1904 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
1905 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1906 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1907 always available in leading double underscore form. The C99 support is

1988 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1990 * device/lib/printf_large.c: removed inline assembly for portability and
1991 readability. Use printf_fast if speed or size are more important.
1992 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1993 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1995 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1997 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1998 prevent compiler warning
2000 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2002 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2003 moved to level 0 and declared as static. Also they are explicit
2004 placed in access bank. This was necessery because some times they
2005 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2006 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2007 optimizations. Currently only compare to unsigned char is implemented,
2008 * src/pic16/gen.c: added fReturnIdx array,
2009 * (struct resolvedIfx) is moved to gen.h and made public,
2010 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2011 * (aopForSym): added an optimization to directly store in stack of
2012 the operand of a SEND iCode,
2013 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2014 but as registers instead (AOP_REG) using the fReturnIdx array,
2015 * (pic16_freeAsmop): remove the freed register from the
2016 _G.sregsAlloc field,
2017 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2018 a compare of 'WREG',
2019 * (pic16_popGetTempRegCond): changed function prototype, now
2020 function takes also a bitVector argument v which holds the current
2021 set of registers that are allocated for stack access by aopForSym,
2022 registers allocated in aopForSym for accessing stack symbols are not
2023 any more part of the functions usedRegs field,
2024 * (genCall): some times aopOp is called for a stack variable to be
2025 send, aopForSym might perform the push, if this is true make sure
2026 that genCall doesn't push the variable twice by testing _G.resDirect,
2027 * (genFunction): changed testing for unspecified interrupt number
2028 from 256 to INTNO_UNSPEC,
2029 * modified selection scheme of frame pointer generation. Previously
2030 if function did use local registers a frame pointer was generated,
2031 now a frame pointer is generated only if function has arguments
2032 (that need PLUSW2 register access), or has stack arguments, or the
2033 compiler is not instructed to omit the frame pointer,
2034 * (genEndFunction): before restoring local registers that were saved
2035 in the function preamble, also restore the registers that *might*
2036 have been allocated for stack access,
2037 * (genRet): removed some old comments,
2038 * (genCmp, the active (RN's) version): added a call to the
2039 pic16_genCmp_special function to perform the compare with a more
2040 robust and optimized way,
2041 * (genInline): a feature has been added in inline code generation,
2042 which allows a wildcard variable substitution when writing inline
2043 assembly. Code is incomplete and experimental therefore undocumented,
2044 * (genCast): changed order of aopOp for result and right to allow
2045 aopForSym to directly load the result if possible,
2046 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2047 perform an optimized compare on some selected special occasions,
2048 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2049 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2050 generate an IVT any more,
2051 * src/pic16/main.c (pic16_optionsTable): added command line option
2053 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2054 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2056 * src/pic16/NOTES: Raphael Neider added in list of active developers
2057 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2058 jumptable_end to prevent bug #,
2059 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2060 inCond and outCond fields,
2061 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2062 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2063 turn off register spilling,
2064 * (packRegsForOneUse): synced with other ports' versions although it
2065 is not used currently,
2066 * (pic16_packRegisters): added an optimization while reading
2067 structure bitfields, some registers may be saved (malloc code is
2068 decreased by 80 bytes)
2070 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2072 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2073 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2074 this can be optimized more?
2076 2005-03-10 Raphael Neider <rneider AT web.de>
2078 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2079 genNearPointerGet): (hopefully) fixed access to bitfields via
2080 pointers (p->bitN = x; and x = p->bitN; failed)

2714 Adding support for replacing ljmps with sjmps in jumptables
2715 generated for switch statements. For now you need to set the
2716 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2717 Now 4 algorithms for mcs51 jumptable generation are used:
2718 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2719 addresses loaded pc-relative for up to 112 cases and stack-pushing
2720 target addresses loaded with offset from dptr for up to 256 cases.

2750 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2752 * added libc directory. The current version of LibC contains string
2753 functions, ctype functions and macros and some functions of the
2754 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2755 be extensively tested in the future. Standard disclaimer here.
2756 Library is not automatically build yet. But one can build it by
2757 invoking 'make' inside the libc directory.

2768 * (pic16_storeForReturn): optimized return of 0,
2769 * (genCmp): experimental code for new genCmp which uses PIC18's
2770 special compare&skip instructions. Initial tests fail some times
2771 with variables grater than 1 byte in size, so new code is disabled,
2772 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2774 * (genCast): began a fix to optimize the casting of a bit to another
2775 bit, now assigning a bitfield to another bitfield will fail, sorry,

2789 registers when it shouldn't,
2790 * src/pic16/ralloc.c (allocReg): add preliminary support for
2791 supporting a limited set of temporary registers,
2793 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2795 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,

2799 (genFunction): optimize RECEIVE iCodes in reentrant functions
2801 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5683 * ChangeLog: changed "@" to " AT " in hopes of reducing spam and
5684 virus/worm forged address usage.
5686 2004-01-27 Bernhard Held <bernhard AT bernhardheld.de>
5688 Fixed promotion, it should be done on AST level:
5689 * src/SDCCast.c (addCast): added promotion to int

5704 * support/regression/generate-cases.py (main): Changed from inline
5707 * doc/Makefile (install): Changed to depth first to get rid of
5708 missing directory install warning.
5710 * as/Makefile (install-doc): Made work on Mac.
5712 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
5714 * src/SDCCast.c: added an additional type flow in decorateType() of
5715 opposite direction, see feature request #860006; it's enabled at runtime
5716 by setting the environment variable SDCC_NEWTYPEFLOW
5717 * src/SDCCast.h: changed prototype of decorateType()
5718 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
5719 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
5720 'char' to 'int' can be omitted, if both operands are 'unsigned char';
5721 see feature request #877103
5722 * src/SDCCval.c: updated call of decorateType()
5723 (valBitwise): fixed bug #882876
5724 (valMinus): added promotion
5725 (valLogicAndOr): result is unsigned
5726 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
5727 * src/SDCCsymt.c (computeType),

5750 * src/pic/ralloc.h: applied patch from Slade Rich;
5751 added support for multiple code pages and multiple RAM banks on the
5752 PIC 14 port. The ASM files now no longer simply assume all the
5753 code / RAM are in the same page / bank. This means the linker can
5754 safely allocate code/RAM of separate ASM files to different pages/banks.
5755 * doc/sdccman.lyx: added Slade's tips
5756 * src/mcs51/peeph.def: fixed bug #880768

5798 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5800 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5801 loaded with the linker search paths (-L arguments) and the libraries
5802 to be linked with the current source (-l arguments). Changes
5803 currently will affect only the pic16 port.
5804 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5805 include path the port specific paths and port specific libraries,
5806 * gplink command now contains the $3 argument,
5807 * src/pic16/device.h,
5808 * src/pic16/device.c,: structure PIC_device is made public and
5809 renamed to PIC16_device, the same for variable Pics which is renamed

5822 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
5824 Documenting changes from previous commits.
5825 * configure.in (version 1.56),
5826 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5827 when generating output files to configure the pic16 library,
5828 but now I've commented it out, since gputils aren't installed in the
5829 SF compile farm, so library won't compile
5831 * device/lib/Makefile.in (version 1.56): initially I've added in
5832 target 'all' the prerequestive 'model-pic16' so it compiled the
5833 pic16 library, but now I've commented it out for the same reasons
5835 * added targets 'model-pic16' and 'objects-pic16' to compile the
5837 * added target 'port-specific-objects-pic16' to handle the
5838 generated libraries and copy them into the build/ directory
5839 * added target 'clean-intermediate-pic16' to clean intermediate
5840 files into pic16 directory
5841 * in target 'installdirs' added line to create directory pic16 in
5842 the installation path
5844 * device/include/Makefile.in (version 1.11): in target 'install'
5845 added lines to copy all header files to installation path,
5846 * in target 'installdirs' added line create directory for pic16
5847 headers in the installation path

5862 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5863 option so that it actually works. Made it specific to the z80, since
5864 the gbz80 doesn't have these kinds of I/O ports.
5866 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5868 * device/include/z180.h,

5892 via literal number. The symbol is placed in the corresponding
5893 position of the data ram
5894 * (pic16_dump_section): relocatable and absolute uninitialized
5895 data are now emitted in sorted order to reduce section naming,
5896 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5897 weren't marked as being in the access bank,
5899 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5901 Added portion of GNU PIC Library under the directory
5902 device/include/pic16 and device/lib/pic16. These files
5903 contain the declarations of SFRs for the PIC18Fxx2 devices.
5904 The directory is initialized via configure from toplevel.

5934 all over. Telling LaTeX to be less strict with word spacing
5935 to better keep the right margin. Changed some notes about
5936 maintainance of the ports in section 3.2.1 - is it OK like this?
5938 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5978 * src/pic16/peeph.def: all peepholes with movff are commented out,
5979 because there is a problem in the pcode peep optimizer,
5980 * src/pic16/ralloc.c: the register allocator can now reuse local

6132 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6134 PIC16 port related changes:
6135 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6136 added variable stackPos,
6138 * gen.c: genCall, assignResultValue: added support for
6139 pushing/retrieving function parameters to/from stack,
6140 genFunction,genEndFunction: setup stack frame for the
6142 genAddrOf: will be changed according to bug 863624
6144 * added files genutils.c and genutils.h which contain gen*
6145 debugged and optimised functions extracted from gen.c
6147 * glue.c: added variable 'externs' which holds extern symbols,
6148 pic16emitRegularMap: is modified to properly handle relocatable
6149 symbols under the new scheme,
6150 pic16createInterruptVect: is modified
6151 pic16printPublics: is modified to emit 'global' assembler directives,
6152 added pic16_printExterns to print extern symbols,
6153 pic16glue: initializes stack/frame pointer in the beginning of
6154 the assembly output. Temporary hack, will be corrected later,
6155 because gplink yet does not support stack and SDCC does not
6156 yet support a type of crt0.o object to create the final binary.
6158 * Removed many lines that contain 8051 legacy code.
6159 * The code is finally placed under a 'code' directive.
6160 * Added port specific options.
6162 * _process_pragma: simplified since now we do not need *special*
6163 include file to define SFR registers. But a separate header
6164 will be needed. This will be developed later.
6165 * _pic16_parseOptions: added, parses port specific options:
6166 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6167 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6168 --preplace-udata-with=
6170 * _pic16_setDefaultOptions: modified to initialize section names,
6171 but hack is temporarly out of order since it needs improvement.
6172 * _pic16_genAssemblerPreamble: configuration words are emitted by
6173 their address instead of their name. This part is incomplete and
6174 supports only the 18Fxx2 devices. Other devices will emit an error
6175 during assembly since they do not contain the same set of config
6177 * _pic16_genIVT: is modified,
6179 * pcode.c: added definitions for some hardware registers that are needed
6181 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6182 All PCI entries are updated. Now LFSR is supported.
6183 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6184 * added pic16_newpCodeOpLit2 to support instructions with
6185 two literal arguments
6186 * pic16_pCode2str: corrected code that emits assembler instructions
6187 with two literal operands and those that have an access bit modifier
6188 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6189 this fixes a bug which caused some labels to be lost, when an
6190 assembler directive was added, i.e. banksel,
6191 * pic16_FixRegisterBanking: improved logic that causes the insertion
6193 * InlineFunction: functions that are called once, are not any more
6194 inlined. This can be a port option in the future,
6196 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6198 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6199 hold the corresponding uninitialized symbols,
6200 * pic16_allocProcessorRegister: registers have explicit marked the
6202 * pic16_allocInternalRegister: registers are explicit marked as
6204 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6205 processing list, so bit registers were lost,
6208 * ralloc.h: added field 'accessBank' and original symbol operand
6209 in register definition,
6210 * removed the field isMapped from register definition,
6212 ** Several functions have been removed from various sources:
6213 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6214 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6215 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6216 pic16_assignRelocatableRegisters
6218 ** others have been introduced:
6219 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6220 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6222 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6224 * support/scripts/inc2h.pl: changed definition of BIT_AT
6225 to emit 'sbit at' instead of 'bit at'. This was a request.
6227 PIC16 port related preliminary changes:
6228 * gen.c: prefixed function popRegFromString with
6229 pic16_ and all references to it corrected
6230 * pcode.c: all pic16_pc_* hardware registers prefixed
6231 with underscore (_),
6232 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6233 * ralloc.c: newReg(): when register is REG_SFR then
6234 set address to rIdx,
6235 pic16_allocProcessorRegister(): marks register wasUsed=0
6236 pic16_writeUsedRegs(): added a call to assign processor
6237 registers via pic16_assignFixedRegisters
6239 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6241 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6242 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6243 variables in unused register banks. Also the SSEG is placed
6244 wherever there is enough space for it, and IDATA can be anywhere
6245 in internal RAM. For now compile using -Wl-Y[stack_size].
6246 The mem file is different for this option as well, since it
6247 makes no sense of talking about DSEG lenght.
6249 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6251 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6252 in certain cases, e.g. when ROM assignment, patch provided
6253 from Albert den Haan.

6496 * src/SDCCast.c (decorateType): disabled a transformation I added in
6497 revision 1.188 (access to fields of a structure at an absolute address);
6498 it breaks with bitfields, extern declarations, and gcse analysis.
6499 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
6500 could be assigned through a pointer, so don't complain.

6608 xdata initialization slightly shorter
6610 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7256 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
7257 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7258 fetching of the pointer
7259 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7260 copied from genNearPointerSet()
7261 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7262 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

7276 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7278 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7279 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7280 type for bits was changed. It resulted in bit variables becoming
7281 global, which is not permitted in PIC 14 assembly output.
7283 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7285 * doc/sdccman.lyx: various additions and updates. Rearranged sections

7298 A few small changes that speed up the peephole optimizer.
7302 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7304 Try to make the peephole optimizer smarter by maintaining
7305 an association between the assembly source code and the
7306 iCodes that originated them. Put this information to use
7307 with a new peephole rule condition "notVolatile" so that
7308 the rules can be aggressive yet still safe.
7313 * src/mcs51/peeph.def
7315 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7319 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7320 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7321 if the left or right operand symbols have the accuse flag set.
7323 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7325 Changed the type of the result of the ! (NOT) operator to char;
7326 previously it returned the same type as the source. This allows
7327 us to eliminate all the genFloatNot functions (all of its target
7328 implementations were very buggy) since !float can use the same
7331 * src/SDCCicode.c (ast2iCode): ! returns char

7333 * src/ds390/gen.c (genNot, genNotFloat),
7334 * src/z80/gen.c (genNot, genNotFloat),
7335 * src/pic/gen.c (genNot, genNotFloat),

7340 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7341 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7342 during interrupts. Ensure WSAVE is located at a shared bank address.
7343 2. Fixed page selection in some places
7344 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7345 the registers name strings.
7346 4. Fixed "signed / unsigned compare" compiler warnings.
7347 5. The PIC port manages its own allocation of the general purpose
7348 registers, but makes no attempt to reuse them. As a result when
7349 compiling it soon runs out of general purpose registers. Some
7350 additional code was added to the files pcode.c and device.c to walk
7351 through the function call tree and rename the registers so that they
7361 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7362 genPlus() & genMinus() when the result is the same as left or right

7368 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7370 Made bitfield a distinct type from bit so that bitfields
7371 convert as per ANSI C and bits retain their traditional
7372 boolean style behaviour. Implemented bitfield support in
7380 * src/ds390/gen.c: bit v bitfield split
7381 * src/z80/gen.c: New support for bitfields
7382 * support/regression/tests/bitfields.c: reenabled z80,
7385 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7387 Rules 246.x, 247.x relate to bitfields, the others speed up
7388 access to xdata mapped I/O devices.
7390 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7392 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7394 Cleaned up genPackBits and genUnpackBits and added two helper
7395 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7396 for literal assignments in genPackBits (thanks to Frieder for
7402 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7404 Fixed bug #748310 (pointer to function type mishandled when the
7405 function name is omitted). Also fixed a SIGSEGV when a function
7406 attribute (reentrant, etc) is used on a non-function or on a
7407 function but misplaced before the parameter list.
7409 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7411 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7412 * support/Util/SDCCerr.h,
7413 * support/Util/SDCCerr.c: Added func attr misuse error msg

7434 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7436 Made the constant following the "interrupt" keyword optional. If
7437 omitted, the function will not automatically be given an entry
7438 in the interrupt vector table (similar to #pragma NOIV, but
7439 less syntacticly kludgy). The interrupt number is also now
7440 range checked. Also fixed a bug in the high order bit example
7447 * support/Util/SDCCerr.c
7448 * support/Util/SDCCerr.h
7451 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
7453 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
7454 * src/SDCCicode.c (operandOperation): rewritten some ops
7455 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7456 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7458 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7459 be re-activated by defining REDUCE_LITERALS)
7460 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7461 unsigned, but are signed by default
7462 * src/SDCCval.c (constVal): rearranged
7463 * src/SDCCval.c (valMod): preliminary fix
7464 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7506 constants are unsigned; added recognition of "u" flag for unsigned
7507 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
7508 * src/SDCCval.c (valDiv, valMod): fixed signdness
7509 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
7510 signedness of modulo, left and right shift

7962 * src/SDCCmain.c: fixed compiling + linking with object files
7964 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

7969 * src/SDCCmain.c: linkOptions is changed to set *,
7970 added if/endif conditional macros to remove options help
7971 messages from optionsTable when a port is not configured, added
7972 support for the PIc16 port in the ports table, when executing
7973 the compiler with no port specified on command line, a default
7974 port is selected with the new macro DEFAULT_PORT which is
7975 defined in port.h, in setDefaultOptions() linkOptions is removed
7976 from initialization assignment, since now it is a set,
7977 parseCmdLine uses setParseWithComma for linkOptions, in
7978 linkEdit() linkOptions are accessed with new function indexSet()
7979 which returns the i'th item of a set variable. See SDCCset.c, in
7980 linkEdit() when calling buildCmdLine(), added linkOptions as
7981 last argument. Now users can pass arguments to gplink via the
7982 -Wl option, main() uses pic16glue() to glue up pic16 programs

7994 * src/pic16/glue.c: commented out some error producing lines
7995 * src/pic16/main.c: __config directives are commented out to stop
7996 gpasm complaining and test the linkage with gplink, _linkCmd and
7997 _asmCmd changed to be more gplink and gpasm friendly
7998 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7999 produced an error when parsed, peep rule 12 is added to utilize
8000 movff, but it is commented out since the pCode does not support
8001 yet a command with 2 address arguments
8003 2003-05-18 <johan AT balder>
8005 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
8006 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8030 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
8032 2003-05-11 Borut Razem <borut.razem AT siol.net>
8034 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
8035 the path of bin directory, so that PATH is the only env. variable, which has to be set
8036 in case of standard installation.
8037 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

9094 added aopGetUsesAcc() function to allow binary operators to
9095 fetch their operands in the correct order; made genMinus() emit
9096 compact code for X = LITERAL - Y
9098 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9099 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9100 sprintf() in line 1267.
9102 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9103 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9106 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9107 Changes to aslink (All the changes are marked with 'JCF'):
9109 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9112 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9113 area BSEG. Also moves, if possible, the DATA area down into the internal
9114 ram so more space is available.
9116 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9119 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9120 not bytes. Function summary() which creates a memory usage summary
9121 file with extension .mem. Reports of overlaping stack and small stack
9122 size. If the space for the stack is less than 16 bytes aslink trows a
9125 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9126 the 8051. Option 'y' for memory summary output file.
9128 Changes to sdcc (All the changes are marked with 'JCF'):
9130 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9132 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9133 overlaying area for it (uses RegBankUsed[4]).
9135 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9136 bank zero as used by default. By default aslink locates the stack
9137 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9138 the creation of the .mem file. Delegates the allocation of data area
9139 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9140 the begining of the stack area to aslink.
9142 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9143 glue() in SDCCglue.c creates an area for it.
9145 2002-09-03 Borut Razem <borut.razem AT siol.net>
9146 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9147 sdcc/src/pic/glue.c:
9148 introduced atexit() handler for teporay files removal in case of
9149 errors, assertions, ...
9151 2002-08-29 Borut Razem <borut.razem AT siol.net>
9152 * sdcc/support/cpp2/auto-host_vc_in.h:
9153 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9154 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9155 Maybe there is a similar problem with BORLANDC? It should be checked!
9157 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9158 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9159 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9160 was not executed, and the compiler (cl) launched a warning:
9161 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9163 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9164 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9166 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9167 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9169 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9170 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9171 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9172 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9173 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9174 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9175 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9176 - added Release configuration in VS projects
9177 - review of compiler an linker options
9178 - VC .exe files are generated in bin_vc directory, not to interfere
9179 with binaries generated from other projects (cygwin, mingw, bcc ...)
9181 * sdcc/src/yacc.dsp: added
9183 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9184 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9185 and insert the version number definitions from .version
9187 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9189 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9190 added - genarate auto-host.h using auto-host_vc_in.h as template
9193 removed from CVS, generated automatically
9195 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9196 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9198 2002-08-11 Borut Razem <borut.razem AT siol.net>
9199 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9201 2002-08-10 Borut Razem <borut.razem AT siol.net>
9202 * src/SDCCmain.c (main):
9203 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9204 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9205 The consequence was that some temporary files were not removed.
9208 unification of code in functions tempfilename() and tempfile():
9209 function tempnam() is defined in Visual Studio 6.0 and .NET
9211 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9213 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9214 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9215 - removed compiler command line option /WX: Treats all warnings as errors
9216 - update a list of source files, included into the project
9218 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9219 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9220 changed project type to Generic Project so that can be correcly converted to VS.NET project
9222 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9224 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9226 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9228 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9229 added return 0 statements after assert() to make compiler happy
9231 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9232 added newline in the def file to keep MSC compiler satisfied
9234 * sdcc/src/z80/gen.c:
9235 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9236 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9237 - solved MSC error in function aopDump()
9239 * sdcc_vc.h: define PREFIX as "\\sdcc"
9241 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9242 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

9245 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9246 - Rewrote the register banking algorithm.
9247 - Added pCode live-range analysis to registers (for now, only non-used and
9248 singly-used registers optimized away)
9250 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis

9281 2002-03-28 Johan Knol <johan AT balder>
9283 * src/SDCCval.c: fixed bug #532436
9285 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9287 Added "char *Processor" field to the port structure.
9290 Added -p option. Allows port dependent processor to be specified.
9293 Initialized the new field char *Processor field to NULL in all ports
9296 Compiler generated registers for interrupt context saving
9297 were not getting allocated.
9299 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9302 Fixed left shift. Will promote the left side of a left shift
9303 if a) left shifting more than size of operand or b) when assigned
9304 to something size > size of left side
9306 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9308 tons of changes. Register allocation has been
9309 rewritten. Added customization for the various PICs. Flow

9414 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
9416 * sdcc/src/SDCCloop.c:
9417 Previous fix was not good. basic blocks that have "break" or "return" are
9418 not really partof a loop , but live ranges used in these blocks should
9419 be live thru the entire loop, so set partOfLoop but don't add them to
9422 2002-02-21 <johan AT FRIJA>
9424 * src/SDCCcse.c: fixed bug #514308
9426 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
9429 Fixed BUG #519583. If a conditional block ended in a return/break
9430 statement inside a loop, it was not being considered part of the loop.
9432 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
9434 2002-02-10 Karl Bongers <karl AT turbobit.com>
9437 Fixed up SDCDB debugger somewhat. Updated debugger/README
9438 with lots of comments and notes.
9440 * device/examples/test2.c:
9441 Fix bug, "red" variable not being initialized(compiler complained).
