1846 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
1847 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
1848 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1849 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1850 always available in leading double underscore form. The C99 support is
1851 mostly missing, but it's a start.
1852 * support/regression/tests/bug-227710.c: fixed nonconforming use of
1853 reserved identifier "__data".
1855 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

1931 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1933 * device/lib/printf_large.c: removed inline assembly for portability and
1934 readability. Use printf_fast if speed or size are more important.
1935 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1936 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1938 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1940 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1941 prevent compiler warning
1943 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1945 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1946 moved to level 0 and declared as static. Also they are explicit
1947 placed in access bank. This was necessery because some times they
1948 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1949 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1950 optimizations. Currently only compare to unsigned char is implemented,
1951 * src/pic16/gen.c: added fReturnIdx array,
1952 * (struct resolvedIfx) is moved to gen.h and made public,
1953 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1954 * (aopForSym): added an optimization to directly store in stack of
1955 the operand of a SEND iCode,
1956 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1957 but as registers instead (AOP_REG) using the fReturnIdx array,
1958 * (pic16_freeAsmop): remove the freed register from the
1959 _G.sregsAlloc field,
1960 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1961 a compare of 'WREG',
1962 * (pic16_popGetTempRegCond): changed function prototype, now
1963 function takes also a bitVector argument v which holds the current
1964 set of registers that are allocated for stack access by aopForSym,
1965 registers allocated in aopForSym for accessing stack symbols are not
1966 any more part of the functions usedRegs field,
1967 * (genCall): some times aopOp is called for a stack variable to be
1968 send, aopForSym might perform the push, if this is true make sure
1969 that genCall doesn't push the variable twice by testing _G.resDirect,
1970 * (genFunction): changed testing for unspecified interrupt number
1971 from 256 to INTNO_UNSPEC,
1972 * modified selection scheme of frame pointer generation. Previously
1973 if function did use local registers a frame pointer was generated,
1974 now a frame pointer is generated only if function has arguments
1975 (that need PLUSW2 register access), or has stack arguments, or the
1976 compiler is not instructed to omit the frame pointer,
1977 * (genEndFunction): before restoring local registers that were saved
1978 in the function preamble, also restore the registers that *might*
1979 have been allocated for stack access,
1980 * (genRet): removed some old comments,
1981 * (genCmp, the active (RN's) version): added a call to the
1982 pic16_genCmp_special function to perform the compare with a more
1983 robust and optimized way,
1984 * (genInline): a feature has been added in inline code generation,
1985 which allows a wildcard variable substitution when writing inline
1986 assembly. Code is incomplete and experimental therefore undocumented,
1987 * (genCast): changed order of aopOp for result and right to allow
1988 aopForSym to directly load the result if possible,
1989 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1990 perform an optimized compare on some selected special occasions,
1991 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1992 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1993 generate an IVT any more,
1994 * src/pic16/main.c (pic16_optionsTable): added command line option
1996 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1997 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1999 * src/pic16/NOTES: Raphael Neider added in list of active developers
2000 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2001 jumptable_end to prevent bug #,
2002 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2003 inCond and outCond fields,
2004 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2005 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2006 turn off register spilling,
2007 * (packRegsForOneUse): synced with other ports' versions although it
2008 is not used currently,
2009 * (pic16_packRegisters): added an optimization while reading
2010 structure bitfields, some registers may be saved (malloc code is
2011 decreased by 80 bytes)
2013 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2015 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2016 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2017 this can be optimized more?
2019 2005-03-10 Raphael Neider <rneider AT web.de>
2021 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2022 genNearPointerGet): (hopefully) fixed access to bitfields via
2023 pointers (p->bitN = x; and x = p->bitN; failed)

2657 Adding support for replacing ljmps with sjmps in jumptables
2658 generated for switch statements. For now you need to set the
2659 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2660 Now 4 algorithms for mcs51 jumptable generation are used:
2661 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2662 addresses loaded pc-relative for up to 112 cases and stack-pushing
2663 target addresses loaded with offset from dptr for up to 256 cases.

2690 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
2691 to call when a stack overflow occurs,
2692 * (malloc.h): added CVS Id tag,
2693 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2695 * added libc directory. The current version of LibC contains string
2696 functions, ctype functions and macros and some functions of the
2697 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2698 be extensively tested in the future. Standard disclaimer here.
2699 Library is not automatically build yet. But one can build it by
2700 invoking 'make' inside the libc directory.
2701 * added ADC library under libio. Preliminary version yet.

2710 * (genUminusFloat): fixed for pic16, ported code from mcs51,
2711 * (pic16_storeForReturn): optimized return of 0,
2712 * (genCmp): experimental code for new genCmp which uses PIC18's
2713 special compare&skip instructions. Initial tests fail some times
2714 with variables grater than 1 byte in size, so new code is disabled,
2715 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2717 * (genCast): began a fix to optimize the casting of a bit to another
2718 bit, now assigning a bitfield to another bitfield will fail, sorry,
2719 * src/pic16/main.c: disabled the use of lr-support feature,
2720 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

2723 bits with offset (case PO_GPR_BIT),
2724 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
2726 * (isBankInstruction): modified to return 0 for no banking instruction,
2727 and 1 for banking instruction,
2728 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2729 caused stop processing pCodes after a inline assembly block,
2730 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
2731 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
2732 registers when it shouldn't,
2733 * src/pic16/ralloc.c (allocReg): add preliminary support for
2734 supporting a limited set of temporary registers,
2736 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2738 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,

2741 (loadRegFromAop): recognize CLRH optimization,
2742 (genFunction): optimize RECEIVE iCodes in reentrant functions
2744 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2746 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

5693 * src/pic/ralloc.h: applied patch from Slade Rich;
5694 added support for multiple code pages and multiple RAM banks on the
5695 PIC 14 port. The ASM files now no longer simply assume all the
5696 code / RAM are in the same page / bank. This means the linker can
5697 safely allocate code/RAM of separate ASM files to different pages/banks.
5698 * doc/sdccman.lyx: added Slade's tips
5699 * src/mcs51/peeph.def: fixed bug #880768

5708 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
5711 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
5712 strtof is not part of C89 and isn't included with Mac OS X.
5714 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5716 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,
5717 shiftL2Left2Result): fixed bug #879326
5718 (genAnd, genOr, genXor): fixed bug when result was of type AOP_CRY

5741 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5743 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5744 loaded with the linker search paths (-L arguments) and the libraries
5745 to be linked with the current source (-l arguments). Changes
5746 currently will affect only the pic16 port.
5747 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5748 include path the port specific paths and port specific libraries,
5749 * gplink command now contains the $3 argument,
5750 * src/pic16/device.h,
5751 * src/pic16/device.c,: structure PIC_device is made public and
5752 renamed to PIC16_device, the same for variable Pics which is renamed
5753 to Pics16. Updated all references to them.
5754 * src/pic16/glue.c (pic16glue): corrected bug with code
5755 initialization which bypassed the variable initializations block.
5757 * device/lib/pic16/Makefile.rules: removed --penable-stack from
5758 COMPILE_FLAGS and added the --nostdinc option
5760 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5765 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
5767 Documenting changes from previous commits.
5768 * configure.in (version 1.56),
5769 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5770 when generating output files to configure the pic16 library,
5771 but now I've commented it out, since gputils aren't installed in the
5772 SF compile farm, so library won't compile
5774 * device/lib/Makefile.in (version 1.56): initially I've added in
5775 target 'all' the prerequestive 'model-pic16' so it compiled the
5776 pic16 library, but now I've commented it out for the same reasons
5778 * added targets 'model-pic16' and 'objects-pic16' to compile the
5780 * added target 'port-specific-objects-pic16' to handle the
5781 generated libraries and copy them into the build/ directory
5782 * added target 'clean-intermediate-pic16' to clean intermediate
5783 files into pic16 directory
5784 * in target 'installdirs' added line to create directory pic16 in
5785 the installation path
5787 * device/include/Makefile.in (version 1.11): in target 'install'
5788 added lines to copy all header files to installation path,
5789 * in target 'installdirs' added line create directory for pic16
5790 headers in the installation path

5805 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5806 option so that it actually works. Made it specific to the z80, since
5807 the gbz80 doesn't have these kinds of I/O ports.
5809 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5811 * device/include/z180.h,

5824 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5826 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
5827 changed interrupt vector table generation to only emit declared vectors.

5833 Mainly changes to support compilation of the device libraries
5834 * src/pic16/device.c: stack is allocated via symbol and not
5835 via literal number. The symbol is placed in the corresponding
5836 position of the data ram
5837 * (pic16_dump_section): relocatable and absolute uninitialized
5838 data are now emitted in sorted order to reduce section naming,
5839 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5840 weren't marked as being in the access bank,
5842 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5844 Added portion of GNU PIC Library under the directory
5845 device/include/pic16 and device/lib/pic16. These files
5846 contain the declarations of SFRs for the PIC18Fxx2 devices.
5847 The directory is initialized via configure from toplevel.
5849 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
5851 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
5852 the spilllocations to be compared correctly
5854 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>

5861 doc/sdccman.lyx: upper case pragmas are deprecated
5863 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
5865 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
5866 in simpler and even better code
5868 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
5870 * src/SDCCicode.c (operandOperation): fixed bug #874819

5876 * doc/sdccman.lyx: Moved and added some sections, small changes
5877 all over. Telling LaTeX to be less strict with word spacing
5878 to better keep the right margin. Changed some notes about
5879 maintainance of the ports in section 3.2.1 - is it OK like this?
5881 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5919 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5921 * src/pic16/peeph.def: all peepholes with movff are commented out,
5922 because there is a problem in the pcode peep optimizer,
5923 * src/pic16/ralloc.c: the register allocator can now reuse local

6038 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6040 A python script to validate compiler diagnostic messages. It can be
6041 used to verify that sdcc complains about bad c source code and

6043 * support/valdiag/Makefile,
6044 * support/valdiag/valdiag.py,
6045 * support/valdiag/tests/*

6075 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6077 PIC16 port related changes:
6078 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6079 added variable stackPos,
6081 * gen.c: genCall, assignResultValue: added support for
6082 pushing/retrieving function parameters to/from stack,
6083 genFunction,genEndFunction: setup stack frame for the
6085 genAddrOf: will be changed according to bug 863624
6087 * added files genutils.c and genutils.h which contain gen*
6088 debugged and optimised functions extracted from gen.c
6090 * glue.c: added variable 'externs' which holds extern symbols,
6091 pic16emitRegularMap: is modified to properly handle relocatable
6092 symbols under the new scheme,
6093 pic16createInterruptVect: is modified
6094 pic16printPublics: is modified to emit 'global' assembler directives,
6095 added pic16_printExterns to print extern symbols,
6096 pic16glue: initializes stack/frame pointer in the beginning of
6097 the assembly output. Temporary hack, will be corrected later,
6098 because gplink yet does not support stack and SDCC does not
6099 yet support a type of crt0.o object to create the final binary.
6101 * Removed many lines that contain 8051 legacy code.
6102 * The code is finally placed under a 'code' directive.
6103 * Added port specific options.
6105 * _process_pragma: simplified since now we do not need *special*
6106 include file to define SFR registers. But a separate header
6107 will be needed. This will be developed later.
6108 * _pic16_parseOptions: added, parses port specific options:
6109 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6110 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6111 --preplace-udata-with=
6113 * _pic16_setDefaultOptions: modified to initialize section names,
6114 but hack is temporarly out of order since it needs improvement.
6115 * _pic16_genAssemblerPreamble: configuration words are emitted by
6116 their address instead of their name. This part is incomplete and
6117 supports only the 18Fxx2 devices. Other devices will emit an error
6118 during assembly since they do not contain the same set of config
6120 * _pic16_genIVT: is modified,
6122 * pcode.c: added definitions for some hardware registers that are needed
6124 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6125 All PCI entries are updated. Now LFSR is supported.
6126 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6127 * added pic16_newpCodeOpLit2 to support instructions with
6128 two literal arguments
6129 * pic16_pCode2str: corrected code that emits assembler instructions
6130 with two literal operands and those that have an access bit modifier
6131 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6132 this fixes a bug which caused some labels to be lost, when an
6133 assembler directive was added, i.e. banksel,
6134 * pic16_FixRegisterBanking: improved logic that causes the insertion
6136 * InlineFunction: functions that are called once, are not any more
6137 inlined. This can be a port option in the future,
6139 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6141 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6142 hold the corresponding uninitialized symbols,
6143 * pic16_allocProcessorRegister: registers have explicit marked the
6145 * pic16_allocInternalRegister: registers are explicit marked as
6147 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6148 processing list, so bit registers were lost,
6151 * ralloc.h: added field 'accessBank' and original symbol operand
6152 in register definition,
6153 * removed the field isMapped from register definition,
6155 ** Several functions have been removed from various sources:
6156 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6157 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6158 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6159 pic16_assignRelocatableRegisters
6161 ** others have been introduced:
6162 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6163 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6165 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6167 * support/scripts/inc2h.pl: changed definition of BIT_AT
6168 to emit 'sbit at' instead of 'bit at'. This was a request.
6170 PIC16 port related preliminary changes:
6171 * gen.c: prefixed function popRegFromString with
6172 pic16_ and all references to it corrected
6173 * pcode.c: all pic16_pc_* hardware registers prefixed
6174 with underscore (_),
6175 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6176 * ralloc.c: newReg(): when register is REG_SFR then
6177 set address to rIdx,
6178 pic16_allocProcessorRegister(): marks register wasUsed=0
6179 pic16_writeUsedRegs(): added a call to assign processor
6180 registers via pic16_assignFixedRegisters
6182 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6184 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6185 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6186 variables in unused register banks. Also the SSEG is placed
6187 wherever there is enough space for it, and IDATA can be anywhere
6188 in internal RAM. For now compile using -Wl-Y[stack_size].
6189 The mem file is different for this option as well, since it
6190 makes no sense of talking about DSEG lenght.
6192 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6194 * src/SDCClrange.c: fixed bug 869095 that caused segfault

7185 and JUMPTABLE iCodes properly now (worked by accident before)
7186 * src/mcs51/gen.c (leftRightUseAcc),
7187 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
7188 iCode properly now. Use getSize instead of nRegs since a & b
7189 aren't part of the nRegs tally.
7191 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
7193 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

7199 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
7200 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7201 fetching of the pointer
7202 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7203 copied from genNearPointerSet()
7204 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7205 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
7206 If they pop r0/r1 they must be called in the opposite order than aopOp().
7207 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
7208 (resp. --stack-auto), prepared for --xstack

7219 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7221 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7222 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7223 type for bits was changed. It resulted in bit variables becoming
7224 global, which is not permitted in PIC 14 assembly output.
7226 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7228 * doc/sdccman.lyx: various additions and updates. Rearranged sections

7241 A few small changes that speed up the peephole optimizer.
7245 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7247 Try to make the peephole optimizer smarter by maintaining
7248 an association between the assembly source code and the
7249 iCodes that originated them. Put this information to use
7250 with a new peephole rule condition "notVolatile" so that
7251 the rules can be aggressive yet still safe.
7256 * src/mcs51/peeph.def
7258 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7262 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7263 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7264 if the left or right operand symbols have the accuse flag set.
7266 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7268 Changed the type of the result of the ! (NOT) operator to char;
7269 previously it returned the same type as the source. This allows
7270 us to eliminate all the genFloatNot functions (all of its target
7271 implementations were very buggy) since !float can use the same
7274 * src/SDCCicode.c (ast2iCode): ! returns char

7283 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7284 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7285 during interrupts. Ensure WSAVE is located at a shared bank address.
7286 2. Fixed page selection in some places
7287 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7288 the registers name strings.
7289 4. Fixed "signed / unsigned compare" compiler warnings.
7290 5. The PIC port manages its own allocation of the general purpose
7291 registers, but makes no attempt to reuse them. As a result when
7292 compiling it soon runs out of general purpose registers. Some
7293 additional code was added to the files pcode.c and device.c to walk
7294 through the function call tree and rename the registers so that they
7304 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

7311 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7313 Made bitfield a distinct type from bit so that bitfields
7314 convert as per ANSI C and bits retain their traditional
7315 boolean style behaviour. Implemented bitfield support in
7323 * src/ds390/gen.c: bit v bitfield split
7324 * src/z80/gen.c: New support for bitfields
7325 * support/regression/tests/bitfields.c: reenabled z80,
7328 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7330 Rules 246.x, 247.x relate to bitfields, the others speed up
7331 access to xdata mapped I/O devices.
7333 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7335 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7337 Cleaned up genPackBits and genUnpackBits and added two helper
7338 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7339 for literal assignments in genPackBits (thanks to Frieder for
7345 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7347 Fixed bug #748310 (pointer to function type mishandled when the
7348 function name is omitted). Also fixed a SIGSEGV when a function
7349 attribute (reentrant, etc) is used on a non-function or on a
7350 function but misplaced before the parameter list.
7352 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7354 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7355 * support/Util/SDCCerr.h,

7377 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7379 Made the constant following the "interrupt" keyword optional. If
7380 omitted, the function will not automatically be given an entry
7381 in the interrupt vector table (similar to #pragma NOIV, but
7382 less syntacticly kludgy). The interrupt number is also now
7383 range checked. Also fixed a bug in the high order bit example

7404 unsigned, but are signed by default
7405 * src/SDCCval.c (constVal): rearranged
7406 * src/SDCCval.c (valMod): preliminary fix
7407 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7859 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
7860 the regression tests I'm not brave enough to enable 245.b, 245.c
7861 * doc/sdccman.lyx: added latex preamble for hyperref package.
7862 Using pdflatex this will give you a hyperlinked pdf file with
7863 bookmarks. (prepend '%' before /usepackage if this breaks something)

7879 Applied patch from bug 737905 (renamed yylineo to mylineno):
7886 * src/pic16/pcode.c: Cleaned warnings
7887 * src/pic16/pcodeflow.c: Cleaned warnings

7899 * src/pic16/pcode.c (pic16_get_op): fixed warning on alpha
7901 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
7903 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
7904 it can be defined with CFLAGS when running configure
7905 * src/SDCCmain.c: fixed compiling + linking with object files
7907 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
7909 * configure.in: configure for pic16 port,
7910 added --disable-pic16-port
7911 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7912 * src/SDCCmain.c: linkOptions is changed to set *,
7913 added if/endif conditional macros to remove options help
7914 messages from optionsTable when a port is not configured, added
7915 support for the PIc16 port in the ports table, when executing
7916 the compiler with no port specified on command line, a default
7917 port is selected with the new macro DEFAULT_PORT which is
7918 defined in port.h, in setDefaultOptions() linkOptions is removed
7919 from initialization assignment, since now it is a set,
7920 parseCmdLine uses setParseWithComma for linkOptions, in
7921 linkEdit() linkOptions are accessed with new function indexSet()
7922 which returns the i'th item of a set variable. See SDCCset.c, in
7923 linkEdit() when calling buildCmdLine(), added linkOptions as
7924 last argument. Now users can pass arguments to gplink via the
7925 -Wl option, main() uses pic16glue() to glue up pic16 programs
7926 * src/SDCCpeeph.c: various changes to support pic16
7927 * src/SDCCset.c: added function void *indexSet(set *, int) to
7928 return the i'th item of the set

7933 added macro DEFAULT_PORT
7934 * src/pic/main.c: corrected arguments of gplnk in _linkCmd
7935 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
7937 * src/pic16/glue.c: commented out some error producing lines
7938 * src/pic16/main.c: __config directives are commented out to stop
7939 gpasm complaining and test the linkage with gplink, _linkCmd and
7940 _asmCmd changed to be more gplink and gpasm friendly
7941 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7942 produced an error when parsed, peep rule 12 is added to utilize
7943 movff, but it is commented out since the pCode does not support
7944 yet a command with 2 address arguments
7946 2003-05-18 <johan AT balder>
7948 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
7949 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7975 2003-05-11 Borut Razem <borut.razem AT siol.net>
7977 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7978 the path of bin directory, so that PATH is the only env. variable, which has to be set
7979 in case of standard installation.
7980 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

9009 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9011 * in \sdcc\as\mcs51\ changed these files in order to create an
9012 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9013 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9014 following files to include the previous two files: aslink.dsp,
9015 Makefile.aslink, Makefile.bcc, and Makefile.in.
9017 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9018 .adb instead of .cdb
9020 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9022 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9023 value from option --iram-size.
9025 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9027 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9030 2002-09-18 <wiml AT hhhh.org>
9032 * SDCClrange.h: exposed setFromRange() and setToRange()
9033 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9034 packRegsForAccUse() (bug 542397)
9035 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9036 multiple times and emitting the fetch operations more than once
9037 added aopGetUsesAcc() function to allow binary operators to
9038 fetch their operands in the correct order; made genMinus() emit
9039 compact code for X = LITERAL - Y
9041 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9042 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9043 sprintf() in line 1267.
9045 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9046 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9049 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9050 Changes to aslink (All the changes are marked with 'JCF'):
9052 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9055 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9056 area BSEG. Also moves, if possible, the DATA area down into the internal
9057 ram so more space is available.
9059 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9062 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9063 not bytes. Function summary() which creates a memory usage summary
9064 file with extension .mem. Reports of overlaping stack and small stack
9065 size. If the space for the stack is less than 16 bytes aslink trows a
9068 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9069 the 8051. Option 'y' for memory summary output file.
9071 Changes to sdcc (All the changes are marked with 'JCF'):
9073 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9075 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9076 overlaying area for it (uses RegBankUsed[4]).
9078 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9079 bank zero as used by default. By default aslink locates the stack
9080 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9081 the creation of the .mem file. Delegates the allocation of data area
9082 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9083 the begining of the stack area to aslink.
9085 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9086 glue() in SDCCglue.c creates an area for it.
9088 2002-09-03 Borut Razem <borut.razem AT siol.net>
9089 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9090 sdcc/src/pic/glue.c:
9091 introduced atexit() handler for teporay files removal in case of
9092 errors, assertions, ...
9094 2002-08-29 Borut Razem <borut.razem AT siol.net>
9095 * sdcc/support/cpp2/auto-host_vc_in.h:
9096 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9097 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9098 Maybe there is a similar problem with BORLANDC? It should be checked!
9100 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9101 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9102 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9103 was not executed, and the compiler (cl) launched a warning:
9104 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9106 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9107 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9109 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9110 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9112 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9113 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9114 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9115 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9116 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9117 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9118 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9119 - added Release configuration in VS projects
9120 - review of compiler an linker options
9121 - VC .exe files are generated in bin_vc directory, not to interfere
9122 with binaries generated from other projects (cygwin, mingw, bcc ...)
9124 * sdcc/src/yacc.dsp: added
9126 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9127 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9128 and insert the version number definitions from .version
9130 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9132 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9133 added - genarate auto-host.h using auto-host_vc_in.h as template
9136 removed from CVS, generated automatically
9138 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>

9141 2002-08-11 Borut Razem <borut.razem AT siol.net>
9142 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9144 2002-08-10 Borut Razem <borut.razem AT siol.net>
9145 * src/SDCCmain.c (main):
9146 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9147 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9148 The consequence was that some temporary files were not removed.
9151 unification of code in functions tempfilename() and tempfile():
9152 function tempnam() is defined in Visual Studio 6.0 and .NET
9154 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9156 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9157 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9158 - removed compiler command line option /WX: Treats all warnings as errors
9159 - update a list of source files, included into the project
9161 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9162 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9163 changed project type to Generic Project so that can be correcly converted to VS.NET project
9165 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9167 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9169 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9171 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9172 added return 0 statements after assert() to make compiler happy
9174 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9175 added newline in the def file to keep MSC compiler satisfied
9177 * sdcc/src/z80/gen.c:
9178 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9179 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9180 - solved MSC error in function aopDump()
9182 * sdcc_vc.h: define PREFIX as "\\sdcc"
9184 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9185 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

9233 Added -p option. Allows port dependent processor to be specified.
9236 Initialized the new field char *Processor field to NULL in all ports
9239 Compiler generated registers for interrupt context saving
9240 were not getting allocated.
9242 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9245 Fixed left shift. Will promote the left side of a left shift
9246 if a) left shifting more than size of operand or b) when assigned
9247 to something size > size of left side
9249 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9251 tons of changes. Register allocation has been
9252 rewritten. Added customization for the various PICs. Flow

9357 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
9359 * sdcc/src/SDCCloop.c:
9360 Previous fix was not good. basic blocks that have "break" or "return" are
9361 not really partof a loop , but live ranges used in these blocks should
9362 be live thru the entire loop, so set partOfLoop but don't add them to
9365 2002-02-21 <johan AT FRIJA>
9367 * src/SDCCcse.c: fixed bug #514308
9369 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

9388 for use as a multiple module SDCDB test case.
9390 * sim/ucsim/cmd.src/cmdset.cc:
9391 Took out debug printfs in ucsim "next" command.
9394 Karl and Johan start ucsim XA support. Most dissassembly working,
9395 about 75% emulation done(plenty of work remaining).
9397 * sim/ucsim/z80.src:
9398 Add Z80 support to ucsim, add test-ucz80 regression test,
9399 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
