1842 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
1843 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1844 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1845 always available in leading double underscore form. The C99 support is
1846 mostly missing, but it's a start.
1847 * support/regression/tests/bug-227710.c: fixed nonconforming use of

1926 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1928 * device/lib/printf_large.c: removed inline assembly for portability and
1929 readability. Use printf_fast if speed or size are more important.
1930 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1931 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1933 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1935 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1936 prevent compiler warning
1938 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1940 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1941 moved to level 0 and declared as static. Also they are explicit
1942 placed in access bank. This was necessery because some times they
1943 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1944 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1945 optimizations. Currently only compare to unsigned char is implemented,
1946 * src/pic16/gen.c: added fReturnIdx array,
1947 * (struct resolvedIfx) is moved to gen.h and made public,
1948 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1949 * (aopForSym): added an optimization to directly store in stack of
1950 the operand of a SEND iCode,
1951 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1952 but as registers instead (AOP_REG) using the fReturnIdx array,
1953 * (pic16_freeAsmop): remove the freed register from the
1954 _G.sregsAlloc field,
1955 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1956 a compare of 'WREG',
1957 * (pic16_popGetTempRegCond): changed function prototype, now
1958 function takes also a bitVector argument v which holds the current
1959 set of registers that are allocated for stack access by aopForSym,
1960 registers allocated in aopForSym for accessing stack symbols are not
1961 any more part of the functions usedRegs field,
1962 * (genCall): some times aopOp is called for a stack variable to be
1963 send, aopForSym might perform the push, if this is true make sure
1964 that genCall doesn't push the variable twice by testing _G.resDirect,
1965 * (genFunction): changed testing for unspecified interrupt number
1966 from 256 to INTNO_UNSPEC,
1967 * modified selection scheme of frame pointer generation. Previously
1968 if function did use local registers a frame pointer was generated,
1969 now a frame pointer is generated only if function has arguments
1970 (that need PLUSW2 register access), or has stack arguments, or the
1971 compiler is not instructed to omit the frame pointer,
1972 * (genEndFunction): before restoring local registers that were saved
1973 in the function preamble, also restore the registers that *might*
1974 have been allocated for stack access,
1975 * (genRet): removed some old comments,
1976 * (genCmp, the active (RN's) version): added a call to the
1977 pic16_genCmp_special function to perform the compare with a more
1978 robust and optimized way,
1979 * (genInline): a feature has been added in inline code generation,
1980 which allows a wildcard variable substitution when writing inline
1981 assembly. Code is incomplete and experimental therefore undocumented,
1982 * (genCast): changed order of aopOp for result and right to allow
1983 aopForSym to directly load the result if possible,
1984 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1985 perform an optimized compare on some selected special occasions,
1986 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1987 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1988 generate an IVT any more,
1989 * src/pic16/main.c (pic16_optionsTable): added command line option
1991 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1992 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1994 * src/pic16/NOTES: Raphael Neider added in list of active developers
1995 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1996 jumptable_end to prevent bug #,
1997 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1998 inCond and outCond fields,
1999 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2000 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2001 turn off register spilling,
2002 * (packRegsForOneUse): synced with other ports' versions although it
2003 is not used currently,
2004 * (pic16_packRegisters): added an optimization while reading
2005 structure bitfields, some registers may be saved (malloc code is
2006 decreased by 80 bytes)
2008 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2010 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2011 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2012 this can be optimized more?
2014 2005-03-10 Raphael Neider <rneider AT web.de>
2016 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2017 genNearPointerGet): (hopefully) fixed access to bitfields via
2018 pointers (p->bitN = x; and x = p->bitN; failed)

2652 Adding support for replacing ljmps with sjmps in jumptables
2653 generated for switch statements. For now you need to set the
2654 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2655 Now 4 algorithms for mcs51 jumptable generation are used:
2656 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2657 addresses loaded pc-relative for up to 112 cases and stack-pushing
2658 target addresses loaded with offset from dptr for up to 256 cases.

2685 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
2686 to call when a stack overflow occurs,
2687 * (malloc.h): added CVS Id tag,
2688 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2690 * added libc directory. The current version of LibC contains string
2691 functions, ctype functions and macros and some functions of the
2692 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2693 be extensively tested in the future. Standard disclaimer here.
2694 Library is not automatically build yet. But one can build it by
2695 invoking 'make' inside the libc directory.
2696 * added ADC library under libio. Preliminary version yet.
2698 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

2705 * (genUminusFloat): fixed for pic16, ported code from mcs51,
2706 * (pic16_storeForReturn): optimized return of 0,
2707 * (genCmp): experimental code for new genCmp which uses PIC18's
2708 special compare&skip instructions. Initial tests fail some times
2709 with variables grater than 1 byte in size, so new code is disabled,
2710 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2712 * (genCast): began a fix to optimize the casting of a bit to another
2713 bit, now assigning a bitfield to another bitfield will fail, sorry,
2714 * src/pic16/main.c: disabled the use of lr-support feature,
2715 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

2718 bits with offset (case PO_GPR_BIT),
2719 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
2721 * (isBankInstruction): modified to return 0 for no banking instruction,
2722 and 1 for banking instruction,
2723 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2724 caused stop processing pCodes after a inline assembly block,
2725 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
2726 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
2727 registers when it shouldn't,
2728 * src/pic16/ralloc.c (allocReg): add preliminary support for
2729 supporting a limited set of temporary registers,
2731 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2733 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
2734 genDataPointerSet): ensure assignments always copy in MSB to LSB
2736 (loadRegFromAop): recognize CLRH optimization,
2737 (genFunction): optimize RECEIVE iCodes in reentrant functions
2739 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2741 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

5691 code / RAM are in the same page / bank. This means the linker can
5692 safely allocate code/RAM of separate ASM files to different pages/banks.
5693 * doc/sdccman.lyx: added Slade's tips
5694 * src/mcs51/peeph.def: fixed bug #880768

5703 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
5706 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
5707 strtof is not part of C89 and isn't included with Mac OS X.
5709 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5711 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,
5712 shiftL2Left2Result): fixed bug #879326
5713 (genAnd, genOr, genXor): fixed bug when result was of type AOP_CRY

5736 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5738 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5739 loaded with the linker search paths (-L arguments) and the libraries
5740 to be linked with the current source (-l arguments). Changes
5741 currently will affect only the pic16 port.
5742 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5743 include path the port specific paths and port specific libraries,
5744 * gplink command now contains the $3 argument,
5745 * src/pic16/device.h,
5746 * src/pic16/device.c,: structure PIC_device is made public and
5747 renamed to PIC16_device, the same for variable Pics which is renamed
5748 to Pics16. Updated all references to them.
5749 * src/pic16/glue.c (pic16glue): corrected bug with code
5750 initialization which bypassed the variable initializations block.

5760 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
5762 Documenting changes from previous commits.
5763 * configure.in (version 1.56),
5764 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5765 when generating output files to configure the pic16 library,
5766 but now I've commented it out, since gputils aren't installed in the
5767 SF compile farm, so library won't compile
5769 * device/lib/Makefile.in (version 1.56): initially I've added in
5770 target 'all' the prerequestive 'model-pic16' so it compiled the
5771 pic16 library, but now I've commented it out for the same reasons
5773 * added targets 'model-pic16' and 'objects-pic16' to compile the
5775 * added target 'port-specific-objects-pic16' to handle the
5776 generated libraries and copy them into the build/ directory
5777 * added target 'clean-intermediate-pic16' to clean intermediate
5778 files into pic16 directory
5779 * in target 'installdirs' added line to create directory pic16 in
5780 the installation path
5782 * device/include/Makefile.in (version 1.11): in target 'install'
5783 added lines to copy all header files to installation path,
5784 * in target 'installdirs' added line create directory for pic16
5785 headers in the installation path

5800 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5801 option so that it actually works. Made it specific to the z80, since
5802 the gbz80 doesn't have these kinds of I/O ports.
5804 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5806 * device/include/z180.h,

5828 Mainly changes to support compilation of the device libraries
5829 * src/pic16/device.c: stack is allocated via symbol and not
5830 via literal number. The symbol is placed in the corresponding
5831 position of the data ram
5832 * (pic16_dump_section): relocatable and absolute uninitialized
5833 data are now emitted in sorted order to reduce section naming,
5834 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5835 weren't marked as being in the access bank,
5837 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5839 Added portion of GNU PIC Library under the directory
5840 device/include/pic16 and device/lib/pic16. These files
5841 contain the declarations of SFRs for the PIC18Fxx2 devices.
5842 The directory is initialized via configure from toplevel.
5844 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
5846 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

5856 doc/sdccman.lyx: upper case pragmas are deprecated
5858 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
5860 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
5861 in simpler and even better code

5871 * doc/sdccman.lyx: Moved and added some sections, small changes
5872 all over. Telling LaTeX to be less strict with word spacing
5873 to better keep the right margin. Changed some notes about
5874 maintainance of the ports in section 3.2.1 - is it OK like this?
5876 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5914 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5916 * src/pic16/peeph.def: all peepholes with movff are commented out,
5917 because there is a problem in the pcode peep optimizer,
5918 * src/pic16/ralloc.c: the register allocator can now reuse local

6033 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6035 A python script to validate compiler diagnostic messages. It can be
6036 used to verify that sdcc complains about bad c source code and
6037 gives a good location of the error.
6038 * support/valdiag/Makefile,
6039 * support/valdiag/valdiag.py,
6040 * support/valdiag/tests/*

6057 Bug reported from Jesus Calvino-Fraga
6059 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6061 * sdcc.spec: updated
6062 * device/include/Makefile.in: don't install CVS directories

6070 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6072 PIC16 port related changes:
6073 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6074 added variable stackPos,
6076 * gen.c: genCall, assignResultValue: added support for
6077 pushing/retrieving function parameters to/from stack,
6078 genFunction,genEndFunction: setup stack frame for the
6080 genAddrOf: will be changed according to bug 863624
6082 * added files genutils.c and genutils.h which contain gen*
6083 debugged and optimised functions extracted from gen.c
6085 * glue.c: added variable 'externs' which holds extern symbols,
6086 pic16emitRegularMap: is modified to properly handle relocatable
6087 symbols under the new scheme,
6088 pic16createInterruptVect: is modified
6089 pic16printPublics: is modified to emit 'global' assembler directives,
6090 added pic16_printExterns to print extern symbols,
6091 pic16glue: initializes stack/frame pointer in the beginning of
6092 the assembly output. Temporary hack, will be corrected later,
6093 because gplink yet does not support stack and SDCC does not
6094 yet support a type of crt0.o object to create the final binary.
6096 * Removed many lines that contain 8051 legacy code.
6097 * The code is finally placed under a 'code' directive.
6098 * Added port specific options.
6100 * _process_pragma: simplified since now we do not need *special*
6101 include file to define SFR registers. But a separate header
6102 will be needed. This will be developed later.
6103 * _pic16_parseOptions: added, parses port specific options:
6104 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6105 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6106 --preplace-udata-with=
6108 * _pic16_setDefaultOptions: modified to initialize section names,
6109 but hack is temporarly out of order since it needs improvement.
6110 * _pic16_genAssemblerPreamble: configuration words are emitted by
6111 their address instead of their name. This part is incomplete and
6112 supports only the 18Fxx2 devices. Other devices will emit an error
6113 during assembly since they do not contain the same set of config
6115 * _pic16_genIVT: is modified,
6117 * pcode.c: added definitions for some hardware registers that are needed
6119 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6120 All PCI entries are updated. Now LFSR is supported.
6121 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6122 * added pic16_newpCodeOpLit2 to support instructions with
6123 two literal arguments
6124 * pic16_pCode2str: corrected code that emits assembler instructions
6125 with two literal operands and those that have an access bit modifier
6126 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6127 this fixes a bug which caused some labels to be lost, when an
6128 assembler directive was added, i.e. banksel,
6129 * pic16_FixRegisterBanking: improved logic that causes the insertion
6131 * InlineFunction: functions that are called once, are not any more
6132 inlined. This can be a port option in the future,
6134 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6136 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6137 hold the corresponding uninitialized symbols,
6138 * pic16_allocProcessorRegister: registers have explicit marked the
6140 * pic16_allocInternalRegister: registers are explicit marked as
6142 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6143 processing list, so bit registers were lost,
6146 * ralloc.h: added field 'accessBank' and original symbol operand
6147 in register definition,
6148 * removed the field isMapped from register definition,
6150 ** Several functions have been removed from various sources:
6151 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6152 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6153 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6154 pic16_assignRelocatableRegisters
6156 ** others have been introduced:
6157 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6158 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6160 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6162 * support/scripts/inc2h.pl: changed definition of BIT_AT
6163 to emit 'sbit at' instead of 'bit at'. This was a request.
6165 PIC16 port related preliminary changes:
6166 * gen.c: prefixed function popRegFromString with
6167 pic16_ and all references to it corrected
6168 * pcode.c: all pic16_pc_* hardware registers prefixed
6169 with underscore (_),
6170 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6171 * ralloc.c: newReg(): when register is REG_SFR then
6172 set address to rIdx,
6173 pic16_allocProcessorRegister(): marks register wasUsed=0
6174 pic16_writeUsedRegs(): added a call to assign processor
6175 registers via pic16_assignFixedRegisters
6177 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6179 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6180 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6181 variables in unused register banks. Also the SSEG is placed
6182 wherever there is enough space for it, and IDATA can be anywhere
6183 in internal RAM. For now compile using -Wl-Y[stack_size].
6184 The mem file is different for this option as well, since it
6185 makes no sense of talking about DSEG lenght.

6436 it breaks with bitfields, extern declarations, and gcse analysis.

7180 and JUMPTABLE iCodes properly now (worked by accident before)
7181 * src/mcs51/gen.c (leftRightUseAcc),
7182 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
7183 iCode properly now. Use getSize instead of nRegs since a & b
7184 aren't part of the nRegs tally.
7186 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
7188 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()
7189 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive

7192 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
7194 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
7195 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7196 fetching of the pointer
7197 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7198 copied from genNearPointerSet()
7199 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7200 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
7201 If they pop r0/r1 they must be called in the opposite order than aopOp().
7202 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
7203 (resp. --stack-auto), prepared for --xstack

7212 these ports have their own __sdcc_external_start()
7214 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7216 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7217 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7218 type for bits was changed. It resulted in bit variables becoming
7219 global, which is not permitted in PIC 14 assembly output.
7221 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7223 * doc/sdccman.lyx: various additions and updates. Rearranged sections

7236 A few small changes that speed up the peephole optimizer.
7240 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7242 Try to make the peephole optimizer smarter by maintaining
7243 an association between the assembly source code and the
7244 iCodes that originated them. Put this information to use
7245 with a new peephole rule condition "notVolatile" so that
7246 the rules can be aggressive yet still safe.
7251 * src/mcs51/peeph.def
7253 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7257 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7258 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7259 if the left or right operand symbols have the accuse flag set.
7261 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7263 Changed the type of the result of the ! (NOT) operator to char;
7264 previously it returned the same type as the source. This allows
7265 us to eliminate all the genFloatNot functions (all of its target
7266 implementations were very buggy) since !float can use the same
7269 * src/SDCCicode.c (ast2iCode): ! returns char
7270 * src/mcs51/gen.c (genNot, genNotFloat),
7271 * src/ds390/gen.c (genNot, genNotFloat),
7272 * src/z80/gen.c (genNot, genNotFloat),
7273 * src/pic/gen.c (genNot, genNotFloat),
7274 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

7278 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7279 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7280 during interrupts. Ensure WSAVE is located at a shared bank address.
7281 2. Fixed page selection in some places
7282 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7283 the registers name strings.
7284 4. Fixed "signed / unsigned compare" compiler warnings.
7285 5. The PIC port manages its own allocation of the general purpose
7286 registers, but makes no attempt to reuse them. As a result when
7287 compiling it soon runs out of general purpose registers. Some
7288 additional code was added to the files pcode.c and device.c to walk
7289 through the function call tree and rename the registers so that they
7299 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7300 genPlus() & genMinus() when the result is the same as left or right

7306 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7308 Made bitfield a distinct type from bit so that bitfields
7309 convert as per ANSI C and bits retain their traditional
7310 boolean style behaviour. Implemented bitfield support in
7318 * src/ds390/gen.c: bit v bitfield split
7319 * src/z80/gen.c: New support for bitfields
7320 * support/regression/tests/bitfields.c: reenabled z80,
7323 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7325 Rules 246.x, 247.x relate to bitfields, the others speed up
7326 access to xdata mapped I/O devices.
7328 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7330 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7332 Cleaned up genPackBits and genUnpackBits and added two helper
7333 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7334 for literal assignments in genPackBits (thanks to Frieder for
7340 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7342 Fixed bug #748310 (pointer to function type mishandled when the
7343 function name is omitted). Also fixed a SIGSEGV when a function
7344 attribute (reentrant, etc) is used on a non-function or on a
7345 function but misplaced before the parameter list.
7347 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7349 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7350 * support/Util/SDCCerr.h,
7351 * support/Util/SDCCerr.c: Added func attr misuse error msg

7372 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7374 Made the constant following the "interrupt" keyword optional. If
7375 omitted, the function will not automatically be given an entry
7376 in the interrupt vector table (similar to #pragma NOIV, but
7377 less syntacticly kludgy). The interrupt number is also now
7378 range checked. Also fixed a bug in the high order bit example
7385 * support/Util/SDCCerr.c
7386 * support/Util/SDCCerr.h
7389 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

7394 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7396 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7397 be re-activated by defining REDUCE_LITERALS)
7398 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7399 unsigned, but are signed by default
7400 * src/SDCCval.c (constVal): rearranged
7401 * src/SDCCval.c (valMod): preliminary fix
7402 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7854 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
7855 the regression tests I'm not brave enough to enable 245.b, 245.c
7856 * doc/sdccman.lyx: added latex preamble for hyperref package.
7857 Using pdflatex this will give you a hyperlinked pdf file with
7858 bookmarks. (prepend '%' before /usepackage if this breaks something)

7896 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
7898 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
7899 it can be defined with CFLAGS when running configure
7900 * src/SDCCmain.c: fixed compiling + linking with object files
7902 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
7904 * configure.in: configure for pic16 port,
7905 added --disable-pic16-port
7906 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7907 * src/SDCCmain.c: linkOptions is changed to set *,
7908 added if/endif conditional macros to remove options help
7909 messages from optionsTable when a port is not configured, added
7910 support for the PIc16 port in the ports table, when executing
7911 the compiler with no port specified on command line, a default
7912 port is selected with the new macro DEFAULT_PORT which is
7913 defined in port.h, in setDefaultOptions() linkOptions is removed
7914 from initialization assignment, since now it is a set,
7915 parseCmdLine uses setParseWithComma for linkOptions, in
7916 linkEdit() linkOptions are accessed with new function indexSet()
7917 which returns the i'th item of a set variable. See SDCCset.c, in
7918 linkEdit() when calling buildCmdLine(), added linkOptions as
7919 last argument. Now users can pass arguments to gplink via the
7920 -Wl option, main() uses pic16glue() to glue up pic16 programs
7921 * src/SDCCpeeph.c: various changes to support pic16

7930 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
7932 * src/pic16/glue.c: commented out some error producing lines
7933 * src/pic16/main.c: __config directives are commented out to stop
7934 gpasm complaining and test the linkage with gplink, _linkCmd and
7935 _asmCmd changed to be more gplink and gpasm friendly
7936 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7937 produced an error when parsed, peep rule 12 is added to utilize
7938 movff, but it is commented out since the pCode does not support
7939 yet a command with 2 address arguments
7941 2003-05-18 <johan AT balder>
7943 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
7944 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7970 2003-05-11 Borut Razem <borut.razem AT siol.net>
7972 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7973 the path of bin directory, so that PATH is the only env. variable, which has to be set
7974 in case of standard installation.

9004 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9006 * in \sdcc\as\mcs51\ changed these files in order to create an
9007 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9008 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9009 following files to include the previous two files: aslink.dsp,
9010 Makefile.aslink, Makefile.bcc, and Makefile.in.
9012 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9013 .adb instead of .cdb
9015 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9017 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9018 value from option --iram-size.
9020 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9022 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9025 2002-09-18 <wiml AT hhhh.org>
9027 * SDCClrange.h: exposed setFromRange() and setToRange()
9028 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9029 packRegsForAccUse() (bug 542397)
9030 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9031 multiple times and emitting the fetch operations more than once
9032 added aopGetUsesAcc() function to allow binary operators to
9033 fetch their operands in the correct order; made genMinus() emit
9034 compact code for X = LITERAL - Y
9036 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9037 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9038 sprintf() in line 1267.
9040 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9041 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9044 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9045 Changes to aslink (All the changes are marked with 'JCF'):
9047 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9050 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9051 area BSEG. Also moves, if possible, the DATA area down into the internal
9052 ram so more space is available.
9054 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9057 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9058 not bytes. Function summary() which creates a memory usage summary
9059 file with extension .mem. Reports of overlaping stack and small stack
9060 size. If the space for the stack is less than 16 bytes aslink trows a
9063 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9064 the 8051. Option 'y' for memory summary output file.
9066 Changes to sdcc (All the changes are marked with 'JCF'):
9068 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9070 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9071 overlaying area for it (uses RegBankUsed[4]).
9073 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9074 bank zero as used by default. By default aslink locates the stack
9075 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9076 the creation of the .mem file. Delegates the allocation of data area
9077 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9078 the begining of the stack area to aslink.
9080 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9081 glue() in SDCCglue.c creates an area for it.
9083 2002-09-03 Borut Razem <borut.razem AT siol.net>
9084 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9085 sdcc/src/pic/glue.c:
9086 introduced atexit() handler for teporay files removal in case of
9087 errors, assertions, ...
9089 2002-08-29 Borut Razem <borut.razem AT siol.net>
9090 * sdcc/support/cpp2/auto-host_vc_in.h:
9091 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9092 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9093 Maybe there is a similar problem with BORLANDC? It should be checked!
9095 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9096 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9097 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9098 was not executed, and the compiler (cl) launched a warning:
9099 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9101 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9102 * src/SDCCglue.c (printIvalArray): iterative calculation of array length

9107 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9108 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9109 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9110 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9111 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9112 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9113 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9114 - added Release configuration in VS projects
9115 - review of compiler an linker options
9116 - VC .exe files are generated in bin_vc directory, not to interfere
9117 with binaries generated from other projects (cygwin, mingw, bcc ...)
9119 * sdcc/src/yacc.dsp: added
9121 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9122 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9123 and insert the version number definitions from .version
9125 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9127 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

9137 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9139 2002-08-10 Borut Razem <borut.razem AT siol.net>
9140 * src/SDCCmain.c (main):
9141 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9142 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9143 The consequence was that some temporary files were not removed.
9146 unification of code in functions tempfilename() and tempfile():
9147 function tempnam() is defined in Visual Studio 6.0 and .NET
9149 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9151 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9152 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:

9157 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9158 changed project type to Generic Project so that can be correcly converted to VS.NET project
9160 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9162 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9164 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9166 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9167 added return 0 statements after assert() to make compiler happy
9169 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9170 added newline in the def file to keep MSC compiler satisfied
9172 * sdcc/src/z80/gen.c:
9173 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9174 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9175 - solved MSC error in function aopDump()
9177 * sdcc_vc.h: define PREFIX as "\\sdcc"
9179 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9180 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

9231 Initialized the new field char *Processor field to NULL in all ports
9234 Compiler generated registers for interrupt context saving
9235 were not getting allocated.
9237 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9240 Fixed left shift. Will promote the left side of a left shift
9241 if a) left shifting more than size of operand or b) when assigned
9242 to something size > size of left side
9244 2002-03-14 Scott Dattalo <scott AT dattalo.com>

9352 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
9354 * sdcc/src/SDCCloop.c:
9355 Previous fix was not good. basic blocks that have "break" or "return" are
9356 not really partof a loop , but live ranges used in these blocks should
9357 be live thru the entire loop, so set partOfLoop but don't add them to
9360 2002-02-21 <johan AT FRIJA>
9362 * src/SDCCcse.c: fixed bug #514308
9364 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

9389 Karl and Johan start ucsim XA support. Most dissassembly working,
9390 about 75% emulation done(plenty of work remaining).
9392 * sim/ucsim/z80.src:
9393 Add Z80 support to ucsim, add test-ucz80 regression test,
9394 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
