873 where not placed in the same memory bank,
874 * device/lib/pic16/libsdcc/char/: various modifications to improve
876 * doc/sdccman.lyx: some reorganization of the PIC16 part, added many
877 information on the new functions of the c library and more...
879 2005-03-28 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
881 * src/SDCCBBlock.c (iCodeBreakDown): fixed bug #1170212
883 2005-03-26 Raphael Neider <rneider AT web.de>
885 * src/pic16/gen.c (genSkipc): fixed semantics (execute branch
886 if condition == CARRY)
887 * (genCmp): adapted to new genSkipc semantics
888 * src/pic16/genutils.c (pic6_genCmp_special): removed side effect
889 on rIfx (genCmp was broken)
891 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
893 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
894 * src/z80/main.c (_keywords[]),
895 * src/SDCCglobal.h (struct options),
897 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
898 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
899 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
900 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
901 always available in leading double underscore form. The C99 support is
902 mostly missing, but it's a start.
903 * support/regression/tests/bug-227710.c: fixed nonconforming use of
904 reserved identifier "__data".
906 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

952 2005-03-20 Borut Razem <borut.razem AT siol.net>
954 * support/scripts/inc2h.pl: WIN32 port
956 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
958 * device/lib/makefile.in: added abs.c and labs.c
960 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
962 * device/include/stdint.h: added
963 * device/lib/abs.c: added

980 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
982 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
984 * device/lib/printf_large.c: removed inline assembly for portability and
985 readability. Use printf_fast if speed or size are more important.
986 * src/pic16/gen.c: removed conditions around use of DEBUGpc
987 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
989 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
991 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
992 prevent compiler warning
994 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
996 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
997 moved to level 0 and declared as static. Also they are explicit
998 placed in access bank. This was necessery because some times they
999 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1000 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1001 optimizations. Currently only compare to unsigned char is implemented,
1002 * src/pic16/gen.c: added fReturnIdx array,
1003 * (struct resolvedIfx) is moved to gen.h and made public,
1004 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1005 * (aopForSym): added an optimization to directly store in stack of
1006 the operand of a SEND iCode,
1007 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1008 but as registers instead (AOP_REG) using the fReturnIdx array,
1009 * (pic16_freeAsmop): remove the freed register from the
1010 _G.sregsAlloc field,
1011 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1012 a compare of 'WREG',
1013 * (pic16_popGetTempRegCond): changed function prototype, now
1014 function takes also a bitVector argument v which holds the current
1015 set of registers that are allocated for stack access by aopForSym,
1016 registers allocated in aopForSym for accessing stack symbols are not
1017 any more part of the functions usedRegs field,
1018 * (genCall): some times aopOp is called for a stack variable to be
1019 send, aopForSym might perform the push, if this is true make sure
1020 that genCall doesn't push the variable twice by testing _G.resDirect,
1021 * (genFunction): changed testing for unspecified interrupt number
1022 from 256 to INTNO_UNSPEC,
1023 * modified selection scheme of frame pointer generation. Previously
1024 if function did use local registers a frame pointer was generated,
1025 now a frame pointer is generated only if function has arguments
1026 (that need PLUSW2 register access), or has stack arguments, or the
1027 compiler is not instructed to omit the frame pointer,
1028 * (genEndFunction): before restoring local registers that were saved
1029 in the function preamble, also restore the registers that *might*
1030 have been allocated for stack access,
1031 * (genRet): removed some old comments,
1032 * (genCmp, the active (RN's) version): added a call to the
1033 pic16_genCmp_special function to perform the compare with a more
1034 robust and optimized way,
1035 * (genInline): a feature has been added in inline code generation,
1036 which allows a wildcard variable substitution when writing inline
1037 assembly. Code is incomplete and experimental therefore undocumented,
1038 * (genCast): changed order of aopOp for result and right to allow
1039 aopForSym to directly load the result if possible,
1040 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1041 perform an optimized compare on some selected special occasions,
1042 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1043 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1044 generate an IVT any more,
1045 * src/pic16/main.c (pic16_optionsTable): added command line option
1047 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1048 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1050 * src/pic16/NOTES: Raphael Neider added in list of active developers
1051 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1052 jumptable_end to prevent bug #,
1053 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1054 inCond and outCond fields,
1055 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1056 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1057 turn off register spilling,
1058 * (packRegsForOneUse): synced with other ports' versions although it
1059 is not used currently,
1060 * (pic16_packRegisters): added an optimization while reading
1061 structure bitfields, some registers may be saved (malloc code is
1062 decreased by 80 bytes)
1064 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1066 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1067 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1068 this can be optimized more?
1070 2005-03-10 Raphael Neider <rneider AT web.de>
1072 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1073 genNearPointerGet): (hopefully) fixed access to bitfields via
1074 pointers (p->bitN = x; and x = p->bitN; failed)
1076 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

1263 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
1264 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
1265 this might fix SIGSEGVs on MinGW...
1266 * src/SDCCopt.c (killDeadCode): restored original behaviour
1267 (volatile operands might get thrown away though)
1269 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

1309 macro STACK_MODEL_{SMALL/LARGE} when compiling and assembling to
1310 reflect stack model used,
1311 * src/pic16/ralloc.c (pic16_allocDirReg): when operand is allocated
1312 on stack return NULL,

4792 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4794 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4795 loaded with the linker search paths (-L arguments) and the libraries
4796 to be linked with the current source (-l arguments). Changes
4797 currently will affect only the pic16 port.
4798 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4799 include path the port specific paths and port specific libraries,
4800 * gplink command now contains the $3 argument,
4801 * src/pic16/device.h,
4802 * src/pic16/device.c,: structure PIC_device is made public and
4803 renamed to PIC16_device, the same for variable Pics which is renamed

4818 Documenting changes from previous commits.
4819 * configure.in (version 1.56),
4820 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4821 when generating output files to configure the pic16 library,
4822 but now I've commented it out, since gputils aren't installed in the
4823 SF compile farm, so library won't compile
4825 * device/lib/Makefile.in (version 1.56): initially I've added in
4826 target 'all' the prerequestive 'model-pic16' so it compiled the
4827 pic16 library, but now I've commented it out for the same reasons
4829 * added targets 'model-pic16' and 'objects-pic16' to compile the
4831 * added target 'port-specific-objects-pic16' to handle the
4832 generated libraries and copy them into the build/ directory
4833 * added target 'clean-intermediate-pic16' to clean intermediate
4834 files into pic16 directory
4835 * in target 'installdirs' added line to create directory pic16 in
4836 the installation path
4838 * device/include/Makefile.in (version 1.11): in target 'install'
4839 added lines to copy all header files to installation path,
4840 * in target 'installdirs' added line create directory for pic16
4841 headers in the installation path
4843 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

4854 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4856 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4857 option so that it actually works. Made it specific to the z80, since
4858 the gbz80 doesn't have these kinds of I/O ports.
4860 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4862 * device/include/z180.h,

4928 all over. Telling LaTeX to be less strict with word spacing
4929 to better keep the right margin. Changed some notes about
4930 maintainance of the ports in section 3.2.1 - is it OK like this?
4932 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

4972 * src/pic16/peeph.def: all peepholes with movff are commented out,
4973 because there is a problem in the pcode peep optimizer,
4974 * src/pic16/ralloc.c: the register allocator can now reuse local

5067 include information about variables allocated to the overlay
5070 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5072 * as/mcs51/lkmain.c: Help about -Y option

5084 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5086 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5087 (default behaviour).
5089 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5091 A python script to validate compiler diagnostic messages. It can be
5092 used to verify that sdcc complains about bad c source code and
5093 gives a good location of the error.
5094 * support/valdiag/Makefile,
5095 * support/valdiag/valdiag.py,
5096 * support/valdiag/tests/*
5098 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5100 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

5111 * src/common.h: added ifndef/define/endif macros
5112 around the header file.
5113 Bug reported from Jesus Calvino-Fraga
5115 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5117 * sdcc.spec: updated
5118 * device/include/Makefile.in: don't install CVS directories
5119 * device/lib/Makefile.in: added removal of CVS directories after install
5120 * doc/Makefile: fixed install, added local_icons
5121 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5122 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5123 * src/ds390/gen.c (genRightShift): fixed bug #870788
5124 * src/SDCCast.c (decorateType): fixed bug #870781
5126 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5128 PIC16 port related changes:
5129 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5130 added variable stackPos,
5132 * gen.c: genCall, assignResultValue: added support for
5133 pushing/retrieving function parameters to/from stack,
5134 genFunction,genEndFunction: setup stack frame for the
5136 genAddrOf: will be changed according to bug 863624
5138 * added files genutils.c and genutils.h which contain gen*
5139 debugged and optimised functions extracted from gen.c
5141 * glue.c: added variable 'externs' which holds extern symbols,
5142 pic16emitRegularMap: is modified to properly handle relocatable
5143 symbols under the new scheme,
5144 pic16createInterruptVect: is modified
5145 pic16printPublics: is modified to emit 'global' assembler directives,
5146 added pic16_printExterns to print extern symbols,
5147 pic16glue: initializes stack/frame pointer in the beginning of
5148 the assembly output. Temporary hack, will be corrected later,
5149 because gplink yet does not support stack and SDCC does not
5150 yet support a type of crt0.o object to create the final binary.
5152 * Removed many lines that contain 8051 legacy code.
5153 * The code is finally placed under a 'code' directive.
5154 * Added port specific options.
5156 * _process_pragma: simplified since now we do not need *special*
5157 include file to define SFR registers. But a separate header
5158 will be needed. This will be developed later.
5159 * _pic16_parseOptions: added, parses port specific options:
5160 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5161 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5162 --preplace-udata-with=
5164 * _pic16_setDefaultOptions: modified to initialize section names,
5165 but hack is temporarly out of order since it needs improvement.
5166 * _pic16_genAssemblerPreamble: configuration words are emitted by
5167 their address instead of their name. This part is incomplete and
5168 supports only the 18Fxx2 devices. Other devices will emit an error
5169 during assembly since they do not contain the same set of config
5171 * _pic16_genIVT: is modified,
5173 * pcode.c: added definitions for some hardware registers that are needed
5175 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5176 All PCI entries are updated. Now LFSR is supported.
5177 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5178 * added pic16_newpCodeOpLit2 to support instructions with
5179 two literal arguments
5180 * pic16_pCode2str: corrected code that emits assembler instructions
5181 with two literal operands and those that have an access bit modifier
5182 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5183 this fixes a bug which caused some labels to be lost, when an
5184 assembler directive was added, i.e. banksel,
5185 * pic16_FixRegisterBanking: improved logic that causes the insertion
5187 * InlineFunction: functions that are called once, are not any more
5188 inlined. This can be a port option in the future,
5190 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5192 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5193 hold the corresponding uninitialized symbols,
5194 * pic16_allocProcessorRegister: registers have explicit marked the
5196 * pic16_allocInternalRegister: registers are explicit marked as
5198 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5199 processing list, so bit registers were lost,
5202 * ralloc.h: added field 'accessBank' and original symbol operand
5203 in register definition,
5204 * removed the field isMapped from register definition,
5206 ** Several functions have been removed from various sources:
5207 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5208 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5209 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5210 pic16_assignRelocatableRegisters
5212 ** others have been introduced:
5213 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5214 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5216 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5218 * support/scripts/inc2h.pl: changed definition of BIT_AT
5219 to emit 'sbit at' instead of 'bit at'. This was a request.
5221 PIC16 port related preliminary changes:
5222 * gen.c: prefixed function popRegFromString with
5223 pic16_ and all references to it corrected
5224 * pcode.c: all pic16_pc_* hardware registers prefixed
5225 with underscore (_),
5226 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5227 * ralloc.c: newReg(): when register is REG_SFR then
5228 set address to rIdx,
5229 pic16_allocProcessorRegister(): marks register wasUsed=0
5230 pic16_writeUsedRegs(): added a call to assign processor
5231 registers via pic16_assignFixedRegisters
5233 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5235 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5236 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5237 variables in unused register banks. Also the SSEG is placed
5238 wherever there is enough space for it, and IDATA can be anywhere
5239 in internal RAM. For now compile using -Wl-Y[stack_size].
5240 The mem file is different for this option as well, since it
5241 makes no sense of talking about DSEG lenght.
5243 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5245 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5246 in certain cases, e.g. when ROM assignment, patch provided
5247 from Albert den Haan.
5249 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6272 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6273 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6274 type for bits was changed. It resulted in bit variables becoming

6292 A few small changes that speed up the peephole optimizer.
6296 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6298 Try to make the peephole optimizer smarter by maintaining
6299 an association between the assembly source code and the
6300 iCodes that originated them. Put this information to use
6301 with a new peephole rule condition "notVolatile" so that
6302 the rules can be aggressive yet still safe.
6307 * src/mcs51/peeph.def
6309 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6313 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6314 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6315 if the left or right operand symbols have the accuse flag set.
6317 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6319 Changed the type of the result of the ! (NOT) operator to char;
6320 previously it returned the same type as the source. This allows
6321 us to eliminate all the genFloatNot functions (all of its target
6322 implementations were very buggy) since !float can use the same

6334 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6335 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6336 during interrupts. Ensure WSAVE is located at a shared bank address.
6337 2. Fixed page selection in some places
6338 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6339 the registers name strings.
6340 4. Fixed "signed / unsigned compare" compiler warnings.
6341 5. The PIC port manages its own allocation of the general purpose
6342 registers, but makes no attempt to reuse them. As a result when
6343 compiling it soon runs out of general purpose registers. Some
6344 additional code was added to the files pcode.c and device.c to walk
6345 through the function call tree and rename the registers so that they
6355 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

6362 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6364 Made bitfield a distinct type from bit so that bitfields
6365 convert as per ANSI C and bits retain their traditional
6366 boolean style behaviour. Implemented bitfield support in
6374 * src/ds390/gen.c: bit v bitfield split
6375 * src/z80/gen.c: New support for bitfields
6376 * support/regression/tests/bitfields.c: reenabled z80,
6379 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

6382 access to xdata mapped I/O devices.
6384 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6386 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6388 Cleaned up genPackBits and genUnpackBits and added two helper
6389 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6390 for literal assignments in genPackBits (thanks to Frieder for
6396 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6398 Fixed bug #748310 (pointer to function type mishandled when the
6399 function name is omitted). Also fixed a SIGSEGV when a function
6400 attribute (reentrant, etc) is used on a non-function or on a
6401 function but misplaced before the parameter list.
6403 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6405 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

6428 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6430 Made the constant following the "interrupt" keyword optional. If
6431 omitted, the function will not automatically be given an entry
6432 in the interrupt vector table (similar to #pragma NOIV, but
6433 less syntacticly kludgy). The interrupt number is also now
6434 range checked. Also fixed a bug in the high order bit example

6455 unsigned, but are signed by default
6456 * src/SDCCval.c (constVal): rearranged
6457 * src/SDCCval.c (valMod): preliminary fix
6458 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6952 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
6954 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
6955 it can be defined with CFLAGS when running configure
6956 * src/SDCCmain.c: fixed compiling + linking with object files
6958 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
6960 * configure.in: configure for pic16 port,
6961 added --disable-pic16-port
6962 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
6963 * src/SDCCmain.c: linkOptions is changed to set *,
6964 added if/endif conditional macros to remove options help
6965 messages from optionsTable when a port is not configured, added
6966 support for the PIc16 port in the ports table, when executing
6967 the compiler with no port specified on command line, a default
6968 port is selected with the new macro DEFAULT_PORT which is
6969 defined in port.h, in setDefaultOptions() linkOptions is removed
6970 from initialization assignment, since now it is a set,
6971 parseCmdLine uses setParseWithComma for linkOptions, in
6972 linkEdit() linkOptions are accessed with new function indexSet()
6973 which returns the i'th item of a set variable. See SDCCset.c, in
6974 linkEdit() when calling buildCmdLine(), added linkOptions as
6975 last argument. Now users can pass arguments to gplink via the
6976 -Wl option, main() uses pic16glue() to glue up pic16 programs
6977 * src/SDCCpeeph.c: various changes to support pic16

6988 * src/pic16/glue.c: commented out some error producing lines
6989 * src/pic16/main.c: __config directives are commented out to stop
6990 gpasm complaining and test the linkage with gplink, _linkCmd and
6991 _asmCmd changed to be more gplink and gpasm friendly
6992 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6993 produced an error when parsed, peep rule 12 is added to utilize
6994 movff, but it is commented out since the pCode does not support
6995 yet a command with 2 address arguments
6997 2003-05-18 <johan AT balder>
6999 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7026 2003-05-11 Borut Razem <borut.razem AT siol.net>
7028 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7029 the path of bin directory, so that PATH is the only env. variable, which has to be set

8034 * src/SDCCicode.c: fixed array add
8036 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
8037 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
8038 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
8040 2003-01-04 <johan AT balder>
8042 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8044 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8045 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
8047 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
8048 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

8055 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
8057 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8058 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8060 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8062 * in \sdcc\as\mcs51\ changed these files in order to create an
8063 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8064 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8065 following files to include the previous two files: aslink.dsp,
8066 Makefile.aslink, Makefile.bcc, and Makefile.in.
8068 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8069 .adb instead of .cdb
8071 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8073 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8074 value from option --iram-size.
8076 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8078 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8081 2002-09-18 <wiml AT hhhh.org>
8083 * SDCClrange.h: exposed setFromRange() and setToRange()
8084 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8085 packRegsForAccUse() (bug 542397)
8086 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8087 multiple times and emitting the fetch operations more than once
8088 added aopGetUsesAcc() function to allow binary operators to
8089 fetch their operands in the correct order; made genMinus() emit
8090 compact code for X = LITERAL - Y
8092 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8093 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8094 sprintf() in line 1267.
8096 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8097 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8100 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8101 Changes to aslink (All the changes are marked with 'JCF'):
8103 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8106 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8107 area BSEG. Also moves, if possible, the DATA area down into the internal
8108 ram so more space is available.
8110 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8113 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8114 not bytes. Function summary() which creates a memory usage summary
8115 file with extension .mem. Reports of overlaping stack and small stack
8116 size. If the space for the stack is less than 16 bytes aslink trows a
8119 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8120 the 8051. Option 'y' for memory summary output file.
8122 Changes to sdcc (All the changes are marked with 'JCF'):
8124 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8126 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8127 overlaying area for it (uses RegBankUsed[4]).
8129 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8130 bank zero as used by default. By default aslink locates the stack
8131 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8132 the creation of the .mem file. Delegates the allocation of data area
8133 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8134 the begining of the stack area to aslink.
8136 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8137 glue() in SDCCglue.c creates an area for it.
8139 2002-09-03 Borut Razem <borut.razem AT siol.net>
8140 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8141 sdcc/src/pic/glue.c:
8142 introduced atexit() handler for teporay files removal in case of
8143 errors, assertions, ...
8145 2002-08-29 Borut Razem <borut.razem AT siol.net>
8146 * sdcc/support/cpp2/auto-host_vc_in.h:
8147 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8148 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8149 Maybe there is a similar problem with BORLANDC? It should be checked!
8151 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8152 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8153 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8154 was not executed, and the compiler (cl) launched a warning:
8155 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8157 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8158 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8160 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8161 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8163 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8164 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8165 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8166 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8167 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8168 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8169 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8170 - added Release configuration in VS projects
8171 - review of compiler an linker options
8172 - VC .exe files are generated in bin_vc directory, not to interfere
8173 with binaries generated from other projects (cygwin, mingw, bcc ...)
8175 * sdcc/src/yacc.dsp: added
8177 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8178 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8179 and insert the version number definitions from .version
8181 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8183 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8184 added - genarate auto-host.h using auto-host_vc_in.h as template
8187 removed from CVS, generated automatically
8189 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8190 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8192 2002-08-11 Borut Razem <borut.razem AT siol.net>
8193 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8195 2002-08-10 Borut Razem <borut.razem AT siol.net>
8196 * src/SDCCmain.c (main):
8197 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8198 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8199 The consequence was that some temporary files were not removed.
8202 unification of code in functions tempfilename() and tempfile():
8203 function tempnam() is defined in Visual Studio 6.0 and .NET
8205 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8207 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8208 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8209 - removed compiler command line option /WX: Treats all warnings as errors
8210 - update a list of source files, included into the project
8212 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8213 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8214 changed project type to Generic Project so that can be correcly converted to VS.NET project
8216 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8218 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8220 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8222 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8223 added return 0 statements after assert() to make compiler happy
8225 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8226 added newline in the def file to keep MSC compiler satisfied
8228 * sdcc/src/z80/gen.c:
8229 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8230 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8231 - solved MSC error in function aopDump()
8233 * sdcc_vc.h: define PREFIX as "\\sdcc"
8235 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8236 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
8238 2002-06-22 Scott Dattalo <scott AT dattalo.com>
8239 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
8240 - Rewrote the register banking algorithm.
8241 - Added pCode live-range analysis to registers (for now, only non-used and
8242 singly-used registers optimized away)
8244 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
