875 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
876 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
877 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
878 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
879 always available in leading double underscore form. The C99 support is
880 mostly missing, but it's a start.
881 * support/regression/tests/bug-227710.c: fixed nonconforming use of
882 reserved identifier "__data".
884 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

930 2005-03-20 Borut Razem <borut.razem AT siol.net>
932 * support/scripts/inc2h.pl: WIN32 port
934 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>

955 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
957 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
958 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
960 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
962 * device/lib/printf_large.c: removed inline assembly for portability and
963 readability. Use printf_fast if speed or size are more important.
964 * src/pic16/gen.c: removed conditions around use of DEBUGpc
965 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
967 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
969 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
970 prevent compiler warning
972 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
974 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
975 moved to level 0 and declared as static. Also they are explicit
976 placed in access bank. This was necessery because some times they
977 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
978 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
979 optimizations. Currently only compare to unsigned char is implemented,
980 * src/pic16/gen.c: added fReturnIdx array,
981 * (struct resolvedIfx) is moved to gen.h and made public,
982 * (struct _G): added sregsAlloc and sregsAllocSet fields,
983 * (aopForSym): added an optimization to directly store in stack of
984 the operand of a SEND iCode,
985 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
986 but as registers instead (AOP_REG) using the fReturnIdx array,
987 * (pic16_freeAsmop): remove the freed register from the
989 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
991 * (pic16_popGetTempRegCond): changed function prototype, now
992 function takes also a bitVector argument v which holds the current
993 set of registers that are allocated for stack access by aopForSym,
994 registers allocated in aopForSym for accessing stack symbols are not
995 any more part of the functions usedRegs field,
996 * (genCall): some times aopOp is called for a stack variable to be
997 send, aopForSym might perform the push, if this is true make sure
998 that genCall doesn't push the variable twice by testing _G.resDirect,
999 * (genFunction): changed testing for unspecified interrupt number
1000 from 256 to INTNO_UNSPEC,
1001 * modified selection scheme of frame pointer generation. Previously
1002 if function did use local registers a frame pointer was generated,
1003 now a frame pointer is generated only if function has arguments
1004 (that need PLUSW2 register access), or has stack arguments, or the
1005 compiler is not instructed to omit the frame pointer,
1006 * (genEndFunction): before restoring local registers that were saved
1007 in the function preamble, also restore the registers that *might*
1008 have been allocated for stack access,
1009 * (genRet): removed some old comments,
1010 * (genCmp, the active (RN's) version): added a call to the
1011 pic16_genCmp_special function to perform the compare with a more
1012 robust and optimized way,
1013 * (genInline): a feature has been added in inline code generation,
1014 which allows a wildcard variable substitution when writing inline
1015 assembly. Code is incomplete and experimental therefore undocumented,
1016 * (genCast): changed order of aopOp for result and right to allow
1017 aopForSym to directly load the result if possible,
1018 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1019 perform an optimized compare on some selected special occasions,
1020 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1021 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1022 generate an IVT any more,
1023 * src/pic16/main.c (pic16_optionsTable): added command line option
1025 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1026 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1028 * src/pic16/NOTES: Raphael Neider added in list of active developers
1029 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1030 jumptable_end to prevent bug #,
1031 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1032 inCond and outCond fields,
1033 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1034 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1035 turn off register spilling,
1036 * (packRegsForOneUse): synced with other ports' versions although it
1037 is not used currently,
1038 * (pic16_packRegisters): added an optimization while reading
1039 structure bitfields, some registers may be saved (malloc code is
1040 decreased by 80 bytes)
1042 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1044 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1045 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1046 this can be optimized more?
1048 2005-03-10 Raphael Neider <rneider AT web.de>
1050 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1051 genNearPointerGet): (hopefully) fixed access to bitfields via
1052 pointers (p->bitN = x; and x = p->bitN; failed)
1054 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

1242 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
1243 this might fix SIGSEGVs on MinGW...
1244 * src/SDCCopt.c (killDeadCode): restored original behaviour
1245 (volatile operands might get thrown away though)
1247 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

1380 accessing SFRs. Updated all occurences of modification of stack or
1381 frame pointer in gen.c and pcode.c,

1687 generated for switch statements. For now you need to set the
1688 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1689 Now 4 algorithms for mcs51 jumptable generation are used:
1690 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

1722 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1724 * added libc directory. The current version of LibC contains string
1725 functions, ctype functions and macros and some functions of the
1726 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1727 be extensively tested in the future. Standard disclaimer here.
1728 Library is not automatically build yet. But one can build it by
1729 invoking 'make' inside the libc directory.

1739 * (genUminusFloat): fixed for pic16, ported code from mcs51,
1740 * (pic16_storeForReturn): optimized return of 0,
1741 * (genCmp): experimental code for new genCmp which uses PIC18's
1742 special compare&skip instructions. Initial tests fail some times
1743 with variables grater than 1 byte in size, so new code is disabled,
1744 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1746 * (genCast): began a fix to optimize the casting of a bit to another
1747 bit, now assigning a bitfield to another bitfield will fail, sorry,
1748 * src/pic16/main.c: disabled the use of lr-support feature,
1749 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

1752 bits with offset (case PO_GPR_BIT),
1753 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
1755 * (isBankInstruction): modified to return 0 for no banking instruction,

4770 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4772 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4773 loaded with the linker search paths (-L arguments) and the libraries
4774 to be linked with the current source (-l arguments). Changes
4775 currently will affect only the pic16 port.
4776 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4777 include path the port specific paths and port specific libraries,
4778 * gplink command now contains the $3 argument,
4779 * src/pic16/device.h,
4780 * src/pic16/device.c,: structure PIC_device is made public and
4781 renamed to PIC16_device, the same for variable Pics which is renamed

4796 Documenting changes from previous commits.
4797 * configure.in (version 1.56),
4798 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4799 when generating output files to configure the pic16 library,
4800 but now I've commented it out, since gputils aren't installed in the
4801 SF compile farm, so library won't compile
4803 * device/lib/Makefile.in (version 1.56): initially I've added in
4804 target 'all' the prerequestive 'model-pic16' so it compiled the
4805 pic16 library, but now I've commented it out for the same reasons
4807 * added targets 'model-pic16' and 'objects-pic16' to compile the
4809 * added target 'port-specific-objects-pic16' to handle the
4810 generated libraries and copy them into the build/ directory
4811 * added target 'clean-intermediate-pic16' to clean intermediate
4812 files into pic16 directory
4813 * in target 'installdirs' added line to create directory pic16 in
4814 the installation path
4816 * device/include/Makefile.in (version 1.11): in target 'install'
4817 added lines to copy all header files to installation path,
4818 * in target 'installdirs' added line create directory for pic16
4819 headers in the installation path

4835 option so that it actually works. Made it specific to the z80, since
4836 the gbz80 doesn't have these kinds of I/O ports.
4838 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4840 * device/include/z180.h,

4869 weren't marked as being in the access bank,
4871 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4873 Added portion of GNU PIC Library under the directory
4874 device/include/pic16 and device/lib/pic16. These files
4875 contain the declarations of SFRs for the PIC18Fxx2 devices.
4876 The directory is initialized via configure from toplevel.
4878 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

4906 all over. Telling LaTeX to be less strict with word spacing
4907 to better keep the right margin. Changed some notes about
4908 maintainance of the ports in section 3.2.1 - is it OK like this?
4910 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

4948 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
4950 * src/pic16/peeph.def: all peepholes with movff are commented out,
4951 because there is a problem in the pcode peep optimizer,
4952 * src/pic16/ralloc.c: the register allocator can now reuse local

5045 include information about variables allocated to the overlay
5048 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5050 * as/mcs51/lkmain.c: Help about -Y option

5062 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5064 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5065 (default behaviour).
5067 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5069 A python script to validate compiler diagnostic messages. It can be
5070 used to verify that sdcc complains about bad c source code and
5071 gives a good location of the error.
5072 * support/valdiag/Makefile,
5073 * support/valdiag/valdiag.py,
5074 * support/valdiag/tests/*
5076 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5090 around the header file.
5091 Bug reported from Jesus Calvino-Fraga
5093 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5095 * sdcc.spec: updated
5096 * device/include/Makefile.in: don't install CVS directories
5097 * device/lib/Makefile.in: added removal of CVS directories after install
5098 * doc/Makefile: fixed install, added local_icons
5099 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5100 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5101 * src/ds390/gen.c (genRightShift): fixed bug #870788
5102 * src/SDCCast.c (decorateType): fixed bug #870781
5104 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5106 PIC16 port related changes:
5107 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5108 added variable stackPos,
5110 * gen.c: genCall, assignResultValue: added support for
5111 pushing/retrieving function parameters to/from stack,
5112 genFunction,genEndFunction: setup stack frame for the
5114 genAddrOf: will be changed according to bug 863624
5116 * added files genutils.c and genutils.h which contain gen*
5117 debugged and optimised functions extracted from gen.c
5119 * glue.c: added variable 'externs' which holds extern symbols,
5120 pic16emitRegularMap: is modified to properly handle relocatable
5121 symbols under the new scheme,
5122 pic16createInterruptVect: is modified
5123 pic16printPublics: is modified to emit 'global' assembler directives,
5124 added pic16_printExterns to print extern symbols,
5125 pic16glue: initializes stack/frame pointer in the beginning of
5126 the assembly output. Temporary hack, will be corrected later,
5127 because gplink yet does not support stack and SDCC does not
5128 yet support a type of crt0.o object to create the final binary.
5130 * Removed many lines that contain 8051 legacy code.
5131 * The code is finally placed under a 'code' directive.
5132 * Added port specific options.
5134 * _process_pragma: simplified since now we do not need *special*
5135 include file to define SFR registers. But a separate header
5136 will be needed. This will be developed later.
5137 * _pic16_parseOptions: added, parses port specific options:
5138 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5139 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5140 --preplace-udata-with=
5142 * _pic16_setDefaultOptions: modified to initialize section names,
5143 but hack is temporarly out of order since it needs improvement.
5144 * _pic16_genAssemblerPreamble: configuration words are emitted by
5145 their address instead of their name. This part is incomplete and
5146 supports only the 18Fxx2 devices. Other devices will emit an error
5147 during assembly since they do not contain the same set of config
5149 * _pic16_genIVT: is modified,
5151 * pcode.c: added definitions for some hardware registers that are needed
5153 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5154 All PCI entries are updated. Now LFSR is supported.
5155 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5156 * added pic16_newpCodeOpLit2 to support instructions with
5157 two literal arguments
5158 * pic16_pCode2str: corrected code that emits assembler instructions
5159 with two literal operands and those that have an access bit modifier
5160 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5161 this fixes a bug which caused some labels to be lost, when an
5162 assembler directive was added, i.e. banksel,
5163 * pic16_FixRegisterBanking: improved logic that causes the insertion
5165 * InlineFunction: functions that are called once, are not any more
5166 inlined. This can be a port option in the future,
5168 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5170 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5171 hold the corresponding uninitialized symbols,
5172 * pic16_allocProcessorRegister: registers have explicit marked the
5174 * pic16_allocInternalRegister: registers are explicit marked as
5176 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5177 processing list, so bit registers were lost,
5180 * ralloc.h: added field 'accessBank' and original symbol operand
5181 in register definition,
5182 * removed the field isMapped from register definition,
5184 ** Several functions have been removed from various sources:
5185 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5186 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5187 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5188 pic16_assignRelocatableRegisters
5190 ** others have been introduced:
5191 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5192 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5194 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5196 * support/scripts/inc2h.pl: changed definition of BIT_AT
5197 to emit 'sbit at' instead of 'bit at'. This was a request.
5199 PIC16 port related preliminary changes:
5200 * gen.c: prefixed function popRegFromString with
5201 pic16_ and all references to it corrected
5202 * pcode.c: all pic16_pc_* hardware registers prefixed
5203 with underscore (_),
5204 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5205 * ralloc.c: newReg(): when register is REG_SFR then
5206 set address to rIdx,
5207 pic16_allocProcessorRegister(): marks register wasUsed=0
5208 pic16_writeUsedRegs(): added a call to assign processor
5209 registers via pic16_assignFixedRegisters
5211 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5213 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5214 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5215 variables in unused register banks. Also the SSEG is placed
5216 wherever there is enough space for it, and IDATA can be anywhere
5217 in internal RAM. For now compile using -Wl-Y[stack_size].
5218 The mem file is different for this option as well, since it
5219 makes no sense of talking about DSEG lenght.
5221 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5223 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5224 in certain cases, e.g. when ROM assignment, patch provided
5225 from Albert den Haan.
5227 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5373 without the non-interrupt code having to disable interrupts)
5375 2003-12-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5377 * src/SDCCicode.c (geniCodeAdd),

5470 it breaks with bitfields, extern declarations, and gcse analysis.
5471 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
5472 could be assigned through a pointer, so don't complain.

6250 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6251 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6252 type for bits was changed. It resulted in bit variables becoming
6253 global, which is not permitted in PIC 14 assembly output.

6270 A few small changes that speed up the peephole optimizer.
6274 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6276 Try to make the peephole optimizer smarter by maintaining
6277 an association between the assembly source code and the
6278 iCodes that originated them. Put this information to use
6279 with a new peephole rule condition "notVolatile" so that
6280 the rules can be aggressive yet still safe.
6285 * src/mcs51/peeph.def
6287 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6291 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6292 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6293 if the left or right operand symbols have the accuse flag set.
6295 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6297 Changed the type of the result of the ! (NOT) operator to char;
6298 previously it returned the same type as the source. This allows
6299 us to eliminate all the genFloatNot functions (all of its target
6300 implementations were very buggy) since !float can use the same
6303 * src/SDCCicode.c (ast2iCode): ! returns char

6312 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6313 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6314 during interrupts. Ensure WSAVE is located at a shared bank address.
6315 2. Fixed page selection in some places
6316 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6317 the registers name strings.
6318 4. Fixed "signed / unsigned compare" compiler warnings.
6319 5. The PIC port manages its own allocation of the general purpose
6320 registers, but makes no attempt to reuse them. As a result when
6321 compiling it soon runs out of general purpose registers. Some
6322 additional code was added to the files pcode.c and device.c to walk
6323 through the function call tree and rename the registers so that they
6333 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6334 genPlus() & genMinus() when the result is the same as left or right
6336 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6340 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6342 Made bitfield a distinct type from bit so that bitfields
6343 convert as per ANSI C and bits retain their traditional
6344 boolean style behaviour. Implemented bitfield support in
6352 * src/ds390/gen.c: bit v bitfield split
6353 * src/z80/gen.c: New support for bitfields
6354 * support/regression/tests/bitfields.c: reenabled z80,
6357 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6359 Rules 246.x, 247.x relate to bitfields, the others speed up
6360 access to xdata mapped I/O devices.
6362 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6364 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6366 Cleaned up genPackBits and genUnpackBits and added two helper
6367 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6368 for literal assignments in genPackBits (thanks to Frieder for
6374 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6376 Fixed bug #748310 (pointer to function type mishandled when the
6377 function name is omitted). Also fixed a SIGSEGV when a function
6378 attribute (reentrant, etc) is used on a non-function or on a

6409 omitted, the function will not automatically be given an entry
6410 in the interrupt vector table (similar to #pragma NOIV, but

6948 from initialization assignment, since now it is a set,
6949 parseCmdLine uses setParseWithComma for linkOptions, in
6950 linkEdit() linkOptions are accessed with new function indexSet()
6951 which returns the i'th item of a set variable. See SDCCset.c, in
6952 linkEdit() when calling buildCmdLine(), added linkOptions as
6953 last argument. Now users can pass arguments to gplink via the
6954 -Wl option, main() uses pic16glue() to glue up pic16 programs

6968 gpasm complaining and test the linkage with gplink, _linkCmd and
6969 _asmCmd changed to be more gplink and gpasm friendly
6970 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6971 produced an error when parsed, peep rule 12 is added to utilize
6972 movff, but it is commented out since the pCode does not support
6973 yet a command with 2 address arguments

7995 2003-01-07 <johan AT balder>
7997 * src/SDCCast.c (decorateType): fixed bug #600035

8012 * src/SDCCicode.c: fixed array add
8014 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
8015 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
8016 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
8018 2003-01-04 <johan AT balder>
8020 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8022 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8023 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
8025 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
8026 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

8032 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
8033 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
8035 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8036 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8038 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8040 * in \sdcc\as\mcs51\ changed these files in order to create an
8041 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8042 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8043 following files to include the previous two files: aslink.dsp,
8044 Makefile.aslink, Makefile.bcc, and Makefile.in.
8046 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8047 .adb instead of .cdb
8049 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8051 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8052 value from option --iram-size.
8054 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8056 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8059 2002-09-18 <wiml AT hhhh.org>
8061 * SDCClrange.h: exposed setFromRange() and setToRange()
8062 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8063 packRegsForAccUse() (bug 542397)
8064 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8065 multiple times and emitting the fetch operations more than once
8066 added aopGetUsesAcc() function to allow binary operators to
8067 fetch their operands in the correct order; made genMinus() emit
8068 compact code for X = LITERAL - Y
8070 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8071 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8072 sprintf() in line 1267.
8074 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8075 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8078 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8079 Changes to aslink (All the changes are marked with 'JCF'):
8081 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8084 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8085 area BSEG. Also moves, if possible, the DATA area down into the internal
8086 ram so more space is available.
8088 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8091 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8092 not bytes. Function summary() which creates a memory usage summary
8093 file with extension .mem. Reports of overlaping stack and small stack
8094 size. If the space for the stack is less than 16 bytes aslink trows a
8097 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8098 the 8051. Option 'y' for memory summary output file.
8100 Changes to sdcc (All the changes are marked with 'JCF'):
8102 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8104 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8105 overlaying area for it (uses RegBankUsed[4]).
8107 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8108 bank zero as used by default. By default aslink locates the stack
8109 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8110 the creation of the .mem file. Delegates the allocation of data area
8111 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8112 the begining of the stack area to aslink.
8114 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8115 glue() in SDCCglue.c creates an area for it.
8117 2002-09-03 Borut Razem <borut.razem AT siol.net>
8118 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8119 sdcc/src/pic/glue.c:
8120 introduced atexit() handler for teporay files removal in case of
8121 errors, assertions, ...
8123 2002-08-29 Borut Razem <borut.razem AT siol.net>
8124 * sdcc/support/cpp2/auto-host_vc_in.h:
8125 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8126 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8127 Maybe there is a similar problem with BORLANDC? It should be checked!
8129 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8130 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8131 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8132 was not executed, and the compiler (cl) launched a warning:
8133 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8135 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8136 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8138 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8139 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8141 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8142 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8143 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8144 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8145 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8146 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8147 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8148 - added Release configuration in VS projects
8149 - review of compiler an linker options
8150 - VC .exe files are generated in bin_vc directory, not to interfere
8151 with binaries generated from other projects (cygwin, mingw, bcc ...)
8153 * sdcc/src/yacc.dsp: added
8155 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8156 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8157 and insert the version number definitions from .version
8159 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8161 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8162 added - genarate auto-host.h using auto-host_vc_in.h as template
8165 removed from CVS, generated automatically
8167 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8168 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8170 2002-08-11 Borut Razem <borut.razem AT siol.net>
8171 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8173 2002-08-10 Borut Razem <borut.razem AT siol.net>
8174 * src/SDCCmain.c (main):
8175 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8176 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8177 The consequence was that some temporary files were not removed.
8180 unification of code in functions tempfilename() and tempfile():
8181 function tempnam() is defined in Visual Studio 6.0 and .NET
8183 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8185 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8186 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8187 - removed compiler command line option /WX: Treats all warnings as errors
8188 - update a list of source files, included into the project
8190 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8191 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8192 changed project type to Generic Project so that can be correcly converted to VS.NET project
8194 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8196 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8198 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8200 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8201 added return 0 statements after assert() to make compiler happy
8203 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8204 added newline in the def file to keep MSC compiler satisfied
8206 * sdcc/src/z80/gen.c:
8207 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8208 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8209 - solved MSC error in function aopDump()
8211 * sdcc_vc.h: define PREFIX as "\\sdcc"
8213 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8214 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
8216 2002-06-22 Scott Dattalo <scott AT dattalo.com>
8217 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
8218 - Rewrote the register banking algorithm.
8219 - Added pCode live-range analysis to registers (for now, only non-used and
8220 singly-used registers optimized away)
8222 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
8224 * 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.
8226 2002-05-10 Scott Dattalo <scott AT dattalo.com>
8227 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
8229 2002-04-22 Michael Hope <michaelh AT vroom>

8245 * src/z80/peeph.def: Added transpose redundent load rule.
8247 * src/z80/main.c: Added force callee saves for jaune.
8249 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
8251 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
8253 2002-03-28 Johan Knol <johan AT balder>
8255 * src/SDCCval.c: fixed bug #532436
8257 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8259 Added "char *Processor" field to the port structure.
