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

1240 * (genNearPointer[GS]et): enforce reloading of FSR0 (was still
1241 used uninitialized in some cases)

1243 copy the third byte from the int -- now assumes 0x80 (data memory)
1244 * src/pic16/genarith.c (pic16_genPlus): fixed bug when swapping

1285 pic16_framepnt_*, pic16_stack_*, pic1_frame_* pointer variables to
1286 access stack and frame pointers. They are initially assigned to
1287 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
1288 accessing SFRs. Updated all occurences of modification of stack or
1289 frame pointer in gen.c and pcode.c,
1290 * src/pic16/ralloc.c (serialRegAssign): fixed two bugs with
1291 assigning of a literal value to pointers,

1334 from Raphael Neider,
1335 * src/pic16/pcode.c (pic16_newpCodeOpLit): removed casting to char

1595 generated for switch statements. For now you need to set the
1596 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1597 Now 4 algorithms for mcs51 jumptable generation are used:
1598 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

1632 * added libc directory. The current version of LibC contains string
1633 functions, ctype functions and macros and some functions of the
1634 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1635 be extensively tested in the future. Standard disclaimer here.

1649 * (genCmp): experimental code for new genCmp which uses PIC18's
1650 special compare&skip instructions. Initial tests fail some times
1651 with variables grater than 1 byte in size, so new code is disabled,
1652 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1654 * (genCast): began a fix to optimize the casting of a bit to another
1655 bit, now assigning a bitfield to another bitfield will fail, sorry,

1664 and 1 for banking instruction,
1665 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1666 caused stop processing pCodes after a inline assembly block,
1667 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

1669 registers when it shouldn't,
1670 * src/pic16/ralloc.c (allocReg): add preliminary support for
1671 supporting a limited set of temporary registers,
1673 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4681 loaded with the linker search paths (-L arguments) and the libraries
4682 to be linked with the current source (-l arguments). Changes
4683 currently will affect only the pic16 port.
4684 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4685 include path the port specific paths and port specific libraries,
4686 * gplink command now contains the $3 argument,
4687 * src/pic16/device.h,
4688 * src/pic16/device.c,: structure PIC_device is made public and

4704 Documenting changes from previous commits.
4705 * configure.in (version 1.56),
4706 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4707 when generating output files to configure the pic16 library,
4708 but now I've commented it out, since gputils aren't installed in the
4709 SF compile farm, so library won't compile
4711 * device/lib/Makefile.in (version 1.56): initially I've added in
4712 target 'all' the prerequestive 'model-pic16' so it compiled the
4713 pic16 library, but now I've commented it out for the same reasons
4715 * added targets 'model-pic16' and 'objects-pic16' to compile the
4717 * added target 'port-specific-objects-pic16' to handle the
4718 generated libraries and copy them into the build/ directory
4719 * added target 'clean-intermediate-pic16' to clean intermediate
4720 files into pic16 directory
4721 * in target 'installdirs' added line to create directory pic16 in

4742 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4743 option so that it actually works. Made it specific to the z80, since
4744 the gbz80 doesn't have these kinds of I/O ports.
4746 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4748 * device/include/z180.h,

4772 via literal number. The symbol is placed in the corresponding
4773 position of the data ram
4774 * (pic16_dump_section): relocatable and absolute uninitialized
4775 data are now emitted in sorted order to reduce section naming,
4776 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4777 weren't marked as being in the access bank,

4970 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4972 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4973 (default behaviour).
4975 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4977 A python script to validate compiler diagnostic messages. It can be
4978 used to verify that sdcc complains about bad c source code and

5001 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5003 * sdcc.spec: updated
5004 * device/include/Makefile.in: don't install CVS directories

5006 * doc/Makefile: fixed install, added local_icons
5007 * sim/ucsim/gui.src/Makefile.in: fixed an old typo

5012 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5014 PIC16 port related changes:
5015 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5016 added variable stackPos,
5018 * gen.c: genCall, assignResultValue: added support for
5019 pushing/retrieving function parameters to/from stack,
5020 genFunction,genEndFunction: setup stack frame for the
5022 genAddrOf: will be changed according to bug 863624
5024 * added files genutils.c and genutils.h which contain gen*
5025 debugged and optimised functions extracted from gen.c
5027 * glue.c: added variable 'externs' which holds extern symbols,
5028 pic16emitRegularMap: is modified to properly handle relocatable
5029 symbols under the new scheme,
5030 pic16createInterruptVect: is modified
5031 pic16printPublics: is modified to emit 'global' assembler directives,
5032 added pic16_printExterns to print extern symbols,
5033 pic16glue: initializes stack/frame pointer in the beginning of
5034 the assembly output. Temporary hack, will be corrected later,
5035 because gplink yet does not support stack and SDCC does not
5036 yet support a type of crt0.o object to create the final binary.
5038 * Removed many lines that contain 8051 legacy code.
5039 * The code is finally placed under a 'code' directive.
5040 * Added port specific options.
5042 * _process_pragma: simplified since now we do not need *special*
5043 include file to define SFR registers. But a separate header
5044 will be needed. This will be developed later.
5045 * _pic16_parseOptions: added, parses port specific options:
5046 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5047 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5048 --preplace-udata-with=
5050 * _pic16_setDefaultOptions: modified to initialize section names,
5051 but hack is temporarly out of order since it needs improvement.
5052 * _pic16_genAssemblerPreamble: configuration words are emitted by
5053 their address instead of their name. This part is incomplete and
5054 supports only the 18Fxx2 devices. Other devices will emit an error
5055 during assembly since they do not contain the same set of config
5057 * _pic16_genIVT: is modified,
5059 * pcode.c: added definitions for some hardware registers that are needed
5061 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5062 All PCI entries are updated. Now LFSR is supported.
5063 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5064 * added pic16_newpCodeOpLit2 to support instructions with
5065 two literal arguments
5066 * pic16_pCode2str: corrected code that emits assembler instructions
5067 with two literal operands and those that have an access bit modifier
5068 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5069 this fixes a bug which caused some labels to be lost, when an
5070 assembler directive was added, i.e. banksel,
5071 * pic16_FixRegisterBanking: improved logic that causes the insertion
5073 * InlineFunction: functions that are called once, are not any more
5074 inlined. This can be a port option in the future,
5076 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5078 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5079 hold the corresponding uninitialized symbols,
5080 * pic16_allocProcessorRegister: registers have explicit marked the
5082 * pic16_allocInternalRegister: registers are explicit marked as
5084 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5085 processing list, so bit registers were lost,
5088 * ralloc.h: added field 'accessBank' and original symbol operand
5089 in register definition,
5090 * removed the field isMapped from register definition,
5092 ** Several functions have been removed from various sources:
5093 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5094 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5095 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5096 pic16_assignRelocatableRegisters
5098 ** others have been introduced:
5099 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5100 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5102 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5104 * support/scripts/inc2h.pl: changed definition of BIT_AT
5105 to emit 'sbit at' instead of 'bit at'. This was a request.
5107 PIC16 port related preliminary changes:
5108 * gen.c: prefixed function popRegFromString with
5109 pic16_ and all references to it corrected
5110 * pcode.c: all pic16_pc_* hardware registers prefixed
5111 with underscore (_),
5112 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5113 * ralloc.c: newReg(): when register is REG_SFR then
5114 set address to rIdx,
5115 pic16_allocProcessorRegister(): marks register wasUsed=0
5116 pic16_writeUsedRegs(): added a call to assign processor
5117 registers via pic16_assignFixedRegisters
5119 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5121 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5122 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5123 variables in unused register banks. Also the SSEG is placed
5124 wherever there is enough space for it, and IDATA can be anywhere
5125 in internal RAM. For now compile using -Wl-Y[stack_size].
5126 The mem file is different for this option as well, since it
5127 makes no sense of talking about DSEG lenght.
5129 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5131 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5132 in certain cases, e.g. when ROM assignment, patch provided
5133 from Albert den Haan.
5135 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6138 fetching of the pointer
6139 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
6140 copied from genNearPointerSet()
6141 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
6142 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

6158 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6159 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6160 type for bits was changed. It resulted in bit variables becoming
6161 global, which is not permitted in PIC 14 assembly output.
6163 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6165 * doc/sdccman.lyx: various additions and updates. Rearranged sections

6176 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6178 A few small changes that speed up the peephole optimizer.
6182 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6184 Try to make the peephole optimizer smarter by maintaining
6185 an association between the assembly source code and the
6186 iCodes that originated them. Put this information to use
6187 with a new peephole rule condition "notVolatile" so that
6188 the rules can be aggressive yet still safe.
6193 * src/mcs51/peeph.def
6195 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6199 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6200 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6201 if the left or right operand symbols have the accuse flag set.
6203 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6205 Changed the type of the result of the ! (NOT) operator to char;
6206 previously it returned the same type as the source. This allows
6207 us to eliminate all the genFloatNot functions (all of its target
6208 implementations were very buggy) since !float can use the same
6211 * src/SDCCicode.c (ast2iCode): ! returns char
6212 * src/mcs51/gen.c (genNot, genNotFloat),
6213 * src/ds390/gen.c (genNot, genNotFloat),
6214 * src/z80/gen.c (genNot, genNotFloat),
6215 * src/pic/gen.c (genNot, genNotFloat),
6216 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
6218 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
6220 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6221 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6222 during interrupts. Ensure WSAVE is located at a shared bank address.
6223 2. Fixed page selection in some places
6224 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6225 the registers name strings.
6226 4. Fixed "signed / unsigned compare" compiler warnings.
6227 5. The PIC port manages its own allocation of the general purpose
6228 registers, but makes no attempt to reuse them. As a result when
6229 compiling it soon runs out of general purpose registers. Some
6230 additional code was added to the files pcode.c and device.c to walk
6231 through the function call tree and rename the registers so that they
6241 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6242 genPlus() & genMinus() when the result is the same as left or right

6248 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6250 Made bitfield a distinct type from bit so that bitfields
6251 convert as per ANSI C and bits retain their traditional
6252 boolean style behaviour. Implemented bitfield support in
6260 * src/ds390/gen.c: bit v bitfield split
6261 * src/z80/gen.c: New support for bitfields
6262 * support/regression/tests/bitfields.c: reenabled z80,
6265 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6267 Rules 246.x, 247.x relate to bitfields, the others speed up
6268 access to xdata mapped I/O devices.
6270 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6272 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6274 Cleaned up genPackBits and genUnpackBits and added two helper
6275 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6276 for literal assignments in genPackBits (thanks to Frieder for
6282 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6284 Fixed bug #748310 (pointer to function type mishandled when the
6285 function name is omitted). Also fixed a SIGSEGV when a function
6286 attribute (reentrant, etc) is used on a non-function or on a
6287 function but misplaced before the parameter list.
6289 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6291 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
6292 * support/Util/SDCCerr.h,
6293 * support/Util/SDCCerr.c: Added func attr misuse error msg

6314 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6316 Made the constant following the "interrupt" keyword optional. If
6317 omitted, the function will not automatically be given an entry
6318 in the interrupt vector table (similar to #pragma NOIV, but
6319 less syntacticly kludgy). The interrupt number is also now
6320 range checked. Also fixed a bug in the high order bit example

6331 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
6333 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
6334 * src/SDCCicode.c (operandOperation): rewritten some ops
6335 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
6336 * src/SDCCsymt.c (computeType): literals are handled the same way as any
6338 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
6339 be re-activated by defining REDUCE_LITERALS)
6340 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
6341 unsigned, but are signed by default
6342 * src/SDCCval.c (constVal): rearranged
6343 * src/SDCCval.c (valMod): preliminary fix
6344 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6850 added if/endif conditional macros to remove options help
6851 messages from optionsTable when a port is not configured, added
6852 support for the PIc16 port in the ports table, when executing
6853 the compiler with no port specified on command line, a default
6854 port is selected with the new macro DEFAULT_PORT which is
6855 defined in port.h, in setDefaultOptions() linkOptions is removed
6856 from initialization assignment, since now it is a set,
6857 parseCmdLine uses setParseWithComma for linkOptions, in
6858 linkEdit() linkOptions are accessed with new function indexSet()
6859 which returns the i'th item of a set variable. See SDCCset.c, in
6860 linkEdit() when calling buildCmdLine(), added linkOptions as
6861 last argument. Now users can pass arguments to gplink via the
6862 -Wl option, main() uses pic16glue() to glue up pic16 programs

6876 gpasm complaining and test the linkage with gplink, _linkCmd and
6877 _asmCmd changed to be more gplink and gpasm friendly
6878 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6879 produced an error when parsed, peep rule 12 is added to utilize
6880 movff, but it is commented out since the pCode does not support
6881 yet a command with 2 address arguments
6883 2003-05-18 <johan AT balder>
6885 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6912 2003-05-11 Borut Razem <borut.razem AT siol.net>
6914 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

7903 2003-01-07 <johan AT balder>
7905 * src/SDCCast.c (decorateType): fixed bug #600035
7907 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>

7918 2003-01-06 <johan AT balder>
7920 * src/SDCCicode.c: fixed array add
7922 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
7923 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
7924 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
7926 2003-01-04 <johan AT balder>
7928 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7930 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7931 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
7933 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
7934 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

7940 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
7941 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
7943 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7944 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7946 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7948 * in \sdcc\as\mcs51\ changed these files in order to create an
7949 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7950 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7951 following files to include the previous two files: aslink.dsp,
7952 Makefile.aslink, Makefile.bcc, and Makefile.in.
7954 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7955 .adb instead of .cdb
7957 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7959 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7960 value from option --iram-size.
7962 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7964 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7967 2002-09-18 <wiml AT hhhh.org>
7969 * SDCClrange.h: exposed setFromRange() and setToRange()
7970 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7971 packRegsForAccUse() (bug 542397)
7972 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7973 multiple times and emitting the fetch operations more than once
7974 added aopGetUsesAcc() function to allow binary operators to
7975 fetch their operands in the correct order; made genMinus() emit
7976 compact code for X = LITERAL - Y
7978 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7979 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7980 sprintf() in line 1267.
7982 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7983 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7986 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7987 Changes to aslink (All the changes are marked with 'JCF'):
7989 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7992 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7993 area BSEG. Also moves, if possible, the DATA area down into the internal
7994 ram so more space is available.
7996 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7999 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8000 not bytes. Function summary() which creates a memory usage summary
8001 file with extension .mem. Reports of overlaping stack and small stack
8002 size. If the space for the stack is less than 16 bytes aslink trows a
8005 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8006 the 8051. Option 'y' for memory summary output file.
8008 Changes to sdcc (All the changes are marked with 'JCF'):
8010 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8012 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8013 overlaying area for it (uses RegBankUsed[4]).
8015 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8016 bank zero as used by default. By default aslink locates the stack
8017 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8018 the creation of the .mem file. Delegates the allocation of data area
8019 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8020 the begining of the stack area to aslink.
8022 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8023 glue() in SDCCglue.c creates an area for it.
8025 2002-09-03 Borut Razem <borut.razem AT siol.net>
8026 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8027 sdcc/src/pic/glue.c:
8028 introduced atexit() handler for teporay files removal in case of
8029 errors, assertions, ...
8031 2002-08-29 Borut Razem <borut.razem AT siol.net>
8032 * sdcc/support/cpp2/auto-host_vc_in.h:
8033 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8034 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8035 Maybe there is a similar problem with BORLANDC? It should be checked!
8037 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8038 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8039 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8040 was not executed, and the compiler (cl) launched a warning:
8041 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8043 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8044 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8046 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8047 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8049 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8050 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8051 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8052 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8053 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8054 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8055 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8056 - added Release configuration in VS projects
8057 - review of compiler an linker options
8058 - VC .exe files are generated in bin_vc directory, not to interfere
8059 with binaries generated from other projects (cygwin, mingw, bcc ...)
8061 * sdcc/src/yacc.dsp: added
8063 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8064 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8065 and insert the version number definitions from .version
8067 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8069 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8070 added - genarate auto-host.h using auto-host_vc_in.h as template
8073 removed from CVS, generated automatically
8075 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8076 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8078 2002-08-11 Borut Razem <borut.razem AT siol.net>
8079 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8081 2002-08-10 Borut Razem <borut.razem AT siol.net>
8082 * src/SDCCmain.c (main):
8083 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8084 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8085 The consequence was that some temporary files were not removed.
8088 unification of code in functions tempfilename() and tempfile():
8089 function tempnam() is defined in Visual Studio 6.0 and .NET
8091 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8093 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8094 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8095 - removed compiler command line option /WX: Treats all warnings as errors
8096 - update a list of source files, included into the project
8098 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8099 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8100 changed project type to Generic Project so that can be correcly converted to VS.NET project
8102 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8104 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8106 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8108 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8109 added return 0 statements after assert() to make compiler happy
8111 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8112 added newline in the def file to keep MSC compiler satisfied
8114 * sdcc/src/z80/gen.c:
8115 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8116 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8117 - solved MSC error in function aopDump()
8119 * sdcc_vc.h: define PREFIX as "\\sdcc"
8121 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8122 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
8124 2002-06-22 Scott Dattalo <scott AT dattalo.com>
8125 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
8126 - Rewrote the register banking algorithm.
8127 - Added pCode live-range analysis to registers (for now, only non-used and
8128 singly-used registers optimized away)
8130 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
8132 * 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.
8134 2002-05-10 Scott Dattalo <scott AT dattalo.com>
8135 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
8137 2002-04-22 Michael Hope <michaelh AT vroom>

8157 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
8159 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
8161 2002-03-28 Johan Knol <johan AT balder>
8163 * src/SDCCval.c: fixed bug #532436
8165 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8167 Added "char *Processor" field to the port structure.
8170 Added -p option. Allows port dependent processor to be specified.
8173 Initialized the new field char *Processor field to NULL in all ports
8176 Compiler generated registers for interrupt context saving
8177 were not getting allocated.
8179 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8182 Fixed left shift. Will promote the left side of a left shift
8183 if a) left shifting more than size of operand or b) when assigned
8184 to something size > size of left side
8186 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8188 tons of changes. Register allocation has been
8189 rewritten. Added customization for the various PICs. Flow
8190 analysis is restructured. ...
8196 Added. device.c is a PIC port hack to accomodate variations
8199 2002-03-13 Michael Hope <michaelh AT vroom>
8201 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
8203 2002-03-04 johanknol <johanknol AT manik>
8205 * /src/SDCCval.c: fixed
8207 const unsigned char arr[][2] = { { 0, 1 } };
8208 t18.c:1: error: Initializer element is not constant
8210 2002-03-04 bela <bela AT manik>
8212 * /device/include/mcs51reg.h:
8213 ds89c420 register definition update
8215 2002-03-03 <johan AT FRIJA>

8294 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
8296 * sdcc/src/SDCCloop.c:
8297 Previous fix was not good. basic blocks that have "break" or "return" are
8298 not really partof a loop , but live ranges used in these blocks should
8299 be live thru the entire loop, so set partOfLoop but don't add them to
8302 2002-02-21 <johan AT FRIJA>
8304 * src/SDCCcse.c: fixed bug #514308
8306 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
