1141 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
1142 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
1143 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1144 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1145 always available in leading double underscore form. The C99 support is
1146 mostly missing, but it's a start.
1147 * support/regression/tests/bug-227710.c: fixed nonconforming use of
1148 reserved identifier "__data".

1196 2005-03-20 Borut Razem <borut.razem AT siol.net>
1198 * support/scripts/inc2h.pl: WIN32 port

1224 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
1226 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1228 * device/lib/printf_large.c: removed inline assembly for portability and
1229 readability. Use printf_fast if speed or size are more important.
1230 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1231 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1233 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1235 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1236 prevent compiler warning
1238 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1240 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1241 moved to level 0 and declared as static. Also they are explicit
1242 placed in access bank. This was necessery because some times they
1243 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1244 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1245 optimizations. Currently only compare to unsigned char is implemented,
1246 * src/pic16/gen.c: added fReturnIdx array,
1247 * (struct resolvedIfx) is moved to gen.h and made public,
1248 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1249 * (aopForSym): added an optimization to directly store in stack of
1250 the operand of a SEND iCode,
1251 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1252 but as registers instead (AOP_REG) using the fReturnIdx array,
1253 * (pic16_freeAsmop): remove the freed register from the
1254 _G.sregsAlloc field,
1255 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1256 a compare of 'WREG',
1257 * (pic16_popGetTempRegCond): changed function prototype, now
1258 function takes also a bitVector argument v which holds the current
1259 set of registers that are allocated for stack access by aopForSym,
1260 registers allocated in aopForSym for accessing stack symbols are not
1261 any more part of the functions usedRegs field,
1262 * (genCall): some times aopOp is called for a stack variable to be
1263 send, aopForSym might perform the push, if this is true make sure
1264 that genCall doesn't push the variable twice by testing _G.resDirect,
1265 * (genFunction): changed testing for unspecified interrupt number
1266 from 256 to INTNO_UNSPEC,
1267 * modified selection scheme of frame pointer generation. Previously
1268 if function did use local registers a frame pointer was generated,
1269 now a frame pointer is generated only if function has arguments
1270 (that need PLUSW2 register access), or has stack arguments, or the
1271 compiler is not instructed to omit the frame pointer,
1272 * (genEndFunction): before restoring local registers that were saved
1273 in the function preamble, also restore the registers that *might*
1274 have been allocated for stack access,
1275 * (genRet): removed some old comments,
1276 * (genCmp, the active (RN's) version): added a call to the
1277 pic16_genCmp_special function to perform the compare with a more
1278 robust and optimized way,
1279 * (genInline): a feature has been added in inline code generation,
1280 which allows a wildcard variable substitution when writing inline
1281 assembly. Code is incomplete and experimental therefore undocumented,
1282 * (genCast): changed order of aopOp for result and right to allow
1283 aopForSym to directly load the result if possible,
1284 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1285 perform an optimized compare on some selected special occasions,
1286 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1287 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1288 generate an IVT any more,
1289 * src/pic16/main.c (pic16_optionsTable): added command line option
1291 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1292 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1294 * src/pic16/NOTES: Raphael Neider added in list of active developers
1295 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1296 jumptable_end to prevent bug #,
1297 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1298 inCond and outCond fields,
1299 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1300 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1301 turn off register spilling,
1302 * (packRegsForOneUse): synced with other ports' versions although it
1303 is not used currently,
1304 * (pic16_packRegisters): added an optimization while reading
1305 structure bitfields, some registers may be saved (malloc code is
1306 decreased by 80 bytes)
1308 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1310 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1311 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1312 this can be optimized more?
1314 2005-03-10 Raphael Neider <rneider AT web.de>

1952 Adding support for replacing ljmps with sjmps in jumptables
1953 generated for switch statements. For now you need to set the
1954 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1955 Now 4 algorithms for mcs51 jumptable generation are used:
1956 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1957 addresses loaded pc-relative for up to 112 cases and stack-pushing

1990 * added libc directory. The current version of LibC contains string
1991 functions, ctype functions and macros and some functions of the
1992 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1993 be extensively tested in the future. Standard disclaimer here.

2006 * (pic16_storeForReturn): optimized return of 0,
2007 * (genCmp): experimental code for new genCmp which uses PIC18's
2008 special compare&skip instructions. Initial tests fail some times
2009 with variables grater than 1 byte in size, so new code is disabled,
2010 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2012 * (genCast): began a fix to optimize the casting of a bit to another
2013 bit, now assigning a bitfield to another bitfield will fail, sorry,

2028 * src/pic16/ralloc.c (allocReg): add preliminary support for
2029 supporting a limited set of temporary registers,

5039 loaded with the linker search paths (-L arguments) and the libraries
5040 to be linked with the current source (-l arguments). Changes
5041 currently will affect only the pic16 port.
5042 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5043 include path the port specific paths and port specific libraries,
5044 * gplink command now contains the $3 argument,

5062 Documenting changes from previous commits.
5063 * configure.in (version 1.56),
5064 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5065 when generating output files to configure the pic16 library,
5066 but now I've commented it out, since gputils aren't installed in the
5067 SF compile farm, so library won't compile
5069 * device/lib/Makefile.in (version 1.56): initially I've added in
5070 target 'all' the prerequestive 'model-pic16' so it compiled the
5071 pic16 library, but now I've commented it out for the same reasons
5073 * added targets 'model-pic16' and 'objects-pic16' to compile the
5075 * added target 'port-specific-objects-pic16' to handle the
5076 generated libraries and copy them into the build/ directory
5077 * added target 'clean-intermediate-pic16' to clean intermediate
5078 files into pic16 directory
5079 * in target 'installdirs' added line to create directory pic16 in

5083 added lines to copy all header files to installation path,
5084 * in target 'installdirs' added line create directory for pic16
5085 headers in the installation path

5325 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
5326 LEFT_OP (left shift)
5328 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5330 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5331 (default behaviour).
5333 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5335 A python script to validate compiler diagnostic messages. It can be
5336 used to verify that sdcc complains about bad c source code and
5337 gives a good location of the error.
5338 * support/valdiag/Makefile,
5339 * support/valdiag/valdiag.py,
5340 * support/valdiag/tests/*
5342 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5344 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
5345 * src/SDCCsymt.c (newEnumType),
5347 * support/Util/SDCCerr.c,
5348 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
5350 * support/regression/tests/enum.c: added test for enum values that
5351 require at least 2 bytes of storage.
5353 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5355 * src/common.h: added ifndef/define/endif macros
5356 around the header file.
5357 Bug reported from Jesus Calvino-Fraga
5359 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5361 * sdcc.spec: updated
5362 * device/include/Makefile.in: don't install CVS directories
5363 * device/lib/Makefile.in: added removal of CVS directories after install
5364 * doc/Makefile: fixed install, added local_icons
5365 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5366 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5367 * src/ds390/gen.c (genRightShift): fixed bug #870788
5368 * src/SDCCast.c (decorateType): fixed bug #870781
5370 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5372 PIC16 port related changes:
5373 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5374 added variable stackPos,
5376 * gen.c: genCall, assignResultValue: added support for
5377 pushing/retrieving function parameters to/from stack,
5378 genFunction,genEndFunction: setup stack frame for the
5380 genAddrOf: will be changed according to bug 863624
5382 * added files genutils.c and genutils.h which contain gen*
5383 debugged and optimised functions extracted from gen.c
5385 * glue.c: added variable 'externs' which holds extern symbols,
5386 pic16emitRegularMap: is modified to properly handle relocatable
5387 symbols under the new scheme,
5388 pic16createInterruptVect: is modified
5389 pic16printPublics: is modified to emit 'global' assembler directives,
5390 added pic16_printExterns to print extern symbols,
5391 pic16glue: initializes stack/frame pointer in the beginning of
5392 the assembly output. Temporary hack, will be corrected later,
5393 because gplink yet does not support stack and SDCC does not
5394 yet support a type of crt0.o object to create the final binary.
5396 * Removed many lines that contain 8051 legacy code.
5397 * The code is finally placed under a 'code' directive.
5398 * Added port specific options.
5400 * _process_pragma: simplified since now we do not need *special*
5401 include file to define SFR registers. But a separate header
5402 will be needed. This will be developed later.
5403 * _pic16_parseOptions: added, parses port specific options:
5404 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5405 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5406 --preplace-udata-with=
5408 * _pic16_setDefaultOptions: modified to initialize section names,
5409 but hack is temporarly out of order since it needs improvement.
5410 * _pic16_genAssemblerPreamble: configuration words are emitted by
5411 their address instead of their name. This part is incomplete and
5412 supports only the 18Fxx2 devices. Other devices will emit an error
5413 during assembly since they do not contain the same set of config
5415 * _pic16_genIVT: is modified,
5417 * pcode.c: added definitions for some hardware registers that are needed
5419 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5420 All PCI entries are updated. Now LFSR is supported.
5421 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5422 * added pic16_newpCodeOpLit2 to support instructions with
5423 two literal arguments
5424 * pic16_pCode2str: corrected code that emits assembler instructions
5425 with two literal operands and those that have an access bit modifier
5426 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5427 this fixes a bug which caused some labels to be lost, when an
5428 assembler directive was added, i.e. banksel,
5429 * pic16_FixRegisterBanking: improved logic that causes the insertion
5431 * InlineFunction: functions that are called once, are not any more
5432 inlined. This can be a port option in the future,
5434 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5436 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5437 hold the corresponding uninitialized symbols,
5438 * pic16_allocProcessorRegister: registers have explicit marked the
5440 * pic16_allocInternalRegister: registers are explicit marked as
5442 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5443 processing list, so bit registers were lost,
5446 * ralloc.h: added field 'accessBank' and original symbol operand
5447 in register definition,
5448 * removed the field isMapped from register definition,
5450 ** Several functions have been removed from various sources:
5451 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5452 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5453 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5454 pic16_assignRelocatableRegisters
5456 ** others have been introduced:
5457 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5458 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5460 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5462 * support/scripts/inc2h.pl: changed definition of BIT_AT
5463 to emit 'sbit at' instead of 'bit at'. This was a request.
5465 PIC16 port related preliminary changes:
5466 * gen.c: prefixed function popRegFromString with
5467 pic16_ and all references to it corrected
5468 * pcode.c: all pic16_pc_* hardware registers prefixed
5469 with underscore (_),
5470 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5471 * ralloc.c: newReg(): when register is REG_SFR then
5472 set address to rIdx,
5473 pic16_allocProcessorRegister(): marks register wasUsed=0
5474 pic16_writeUsedRegs(): added a call to assign processor
5475 registers via pic16_assignFixedRegisters
5477 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5479 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5480 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5481 variables in unused register banks. Also the SSEG is placed
5482 wherever there is enough space for it, and IDATA can be anywhere
5483 in internal RAM. For now compile using -Wl-Y[stack_size].
5484 The mem file is different for this option as well, since it
5485 makes no sense of talking about DSEG lenght.
5487 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5489 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5490 in certain cases, e.g. when ROM assignment, patch provided
5491 from Albert den Haan.
5493 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5636 * src/mcs51/peephole.def,
5637 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

5649 multiply defined with mismatching "at" address.
5651 2003-12-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5653 * src/ds390/main.c (PORT tininative_port): fixed bug #858416

5732 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5734 * src/SDCCast.c (decorateType): disabled a transformation I added in
5735 revision 1.188 (access to fields of a structure at an absolute address);
5736 it breaks with bitfields, extern declarations, and gcse analysis.
5737 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
5738 could be assigned through a pointer, so don't complain.
5739 * src/SDCCast.c (astErrors),
5741 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

6376 * src/SDCCsymt.c (sclsFromPtr),
6378 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
6379 support for standard C idiom of memory mapped variables; for
6380 example, *((xdata int*)0x1234) = 1 is now internally equivalent
6381 to xdata int at 0x1234 tempvar = 1.
6382 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
6383 provided by Akiya ISHIDA

6399 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6401 Fixed bug #621531 (const & volatile confusion in the type chain).
6402 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
6403 refer to the const or volatile state of the pointer itself.

6494 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
6495 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
6496 fetching of the pointer
6497 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
6498 copied from genNearPointerSet()
6499 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
6500 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
6501 If they pop r0/r1 they must be called in the opposite order than aopOp().
6502 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
6503 (resp. --stack-auto), prepared for --xstack

6514 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
6516 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6517 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6518 type for bits was changed. It resulted in bit variables becoming
6519 global, which is not permitted in PIC 14 assembly output.
6521 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6523 * doc/sdccman.lyx: various additions and updates. Rearranged sections

6536 A few small changes that speed up the peephole optimizer.
6540 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6542 Try to make the peephole optimizer smarter by maintaining
6543 an association between the assembly source code and the
6544 iCodes that originated them. Put this information to use
6545 with a new peephole rule condition "notVolatile" so that
6546 the rules can be aggressive yet still safe.
6551 * src/mcs51/peeph.def
6553 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6557 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6558 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6559 if the left or right operand symbols have the accuse flag set.
6561 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6563 Changed the type of the result of the ! (NOT) operator to char;
6564 previously it returned the same type as the source. This allows
6565 us to eliminate all the genFloatNot functions (all of its target
6566 implementations were very buggy) since !float can use the same

6578 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6579 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6580 during interrupts. Ensure WSAVE is located at a shared bank address.
6581 2. Fixed page selection in some places
6582 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6583 the registers name strings.
6584 4. Fixed "signed / unsigned compare" compiler warnings.
6585 5. The PIC port manages its own allocation of the general purpose
6586 registers, but makes no attempt to reuse them. As a result when
6587 compiling it soon runs out of general purpose registers. Some
6588 additional code was added to the files pcode.c and device.c to walk
6589 through the function call tree and rename the registers so that they
6599 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6600 genPlus() & genMinus() when the result is the same as left or right
6602 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6606 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6608 Made bitfield a distinct type from bit so that bitfields
6609 convert as per ANSI C and bits retain their traditional
6610 boolean style behaviour. Implemented bitfield support in
6618 * src/ds390/gen.c: bit v bitfield split
6619 * src/z80/gen.c: New support for bitfields
6620 * support/regression/tests/bitfields.c: reenabled z80,
6623 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6625 Rules 246.x, 247.x relate to bitfields, the others speed up
6626 access to xdata mapped I/O devices.
6628 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6630 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6632 Cleaned up genPackBits and genUnpackBits and added two helper
6633 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6634 for literal assignments in genPackBits (thanks to Frieder for
6640 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6642 Fixed bug #748310 (pointer to function type mishandled when the
6643 function name is omitted). Also fixed a SIGSEGV when a function
6644 attribute (reentrant, etc) is used on a non-function or on a
6645 function but misplaced before the parameter list.
6647 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6649 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
6650 * support/Util/SDCCerr.h,
6651 * support/Util/SDCCerr.c: Added func attr misuse error msg

6672 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6674 Made the constant following the "interrupt" keyword optional. If
6675 omitted, the function will not automatically be given an entry
6676 in the interrupt vector table (similar to #pragma NOIV, but
6677 less syntacticly kludgy). The interrupt number is also now
6678 range checked. Also fixed a bug in the high order bit example

6692 * src/SDCCicode.c (operandOperation): rewritten some ops
6693 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
6694 * src/SDCCsymt.c (computeType): literals are handled the same way as any
6696 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
6697 be re-activated by defining REDUCE_LITERALS)
6698 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
6699 unsigned, but are signed by default
6700 * src/SDCCval.c (constVal): rearranged
6701 * src/SDCCval.c (valMod): preliminary fix
6702 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7208 added if/endif conditional macros to remove options help
7209 messages from optionsTable when a port is not configured, added
7210 support for the PIc16 port in the ports table, when executing
7211 the compiler with no port specified on command line, a default
7212 port is selected with the new macro DEFAULT_PORT which is
7213 defined in port.h, in setDefaultOptions() linkOptions is removed
7214 from initialization assignment, since now it is a set,
7215 parseCmdLine uses setParseWithComma for linkOptions, in
7216 linkEdit() linkOptions are accessed with new function indexSet()
7217 which returns the i'th item of a set variable. See SDCCset.c, in
7218 linkEdit() when calling buildCmdLine(), added linkOptions as
7219 last argument. Now users can pass arguments to gplink via the
7220 -Wl option, main() uses pic16glue() to glue up pic16 programs

7234 gpasm complaining and test the linkage with gplink, _linkCmd and
7235 _asmCmd changed to be more gplink and gpasm friendly
7236 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7237 produced an error when parsed, peep rule 12 is added to utilize
7238 movff, but it is commented out since the pCode does not support
7239 yet a command with 2 address arguments
7241 2003-05-18 <johan AT balder>
7243 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7270 2003-05-11 Borut Razem <borut.razem AT siol.net>
7272 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

8258 2003-01-09 Bernhard Held <bernhard AT bernhardheld.de>
8259 * src/mcs51/gen.c (genPlus): replaced "mov b,acc" by "mov b,a" Fiorenzo D. Ramaglia <fd.ramaglia AT tin.it>
8261 2003-01-07 <johan AT balder>
8263 * src/SDCCast.c (decorateType): fixed bug #600035
8265 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
8266 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings

8276 2003-01-06 <johan AT balder>
8278 * src/SDCCicode.c: fixed array add
8280 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
8281 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
8282 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
8284 2003-01-04 <johan AT balder>
8286 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8288 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8289 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
8291 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
8292 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
8293 * support/regression/tests/bug-524697.c: fit mem usage into 8032
8295 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
8296 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
8298 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
8299 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
8301 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8302 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8304 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8306 * in \sdcc\as\mcs51\ changed these files in order to create an
8307 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8308 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8309 following files to include the previous two files: aslink.dsp,
8310 Makefile.aslink, Makefile.bcc, and Makefile.in.
8312 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8313 .adb instead of .cdb
8315 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8317 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8318 value from option --iram-size.
8320 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8322 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8325 2002-09-18 <wiml AT hhhh.org>
8327 * SDCClrange.h: exposed setFromRange() and setToRange()
8328 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8329 packRegsForAccUse() (bug 542397)
8330 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8331 multiple times and emitting the fetch operations more than once
8332 added aopGetUsesAcc() function to allow binary operators to
8333 fetch their operands in the correct order; made genMinus() emit
8334 compact code for X = LITERAL - Y
8336 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8337 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8338 sprintf() in line 1267.
8340 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8341 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8344 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8345 Changes to aslink (All the changes are marked with 'JCF'):
8347 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8350 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8351 area BSEG. Also moves, if possible, the DATA area down into the internal
8352 ram so more space is available.
8354 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8357 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8358 not bytes. Function summary() which creates a memory usage summary
8359 file with extension .mem. Reports of overlaping stack and small stack
8360 size. If the space for the stack is less than 16 bytes aslink trows a
8363 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8364 the 8051. Option 'y' for memory summary output file.
8366 Changes to sdcc (All the changes are marked with 'JCF'):
8368 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8370 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8371 overlaying area for it (uses RegBankUsed[4]).
8373 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8374 bank zero as used by default. By default aslink locates the stack
8375 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8376 the creation of the .mem file. Delegates the allocation of data area
8377 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8378 the begining of the stack area to aslink.
8380 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8381 glue() in SDCCglue.c creates an area for it.
8383 2002-09-03 Borut Razem <borut.razem AT siol.net>
8384 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8385 sdcc/src/pic/glue.c:
8386 introduced atexit() handler for teporay files removal in case of
8387 errors, assertions, ...
8389 2002-08-29 Borut Razem <borut.razem AT siol.net>
8390 * sdcc/support/cpp2/auto-host_vc_in.h:
8391 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8392 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8393 Maybe there is a similar problem with BORLANDC? It should be checked!
8395 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8396 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8397 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8398 was not executed, and the compiler (cl) launched a warning:
8399 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8401 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8402 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8404 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8405 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8407 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8408 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8409 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8410 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8411 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8412 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8413 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8414 - added Release configuration in VS projects
8415 - review of compiler an linker options
8416 - VC .exe files are generated in bin_vc directory, not to interfere
8417 with binaries generated from other projects (cygwin, mingw, bcc ...)
8419 * sdcc/src/yacc.dsp: added
8421 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8422 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8423 and insert the version number definitions from .version
8425 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8427 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8428 added - genarate auto-host.h using auto-host_vc_in.h as template
8431 removed from CVS, generated automatically
8433 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8434 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8436 2002-08-11 Borut Razem <borut.razem AT siol.net>
8437 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8439 2002-08-10 Borut Razem <borut.razem AT siol.net>
8440 * src/SDCCmain.c (main):
8441 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8442 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8443 The consequence was that some temporary files were not removed.
8446 unification of code in functions tempfilename() and tempfile():
8447 function tempnam() is defined in Visual Studio 6.0 and .NET
8449 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8451 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8452 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8453 - removed compiler command line option /WX: Treats all warnings as errors
8454 - update a list of source files, included into the project
8456 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8457 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8458 changed project type to Generic Project so that can be correcly converted to VS.NET project
8460 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8462 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8464 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8466 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8467 added return 0 statements after assert() to make compiler happy
8469 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8470 added newline in the def file to keep MSC compiler satisfied
8472 * sdcc/src/z80/gen.c:
8473 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8474 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8475 - solved MSC error in function aopDump()
8477 * sdcc_vc.h: define PREFIX as "\\sdcc"
8479 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8480 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
8482 2002-06-22 Scott Dattalo <scott AT dattalo.com>
8483 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
8484 - Rewrote the register banking algorithm.
8485 - Added pCode live-range analysis to registers (for now, only non-used and
8486 singly-used registers optimized away)
8488 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
8490 * 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.

8515 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
8517 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
8519 2002-03-28 Johan Knol <johan AT balder>
8521 * src/SDCCval.c: fixed bug #532436
8523 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8525 Added "char *Processor" field to the port structure.
8528 Added -p option. Allows port dependent processor to be specified.
8531 Initialized the new field char *Processor field to NULL in all ports
8534 Compiler generated registers for interrupt context saving
8535 were not getting allocated.
8537 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8540 Fixed left shift. Will promote the left side of a left shift
8541 if a) left shifting more than size of operand or b) when assigned
8542 to something size > size of left side
8544 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8546 tons of changes. Register allocation has been
8547 rewritten. Added customization for the various PICs. Flow
8548 analysis is restructured. ...
8554 Added. device.c is a PIC port hack to accomodate variations
8557 2002-03-13 Michael Hope <michaelh AT vroom>
8559 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
8561 2002-03-04 johanknol <johanknol AT manik>
8563 * /src/SDCCval.c: fixed
8565 const unsigned char arr[][2] = { { 0, 1 } };
8566 t18.c:1: error: Initializer element is not constant
8568 2002-03-04 bela <bela AT manik>
8570 * /device/include/mcs51reg.h:
8571 ds89c420 register definition update
8573 2002-03-03 <johan AT FRIJA>

8652 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
8654 * sdcc/src/SDCCloop.c:
8655 Previous fix was not good. basic blocks that have "break" or "return" are
8656 not really partof a loop , but live ranges used in these blocks should
8657 be live thru the entire loop, so set partOfLoop but don't add them to
8660 2002-02-21 <johan AT FRIJA>
8662 * src/SDCCcse.c: fixed bug #514308
8664 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
8667 Fixed BUG #519583. If a conditional block ended in a return/break
8668 statement inside a loop, it was not being considered part of the loop.
8670 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
8672 2002-02-10 Karl Bongers <karl AT turbobit.com>
8675 Fixed up SDCDB debugger somewhat. Updated debugger/README
8676 with lots of comments and notes.
8678 * device/examples/test2.c:
8679 Fix bug, "red" variable not being initialized(compiler complained).
8681 * device/examples/Makefile, examples/test3.c:
8682 Add Makefile in device/examples folder, compiles test3.c
8683 for use as a multiple module SDCDB test case.
8685 * sim/ucsim/cmd.src/cmdset.cc:
8686 Took out debug printfs in ucsim "next" command.
8689 Karl and Johan start ucsim XA support. Most dissassembly working,
8690 about 75% emulation done(plenty of work remaining).
8692 * sim/ucsim/z80.src:
8693 Add Z80 support to ucsim, add test-ucz80 regression test,
8694 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
8695 Notice z80 compiler fails on examples/test3.c/crc code.
8697 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>

8709 3) added __builtin_swapw swap bytes of a short
8711 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
8712 1) handle multiple send & receives from register bank1
8713 2) ralloc can now allocate DPTR1 to some liveRanges
8715 * src/SDCCsymt.c, src/SDCCsymt.h:
8716 changes to handle multiple sends & receives
8719 added some pointer arithmetic optimization
8722 added some pointer arithmetic optimizations but not stable yet so not
8723 called from anywhere (will get this working shortly)
8725 * src/SDCCopt.c: fixed for multiple sends & receives
8728 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
8729 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
8730 set preprocessor defines (depending on options)
8732 * src/SDCCicode.c, src/SDCCicode.h:
8733 changes made to handle multiple sends & receives
8736 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
