1943 * device/lib/printf_large.c: removed inline assembly for portability and
1944 readability. Use printf_fast if speed or size are more important.
1945 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1946 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1948 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1950 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1951 prevent compiler warning
1953 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1955 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1956 moved to level 0 and declared as static. Also they are explicit
1957 placed in access bank. This was necessery because some times they
1958 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1959 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1960 optimizations. Currently only compare to unsigned char is implemented,
1961 * src/pic16/gen.c: added fReturnIdx array,
1962 * (struct resolvedIfx) is moved to gen.h and made public,
1963 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1964 * (aopForSym): added an optimization to directly store in stack of
1965 the operand of a SEND iCode,
1966 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1967 but as registers instead (AOP_REG) using the fReturnIdx array,
1968 * (pic16_freeAsmop): remove the freed register from the
1969 _G.sregsAlloc field,
1970 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1971 a compare of 'WREG',
1972 * (pic16_popGetTempRegCond): changed function prototype, now
1973 function takes also a bitVector argument v which holds the current
1974 set of registers that are allocated for stack access by aopForSym,
1975 registers allocated in aopForSym for accessing stack symbols are not
1976 any more part of the functions usedRegs field,
1977 * (genCall): some times aopOp is called for a stack variable to be
1978 send, aopForSym might perform the push, if this is true make sure
1979 that genCall doesn't push the variable twice by testing _G.resDirect,
1980 * (genFunction): changed testing for unspecified interrupt number
1981 from 256 to INTNO_UNSPEC,
1982 * modified selection scheme of frame pointer generation. Previously
1983 if function did use local registers a frame pointer was generated,
1984 now a frame pointer is generated only if function has arguments
1985 (that need PLUSW2 register access), or has stack arguments, or the
1986 compiler is not instructed to omit the frame pointer,
1987 * (genEndFunction): before restoring local registers that were saved
1988 in the function preamble, also restore the registers that *might*
1989 have been allocated for stack access,
1990 * (genRet): removed some old comments,
1991 * (genCmp, the active (RN's) version): added a call to the
1992 pic16_genCmp_special function to perform the compare with a more
1993 robust and optimized way,
1994 * (genInline): a feature has been added in inline code generation,
1995 which allows a wildcard variable substitution when writing inline
1996 assembly. Code is incomplete and experimental therefore undocumented,
1997 * (genCast): changed order of aopOp for result and right to allow
1998 aopForSym to directly load the result if possible,
1999 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2000 perform an optimized compare on some selected special occasions,
2001 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2002 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2003 generate an IVT any more,
2004 * src/pic16/main.c (pic16_optionsTable): added command line option
2006 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2007 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2009 * src/pic16/NOTES: Raphael Neider added in list of active developers
2010 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2011 jumptable_end to prevent bug #,
2012 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2013 inCond and outCond fields,
2014 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2015 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2016 turn off register spilling,
2017 * (packRegsForOneUse): synced with other ports' versions although it
2018 is not used currently,
2019 * (pic16_packRegisters): added an optimization while reading
2020 structure bitfields, some registers may be saved (malloc code is
2021 decreased by 80 bytes)
2023 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2025 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2026 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2027 this can be optimized more?
2029 2005-03-10 Raphael Neider <rneider AT web.de>
2031 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2032 genNearPointerGet): (hopefully) fixed access to bitfields via
2033 pointers (p->bitN = x; and x = p->bitN; failed)
2035 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

2667 Adding support for replacing ljmps with sjmps in jumptables
2668 generated for switch statements. For now you need to set the
2669 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2670 Now 4 algorithms for mcs51 jumptable generation are used:
2671 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2672 addresses loaded pc-relative for up to 112 cases and stack-pushing
2673 target addresses loaded with offset from dptr for up to 256 cases.

2700 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
2701 to call when a stack overflow occurs,
2702 * (malloc.h): added CVS Id tag,
2703 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2705 * added libc directory. The current version of LibC contains string
2706 functions, ctype functions and macros and some functions of the
2707 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2708 be extensively tested in the future. Standard disclaimer here.
2709 Library is not automatically build yet. But one can build it by
2710 invoking 'make' inside the libc directory.
2711 * added ADC library under libio. Preliminary version yet.

2720 * (genUminusFloat): fixed for pic16, ported code from mcs51,
2721 * (pic16_storeForReturn): optimized return of 0,
2722 * (genCmp): experimental code for new genCmp which uses PIC18's
2723 special compare&skip instructions. Initial tests fail some times
2724 with variables grater than 1 byte in size, so new code is disabled,
2725 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2727 * (genCast): began a fix to optimize the casting of a bit to another
2728 bit, now assigning a bitfield to another bitfield will fail, sorry,
2729 * src/pic16/main.c: disabled the use of lr-support feature,
2730 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

2733 bits with offset (case PO_GPR_BIT),
2734 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
2736 * (isBankInstruction): modified to return 0 for no banking instruction,
2737 and 1 for banking instruction,
2738 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2739 caused stop processing pCodes after a inline assembly block,
2740 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
2741 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
2742 registers when it shouldn't,
2743 * src/pic16/ralloc.c (allocReg): add preliminary support for
2744 supporting a limited set of temporary registers,
2746 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2748 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
2749 genDataPointerSet): ensure assignments always copy in MSB to LSB
2751 (loadRegFromAop): recognize CLRH optimization,
2752 (genFunction): optimize RECEIVE iCodes in reentrant functions
2754 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2756 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

5683 * src/pic/glue (pic14emitRegularMap),
5684 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
5686 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>
5688 * src/pic/pcode.c (PCodeID): commented out left over debug code
5690 2004-01-20 Bernhard Held <bernhard AT bernhardheld.de>
5692 * support/valdiag/tests/overflow.c: added shift tests
5700 * src/pic/pcodepeep.c,
5701 * src/pic/pcoderegs.c,
5703 * src/pic/ralloc.h: applied patch from Slade Rich;
5704 added support for multiple code pages and multiple RAM banks on the
5705 PIC 14 port. The ASM files now no longer simply assume all the
5706 code / RAM are in the same page / bank. This means the linker can
5707 safely allocate code/RAM of separate ASM files to different pages/banks.
5708 * doc/sdccman.lyx: added Slade's tips
5709 * src/mcs51/peeph.def: fixed bug #880768

5718 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
5721 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
5722 strtof is not part of C89 and isn't included with Mac OS X.
5724 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5726 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

5751 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5753 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5754 loaded with the linker search paths (-L arguments) and the libraries
5755 to be linked with the current source (-l arguments). Changes
5756 currently will affect only the pic16 port.
5757 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5758 include path the port specific paths and port specific libraries,
5759 * gplink command now contains the $3 argument,
5760 * src/pic16/device.h,
5761 * src/pic16/device.c,: structure PIC_device is made public and
5762 renamed to PIC16_device, the same for variable Pics which is renamed
5763 to Pics16. Updated all references to them.
5764 * src/pic16/glue.c (pic16glue): corrected bug with code
5765 initialization which bypassed the variable initializations block.
5767 * device/lib/pic16/Makefile.rules: removed --penable-stack from
5768 COMPILE_FLAGS and added the --nostdinc option
5770 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5777 Documenting changes from previous commits.
5778 * configure.in (version 1.56),
5779 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5780 when generating output files to configure the pic16 library,
5781 but now I've commented it out, since gputils aren't installed in the
5782 SF compile farm, so library won't compile
5784 * device/lib/Makefile.in (version 1.56): initially I've added in
5785 target 'all' the prerequestive 'model-pic16' so it compiled the
5786 pic16 library, but now I've commented it out for the same reasons
5788 * added targets 'model-pic16' and 'objects-pic16' to compile the
5790 * added target 'port-specific-objects-pic16' to handle the
5791 generated libraries and copy them into the build/ directory
5792 * added target 'clean-intermediate-pic16' to clean intermediate
5793 files into pic16 directory
5794 * in target 'installdirs' added line to create directory pic16 in
5795 the installation path
5797 * device/include/Makefile.in (version 1.11): in target 'install'
5798 added lines to copy all header files to installation path,
5799 * in target 'installdirs' added line create directory for pic16
5800 headers in the installation path

5815 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5816 option so that it actually works. Made it specific to the z80, since
5817 the gbz80 doesn't have these kinds of I/O ports.
5819 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5821 * device/include/z180.h,

5843 Mainly changes to support compilation of the device libraries
5844 * src/pic16/device.c: stack is allocated via symbol and not
5845 via literal number. The symbol is placed in the corresponding
5846 position of the data ram
5847 * (pic16_dump_section): relocatable and absolute uninitialized
5848 data are now emitted in sorted order to reduce section naming,
5849 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5850 weren't marked as being in the access bank,
5852 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5854 Added portion of GNU PIC Library under the directory
5855 device/include/pic16 and device/lib/pic16. These files
5856 contain the declarations of SFRs for the PIC18Fxx2 devices.
5857 The directory is initialized via configure from toplevel.
5859 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
5861 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

5887 all over. Telling LaTeX to be less strict with word spacing
5888 to better keep the right margin. Changed some notes about
5889 maintainance of the ports in section 3.2.1 - is it OK like this?
5891 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5929 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5931 * src/pic16/peeph.def: all peepholes with movff are commented out,
5932 because there is a problem in the pcode peep optimizer,
5933 * src/pic16/ralloc.c: the register allocator can now reuse local

6085 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6087 PIC16 port related changes:
6088 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6089 added variable stackPos,
6091 * gen.c: genCall, assignResultValue: added support for
6092 pushing/retrieving function parameters to/from stack,
6093 genFunction,genEndFunction: setup stack frame for the
6095 genAddrOf: will be changed according to bug 863624
6097 * added files genutils.c and genutils.h which contain gen*
6098 debugged and optimised functions extracted from gen.c
6100 * glue.c: added variable 'externs' which holds extern symbols,
6101 pic16emitRegularMap: is modified to properly handle relocatable
6102 symbols under the new scheme,
6103 pic16createInterruptVect: is modified
6104 pic16printPublics: is modified to emit 'global' assembler directives,
6105 added pic16_printExterns to print extern symbols,
6106 pic16glue: initializes stack/frame pointer in the beginning of
6107 the assembly output. Temporary hack, will be corrected later,
6108 because gplink yet does not support stack and SDCC does not
6109 yet support a type of crt0.o object to create the final binary.
6111 * Removed many lines that contain 8051 legacy code.
6112 * The code is finally placed under a 'code' directive.
6113 * Added port specific options.
6115 * _process_pragma: simplified since now we do not need *special*
6116 include file to define SFR registers. But a separate header
6117 will be needed. This will be developed later.
6118 * _pic16_parseOptions: added, parses port specific options:
6119 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6120 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6121 --preplace-udata-with=
6123 * _pic16_setDefaultOptions: modified to initialize section names,
6124 but hack is temporarly out of order since it needs improvement.
6125 * _pic16_genAssemblerPreamble: configuration words are emitted by
6126 their address instead of their name. This part is incomplete and
6127 supports only the 18Fxx2 devices. Other devices will emit an error
6128 during assembly since they do not contain the same set of config
6130 * _pic16_genIVT: is modified,
6132 * pcode.c: added definitions for some hardware registers that are needed
6134 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6135 All PCI entries are updated. Now LFSR is supported.
6136 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6137 * added pic16_newpCodeOpLit2 to support instructions with
6138 two literal arguments
6139 * pic16_pCode2str: corrected code that emits assembler instructions
6140 with two literal operands and those that have an access bit modifier
6141 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6142 this fixes a bug which caused some labels to be lost, when an
6143 assembler directive was added, i.e. banksel,
6144 * pic16_FixRegisterBanking: improved logic that causes the insertion
6146 * InlineFunction: functions that are called once, are not any more
6147 inlined. This can be a port option in the future,
6149 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6151 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6152 hold the corresponding uninitialized symbols,
6153 * pic16_allocProcessorRegister: registers have explicit marked the
6155 * pic16_allocInternalRegister: registers are explicit marked as
6157 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6158 processing list, so bit registers were lost,
6161 * ralloc.h: added field 'accessBank' and original symbol operand
6162 in register definition,
6163 * removed the field isMapped from register definition,
6165 ** Several functions have been removed from various sources:
6166 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6167 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6168 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6169 pic16_assignRelocatableRegisters
6171 ** others have been introduced:
6172 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6173 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6175 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6177 * support/scripts/inc2h.pl: changed definition of BIT_AT
6178 to emit 'sbit at' instead of 'bit at'. This was a request.
6180 PIC16 port related preliminary changes:
6181 * gen.c: prefixed function popRegFromString with
6182 pic16_ and all references to it corrected
6183 * pcode.c: all pic16_pc_* hardware registers prefixed
6184 with underscore (_),
6185 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6186 * ralloc.c: newReg(): when register is REG_SFR then
6187 set address to rIdx,
6188 pic16_allocProcessorRegister(): marks register wasUsed=0
6189 pic16_writeUsedRegs(): added a call to assign processor
6190 registers via pic16_assignFixedRegisters
6192 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6194 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6195 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6196 variables in unused register banks. Also the SSEG is placed
6197 wherever there is enough space for it, and IDATA can be anywhere
6198 in internal RAM. For now compile using -Wl-Y[stack_size].
6199 The mem file is different for this option as well, since it
6200 makes no sense of talking about DSEG lenght.
6202 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6204 * src/SDCClrange.c: fixed bug 869095 that caused segfault

6449 * src/SDCCast.c (decorateType): disabled a transformation I added in
6450 revision 1.188 (access to fields of a structure at an absolute address);
6451 it breaks with bitfields, extern declarations, and gcse analysis.
6452 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
6453 could be assigned through a pointer, so don't complain.

7177 reported in bug #800609
7179 2003-09-04 Vangelis Rokas <vrokas AT otenet.gr>
7181 * Top header beautifications in src/pic16 directory:
7182 device.c, device.h, gen.c, gen.h, genarith.c, glue.c, pcode.c,
7183 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
7184 pcoderegs.h, ralloc.c, ralloc.h
7185 * main.c: added top header and GPL license notice
7186 * pcode.c: fixed the if-conditional warning
7188 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
7190 * device/lib/_mullong.c: replaced int by short for gcc
7192 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7194 * src/SDCCpeeph.c (notVolatile, notVolatileVariable): handle IFX
7195 and JUMPTABLE iCodes properly now (worked by accident before)
7196 * src/mcs51/gen.c (leftRightUseAcc),
7197 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
7198 iCode properly now. Use getSize instead of nRegs since a & b
7199 aren't part of the nRegs tally.
7201 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
7203 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()
7204 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
7205 before instructions that use the _STATUS register
7207 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
7209 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
7210 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7211 fetching of the pointer
7212 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7213 copied from genNearPointerSet()
7214 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7215 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
7216 If they pop r0/r1 they must be called in the opposite order than aopOp().
7217 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
7218 (resp. --stack-auto), prepared for --xstack
7220 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

7224 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7226 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
7227 these ports have their own __sdcc_external_start()
7229 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7231 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7232 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7233 type for bits was changed. It resulted in bit variables becoming
7234 global, which is not permitted in PIC 14 assembly output.
7236 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7238 * doc/sdccman.lyx: various additions and updates. Rearranged sections
7240 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7242 Z80 and MCS51 linkers complaint if a public symbol is defined
7243 in more than one library module:
7247 * as/mcs51/Makefile.in
7249 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7251 A few small changes that speed up the peephole optimizer.
7255 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7257 Try to make the peephole optimizer smarter by maintaining
7258 an association between the assembly source code and the
7259 iCodes that originated them. Put this information to use
7260 with a new peephole rule condition "notVolatile" so that
7261 the rules can be aggressive yet still safe.
7266 * src/mcs51/peeph.def
7268 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7272 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7273 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7274 if the left or right operand symbols have the accuse flag set.
7276 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7278 Changed the type of the result of the ! (NOT) operator to char;
7279 previously it returned the same type as the source. This allows
7280 us to eliminate all the genFloatNot functions (all of its target
7281 implementations were very buggy) since !float can use the same
7284 * src/SDCCicode.c (ast2iCode): ! returns char
7285 * src/mcs51/gen.c (genNot, genNotFloat),
7286 * src/ds390/gen.c (genNot, genNotFloat),
7287 * src/z80/gen.c (genNot, genNotFloat),
7288 * src/pic/gen.c (genNot, genNotFloat),
7289 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
7291 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
7293 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7294 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7295 during interrupts. Ensure WSAVE is located at a shared bank address.
7296 2. Fixed page selection in some places
7297 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7298 the registers name strings.
7299 4. Fixed "signed / unsigned compare" compiler warnings.
7300 5. The PIC port manages its own allocation of the general purpose
7301 registers, but makes no attempt to reuse them. As a result when
7302 compiling it soon runs out of general purpose registers. Some
7303 additional code was added to the files pcode.c and device.c to walk
7304 through the function call tree and rename the registers so that they
7314 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7315 genPlus() & genMinus() when the result is the same as left or right
7317 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7321 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7323 Made bitfield a distinct type from bit so that bitfields
7324 convert as per ANSI C and bits retain their traditional
7325 boolean style behaviour. Implemented bitfield support in
7333 * src/ds390/gen.c: bit v bitfield split
7334 * src/z80/gen.c: New support for bitfields
7335 * support/regression/tests/bitfields.c: reenabled z80,
7338 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7340 Rules 246.x, 247.x relate to bitfields, the others speed up
7341 access to xdata mapped I/O devices.
7343 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7345 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7347 Cleaned up genPackBits and genUnpackBits and added two helper
7348 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7349 for literal assignments in genPackBits (thanks to Frieder for
7355 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7357 Fixed bug #748310 (pointer to function type mishandled when the
7358 function name is omitted). Also fixed a SIGSEGV when a function
7359 attribute (reentrant, etc) is used on a non-function or on a
7360 function but misplaced before the parameter list.
7362 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7364 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7365 * support/Util/SDCCerr.h,
7366 * support/Util/SDCCerr.c: Added func attr misuse error msg
7368 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
7370 Fixed bug #787649 by anonymous
7371 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
7372 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
7374 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7387 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7389 Made the constant following the "interrupt" keyword optional. If
7390 omitted, the function will not automatically be given an entry
7391 in the interrupt vector table (similar to #pragma NOIV, but
7392 less syntacticly kludgy). The interrupt number is also now
7393 range checked. Also fixed a bug in the high order bit example
7400 * support/Util/SDCCerr.c
7401 * support/Util/SDCCerr.h
7404 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

7407 * src/SDCCicode.c (operandOperation): rewritten some ops
7408 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7409 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7411 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7412 be re-activated by defining REDUCE_LITERALS)
7413 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7414 unsigned, but are signed by default
7415 * src/SDCCval.c (constVal): rearranged
7416 * src/SDCCval.c (valMod): preliminary fix
7417 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7460 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
7461 * src/SDCCval.c (valDiv, valMod): fixed signdness
7462 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
7463 signedness of modulo, left and right shift

7869 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
7870 the regression tests I'm not brave enough to enable 245.b, 245.c
7871 * doc/sdccman.lyx: added latex preamble for hyperref package.
7872 Using pdflatex this will give you a hyperlinked pdf file with
7873 bookmarks. (prepend '%' before /usepackage if this breaks something)

7911 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
7913 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
7914 it can be defined with CFLAGS when running configure
7915 * src/SDCCmain.c: fixed compiling + linking with object files
7917 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

7920 added --disable-pic16-port
7921 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7922 * src/SDCCmain.c: linkOptions is changed to set *,
7923 added if/endif conditional macros to remove options help
7924 messages from optionsTable when a port is not configured, added
7925 support for the PIc16 port in the ports table, when executing
7926 the compiler with no port specified on command line, a default
7927 port is selected with the new macro DEFAULT_PORT which is
7928 defined in port.h, in setDefaultOptions() linkOptions is removed
7929 from initialization assignment, since now it is a set,
7930 parseCmdLine uses setParseWithComma for linkOptions, in
7931 linkEdit() linkOptions are accessed with new function indexSet()
7932 which returns the i'th item of a set variable. See SDCCset.c, in
7933 linkEdit() when calling buildCmdLine(), added linkOptions as
7934 last argument. Now users can pass arguments to gplink via the
7935 -Wl option, main() uses pic16glue() to glue up pic16 programs

7947 * src/pic16/glue.c: commented out some error producing lines
7948 * src/pic16/main.c: __config directives are commented out to stop
7949 gpasm complaining and test the linkage with gplink, _linkCmd and
7950 _asmCmd changed to be more gplink and gpasm friendly
7951 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7952 produced an error when parsed, peep rule 12 is added to utilize
7953 movff, but it is commented out since the pCode does not support
7954 yet a command with 2 address arguments
7956 2003-05-18 <johan AT balder>
7958 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
7959 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7983 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
7985 2003-05-11 Borut Razem <borut.razem AT siol.net>
7987 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7988 the path of bin directory, so that PATH is the only env. variable, which has to be set
7989 in case of standard installation.
7990 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

9022 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9023 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9024 following files to include the previous two files: aslink.dsp,
9025 Makefile.aslink, Makefile.bcc, and Makefile.in.
9027 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9028 .adb instead of .cdb
9030 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9032 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9033 value from option --iram-size.
9035 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9037 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9040 2002-09-18 <wiml AT hhhh.org>
9042 * SDCClrange.h: exposed setFromRange() and setToRange()
9043 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9044 packRegsForAccUse() (bug 542397)
9045 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9046 multiple times and emitting the fetch operations more than once
9047 added aopGetUsesAcc() function to allow binary operators to
9048 fetch their operands in the correct order; made genMinus() emit
9049 compact code for X = LITERAL - Y
9051 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9052 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to

9059 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9060 Changes to aslink (All the changes are marked with 'JCF'):
9062 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9065 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9066 area BSEG. Also moves, if possible, the DATA area down into the internal
9067 ram so more space is available.
9069 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9072 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9073 not bytes. Function summary() which creates a memory usage summary
9074 file with extension .mem. Reports of overlaping stack and small stack
9075 size. If the space for the stack is less than 16 bytes aslink trows a
9078 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9079 the 8051. Option 'y' for memory summary output file.
9081 Changes to sdcc (All the changes are marked with 'JCF'):
9083 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9085 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9086 overlaying area for it (uses RegBankUsed[4]).
9088 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9089 bank zero as used by default. By default aslink locates the stack
9090 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9091 the creation of the .mem file. Delegates the allocation of data area
9092 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9093 the begining of the stack area to aslink.
9095 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9096 glue() in SDCCglue.c creates an area for it.

9099 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9100 sdcc/src/pic/glue.c:
9101 introduced atexit() handler for teporay files removal in case of
9102 errors, assertions, ...
9104 2002-08-29 Borut Razem <borut.razem AT siol.net>
9105 * sdcc/support/cpp2/auto-host_vc_in.h:
9106 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9107 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9108 Maybe there is a similar problem with BORLANDC? It should be checked!
9110 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9111 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9112 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9113 was not executed, and the compiler (cl) launched a warning:
9114 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9116 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9117 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9119 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9120 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9122 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9123 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9124 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9125 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9126 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9127 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9128 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9129 - added Release configuration in VS projects
9130 - review of compiler an linker options
9131 - VC .exe files are generated in bin_vc directory, not to interfere
9132 with binaries generated from other projects (cygwin, mingw, bcc ...)
9134 * sdcc/src/yacc.dsp: added
9136 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9137 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9138 and insert the version number definitions from .version
9140 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9142 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9143 added - genarate auto-host.h using auto-host_vc_in.h as template
9146 removed from CVS, generated automatically
9148 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9149 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9151 2002-08-11 Borut Razem <borut.razem AT siol.net>
9152 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9154 2002-08-10 Borut Razem <borut.razem AT siol.net>
9155 * src/SDCCmain.c (main):
9156 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9157 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9158 The consequence was that some temporary files were not removed.
9161 unification of code in functions tempfilename() and tempfile():
9162 function tempnam() is defined in Visual Studio 6.0 and .NET
9164 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9166 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9167 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9168 - removed compiler command line option /WX: Treats all warnings as errors
9169 - update a list of source files, included into the project
9171 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9172 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9173 changed project type to Generic Project so that can be correcly converted to VS.NET project
9175 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9177 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9179 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9181 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9182 added return 0 statements after assert() to make compiler happy
9184 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9185 added newline in the def file to keep MSC compiler satisfied
9187 * sdcc/src/z80/gen.c:
9188 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9189 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9190 - solved MSC error in function aopDump()
9192 * sdcc_vc.h: define PREFIX as "\\sdcc"
9194 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9195 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

9243 Added -p option. Allows port dependent processor to be specified.
9246 Initialized the new field char *Processor field to NULL in all ports
9249 Compiler generated registers for interrupt context saving
9250 were not getting allocated.
9252 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9255 Fixed left shift. Will promote the left side of a left shift
9256 if a) left shifting more than size of operand or b) when assigned
9257 to something size > size of left side
9259 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9261 tons of changes. Register allocation has been
9262 rewritten. Added customization for the various PICs. Flow

9367 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
9369 * sdcc/src/SDCCloop.c:
9370 Previous fix was not good. basic blocks that have "break" or "return" are
9371 not really partof a loop , but live ranges used in these blocks should
9372 be live thru the entire loop, so set partOfLoop but don't add them to
9375 2002-02-21 <johan AT FRIJA>
9377 * src/SDCCcse.c: fixed bug #514308
9379 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

9385 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
9387 2002-02-10 Karl Bongers <karl AT turbobit.com>
