894 placed in access bank. This was necessery because some times they
895 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
896 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
897 optimizations. Currently only compare to unsigned char is implemented,
898 * src/pic16/gen.c: added fReturnIdx array,
899 * (struct resolvedIfx) is moved to gen.h and made public,
900 * (struct _G): added sregsAlloc and sregsAllocSet fields,
901 * (aopForSym): added an optimization to directly store in stack of
902 the operand of a SEND iCode,
903 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
904 but as registers instead (AOP_REG) using the fReturnIdx array,
905 * (pic16_freeAsmop): remove the freed register from the
907 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
909 * (pic16_popGetTempRegCond): changed function prototype, now
910 function takes also a bitVector argument v which holds the current
911 set of registers that are allocated for stack access by aopForSym,
912 registers allocated in aopForSym for accessing stack symbols are not
913 any more part of the functions usedRegs field,
914 * (genCall): some times aopOp is called for a stack variable to be
915 send, aopForSym might perform the push, if this is true make sure
916 that genCall doesn't push the variable twice by testing _G.resDirect,
917 * (genFunction): changed testing for unspecified interrupt number
918 from 256 to INTNO_UNSPEC,
919 * modified selection scheme of frame pointer generation. Previously
920 if function did use local registers a frame pointer was generated,
921 now a frame pointer is generated only if function has arguments
922 (that need PLUSW2 register access), or has stack arguments, or the
923 compiler is not instructed to omit the frame pointer,
924 * (genEndFunction): before restoring local registers that were saved
925 in the function preamble, also restore the registers that *might*
926 have been allocated for stack access,
927 * (genRet): removed some old comments,
928 * (genCmp, the active (RN's) version): added a call to the
929 pic16_genCmp_special function to perform the compare with a more
930 robust and optimized way,
931 * (genInline): a feature has been added in inline code generation,
932 which allows a wildcard variable substitution when writing inline
933 assembly. Code is incomplete and experimental therefore undocumented,
934 * (genCast): changed order of aopOp for result and right to allow
935 aopForSym to directly load the result if possible,
936 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
937 perform an optimized compare on some selected special occasions,
938 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
939 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
940 generate an IVT any more,
941 * src/pic16/main.c (pic16_optionsTable): added command line option
943 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
944 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
946 * src/pic16/NOTES: Raphael Neider added in list of active developers
947 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
948 jumptable_end to prevent bug #,
949 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
950 inCond and outCond fields,
951 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
952 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
953 turn off register spilling,
954 * (packRegsForOneUse): synced with other ports' versions although it
955 is not used currently,
956 * (pic16_packRegisters): added an optimization while reading
957 structure bitfields, some registers may be saved (malloc code is
958 decreased by 80 bytes)
960 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
962 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
963 left is a bitfield, if yes, then don't optimize assignment. Perhaps
964 this can be optimized more?
966 2005-03-10 Raphael Neider <rneider AT web.de>
968 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
969 genNearPointerGet): (hopefully) fixed access to bitfields via
970 pointers (p->bitN = x; and x = p->bitN; failed)

1296 access stack and frame pointers. They are initially assigned to
1297 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
1298 accessing SFRs. Updated all occurences of modification of stack or
1299 frame pointer in gen.c and pcode.c,

1605 generated for switch statements. For now you need to set the
1606 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1607 Now 4 algorithms for mcs51 jumptable generation are used:
1608 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

1642 * added libc directory. The current version of LibC contains string
1643 functions, ctype functions and macros and some functions of the
1644 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1645 be extensively tested in the future. Standard disclaimer here.

1659 * (genCmp): experimental code for new genCmp which uses PIC18's
1660 special compare&skip instructions. Initial tests fail some times
1661 with variables grater than 1 byte in size, so new code is disabled,
1662 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1664 * (genCast): began a fix to optimize the casting of a bit to another
1665 bit, now assigning a bitfield to another bitfield will fail, sorry,

1680 * src/pic16/ralloc.c (allocReg): add preliminary support for
1681 supporting a limited set of temporary registers,
1683 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4691 loaded with the linker search paths (-L arguments) and the libraries
4692 to be linked with the current source (-l arguments). Changes
4693 currently will affect only the pic16 port.
4694 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4695 include path the port specific paths and port specific libraries,
4696 * gplink command now contains the $3 argument,
4697 * src/pic16/device.h,
4698 * src/pic16/device.c,: structure PIC_device is made public and

4714 Documenting changes from previous commits.
4715 * configure.in (version 1.56),
4716 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4717 when generating output files to configure the pic16 library,
4718 but now I've commented it out, since gputils aren't installed in the
4719 SF compile farm, so library won't compile
4721 * device/lib/Makefile.in (version 1.56): initially I've added in
4722 target 'all' the prerequestive 'model-pic16' so it compiled the
4723 pic16 library, but now I've commented it out for the same reasons
4725 * added targets 'model-pic16' and 'objects-pic16' to compile the
4727 * added target 'port-specific-objects-pic16' to handle the
4728 generated libraries and copy them into the build/ directory
4729 * added target 'clean-intermediate-pic16' to clean intermediate
4730 files into pic16 directory
4731 * in target 'installdirs' added line to create directory pic16 in

4753 option so that it actually works. Made it specific to the z80, since
4754 the gbz80 doesn't have these kinds of I/O ports.
4756 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4758 * device/include/z180.h,

4980 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4982 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4983 (default behaviour).
4985 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4987 A python script to validate compiler diagnostic messages. It can be
4988 used to verify that sdcc complains about bad c source code and
4989 gives a good location of the error.
4990 * support/valdiag/Makefile,
4991 * support/valdiag/valdiag.py,
4992 * support/valdiag/tests/*

5009 Bug reported from Jesus Calvino-Fraga
5011 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5013 * sdcc.spec: updated
5014 * device/include/Makefile.in: don't install CVS directories
5015 * device/lib/Makefile.in: added removal of CVS directories after install
5016 * doc/Makefile: fixed install, added local_icons
5017 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5018 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5019 * src/ds390/gen.c (genRightShift): fixed bug #870788
5020 * src/SDCCast.c (decorateType): fixed bug #870781
5022 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5024 PIC16 port related changes:
5025 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5026 added variable stackPos,
5028 * gen.c: genCall, assignResultValue: added support for
5029 pushing/retrieving function parameters to/from stack,
5030 genFunction,genEndFunction: setup stack frame for the
5032 genAddrOf: will be changed according to bug 863624
5034 * added files genutils.c and genutils.h which contain gen*
5035 debugged and optimised functions extracted from gen.c
5037 * glue.c: added variable 'externs' which holds extern symbols,
5038 pic16emitRegularMap: is modified to properly handle relocatable
5039 symbols under the new scheme,
5040 pic16createInterruptVect: is modified
5041 pic16printPublics: is modified to emit 'global' assembler directives,
5042 added pic16_printExterns to print extern symbols,
5043 pic16glue: initializes stack/frame pointer in the beginning of
5044 the assembly output. Temporary hack, will be corrected later,
5045 because gplink yet does not support stack and SDCC does not
5046 yet support a type of crt0.o object to create the final binary.
5048 * Removed many lines that contain 8051 legacy code.
5049 * The code is finally placed under a 'code' directive.
5050 * Added port specific options.
5052 * _process_pragma: simplified since now we do not need *special*
5053 include file to define SFR registers. But a separate header
5054 will be needed. This will be developed later.
5055 * _pic16_parseOptions: added, parses port specific options:
5056 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5057 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5058 --preplace-udata-with=
5060 * _pic16_setDefaultOptions: modified to initialize section names,
5061 but hack is temporarly out of order since it needs improvement.
5062 * _pic16_genAssemblerPreamble: configuration words are emitted by
5063 their address instead of their name. This part is incomplete and
5064 supports only the 18Fxx2 devices. Other devices will emit an error
5065 during assembly since they do not contain the same set of config
5067 * _pic16_genIVT: is modified,
5069 * pcode.c: added definitions for some hardware registers that are needed
5071 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5072 All PCI entries are updated. Now LFSR is supported.
5073 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5074 * added pic16_newpCodeOpLit2 to support instructions with
5075 two literal arguments
5076 * pic16_pCode2str: corrected code that emits assembler instructions
5077 with two literal operands and those that have an access bit modifier
5078 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5079 this fixes a bug which caused some labels to be lost, when an
5080 assembler directive was added, i.e. banksel,
5081 * pic16_FixRegisterBanking: improved logic that causes the insertion
5083 * InlineFunction: functions that are called once, are not any more
5084 inlined. This can be a port option in the future,
5086 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5088 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5089 hold the corresponding uninitialized symbols,
5090 * pic16_allocProcessorRegister: registers have explicit marked the
5092 * pic16_allocInternalRegister: registers are explicit marked as
5094 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5095 processing list, so bit registers were lost,
5098 * ralloc.h: added field 'accessBank' and original symbol operand
5099 in register definition,
5100 * removed the field isMapped from register definition,
5102 ** Several functions have been removed from various sources:
5103 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5104 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5105 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5106 pic16_assignRelocatableRegisters
5108 ** others have been introduced:
5109 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5110 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5112 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5114 * support/scripts/inc2h.pl: changed definition of BIT_AT
5115 to emit 'sbit at' instead of 'bit at'. This was a request.
5117 PIC16 port related preliminary changes:
5118 * gen.c: prefixed function popRegFromString with
5119 pic16_ and all references to it corrected
5120 * pcode.c: all pic16_pc_* hardware registers prefixed
5121 with underscore (_),
5122 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5123 * ralloc.c: newReg(): when register is REG_SFR then
5124 set address to rIdx,
5125 pic16_allocProcessorRegister(): marks register wasUsed=0
5126 pic16_writeUsedRegs(): added a call to assign processor
5127 registers via pic16_assignFixedRegisters
5129 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5131 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5132 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5133 variables in unused register banks. Also the SSEG is placed
5134 wherever there is enough space for it, and IDATA can be anywhere
5135 in internal RAM. For now compile using -Wl-Y[stack_size].
5136 The mem file is different for this option as well, since it
5137 makes no sense of talking about DSEG lenght.
5139 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5141 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5142 in certain cases, e.g. when ROM assignment, patch provided
5143 from Albert den Haan.
5145 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6051 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6053 Fixed bug #621531 (const & volatile confusion in the type chain).
6054 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

6147 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
6148 fetching of the pointer
6149 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
6150 copied from genNearPointerSet()
6151 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
6152 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
6153 If they pop r0/r1 they must be called in the opposite order than aopOp().
6154 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
6155 (resp. --stack-auto), prepared for --xstack

6166 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
6168 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6169 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6170 type for bits was changed. It resulted in bit variables becoming
6171 global, which is not permitted in PIC 14 assembly output.
6173 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6175 * doc/sdccman.lyx: various additions and updates. Rearranged sections

6186 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6188 A few small changes that speed up the peephole optimizer.
6192 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6194 Try to make the peephole optimizer smarter by maintaining
6195 an association between the assembly source code and the
6196 iCodes that originated them. Put this information to use
6197 with a new peephole rule condition "notVolatile" so that
6198 the rules can be aggressive yet still safe.
6203 * src/mcs51/peeph.def
6205 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6209 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6210 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6211 if the left or right operand symbols have the accuse flag set.
6213 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6215 Changed the type of the result of the ! (NOT) operator to char;
6216 previously it returned the same type as the source. This allows
6217 us to eliminate all the genFloatNot functions (all of its target
6218 implementations were very buggy) since !float can use the same
6221 * src/SDCCicode.c (ast2iCode): ! returns char
6222 * src/mcs51/gen.c (genNot, genNotFloat),
6223 * src/ds390/gen.c (genNot, genNotFloat),
6224 * src/z80/gen.c (genNot, genNotFloat),
6225 * src/pic/gen.c (genNot, genNotFloat),

6228 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
6230 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6231 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6232 during interrupts. Ensure WSAVE is located at a shared bank address.
6233 2. Fixed page selection in some places
6234 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6235 the registers name strings.
6236 4. Fixed "signed / unsigned compare" compiler warnings.
6237 5. The PIC port manages its own allocation of the general purpose
6238 registers, but makes no attempt to reuse them. As a result when
6239 compiling it soon runs out of general purpose registers. Some
6240 additional code was added to the files pcode.c and device.c to walk
6241 through the function call tree and rename the registers so that they
6251 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6252 genPlus() & genMinus() when the result is the same as left or right
6254 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6258 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6260 Made bitfield a distinct type from bit so that bitfields
6261 convert as per ANSI C and bits retain their traditional
6262 boolean style behaviour. Implemented bitfield support in
6270 * src/ds390/gen.c: bit v bitfield split
6271 * src/z80/gen.c: New support for bitfields
6272 * support/regression/tests/bitfields.c: reenabled z80,
6275 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6277 Rules 246.x, 247.x relate to bitfields, the others speed up
6278 access to xdata mapped I/O devices.
6280 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6282 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6284 Cleaned up genPackBits and genUnpackBits and added two helper
6285 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6286 for literal assignments in genPackBits (thanks to Frieder for
6292 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6294 Fixed bug #748310 (pointer to function type mishandled when the
6295 function name is omitted). Also fixed a SIGSEGV when a function
6296 attribute (reentrant, etc) is used on a non-function or on a
6297 function but misplaced before the parameter list.
6299 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6301 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
6302 * support/Util/SDCCerr.h,
6303 * support/Util/SDCCerr.c: Added func attr misuse error msg
6305 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
6307 Fixed bug #787649 by anonymous
6308 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr

6324 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6326 Made the constant following the "interrupt" keyword optional. If
6327 omitted, the function will not automatically be given an entry
6328 in the interrupt vector table (similar to #pragma NOIV, but
6329 less syntacticly kludgy). The interrupt number is also now
6330 range checked. Also fixed a bug in the high order bit example

6344 * src/SDCCicode.c (operandOperation): rewritten some ops
6345 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
6346 * src/SDCCsymt.c (computeType): literals are handled the same way as any
6348 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
6349 be re-activated by defining REDUCE_LITERALS)
6350 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
6351 unsigned, but are signed by default
6352 * src/SDCCval.c (constVal): rearranged
6353 * src/SDCCval.c (valMod): preliminary fix
6354 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6396 constants are unsigned; added recognition of "u" flag for unsigned
6397 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
6398 * src/SDCCval.c (valDiv, valMod): fixed signdness
6399 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
6400 signedness of modulo, left and right shift

6860 added if/endif conditional macros to remove options help
6861 messages from optionsTable when a port is not configured, added
6862 support for the PIc16 port in the ports table, when executing
6863 the compiler with no port specified on command line, a default
6864 port is selected with the new macro DEFAULT_PORT which is
6865 defined in port.h, in setDefaultOptions() linkOptions is removed
6866 from initialization assignment, since now it is a set,
6867 parseCmdLine uses setParseWithComma for linkOptions, in
6868 linkEdit() linkOptions are accessed with new function indexSet()
6869 which returns the i'th item of a set variable. See SDCCset.c, in
6870 linkEdit() when calling buildCmdLine(), added linkOptions as
6871 last argument. Now users can pass arguments to gplink via the
6872 -Wl option, main() uses pic16glue() to glue up pic16 programs

6886 gpasm complaining and test the linkage with gplink, _linkCmd and
6887 _asmCmd changed to be more gplink and gpasm friendly
6888 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6889 produced an error when parsed, peep rule 12 is added to utilize
6890 movff, but it is commented out since the pCode does not support
6891 yet a command with 2 address arguments
6893 2003-05-18 <johan AT balder>
6895 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6922 2003-05-11 Borut Razem <borut.razem AT siol.net>
6924 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

7956 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7958 * in \sdcc\as\mcs51\ changed these files in order to create an
7959 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7960 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7961 following files to include the previous two files: aslink.dsp,
7962 Makefile.aslink, Makefile.bcc, and Makefile.in.
7964 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7965 .adb instead of .cdb
7967 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7969 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7970 value from option --iram-size.
7972 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7974 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7977 2002-09-18 <wiml AT hhhh.org>
7979 * SDCClrange.h: exposed setFromRange() and setToRange()
7980 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7981 packRegsForAccUse() (bug 542397)
7982 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7983 multiple times and emitting the fetch operations more than once
7984 added aopGetUsesAcc() function to allow binary operators to
7985 fetch their operands in the correct order; made genMinus() emit
7986 compact code for X = LITERAL - Y
7988 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7989 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7990 sprintf() in line 1267.
7992 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7993 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7996 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7997 Changes to aslink (All the changes are marked with 'JCF'):
7999 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8002 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8003 area BSEG. Also moves, if possible, the DATA area down into the internal
8004 ram so more space is available.
8006 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8009 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8010 not bytes. Function summary() which creates a memory usage summary
8011 file with extension .mem. Reports of overlaping stack and small stack
8012 size. If the space for the stack is less than 16 bytes aslink trows a
8015 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8016 the 8051. Option 'y' for memory summary output file.
8018 Changes to sdcc (All the changes are marked with 'JCF'):
8020 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8022 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8023 overlaying area for it (uses RegBankUsed[4]).
8025 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8026 bank zero as used by default. By default aslink locates the stack
8027 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8028 the creation of the .mem file. Delegates the allocation of data area
8029 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8030 the begining of the stack area to aslink.
8032 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8033 glue() in SDCCglue.c creates an area for it.
8035 2002-09-03 Borut Razem <borut.razem AT siol.net>
8036 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8037 sdcc/src/pic/glue.c:
8038 introduced atexit() handler for teporay files removal in case of
8039 errors, assertions, ...
8041 2002-08-29 Borut Razem <borut.razem AT siol.net>
8042 * sdcc/support/cpp2/auto-host_vc_in.h:
8043 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8044 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8045 Maybe there is a similar problem with BORLANDC? It should be checked!
8047 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8048 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8049 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8050 was not executed, and the compiler (cl) launched a warning:
8051 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8053 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8054 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8056 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8057 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8059 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8060 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8061 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8062 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8063 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8064 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8065 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8066 - added Release configuration in VS projects
8067 - review of compiler an linker options
8068 - VC .exe files are generated in bin_vc directory, not to interfere
8069 with binaries generated from other projects (cygwin, mingw, bcc ...)
8071 * sdcc/src/yacc.dsp: added
8073 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8074 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8075 and insert the version number definitions from .version
8077 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8079 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8080 added - genarate auto-host.h using auto-host_vc_in.h as template
8083 removed from CVS, generated automatically
8085 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8086 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8088 2002-08-11 Borut Razem <borut.razem AT siol.net>
8089 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8091 2002-08-10 Borut Razem <borut.razem AT siol.net>
8092 * src/SDCCmain.c (main):
8093 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8094 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8095 The consequence was that some temporary files were not removed.
8098 unification of code in functions tempfilename() and tempfile():
8099 function tempnam() is defined in Visual Studio 6.0 and .NET
8101 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8103 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8104 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8105 - removed compiler command line option /WX: Treats all warnings as errors
8106 - update a list of source files, included into the project
8108 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8109 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8110 changed project type to Generic Project so that can be correcly converted to VS.NET project
8112 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8114 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8116 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8118 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8119 added return 0 statements after assert() to make compiler happy
8121 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8122 added newline in the def file to keep MSC compiler satisfied
8124 * sdcc/src/z80/gen.c:
8125 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8126 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8127 - solved MSC error in function aopDump()
8129 * sdcc_vc.h: define PREFIX as "\\sdcc"
8131 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8132 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

8138 singly-used registers optimized away)
8140 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
8142 * 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.

8180 Added -p option. Allows port dependent processor to be specified.
8183 Initialized the new field char *Processor field to NULL in all ports
8186 Compiler generated registers for interrupt context saving
8187 were not getting allocated.
8189 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8192 Fixed left shift. Will promote the left side of a left shift
8193 if a) left shifting more than size of operand or b) when assigned
8194 to something size > size of left side
8196 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8198 tons of changes. Register allocation has been
8199 rewritten. Added customization for the various PICs. Flow

8307 Previous fix was not good. basic blocks that have "break" or "return" are
8308 not really partof a loop , but live ranges used in these blocks should
8309 be live thru the entire loop, so set partOfLoop but don't add them to
8312 2002-02-21 <johan AT FRIJA>
8314 * src/SDCCcse.c: fixed bug #514308
8316 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
