1832 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1833 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1834 always available in leading double underscore form. The C99 support is
1835 mostly missing, but it's a start.
1836 * support/regression/tests/bug-227710.c: fixed nonconforming use of

1915 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1917 * device/lib/printf_large.c: removed inline assembly for portability and
1918 readability. Use printf_fast if speed or size are more important.
1919 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1920 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1922 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1924 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1925 prevent compiler warning
1927 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1929 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1930 moved to level 0 and declared as static. Also they are explicit
1931 placed in access bank. This was necessery because some times they
1932 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1933 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1934 optimizations. Currently only compare to unsigned char is implemented,
1935 * src/pic16/gen.c: added fReturnIdx array,
1936 * (struct resolvedIfx) is moved to gen.h and made public,
1937 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1938 * (aopForSym): added an optimization to directly store in stack of
1939 the operand of a SEND iCode,
1940 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1941 but as registers instead (AOP_REG) using the fReturnIdx array,
1942 * (pic16_freeAsmop): remove the freed register from the
1943 _G.sregsAlloc field,
1944 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1945 a compare of 'WREG',
1946 * (pic16_popGetTempRegCond): changed function prototype, now
1947 function takes also a bitVector argument v which holds the current
1948 set of registers that are allocated for stack access by aopForSym,
1949 registers allocated in aopForSym for accessing stack symbols are not
1950 any more part of the functions usedRegs field,
1951 * (genCall): some times aopOp is called for a stack variable to be
1952 send, aopForSym might perform the push, if this is true make sure
1953 that genCall doesn't push the variable twice by testing _G.resDirect,
1954 * (genFunction): changed testing for unspecified interrupt number
1955 from 256 to INTNO_UNSPEC,
1956 * modified selection scheme of frame pointer generation. Previously
1957 if function did use local registers a frame pointer was generated,
1958 now a frame pointer is generated only if function has arguments
1959 (that need PLUSW2 register access), or has stack arguments, or the
1960 compiler is not instructed to omit the frame pointer,
1961 * (genEndFunction): before restoring local registers that were saved
1962 in the function preamble, also restore the registers that *might*
1963 have been allocated for stack access,
1964 * (genRet): removed some old comments,
1965 * (genCmp, the active (RN's) version): added a call to the
1966 pic16_genCmp_special function to perform the compare with a more
1967 robust and optimized way,
1968 * (genInline): a feature has been added in inline code generation,
1969 which allows a wildcard variable substitution when writing inline
1970 assembly. Code is incomplete and experimental therefore undocumented,
1971 * (genCast): changed order of aopOp for result and right to allow
1972 aopForSym to directly load the result if possible,
1973 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1974 perform an optimized compare on some selected special occasions,
1975 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1976 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1977 generate an IVT any more,
1978 * src/pic16/main.c (pic16_optionsTable): added command line option
1980 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1981 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1983 * src/pic16/NOTES: Raphael Neider added in list of active developers
1984 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1985 jumptable_end to prevent bug #,
1986 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1987 inCond and outCond fields,
1988 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1989 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1990 turn off register spilling,
1991 * (packRegsForOneUse): synced with other ports' versions although it
1992 is not used currently,
1993 * (pic16_packRegisters): added an optimization while reading
1994 structure bitfields, some registers may be saved (malloc code is
1995 decreased by 80 bytes)
1997 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1999 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2000 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2001 this can be optimized more?
2003 2005-03-10 Raphael Neider <rneider AT web.de>
2005 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2006 genNearPointerGet): (hopefully) fixed access to bitfields via
2007 pointers (p->bitN = x; and x = p->bitN; failed)

2641 Adding support for replacing ljmps with sjmps in jumptables
2642 generated for switch statements. For now you need to set the
2643 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2644 Now 4 algorithms for mcs51 jumptable generation are used:
2645 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2646 addresses loaded pc-relative for up to 112 cases and stack-pushing
2647 target addresses loaded with offset from dptr for up to 256 cases.

2673 Large cummulative patch for pic16 port.
2674 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
2675 to call when a stack overflow occurs,
2676 * (malloc.h): added CVS Id tag,
2677 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2679 * added libc directory. The current version of LibC contains string
2680 functions, ctype functions and macros and some functions of the
2681 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2682 be extensively tested in the future. Standard disclaimer here.
2683 Library is not automatically build yet. But one can build it by
2684 invoking 'make' inside the libc directory.
2685 * added ADC library under libio. Preliminary version yet.
2687 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

2694 * (genUminusFloat): fixed for pic16, ported code from mcs51,
2695 * (pic16_storeForReturn): optimized return of 0,
2696 * (genCmp): experimental code for new genCmp which uses PIC18's
2697 special compare&skip instructions. Initial tests fail some times
2698 with variables grater than 1 byte in size, so new code is disabled,
2699 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2701 * (genCast): began a fix to optimize the casting of a bit to another
2702 bit, now assigning a bitfield to another bitfield will fail, sorry,
2703 * src/pic16/main.c: disabled the use of lr-support feature,
2704 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
2705 * added some function prototypes, added function _debugf prototype,

2707 bits with offset (case PO_GPR_BIT),
2708 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
2710 * (isBankInstruction): modified to return 0 for no banking instruction,
2711 and 1 for banking instruction,
2712 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2713 caused stop processing pCodes after a inline assembly block,
2714 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
2715 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
2716 registers when it shouldn't,
2717 * src/pic16/ralloc.c (allocReg): add preliminary support for
2718 supporting a limited set of temporary registers,
2720 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2722 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
2723 genDataPointerSet): ensure assignments always copy in MSB to LSB
2725 (loadRegFromAop): recognize CLRH optimization,
2726 (genFunction): optimize RECEIVE iCodes in reentrant functions
2728 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2730 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

2744 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
2746 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

5725 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5727 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5728 loaded with the linker search paths (-L arguments) and the libraries
5729 to be linked with the current source (-l arguments). Changes
5730 currently will affect only the pic16 port.
5731 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5732 include path the port specific paths and port specific libraries,
5733 * gplink command now contains the $3 argument,
5734 * src/pic16/device.h,
5735 * src/pic16/device.c,: structure PIC_device is made public and
5736 renamed to PIC16_device, the same for variable Pics which is renamed
5737 to Pics16. Updated all references to them.
5738 * src/pic16/glue.c (pic16glue): corrected bug with code
5739 initialization which bypassed the variable initializations block.

5749 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
5751 Documenting changes from previous commits.
5752 * configure.in (version 1.56),
5753 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5754 when generating output files to configure the pic16 library,
5755 but now I've commented it out, since gputils aren't installed in the
5756 SF compile farm, so library won't compile
5758 * device/lib/Makefile.in (version 1.56): initially I've added in
5759 target 'all' the prerequestive 'model-pic16' so it compiled the
5760 pic16 library, but now I've commented it out for the same reasons
5762 * added targets 'model-pic16' and 'objects-pic16' to compile the
5764 * added target 'port-specific-objects-pic16' to handle the
5765 generated libraries and copy them into the build/ directory
5766 * added target 'clean-intermediate-pic16' to clean intermediate
5767 files into pic16 directory
5768 * in target 'installdirs' added line to create directory pic16 in
5769 the installation path
5771 * device/include/Makefile.in (version 1.11): in target 'install'
5772 added lines to copy all header files to installation path,
5773 * in target 'installdirs' added line create directory for pic16
5774 headers in the installation path

5789 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5790 option so that it actually works. Made it specific to the z80, since
5791 the gbz80 doesn't have these kinds of I/O ports.
5793 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5795 * device/include/z180.h,

5808 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5810 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
5811 changed interrupt vector table generation to only emit declared vectors.
5812 * device/include/Makefile.in: added missing backslash
5813 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)

5817 Mainly changes to support compilation of the device libraries
5818 * src/pic16/device.c: stack is allocated via symbol and not
5819 via literal number. The symbol is placed in the corresponding
5820 position of the data ram
5821 * (pic16_dump_section): relocatable and absolute uninitialized
5822 data are now emitted in sorted order to reduce section naming,
5823 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5824 weren't marked as being in the access bank,
5826 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5828 Added portion of GNU PIC Library under the directory
5829 device/include/pic16 and device/lib/pic16. These files
5830 contain the declarations of SFRs for the PIC18Fxx2 devices.
5831 The directory is initialized via configure from toplevel.
5833 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
5835 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
5836 the spilllocations to be compared correctly
5838 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
5840 * src/SDCCast.c (decorateType): fixed bug introduced today
5842 2004-01-12 Borut Razem <borut.razem AT siol.net>
5844 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

5847 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
5849 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
5850 in simpler and even better code
5852 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
5854 * src/SDCCicode.c (operandOperation): fixed bug #874819

5860 * doc/sdccman.lyx: Moved and added some sections, small changes
5861 all over. Telling LaTeX to be less strict with word spacing
5862 to better keep the right margin. Changed some notes about
5863 maintainance of the ports in section 3.2.1 - is it OK like this?
5865 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5902 UPPER for immediate operands,
5903 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5905 * src/pic16/peeph.def: all peepholes with movff are commented out,
5906 because there is a problem in the pcode peep optimizer,
5907 * src/pic16/ralloc.c: the register allocator can now reuse local
5908 function symbols for another function. This saves register usage.
5909 * src/pic16/ralloc.h: added flag isLocal in structure regs,
5911 Added file src/pic16/NOTES with information about program writing on
5912 the current port version.

5941 gen51Code): more efficient parameter receive for --model-large
5944 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5947 * src/z80/main.c: added missed needLinkerScript flags (more than
5948 one port structure defined in these file)
5949 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

5972 directive when no overlay data exist
5973 * (picglue): modified to emit uninitialized data segment
5974 according to udata_section_name

5980 * src/pic16/main.c: added $l in _asmCmd, changed extension for
5981 object file from '.rel' to '.o' in port->linker structure,

5984 2004-01-07 Borut Razem <borut.razem AT siol.net>
5986 * support/scripts/sdcc.nsi: update PATH
5987 * support/scripts/sdcc.ico: craeted

6000 include information about variables allocated to the overlay
6003 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6005 * as/mcs51/lkmain.c: Help about -Y option

6017 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6019 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6020 (default behaviour).
6022 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6024 A python script to validate compiler diagnostic messages. It can be
6025 used to verify that sdcc complains about bad c source code and
6026 gives a good location of the error.
6027 * support/valdiag/Makefile,
6028 * support/valdiag/valdiag.py,
6029 * support/valdiag/tests/*
6031 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6044 * src/common.h: added ifndef/define/endif macros
6045 around the header file.
6046 Bug reported from Jesus Calvino-Fraga
6048 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6050 * sdcc.spec: updated
6051 * device/include/Makefile.in: don't install CVS directories
6052 * device/lib/Makefile.in: added removal of CVS directories after install
6053 * doc/Makefile: fixed install, added local_icons
6054 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6055 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6056 * src/ds390/gen.c (genRightShift): fixed bug #870788
6057 * src/SDCCast.c (decorateType): fixed bug #870781
6059 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6061 PIC16 port related changes:
6062 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6063 added variable stackPos,
6065 * gen.c: genCall, assignResultValue: added support for
6066 pushing/retrieving function parameters to/from stack,
6067 genFunction,genEndFunction: setup stack frame for the
6069 genAddrOf: will be changed according to bug 863624
6071 * added files genutils.c and genutils.h which contain gen*
6072 debugged and optimised functions extracted from gen.c
6074 * glue.c: added variable 'externs' which holds extern symbols,
6075 pic16emitRegularMap: is modified to properly handle relocatable
6076 symbols under the new scheme,
6077 pic16createInterruptVect: is modified
6078 pic16printPublics: is modified to emit 'global' assembler directives,
6079 added pic16_printExterns to print extern symbols,
6080 pic16glue: initializes stack/frame pointer in the beginning of
6081 the assembly output. Temporary hack, will be corrected later,
6082 because gplink yet does not support stack and SDCC does not
6083 yet support a type of crt0.o object to create the final binary.
6085 * Removed many lines that contain 8051 legacy code.
6086 * The code is finally placed under a 'code' directive.
6087 * Added port specific options.
6089 * _process_pragma: simplified since now we do not need *special*
6090 include file to define SFR registers. But a separate header
6091 will be needed. This will be developed later.
6092 * _pic16_parseOptions: added, parses port specific options:
6093 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6094 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6095 --preplace-udata-with=
6097 * _pic16_setDefaultOptions: modified to initialize section names,
6098 but hack is temporarly out of order since it needs improvement.
6099 * _pic16_genAssemblerPreamble: configuration words are emitted by
6100 their address instead of their name. This part is incomplete and
6101 supports only the 18Fxx2 devices. Other devices will emit an error
6102 during assembly since they do not contain the same set of config
6104 * _pic16_genIVT: is modified,
6106 * pcode.c: added definitions for some hardware registers that are needed
6108 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6109 All PCI entries are updated. Now LFSR is supported.
6110 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6111 * added pic16_newpCodeOpLit2 to support instructions with
6112 two literal arguments
6113 * pic16_pCode2str: corrected code that emits assembler instructions
6114 with two literal operands and those that have an access bit modifier
6115 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6116 this fixes a bug which caused some labels to be lost, when an
6117 assembler directive was added, i.e. banksel,
6118 * pic16_FixRegisterBanking: improved logic that causes the insertion
6120 * InlineFunction: functions that are called once, are not any more
6121 inlined. This can be a port option in the future,
6123 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6125 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6126 hold the corresponding uninitialized symbols,
6127 * pic16_allocProcessorRegister: registers have explicit marked the
6129 * pic16_allocInternalRegister: registers are explicit marked as
6131 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6132 processing list, so bit registers were lost,
6135 * ralloc.h: added field 'accessBank' and original symbol operand
6136 in register definition,
6137 * removed the field isMapped from register definition,
6139 ** Several functions have been removed from various sources:
6140 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6141 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6142 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6143 pic16_assignRelocatableRegisters
6145 ** others have been introduced:
6146 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6147 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6149 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6151 * support/scripts/inc2h.pl: changed definition of BIT_AT
6152 to emit 'sbit at' instead of 'bit at'. This was a request.
6154 PIC16 port related preliminary changes:
6155 * gen.c: prefixed function popRegFromString with
6156 pic16_ and all references to it corrected
6157 * pcode.c: all pic16_pc_* hardware registers prefixed
6158 with underscore (_),
6159 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6160 * ralloc.c: newReg(): when register is REG_SFR then
6161 set address to rIdx,
6162 pic16_allocProcessorRegister(): marks register wasUsed=0
6163 pic16_writeUsedRegs(): added a call to assign processor
6164 registers via pic16_assignFixedRegisters
6166 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6168 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6169 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6170 variables in unused register banks. Also the SSEG is placed
6171 wherever there is enough space for it, and IDATA can be anywhere
6172 in internal RAM. For now compile using -Wl-Y[stack_size].
6173 The mem file is different for this option as well, since it

7172 iCode properly now. Use getSize instead of nRegs since a & b
7173 aren't part of the nRegs tally.
7175 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
7177 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()
7178 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
7179 before instructions that use the _STATUS register
7181 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
7183 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
7184 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7185 fetching of the pointer
7186 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7187 copied from genNearPointerSet()
7188 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7189 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
7190 If they pop r0/r1 they must be called in the opposite order than aopOp().
7191 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
7192 (resp. --stack-auto), prepared for --xstack

7203 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7205 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7206 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7207 type for bits was changed. It resulted in bit variables becoming
7208 global, which is not permitted in PIC 14 assembly output.
7210 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7212 * doc/sdccman.lyx: various additions and updates. Rearranged sections
7214 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7216 Z80 and MCS51 linkers complaint if a public symbol is defined

7225 A few small changes that speed up the peephole optimizer.
7229 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7231 Try to make the peephole optimizer smarter by maintaining
7232 an association between the assembly source code and the
7233 iCodes that originated them. Put this information to use
7234 with a new peephole rule condition "notVolatile" so that
7235 the rules can be aggressive yet still safe.
7240 * src/mcs51/peeph.def
7242 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7246 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7247 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7248 if the left or right operand symbols have the accuse flag set.
7250 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7252 Changed the type of the result of the ! (NOT) operator to char;
7253 previously it returned the same type as the source. This allows
7254 us to eliminate all the genFloatNot functions (all of its target
7255 implementations were very buggy) since !float can use the same
7258 * src/SDCCicode.c (ast2iCode): ! returns char
7259 * src/mcs51/gen.c (genNot, genNotFloat),
7260 * src/ds390/gen.c (genNot, genNotFloat),
7261 * src/z80/gen.c (genNot, genNotFloat),
7262 * src/pic/gen.c (genNot, genNotFloat),
7263 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

7267 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7268 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7269 during interrupts. Ensure WSAVE is located at a shared bank address.
7270 2. Fixed page selection in some places
7271 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7272 the registers name strings.
7273 4. Fixed "signed / unsigned compare" compiler warnings.
7274 5. The PIC port manages its own allocation of the general purpose
7275 registers, but makes no attempt to reuse them. As a result when
7276 compiling it soon runs out of general purpose registers. Some
7277 additional code was added to the files pcode.c and device.c to walk
7278 through the function call tree and rename the registers so that they
7288 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7289 genPlus() & genMinus() when the result is the same as left or right

7295 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7297 Made bitfield a distinct type from bit so that bitfields
7298 convert as per ANSI C and bits retain their traditional
7299 boolean style behaviour. Implemented bitfield support in
7307 * src/ds390/gen.c: bit v bitfield split
7308 * src/z80/gen.c: New support for bitfields
7309 * support/regression/tests/bitfields.c: reenabled z80,
7312 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7314 Rules 246.x, 247.x relate to bitfields, the others speed up
7315 access to xdata mapped I/O devices.
7317 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7319 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7321 Cleaned up genPackBits and genUnpackBits and added two helper
7322 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7323 for literal assignments in genPackBits (thanks to Frieder for
7329 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7331 Fixed bug #748310 (pointer to function type mishandled when the
7332 function name is omitted). Also fixed a SIGSEGV when a function
7333 attribute (reentrant, etc) is used on a non-function or on a
7334 function but misplaced before the parameter list.
7336 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7338 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7339 * support/Util/SDCCerr.h,
7340 * support/Util/SDCCerr.c: Added func attr misuse error msg

7361 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7363 Made the constant following the "interrupt" keyword optional. If
7364 omitted, the function will not automatically be given an entry
7365 in the interrupt vector table (similar to #pragma NOIV, but
7366 less syntacticly kludgy). The interrupt number is also now
7367 range checked. Also fixed a bug in the high order bit example
7374 * support/Util/SDCCerr.c
7375 * support/Util/SDCCerr.h
7378 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

7381 * src/SDCCicode.c (operandOperation): rewritten some ops
7382 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7383 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7385 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7386 be re-activated by defining REDUCE_LITERALS)
7387 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7388 unsigned, but are signed by default
7389 * src/SDCCval.c (constVal): rearranged
7390 * src/SDCCval.c (valMod): preliminary fix
7391 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7843 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
7844 the regression tests I'm not brave enough to enable 245.b, 245.c
7845 * doc/sdccman.lyx: added latex preamble for hyperref package.
7846 Using pdflatex this will give you a hyperlinked pdf file with
7847 bookmarks. (prepend '%' before /usepackage if this breaks something)

7885 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
7887 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
7888 it can be defined with CFLAGS when running configure
7889 * src/SDCCmain.c: fixed compiling + linking with object files
7891 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

7894 added --disable-pic16-port
7895 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7896 * src/SDCCmain.c: linkOptions is changed to set *,
7897 added if/endif conditional macros to remove options help
7898 messages from optionsTable when a port is not configured, added
7899 support for the PIc16 port in the ports table, when executing
7900 the compiler with no port specified on command line, a default
7901 port is selected with the new macro DEFAULT_PORT which is
7902 defined in port.h, in setDefaultOptions() linkOptions is removed
7903 from initialization assignment, since now it is a set,
7904 parseCmdLine uses setParseWithComma for linkOptions, in
7905 linkEdit() linkOptions are accessed with new function indexSet()
7906 which returns the i'th item of a set variable. See SDCCset.c, in
7907 linkEdit() when calling buildCmdLine(), added linkOptions as
7908 last argument. Now users can pass arguments to gplink via the
7909 -Wl option, main() uses pic16glue() to glue up pic16 programs
7910 * src/SDCCpeeph.c: various changes to support pic16

7921 * src/pic16/glue.c: commented out some error producing lines
7922 * src/pic16/main.c: __config directives are commented out to stop
7923 gpasm complaining and test the linkage with gplink, _linkCmd and
7924 _asmCmd changed to be more gplink and gpasm friendly
7925 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7926 produced an error when parsed, peep rule 12 is added to utilize
7927 movff, but it is commented out since the pCode does not support
7928 yet a command with 2 address arguments
7930 2003-05-18 <johan AT balder>
7932 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
7933 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7959 2003-05-11 Borut Razem <borut.razem AT siol.net>
7961 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7962 the path of bin directory, so that PATH is the only env. variable, which has to be set
7963 in case of standard installation.
7964 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

8993 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8995 * in \sdcc\as\mcs51\ changed these files in order to create an
8996 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8997 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8998 following files to include the previous two files: aslink.dsp,
8999 Makefile.aslink, Makefile.bcc, and Makefile.in.
9001 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9002 .adb instead of .cdb
9004 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9006 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9007 value from option --iram-size.
9009 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9011 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9014 2002-09-18 <wiml AT hhhh.org>
9016 * SDCClrange.h: exposed setFromRange() and setToRange()
9017 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9018 packRegsForAccUse() (bug 542397)
9019 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9020 multiple times and emitting the fetch operations more than once
9021 added aopGetUsesAcc() function to allow binary operators to
9022 fetch their operands in the correct order; made genMinus() emit
9023 compact code for X = LITERAL - Y
9025 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9026 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9027 sprintf() in line 1267.
9029 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9030 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9033 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9034 Changes to aslink (All the changes are marked with 'JCF'):
9036 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9039 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9040 area BSEG. Also moves, if possible, the DATA area down into the internal
9041 ram so more space is available.
9043 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9046 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9047 not bytes. Function summary() which creates a memory usage summary
9048 file with extension .mem. Reports of overlaping stack and small stack
9049 size. If the space for the stack is less than 16 bytes aslink trows a
9052 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9053 the 8051. Option 'y' for memory summary output file.
9055 Changes to sdcc (All the changes are marked with 'JCF'):
9057 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9059 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9060 overlaying area for it (uses RegBankUsed[4]).
9062 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9063 bank zero as used by default. By default aslink locates the stack
9064 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9065 the creation of the .mem file. Delegates the allocation of data area
9066 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9067 the begining of the stack area to aslink.
9069 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9070 glue() in SDCCglue.c creates an area for it.
9072 2002-09-03 Borut Razem <borut.razem AT siol.net>
9073 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9074 sdcc/src/pic/glue.c:
9075 introduced atexit() handler for teporay files removal in case of
9076 errors, assertions, ...
9078 2002-08-29 Borut Razem <borut.razem AT siol.net>
9079 * sdcc/support/cpp2/auto-host_vc_in.h:
9080 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9081 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9082 Maybe there is a similar problem with BORLANDC? It should be checked!
9084 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9085 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9086 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9087 was not executed, and the compiler (cl) launched a warning:
9088 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9090 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>

9094 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9096 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9097 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9098 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9099 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9100 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9101 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9102 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9103 - added Release configuration in VS projects
9104 - review of compiler an linker options
9105 - VC .exe files are generated in bin_vc directory, not to interfere
9106 with binaries generated from other projects (cygwin, mingw, bcc ...)
9108 * sdcc/src/yacc.dsp: added
9110 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9111 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9112 and insert the version number definitions from .version
9114 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9116 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

9126 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9128 2002-08-10 Borut Razem <borut.razem AT siol.net>
9129 * src/SDCCmain.c (main):
9130 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9131 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9132 The consequence was that some temporary files were not removed.
9135 unification of code in functions tempfilename() and tempfile():
9136 function tempnam() is defined in Visual Studio 6.0 and .NET
9138 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9140 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9141 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9142 - removed compiler command line option /WX: Treats all warnings as errors
9143 - update a list of source files, included into the project
9145 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,

9155 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9156 added return 0 statements after assert() to make compiler happy
9158 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9159 added newline in the def file to keep MSC compiler satisfied
9161 * sdcc/src/z80/gen.c:
9162 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9163 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9164 - solved MSC error in function aopDump()
9166 * sdcc_vc.h: define PREFIX as "\\sdcc"
9168 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

9220 Initialized the new field char *Processor field to NULL in all ports
9223 Compiler generated registers for interrupt context saving
9224 were not getting allocated.
9226 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9229 Fixed left shift. Will promote the left side of a left shift
9230 if a) left shifting more than size of operand or b) when assigned
9231 to something size > size of left side
9233 2002-03-14 Scott Dattalo <scott AT dattalo.com>

9341 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
9343 * sdcc/src/SDCCloop.c:
9344 Previous fix was not good. basic blocks that have "break" or "return" are
9345 not really partof a loop , but live ranges used in these blocks should
9346 be live thru the entire loop, so set partOfLoop but don't add them to
9349 2002-02-21 <johan AT FRIJA>
