1115 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
1116 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
1117 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1118 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1119 always available in leading double underscore form. The C99 support is
1120 mostly missing, but it's a start.
1121 * support/regression/tests/bug-227710.c: fixed nonconforming use of
1122 reserved identifier "__data".
1124 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

1200 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1202 * device/lib/printf_large.c: removed inline assembly for portability and
1203 readability. Use printf_fast if speed or size are more important.
1204 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1205 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1207 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1209 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1210 prevent compiler warning
1212 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1214 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1215 moved to level 0 and declared as static. Also they are explicit
1216 placed in access bank. This was necessery because some times they
1217 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1218 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1219 optimizations. Currently only compare to unsigned char is implemented,
1220 * src/pic16/gen.c: added fReturnIdx array,
1221 * (struct resolvedIfx) is moved to gen.h and made public,
1222 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1223 * (aopForSym): added an optimization to directly store in stack of
1224 the operand of a SEND iCode,
1225 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1226 but as registers instead (AOP_REG) using the fReturnIdx array,
1227 * (pic16_freeAsmop): remove the freed register from the
1228 _G.sregsAlloc field,
1229 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1230 a compare of 'WREG',
1231 * (pic16_popGetTempRegCond): changed function prototype, now
1232 function takes also a bitVector argument v which holds the current
1233 set of registers that are allocated for stack access by aopForSym,
1234 registers allocated in aopForSym for accessing stack symbols are not
1235 any more part of the functions usedRegs field,
1236 * (genCall): some times aopOp is called for a stack variable to be
1237 send, aopForSym might perform the push, if this is true make sure
1238 that genCall doesn't push the variable twice by testing _G.resDirect,
1239 * (genFunction): changed testing for unspecified interrupt number
1240 from 256 to INTNO_UNSPEC,
1241 * modified selection scheme of frame pointer generation. Previously
1242 if function did use local registers a frame pointer was generated,
1243 now a frame pointer is generated only if function has arguments
1244 (that need PLUSW2 register access), or has stack arguments, or the
1245 compiler is not instructed to omit the frame pointer,
1246 * (genEndFunction): before restoring local registers that were saved
1247 in the function preamble, also restore the registers that *might*
1248 have been allocated for stack access,
1249 * (genRet): removed some old comments,
1250 * (genCmp, the active (RN's) version): added a call to the
1251 pic16_genCmp_special function to perform the compare with a more
1252 robust and optimized way,
1253 * (genInline): a feature has been added in inline code generation,
1254 which allows a wildcard variable substitution when writing inline
1255 assembly. Code is incomplete and experimental therefore undocumented,
1256 * (genCast): changed order of aopOp for result and right to allow
1257 aopForSym to directly load the result if possible,
1258 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1259 perform an optimized compare on some selected special occasions,
1260 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1261 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1262 generate an IVT any more,
1263 * src/pic16/main.c (pic16_optionsTable): added command line option
1265 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1266 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1268 * src/pic16/NOTES: Raphael Neider added in list of active developers
1269 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1270 jumptable_end to prevent bug #,
1271 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1272 inCond and outCond fields,
1273 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1274 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1275 turn off register spilling,
1276 * (packRegsForOneUse): synced with other ports' versions although it
1277 is not used currently,
1278 * (pic16_packRegisters): added an optimization while reading
1279 structure bitfields, some registers may be saved (malloc code is
1280 decreased by 80 bytes)
1282 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1284 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1285 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1286 this can be optimized more?
1288 2005-03-10 Raphael Neider <rneider AT web.de>
1290 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1291 genNearPointerGet): (hopefully) fixed access to bitfields via
1292 pointers (p->bitN = x; and x = p->bitN; failed)
1294 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
1296 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

1926 Adding support for replacing ljmps with sjmps in jumptables
1927 generated for switch statements. For now you need to set the
1928 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1929 Now 4 algorithms for mcs51 jumptable generation are used:
1930 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

1962 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1964 * added libc directory. The current version of LibC contains string
1965 functions, ctype functions and macros and some functions of the
1966 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1967 be extensively tested in the future. Standard disclaimer here.
1968 Library is not automatically build yet. But one can build it by
1969 invoking 'make' inside the libc directory.

1980 * (pic16_storeForReturn): optimized return of 0,
1981 * (genCmp): experimental code for new genCmp which uses PIC18's
1982 special compare&skip instructions. Initial tests fail some times
1983 with variables grater than 1 byte in size, so new code is disabled,
1984 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1986 * (genCast): began a fix to optimize the casting of a bit to another
1987 bit, now assigning a bitfield to another bitfield will fail, sorry,

1998 caused stop processing pCodes after a inline assembly block,
1999 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

2001 registers when it shouldn't,
2002 * src/pic16/ralloc.c (allocReg): add preliminary support for
2003 supporting a limited set of temporary registers,
2005 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2007 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,

2011 (genFunction): optimize RECEIVE iCodes in reentrant functions
2013 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2015 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

5013 loaded with the linker search paths (-L arguments) and the libraries
5014 to be linked with the current source (-l arguments). Changes
5015 currently will affect only the pic16 port.
5016 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5017 include path the port specific paths and port specific libraries,
5018 * gplink command now contains the $3 argument,

5036 Documenting changes from previous commits.
5037 * configure.in (version 1.56),
5038 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5039 when generating output files to configure the pic16 library,
5040 but now I've commented it out, since gputils aren't installed in the
5041 SF compile farm, so library won't compile
5043 * device/lib/Makefile.in (version 1.56): initially I've added in
5044 target 'all' the prerequestive 'model-pic16' so it compiled the
5045 pic16 library, but now I've commented it out for the same reasons
5047 * added targets 'model-pic16' and 'objects-pic16' to compile the
5049 * added target 'port-specific-objects-pic16' to handle the
5050 generated libraries and copy them into the build/ directory
5051 * added target 'clean-intermediate-pic16' to clean intermediate
5052 files into pic16 directory
5053 * in target 'installdirs' added line to create directory pic16 in

5057 added lines to copy all header files to installation path,
5058 * in target 'installdirs' added line create directory for pic16
5059 headers in the installation path

5336 * device/include/Makefile.in: don't install CVS directories
5337 * device/lib/Makefile.in: added removal of CVS directories after install
5338 * doc/Makefile: fixed install, added local_icons
5339 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5340 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5341 * src/ds390/gen.c (genRightShift): fixed bug #870788
5342 * src/SDCCast.c (decorateType): fixed bug #870781
5344 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5346 PIC16 port related changes:
5347 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5348 added variable stackPos,
5350 * gen.c: genCall, assignResultValue: added support for
5351 pushing/retrieving function parameters to/from stack,
5352 genFunction,genEndFunction: setup stack frame for the
5354 genAddrOf: will be changed according to bug 863624
5356 * added files genutils.c and genutils.h which contain gen*
5357 debugged and optimised functions extracted from gen.c
5359 * glue.c: added variable 'externs' which holds extern symbols,
5360 pic16emitRegularMap: is modified to properly handle relocatable
5361 symbols under the new scheme,
5362 pic16createInterruptVect: is modified
5363 pic16printPublics: is modified to emit 'global' assembler directives,
5364 added pic16_printExterns to print extern symbols,
5365 pic16glue: initializes stack/frame pointer in the beginning of
5366 the assembly output. Temporary hack, will be corrected later,
5367 because gplink yet does not support stack and SDCC does not
5368 yet support a type of crt0.o object to create the final binary.
5370 * Removed many lines that contain 8051 legacy code.
5371 * The code is finally placed under a 'code' directive.
5372 * Added port specific options.
5374 * _process_pragma: simplified since now we do not need *special*
5375 include file to define SFR registers. But a separate header
5376 will be needed. This will be developed later.
5377 * _pic16_parseOptions: added, parses port specific options:
5378 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5379 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5380 --preplace-udata-with=
5382 * _pic16_setDefaultOptions: modified to initialize section names,
5383 but hack is temporarly out of order since it needs improvement.
5384 * _pic16_genAssemblerPreamble: configuration words are emitted by
5385 their address instead of their name. This part is incomplete and
5386 supports only the 18Fxx2 devices. Other devices will emit an error
5387 during assembly since they do not contain the same set of config
5389 * _pic16_genIVT: is modified,
5391 * pcode.c: added definitions for some hardware registers that are needed
5393 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5394 All PCI entries are updated. Now LFSR is supported.
5395 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5396 * added pic16_newpCodeOpLit2 to support instructions with
5397 two literal arguments
5398 * pic16_pCode2str: corrected code that emits assembler instructions
5399 with two literal operands and those that have an access bit modifier
5400 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5401 this fixes a bug which caused some labels to be lost, when an
5402 assembler directive was added, i.e. banksel,
5403 * pic16_FixRegisterBanking: improved logic that causes the insertion
5405 * InlineFunction: functions that are called once, are not any more
5406 inlined. This can be a port option in the future,
5408 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5410 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5411 hold the corresponding uninitialized symbols,
5412 * pic16_allocProcessorRegister: registers have explicit marked the
5414 * pic16_allocInternalRegister: registers are explicit marked as
5416 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5417 processing list, so bit registers were lost,
5420 * ralloc.h: added field 'accessBank' and original symbol operand
5421 in register definition,
5422 * removed the field isMapped from register definition,
5424 ** Several functions have been removed from various sources:
5425 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5426 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5427 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5428 pic16_assignRelocatableRegisters
5430 ** others have been introduced:
5431 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5432 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5434 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5436 * support/scripts/inc2h.pl: changed definition of BIT_AT
5437 to emit 'sbit at' instead of 'bit at'. This was a request.
5439 PIC16 port related preliminary changes:
5440 * gen.c: prefixed function popRegFromString with
5441 pic16_ and all references to it corrected
5442 * pcode.c: all pic16_pc_* hardware registers prefixed
5443 with underscore (_),
5444 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5445 * ralloc.c: newReg(): when register is REG_SFR then
5446 set address to rIdx,
5447 pic16_allocProcessorRegister(): marks register wasUsed=0
5448 pic16_writeUsedRegs(): added a call to assign processor
5449 registers via pic16_assignFixedRegisters
5451 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5453 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5454 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5455 variables in unused register banks. Also the SSEG is placed
5456 wherever there is enough space for it, and IDATA can be anywhere
5457 in internal RAM. For now compile using -Wl-Y[stack_size].
5458 The mem file is different for this option as well, since it
5459 makes no sense of talking about DSEG lenght.
5461 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5463 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5464 in certain cases, e.g. when ROM assignment, patch provided
5465 from Albert den Haan.
5467 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5706 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5708 * src/SDCCast.c (decorateType): disabled a transformation I added in
5709 revision 1.188 (access to fields of a structure at an absolute address);
5710 it breaks with bitfields, extern declarations, and gcse analysis.
5711 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
5712 could be assigned through a pointer, so don't complain.
5713 * src/SDCCast.c (astErrors),
5715 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

6373 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6375 Fixed bug #621531 (const & volatile confusion in the type chain).
6376 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

6469 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
6470 fetching of the pointer
6471 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
6472 copied from genNearPointerSet()
6473 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
6474 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

6488 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
6490 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6491 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6492 type for bits was changed. It resulted in bit variables becoming
6493 global, which is not permitted in PIC 14 assembly output.
6495 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6497 * doc/sdccman.lyx: various additions and updates. Rearranged sections

6510 A few small changes that speed up the peephole optimizer.
6514 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6516 Try to make the peephole optimizer smarter by maintaining
6517 an association between the assembly source code and the
6518 iCodes that originated them. Put this information to use
6519 with a new peephole rule condition "notVolatile" so that
6520 the rules can be aggressive yet still safe.
6525 * src/mcs51/peeph.def
6527 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6531 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6532 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6533 if the left or right operand symbols have the accuse flag set.
6535 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6537 Changed the type of the result of the ! (NOT) operator to char;
6538 previously it returned the same type as the source. This allows
6539 us to eliminate all the genFloatNot functions (all of its target
6540 implementations were very buggy) since !float can use the same
6543 * src/SDCCicode.c (ast2iCode): ! returns char

6552 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6553 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6554 during interrupts. Ensure WSAVE is located at a shared bank address.
6555 2. Fixed page selection in some places
6556 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6557 the registers name strings.
6558 4. Fixed "signed / unsigned compare" compiler warnings.
6559 5. The PIC port manages its own allocation of the general purpose
6560 registers, but makes no attempt to reuse them. As a result when
6561 compiling it soon runs out of general purpose registers. Some
6562 additional code was added to the files pcode.c and device.c to walk
6563 through the function call tree and rename the registers so that they
6573 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6574 genPlus() & genMinus() when the result is the same as left or right

6580 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6582 Made bitfield a distinct type from bit so that bitfields
6583 convert as per ANSI C and bits retain their traditional
6584 boolean style behaviour. Implemented bitfield support in
6592 * src/ds390/gen.c: bit v bitfield split
6593 * src/z80/gen.c: New support for bitfields
6594 * support/regression/tests/bitfields.c: reenabled z80,
6597 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6599 Rules 246.x, 247.x relate to bitfields, the others speed up
6600 access to xdata mapped I/O devices.
6602 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6604 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6606 Cleaned up genPackBits and genUnpackBits and added two helper
6607 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6608 for literal assignments in genPackBits (thanks to Frieder for
6614 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6616 Fixed bug #748310 (pointer to function type mishandled when the
6617 function name is omitted). Also fixed a SIGSEGV when a function
6618 attribute (reentrant, etc) is used on a non-function or on a
6619 function but misplaced before the parameter list.
6621 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6623 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
6624 * support/Util/SDCCerr.h,
6625 * support/Util/SDCCerr.c: Added func attr misuse error msg

6646 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6648 Made the constant following the "interrupt" keyword optional. If
6649 omitted, the function will not automatically be given an entry
6650 in the interrupt vector table (similar to #pragma NOIV, but
6651 less syntacticly kludgy). The interrupt number is also now
6652 range checked. Also fixed a bug in the high order bit example

6665 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
6666 * src/SDCCicode.c (operandOperation): rewritten some ops
6667 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
6668 * src/SDCCsymt.c (computeType): literals are handled the same way as any
6670 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
6671 be re-activated by defining REDUCE_LITERALS)
6672 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
6673 unsigned, but are signed by default
6674 * src/SDCCval.c (constVal): rearranged
6675 * src/SDCCval.c (valMod): preliminary fix
6676 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6719 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
6720 * src/SDCCval.c (valDiv, valMod): fixed signdness
6721 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
6722 signedness of modulo, left and right shift

7182 added if/endif conditional macros to remove options help
7183 messages from optionsTable when a port is not configured, added
7184 support for the PIc16 port in the ports table, when executing
7185 the compiler with no port specified on command line, a default
7186 port is selected with the new macro DEFAULT_PORT which is
7187 defined in port.h, in setDefaultOptions() linkOptions is removed
7188 from initialization assignment, since now it is a set,
7189 parseCmdLine uses setParseWithComma for linkOptions, in
7190 linkEdit() linkOptions are accessed with new function indexSet()
7191 which returns the i'th item of a set variable. See SDCCset.c, in
7192 linkEdit() when calling buildCmdLine(), added linkOptions as
7193 last argument. Now users can pass arguments to gplink via the
7194 -Wl option, main() uses pic16glue() to glue up pic16 programs

7208 gpasm complaining and test the linkage with gplink, _linkCmd and
7209 _asmCmd changed to be more gplink and gpasm friendly
7210 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7211 produced an error when parsed, peep rule 12 is added to utilize
7212 movff, but it is commented out since the pCode does not support
7213 yet a command with 2 address arguments
7215 2003-05-18 <johan AT balder>
7217 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7244 2003-05-11 Borut Razem <borut.razem AT siol.net>
7246 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

8260 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8262 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8263 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
8265 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
8266 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
8267 * support/regression/tests/bug-524697.c: fit mem usage into 8032
8269 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
8270 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
8272 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
8273 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
8275 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8276 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8278 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8280 * in \sdcc\as\mcs51\ changed these files in order to create an
8281 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8282 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8283 following files to include the previous two files: aslink.dsp,
8284 Makefile.aslink, Makefile.bcc, and Makefile.in.
8286 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8287 .adb instead of .cdb
8289 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8291 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8292 value from option --iram-size.
8294 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8296 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8299 2002-09-18 <wiml AT hhhh.org>
8301 * SDCClrange.h: exposed setFromRange() and setToRange()
8302 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8303 packRegsForAccUse() (bug 542397)
8304 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8305 multiple times and emitting the fetch operations more than once
8306 added aopGetUsesAcc() function to allow binary operators to
8307 fetch their operands in the correct order; made genMinus() emit
8308 compact code for X = LITERAL - Y
8310 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8311 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8312 sprintf() in line 1267.
8314 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8315 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8318 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8319 Changes to aslink (All the changes are marked with 'JCF'):
8321 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8324 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8325 area BSEG. Also moves, if possible, the DATA area down into the internal
8326 ram so more space is available.
8328 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8331 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8332 not bytes. Function summary() which creates a memory usage summary
8333 file with extension .mem. Reports of overlaping stack and small stack
8334 size. If the space for the stack is less than 16 bytes aslink trows a
8337 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8338 the 8051. Option 'y' for memory summary output file.
8340 Changes to sdcc (All the changes are marked with 'JCF'):
8342 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8344 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8345 overlaying area for it (uses RegBankUsed[4]).
8347 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8348 bank zero as used by default. By default aslink locates the stack
8349 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8350 the creation of the .mem file. Delegates the allocation of data area
8351 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8352 the begining of the stack area to aslink.
8354 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8355 glue() in SDCCglue.c creates an area for it.
8357 2002-09-03 Borut Razem <borut.razem AT siol.net>
8358 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8359 sdcc/src/pic/glue.c:
8360 introduced atexit() handler for teporay files removal in case of
8361 errors, assertions, ...
8363 2002-08-29 Borut Razem <borut.razem AT siol.net>
8364 * sdcc/support/cpp2/auto-host_vc_in.h:
8365 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8366 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8367 Maybe there is a similar problem with BORLANDC? It should be checked!
8369 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8370 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8371 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8372 was not executed, and the compiler (cl) launched a warning:
8373 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8375 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8376 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8378 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8379 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8381 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8382 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8383 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8384 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8385 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8386 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8387 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8388 - added Release configuration in VS projects
8389 - review of compiler an linker options
8390 - VC .exe files are generated in bin_vc directory, not to interfere
8391 with binaries generated from other projects (cygwin, mingw, bcc ...)
8393 * sdcc/src/yacc.dsp: added
8395 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8396 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8397 and insert the version number definitions from .version
8399 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8401 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8402 added - genarate auto-host.h using auto-host_vc_in.h as template
8405 removed from CVS, generated automatically
8407 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8408 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8410 2002-08-11 Borut Razem <borut.razem AT siol.net>
8411 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8413 2002-08-10 Borut Razem <borut.razem AT siol.net>
8414 * src/SDCCmain.c (main):
8415 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8416 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8417 The consequence was that some temporary files were not removed.
8420 unification of code in functions tempfilename() and tempfile():
8421 function tempnam() is defined in Visual Studio 6.0 and .NET
8423 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8425 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8426 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8427 - removed compiler command line option /WX: Treats all warnings as errors
8428 - update a list of source files, included into the project
8430 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8431 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8432 changed project type to Generic Project so that can be correcly converted to VS.NET project
8434 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8436 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8438 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8440 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8441 added return 0 statements after assert() to make compiler happy
8443 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8444 added newline in the def file to keep MSC compiler satisfied
8446 * sdcc/src/z80/gen.c:
8447 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8448 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8449 - solved MSC error in function aopDump()
8451 * sdcc_vc.h: define PREFIX as "\\sdcc"
8453 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8454 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

8457 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
8458 - Rewrote the register banking algorithm.
8459 - Added pCode live-range analysis to registers (for now, only non-used and
8460 singly-used registers optimized away)
8462 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
8464 * 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.

8493 2002-03-28 Johan Knol <johan AT balder>
8495 * src/SDCCval.c: fixed bug #532436
8497 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8499 Added "char *Processor" field to the port structure.
8502 Added -p option. Allows port dependent processor to be specified.
8505 Initialized the new field char *Processor field to NULL in all ports
8508 Compiler generated registers for interrupt context saving
8509 were not getting allocated.
8511 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8514 Fixed left shift. Will promote the left side of a left shift
8515 if a) left shifting more than size of operand or b) when assigned
8516 to something size > size of left side
8518 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8520 tons of changes. Register allocation has been
8521 rewritten. Added customization for the various PICs. Flow
8522 analysis is restructured. ...

8626 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
8628 * sdcc/src/SDCCloop.c:
8629 Previous fix was not good. basic blocks that have "break" or "return" are
8630 not really partof a loop , but live ranges used in these blocks should
8631 be live thru the entire loop, so set partOfLoop but don't add them to
8634 2002-02-21 <johan AT FRIJA>
8636 * src/SDCCcse.c: fixed bug #514308
8638 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
8641 Fixed BUG #519583. If a conditional block ended in a return/break
8642 statement inside a loop, it was not being considered part of the loop.
8644 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
8646 2002-02-10 Karl Bongers <karl AT turbobit.com>
8649 Fixed up SDCDB debugger somewhat. Updated debugger/README
8650 with lots of comments and notes.
8652 * device/examples/test2.c:
8653 Fix bug, "red" variable not being initialized(compiler complained).
8655 * device/examples/Makefile, examples/test3.c:

8657 for use as a multiple module SDCDB test case.
8659 * sim/ucsim/cmd.src/cmdset.cc:
8660 Took out debug printfs in ucsim "next" command.
8663 Karl and Johan start ucsim XA support. Most dissassembly working,
8664 about 75% emulation done(plenty of work remaining).
8666 * sim/ucsim/z80.src:
8667 Add Z80 support to ucsim, add test-ucz80 regression test,
8668 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.

8704 set preprocessor defines (depending on options)
8706 * src/SDCCicode.c, src/SDCCicode.h:
8707 changes made to handle multiple sends & receives
8710 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
