877 where not placed in the same memory bank,
878 * device/lib/pic16/libsdcc/char/: various modifications to improve
880 * doc/sdccman.lyx: some reorganization of the PIC16 part, added many

893 on rIfx (genCmp was broken)
895 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
897 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
898 * src/z80/main.c (_keywords[]),
899 * src/SDCCglobal.h (struct options),
901 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
902 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
903 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
904 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
905 always available in leading double underscore form. The C99 support is
906 mostly missing, but it's a start.
907 * support/regression/tests/bug-227710.c: fixed nonconforming use of
908 reserved identifier "__data".
910 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

956 2005-03-20 Borut Razem <borut.razem AT siol.net>
958 * support/scripts/inc2h.pl: WIN32 port

986 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
988 * device/lib/printf_large.c: removed inline assembly for portability and
989 readability. Use printf_fast if speed or size are more important.
990 * src/pic16/gen.c: removed conditions around use of DEBUGpc
991 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
993 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
995 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
996 prevent compiler warning
998 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1000 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1001 moved to level 0 and declared as static. Also they are explicit
1002 placed in access bank. This was necessery because some times they
1003 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1004 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1005 optimizations. Currently only compare to unsigned char is implemented,
1006 * src/pic16/gen.c: added fReturnIdx array,
1007 * (struct resolvedIfx) is moved to gen.h and made public,
1008 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1009 * (aopForSym): added an optimization to directly store in stack of
1010 the operand of a SEND iCode,
1011 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1012 but as registers instead (AOP_REG) using the fReturnIdx array,
1013 * (pic16_freeAsmop): remove the freed register from the
1014 _G.sregsAlloc field,
1015 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1016 a compare of 'WREG',
1017 * (pic16_popGetTempRegCond): changed function prototype, now
1018 function takes also a bitVector argument v which holds the current
1019 set of registers that are allocated for stack access by aopForSym,
1020 registers allocated in aopForSym for accessing stack symbols are not
1021 any more part of the functions usedRegs field,
1022 * (genCall): some times aopOp is called for a stack variable to be
1023 send, aopForSym might perform the push, if this is true make sure
1024 that genCall doesn't push the variable twice by testing _G.resDirect,
1025 * (genFunction): changed testing for unspecified interrupt number
1026 from 256 to INTNO_UNSPEC,
1027 * modified selection scheme of frame pointer generation. Previously
1028 if function did use local registers a frame pointer was generated,
1029 now a frame pointer is generated only if function has arguments
1030 (that need PLUSW2 register access), or has stack arguments, or the
1031 compiler is not instructed to omit the frame pointer,
1032 * (genEndFunction): before restoring local registers that were saved
1033 in the function preamble, also restore the registers that *might*
1034 have been allocated for stack access,
1035 * (genRet): removed some old comments,
1036 * (genCmp, the active (RN's) version): added a call to the
1037 pic16_genCmp_special function to perform the compare with a more
1038 robust and optimized way,
1039 * (genInline): a feature has been added in inline code generation,
1040 which allows a wildcard variable substitution when writing inline
1041 assembly. Code is incomplete and experimental therefore undocumented,
1042 * (genCast): changed order of aopOp for result and right to allow
1043 aopForSym to directly load the result if possible,
1044 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1045 perform an optimized compare on some selected special occasions,
1046 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1047 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1048 generate an IVT any more,
1049 * src/pic16/main.c (pic16_optionsTable): added command line option
1051 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1052 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1054 * src/pic16/NOTES: Raphael Neider added in list of active developers
1055 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1056 jumptable_end to prevent bug #,
1057 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1058 inCond and outCond fields,
1059 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1060 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1061 turn off register spilling,
1062 * (packRegsForOneUse): synced with other ports' versions although it
1063 is not used currently,
1064 * (pic16_packRegisters): added an optimization while reading
1065 structure bitfields, some registers may be saved (malloc code is
1066 decreased by 80 bytes)
1068 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1070 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1071 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1072 this can be optimized more?
1074 2005-03-10 Raphael Neider <rneider AT web.de>
1076 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1077 genNearPointerGet): (hopefully) fixed access to bitfields via
1078 pointers (p->bitN = x; and x = p->bitN; failed)
1080 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

1267 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
1268 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
1269 this might fix SIGSEGVs on MinGW...
1270 * src/SDCCopt.c (killDeadCode): restored original behaviour
1271 (volatile operands might get thrown away though)
1273 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

4796 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4798 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4799 loaded with the linker search paths (-L arguments) and the libraries
4800 to be linked with the current source (-l arguments). Changes
4801 currently will affect only the pic16 port.
4802 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4803 include path the port specific paths and port specific libraries,
4804 * gplink command now contains the $3 argument,
4805 * src/pic16/device.h,
4806 * src/pic16/device.c,: structure PIC_device is made public and
4807 renamed to PIC16_device, the same for variable Pics which is renamed

4822 Documenting changes from previous commits.
4823 * configure.in (version 1.56),
4824 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4825 when generating output files to configure the pic16 library,
4826 but now I've commented it out, since gputils aren't installed in the
4827 SF compile farm, so library won't compile
4829 * device/lib/Makefile.in (version 1.56): initially I've added in
4830 target 'all' the prerequestive 'model-pic16' so it compiled the
4831 pic16 library, but now I've commented it out for the same reasons
4833 * added targets 'model-pic16' and 'objects-pic16' to compile the
4835 * added target 'port-specific-objects-pic16' to handle the
4836 generated libraries and copy them into the build/ directory
4837 * added target 'clean-intermediate-pic16' to clean intermediate
4838 files into pic16 directory
4839 * in target 'installdirs' added line to create directory pic16 in
4840 the installation path
4842 * device/include/Makefile.in (version 1.11): in target 'install'
4843 added lines to copy all header files to installation path,
4844 * in target 'installdirs' added line create directory for pic16
4845 headers in the installation path
4847 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

4858 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4860 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4861 option so that it actually works. Made it specific to the z80, since
4862 the gbz80 doesn't have these kinds of I/O ports.

4932 all over. Telling LaTeX to be less strict with word spacing
4933 to better keep the right margin. Changed some notes about
4934 maintainance of the ports in section 3.2.1 - is it OK like this?
4936 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

4974 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
4976 * src/pic16/peeph.def: all peepholes with movff are commented out,
4977 because there is a problem in the pcode peep optimizer,
4978 * src/pic16/ralloc.c: the register allocator can now reuse local

5071 include information about variables allocated to the overlay
5074 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5076 * as/mcs51/lkmain.c: Help about -Y option

5088 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5090 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5091 (default behaviour).
5093 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5095 A python script to validate compiler diagnostic messages. It can be
5096 used to verify that sdcc complains about bad c source code and
5097 gives a good location of the error.
5098 * support/valdiag/Makefile,
5099 * support/valdiag/valdiag.py,
5100 * support/valdiag/tests/*
5102 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5115 * src/common.h: added ifndef/define/endif macros
5116 around the header file.
5117 Bug reported from Jesus Calvino-Fraga
5119 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5121 * sdcc.spec: updated
5122 * device/include/Makefile.in: don't install CVS directories
5123 * device/lib/Makefile.in: added removal of CVS directories after install
5124 * doc/Makefile: fixed install, added local_icons
5125 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5126 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5127 * src/ds390/gen.c (genRightShift): fixed bug #870788
5128 * src/SDCCast.c (decorateType): fixed bug #870781
5130 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5132 PIC16 port related changes:
5133 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5134 added variable stackPos,
5136 * gen.c: genCall, assignResultValue: added support for
5137 pushing/retrieving function parameters to/from stack,
5138 genFunction,genEndFunction: setup stack frame for the
5140 genAddrOf: will be changed according to bug 863624
5142 * added files genutils.c and genutils.h which contain gen*
5143 debugged and optimised functions extracted from gen.c
5145 * glue.c: added variable 'externs' which holds extern symbols,
5146 pic16emitRegularMap: is modified to properly handle relocatable
5147 symbols under the new scheme,
5148 pic16createInterruptVect: is modified
5149 pic16printPublics: is modified to emit 'global' assembler directives,
5150 added pic16_printExterns to print extern symbols,
5151 pic16glue: initializes stack/frame pointer in the beginning of
5152 the assembly output. Temporary hack, will be corrected later,
5153 because gplink yet does not support stack and SDCC does not
5154 yet support a type of crt0.o object to create the final binary.
5156 * Removed many lines that contain 8051 legacy code.
5157 * The code is finally placed under a 'code' directive.
5158 * Added port specific options.
5160 * _process_pragma: simplified since now we do not need *special*
5161 include file to define SFR registers. But a separate header
5162 will be needed. This will be developed later.
5163 * _pic16_parseOptions: added, parses port specific options:
5164 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5165 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5166 --preplace-udata-with=
5168 * _pic16_setDefaultOptions: modified to initialize section names,
5169 but hack is temporarly out of order since it needs improvement.
5170 * _pic16_genAssemblerPreamble: configuration words are emitted by
5171 their address instead of their name. This part is incomplete and
5172 supports only the 18Fxx2 devices. Other devices will emit an error
5173 during assembly since they do not contain the same set of config
5175 * _pic16_genIVT: is modified,
5177 * pcode.c: added definitions for some hardware registers that are needed
5179 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5180 All PCI entries are updated. Now LFSR is supported.
5181 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5182 * added pic16_newpCodeOpLit2 to support instructions with
5183 two literal arguments
5184 * pic16_pCode2str: corrected code that emits assembler instructions
5185 with two literal operands and those that have an access bit modifier
5186 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5187 this fixes a bug which caused some labels to be lost, when an
5188 assembler directive was added, i.e. banksel,
5189 * pic16_FixRegisterBanking: improved logic that causes the insertion
5191 * InlineFunction: functions that are called once, are not any more
5192 inlined. This can be a port option in the future,
5194 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5196 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5197 hold the corresponding uninitialized symbols,
5198 * pic16_allocProcessorRegister: registers have explicit marked the
5200 * pic16_allocInternalRegister: registers are explicit marked as
5202 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5203 processing list, so bit registers were lost,
5206 * ralloc.h: added field 'accessBank' and original symbol operand
5207 in register definition,
5208 * removed the field isMapped from register definition,
5210 ** Several functions have been removed from various sources:
5211 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5212 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5213 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5214 pic16_assignRelocatableRegisters
5216 ** others have been introduced:
5217 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5218 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5220 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5222 * support/scripts/inc2h.pl: changed definition of BIT_AT
5223 to emit 'sbit at' instead of 'bit at'. This was a request.
5225 PIC16 port related preliminary changes:
5226 * gen.c: prefixed function popRegFromString with
5227 pic16_ and all references to it corrected
5228 * pcode.c: all pic16_pc_* hardware registers prefixed
5229 with underscore (_),
5230 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5231 * ralloc.c: newReg(): when register is REG_SFR then
5232 set address to rIdx,
5233 pic16_allocProcessorRegister(): marks register wasUsed=0
5234 pic16_writeUsedRegs(): added a call to assign processor
5235 registers via pic16_assignFixedRegisters
5237 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5239 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5240 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5241 variables in unused register banks. Also the SSEG is placed
5242 wherever there is enough space for it, and IDATA can be anywhere
5243 in internal RAM. For now compile using -Wl-Y[stack_size].
5244 The mem file is different for this option as well, since it
5245 makes no sense of talking about DSEG lenght.
5247 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5249 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5250 in certain cases, e.g. when ROM assignment, patch provided
5251 from Albert den Haan.
5253 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6276 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6277 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol

6296 A few small changes that speed up the peephole optimizer.
6300 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6302 Try to make the peephole optimizer smarter by maintaining
6303 an association between the assembly source code and the
6304 iCodes that originated them. Put this information to use
6305 with a new peephole rule condition "notVolatile" so that
6306 the rules can be aggressive yet still safe.
6311 * src/mcs51/peeph.def
6313 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6317 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6318 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6319 if the left or right operand symbols have the accuse flag set.
6321 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6323 Changed the type of the result of the ! (NOT) operator to char;
6324 previously it returned the same type as the source. This allows
6325 us to eliminate all the genFloatNot functions (all of its target
6326 implementations were very buggy) since !float can use the same

6338 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6339 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6340 during interrupts. Ensure WSAVE is located at a shared bank address.
6341 2. Fixed page selection in some places
6342 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6343 the registers name strings.
6344 4. Fixed "signed / unsigned compare" compiler warnings.
6345 5. The PIC port manages its own allocation of the general purpose
6346 registers, but makes no attempt to reuse them. As a result when
6347 compiling it soon runs out of general purpose registers. Some
6348 additional code was added to the files pcode.c and device.c to walk
6349 through the function call tree and rename the registers so that they
6359 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

6366 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6368 Made bitfield a distinct type from bit so that bitfields
6369 convert as per ANSI C and bits retain their traditional
6370 boolean style behaviour. Implemented bitfield support in
6378 * src/ds390/gen.c: bit v bitfield split
6379 * src/z80/gen.c: New support for bitfields

6386 access to xdata mapped I/O devices.
6388 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6390 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6392 Cleaned up genPackBits and genUnpackBits and added two helper
6393 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6394 for literal assignments in genPackBits (thanks to Frieder for
6400 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6402 Fixed bug #748310 (pointer to function type mishandled when the
6403 function name is omitted). Also fixed a SIGSEGV when a function
6404 attribute (reentrant, etc) is used on a non-function or on a

6432 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6434 Made the constant following the "interrupt" keyword optional. If
6435 omitted, the function will not automatically be given an entry
6436 in the interrupt vector table (similar to #pragma NOIV, but
6437 less syntacticly kludgy). The interrupt number is also now
6438 range checked. Also fixed a bug in the high order bit example

6953 * doc/sdccman.lyx: fixed bug 739745
6954 * src/pic16/pcode.c (pic16_get_op): fixed warning on alpha
6956 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
6958 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
6959 it can be defined with CFLAGS when running configure
6960 * src/SDCCmain.c: fixed compiling + linking with object files
6962 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
6964 * configure.in: configure for pic16 port,
6965 added --disable-pic16-port
6966 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
6967 * src/SDCCmain.c: linkOptions is changed to set *,
6968 added if/endif conditional macros to remove options help
6969 messages from optionsTable when a port is not configured, added
6970 support for the PIc16 port in the ports table, when executing
6971 the compiler with no port specified on command line, a default
6972 port is selected with the new macro DEFAULT_PORT which is
6973 defined in port.h, in setDefaultOptions() linkOptions is removed
6974 from initialization assignment, since now it is a set,
6975 parseCmdLine uses setParseWithComma for linkOptions, in
6976 linkEdit() linkOptions are accessed with new function indexSet()
6977 which returns the i'th item of a set variable. See SDCCset.c, in
6978 linkEdit() when calling buildCmdLine(), added linkOptions as
6979 last argument. Now users can pass arguments to gplink via the
6980 -Wl option, main() uses pic16glue() to glue up pic16 programs
6981 * src/SDCCpeeph.c: various changes to support pic16
6982 * src/SDCCset.c: added function void *indexSet(set *, int) to

6992 * src/pic16/glue.c: commented out some error producing lines
6993 * src/pic16/main.c: __config directives are commented out to stop
6994 gpasm complaining and test the linkage with gplink, _linkCmd and
6995 _asmCmd changed to be more gplink and gpasm friendly
6996 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6997 produced an error when parsed, peep rule 12 is added to utilize
6998 movff, but it is commented out since the pCode does not support
6999 yet a command with 2 address arguments
7001 2003-05-18 <johan AT balder>

7030 2003-05-11 Borut Razem <borut.razem AT siol.net>
7032 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7033 the path of bin directory, so that PATH is the only env. variable, which has to be set

8038 * src/SDCCicode.c: fixed array add
8040 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
8041 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
8042 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
8044 2003-01-04 <johan AT balder>
8046 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8048 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8049 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
8051 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
8052 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

8061 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8062 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8064 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8066 * in \sdcc\as\mcs51\ changed these files in order to create an
8067 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8068 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8069 following files to include the previous two files: aslink.dsp,
8070 Makefile.aslink, Makefile.bcc, and Makefile.in.
8072 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8073 .adb instead of .cdb
8075 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8077 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8078 value from option --iram-size.
8080 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8082 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8085 2002-09-18 <wiml AT hhhh.org>
8087 * SDCClrange.h: exposed setFromRange() and setToRange()
8088 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8089 packRegsForAccUse() (bug 542397)
8090 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8091 multiple times and emitting the fetch operations more than once
8092 added aopGetUsesAcc() function to allow binary operators to
8093 fetch their operands in the correct order; made genMinus() emit
8094 compact code for X = LITERAL - Y
8096 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8097 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8098 sprintf() in line 1267.
8100 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8101 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8104 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8105 Changes to aslink (All the changes are marked with 'JCF'):
8107 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8110 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8111 area BSEG. Also moves, if possible, the DATA area down into the internal
8112 ram so more space is available.
8114 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8117 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8118 not bytes. Function summary() which creates a memory usage summary
8119 file with extension .mem. Reports of overlaping stack and small stack
8120 size. If the space for the stack is less than 16 bytes aslink trows a
8123 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8124 the 8051. Option 'y' for memory summary output file.
8126 Changes to sdcc (All the changes are marked with 'JCF'):
8128 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8130 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8131 overlaying area for it (uses RegBankUsed[4]).
8133 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8134 bank zero as used by default. By default aslink locates the stack
8135 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8136 the creation of the .mem file. Delegates the allocation of data area
8137 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8138 the begining of the stack area to aslink.
8140 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8141 glue() in SDCCglue.c creates an area for it.
8143 2002-09-03 Borut Razem <borut.razem AT siol.net>
8144 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8145 sdcc/src/pic/glue.c:
8146 introduced atexit() handler for teporay files removal in case of
8147 errors, assertions, ...
8149 2002-08-29 Borut Razem <borut.razem AT siol.net>
8150 * sdcc/support/cpp2/auto-host_vc_in.h:
8151 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8152 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8153 Maybe there is a similar problem with BORLANDC? It should be checked!
8155 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8156 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8157 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8158 was not executed, and the compiler (cl) launched a warning:
8159 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8161 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8162 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8164 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8165 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8167 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8168 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8169 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8170 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8171 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8172 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8173 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8174 - added Release configuration in VS projects
8175 - review of compiler an linker options
8176 - VC .exe files are generated in bin_vc directory, not to interfere
8177 with binaries generated from other projects (cygwin, mingw, bcc ...)
8179 * sdcc/src/yacc.dsp: added
8181 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8182 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8183 and insert the version number definitions from .version
8185 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8187 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8188 added - genarate auto-host.h using auto-host_vc_in.h as template
8191 removed from CVS, generated automatically
8193 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8194 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8196 2002-08-11 Borut Razem <borut.razem AT siol.net>
8197 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8199 2002-08-10 Borut Razem <borut.razem AT siol.net>
8200 * src/SDCCmain.c (main):
8201 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8202 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8203 The consequence was that some temporary files were not removed.
8206 unification of code in functions tempfilename() and tempfile():
8207 function tempnam() is defined in Visual Studio 6.0 and .NET
8209 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8211 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8212 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8213 - removed compiler command line option /WX: Treats all warnings as errors
8214 - update a list of source files, included into the project
8216 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8217 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8218 changed project type to Generic Project so that can be correcly converted to VS.NET project
8220 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8222 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8224 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8226 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8227 added return 0 statements after assert() to make compiler happy
8229 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8230 added newline in the def file to keep MSC compiler satisfied
8232 * sdcc/src/z80/gen.c:
8233 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8234 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8235 - solved MSC error in function aopDump()
8237 * sdcc_vc.h: define PREFIX as "\\sdcc"
8239 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8240 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
8242 2002-06-22 Scott Dattalo <scott AT dattalo.com>
8243 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
8244 - Rewrote the register banking algorithm.
8245 - Added pCode live-range analysis to registers (for now, only non-used and
8246 singly-used registers optimized away)
