1127 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
1128 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
1129 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1130 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1131 always available in leading double underscore form. The C99 support is

1210 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
1212 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1214 * device/lib/printf_large.c: removed inline assembly for portability and
1215 readability. Use printf_fast if speed or size are more important.
1216 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1217 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1219 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1221 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1222 prevent compiler warning
1224 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1226 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1227 moved to level 0 and declared as static. Also they are explicit
1228 placed in access bank. This was necessery because some times they
1229 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1230 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1231 optimizations. Currently only compare to unsigned char is implemented,
1232 * src/pic16/gen.c: added fReturnIdx array,
1233 * (struct resolvedIfx) is moved to gen.h and made public,
1234 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1235 * (aopForSym): added an optimization to directly store in stack of
1236 the operand of a SEND iCode,
1237 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1238 but as registers instead (AOP_REG) using the fReturnIdx array,
1239 * (pic16_freeAsmop): remove the freed register from the
1240 _G.sregsAlloc field,
1241 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1242 a compare of 'WREG',
1243 * (pic16_popGetTempRegCond): changed function prototype, now
1244 function takes also a bitVector argument v which holds the current
1245 set of registers that are allocated for stack access by aopForSym,
1246 registers allocated in aopForSym for accessing stack symbols are not
1247 any more part of the functions usedRegs field,
1248 * (genCall): some times aopOp is called for a stack variable to be
1249 send, aopForSym might perform the push, if this is true make sure
1250 that genCall doesn't push the variable twice by testing _G.resDirect,
1251 * (genFunction): changed testing for unspecified interrupt number
1252 from 256 to INTNO_UNSPEC,
1253 * modified selection scheme of frame pointer generation. Previously
1254 if function did use local registers a frame pointer was generated,
1255 now a frame pointer is generated only if function has arguments
1256 (that need PLUSW2 register access), or has stack arguments, or the
1257 compiler is not instructed to omit the frame pointer,
1258 * (genEndFunction): before restoring local registers that were saved
1259 in the function preamble, also restore the registers that *might*
1260 have been allocated for stack access,
1261 * (genRet): removed some old comments,
1262 * (genCmp, the active (RN's) version): added a call to the
1263 pic16_genCmp_special function to perform the compare with a more
1264 robust and optimized way,
1265 * (genInline): a feature has been added in inline code generation,
1266 which allows a wildcard variable substitution when writing inline
1267 assembly. Code is incomplete and experimental therefore undocumented,
1268 * (genCast): changed order of aopOp for result and right to allow
1269 aopForSym to directly load the result if possible,
1270 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1271 perform an optimized compare on some selected special occasions,
1272 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1273 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1274 generate an IVT any more,
1275 * src/pic16/main.c (pic16_optionsTable): added command line option
1277 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1278 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1280 * src/pic16/NOTES: Raphael Neider added in list of active developers
1281 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1282 jumptable_end to prevent bug #,
1283 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1284 inCond and outCond fields,
1285 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1286 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1287 turn off register spilling,
1288 * (packRegsForOneUse): synced with other ports' versions although it
1289 is not used currently,
1290 * (pic16_packRegisters): added an optimization while reading
1291 structure bitfields, some registers may be saved (malloc code is
1292 decreased by 80 bytes)
1294 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1296 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1297 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1298 this can be optimized more?
1300 2005-03-10 Raphael Neider <rneider AT web.de>
1302 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1303 genNearPointerGet): (hopefully) fixed access to bitfields via
1304 pointers (p->bitN = x; and x = p->bitN; failed)
1306 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
1308 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"
1310 2005-03-09 Raphael Neider <rneider AT web.de>
1312 * src/SDCCopt.c (killDeadCode): fixed bug #1156016
1314 2005-03-06 Maarten Brock <sourceforge.brock AT dse.nl>
1316 * src/SDCCicode.h: moved CRITICAL and ENDCRITICAL from SKIP_IC2 to SKIP_IC

1939 generated for switch statements. For now you need to set the
1940 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1941 Now 4 algorithms for mcs51 jumptable generation are used:
1942 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

1976 * added libc directory. The current version of LibC contains string
1977 functions, ctype functions and macros and some functions of the
1978 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1979 be extensively tested in the future. Standard disclaimer here.

1992 * (pic16_storeForReturn): optimized return of 0,
1993 * (genCmp): experimental code for new genCmp which uses PIC18's
1994 special compare&skip instructions. Initial tests fail some times
1995 with variables grater than 1 byte in size, so new code is disabled,
1996 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1998 * (genCast): began a fix to optimize the casting of a bit to another
1999 bit, now assigning a bitfield to another bitfield will fail, sorry,

2013 registers when it shouldn't,
2014 * src/pic16/ralloc.c (allocReg): add preliminary support for
2015 supporting a limited set of temporary registers,
2017 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5025 loaded with the linker search paths (-L arguments) and the libraries
5026 to be linked with the current source (-l arguments). Changes
5027 currently will affect only the pic16 port.
5028 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5029 include path the port specific paths and port specific libraries,
5030 * gplink command now contains the $3 argument,
5031 * src/pic16/device.h,

5048 Documenting changes from previous commits.
5049 * configure.in (version 1.56),
5050 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5051 when generating output files to configure the pic16 library,
5052 but now I've commented it out, since gputils aren't installed in the
5053 SF compile farm, so library won't compile
5055 * device/lib/Makefile.in (version 1.56): initially I've added in
5056 target 'all' the prerequestive 'model-pic16' so it compiled the
5057 pic16 library, but now I've commented it out for the same reasons
5059 * added targets 'model-pic16' and 'objects-pic16' to compile the
5061 * added target 'port-specific-objects-pic16' to handle the
5062 generated libraries and copy them into the build/ directory
5063 * added target 'clean-intermediate-pic16' to clean intermediate
5064 files into pic16 directory
5065 * in target 'installdirs' added line to create directory pic16 in

5330 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
5331 * src/SDCCsymt.c (newEnumType),
5333 * support/Util/SDCCerr.c,
5334 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
5336 * support/regression/tests/enum.c: added test for enum values that
5337 require at least 2 bytes of storage.
5339 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5341 * src/common.h: added ifndef/define/endif macros
5342 around the header file.
5343 Bug reported from Jesus Calvino-Fraga
5345 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5347 * sdcc.spec: updated
5348 * device/include/Makefile.in: don't install CVS directories
5349 * device/lib/Makefile.in: added removal of CVS directories after install
5350 * doc/Makefile: fixed install, added local_icons
5351 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5352 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5353 * src/ds390/gen.c (genRightShift): fixed bug #870788
5354 * src/SDCCast.c (decorateType): fixed bug #870781
5356 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5358 PIC16 port related changes:
5359 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5360 added variable stackPos,
5362 * gen.c: genCall, assignResultValue: added support for
5363 pushing/retrieving function parameters to/from stack,
5364 genFunction,genEndFunction: setup stack frame for the
5366 genAddrOf: will be changed according to bug 863624
5368 * added files genutils.c and genutils.h which contain gen*
5369 debugged and optimised functions extracted from gen.c
5371 * glue.c: added variable 'externs' which holds extern symbols,
5372 pic16emitRegularMap: is modified to properly handle relocatable
5373 symbols under the new scheme,
5374 pic16createInterruptVect: is modified
5375 pic16printPublics: is modified to emit 'global' assembler directives,
5376 added pic16_printExterns to print extern symbols,
5377 pic16glue: initializes stack/frame pointer in the beginning of
5378 the assembly output. Temporary hack, will be corrected later,
5379 because gplink yet does not support stack and SDCC does not
5380 yet support a type of crt0.o object to create the final binary.
5382 * Removed many lines that contain 8051 legacy code.
5383 * The code is finally placed under a 'code' directive.
5384 * Added port specific options.
5386 * _process_pragma: simplified since now we do not need *special*
5387 include file to define SFR registers. But a separate header
5388 will be needed. This will be developed later.
5389 * _pic16_parseOptions: added, parses port specific options:
5390 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5391 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5392 --preplace-udata-with=
5394 * _pic16_setDefaultOptions: modified to initialize section names,
5395 but hack is temporarly out of order since it needs improvement.
5396 * _pic16_genAssemblerPreamble: configuration words are emitted by
5397 their address instead of their name. This part is incomplete and
5398 supports only the 18Fxx2 devices. Other devices will emit an error
5399 during assembly since they do not contain the same set of config
5401 * _pic16_genIVT: is modified,
5403 * pcode.c: added definitions for some hardware registers that are needed
5405 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5406 All PCI entries are updated. Now LFSR is supported.
5407 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5408 * added pic16_newpCodeOpLit2 to support instructions with
5409 two literal arguments
5410 * pic16_pCode2str: corrected code that emits assembler instructions
5411 with two literal operands and those that have an access bit modifier
5412 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5413 this fixes a bug which caused some labels to be lost, when an
5414 assembler directive was added, i.e. banksel,
5415 * pic16_FixRegisterBanking: improved logic that causes the insertion
5417 * InlineFunction: functions that are called once, are not any more
5418 inlined. This can be a port option in the future,
5420 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5422 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5423 hold the corresponding uninitialized symbols,
5424 * pic16_allocProcessorRegister: registers have explicit marked the
5426 * pic16_allocInternalRegister: registers are explicit marked as
5428 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5429 processing list, so bit registers were lost,
5432 * ralloc.h: added field 'accessBank' and original symbol operand
5433 in register definition,
5434 * removed the field isMapped from register definition,
5436 ** Several functions have been removed from various sources:
5437 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5438 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5439 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5440 pic16_assignRelocatableRegisters
5442 ** others have been introduced:
5443 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5444 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5446 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5448 * support/scripts/inc2h.pl: changed definition of BIT_AT
5449 to emit 'sbit at' instead of 'bit at'. This was a request.
5451 PIC16 port related preliminary changes:
5452 * gen.c: prefixed function popRegFromString with
5453 pic16_ and all references to it corrected
5454 * pcode.c: all pic16_pc_* hardware registers prefixed
5455 with underscore (_),
5456 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5457 * ralloc.c: newReg(): when register is REG_SFR then
5458 set address to rIdx,
5459 pic16_allocProcessorRegister(): marks register wasUsed=0
5460 pic16_writeUsedRegs(): added a call to assign processor
5461 registers via pic16_assignFixedRegisters
5463 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5465 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5466 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5467 variables in unused register banks. Also the SSEG is placed
5468 wherever there is enough space for it, and IDATA can be anywhere
5469 in internal RAM. For now compile using -Wl-Y[stack_size].
5470 The mem file is different for this option as well, since it
5471 makes no sense of talking about DSEG lenght.
5473 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5475 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5476 in certain cases, e.g. when ROM assignment, patch provided
5477 from Albert den Haan.

5622 * src/mcs51/peephole.def,
5623 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

5718 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5720 * src/SDCCast.c (decorateType): disabled a transformation I added in
5721 revision 1.188 (access to fields of a structure at an absolute address);
5722 it breaks with bitfields, extern declarations, and gcse analysis.
5723 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
5724 could be assigned through a pointer, so don't complain.
5725 * src/SDCCast.c (astErrors),
5727 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

6365 support for standard C idiom of memory mapped variables; for
6366 example, *((xdata int*)0x1234) = 1 is now internally equivalent
6367 to xdata int at 0x1234 tempvar = 1.
6368 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
6369 provided by Akiya ISHIDA

6481 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
6482 fetching of the pointer
6483 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
6484 copied from genNearPointerSet()
6485 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
6486 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

6502 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6503 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6504 type for bits was changed. It resulted in bit variables becoming
6505 global, which is not permitted in PIC 14 assembly output.
6507 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6509 * doc/sdccman.lyx: various additions and updates. Rearranged sections

6522 A few small changes that speed up the peephole optimizer.
6526 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6528 Try to make the peephole optimizer smarter by maintaining
6529 an association between the assembly source code and the
6530 iCodes that originated them. Put this information to use
6531 with a new peephole rule condition "notVolatile" so that
6532 the rules can be aggressive yet still safe.
6537 * src/mcs51/peeph.def
6539 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6543 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6544 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6545 if the left or right operand symbols have the accuse flag set.
6547 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6549 Changed the type of the result of the ! (NOT) operator to char;
6550 previously it returned the same type as the source. This allows
6551 us to eliminate all the genFloatNot functions (all of its target
6552 implementations were very buggy) since !float can use the same

6564 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6565 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6566 during interrupts. Ensure WSAVE is located at a shared bank address.
6567 2. Fixed page selection in some places
6568 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6569 the registers name strings.
6570 4. Fixed "signed / unsigned compare" compiler warnings.
6571 5. The PIC port manages its own allocation of the general purpose
6572 registers, but makes no attempt to reuse them. As a result when
6573 compiling it soon runs out of general purpose registers. Some
6574 additional code was added to the files pcode.c and device.c to walk
6575 through the function call tree and rename the registers so that they
6585 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

6592 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6594 Made bitfield a distinct type from bit so that bitfields
6595 convert as per ANSI C and bits retain their traditional
6596 boolean style behaviour. Implemented bitfield support in
6604 * src/ds390/gen.c: bit v bitfield split
6605 * src/z80/gen.c: New support for bitfields
6606 * support/regression/tests/bitfields.c: reenabled z80,
6609 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6611 Rules 246.x, 247.x relate to bitfields, the others speed up
6612 access to xdata mapped I/O devices.
6614 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6616 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6618 Cleaned up genPackBits and genUnpackBits and added two helper
6619 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6620 for literal assignments in genPackBits (thanks to Frieder for
6626 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6628 Fixed bug #748310 (pointer to function type mishandled when the
6629 function name is omitted). Also fixed a SIGSEGV when a function
6630 attribute (reentrant, etc) is used on a non-function or on a
6631 function but misplaced before the parameter list.
6633 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6635 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
6636 * support/Util/SDCCerr.h,

6658 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6660 Made the constant following the "interrupt" keyword optional. If
6661 omitted, the function will not automatically be given an entry
6662 in the interrupt vector table (similar to #pragma NOIV, but
6663 less syntacticly kludgy). The interrupt number is also now
6664 range checked. Also fixed a bug in the high order bit example

6678 * src/SDCCicode.c (operandOperation): rewritten some ops
6679 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
6680 * src/SDCCsymt.c (computeType): literals are handled the same way as any
6682 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
6683 be re-activated by defining REDUCE_LITERALS)
6684 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
6685 unsigned, but are signed by default
6686 * src/SDCCval.c (constVal): rearranged
6687 * src/SDCCval.c (valMod): preliminary fix
6688 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7194 added if/endif conditional macros to remove options help
7195 messages from optionsTable when a port is not configured, added
7196 support for the PIc16 port in the ports table, when executing
7197 the compiler with no port specified on command line, a default
7198 port is selected with the new macro DEFAULT_PORT which is
7199 defined in port.h, in setDefaultOptions() linkOptions is removed
7200 from initialization assignment, since now it is a set,
7201 parseCmdLine uses setParseWithComma for linkOptions, in
7202 linkEdit() linkOptions are accessed with new function indexSet()
7203 which returns the i'th item of a set variable. See SDCCset.c, in
7204 linkEdit() when calling buildCmdLine(), added linkOptions as
7205 last argument. Now users can pass arguments to gplink via the
7206 -Wl option, main() uses pic16glue() to glue up pic16 programs

7220 gpasm complaining and test the linkage with gplink, _linkCmd and
7221 _asmCmd changed to be more gplink and gpasm friendly
7222 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7223 produced an error when parsed, peep rule 12 is added to utilize
7224 movff, but it is commented out since the pCode does not support
7225 yet a command with 2 address arguments
7227 2003-05-18 <johan AT balder>
7229 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7256 2003-05-11 Borut Razem <borut.razem AT siol.net>
7258 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

8258 2003-01-06 <karl AT turbobit.com>
8259 * sim/ucsim/cmd.src/command.cc: fixed so "break xram r 0x7654" works again in
8262 2003-01-06 <johan AT balder>
8264 * src/SDCCicode.c: fixed array add
8266 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
8267 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
8268 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
8270 2003-01-04 <johan AT balder>
8272 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8274 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8275 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
8277 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
8278 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
8279 * support/regression/tests/bug-524697.c: fit mem usage into 8032
8281 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
8282 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
8284 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
8285 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
8287 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8288 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8290 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8292 * in \sdcc\as\mcs51\ changed these files in order to create an
8293 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8294 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8295 following files to include the previous two files: aslink.dsp,
8296 Makefile.aslink, Makefile.bcc, and Makefile.in.
8298 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8299 .adb instead of .cdb
8301 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8303 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8304 value from option --iram-size.
8306 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8308 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8311 2002-09-18 <wiml AT hhhh.org>
8313 * SDCClrange.h: exposed setFromRange() and setToRange()
8314 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8315 packRegsForAccUse() (bug 542397)
8316 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8317 multiple times and emitting the fetch operations more than once
8318 added aopGetUsesAcc() function to allow binary operators to
8319 fetch their operands in the correct order; made genMinus() emit
8320 compact code for X = LITERAL - Y
8322 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8323 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8324 sprintf() in line 1267.
8326 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8327 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8330 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8331 Changes to aslink (All the changes are marked with 'JCF'):
8333 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8336 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8337 area BSEG. Also moves, if possible, the DATA area down into the internal
8338 ram so more space is available.
8340 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8343 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8344 not bytes. Function summary() which creates a memory usage summary
8345 file with extension .mem. Reports of overlaping stack and small stack
8346 size. If the space for the stack is less than 16 bytes aslink trows a
8349 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8350 the 8051. Option 'y' for memory summary output file.
8352 Changes to sdcc (All the changes are marked with 'JCF'):
8354 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8356 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8357 overlaying area for it (uses RegBankUsed[4]).
8359 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8360 bank zero as used by default. By default aslink locates the stack
8361 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8362 the creation of the .mem file. Delegates the allocation of data area
8363 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8364 the begining of the stack area to aslink.
8366 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8367 glue() in SDCCglue.c creates an area for it.
8369 2002-09-03 Borut Razem <borut.razem AT siol.net>
8370 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8371 sdcc/src/pic/glue.c:
8372 introduced atexit() handler for teporay files removal in case of
8373 errors, assertions, ...
8375 2002-08-29 Borut Razem <borut.razem AT siol.net>
8376 * sdcc/support/cpp2/auto-host_vc_in.h:
8377 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8378 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8379 Maybe there is a similar problem with BORLANDC? It should be checked!
8381 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8382 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8383 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8384 was not executed, and the compiler (cl) launched a warning:
8385 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8387 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8388 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8390 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8391 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8393 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8394 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8395 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8396 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8397 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8398 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8399 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8400 - added Release configuration in VS projects
8401 - review of compiler an linker options
8402 - VC .exe files are generated in bin_vc directory, not to interfere
8403 with binaries generated from other projects (cygwin, mingw, bcc ...)
8405 * sdcc/src/yacc.dsp: added
8407 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8408 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8409 and insert the version number definitions from .version
8411 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8413 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8414 added - genarate auto-host.h using auto-host_vc_in.h as template
8417 removed from CVS, generated automatically
8419 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8420 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8422 2002-08-11 Borut Razem <borut.razem AT siol.net>
8423 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8425 2002-08-10 Borut Razem <borut.razem AT siol.net>
8426 * src/SDCCmain.c (main):
8427 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8428 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8429 The consequence was that some temporary files were not removed.
8432 unification of code in functions tempfilename() and tempfile():
8433 function tempnam() is defined in Visual Studio 6.0 and .NET
8435 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8437 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8438 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8439 - removed compiler command line option /WX: Treats all warnings as errors
8440 - update a list of source files, included into the project
8442 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8443 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8444 changed project type to Generic Project so that can be correcly converted to VS.NET project
8446 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8448 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8450 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8452 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8453 added return 0 statements after assert() to make compiler happy
8455 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8456 added newline in the def file to keep MSC compiler satisfied
8458 * sdcc/src/z80/gen.c:
8459 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8460 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8461 - solved MSC error in function aopDump()
8463 * sdcc_vc.h: define PREFIX as "\\sdcc"
8465 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8466 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

8469 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
8470 - Rewrote the register banking algorithm.
8471 - Added pCode live-range analysis to registers (for now, only non-used and
8472 singly-used registers optimized away)
8474 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
8476 * 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.

8503 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
8505 2002-03-28 Johan Knol <johan AT balder>
8507 * src/SDCCval.c: fixed bug #532436
8509 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8511 Added "char *Processor" field to the port structure.
8514 Added -p option. Allows port dependent processor to be specified.
8517 Initialized the new field char *Processor field to NULL in all ports
8520 Compiler generated registers for interrupt context saving
8521 were not getting allocated.
8523 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8526 Fixed left shift. Will promote the left side of a left shift
8527 if a) left shifting more than size of operand or b) when assigned
8528 to something size > size of left side
8530 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8532 tons of changes. Register allocation has been
8533 rewritten. Added customization for the various PICs. Flow
8534 analysis is restructured. ...
8540 Added. device.c is a PIC port hack to accomodate variations
8543 2002-03-13 Michael Hope <michaelh AT vroom>
8545 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
8547 2002-03-04 johanknol <johanknol AT manik>

8554 2002-03-04 bela <bela AT manik>
8556 * /device/include/mcs51reg.h:
8557 ds89c420 register definition update
8559 2002-03-03 <johan AT FRIJA>

8638 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
8640 * sdcc/src/SDCCloop.c:
8641 Previous fix was not good. basic blocks that have "break" or "return" are
8642 not really partof a loop , but live ranges used in these blocks should
8643 be live thru the entire loop, so set partOfLoop but don't add them to
8646 2002-02-21 <johan AT FRIJA>
8648 * src/SDCCcse.c: fixed bug #514308
8650 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
8653 Fixed BUG #519583. If a conditional block ended in a return/break
8654 statement inside a loop, it was not being considered part of the loop.
8656 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
8658 2002-02-10 Karl Bongers <karl AT turbobit.com>
8661 Fixed up SDCDB debugger somewhat. Updated debugger/README
8662 with lots of comments and notes.
8664 * device/examples/test2.c:
8665 Fix bug, "red" variable not being initialized(compiler complained).
8667 * device/examples/Makefile, examples/test3.c:
8668 Add Makefile in device/examples folder, compiles test3.c
8669 for use as a multiple module SDCDB test case.
8671 * sim/ucsim/cmd.src/cmdset.cc:
8672 Took out debug printfs in ucsim "next" command.
8675 Karl and Johan start ucsim XA support. Most dissassembly working,
8676 about 75% emulation done(plenty of work remaining).
8678 * sim/ucsim/z80.src:
8679 Add Z80 support to ucsim, add test-ucz80 regression test,
8680 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
8681 Notice z80 compiler fails on examples/test3.c/crc code.

8701 * src/SDCCsymt.c, src/SDCCsymt.h:
8702 changes to handle multiple sends & receives
8705 added some pointer arithmetic optimization
8708 added some pointer arithmetic optimizations but not stable yet so not
8709 called from anywhere (will get this working shortly)
8711 * src/SDCCopt.c: fixed for multiple sends & receives
8714 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
8715 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
8716 set preprocessor defines (depending on options)
8718 * src/SDCCicode.c, src/SDCCicode.h:
8719 changes made to handle multiple sends & receives
8722 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
