1945 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1947 * device/lib/printf_large.c: removed inline assembly for portability and
1948 readability. Use printf_fast if speed or size are more important.
1949 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1950 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1952 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1954 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1955 prevent compiler warning
1957 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1959 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1960 moved to level 0 and declared as static. Also they are explicit
1961 placed in access bank. This was necessery because some times they
1962 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1963 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1964 optimizations. Currently only compare to unsigned char is implemented,
1965 * src/pic16/gen.c: added fReturnIdx array,
1966 * (struct resolvedIfx) is moved to gen.h and made public,
1967 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1968 * (aopForSym): added an optimization to directly store in stack of
1969 the operand of a SEND iCode,
1970 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1971 but as registers instead (AOP_REG) using the fReturnIdx array,
1972 * (pic16_freeAsmop): remove the freed register from the
1973 _G.sregsAlloc field,
1974 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1975 a compare of 'WREG',
1976 * (pic16_popGetTempRegCond): changed function prototype, now
1977 function takes also a bitVector argument v which holds the current
1978 set of registers that are allocated for stack access by aopForSym,
1979 registers allocated in aopForSym for accessing stack symbols are not
1980 any more part of the functions usedRegs field,
1981 * (genCall): some times aopOp is called for a stack variable to be
1982 send, aopForSym might perform the push, if this is true make sure
1983 that genCall doesn't push the variable twice by testing _G.resDirect,
1984 * (genFunction): changed testing for unspecified interrupt number
1985 from 256 to INTNO_UNSPEC,
1986 * modified selection scheme of frame pointer generation. Previously
1987 if function did use local registers a frame pointer was generated,
1988 now a frame pointer is generated only if function has arguments
1989 (that need PLUSW2 register access), or has stack arguments, or the
1990 compiler is not instructed to omit the frame pointer,
1991 * (genEndFunction): before restoring local registers that were saved
1992 in the function preamble, also restore the registers that *might*
1993 have been allocated for stack access,
1994 * (genRet): removed some old comments,
1995 * (genCmp, the active (RN's) version): added a call to the
1996 pic16_genCmp_special function to perform the compare with a more
1997 robust and optimized way,
1998 * (genInline): a feature has been added in inline code generation,
1999 which allows a wildcard variable substitution when writing inline
2000 assembly. Code is incomplete and experimental therefore undocumented,
2001 * (genCast): changed order of aopOp for result and right to allow
2002 aopForSym to directly load the result if possible,
2003 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2004 perform an optimized compare on some selected special occasions,
2005 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2006 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2007 generate an IVT any more,
2008 * src/pic16/main.c (pic16_optionsTable): added command line option
2010 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2011 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2013 * src/pic16/NOTES: Raphael Neider added in list of active developers
2014 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2015 jumptable_end to prevent bug #,
2016 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2017 inCond and outCond fields,
2018 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2019 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2020 turn off register spilling,
2021 * (packRegsForOneUse): synced with other ports' versions although it
2022 is not used currently,
2023 * (pic16_packRegisters): added an optimization while reading
2024 structure bitfields, some registers may be saved (malloc code is
2025 decreased by 80 bytes)
2027 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2029 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2030 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2031 this can be optimized more?
2033 2005-03-10 Raphael Neider <rneider AT web.de>
2035 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2036 genNearPointerGet): (hopefully) fixed access to bitfields via
2037 pointers (p->bitN = x; and x = p->bitN; failed)

2671 Adding support for replacing ljmps with sjmps in jumptables
2672 generated for switch statements. For now you need to set the
2673 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2674 Now 4 algorithms for mcs51 jumptable generation are used:
2675 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2676 addresses loaded pc-relative for up to 112 cases and stack-pushing
2677 target addresses loaded with offset from dptr for up to 256 cases.
2679 * src/SDCCpeeph.c: added peephole conditional labelJTInRange

2704 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
2705 to call when a stack overflow occurs,
2706 * (malloc.h): added CVS Id tag,
2707 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2709 * added libc directory. The current version of LibC contains string
2710 functions, ctype functions and macros and some functions of the
2711 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2712 be extensively tested in the future. Standard disclaimer here.
2713 Library is not automatically build yet. But one can build it by
2714 invoking 'make' inside the libc directory.
2715 * added ADC library under libio. Preliminary version yet.

2724 * (genUminusFloat): fixed for pic16, ported code from mcs51,
2725 * (pic16_storeForReturn): optimized return of 0,
2726 * (genCmp): experimental code for new genCmp which uses PIC18's
2727 special compare&skip instructions. Initial tests fail some times
2728 with variables grater than 1 byte in size, so new code is disabled,
2729 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2731 * (genCast): began a fix to optimize the casting of a bit to another
2732 bit, now assigning a bitfield to another bitfield will fail, sorry,
2733 * src/pic16/main.c: disabled the use of lr-support feature,
2734 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

2737 bits with offset (case PO_GPR_BIT),
2738 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
2740 * (isBankInstruction): modified to return 0 for no banking instruction,
2741 and 1 for banking instruction,
2742 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2743 caused stop processing pCodes after a inline assembly block,
2744 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
2745 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
2746 registers when it shouldn't,
2747 * src/pic16/ralloc.c (allocReg): add preliminary support for
2748 supporting a limited set of temporary registers,
2750 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2752 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
2753 genDataPointerSet): ensure assignments always copy in MSB to LSB
2755 (loadRegFromAop): recognize CLRH optimization,
2756 (genFunction): optimize RECEIVE iCodes in reentrant functions
2758 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2760 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

5687 * src/pic/glue (pic14emitRegularMap),
5688 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
5690 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>
5692 * src/pic/pcode.c (PCodeID): commented out left over debug code
5694 2004-01-20 Bernhard Held <bernhard AT bernhardheld.de>
5696 * support/valdiag/tests/overflow.c: added shift tests
5704 * src/pic/pcodepeep.c,
5705 * src/pic/pcoderegs.c,
5707 * src/pic/ralloc.h: applied patch from Slade Rich;
5708 added support for multiple code pages and multiple RAM banks on the
5709 PIC 14 port. The ASM files now no longer simply assume all the
5710 code / RAM are in the same page / bank. This means the linker can
5711 safely allocate code/RAM of separate ASM files to different pages/banks.
5712 * doc/sdccman.lyx: added Slade's tips
5713 * src/mcs51/peeph.def: fixed bug #880768

5722 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
5725 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
5726 strtof is not part of C89 and isn't included with Mac OS X.
5728 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5730 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

5755 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5757 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5758 loaded with the linker search paths (-L arguments) and the libraries
5759 to be linked with the current source (-l arguments). Changes
5760 currently will affect only the pic16 port.
5761 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5762 include path the port specific paths and port specific libraries,
5763 * gplink command now contains the $3 argument,
5764 * src/pic16/device.h,
5765 * src/pic16/device.c,: structure PIC_device is made public and
5766 renamed to PIC16_device, the same for variable Pics which is renamed
5767 to Pics16. Updated all references to them.
5768 * src/pic16/glue.c (pic16glue): corrected bug with code
5769 initialization which bypassed the variable initializations block.
5771 * device/lib/pic16/Makefile.rules: removed --penable-stack from
5772 COMPILE_FLAGS and added the --nostdinc option
5774 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5781 Documenting changes from previous commits.
5782 * configure.in (version 1.56),
5783 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5784 when generating output files to configure the pic16 library,
5785 but now I've commented it out, since gputils aren't installed in the
5786 SF compile farm, so library won't compile
5788 * device/lib/Makefile.in (version 1.56): initially I've added in
5789 target 'all' the prerequestive 'model-pic16' so it compiled the
5790 pic16 library, but now I've commented it out for the same reasons
5792 * added targets 'model-pic16' and 'objects-pic16' to compile the
5794 * added target 'port-specific-objects-pic16' to handle the
5795 generated libraries and copy them into the build/ directory
5796 * added target 'clean-intermediate-pic16' to clean intermediate
5797 files into pic16 directory
5798 * in target 'installdirs' added line to create directory pic16 in
5799 the installation path

5802 added lines to copy all header files to installation path,
5803 * in target 'installdirs' added line create directory for pic16
5804 headers in the installation path

5819 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5820 option so that it actually works. Made it specific to the z80, since
5821 the gbz80 doesn't have these kinds of I/O ports.
5823 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5825 * device/include/z180.h,

5847 Mainly changes to support compilation of the device libraries
5848 * src/pic16/device.c: stack is allocated via symbol and not
5849 via literal number. The symbol is placed in the corresponding
5850 position of the data ram
5851 * (pic16_dump_section): relocatable and absolute uninitialized
5852 data are now emitted in sorted order to reduce section naming,
5853 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5854 weren't marked as being in the access bank,
5856 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5858 Added portion of GNU PIC Library under the directory
5859 device/include/pic16 and device/lib/pic16. These files
5860 contain the declarations of SFRs for the PIC18Fxx2 devices.
5861 The directory is initialized via configure from toplevel.
5863 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
5865 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

5891 all over. Telling LaTeX to be less strict with word spacing
5892 to better keep the right margin. Changed some notes about
5893 maintainance of the ports in section 3.2.1 - is it OK like this?
5895 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5933 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5935 * src/pic16/peeph.def: all peepholes with movff are commented out,
5936 because there is a problem in the pcode peep optimizer,
5937 * src/pic16/ralloc.c: the register allocator can now reuse local

6089 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6091 PIC16 port related changes:
6092 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6093 added variable stackPos,
6095 * gen.c: genCall, assignResultValue: added support for
6096 pushing/retrieving function parameters to/from stack,
6097 genFunction,genEndFunction: setup stack frame for the
6099 genAddrOf: will be changed according to bug 863624
6101 * added files genutils.c and genutils.h which contain gen*
6102 debugged and optimised functions extracted from gen.c
6104 * glue.c: added variable 'externs' which holds extern symbols,
6105 pic16emitRegularMap: is modified to properly handle relocatable
6106 symbols under the new scheme,
6107 pic16createInterruptVect: is modified
6108 pic16printPublics: is modified to emit 'global' assembler directives,
6109 added pic16_printExterns to print extern symbols,
6110 pic16glue: initializes stack/frame pointer in the beginning of
6111 the assembly output. Temporary hack, will be corrected later,
6112 because gplink yet does not support stack and SDCC does not
6113 yet support a type of crt0.o object to create the final binary.
6115 * Removed many lines that contain 8051 legacy code.
6116 * The code is finally placed under a 'code' directive.
6117 * Added port specific options.
6119 * _process_pragma: simplified since now we do not need *special*
6120 include file to define SFR registers. But a separate header
6121 will be needed. This will be developed later.
6122 * _pic16_parseOptions: added, parses port specific options:
6123 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6124 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6125 --preplace-udata-with=
6127 * _pic16_setDefaultOptions: modified to initialize section names,
6128 but hack is temporarly out of order since it needs improvement.
6129 * _pic16_genAssemblerPreamble: configuration words are emitted by
6130 their address instead of their name. This part is incomplete and
6131 supports only the 18Fxx2 devices. Other devices will emit an error
6132 during assembly since they do not contain the same set of config
6134 * _pic16_genIVT: is modified,
6136 * pcode.c: added definitions for some hardware registers that are needed
6138 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6139 All PCI entries are updated. Now LFSR is supported.
6140 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6141 * added pic16_newpCodeOpLit2 to support instructions with
6142 two literal arguments
6143 * pic16_pCode2str: corrected code that emits assembler instructions
6144 with two literal operands and those that have an access bit modifier
6145 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6146 this fixes a bug which caused some labels to be lost, when an
6147 assembler directive was added, i.e. banksel,
6148 * pic16_FixRegisterBanking: improved logic that causes the insertion
6150 * InlineFunction: functions that are called once, are not any more
6151 inlined. This can be a port option in the future,
6153 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6155 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6156 hold the corresponding uninitialized symbols,
6157 * pic16_allocProcessorRegister: registers have explicit marked the
6159 * pic16_allocInternalRegister: registers are explicit marked as
6161 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6162 processing list, so bit registers were lost,
6165 * ralloc.h: added field 'accessBank' and original symbol operand
6166 in register definition,
6167 * removed the field isMapped from register definition,
6169 ** Several functions have been removed from various sources:
6170 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6171 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6172 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6173 pic16_assignRelocatableRegisters
6175 ** others have been introduced:
6176 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6177 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6179 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6181 * support/scripts/inc2h.pl: changed definition of BIT_AT
6182 to emit 'sbit at' instead of 'bit at'. This was a request.
6184 PIC16 port related preliminary changes:
6185 * gen.c: prefixed function popRegFromString with
6186 pic16_ and all references to it corrected
6187 * pcode.c: all pic16_pc_* hardware registers prefixed
6188 with underscore (_),
6189 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6190 * ralloc.c: newReg(): when register is REG_SFR then
6191 set address to rIdx,
6192 pic16_allocProcessorRegister(): marks register wasUsed=0
6193 pic16_writeUsedRegs(): added a call to assign processor
6194 registers via pic16_assignFixedRegisters
6196 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6198 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6199 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6200 variables in unused register banks. Also the SSEG is placed
6201 wherever there is enough space for it, and IDATA can be anywhere
6202 in internal RAM. For now compile using -Wl-Y[stack_size].
6203 The mem file is different for this option as well, since it
6204 makes no sense of talking about DSEG lenght.
6206 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6208 * src/SDCClrange.c: fixed bug 869095 that caused segfault

6453 * src/SDCCast.c (decorateType): disabled a transformation I added in
6454 revision 1.188 (access to fields of a structure at an absolute address);
6455 it breaks with bitfields, extern declarations, and gcse analysis.
6456 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
6457 could be assigned through a pointer, so don't complain.

7181 reported in bug #800609
7183 2003-09-04 Vangelis Rokas <vrokas AT otenet.gr>
7185 * Top header beautifications in src/pic16 directory:
7186 device.c, device.h, gen.c, gen.h, genarith.c, glue.c, pcode.c,
7187 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
7188 pcoderegs.h, ralloc.c, ralloc.h
7189 * main.c: added top header and GPL license notice
7190 * pcode.c: fixed the if-conditional warning
7192 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
7194 * device/lib/_mullong.c: replaced int by short for gcc
7196 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7198 * src/SDCCpeeph.c (notVolatile, notVolatileVariable): handle IFX
7199 and JUMPTABLE iCodes properly now (worked by accident before)
7200 * src/mcs51/gen.c (leftRightUseAcc),
7201 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
7202 iCode properly now. Use getSize instead of nRegs since a & b
7203 aren't part of the nRegs tally.
7205 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
7207 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()
7208 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
7209 before instructions that use the _STATUS register
7211 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
7213 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
7214 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7215 fetching of the pointer
7216 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7217 copied from genNearPointerSet()
7218 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7219 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
7220 If they pop r0/r1 they must be called in the opposite order than aopOp().
7221 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
7222 (resp. --stack-auto), prepared for --xstack
7224 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

7228 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7230 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
7231 these ports have their own __sdcc_external_start()
7233 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7235 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7236 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7237 type for bits was changed. It resulted in bit variables becoming
7238 global, which is not permitted in PIC 14 assembly output.
7240 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7242 * doc/sdccman.lyx: various additions and updates. Rearranged sections
7244 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7246 Z80 and MCS51 linkers complaint if a public symbol is defined
7247 in more than one library module:
7251 * as/mcs51/Makefile.in
7253 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7255 A few small changes that speed up the peephole optimizer.
7259 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7261 Try to make the peephole optimizer smarter by maintaining
7262 an association between the assembly source code and the
7263 iCodes that originated them. Put this information to use
7264 with a new peephole rule condition "notVolatile" so that
7265 the rules can be aggressive yet still safe.
7270 * src/mcs51/peeph.def
7272 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7276 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7277 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7278 if the left or right operand symbols have the accuse flag set.
7280 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7282 Changed the type of the result of the ! (NOT) operator to char;
7283 previously it returned the same type as the source. This allows
7284 us to eliminate all the genFloatNot functions (all of its target
7285 implementations were very buggy) since !float can use the same
7288 * src/SDCCicode.c (ast2iCode): ! returns char
7289 * src/mcs51/gen.c (genNot, genNotFloat),
7290 * src/ds390/gen.c (genNot, genNotFloat),
7291 * src/z80/gen.c (genNot, genNotFloat),
7292 * src/pic/gen.c (genNot, genNotFloat),
7293 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
7295 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
7297 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7298 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7299 during interrupts. Ensure WSAVE is located at a shared bank address.
7300 2. Fixed page selection in some places
7301 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7302 the registers name strings.
7303 4. Fixed "signed / unsigned compare" compiler warnings.
7304 5. The PIC port manages its own allocation of the general purpose
7305 registers, but makes no attempt to reuse them. As a result when
7306 compiling it soon runs out of general purpose registers. Some
7307 additional code was added to the files pcode.c and device.c to walk
7308 through the function call tree and rename the registers so that they
7318 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7319 genPlus() & genMinus() when the result is the same as left or right
7321 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7325 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7327 Made bitfield a distinct type from bit so that bitfields
7328 convert as per ANSI C and bits retain their traditional
7329 boolean style behaviour. Implemented bitfield support in
7337 * src/ds390/gen.c: bit v bitfield split
7338 * src/z80/gen.c: New support for bitfields
7339 * support/regression/tests/bitfields.c: reenabled z80,
7342 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7344 Rules 246.x, 247.x relate to bitfields, the others speed up
7345 access to xdata mapped I/O devices.
7347 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7349 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7351 Cleaned up genPackBits and genUnpackBits and added two helper
7352 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7353 for literal assignments in genPackBits (thanks to Frieder for
7359 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7361 Fixed bug #748310 (pointer to function type mishandled when the
7362 function name is omitted). Also fixed a SIGSEGV when a function
7363 attribute (reentrant, etc) is used on a non-function or on a
7364 function but misplaced before the parameter list.
7366 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7368 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7369 * support/Util/SDCCerr.h,
7370 * support/Util/SDCCerr.c: Added func attr misuse error msg
7372 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
7374 Fixed bug #787649 by anonymous
7375 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
7376 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
7378 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7391 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7393 Made the constant following the "interrupt" keyword optional. If
7394 omitted, the function will not automatically be given an entry
7395 in the interrupt vector table (similar to #pragma NOIV, but
7396 less syntacticly kludgy). The interrupt number is also now
7397 range checked. Also fixed a bug in the high order bit example
7404 * support/Util/SDCCerr.c
7405 * support/Util/SDCCerr.h
7408 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

7411 * src/SDCCicode.c (operandOperation): rewritten some ops
7412 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7413 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7415 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7416 be re-activated by defining REDUCE_LITERALS)
7417 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7418 unsigned, but are signed by default
7419 * src/SDCCval.c (constVal): rearranged
7420 * src/SDCCval.c (valMod): preliminary fix
7421 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7464 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
7465 * src/SDCCval.c (valDiv, valMod): fixed signdness
7466 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
7467 signedness of modulo, left and right shift

7873 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
7874 the regression tests I'm not brave enough to enable 245.b, 245.c
7875 * doc/sdccman.lyx: added latex preamble for hyperref package.
7876 Using pdflatex this will give you a hyperlinked pdf file with
7877 bookmarks. (prepend '%' before /usepackage if this breaks something)

7893 Applied patch from bug 737905 (renamed yylineo to mylineno):
7900 * src/pic16/pcode.c: Cleaned warnings
7901 * src/pic16/pcodeflow.c: Cleaned warnings
7902 * src/pic16/pcoderegs.c: Cleaned warnings

7915 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
7917 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
7918 it can be defined with CFLAGS when running configure
7919 * src/SDCCmain.c: fixed compiling + linking with object files
7921 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
7923 * configure.in: configure for pic16 port,
7924 added --disable-pic16-port
7925 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7926 * src/SDCCmain.c: linkOptions is changed to set *,
7927 added if/endif conditional macros to remove options help
7928 messages from optionsTable when a port is not configured, added
7929 support for the PIc16 port in the ports table, when executing
7930 the compiler with no port specified on command line, a default
7931 port is selected with the new macro DEFAULT_PORT which is
7932 defined in port.h, in setDefaultOptions() linkOptions is removed
7933 from initialization assignment, since now it is a set,
7934 parseCmdLine uses setParseWithComma for linkOptions, in
7935 linkEdit() linkOptions are accessed with new function indexSet()
7936 which returns the i'th item of a set variable. See SDCCset.c, in
7937 linkEdit() when calling buildCmdLine(), added linkOptions as
7938 last argument. Now users can pass arguments to gplink via the
7939 -Wl option, main() uses pic16glue() to glue up pic16 programs
7940 * src/SDCCpeeph.c: various changes to support pic16

7951 * src/pic16/glue.c: commented out some error producing lines
7952 * src/pic16/main.c: __config directives are commented out to stop
7953 gpasm complaining and test the linkage with gplink, _linkCmd and
7954 _asmCmd changed to be more gplink and gpasm friendly
7955 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7956 produced an error when parsed, peep rule 12 is added to utilize
7957 movff, but it is commented out since the pCode does not support
7958 yet a command with 2 address arguments
7960 2003-05-18 <johan AT balder>
7962 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
7963 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7987 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
7989 2003-05-11 Borut Razem <borut.razem AT siol.net>
7991 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7992 the path of bin directory, so that PATH is the only env. variable, which has to be set
7993 in case of standard installation.
7994 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

9026 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9027 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9028 following files to include the previous two files: aslink.dsp,
9029 Makefile.aslink, Makefile.bcc, and Makefile.in.
9031 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9032 .adb instead of .cdb
9034 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9036 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9037 value from option --iram-size.
9039 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9041 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9044 2002-09-18 <wiml AT hhhh.org>
9046 * SDCClrange.h: exposed setFromRange() and setToRange()
9047 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9048 packRegsForAccUse() (bug 542397)
9049 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9050 multiple times and emitting the fetch operations more than once
9051 added aopGetUsesAcc() function to allow binary operators to
9052 fetch their operands in the correct order; made genMinus() emit
9053 compact code for X = LITERAL - Y
9055 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9056 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to

9063 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9064 Changes to aslink (All the changes are marked with 'JCF'):
9066 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9069 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9070 area BSEG. Also moves, if possible, the DATA area down into the internal
9071 ram so more space is available.
9073 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9076 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9077 not bytes. Function summary() which creates a memory usage summary
9078 file with extension .mem. Reports of overlaping stack and small stack
9079 size. If the space for the stack is less than 16 bytes aslink trows a
9082 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9083 the 8051. Option 'y' for memory summary output file.
9085 Changes to sdcc (All the changes are marked with 'JCF'):
9087 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9089 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9090 overlaying area for it (uses RegBankUsed[4]).
9092 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9093 bank zero as used by default. By default aslink locates the stack
9094 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9095 the creation of the .mem file. Delegates the allocation of data area
9096 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9097 the begining of the stack area to aslink.
9099 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9100 glue() in SDCCglue.c creates an area for it.

9103 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9104 sdcc/src/pic/glue.c:
9105 introduced atexit() handler for teporay files removal in case of
9106 errors, assertions, ...
9108 2002-08-29 Borut Razem <borut.razem AT siol.net>
9109 * sdcc/support/cpp2/auto-host_vc_in.h:
9110 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9111 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9112 Maybe there is a similar problem with BORLANDC? It should be checked!
9114 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9115 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9116 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9117 was not executed, and the compiler (cl) launched a warning:
9118 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9120 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9121 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9123 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9124 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9126 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9127 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9128 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9129 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9130 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9131 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9132 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9133 - added Release configuration in VS projects
9134 - review of compiler an linker options
9135 - VC .exe files are generated in bin_vc directory, not to interfere
9136 with binaries generated from other projects (cygwin, mingw, bcc ...)
9138 * sdcc/src/yacc.dsp: added
9140 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9141 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9142 and insert the version number definitions from .version
9144 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9146 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9147 added - genarate auto-host.h using auto-host_vc_in.h as template
9150 removed from CVS, generated automatically
9152 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9153 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9155 2002-08-11 Borut Razem <borut.razem AT siol.net>
9156 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9158 2002-08-10 Borut Razem <borut.razem AT siol.net>
9159 * src/SDCCmain.c (main):
9160 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9161 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9162 The consequence was that some temporary files were not removed.
9165 unification of code in functions tempfilename() and tempfile():
9166 function tempnam() is defined in Visual Studio 6.0 and .NET
9168 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9170 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9171 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9172 - removed compiler command line option /WX: Treats all warnings as errors
9173 - update a list of source files, included into the project
9175 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9176 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9177 changed project type to Generic Project so that can be correcly converted to VS.NET project
9179 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9181 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9183 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9185 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9186 added return 0 statements after assert() to make compiler happy
9188 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9189 added newline in the def file to keep MSC compiler satisfied
9191 * sdcc/src/z80/gen.c:
9192 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9193 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9194 - solved MSC error in function aopDump()
9196 * sdcc_vc.h: define PREFIX as "\\sdcc"
9198 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9199 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

9247 Added -p option. Allows port dependent processor to be specified.
9250 Initialized the new field char *Processor field to NULL in all ports
9253 Compiler generated registers for interrupt context saving
9254 were not getting allocated.
9256 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9259 Fixed left shift. Will promote the left side of a left shift
9260 if a) left shifting more than size of operand or b) when assigned
9261 to something size > size of left side
9263 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9265 tons of changes. Register allocation has been
9266 rewritten. Added customization for the various PICs. Flow

9373 * sdcc/src/SDCCloop.c:
9374 Previous fix was not good. basic blocks that have "break" or "return" are
9375 not really partof a loop , but live ranges used in these blocks should
9376 be live thru the entire loop, so set partOfLoop but don't add them to
9379 2002-02-21 <johan AT FRIJA>
9381 * src/SDCCcse.c: fixed bug #514308
9383 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

9389 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
9391 2002-02-10 Karl Bongers <karl AT turbobit.com>
