906 * src/SDCCBBlock.c (iCodeBreakDown, dumpEbbsToFileExt, eBBWithEntryLabel),
907 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
908 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
909 immedDom() returning wrong block; probably fixes bug #1160833)
911 2005-03-20 Borut Razem <borut.razem AT siol.net>
913 * support/scripts/inc2h.pl: WIN32 port
915 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
917 * device/lib/makefile.in: added abs.c and labs.c
919 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
921 * device/include/stdint.h: added
922 * device/lib/abs.c: added
923 * device/lib/labs.c: added
924 * device/include/stdlib.h: added abs() and labs() prototypes
925 * device/lib/libsdcc.lib: added abs and labs
926 * device/include/float.h,
927 * device/lib/_fsmul.c,
928 * device/lib/printf_fast.c,
929 * device/lib/printf_tiny.c: updated comments
931 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
933 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
936 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
938 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
939 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
941 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
943 * device/lib/printf_large.c: removed inline assembly for portability and
944 readability. Use printf_fast if speed or size are more important.
945 * src/pic16/gen.c: removed conditions around use of DEBUGpc
946 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
948 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
950 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
951 prevent compiler warning
953 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
955 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
956 moved to level 0 and declared as static. Also they are explicit
957 placed in access bank. This was necessery because some times they
958 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
959 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
960 optimizations. Currently only compare to unsigned char is implemented,
961 * src/pic16/gen.c: added fReturnIdx array,
962 * (struct resolvedIfx) is moved to gen.h and made public,
963 * (struct _G): added sregsAlloc and sregsAllocSet fields,
964 * (aopForSym): added an optimization to directly store in stack of
965 the operand of a SEND iCode,
966 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
967 but as registers instead (AOP_REG) using the fReturnIdx array,
968 * (pic16_freeAsmop): remove the freed register from the
970 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
972 * (pic16_popGetTempRegCond): changed function prototype, now
973 function takes also a bitVector argument v which holds the current
974 set of registers that are allocated for stack access by aopForSym,
975 registers allocated in aopForSym for accessing stack symbols are not
976 any more part of the functions usedRegs field,
977 * (genCall): some times aopOp is called for a stack variable to be
978 send, aopForSym might perform the push, if this is true make sure
979 that genCall doesn't push the variable twice by testing _G.resDirect,
980 * (genFunction): changed testing for unspecified interrupt number
981 from 256 to INTNO_UNSPEC,
982 * modified selection scheme of frame pointer generation. Previously
983 if function did use local registers a frame pointer was generated,
984 now a frame pointer is generated only if function has arguments
985 (that need PLUSW2 register access), or has stack arguments, or the
986 compiler is not instructed to omit the frame pointer,
987 * (genEndFunction): before restoring local registers that were saved
988 in the function preamble, also restore the registers that *might*
989 have been allocated for stack access,
990 * (genRet): removed some old comments,
991 * (genCmp, the active (RN's) version): added a call to the
992 pic16_genCmp_special function to perform the compare with a more
993 robust and optimized way,
994 * (genInline): a feature has been added in inline code generation,
995 which allows a wildcard variable substitution when writing inline
996 assembly. Code is incomplete and experimental therefore undocumented,
997 * (genCast): changed order of aopOp for result and right to allow
998 aopForSym to directly load the result if possible,
999 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1000 perform an optimized compare on some selected special occasions,
1001 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1002 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1003 generate an IVT any more,
1004 * src/pic16/main.c (pic16_optionsTable): added command line option
1006 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1007 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1009 * src/pic16/NOTES: Raphael Neider added in list of active developers
1010 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1011 jumptable_end to prevent bug #,
1012 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1013 inCond and outCond fields,
1014 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1015 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1016 turn off register spilling,
1017 * (packRegsForOneUse): synced with other ports' versions although it
1018 is not used currently,
1019 * (pic16_packRegisters): added an optimization while reading
1020 structure bitfields, some registers may be saved (malloc code is
1021 decreased by 80 bytes)
1023 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1025 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1026 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1027 this can be optimized more?
1029 2005-03-10 Raphael Neider <rneider AT web.de>
1031 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1032 genNearPointerGet): (hopefully) fixed access to bitfields via
1033 pointers (p->bitN = x; and x = p->bitN; failed)
1035 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
1037 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

1076 2005-02-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
1078 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
1079 to keep the correct label reference count when adding/removing references
1080 to labels. A peephole file using this is appended to patch #1144962.

1222 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
1223 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
1224 this might fix SIGSEGVs on MinGW...

1226 (volatile operands might get thrown away though)
1228 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

1312 * (genUminus): rewritten to for efficiency
1313 * (genNearPointer[GS]et): enforce reloading of FSR0 (was still
1314 used uninitialized in some cases)
1315 * (genCast): upcasting a 16bit int to a 24bit GPOINTER may not
1316 copy the third byte from the int -- now assumes 0x80 (data memory)
1317 * src/pic16/genarith.c (pic16_genPlus): fixed bug when swapping

1705 * added libc directory. The current version of LibC contains string
1706 functions, ctype functions and macros and some functions of the
1707 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1708 be extensively tested in the future. Standard disclaimer here.
1709 Library is not automatically build yet. But one can build it by

1721 * (pic16_storeForReturn): optimized return of 0,
1722 * (genCmp): experimental code for new genCmp which uses PIC18's
1723 special compare&skip instructions. Initial tests fail some times
1724 with variables grater than 1 byte in size, so new code is disabled,
1725 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1727 * (genCast): began a fix to optimize the casting of a bit to another
1728 bit, now assigning a bitfield to another bitfield will fail, sorry,

1737 and 1 for banking instruction,
1738 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1739 caused stop processing pCodes after a inline assembly block,

1742 registers when it shouldn't,
1743 * src/pic16/ralloc.c (allocReg): add preliminary support for
1744 supporting a limited set of temporary registers,
1746 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

1752 (genFunction): optimize RECEIVE iCodes in reentrant functions
1754 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4751 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4753 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4754 loaded with the linker search paths (-L arguments) and the libraries
4755 to be linked with the current source (-l arguments). Changes
4756 currently will affect only the pic16 port.
4757 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4758 include path the port specific paths and port specific libraries,
4759 * gplink command now contains the $3 argument,
4760 * src/pic16/device.h,
4761 * src/pic16/device.c,: structure PIC_device is made public and
4762 renamed to PIC16_device, the same for variable Pics which is renamed

4777 Documenting changes from previous commits.
4778 * configure.in (version 1.56),
4779 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4780 when generating output files to configure the pic16 library,
4781 but now I've commented it out, since gputils aren't installed in the
4782 SF compile farm, so library won't compile
4784 * device/lib/Makefile.in (version 1.56): initially I've added in
4785 target 'all' the prerequestive 'model-pic16' so it compiled the
4786 pic16 library, but now I've commented it out for the same reasons
4788 * added targets 'model-pic16' and 'objects-pic16' to compile the
4790 * added target 'port-specific-objects-pic16' to handle the
4791 generated libraries and copy them into the build/ directory
4792 * added target 'clean-intermediate-pic16' to clean intermediate
4793 files into pic16 directory
4794 * in target 'installdirs' added line to create directory pic16 in
4795 the installation path
4797 * device/include/Makefile.in (version 1.11): in target 'install'
4798 added lines to copy all header files to installation path,
4799 * in target 'installdirs' added line create directory for pic16
4800 headers in the installation path

4815 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4816 option so that it actually works. Made it specific to the z80, since
4817 the gbz80 doesn't have these kinds of I/O ports.
4819 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4821 * device/include/z180.h,

4845 via literal number. The symbol is placed in the corresponding
4846 position of the data ram
4847 * (pic16_dump_section): relocatable and absolute uninitialized
4848 data are now emitted in sorted order to reduce section naming,
4849 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4850 weren't marked as being in the access bank,
4852 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4854 Added portion of GNU PIC Library under the directory
4855 device/include/pic16 and device/lib/pic16. These files
4856 contain the declarations of SFRs for the PIC18Fxx2 devices.
4857 The directory is initialized via configure from toplevel.
4859 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

4886 * doc/sdccman.lyx: Moved and added some sections, small changes
4887 all over. Telling LaTeX to be less strict with word spacing
4888 to better keep the right margin. Changed some notes about
4889 maintainance of the ports in section 3.2.1 - is it OK like this?
4891 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
4893 SDCC source changes:
4894 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

5043 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5045 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5046 (default behaviour).
5048 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5050 A python script to validate compiler diagnostic messages. It can be
5051 used to verify that sdcc complains about bad c source code and
5052 gives a good location of the error.
5053 * support/valdiag/Makefile,
5054 * support/valdiag/valdiag.py,
5055 * support/valdiag/tests/*

5072 Bug reported from Jesus Calvino-Fraga
5074 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5076 * sdcc.spec: updated
5077 * device/include/Makefile.in: don't install CVS directories
5078 * device/lib/Makefile.in: added removal of CVS directories after install
5079 * doc/Makefile: fixed install, added local_icons
5080 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5081 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5082 * src/ds390/gen.c (genRightShift): fixed bug #870788
5083 * src/SDCCast.c (decorateType): fixed bug #870781
5085 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5087 PIC16 port related changes:
5088 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5089 added variable stackPos,
5091 * gen.c: genCall, assignResultValue: added support for
5092 pushing/retrieving function parameters to/from stack,
5093 genFunction,genEndFunction: setup stack frame for the
5095 genAddrOf: will be changed according to bug 863624
5097 * added files genutils.c and genutils.h which contain gen*
5098 debugged and optimised functions extracted from gen.c
5100 * glue.c: added variable 'externs' which holds extern symbols,
5101 pic16emitRegularMap: is modified to properly handle relocatable
5102 symbols under the new scheme,
5103 pic16createInterruptVect: is modified
5104 pic16printPublics: is modified to emit 'global' assembler directives,
5105 added pic16_printExterns to print extern symbols,
5106 pic16glue: initializes stack/frame pointer in the beginning of
5107 the assembly output. Temporary hack, will be corrected later,
5108 because gplink yet does not support stack and SDCC does not
5109 yet support a type of crt0.o object to create the final binary.
5111 * Removed many lines that contain 8051 legacy code.
5112 * The code is finally placed under a 'code' directive.
5113 * Added port specific options.
5115 * _process_pragma: simplified since now we do not need *special*
5116 include file to define SFR registers. But a separate header
5117 will be needed. This will be developed later.
5118 * _pic16_parseOptions: added, parses port specific options:
5119 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5120 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5121 --preplace-udata-with=
5123 * _pic16_setDefaultOptions: modified to initialize section names,
5124 but hack is temporarly out of order since it needs improvement.
5125 * _pic16_genAssemblerPreamble: configuration words are emitted by
5126 their address instead of their name. This part is incomplete and
5127 supports only the 18Fxx2 devices. Other devices will emit an error
5128 during assembly since they do not contain the same set of config
5130 * _pic16_genIVT: is modified,
5132 * pcode.c: added definitions for some hardware registers that are needed
5134 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5135 All PCI entries are updated. Now LFSR is supported.
5136 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5137 * added pic16_newpCodeOpLit2 to support instructions with
5138 two literal arguments
5139 * pic16_pCode2str: corrected code that emits assembler instructions
5140 with two literal operands and those that have an access bit modifier
5141 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5142 this fixes a bug which caused some labels to be lost, when an
5143 assembler directive was added, i.e. banksel,
5144 * pic16_FixRegisterBanking: improved logic that causes the insertion
5146 * InlineFunction: functions that are called once, are not any more
5147 inlined. This can be a port option in the future,
5149 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5151 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5152 hold the corresponding uninitialized symbols,
5153 * pic16_allocProcessorRegister: registers have explicit marked the
5155 * pic16_allocInternalRegister: registers are explicit marked as
5157 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5158 processing list, so bit registers were lost,
5161 * ralloc.h: added field 'accessBank' and original symbol operand
5162 in register definition,
5163 * removed the field isMapped from register definition,
5165 ** Several functions have been removed from various sources:
5166 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5167 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5168 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5169 pic16_assignRelocatableRegisters
5171 ** others have been introduced:
5172 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5173 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5175 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5177 * support/scripts/inc2h.pl: changed definition of BIT_AT
5178 to emit 'sbit at' instead of 'bit at'. This was a request.
5180 PIC16 port related preliminary changes:
5181 * gen.c: prefixed function popRegFromString with
5182 pic16_ and all references to it corrected
5183 * pcode.c: all pic16_pc_* hardware registers prefixed
5184 with underscore (_),
5185 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5186 * ralloc.c: newReg(): when register is REG_SFR then
5187 set address to rIdx,
5188 pic16_allocProcessorRegister(): marks register wasUsed=0
5189 pic16_writeUsedRegs(): added a call to assign processor
5190 registers via pic16_assignFixedRegisters
5192 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5194 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5195 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5196 variables in unused register banks. Also the SSEG is placed
5197 wherever there is enough space for it, and IDATA can be anywhere
5198 in internal RAM. For now compile using -Wl-Y[stack_size].
5199 The mem file is different for this option as well, since it
5200 makes no sense of talking about DSEG lenght.
5202 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5204 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5205 in certain cases, e.g. when ROM assignment, patch provided
5206 from Albert den Haan.
5208 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5351 * src/mcs51/peephole.def,
5352 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

6231 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6232 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6233 type for bits was changed. It resulted in bit variables becoming

6251 A few small changes that speed up the peephole optimizer.
6255 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6257 Try to make the peephole optimizer smarter by maintaining
6258 an association between the assembly source code and the
6259 iCodes that originated them. Put this information to use
6260 with a new peephole rule condition "notVolatile" so that
6261 the rules can be aggressive yet still safe.
6266 * src/mcs51/peeph.def
6268 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6272 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6273 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6274 if the left or right operand symbols have the accuse flag set.
6276 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6278 Changed the type of the result of the ! (NOT) operator to char;
6279 previously it returned the same type as the source. This allows
6280 us to eliminate all the genFloatNot functions (all of its target
6281 implementations were very buggy) since !float can use the same
6284 * src/SDCCicode.c (ast2iCode): ! returns char

6293 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6294 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6295 during interrupts. Ensure WSAVE is located at a shared bank address.
6296 2. Fixed page selection in some places
6297 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6298 the registers name strings.
6299 4. Fixed "signed / unsigned compare" compiler warnings.
6300 5. The PIC port manages its own allocation of the general purpose
6301 registers, but makes no attempt to reuse them. As a result when
6302 compiling it soon runs out of general purpose registers. Some
6303 additional code was added to the files pcode.c and device.c to walk
6304 through the function call tree and rename the registers so that they
6314 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6315 genPlus() & genMinus() when the result is the same as left or right

6321 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6323 Made bitfield a distinct type from bit so that bitfields
6324 convert as per ANSI C and bits retain their traditional
6325 boolean style behaviour. Implemented bitfield support in
6333 * src/ds390/gen.c: bit v bitfield split
6334 * src/z80/gen.c: New support for bitfields
6335 * support/regression/tests/bitfields.c: reenabled z80,
6338 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6340 Rules 246.x, 247.x relate to bitfields, the others speed up
6341 access to xdata mapped I/O devices.
6343 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6345 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6347 Cleaned up genPackBits and genUnpackBits and added two helper

6357 Fixed bug #748310 (pointer to function type mishandled when the
6358 function name is omitted). Also fixed a SIGSEGV when a function
6359 attribute (reentrant, etc) is used on a non-function or on a
6360 function but misplaced before the parameter list.

6387 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6389 Made the constant following the "interrupt" keyword optional. If
6390 omitted, the function will not automatically be given an entry
6391 in the interrupt vector table (similar to #pragma NOIV, but
6392 less syntacticly kludgy). The interrupt number is also now
6393 range checked. Also fixed a bug in the high order bit example
6400 * support/Util/SDCCerr.c
6401 * support/Util/SDCCerr.h

6925 support for the PIc16 port in the ports table, when executing
6926 the compiler with no port specified on command line, a default
6927 port is selected with the new macro DEFAULT_PORT which is
6928 defined in port.h, in setDefaultOptions() linkOptions is removed
6929 from initialization assignment, since now it is a set,
6930 parseCmdLine uses setParseWithComma for linkOptions, in
6931 linkEdit() linkOptions are accessed with new function indexSet()
6932 which returns the i'th item of a set variable. See SDCCset.c, in
6933 linkEdit() when calling buildCmdLine(), added linkOptions as
6934 last argument. Now users can pass arguments to gplink via the
6935 -Wl option, main() uses pic16glue() to glue up pic16 programs

7999 2003-01-04 <johan AT balder>
8001 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8003 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8004 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
8006 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
8007 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

8016 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8017 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8019 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8021 * in \sdcc\as\mcs51\ changed these files in order to create an
8022 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8023 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8024 following files to include the previous two files: aslink.dsp,
8025 Makefile.aslink, Makefile.bcc, and Makefile.in.
8027 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8028 .adb instead of .cdb
8030 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8032 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8033 value from option --iram-size.
8035 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8037 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8040 2002-09-18 <wiml AT hhhh.org>
8042 * SDCClrange.h: exposed setFromRange() and setToRange()
8043 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8044 packRegsForAccUse() (bug 542397)
8045 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8046 multiple times and emitting the fetch operations more than once
8047 added aopGetUsesAcc() function to allow binary operators to
8048 fetch their operands in the correct order; made genMinus() emit
8049 compact code for X = LITERAL - Y
8051 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8052 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8053 sprintf() in line 1267.
8055 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8056 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8059 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8060 Changes to aslink (All the changes are marked with 'JCF'):
8062 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8065 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8066 area BSEG. Also moves, if possible, the DATA area down into the internal
8067 ram so more space is available.
8069 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8072 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8073 not bytes. Function summary() which creates a memory usage summary
8074 file with extension .mem. Reports of overlaping stack and small stack
8075 size. If the space for the stack is less than 16 bytes aslink trows a
8078 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8079 the 8051. Option 'y' for memory summary output file.
8081 Changes to sdcc (All the changes are marked with 'JCF'):
8083 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8085 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8086 overlaying area for it (uses RegBankUsed[4]).
8088 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8089 bank zero as used by default. By default aslink locates the stack
8090 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8091 the creation of the .mem file. Delegates the allocation of data area
8092 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8093 the begining of the stack area to aslink.
8095 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8096 glue() in SDCCglue.c creates an area for it.
8098 2002-09-03 Borut Razem <borut.razem AT siol.net>
8099 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8100 sdcc/src/pic/glue.c:
8101 introduced atexit() handler for teporay files removal in case of
8102 errors, assertions, ...
8104 2002-08-29 Borut Razem <borut.razem AT siol.net>
8105 * sdcc/support/cpp2/auto-host_vc_in.h:
8106 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8107 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8108 Maybe there is a similar problem with BORLANDC? It should be checked!
8110 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8111 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8112 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8113 was not executed, and the compiler (cl) launched a warning:
8114 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8116 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8117 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8119 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8120 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8122 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8123 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8124 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8125 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8126 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8127 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8128 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8129 - added Release configuration in VS projects
8130 - review of compiler an linker options
8131 - VC .exe files are generated in bin_vc directory, not to interfere
8132 with binaries generated from other projects (cygwin, mingw, bcc ...)
8134 * sdcc/src/yacc.dsp: added
8136 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8137 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8138 and insert the version number definitions from .version
8140 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8142 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8143 added - genarate auto-host.h using auto-host_vc_in.h as template
8146 removed from CVS, generated automatically
8148 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8149 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8151 2002-08-11 Borut Razem <borut.razem AT siol.net>
8152 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8154 2002-08-10 Borut Razem <borut.razem AT siol.net>
8155 * src/SDCCmain.c (main):
8156 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8157 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8158 The consequence was that some temporary files were not removed.
8161 unification of code in functions tempfilename() and tempfile():
8162 function tempnam() is defined in Visual Studio 6.0 and .NET
8164 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8166 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8167 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8168 - removed compiler command line option /WX: Treats all warnings as errors
8169 - update a list of source files, included into the project
8171 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8172 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8173 changed project type to Generic Project so that can be correcly converted to VS.NET project
8175 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8177 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8179 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8181 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8182 added return 0 statements after assert() to make compiler happy
8184 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8185 added newline in the def file to keep MSC compiler satisfied
8187 * sdcc/src/z80/gen.c:
8188 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8189 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8190 - solved MSC error in function aopDump()
8192 * sdcc_vc.h: define PREFIX as "\\sdcc"
8194 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8195 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
8197 2002-06-22 Scott Dattalo <scott AT dattalo.com>
8198 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
8199 - Rewrote the register banking algorithm.
8200 - Added pCode live-range analysis to registers (for now, only non-used and
8201 singly-used registers optimized away)
8203 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
8205 * 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.
8207 2002-05-10 Scott Dattalo <scott AT dattalo.com>
8208 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
8210 2002-04-22 Michael Hope <michaelh AT vroom>
8212 * device/lib/z80/printf.c: Changed emitter to volatile to work around a pcall bug.

8224 * src/z80/ralloc.c (packRegisters): Disabled pack HL use for GB as it's broken.
8226 * src/z80/peeph.def: Added transpose redundent load rule.
8228 * src/z80/main.c: Added force callee saves for jaune.
8230 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
8232 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
8234 2002-03-28 Johan Knol <johan AT balder>
8236 * src/SDCCval.c: fixed bug #532436
8238 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8240 Added "char *Processor" field to the port structure.
8243 Added -p option. Allows port dependent processor to be specified.
8246 Initialized the new field char *Processor field to NULL in all ports
8249 Compiler generated registers for interrupt context saving
8250 were not getting allocated.
8252 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8255 Fixed left shift. Will promote the left side of a left shift
8256 if a) left shifting more than size of operand or b) when assigned
8257 to something size > size of left side
8259 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8261 tons of changes. Register allocation has been
8262 rewritten. Added customization for the various PICs. Flow
8263 analysis is restructured. ...
8269 Added. device.c is a PIC port hack to accomodate variations
8272 2002-03-13 Michael Hope <michaelh AT vroom>
8274 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
8276 2002-03-04 johanknol <johanknol AT manik>
8278 * /src/SDCCval.c: fixed
8280 const unsigned char arr[][2] = { { 0, 1 } };
