1960 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1962 * device/lib/printf_large.c: removed inline assembly for portability and
1963 readability. Use printf_fast if speed or size are more important.
1964 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1965 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1967 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1969 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1970 prevent compiler warning
1972 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1974 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1975 moved to level 0 and declared as static. Also they are explicit
1976 placed in access bank. This was necessery because some times they
1977 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1978 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1979 optimizations. Currently only compare to unsigned char is implemented,
1980 * src/pic16/gen.c: added fReturnIdx array,
1981 * (struct resolvedIfx) is moved to gen.h and made public,
1982 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1983 * (aopForSym): added an optimization to directly store in stack of
1984 the operand of a SEND iCode,
1985 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1986 but as registers instead (AOP_REG) using the fReturnIdx array,
1987 * (pic16_freeAsmop): remove the freed register from the
1988 _G.sregsAlloc field,
1989 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1990 a compare of 'WREG',
1991 * (pic16_popGetTempRegCond): changed function prototype, now
1992 function takes also a bitVector argument v which holds the current
1993 set of registers that are allocated for stack access by aopForSym,
1994 registers allocated in aopForSym for accessing stack symbols are not
1995 any more part of the functions usedRegs field,
1996 * (genCall): some times aopOp is called for a stack variable to be
1997 send, aopForSym might perform the push, if this is true make sure
1998 that genCall doesn't push the variable twice by testing _G.resDirect,
1999 * (genFunction): changed testing for unspecified interrupt number
2000 from 256 to INTNO_UNSPEC,
2001 * modified selection scheme of frame pointer generation. Previously
2002 if function did use local registers a frame pointer was generated,
2003 now a frame pointer is generated only if function has arguments
2004 (that need PLUSW2 register access), or has stack arguments, or the
2005 compiler is not instructed to omit the frame pointer,
2006 * (genEndFunction): before restoring local registers that were saved
2007 in the function preamble, also restore the registers that *might*
2008 have been allocated for stack access,
2009 * (genRet): removed some old comments,
2010 * (genCmp, the active (RN's) version): added a call to the
2011 pic16_genCmp_special function to perform the compare with a more
2012 robust and optimized way,
2013 * (genInline): a feature has been added in inline code generation,
2014 which allows a wildcard variable substitution when writing inline
2015 assembly. Code is incomplete and experimental therefore undocumented,
2016 * (genCast): changed order of aopOp for result and right to allow
2017 aopForSym to directly load the result if possible,
2018 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2019 perform an optimized compare on some selected special occasions,
2020 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2021 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2022 generate an IVT any more,
2023 * src/pic16/main.c (pic16_optionsTable): added command line option
2025 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2026 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2028 * src/pic16/NOTES: Raphael Neider added in list of active developers
2029 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2030 jumptable_end to prevent bug #,
2031 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2032 inCond and outCond fields,
2033 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2034 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2035 turn off register spilling,
2036 * (packRegsForOneUse): synced with other ports' versions although it
2037 is not used currently,
2038 * (pic16_packRegisters): added an optimization while reading
2039 structure bitfields, some registers may be saved (malloc code is
2040 decreased by 80 bytes)
2042 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2044 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2045 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2046 this can be optimized more?
2048 2005-03-10 Raphael Neider <rneider AT web.de>
2050 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2051 genNearPointerGet): (hopefully) fixed access to bitfields via
2052 pointers (p->bitN = x; and x = p->bitN; failed)

2686 Adding support for replacing ljmps with sjmps in jumptables
2687 generated for switch statements. For now you need to set the
2688 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2689 Now 4 algorithms for mcs51 jumptable generation are used:
2690 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2691 addresses loaded pc-relative for up to 112 cases and stack-pushing
2692 target addresses loaded with offset from dptr for up to 256 cases.

2722 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2724 * added libc directory. The current version of LibC contains string
2725 functions, ctype functions and macros and some functions of the
2726 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2727 be extensively tested in the future. Standard disclaimer here.
2728 Library is not automatically build yet. But one can build it by
2729 invoking 'make' inside the libc directory.
2730 * added ADC library under libio. Preliminary version yet.

2739 * (genUminusFloat): fixed for pic16, ported code from mcs51,
2740 * (pic16_storeForReturn): optimized return of 0,
2741 * (genCmp): experimental code for new genCmp which uses PIC18's
2742 special compare&skip instructions. Initial tests fail some times
2743 with variables grater than 1 byte in size, so new code is disabled,
2744 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2746 * (genCast): began a fix to optimize the casting of a bit to another
2747 bit, now assigning a bitfield to another bitfield will fail, sorry,
2748 * src/pic16/main.c: disabled the use of lr-support feature,
2749 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

2752 bits with offset (case PO_GPR_BIT),
2753 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
2755 * (isBankInstruction): modified to return 0 for no banking instruction,
2756 and 1 for banking instruction,
2757 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2758 caused stop processing pCodes after a inline assembly block,
2759 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

2761 registers when it shouldn't,
2762 * src/pic16/ralloc.c (allocReg): add preliminary support for
2763 supporting a limited set of temporary registers,
2765 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2767 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
2768 genDataPointerSet): ensure assignments always copy in MSB to LSB
2770 (loadRegFromAop): recognize CLRH optimization,
2771 (genFunction): optimize RECEIVE iCodes in reentrant functions
2773 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2775 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

5686 * src/SDCCast.c: added an additional type flow in decorateType() of
5687 opposite direction, see feature request #860006; it's enabled at runtime
5688 by setting the environment variable SDCC_NEWTYPEFLOW
5689 * src/SDCCast.h: changed prototype of decorateType()
5690 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
5691 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
5692 'char' to 'int' can be omitted, if both operands are 'unsigned char';
5693 see feature request #877103
5694 * src/SDCCval.c: updated call of decorateType()
5695 (valBitwise): fixed bug #882876
5696 (valMinus): added promotion
5697 (valLogicAndOr): result is unsigned
5698 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
5699 * src/SDCCsymt.c (computeType),
5700 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
5701 must not cause an unsigned operation
5702 * src/pic/glue (pic14emitRegularMap),
5703 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
5705 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>
5707 * src/pic/pcode.c (PCodeID): commented out left over debug code
5709 2004-01-20 Bernhard Held <bernhard AT bernhardheld.de>
5711 * support/valdiag/tests/overflow.c: added shift tests

5720 * src/pic/pcoderegs.c,
5722 * src/pic/ralloc.h: applied patch from Slade Rich;
5723 added support for multiple code pages and multiple RAM banks on the
5724 PIC 14 port. The ASM files now no longer simply assume all the
5725 code / RAM are in the same page / bank. This means the linker can
5726 safely allocate code/RAM of separate ASM files to different pages/banks.
5727 * doc/sdccman.lyx: added Slade's tips
5728 * src/mcs51/peeph.def: fixed bug #880768

5737 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
5740 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
5741 strtof is not part of C89 and isn't included with Mac OS X.
5743 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5745 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

5767 * src/ds390/gen.c (aopOp3): fixed the assignment of different dptrs to
5770 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5772 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5773 loaded with the linker search paths (-L arguments) and the libraries
5774 to be linked with the current source (-l arguments). Changes
5775 currently will affect only the pic16 port.
5776 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5777 include path the port specific paths and port specific libraries,
5778 * gplink command now contains the $3 argument,
5779 * src/pic16/device.h,
5780 * src/pic16/device.c,: structure PIC_device is made public and
5781 renamed to PIC16_device, the same for variable Pics which is renamed
5782 to Pics16. Updated all references to them.
5783 * src/pic16/glue.c (pic16glue): corrected bug with code
5784 initialization which bypassed the variable initializations block.

5794 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
5796 Documenting changes from previous commits.
5797 * configure.in (version 1.56),
5798 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5799 when generating output files to configure the pic16 library,
5800 but now I've commented it out, since gputils aren't installed in the
5801 SF compile farm, so library won't compile
5803 * device/lib/Makefile.in (version 1.56): initially I've added in
5804 target 'all' the prerequestive 'model-pic16' so it compiled the
5805 pic16 library, but now I've commented it out for the same reasons
5807 * added targets 'model-pic16' and 'objects-pic16' to compile the
5809 * added target 'port-specific-objects-pic16' to handle the
5810 generated libraries and copy them into the build/ directory
5811 * added target 'clean-intermediate-pic16' to clean intermediate
5812 files into pic16 directory
5813 * in target 'installdirs' added line to create directory pic16 in
5814 the installation path
5816 * device/include/Makefile.in (version 1.11): in target 'install'
5817 added lines to copy all header files to installation path,
5818 * in target 'installdirs' added line create directory for pic16
5819 headers in the installation path

5834 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5835 option so that it actually works. Made it specific to the z80, since
5836 the gbz80 doesn't have these kinds of I/O ports.
5838 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5840 * device/include/z180.h,

5853 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5855 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
5856 changed interrupt vector table generation to only emit declared vectors.
5857 * device/include/Makefile.in: added missing backslash
5858 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)

5862 Mainly changes to support compilation of the device libraries
5863 * src/pic16/device.c: stack is allocated via symbol and not
5864 via literal number. The symbol is placed in the corresponding
5865 position of the data ram
5866 * (pic16_dump_section): relocatable and absolute uninitialized
5867 data are now emitted in sorted order to reduce section naming,
5868 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5869 weren't marked as being in the access bank,
5871 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5873 Added portion of GNU PIC Library under the directory
5874 device/include/pic16 and device/lib/pic16. These files
5875 contain the declarations of SFRs for the PIC18Fxx2 devices.
5876 The directory is initialized via configure from toplevel.
5878 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
5880 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

5906 all over. Telling LaTeX to be less strict with word spacing
5907 to better keep the right margin. Changed some notes about
5908 maintainance of the ports in section 3.2.1 - is it OK like this?
5910 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5948 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5950 * src/pic16/peeph.def: all peepholes with movff are commented out,
5951 because there is a problem in the pcode peep optimizer,
5952 * src/pic16/ralloc.c: the register allocator can now reuse local

6093 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6095 * sdcc.spec: updated

6104 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6106 PIC16 port related changes:
6107 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6108 added variable stackPos,
6110 * gen.c: genCall, assignResultValue: added support for
6111 pushing/retrieving function parameters to/from stack,
6112 genFunction,genEndFunction: setup stack frame for the
6114 genAddrOf: will be changed according to bug 863624
6116 * added files genutils.c and genutils.h which contain gen*
6117 debugged and optimised functions extracted from gen.c
6119 * glue.c: added variable 'externs' which holds extern symbols,
6120 pic16emitRegularMap: is modified to properly handle relocatable
6121 symbols under the new scheme,
6122 pic16createInterruptVect: is modified
6123 pic16printPublics: is modified to emit 'global' assembler directives,
6124 added pic16_printExterns to print extern symbols,
6125 pic16glue: initializes stack/frame pointer in the beginning of
6126 the assembly output. Temporary hack, will be corrected later,
6127 because gplink yet does not support stack and SDCC does not
6128 yet support a type of crt0.o object to create the final binary.
6130 * Removed many lines that contain 8051 legacy code.
6131 * The code is finally placed under a 'code' directive.
6132 * Added port specific options.
6134 * _process_pragma: simplified since now we do not need *special*
6135 include file to define SFR registers. But a separate header
6136 will be needed. This will be developed later.
6137 * _pic16_parseOptions: added, parses port specific options:
6138 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6139 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6140 --preplace-udata-with=
6142 * _pic16_setDefaultOptions: modified to initialize section names,
6143 but hack is temporarly out of order since it needs improvement.
6144 * _pic16_genAssemblerPreamble: configuration words are emitted by
6145 their address instead of their name. This part is incomplete and
6146 supports only the 18Fxx2 devices. Other devices will emit an error
6147 during assembly since they do not contain the same set of config
6149 * _pic16_genIVT: is modified,
6151 * pcode.c: added definitions for some hardware registers that are needed
6153 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6154 All PCI entries are updated. Now LFSR is supported.
6155 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6156 * added pic16_newpCodeOpLit2 to support instructions with
6157 two literal arguments
6158 * pic16_pCode2str: corrected code that emits assembler instructions
6159 with two literal operands and those that have an access bit modifier
6160 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6161 this fixes a bug which caused some labels to be lost, when an
6162 assembler directive was added, i.e. banksel,
6163 * pic16_FixRegisterBanking: improved logic that causes the insertion
6165 * InlineFunction: functions that are called once, are not any more
6166 inlined. This can be a port option in the future,
6168 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6170 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6171 hold the corresponding uninitialized symbols,
6172 * pic16_allocProcessorRegister: registers have explicit marked the
6174 * pic16_allocInternalRegister: registers are explicit marked as
6176 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6177 processing list, so bit registers were lost,
6180 * ralloc.h: added field 'accessBank' and original symbol operand
6181 in register definition,
6182 * removed the field isMapped from register definition,
6184 ** Several functions have been removed from various sources:
6185 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6186 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6187 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6188 pic16_assignRelocatableRegisters
6190 ** others have been introduced:
6191 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6192 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6194 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6196 * support/scripts/inc2h.pl: changed definition of BIT_AT
6197 to emit 'sbit at' instead of 'bit at'. This was a request.
6199 PIC16 port related preliminary changes:
6200 * gen.c: prefixed function popRegFromString with
6201 pic16_ and all references to it corrected
6202 * pcode.c: all pic16_pc_* hardware registers prefixed
6203 with underscore (_),
6204 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6205 * ralloc.c: newReg(): when register is REG_SFR then
6206 set address to rIdx,
6207 pic16_allocProcessorRegister(): marks register wasUsed=0
6208 pic16_writeUsedRegs(): added a call to assign processor
6209 registers via pic16_assignFixedRegisters
6211 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6213 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6214 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6215 variables in unused register banks. Also the SSEG is placed
6216 wherever there is enough space for it, and IDATA can be anywhere
6217 in internal RAM. For now compile using -Wl-Y[stack_size].
6218 The mem file is different for this option as well, since it
6219 makes no sense of talking about DSEG lenght.
6221 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6223 * src/SDCClrange.c: fixed bug 869095 that caused segfault

6468 * src/SDCCast.c (decorateType): disabled a transformation I added in
6469 revision 1.188 (access to fields of a structure at an absolute address);
6470 it breaks with bitfields, extern declarations, and gcse analysis.
6471 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
6472 could be assigned through a pointer, so don't complain.

7229 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7230 fetching of the pointer
7231 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7232 copied from genNearPointerSet()
7233 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7234 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
7235 If they pop r0/r1 they must be called in the opposite order than aopOp().
7236 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
7237 (resp. --stack-auto), prepared for --xstack

7248 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7250 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7251 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7252 type for bits was changed. It resulted in bit variables becoming
7253 global, which is not permitted in PIC 14 assembly output.
7255 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7257 * doc/sdccman.lyx: various additions and updates. Rearranged sections
7259 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7261 Z80 and MCS51 linkers complaint if a public symbol is defined

7270 A few small changes that speed up the peephole optimizer.
7274 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7276 Try to make the peephole optimizer smarter by maintaining
7277 an association between the assembly source code and the
7278 iCodes that originated them. Put this information to use
7279 with a new peephole rule condition "notVolatile" so that
7280 the rules can be aggressive yet still safe.
7285 * src/mcs51/peeph.def
7287 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7291 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7292 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7293 if the left or right operand symbols have the accuse flag set.
7295 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7297 Changed the type of the result of the ! (NOT) operator to char;
7298 previously it returned the same type as the source. This allows
7299 us to eliminate all the genFloatNot functions (all of its target
7300 implementations were very buggy) since !float can use the same
7303 * src/SDCCicode.c (ast2iCode): ! returns char

7305 * src/ds390/gen.c (genNot, genNotFloat),
7306 * src/z80/gen.c (genNot, genNotFloat),
7307 * src/pic/gen.c (genNot, genNotFloat),

7312 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7313 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7314 during interrupts. Ensure WSAVE is located at a shared bank address.
7315 2. Fixed page selection in some places
7316 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7317 the registers name strings.
7318 4. Fixed "signed / unsigned compare" compiler warnings.
7319 5. The PIC port manages its own allocation of the general purpose
7320 registers, but makes no attempt to reuse them. As a result when
7321 compiling it soon runs out of general purpose registers. Some
7322 additional code was added to the files pcode.c and device.c to walk
7323 through the function call tree and rename the registers so that they
7333 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7334 genPlus() & genMinus() when the result is the same as left or right

7340 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7342 Made bitfield a distinct type from bit so that bitfields
7343 convert as per ANSI C and bits retain their traditional
7344 boolean style behaviour. Implemented bitfield support in
7352 * src/ds390/gen.c: bit v bitfield split
7353 * src/z80/gen.c: New support for bitfields
7354 * support/regression/tests/bitfields.c: reenabled z80,
7357 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7359 Rules 246.x, 247.x relate to bitfields, the others speed up
7360 access to xdata mapped I/O devices.
7362 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7364 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7366 Cleaned up genPackBits and genUnpackBits and added two helper
7367 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7368 for literal assignments in genPackBits (thanks to Frieder for
7374 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7376 Fixed bug #748310 (pointer to function type mishandled when the
7377 function name is omitted). Also fixed a SIGSEGV when a function
7378 attribute (reentrant, etc) is used on a non-function or on a
7379 function but misplaced before the parameter list.
7381 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7383 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

7406 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7408 Made the constant following the "interrupt" keyword optional. If
7409 omitted, the function will not automatically be given an entry
7410 in the interrupt vector table (similar to #pragma NOIV, but
7411 less syntacticly kludgy). The interrupt number is also now
7412 range checked. Also fixed a bug in the high order bit example
7419 * support/Util/SDCCerr.c
7420 * support/Util/SDCCerr.h
7423 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

7426 * src/SDCCicode.c (operandOperation): rewritten some ops
7427 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7428 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7430 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7431 be re-activated by defining REDUCE_LITERALS)
7432 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7433 unsigned, but are signed by default
7434 * src/SDCCval.c (constVal): rearranged
7435 * src/SDCCval.c (valMod): preliminary fix
7436 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7888 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
7889 the regression tests I'm not brave enough to enable 245.b, 245.c

7891 Using pdflatex this will give you a hyperlinked pdf file with
7892 bookmarks. (prepend '%' before /usepackage if this breaks something)

7941 * src/SDCCmain.c: linkOptions is changed to set *,
7942 added if/endif conditional macros to remove options help
7943 messages from optionsTable when a port is not configured, added
7944 support for the PIc16 port in the ports table, when executing
7945 the compiler with no port specified on command line, a default
7946 port is selected with the new macro DEFAULT_PORT which is
7947 defined in port.h, in setDefaultOptions() linkOptions is removed
7948 from initialization assignment, since now it is a set,
7949 parseCmdLine uses setParseWithComma for linkOptions, in
7950 linkEdit() linkOptions are accessed with new function indexSet()
7951 which returns the i'th item of a set variable. See SDCCset.c, in
7952 linkEdit() when calling buildCmdLine(), added linkOptions as
7953 last argument. Now users can pass arguments to gplink via the
7954 -Wl option, main() uses pic16glue() to glue up pic16 programs

7966 * src/pic16/glue.c: commented out some error producing lines
7967 * src/pic16/main.c: __config directives are commented out to stop
7968 gpasm complaining and test the linkage with gplink, _linkCmd and
7969 _asmCmd changed to be more gplink and gpasm friendly
7970 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7971 produced an error when parsed, peep rule 12 is added to utilize
7972 movff, but it is commented out since the pCode does not support
7973 yet a command with 2 address arguments
7975 2003-05-18 <johan AT balder>
7977 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8004 2003-05-11 Borut Razem <borut.razem AT siol.net>
8006 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
8007 the path of bin directory, so that PATH is the only env. variable, which has to be set
8008 in case of standard installation.

9093 file with extension .mem. Reports of overlaping stack and small stack
9094 size. If the space for the stack is less than 16 bytes aslink trows a
9097 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9098 the 8051. Option 'y' for memory summary output file.
9100 Changes to sdcc (All the changes are marked with 'JCF'):
9102 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9104 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9105 overlaying area for it (uses RegBankUsed[4]).
9107 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9108 bank zero as used by default. By default aslink locates the stack
9109 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9110 the creation of the .mem file. Delegates the allocation of data area
9111 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9112 the begining of the stack area to aslink.
9114 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9115 glue() in SDCCglue.c creates an area for it.
9117 2002-09-03 Borut Razem <borut.razem AT siol.net>
9118 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9119 sdcc/src/pic/glue.c:
9120 introduced atexit() handler for teporay files removal in case of
9121 errors, assertions, ...
9123 2002-08-29 Borut Razem <borut.razem AT siol.net>
9124 * sdcc/support/cpp2/auto-host_vc_in.h:
9125 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9126 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9127 Maybe there is a similar problem with BORLANDC? It should be checked!
9129 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9130 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9131 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9132 was not executed, and the compiler (cl) launched a warning:
9133 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9135 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9136 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9138 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9139 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9141 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9142 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9143 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9144 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9145 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9146 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9147 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9148 - added Release configuration in VS projects
9149 - review of compiler an linker options
9150 - VC .exe files are generated in bin_vc directory, not to interfere
9151 with binaries generated from other projects (cygwin, mingw, bcc ...)
9153 * sdcc/src/yacc.dsp: added
9155 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9156 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9157 and insert the version number definitions from .version
9159 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9161 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9162 added - genarate auto-host.h using auto-host_vc_in.h as template
9165 removed from CVS, generated automatically
9167 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9168 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9170 2002-08-11 Borut Razem <borut.razem AT siol.net>
9171 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9173 2002-08-10 Borut Razem <borut.razem AT siol.net>
9174 * src/SDCCmain.c (main):
9175 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9176 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9177 The consequence was that some temporary files were not removed.
9180 unification of code in functions tempfilename() and tempfile():
9181 function tempnam() is defined in Visual Studio 6.0 and .NET
9183 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9185 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9186 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9187 - removed compiler command line option /WX: Treats all warnings as errors
9188 - update a list of source files, included into the project
9190 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9191 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9192 changed project type to Generic Project so that can be correcly converted to VS.NET project
9194 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9196 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9198 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9200 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9201 added return 0 statements after assert() to make compiler happy
9203 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9204 added newline in the def file to keep MSC compiler satisfied
9206 * sdcc/src/z80/gen.c:
9207 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9208 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9209 - solved MSC error in function aopDump()
9211 * sdcc_vc.h: define PREFIX as "\\sdcc"
9213 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9214 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

9262 Added -p option. Allows port dependent processor to be specified.
9265 Initialized the new field char *Processor field to NULL in all ports
9268 Compiler generated registers for interrupt context saving
9269 were not getting allocated.
9271 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9274 Fixed left shift. Will promote the left side of a left shift
9275 if a) left shifting more than size of operand or b) when assigned
9276 to something size > size of left side
9278 2002-03-14 Scott Dattalo <scott AT dattalo.com>

9386 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
9388 * sdcc/src/SDCCloop.c:
9389 Previous fix was not good. basic blocks that have "break" or "return" are
9390 not really partof a loop , but live ranges used in these blocks should
9391 be live thru the entire loop, so set partOfLoop but don't add them to
9394 2002-02-21 <johan AT FRIJA>
9396 * src/SDCCcse.c: fixed bug #514308
9398 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

9404 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
9406 2002-02-10 Karl Bongers <karl AT turbobit.com>
9409 Fixed up SDCDB debugger somewhat. Updated debugger/README
9410 with lots of comments and notes.
9412 * device/examples/test2.c:
9413 Fix bug, "red" variable not being initialized(compiler complained).
