1851 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
1852 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1853 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1854 always available in leading double underscore form. The C99 support is
1855 mostly missing, but it's a start.
1856 * support/regression/tests/bug-227710.c: fixed nonconforming use of
1857 reserved identifier "__data".

1935 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1937 * device/lib/printf_large.c: removed inline assembly for portability and
1938 readability. Use printf_fast if speed or size are more important.
1939 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1940 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1942 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1944 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1945 prevent compiler warning
1947 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1949 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1950 moved to level 0 and declared as static. Also they are explicit
1951 placed in access bank. This was necessery because some times they
1952 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1953 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1954 optimizations. Currently only compare to unsigned char is implemented,
1955 * src/pic16/gen.c: added fReturnIdx array,
1956 * (struct resolvedIfx) is moved to gen.h and made public,
1957 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1958 * (aopForSym): added an optimization to directly store in stack of
1959 the operand of a SEND iCode,
1960 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1961 but as registers instead (AOP_REG) using the fReturnIdx array,
1962 * (pic16_freeAsmop): remove the freed register from the
1963 _G.sregsAlloc field,
1964 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1965 a compare of 'WREG',
1966 * (pic16_popGetTempRegCond): changed function prototype, now
1967 function takes also a bitVector argument v which holds the current
1968 set of registers that are allocated for stack access by aopForSym,
1969 registers allocated in aopForSym for accessing stack symbols are not
1970 any more part of the functions usedRegs field,
1971 * (genCall): some times aopOp is called for a stack variable to be
1972 send, aopForSym might perform the push, if this is true make sure
1973 that genCall doesn't push the variable twice by testing _G.resDirect,
1974 * (genFunction): changed testing for unspecified interrupt number
1975 from 256 to INTNO_UNSPEC,
1976 * modified selection scheme of frame pointer generation. Previously
1977 if function did use local registers a frame pointer was generated,
1978 now a frame pointer is generated only if function has arguments
1979 (that need PLUSW2 register access), or has stack arguments, or the
1980 compiler is not instructed to omit the frame pointer,
1981 * (genEndFunction): before restoring local registers that were saved
1982 in the function preamble, also restore the registers that *might*
1983 have been allocated for stack access,
1984 * (genRet): removed some old comments,
1985 * (genCmp, the active (RN's) version): added a call to the
1986 pic16_genCmp_special function to perform the compare with a more
1987 robust and optimized way,
1988 * (genInline): a feature has been added in inline code generation,
1989 which allows a wildcard variable substitution when writing inline
1990 assembly. Code is incomplete and experimental therefore undocumented,
1991 * (genCast): changed order of aopOp for result and right to allow
1992 aopForSym to directly load the result if possible,
1993 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1994 perform an optimized compare on some selected special occasions,
1995 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1996 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1997 generate an IVT any more,
1998 * src/pic16/main.c (pic16_optionsTable): added command line option
2000 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2001 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2003 * src/pic16/NOTES: Raphael Neider added in list of active developers
2004 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2005 jumptable_end to prevent bug #,
2006 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2007 inCond and outCond fields,
2008 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2009 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2010 turn off register spilling,
2011 * (packRegsForOneUse): synced with other ports' versions although it
2012 is not used currently,
2013 * (pic16_packRegisters): added an optimization while reading
2014 structure bitfields, some registers may be saved (malloc code is
2015 decreased by 80 bytes)
2017 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2019 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2020 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2021 this can be optimized more?
2023 2005-03-10 Raphael Neider <rneider AT web.de>
2025 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2026 genNearPointerGet): (hopefully) fixed access to bitfields via
2027 pointers (p->bitN = x; and x = p->bitN; failed)

2661 Adding support for replacing ljmps with sjmps in jumptables
2662 generated for switch statements. For now you need to set the
2663 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2664 Now 4 algorithms for mcs51 jumptable generation are used:
2665 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2666 addresses loaded pc-relative for up to 112 cases and stack-pushing
2667 target addresses loaded with offset from dptr for up to 256 cases.

2694 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
2695 to call when a stack overflow occurs,
2696 * (malloc.h): added CVS Id tag,
2697 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2699 * added libc directory. The current version of LibC contains string
2700 functions, ctype functions and macros and some functions of the
2701 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2702 be extensively tested in the future. Standard disclaimer here.
2703 Library is not automatically build yet. But one can build it by
2704 invoking 'make' inside the libc directory.
2705 * added ADC library under libio. Preliminary version yet.
2707 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

2714 * (genUminusFloat): fixed for pic16, ported code from mcs51,
2715 * (pic16_storeForReturn): optimized return of 0,
2716 * (genCmp): experimental code for new genCmp which uses PIC18's
2717 special compare&skip instructions. Initial tests fail some times
2718 with variables grater than 1 byte in size, so new code is disabled,
2719 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2721 * (genCast): began a fix to optimize the casting of a bit to another
2722 bit, now assigning a bitfield to another bitfield will fail, sorry,
2723 * src/pic16/main.c: disabled the use of lr-support feature,
2724 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

2727 bits with offset (case PO_GPR_BIT),
2728 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
2730 * (isBankInstruction): modified to return 0 for no banking instruction,
2731 and 1 for banking instruction,
2732 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2733 caused stop processing pCodes after a inline assembly block,
2734 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
2735 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
2736 registers when it shouldn't,
2737 * src/pic16/ralloc.c (allocReg): add preliminary support for
2738 supporting a limited set of temporary registers,
2740 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2742 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
2743 genDataPointerSet): ensure assignments always copy in MSB to LSB
2745 (loadRegFromAop): recognize CLRH optimization,
2746 (genFunction): optimize RECEIVE iCodes in reentrant functions
2748 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2750 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

5695 * src/pic/pcoderegs.c,
5697 * src/pic/ralloc.h: applied patch from Slade Rich;
5698 added support for multiple code pages and multiple RAM banks on the
5699 PIC 14 port. The ASM files now no longer simply assume all the
5700 code / RAM are in the same page / bank. This means the linker can
5701 safely allocate code/RAM of separate ASM files to different pages/banks.
5702 * doc/sdccman.lyx: added Slade's tips
5703 * src/mcs51/peeph.def: fixed bug #880768

5712 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
5715 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
5716 strtof is not part of C89 and isn't included with Mac OS X.
5718 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5720 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,
5721 shiftL2Left2Result): fixed bug #879326
5722 (genAnd, genOr, genXor): fixed bug when result was of type AOP_CRY

5745 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5747 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5748 loaded with the linker search paths (-L arguments) and the libraries
5749 to be linked with the current source (-l arguments). Changes
5750 currently will affect only the pic16 port.
5751 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5752 include path the port specific paths and port specific libraries,
5753 * gplink command now contains the $3 argument,
5754 * src/pic16/device.h,
5755 * src/pic16/device.c,: structure PIC_device is made public and
5756 renamed to PIC16_device, the same for variable Pics which is renamed
5757 to Pics16. Updated all references to them.
5758 * src/pic16/glue.c (pic16glue): corrected bug with code
5759 initialization which bypassed the variable initializations block.
5761 * device/lib/pic16/Makefile.rules: removed --penable-stack from
5762 COMPILE_FLAGS and added the --nostdinc option
5764 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5769 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
5771 Documenting changes from previous commits.
5772 * configure.in (version 1.56),
5773 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5774 when generating output files to configure the pic16 library,
5775 but now I've commented it out, since gputils aren't installed in the
5776 SF compile farm, so library won't compile
5778 * device/lib/Makefile.in (version 1.56): initially I've added in
5779 target 'all' the prerequestive 'model-pic16' so it compiled the
5780 pic16 library, but now I've commented it out for the same reasons
5782 * added targets 'model-pic16' and 'objects-pic16' to compile the
5784 * added target 'port-specific-objects-pic16' to handle the
5785 generated libraries and copy them into the build/ directory
5786 * added target 'clean-intermediate-pic16' to clean intermediate
5787 files into pic16 directory
5788 * in target 'installdirs' added line to create directory pic16 in
5789 the installation path
5791 * device/include/Makefile.in (version 1.11): in target 'install'
5792 added lines to copy all header files to installation path,
5793 * in target 'installdirs' added line create directory for pic16
5794 headers in the installation path

5809 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5810 option so that it actually works. Made it specific to the z80, since
5811 the gbz80 doesn't have these kinds of I/O ports.
5813 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5815 * device/include/z180.h,

5837 Mainly changes to support compilation of the device libraries
5838 * src/pic16/device.c: stack is allocated via symbol and not
5839 via literal number. The symbol is placed in the corresponding
5840 position of the data ram
5841 * (pic16_dump_section): relocatable and absolute uninitialized
5842 data are now emitted in sorted order to reduce section naming,
5843 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5844 weren't marked as being in the access bank,
5846 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5848 Added portion of GNU PIC Library under the directory
5849 device/include/pic16 and device/lib/pic16. These files
5850 contain the declarations of SFRs for the PIC18Fxx2 devices.
5851 The directory is initialized via configure from toplevel.
5853 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
5855 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

5865 doc/sdccman.lyx: upper case pragmas are deprecated
5867 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
5869 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
5870 in simpler and even better code

5881 all over. Telling LaTeX to be less strict with word spacing
5882 to better keep the right margin. Changed some notes about
5883 maintainance of the ports in section 3.2.1 - is it OK like this?
5885 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5923 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5925 * src/pic16/peeph.def: all peepholes with movff are commented out,
5926 because there is a problem in the pcode peep optimizer,
5927 * src/pic16/ralloc.c: the register allocator can now reuse local

6042 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6044 A python script to validate compiler diagnostic messages. It can be
6045 used to verify that sdcc complains about bad c source code and
6046 gives a good location of the error.
6047 * support/valdiag/Makefile,
6048 * support/valdiag/valdiag.py,
6049 * support/valdiag/tests/*

6079 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6081 PIC16 port related changes:
6082 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6083 added variable stackPos,
6085 * gen.c: genCall, assignResultValue: added support for
6086 pushing/retrieving function parameters to/from stack,
6087 genFunction,genEndFunction: setup stack frame for the
6089 genAddrOf: will be changed according to bug 863624
6091 * added files genutils.c and genutils.h which contain gen*
6092 debugged and optimised functions extracted from gen.c
6094 * glue.c: added variable 'externs' which holds extern symbols,
6095 pic16emitRegularMap: is modified to properly handle relocatable
6096 symbols under the new scheme,
6097 pic16createInterruptVect: is modified
6098 pic16printPublics: is modified to emit 'global' assembler directives,
6099 added pic16_printExterns to print extern symbols,
6100 pic16glue: initializes stack/frame pointer in the beginning of
6101 the assembly output. Temporary hack, will be corrected later,
6102 because gplink yet does not support stack and SDCC does not
6103 yet support a type of crt0.o object to create the final binary.
6105 * Removed many lines that contain 8051 legacy code.
6106 * The code is finally placed under a 'code' directive.
6107 * Added port specific options.
6109 * _process_pragma: simplified since now we do not need *special*
6110 include file to define SFR registers. But a separate header
6111 will be needed. This will be developed later.
6112 * _pic16_parseOptions: added, parses port specific options:
6113 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6114 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6115 --preplace-udata-with=
6117 * _pic16_setDefaultOptions: modified to initialize section names,
6118 but hack is temporarly out of order since it needs improvement.
6119 * _pic16_genAssemblerPreamble: configuration words are emitted by
6120 their address instead of their name. This part is incomplete and
6121 supports only the 18Fxx2 devices. Other devices will emit an error
6122 during assembly since they do not contain the same set of config
6124 * _pic16_genIVT: is modified,
6126 * pcode.c: added definitions for some hardware registers that are needed
6128 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6129 All PCI entries are updated. Now LFSR is supported.
6130 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6131 * added pic16_newpCodeOpLit2 to support instructions with
6132 two literal arguments
6133 * pic16_pCode2str: corrected code that emits assembler instructions
6134 with two literal operands and those that have an access bit modifier
6135 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6136 this fixes a bug which caused some labels to be lost, when an
6137 assembler directive was added, i.e. banksel,
6138 * pic16_FixRegisterBanking: improved logic that causes the insertion
6140 * InlineFunction: functions that are called once, are not any more
6141 inlined. This can be a port option in the future,
6143 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6145 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6146 hold the corresponding uninitialized symbols,
6147 * pic16_allocProcessorRegister: registers have explicit marked the
6149 * pic16_allocInternalRegister: registers are explicit marked as
6151 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6152 processing list, so bit registers were lost,
6155 * ralloc.h: added field 'accessBank' and original symbol operand
6156 in register definition,
6157 * removed the field isMapped from register definition,
6159 ** Several functions have been removed from various sources:
6160 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6161 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6162 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6163 pic16_assignRelocatableRegisters
6165 ** others have been introduced:
6166 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6167 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6169 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6171 * support/scripts/inc2h.pl: changed definition of BIT_AT
6172 to emit 'sbit at' instead of 'bit at'. This was a request.
6174 PIC16 port related preliminary changes:
6175 * gen.c: prefixed function popRegFromString with
6176 pic16_ and all references to it corrected
6177 * pcode.c: all pic16_pc_* hardware registers prefixed
6178 with underscore (_),
6179 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6180 * ralloc.c: newReg(): when register is REG_SFR then
6181 set address to rIdx,
6182 pic16_allocProcessorRegister(): marks register wasUsed=0
6183 pic16_writeUsedRegs(): added a call to assign processor
6184 registers via pic16_assignFixedRegisters
6186 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6188 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6189 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6190 variables in unused register banks. Also the SSEG is placed
6191 wherever there is enough space for it, and IDATA can be anywhere
6192 in internal RAM. For now compile using -Wl-Y[stack_size].
6193 The mem file is different for this option as well, since it
6194 makes no sense of talking about DSEG lenght.
6196 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6198 * src/SDCClrange.c: fixed bug 869095 that caused segfault

6445 it breaks with bitfields, extern declarations, and gcse analysis.
6446 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
6447 could be assigned through a pointer, so don't complain.

7189 and JUMPTABLE iCodes properly now (worked by accident before)
7190 * src/mcs51/gen.c (leftRightUseAcc),
7191 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
7192 iCode properly now. Use getSize instead of nRegs since a & b
7193 aren't part of the nRegs tally.
7195 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
7197 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

7201 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
7203 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
7204 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7205 fetching of the pointer
7206 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7207 copied from genNearPointerSet()
7208 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7209 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
7210 If they pop r0/r1 they must be called in the opposite order than aopOp().
7211 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
7212 (resp. --stack-auto), prepared for --xstack

7223 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7225 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7226 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7227 type for bits was changed. It resulted in bit variables becoming
7228 global, which is not permitted in PIC 14 assembly output.
7230 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7232 * doc/sdccman.lyx: various additions and updates. Rearranged sections

7245 A few small changes that speed up the peephole optimizer.
7249 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7251 Try to make the peephole optimizer smarter by maintaining
7252 an association between the assembly source code and the
7253 iCodes that originated them. Put this information to use
7254 with a new peephole rule condition "notVolatile" so that
7255 the rules can be aggressive yet still safe.
7260 * src/mcs51/peeph.def
7262 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7266 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7267 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7268 if the left or right operand symbols have the accuse flag set.
7270 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7272 Changed the type of the result of the ! (NOT) operator to char;
7273 previously it returned the same type as the source. This allows
7274 us to eliminate all the genFloatNot functions (all of its target
7275 implementations were very buggy) since !float can use the same
7278 * src/SDCCicode.c (ast2iCode): ! returns char
7279 * src/mcs51/gen.c (genNot, genNotFloat),
7280 * src/ds390/gen.c (genNot, genNotFloat),
7281 * src/z80/gen.c (genNot, genNotFloat),
7282 * src/pic/gen.c (genNot, genNotFloat),
7283 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
7285 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
7287 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7288 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7289 during interrupts. Ensure WSAVE is located at a shared bank address.
7290 2. Fixed page selection in some places
7291 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7292 the registers name strings.
7293 4. Fixed "signed / unsigned compare" compiler warnings.
7294 5. The PIC port manages its own allocation of the general purpose
7295 registers, but makes no attempt to reuse them. As a result when
7296 compiling it soon runs out of general purpose registers. Some
7297 additional code was added to the files pcode.c and device.c to walk
7298 through the function call tree and rename the registers so that they
7308 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7309 genPlus() & genMinus() when the result is the same as left or right

7315 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7317 Made bitfield a distinct type from bit so that bitfields
7318 convert as per ANSI C and bits retain their traditional
7319 boolean style behaviour. Implemented bitfield support in
7327 * src/ds390/gen.c: bit v bitfield split
7328 * src/z80/gen.c: New support for bitfields
7329 * support/regression/tests/bitfields.c: reenabled z80,
7332 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7334 Rules 246.x, 247.x relate to bitfields, the others speed up
7335 access to xdata mapped I/O devices.
7337 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7339 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7341 Cleaned up genPackBits and genUnpackBits and added two helper
7342 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7343 for literal assignments in genPackBits (thanks to Frieder for
7349 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7351 Fixed bug #748310 (pointer to function type mishandled when the
7352 function name is omitted). Also fixed a SIGSEGV when a function
7353 attribute (reentrant, etc) is used on a non-function or on a
7354 function but misplaced before the parameter list.
7356 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7358 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7359 * support/Util/SDCCerr.h,
7360 * support/Util/SDCCerr.c: Added func attr misuse error msg

7381 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7383 Made the constant following the "interrupt" keyword optional. If
7384 omitted, the function will not automatically be given an entry
7385 in the interrupt vector table (similar to #pragma NOIV, but
7386 less syntacticly kludgy). The interrupt number is also now
7387 range checked. Also fixed a bug in the high order bit example

7403 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7405 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7406 be re-activated by defining REDUCE_LITERALS)
7407 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7408 unsigned, but are signed by default
7409 * src/SDCCval.c (constVal): rearranged
7410 * src/SDCCval.c (valMod): preliminary fix
7411 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7863 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
7864 the regression tests I'm not brave enough to enable 245.b, 245.c
7865 * doc/sdccman.lyx: added latex preamble for hyperref package.
7866 Using pdflatex this will give you a hyperlinked pdf file with
7867 bookmarks. (prepend '%' before /usepackage if this breaks something)

7883 Applied patch from bug 737905 (renamed yylineo to mylineno):
7890 * src/pic16/pcode.c: Cleaned warnings
7891 * src/pic16/pcodeflow.c: Cleaned warnings
7892 * src/pic16/pcoderegs.c: Cleaned warnings

7903 * src/pic16/pcode.c (pic16_get_op): fixed warning on alpha
7905 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
7907 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
7908 it can be defined with CFLAGS when running configure
7909 * src/SDCCmain.c: fixed compiling + linking with object files
7911 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
7913 * configure.in: configure for pic16 port,
7914 added --disable-pic16-port
7915 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7916 * src/SDCCmain.c: linkOptions is changed to set *,
7917 added if/endif conditional macros to remove options help
7918 messages from optionsTable when a port is not configured, added
7919 support for the PIc16 port in the ports table, when executing
7920 the compiler with no port specified on command line, a default
7921 port is selected with the new macro DEFAULT_PORT which is
7922 defined in port.h, in setDefaultOptions() linkOptions is removed
7923 from initialization assignment, since now it is a set,
7924 parseCmdLine uses setParseWithComma for linkOptions, in
7925 linkEdit() linkOptions are accessed with new function indexSet()
7926 which returns the i'th item of a set variable. See SDCCset.c, in
7927 linkEdit() when calling buildCmdLine(), added linkOptions as
7928 last argument. Now users can pass arguments to gplink via the
7929 -Wl option, main() uses pic16glue() to glue up pic16 programs
7930 * src/SDCCpeeph.c: various changes to support pic16
7931 * src/SDCCset.c: added function void *indexSet(set *, int) to
7932 return the i'th item of the set

7937 added macro DEFAULT_PORT
7938 * src/pic/main.c: corrected arguments of gplnk in _linkCmd
7939 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
7941 * src/pic16/glue.c: commented out some error producing lines
7942 * src/pic16/main.c: __config directives are commented out to stop
7943 gpasm complaining and test the linkage with gplink, _linkCmd and
7944 _asmCmd changed to be more gplink and gpasm friendly
7945 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7946 produced an error when parsed, peep rule 12 is added to utilize
7947 movff, but it is commented out since the pCode does not support
7948 yet a command with 2 address arguments
7950 2003-05-18 <johan AT balder>
7952 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
7953 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7977 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
7979 2003-05-11 Borut Razem <borut.razem AT siol.net>
7981 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7982 the path of bin directory, so that PATH is the only env. variable, which has to be set
7983 in case of standard installation.
7984 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

9016 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9017 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9018 following files to include the previous two files: aslink.dsp,
9019 Makefile.aslink, Makefile.bcc, and Makefile.in.
9021 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9022 .adb instead of .cdb
9024 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9026 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9027 value from option --iram-size.
9029 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9031 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9034 2002-09-18 <wiml AT hhhh.org>
9036 * SDCClrange.h: exposed setFromRange() and setToRange()
9037 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9038 packRegsForAccUse() (bug 542397)
9039 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9040 multiple times and emitting the fetch operations more than once
9041 added aopGetUsesAcc() function to allow binary operators to
9042 fetch their operands in the correct order; made genMinus() emit
9043 compact code for X = LITERAL - Y
9045 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9046 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9047 sprintf() in line 1267.
9049 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

9053 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9054 Changes to aslink (All the changes are marked with 'JCF'):
9056 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9059 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9060 area BSEG. Also moves, if possible, the DATA area down into the internal
9061 ram so more space is available.
9063 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9066 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9067 not bytes. Function summary() which creates a memory usage summary
9068 file with extension .mem. Reports of overlaping stack and small stack
9069 size. If the space for the stack is less than 16 bytes aslink trows a
9072 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9073 the 8051. Option 'y' for memory summary output file.
9075 Changes to sdcc (All the changes are marked with 'JCF'):
9077 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9079 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9080 overlaying area for it (uses RegBankUsed[4]).
9082 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9083 bank zero as used by default. By default aslink locates the stack
9084 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9085 the creation of the .mem file. Delegates the allocation of data area
9086 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9087 the begining of the stack area to aslink.
9089 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9090 glue() in SDCCglue.c creates an area for it.
9092 2002-09-03 Borut Razem <borut.razem AT siol.net>
9093 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,

9096 errors, assertions, ...
9098 2002-08-29 Borut Razem <borut.razem AT siol.net>
9099 * sdcc/support/cpp2/auto-host_vc_in.h:
9100 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9101 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9102 Maybe there is a similar problem with BORLANDC? It should be checked!
9104 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9105 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9106 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9107 was not executed, and the compiler (cl) launched a warning:
9108 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9110 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9111 * src/SDCCglue.c (printIvalArray): iterative calculation of array length

9116 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9117 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9118 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9119 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9120 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9121 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9122 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9123 - added Release configuration in VS projects
9124 - review of compiler an linker options
9125 - VC .exe files are generated in bin_vc directory, not to interfere
9126 with binaries generated from other projects (cygwin, mingw, bcc ...)
9128 * sdcc/src/yacc.dsp: added
9130 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9131 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9132 and insert the version number definitions from .version
9134 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9136 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

9145 2002-08-11 Borut Razem <borut.razem AT siol.net>
9146 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9148 2002-08-10 Borut Razem <borut.razem AT siol.net>
9149 * src/SDCCmain.c (main):
9150 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9151 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9152 The consequence was that some temporary files were not removed.
9155 unification of code in functions tempfilename() and tempfile():
9156 function tempnam() is defined in Visual Studio 6.0 and .NET
9158 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9160 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9161 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9162 - removed compiler command line option /WX: Treats all warnings as errors
9163 - update a list of source files, included into the project
9165 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9166 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9167 changed project type to Generic Project so that can be correcly converted to VS.NET project
9169 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9171 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9173 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9175 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9176 added return 0 statements after assert() to make compiler happy
9178 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9179 added newline in the def file to keep MSC compiler satisfied
9181 * sdcc/src/z80/gen.c:
9182 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9183 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9184 - solved MSC error in function aopDump()
9186 * sdcc_vc.h: define PREFIX as "\\sdcc"
9188 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9189 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

9237 Added -p option. Allows port dependent processor to be specified.
9240 Initialized the new field char *Processor field to NULL in all ports
9243 Compiler generated registers for interrupt context saving
9244 were not getting allocated.
9246 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9249 Fixed left shift. Will promote the left side of a left shift
9250 if a) left shifting more than size of operand or b) when assigned
9251 to something size > size of left side
9253 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9255 tons of changes. Register allocation has been
9256 rewritten. Added customization for the various PICs. Flow

9361 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
9363 * sdcc/src/SDCCloop.c:
9364 Previous fix was not good. basic blocks that have "break" or "return" are
9365 not really partof a loop , but live ranges used in these blocks should
9366 be live thru the entire loop, so set partOfLoop but don't add them to
9369 2002-02-21 <johan AT FRIJA>
9371 * src/SDCCcse.c: fixed bug #514308
9373 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

9377 statement inside a loop, it was not being considered part of the loop.
9379 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
9381 2002-02-10 Karl Bongers <karl AT turbobit.com>
9384 Fixed up SDCDB debugger somewhat. Updated debugger/README
9385 with lots of comments and notes.
9387 * device/examples/test2.c:
9388 Fix bug, "red" variable not being initialized(compiler complained).

9392 for use as a multiple module SDCDB test case.
9394 * sim/ucsim/cmd.src/cmdset.cc:
9395 Took out debug printfs in ucsim "next" command.
9398 Karl and Johan start ucsim XA support. Most dissassembly working,
9399 about 75% emulation done(plenty of work remaining).
9401 * sim/ucsim/z80.src:
9402 Add Z80 support to ucsim, add test-ucz80 regression test,
9403 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
