SEND iCode,
1246 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1247 but as registers instead (AOP_REG) using the fReturnIdx array,
1248 * (pic16_freeAsmop): remove the freed register from the
1249 _G.sregsAlloc field,
1250 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1251 a compare of 'WREG',
1252 * (pic16_popGetTempRegCond): changed function prototype, now
1253 function takes also a bitVector argument v which holds the current
1254 set of registers that are allocated for stack access by aopForSym,
1255 registers allocated in aopForSym for accessing stack symbols are not
1256 any more part of the functions usedRegs field,
1257 * (genCall): some times aopOp is called for a stack variable to be
1258 send, aopForSym might perform the push, if this is true make sure
1259 that genCall doesn't push the variable twice by testing _G.resDirect,
1260 * (genFunction): changed testing for unspecified interrupt number
1261 from 256 to INTNO_UNSPEC,
1262 * modified selection scheme of frame pointer generation. Previously
1263 if function did use local registers a frame pointer was generated,
1264 now a frame pointer is generated only if function has arguments
1265 (that need PLUSW2 register access), or has stack arguments, or the
1266 compiler is not instructed to omit the frame pointer,
1267 * (genEndFunction): before restoring local registers that were saved
1268 in the function preamble, also restore the registers that *might*
1269 have been allocated for stack access,
1270 * (genRet): removed some old comments,
1271 * (genCmp, the active (RN's) version): added a call to the
1272 pic16_genCmp_special function to perform the compare with a more
1273 robust and optimized way,
1274 * (genInline): a feature has been added in inline code generation,
1275 which allows a wildcard variable substitution when writing inline
1276 assembly. Code is incomplete and experimental therefore undocumented,
1277 * (genCast): changed order of aopOp for result and right to allow
1278 aopForSym to directly load the result if possible,
1279 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1280 perform an optimized compare on some selected special occasions,
1281 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1282 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1283 generate an IVT any more,
1284 * src/pic16/main.c (pic16_optionsTable): added command line option
1286 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1287 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1289 * src/pic16/NOTES: Raphael Neider added in list of active developers
1290 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1291 jumptable_end to prevent bug #,
1292 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1293 inCond and outCond fields,
1294 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1295 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1296 turn off register spilling,
1297 * (packRegsForOneUse): synced with other ports' versions although it
1298 is not used currently,
1299 * (pic16_packRegisters): added an optimization while reading
1300 structure bitfields, some registers may be saved (malloc code is
1301 decreased by 80 bytes)
1303 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1305 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1306 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1307 this can be optimized more?
1309 2005-03-10 Raphael Neider <rneider AT web.de>
1311 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1312 genNearPointerGet): (hopefully) fixed access to bitfields via

1948 generated for switch statements. For now you need to set the
1949 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1950 Now 4 algorithms for mcs51 jumptable generation are used:
1951 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

1986 functions, ctype functions and macros and some functions of the
1987 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1988 be extensively tested in the future. Standard disclaimer here.

2002 * (genCmp): experimental code for new genCmp which uses PIC18's
2003 special compare&skip instructions. Initial tests fail some times
2004 with variables grater than 1 byte in size, so new code is disabled,
2005 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2007 * (genCast): began a fix to optimize the casting of a bit to another
2008 bit, now assigning a bitfield to another bitfield will fail, sorry,

5034 loaded with the linker search paths (-L arguments) and the libraries
5035 to be linked with the current source (-l arguments). Changes
5036 currently will affect only the pic16 port.
5037 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5038 include path the port specific paths and port specific libraries,
5039 * gplink command now contains the $3 argument,

5057 Documenting changes from previous commits.
5058 * configure.in (version 1.56),
5059 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5060 when generating output files to configure the pic16 library,
5061 but now I've commented it out, since gputils aren't installed in the
5062 SF compile farm, so library won't compile
5064 * device/lib/Makefile.in (version 1.56): initially I've added in
5065 target 'all' the prerequestive 'model-pic16' so it compiled the
5066 pic16 library, but now I've commented it out for the same reasons
5068 * added targets 'model-pic16' and 'objects-pic16' to compile the
5070 * added target 'port-specific-objects-pic16' to handle the
5071 generated libraries and copy them into the build/ directory
5072 * added target 'clean-intermediate-pic16' to clean intermediate
5073 files into pic16 directory
5074 * in target 'installdirs' added line to create directory pic16 in

5078 added lines to copy all header files to installation path,
5079 * in target 'installdirs' added line create directory for pic16
5080 headers in the installation path

5323 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5325 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5326 (default behaviour).
5328 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5330 A python script to validate compiler diagnostic messages. It can be
5331 used to verify that sdcc complains about bad c source code and
5332 gives a good location of the error.
5333 * support/valdiag/Makefile,
5334 * support/valdiag/valdiag.py,
5335 * support/valdiag/tests/*
5337 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5339 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
5340 * src/SDCCsymt.c (newEnumType),
5342 * support/Util/SDCCerr.c,
5343 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
5345 * support/regression/tests/enum.c: added test for enum values that
5346 require at least 2 bytes of storage.
5348 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5350 * src/common.h: added ifndef/define/endif macros
5351 around the header file.
5352 Bug reported from Jesus Calvino-Fraga
5354 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5356 * sdcc.spec: updated
5357 * device/include/Makefile.in: don't install CVS directories
5358 * device/lib/Makefile.in: added removal of CVS directories after install
5359 * doc/Makefile: fixed install, added local_icons
5360 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5361 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5362 * src/ds390/gen.c (genRightShift): fixed bug #870788
5363 * src/SDCCast.c (decorateType): fixed bug #870781
5365 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5367 PIC16 port related changes:
5368 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5369 added variable stackPos,
5371 * gen.c: genCall, assignResultValue: added support for
5372 pushing/retrieving function parameters to/from stack,
5373 genFunction,genEndFunction: setup stack frame for the
5375 genAddrOf: will be changed according to bug 863624
5377 * added files genutils.c and genutils.h which contain gen*
5378 debugged and optimised functions extracted from gen.c
5380 * glue.c: added variable 'externs' which holds extern symbols,
5381 pic16emitRegularMap: is modified to properly handle relocatable
5382 symbols under the new scheme,
5383 pic16createInterruptVect: is modified
5384 pic16printPublics: is modified to emit 'global' assembler directives,
5385 added pic16_printExterns to print extern symbols,
5386 pic16glue: initializes stack/frame pointer in the beginning of
5387 the assembly output. Temporary hack, will be corrected later,
5388 because gplink yet does not support stack and SDCC does not
5389 yet support a type of crt0.o object to create the final binary.
5391 * Removed many lines that contain 8051 legacy code.
5392 * The code is finally placed under a 'code' directive.
5393 * Added port specific options.
5395 * _process_pragma: simplified since now we do not need *special*
5396 include file to define SFR registers. But a separate header
5397 will be needed. This will be developed later.
5398 * _pic16_parseOptions: added, parses port specific options:
5399 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5400 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5401 --preplace-udata-with=
5403 * _pic16_setDefaultOptions: modified to initialize section names,
5404 but hack is temporarly out of order since it needs improvement.
5405 * _pic16_genAssemblerPreamble: configuration words are emitted by
5406 their address instead of their name. This part is incomplete and
5407 supports only the 18Fxx2 devices. Other devices will emit an error
5408 during assembly since they do not contain the same set of config
5410 * _pic16_genIVT: is modified,
5412 * pcode.c: added definitions for some hardware registers that are needed
5414 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5415 All PCI entries are updated. Now LFSR is supported.
5416 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5417 * added pic16_newpCodeOpLit2 to support instructions with
5418 two literal arguments
5419 * pic16_pCode2str: corrected code that emits assembler instructions
5420 with two literal operands and those that have an access bit modifier
5421 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5422 this fixes a bug which caused some labels to be lost, when an
5423 assembler directive was added, i.e. banksel,
5424 * pic16_FixRegisterBanking: improved logic that causes the insertion
5426 * InlineFunction: functions that are called once, are not any more
5427 inlined. This can be a port option in the future,
5429 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5431 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5432 hold the corresponding uninitialized symbols,
5433 * pic16_allocProcessorRegister: registers have explicit marked the
5435 * pic16_allocInternalRegister: registers are explicit marked as
5437 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5438 processing list, so bit registers were lost,
5441 * ralloc.h: added field 'accessBank' and original symbol operand
5442 in register definition,
5443 * removed the field isMapped from register definition,
5445 ** Several functions have been removed from various sources:
5446 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5447 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5448 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5449 pic16_assignRelocatableRegisters
5451 ** others have been introduced:
5452 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5453 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5455 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5457 * support/scripts/inc2h.pl: changed definition of BIT_AT
5458 to emit 'sbit at' instead of 'bit at'. This was a request.
5460 PIC16 port related preliminary changes:
5461 * gen.c: prefixed function popRegFromString with
5462 pic16_ and all references to it corrected
5463 * pcode.c: all pic16_pc_* hardware registers prefixed
5464 with underscore (_),
5465 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5466 * ralloc.c: newReg(): when register is REG_SFR then
5467 set address to rIdx,
5468 pic16_allocProcessorRegister(): marks register wasUsed=0
5469 pic16_writeUsedRegs(): added a call to assign processor
5470 registers via pic16_assignFixedRegisters
5472 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5474 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5475 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5476 variables in unused register banks. Also the SSEG is placed
5477 wherever there is enough space for it, and IDATA can be anywhere
5478 in internal RAM. For now compile using -Wl-Y[stack_size].
5479 The mem file is different for this option as well, since it
5480 makes no sense of talking about DSEG lenght.
5482 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5484 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5485 in certain cases, e.g. when ROM assignment, patch provided
5486 from Albert den Haan.
5488 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5631 * src/mcs51/peephole.def,
5632 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

5644 multiply defined with mismatching "at" address.
5646 2003-12-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5648 * src/ds390/main.c (PORT tininative_port): fixed bug #858416

5727 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5729 * src/SDCCast.c (decorateType): disabled a transformation I added in
5730 revision 1.188 (access to fields of a structure at an absolute address);
5731 it breaks with bitfields, extern declarations, and gcse analysis.
5732 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
5733 could be assigned through a pointer, so don't complain.
5734 * src/SDCCast.c (astErrors),
5736 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

6371 * src/SDCCsymt.c (sclsFromPtr),
6373 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
6374 support for standard C idiom of memory mapped variables; for
6375 example, *((xdata int*)0x1234) = 1 is now internally equivalent
6376 to xdata int at 0x1234 tempvar = 1.
6377 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
6378 provided by Akiya ISHIDA

6394 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6396 Fixed bug #621531 (const & volatile confusion in the type chain).
6397 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
6398 refer to the const or volatile state of the pointer itself.

6489 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
6490 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
6491 fetching of the pointer
6492 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
6493 copied from genNearPointerSet()
6494 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
6495 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
6496 If they pop r0/r1 they must be called in the opposite order than aopOp().
6497 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
6498 (resp. --stack-auto), prepared for --xstack

6509 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
6511 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6512 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6513 type for bits was changed. It resulted in bit variables becoming
6514 global, which is not permitted in PIC 14 assembly output.
6516 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6518 * doc/sdccman.lyx: various additions and updates. Rearranged sections

6531 A few small changes that speed up the peephole optimizer.
6535 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6537 Try to make the peephole optimizer smarter by maintaining
6538 an association between the assembly source code and the
6539 iCodes that originated them. Put this information to use
6540 with a new peephole rule condition "notVolatile" so that
6541 the rules can be aggressive yet still safe.
6546 * src/mcs51/peeph.def
6548 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6552 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6553 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6554 if the left or right operand symbols have the accuse flag set.
6556 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6558 Changed the type of the result of the ! (NOT) operator to char;
6559 previously it returned the same type as the source. This allows
6560 us to eliminate all the genFloatNot functions (all of its target
6561 implementations were very buggy) since !float can use the same
6564 * src/SDCCicode.c (ast2iCode): ! returns char

6573 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6574 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6575 during interrupts. Ensure WSAVE is located at a shared bank address.
6576 2. Fixed page selection in some places
6577 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6578 the registers name strings.
6579 4. Fixed "signed / unsigned compare" compiler warnings.
6580 5. The PIC port manages its own allocation of the general purpose
6581 registers, but makes no attempt to reuse them. As a result when
6582 compiling it soon runs out of general purpose registers. Some
6583 additional code was added to the files pcode.c and device.c to walk
6584 through the function call tree and rename the registers so that they
6594 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6595 genPlus() & genMinus() when the result is the same as left or right

6601 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6603 Made bitfield a distinct type from bit so that bitfields
6604 convert as per ANSI C and bits retain their traditional
6605 boolean style behaviour. Implemented bitfield support in
6613 * src/ds390/gen.c: bit v bitfield split
6614 * src/z80/gen.c: New support for bitfields
6615 * support/regression/tests/bitfields.c: reenabled z80,
6618 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6620 Rules 246.x, 247.x relate to bitfields, the others speed up
6621 access to xdata mapped I/O devices.
6623 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6625 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6627 Cleaned up genPackBits and genUnpackBits and added two helper
6628 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6629 for literal assignments in genPackBits (thanks to Frieder for
6635 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6637 Fixed bug #748310 (pointer to function type mishandled when the
6638 function name is omitted). Also fixed a SIGSEGV when a function
6639 attribute (reentrant, etc) is used on a non-function or on a
6640 function but misplaced before the parameter list.
6642 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6644 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
6645 * support/Util/SDCCerr.h,
6646 * support/Util/SDCCerr.c: Added func attr misuse error msg

6667 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6669 Made the constant following the "interrupt" keyword optional. If
6670 omitted, the function will not automatically be given an entry
6671 in the interrupt vector table (similar to #pragma NOIV, but
6672 less syntacticly kludgy). The interrupt number is also now
6673 range checked. Also fixed a bug in the high order bit example

6687 * src/SDCCicode.c (operandOperation): rewritten some ops
6688 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
6689 * src/SDCCsymt.c (computeType): literals are handled the same way as any
6691 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
6692 be re-activated by defining REDUCE_LITERALS)
6693 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
6694 unsigned, but are signed by default
6695 * src/SDCCval.c (constVal): rearranged
6696 * src/SDCCval.c (valMod): preliminary fix
6697 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6739 constants are unsigned; added recognition of "u" flag for unsigned
6740 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
6741 * src/SDCCval.c (valDiv, valMod): fixed signdness
6742 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
6743 signedness of modulo, left and right shift

7202 * src/SDCCmain.c: linkOptions is changed to set *,
7203 added if/endif conditional macros to remove options help
7204 messages from optionsTable when a port is not configured, added
7205 support for the PIc16 port in the ports table, when executing
7206 the compiler with no port specified on command line, a default
7207 port is selected with the new macro DEFAULT_PORT which is
7208 defined in port.h, in setDefaultOptions() linkOptions is removed
7209 from initialization assignment, since now it is a set,
7210 parseCmdLine uses setParseWithComma for linkOptions, in
7211 linkEdit() linkOptions are accessed with new function indexSet()
7212 which returns the i'th item of a set variable. See SDCCset.c, in
7213 linkEdit() when calling buildCmdLine(), added linkOptions as
7214 last argument. Now users can pass arguments to gplink via the
7215 -Wl option, main() uses pic16glue() to glue up pic16 programs

7229 gpasm complaining and test the linkage with gplink, _linkCmd and
7230 _asmCmd changed to be more gplink and gpasm friendly
7231 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7232 produced an error when parsed, peep rule 12 is added to utilize
7233 movff, but it is commented out since the pCode does not support
7234 yet a command with 2 address arguments
7236 2003-05-18 <johan AT balder>
7238 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7265 2003-05-11 Borut Razem <borut.razem AT siol.net>
7267 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

8254 * src/mcs51/gen.c (genPlus): replaced "mov b,acc" by "mov b,a" Fiorenzo D. Ramaglia <fd.ramaglia AT tin.it>
8256 2003-01-07 <johan AT balder>
8258 * src/SDCCast.c (decorateType): fixed bug #600035
8260 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
8261 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings
8262 * as/mcs51/lkaomf51.c: #include <ctype.h> to remove warnings
8263 * src/pic/main.c (_hasNativeMulFor): outcommented unused variables to remove warnings
8264 * src/pic/pcode.c: outcommented unused variable to remove warnings
8265 * src/pic/ralloc.c: outcommented unused variable to remove warnings
8267 2003-01-06 <karl AT turbobit.com>
8268 * sim/ucsim/cmd.src/command.cc: fixed so "break xram r 0x7654" works again in
8271 2003-01-06 <johan AT balder>
8273 * src/SDCCicode.c: fixed array add
8275 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
8276 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
8277 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
8279 2003-01-04 <johan AT balder>
8281 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8283 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8284 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
8286 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
8287 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
8288 * support/regression/tests/bug-524697.c: fit mem usage into 8032
8290 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
8291 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
8293 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
8294 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
8296 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8297 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8299 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8301 * in \sdcc\as\mcs51\ changed these files in order to create an
8302 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8303 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8304 following files to include the previous two files: aslink.dsp,
8305 Makefile.aslink, Makefile.bcc, and Makefile.in.
8307 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8308 .adb instead of .cdb
8310 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8312 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8313 value from option --iram-size.
8315 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8317 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8320 2002-09-18 <wiml AT hhhh.org>
8322 * SDCClrange.h: exposed setFromRange() and setToRange()
8323 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8324 packRegsForAccUse() (bug 542397)
8325 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8326 multiple times and emitting the fetch operations more than once
8327 added aopGetUsesAcc() function to allow binary operators to
8328 fetch their operands in the correct order; made genMinus() emit
8329 compact code for X = LITERAL - Y
8331 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8332 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8333 sprintf() in line 1267.
8335 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8336 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8339 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8340 Changes to aslink (All the changes are marked with 'JCF'):
8342 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8345 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8346 area BSEG. Also moves, if possible, the DATA area down into the internal
8347 ram so more space is available.
8349 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8352 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8353 not bytes. Function summary() which creates a memory usage summary
8354 file with extension .mem. Reports of overlaping stack and small stack
8355 size. If the space for the stack is less than 16 bytes aslink trows a
8358 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8359 the 8051. Option 'y' for memory summary output file.
8361 Changes to sdcc (All the changes are marked with 'JCF'):
8363 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8365 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8366 overlaying area for it (uses RegBankUsed[4]).
8368 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8369 bank zero as used by default. By default aslink locates the stack
8370 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8371 the creation of the .mem file. Delegates the allocation of data area
8372 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8373 the begining of the stack area to aslink.
8375 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8376 glue() in SDCCglue.c creates an area for it.
8378 2002-09-03 Borut Razem <borut.razem AT siol.net>
8379 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8380 sdcc/src/pic/glue.c:
8381 introduced atexit() handler for teporay files removal in case of
8382 errors, assertions, ...
8384 2002-08-29 Borut Razem <borut.razem AT siol.net>
8385 * sdcc/support/cpp2/auto-host_vc_in.h:
8386 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8387 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8388 Maybe there is a similar problem with BORLANDC? It should be checked!
8390 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8391 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8392 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8393 was not executed, and the compiler (cl) launched a warning:
8394 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8396 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8397 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8399 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8400 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8402 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8403 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8404 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8405 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8406 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8407 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8408 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8409 - added Release configuration in VS projects
8410 - review of compiler an linker options
8411 - VC .exe files are generated in bin_vc directory, not to interfere
8412 with binaries generated from other projects (cygwin, mingw, bcc ...)
8414 * sdcc/src/yacc.dsp: added
8416 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8417 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8418 and insert the version number definitions from .version
8420 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8422 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8423 added - genarate auto-host.h using auto-host_vc_in.h as template
8426 removed from CVS, generated automatically
8428 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8429 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8431 2002-08-11 Borut Razem <borut.razem AT siol.net>
8432 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8434 2002-08-10 Borut Razem <borut.razem AT siol.net>
8435 * src/SDCCmain.c (main):
8436 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8437 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8438 The consequence was that some temporary files were not removed.
8441 unification of code in functions tempfilename() and tempfile():
8442 function tempnam() is defined in Visual Studio 6.0 and .NET
8444 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8446 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8447 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8448 - removed compiler command line option /WX: Treats all warnings as errors
8449 - update a list of source files, included into the project
8451 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8452 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8453 changed project type to Generic Project so that can be correcly converted to VS.NET project
8455 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8457 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8459 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8461 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8462 added return 0 statements after assert() to make compiler happy
8464 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8465 added newline in the def file to keep MSC compiler satisfied
8467 * sdcc/src/z80/gen.c:
8468 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8469 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8470 - solved MSC error in function aopDump()
8472 * sdcc_vc.h: define PREFIX as "\\sdcc"
8474 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8475 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
8477 2002-06-22 Scott Dattalo <scott AT dattalo.com>
8478 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
8479 - Rewrote the register banking algorithm.
8480 - Added pCode live-range analysis to registers (for now, only non-used and
8481 singly-used registers optimized away)
8483 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
8485 * 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.
8487 2002-05-10 Scott Dattalo <scott AT dattalo.com>
8488 * src/pic/*: Added support for multiplication. Fixed many,many bugs.

8510 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
8512 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
8514 2002-03-28 Johan Knol <johan AT balder>
8516 * src/SDCCval.c: fixed bug #532436
8518 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8520 Added "char *Processor" field to the port structure.
8523 Added -p option. Allows port dependent processor to be specified.
8526 Initialized the new field char *Processor field to NULL in all ports
8529 Compiler generated registers for interrupt context saving
8530 were not getting allocated.
8532 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8535 Fixed left shift. Will promote the left side of a left shift
8536 if a) left shifting more than size of operand or b) when assigned
8537 to something size > size of left side
8539 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8541 tons of changes. Register allocation has been
8542 rewritten. Added customization for the various PICs. Flow
8543 analysis is restructured. ...
8549 Added. device.c is a PIC port hack to accomodate variations
8552 2002-03-13 Michael Hope <michaelh AT vroom>
8554 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
8556 2002-03-04 johanknol <johanknol AT manik>
8558 * /src/SDCCval.c: fixed
8560 const unsigned char arr[][2] = { { 0, 1 } };
8561 t18.c:1: error: Initializer element is not constant
8563 2002-03-04 bela <bela AT manik>
8565 * /device/include/mcs51reg.h:
8566 ds89c420 register definition update
8568 2002-03-03 <johan AT FRIJA>

8647 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
8649 * sdcc/src/SDCCloop.c:
8650 Previous fix was not good. basic blocks that have "break" or "return" are
8651 not really partof a loop , but live ranges used in these blocks should
8652 be live thru the entire loop, so set partOfLoop but don't add them to
8655 2002-02-21 <johan AT FRIJA>
8657 * src/SDCCcse.c: fixed bug #514308
8659 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
8662 Fixed BUG #519583. If a conditional block ended in a return/break
8663 statement inside a loop, it was not being considered part of the loop.
8665 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
8667 2002-02-10 Karl Bongers <karl AT turbobit.com>
8670 Fixed up SDCDB debugger somewhat. Updated debugger/README
8671 with lots of comments and notes.
8673 * device/examples/test2.c:
8674 Fix bug, "red" variable not being initialized(compiler complained).
8676 * device/examples/Makefile, examples/test3.c:
8677 Add Makefile in device/examples folder, compiles test3.c
8678 for use as a multiple module SDCDB test case.
8680 * sim/ucsim/cmd.src/cmdset.cc:
8681 Took out debug printfs in ucsim "next" command.
8684 Karl and Johan start ucsim XA support. Most dissassembly working,
8685 about 75% emulation done(plenty of work remaining).
8687 * sim/ucsim/z80.src:
8688 Add Z80 support to ucsim, add test-ucz80 regression test,
8689 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
8690 Notice z80 compiler fails on examples/test3.c/crc code.
8692 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>

8704 3) added __builtin_swapw swap bytes of a short
8706 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
8707 1) handle multiple send & receives from register bank1
8708 2) ralloc can now allocate DPTR1 to some liveRanges
8710 * src/SDCCsymt.c, src/SDCCsymt.h:
8711 changes to handle multiple sends & receives
8714 added some pointer arithmetic optimization
8717 added some pointer arithmetic optimizations but not stable yet so not
8718 called from anywhere (will get this working shortly)
8720 * src/SDCCopt.c: fixed for multiple sends & receives
8723 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
8724 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
8725 set preprocessor defines (depending on options)
8727 * src/SDCCicode.c, src/SDCCicode.h:
8728 changes made to handle multiple sends & receives
8731 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
