896 * (struct _G): added sregsAlloc and sregsAllocSet fields,
897 * (aopForSym): added an optimization to directly store in stack of
898 the operand of a SEND iCode,
899 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
900 but as registers instead (AOP_REG) using the fReturnIdx array,
901 * (pic16_freeAsmop): remove the freed register from the
903 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
905 * (pic16_popGetTempRegCond): changed function prototype, now
906 function takes also a bitVector argument v which holds the current
907 set of registers that are allocated for stack access by aopForSym,
908 registers allocated in aopForSym for accessing stack symbols are not
909 any more part of the functions usedRegs field,
910 * (genCall): some times aopOp is called for a stack variable to be
911 send, aopForSym might perform the push, if this is true make sure
912 that genCall doesn't push the variable twice by testing _G.resDirect,
913 * (genFunction): changed testing for unspecified interrupt number
914 from 256 to INTNO_UNSPEC,
915 * modified selection scheme of frame pointer generation. Previously
916 if function did use local registers a frame pointer was generated,
917 now a frame pointer is generated only if function has arguments
918 (that need PLUSW2 register access), or has stack arguments, or the
919 compiler is not instructed to omit the frame pointer,
920 * (genEndFunction): before restoring local registers that were saved
921 in the function preamble, also restore the registers that *might*
922 have been allocated for stack access,
923 * (genRet): removed some old comments,
924 * (genCmp, the active (RN's) version): added a call to the
925 pic16_genCmp_special function to perform the compare with a more
926 robust and optimized way,
927 * (genInline): a feature has been added in inline code generation,
928 which allows a wildcard variable substitution when writing inline
929 assembly. Code is incomplete and experimental therefore undocumented,
930 * (genCast): changed order of aopOp for result and right to allow
931 aopForSym to directly load the result if possible,
932 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
933 perform an optimized compare on some selected special occasions,
934 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
935 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
936 generate an IVT any more,
937 * src/pic16/main.c (pic16_optionsTable): added command line option
939 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
940 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
942 * src/pic16/NOTES: Raphael Neider added in list of active developers
943 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
944 jumptable_end to prevent bug #,
945 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
946 inCond and outCond fields,
947 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
948 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
949 turn off register spilling,
950 * (packRegsForOneUse): synced with other ports' versions although it
951 is not used currently,
952 * (pic16_packRegisters): added an optimization while reading
953 structure bitfields, some registers may be saved (malloc code is
954 decreased by 80 bytes)
956 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
958 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
959 left is a bitfield, if yes, then don't optimize assignment. Perhaps
960 this can be optimized more?
962 2005-03-10 Raphael Neider <rneider AT web.de>
964 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
965 genNearPointerGet): (hopefully) fixed access to bitfields via
966 pointers (p->bitN = x; and x = p->bitN; failed)

1292 access stack and frame pointers. They are initially assigned to
1293 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
1294 accessing SFRs. Updated all occurences of modification of stack or
1295 frame pointer in gen.c and pcode.c,

1600 Adding support for replacing ljmps with sjmps in jumptables
1601 generated for switch statements. For now you need to set the
1602 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1603 Now 4 algorithms for mcs51 jumptable generation are used:
1604 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1605 addresses loaded pc-relative for up to 112 cases and stack-pushing
1606 target addresses loaded with offset from dptr for up to 256 cases.

1638 * added libc directory. The current version of LibC contains string
1639 functions, ctype functions and macros and some functions of the
1640 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1641 be extensively tested in the future. Standard disclaimer here.

1655 * (genCmp): experimental code for new genCmp which uses PIC18's
1656 special compare&skip instructions. Initial tests fail some times
1657 with variables grater than 1 byte in size, so new code is disabled,
1658 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1660 * (genCast): began a fix to optimize the casting of a bit to another
1661 bit, now assigning a bitfield to another bitfield will fail, sorry,

1675 registers when it shouldn't,
1676 * src/pic16/ralloc.c (allocReg): add preliminary support for
1677 supporting a limited set of temporary registers,
1679 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4684 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4686 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4687 loaded with the linker search paths (-L arguments) and the libraries
4688 to be linked with the current source (-l arguments). Changes
4689 currently will affect only the pic16 port.
4690 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4691 include path the port specific paths and port specific libraries,
4692 * gplink command now contains the $3 argument,
4693 * src/pic16/device.h,
4694 * src/pic16/device.c,: structure PIC_device is made public and
4695 renamed to PIC16_device, the same for variable Pics which is renamed

4710 Documenting changes from previous commits.
4711 * configure.in (version 1.56),
4712 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4713 when generating output files to configure the pic16 library,
4714 but now I've commented it out, since gputils aren't installed in the
4715 SF compile farm, so library won't compile
4717 * device/lib/Makefile.in (version 1.56): initially I've added in
4718 target 'all' the prerequestive 'model-pic16' so it compiled the
4719 pic16 library, but now I've commented it out for the same reasons
4721 * added targets 'model-pic16' and 'objects-pic16' to compile the
4723 * added target 'port-specific-objects-pic16' to handle the
4724 generated libraries and copy them into the build/ directory
4725 * added target 'clean-intermediate-pic16' to clean intermediate
4726 files into pic16 directory
4727 * in target 'installdirs' added line to create directory pic16 in

4748 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4749 option so that it actually works. Made it specific to the z80, since
4750 the gbz80 doesn't have these kinds of I/O ports.
4752 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4754 * device/include/z180.h,

4778 via literal number. The symbol is placed in the corresponding
4779 position of the data ram
4780 * (pic16_dump_section): relocatable and absolute uninitialized
4781 data are now emitted in sorted order to reduce section naming,
4782 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4783 weren't marked as being in the access bank,

4976 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4978 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4979 (default behaviour).
4981 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4983 A python script to validate compiler diagnostic messages. It can be
4984 used to verify that sdcc complains about bad c source code and
4985 gives a good location of the error.
4986 * support/valdiag/Makefile,
4987 * support/valdiag/valdiag.py,

5007 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5009 * sdcc.spec: updated

5013 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5014 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5015 * src/ds390/gen.c (genRightShift): fixed bug #870788

5018 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5020 PIC16 port related changes:
5021 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5022 added variable stackPos,
5024 * gen.c: genCall, assignResultValue: added support for
5025 pushing/retrieving function parameters to/from stack,
5026 genFunction,genEndFunction: setup stack frame for the
5028 genAddrOf: will be changed according to bug 863624
5030 * added files genutils.c and genutils.h which contain gen*
5031 debugged and optimised functions extracted from gen.c
5033 * glue.c: added variable 'externs' which holds extern symbols,
5034 pic16emitRegularMap: is modified to properly handle relocatable
5035 symbols under the new scheme,
5036 pic16createInterruptVect: is modified
5037 pic16printPublics: is modified to emit 'global' assembler directives,
5038 added pic16_printExterns to print extern symbols,
5039 pic16glue: initializes stack/frame pointer in the beginning of
5040 the assembly output. Temporary hack, will be corrected later,
5041 because gplink yet does not support stack and SDCC does not
5042 yet support a type of crt0.o object to create the final binary.
5044 * Removed many lines that contain 8051 legacy code.
5045 * The code is finally placed under a 'code' directive.
5046 * Added port specific options.
5048 * _process_pragma: simplified since now we do not need *special*
5049 include file to define SFR registers. But a separate header
5050 will be needed. This will be developed later.
5051 * _pic16_parseOptions: added, parses port specific options:
5052 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5053 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5054 --preplace-udata-with=
5056 * _pic16_setDefaultOptions: modified to initialize section names,
5057 but hack is temporarly out of order since it needs improvement.
5058 * _pic16_genAssemblerPreamble: configuration words are emitted by
5059 their address instead of their name. This part is incomplete and
5060 supports only the 18Fxx2 devices. Other devices will emit an error
5061 during assembly since they do not contain the same set of config
5063 * _pic16_genIVT: is modified,
5065 * pcode.c: added definitions for some hardware registers that are needed
5067 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5068 All PCI entries are updated. Now LFSR is supported.
5069 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5070 * added pic16_newpCodeOpLit2 to support instructions with
5071 two literal arguments
5072 * pic16_pCode2str: corrected code that emits assembler instructions
5073 with two literal operands and those that have an access bit modifier
5074 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5075 this fixes a bug which caused some labels to be lost, when an
5076 assembler directive was added, i.e. banksel,
5077 * pic16_FixRegisterBanking: improved logic that causes the insertion
5079 * InlineFunction: functions that are called once, are not any more
5080 inlined. This can be a port option in the future,
5082 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5084 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5085 hold the corresponding uninitialized symbols,
5086 * pic16_allocProcessorRegister: registers have explicit marked the
5088 * pic16_allocInternalRegister: registers are explicit marked as
5090 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5091 processing list, so bit registers were lost,
5094 * ralloc.h: added field 'accessBank' and original symbol operand
5095 in register definition,
5096 * removed the field isMapped from register definition,
5098 ** Several functions have been removed from various sources:
5099 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5100 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5101 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5102 pic16_assignRelocatableRegisters
5104 ** others have been introduced:
5105 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5106 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5108 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5110 * support/scripts/inc2h.pl: changed definition of BIT_AT
5111 to emit 'sbit at' instead of 'bit at'. This was a request.
5113 PIC16 port related preliminary changes:
5114 * gen.c: prefixed function popRegFromString with
5115 pic16_ and all references to it corrected
5116 * pcode.c: all pic16_pc_* hardware registers prefixed
5117 with underscore (_),
5118 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5119 * ralloc.c: newReg(): when register is REG_SFR then
5120 set address to rIdx,
5121 pic16_allocProcessorRegister(): marks register wasUsed=0
5122 pic16_writeUsedRegs(): added a call to assign processor
5123 registers via pic16_assignFixedRegisters
5125 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5127 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5128 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5129 variables in unused register banks. Also the SSEG is placed
5130 wherever there is enough space for it, and IDATA can be anywhere
5131 in internal RAM. For now compile using -Wl-Y[stack_size].
5132 The mem file is different for this option as well, since it
5133 makes no sense of talking about DSEG lenght.
5135 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5137 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5138 in certain cases, e.g. when ROM assignment, patch provided
5139 from Albert den Haan.

6144 fetching of the pointer
6145 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
6146 copied from genNearPointerSet()
6147 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
6148 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

6162 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
6164 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6165 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6166 type for bits was changed. It resulted in bit variables becoming
6167 global, which is not permitted in PIC 14 assembly output.
6169 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6171 * doc/sdccman.lyx: various additions and updates. Rearranged sections

6184 A few small changes that speed up the peephole optimizer.
6188 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6190 Try to make the peephole optimizer smarter by maintaining
6191 an association between the assembly source code and the
6192 iCodes that originated them. Put this information to use
6193 with a new peephole rule condition "notVolatile" so that
6194 the rules can be aggressive yet still safe.
6199 * src/mcs51/peeph.def
6201 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6205 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6206 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6207 if the left or right operand symbols have the accuse flag set.
6209 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6211 Changed the type of the result of the ! (NOT) operator to char;
6212 previously it returned the same type as the source. This allows
6213 us to eliminate all the genFloatNot functions (all of its target
6214 implementations were very buggy) since !float can use the same
6217 * src/SDCCicode.c (ast2iCode): ! returns char
6218 * src/mcs51/gen.c (genNot, genNotFloat),
6219 * src/ds390/gen.c (genNot, genNotFloat),
6220 * src/z80/gen.c (genNot, genNotFloat),
6221 * src/pic/gen.c (genNot, genNotFloat),
6222 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
6224 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
6226 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6227 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6228 during interrupts. Ensure WSAVE is located at a shared bank address.
6229 2. Fixed page selection in some places
6230 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6231 the registers name strings.
6232 4. Fixed "signed / unsigned compare" compiler warnings.
6233 5. The PIC port manages its own allocation of the general purpose
6234 registers, but makes no attempt to reuse them. As a result when
6235 compiling it soon runs out of general purpose registers. Some
6236 additional code was added to the files pcode.c and device.c to walk
6237 through the function call tree and rename the registers so that they
6247 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6248 genPlus() & genMinus() when the result is the same as left or right
6250 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6254 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6256 Made bitfield a distinct type from bit so that bitfields
6257 convert as per ANSI C and bits retain their traditional
6258 boolean style behaviour. Implemented bitfield support in
6266 * src/ds390/gen.c: bit v bitfield split
6267 * src/z80/gen.c: New support for bitfields
6268 * support/regression/tests/bitfields.c: reenabled z80,
6271 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6273 Rules 246.x, 247.x relate to bitfields, the others speed up
6274 access to xdata mapped I/O devices.
6276 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6278 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6280 Cleaned up genPackBits and genUnpackBits and added two helper
6281 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6282 for literal assignments in genPackBits (thanks to Frieder for
6288 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6290 Fixed bug #748310 (pointer to function type mishandled when the
6291 function name is omitted). Also fixed a SIGSEGV when a function
6292 attribute (reentrant, etc) is used on a non-function or on a
6293 function but misplaced before the parameter list.
6295 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6297 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
6298 * support/Util/SDCCerr.h,
6299 * support/Util/SDCCerr.c: Added func attr misuse error msg
6301 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
6303 Fixed bug #787649 by anonymous
6304 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr

6320 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6322 Made the constant following the "interrupt" keyword optional. If
6323 omitted, the function will not automatically be given an entry
6324 in the interrupt vector table (similar to #pragma NOIV, but
6325 less syntacticly kludgy). The interrupt number is also now
6326 range checked. Also fixed a bug in the high order bit example

6337 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
6339 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
6340 * src/SDCCicode.c (operandOperation): rewritten some ops
6341 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
6342 * src/SDCCsymt.c (computeType): literals are handled the same way as any
6344 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
6345 be re-activated by defining REDUCE_LITERALS)
6346 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
6347 unsigned, but are signed by default
6348 * src/SDCCval.c (constVal): rearranged
6349 * src/SDCCval.c (valMod): preliminary fix
6350 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6856 added if/endif conditional macros to remove options help
6857 messages from optionsTable when a port is not configured, added
6858 support for the PIc16 port in the ports table, when executing
6859 the compiler with no port specified on command line, a default
6860 port is selected with the new macro DEFAULT_PORT which is
6861 defined in port.h, in setDefaultOptions() linkOptions is removed
6862 from initialization assignment, since now it is a set,
6863 parseCmdLine uses setParseWithComma for linkOptions, in
6864 linkEdit() linkOptions are accessed with new function indexSet()
6865 which returns the i'th item of a set variable. See SDCCset.c, in
6866 linkEdit() when calling buildCmdLine(), added linkOptions as
6867 last argument. Now users can pass arguments to gplink via the
6868 -Wl option, main() uses pic16glue() to glue up pic16 programs

6882 gpasm complaining and test the linkage with gplink, _linkCmd and
6883 _asmCmd changed to be more gplink and gpasm friendly
6884 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6885 produced an error when parsed, peep rule 12 is added to utilize
6886 movff, but it is commented out since the pCode does not support
6887 yet a command with 2 address arguments
6889 2003-05-18 <johan AT balder>
6891 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6914 2003-05-12 Borut Razem <borut.razem AT siol.net>
6916 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
6918 2003-05-11 Borut Razem <borut.razem AT siol.net>
6920 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
6921 the path of bin directory, so that PATH is the only env. variable, which has to be set
6922 in case of standard installation.

7930 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
7932 2003-01-04 <johan AT balder>
7934 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7936 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7937 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o

7949 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7950 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7952 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7954 * in \sdcc\as\mcs51\ changed these files in order to create an
7955 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7956 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7957 following files to include the previous two files: aslink.dsp,
7958 Makefile.aslink, Makefile.bcc, and Makefile.in.
7960 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7961 .adb instead of .cdb
7963 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7965 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7966 value from option --iram-size.
7968 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7970 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7973 2002-09-18 <wiml AT hhhh.org>
7975 * SDCClrange.h: exposed setFromRange() and setToRange()
7976 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7977 packRegsForAccUse() (bug 542397)
7978 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7979 multiple times and emitting the fetch operations more than once
7980 added aopGetUsesAcc() function to allow binary operators to
7981 fetch their operands in the correct order; made genMinus() emit
7982 compact code for X = LITERAL - Y
7984 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7985 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7986 sprintf() in line 1267.
7988 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7989 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7992 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7993 Changes to aslink (All the changes are marked with 'JCF'):
7995 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7998 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7999 area BSEG. Also moves, if possible, the DATA area down into the internal
8000 ram so more space is available.
8002 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8005 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8006 not bytes. Function summary() which creates a memory usage summary
8007 file with extension .mem. Reports of overlaping stack and small stack
8008 size. If the space for the stack is less than 16 bytes aslink trows a
8011 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8012 the 8051. Option 'y' for memory summary output file.
8014 Changes to sdcc (All the changes are marked with 'JCF'):
8016 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8018 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8019 overlaying area for it (uses RegBankUsed[4]).
8021 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8022 bank zero as used by default. By default aslink locates the stack
8023 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8024 the creation of the .mem file. Delegates the allocation of data area
8025 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8026 the begining of the stack area to aslink.
8028 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8029 glue() in SDCCglue.c creates an area for it.
8031 2002-09-03 Borut Razem <borut.razem AT siol.net>
8032 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8033 sdcc/src/pic/glue.c:
8034 introduced atexit() handler for teporay files removal in case of
8035 errors, assertions, ...
8037 2002-08-29 Borut Razem <borut.razem AT siol.net>
8038 * sdcc/support/cpp2/auto-host_vc_in.h:
8039 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8040 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8041 Maybe there is a similar problem with BORLANDC? It should be checked!
8043 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8044 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8045 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8046 was not executed, and the compiler (cl) launched a warning:
8047 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8049 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8050 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8052 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8053 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8055 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8056 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8057 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8058 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8059 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8060 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8061 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8062 - added Release configuration in VS projects
8063 - review of compiler an linker options
8064 - VC .exe files are generated in bin_vc directory, not to interfere
8065 with binaries generated from other projects (cygwin, mingw, bcc ...)
8067 * sdcc/src/yacc.dsp: added
8069 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8070 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8071 and insert the version number definitions from .version
8073 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8075 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8076 added - genarate auto-host.h using auto-host_vc_in.h as template
8079 removed from CVS, generated automatically
8081 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8082 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8084 2002-08-11 Borut Razem <borut.razem AT siol.net>
8085 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8087 2002-08-10 Borut Razem <borut.razem AT siol.net>
8088 * src/SDCCmain.c (main):
8089 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8090 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8091 The consequence was that some temporary files were not removed.
8094 unification of code in functions tempfilename() and tempfile():
8095 function tempnam() is defined in Visual Studio 6.0 and .NET
8097 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8099 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8100 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8101 - removed compiler command line option /WX: Treats all warnings as errors
8102 - update a list of source files, included into the project
8104 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8105 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8106 changed project type to Generic Project so that can be correcly converted to VS.NET project
8108 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8110 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8112 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8114 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8115 added return 0 statements after assert() to make compiler happy
8117 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8118 added newline in the def file to keep MSC compiler satisfied
8120 * sdcc/src/z80/gen.c:
8121 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8122 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8123 - solved MSC error in function aopDump()
8125 * sdcc_vc.h: define PREFIX as "\\sdcc"
8127 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8128 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

8171 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8173 Added "char *Processor" field to the port structure.
8176 Added -p option. Allows port dependent processor to be specified.
8179 Initialized the new field char *Processor field to NULL in all ports
8182 Compiler generated registers for interrupt context saving
8183 were not getting allocated.
8185 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8188 Fixed left shift. Will promote the left side of a left shift
8189 if a) left shifting more than size of operand or b) when assigned
8190 to something size > size of left side
8192 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8194 tons of changes. Register allocation has been
8195 rewritten. Added customization for the various PICs. Flow
8196 analysis is restructured. ...
8202 Added. device.c is a PIC port hack to accomodate variations
8205 2002-03-13 Michael Hope <michaelh AT vroom>
8207 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.

8304 not really partof a loop , but live ranges used in these blocks should
8305 be live thru the entire loop, so set partOfLoop but don't add them to
