12 remove cast to same type
13 * src/SDCCast.c (decorateType): fix for RFE 1475742,

16 * link/z80/Makefile: removed, they have moved to
19 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
21 Enabled VPATH feature: changed nearly all Makefiles (149 files).
22 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
24 One basic decision: e.g. src/clean.mk includes further files. In order
25 to make this work there are two solutions:
26 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
27 run configure on them. This way they can use
28 'include $(srcdir)/port-clean.mk'
29 - always include clean.mk by the Makefile at the same level. To avoid
30 that `make clean` tries to include and build Makefile.dep the
31 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
32 implemented, because now even `make uninstall` doesn't create
33 Makefile.in. clean.mk could be eliminated by pasting it in
36 * debugger/mcs51/Makefile.in: build own objects from library sources
37 (SLIB, SDCC) in current directory
39 * configure, configure.in: renamed --disable-device-lib-build in
40 --disable-device-lib; added --enable-doc, the required tools are
41 searched by configure; added result message; the toolchain for the
42 belonging ports are now only built, if the port is enabled.
44 * support/regression/*: all output is written in directory gen, because
45 the fwk and ports directories don't livet in the build tree using vpath
47 * doc/sdccman.lyx: renamed --disable-device-lib-build to
48 --disable-device-lib, added --enable-doc, added section VPATH
50 * sim/ucsim/configure.in,
51 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
52 z80 are enabled by default
54 2006-04-24 Raphael Neider <rneider AT web.de>
56 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments to
57 config word, "pic14_"-prefixed some extern functions
58 (pic14_emitConfigWord): emit __config directive(s) if assignment to
59 config word has been found
60 * src/pic/device.h: added prototypes
61 * src/pic/pcode.c: added "pic14_"-prefix where needed
62 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic fixup

368 call to allocReg, not by manually allocating a new one,
369 (pic16_assignRegisters): now before going through the register
370 allocating functions mark all registers as free. This eliminates some
371 side effects resulting from peephole parser done earlier in the backbone

441 (genOr): removed some legacy pic-port instructions,
442 * src/pic16/genarith.c (genAddLit): re-enabled old code because
443 performing operations with SFR's causes data to be written more than
444 once to each SFR. Perhaps SFRs should be handled in special cases...
445 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to

2731 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
2732 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
2733 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
2734 always available in leading double underscore form. The C99 support is
2735 mostly missing, but it's a start.
2736 * support/regression/tests/bug-227710.c: fixed nonconforming use of
2737 reserved identifier "__data".

2815 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2817 * device/lib/printf_large.c: removed inline assembly for portability and
2818 readability. Use printf_fast if speed or size are more important.
2819 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2820 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2822 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2824 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2825 prevent compiler warning
2827 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2829 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2830 moved to level 0 and declared as static. Also they are explicit
2831 placed in access bank. This was necessery because some times they
2832 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2833 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2834 optimizations. Currently only compare to unsigned char is implemented,
2835 * src/pic16/gen.c: added fReturnIdx array,
2836 * (struct resolvedIfx) is moved to gen.h and made public,
2837 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2838 * (aopForSym): added an optimization to directly store in stack of
2839 the operand of a SEND iCode,
2840 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2841 but as registers instead (AOP_REG) using the fReturnIdx array,
2842 * (pic16_freeAsmop): remove the freed register from the
2843 _G.sregsAlloc field,
2844 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2845 a compare of 'WREG',
2846 * (pic16_popGetTempRegCond): changed function prototype, now
2847 function takes also a bitVector argument v which holds the current
2848 set of registers that are allocated for stack access by aopForSym,
2849 registers allocated in aopForSym for accessing stack symbols are not
2850 any more part of the functions usedRegs field,
2851 * (genCall): some times aopOp is called for a stack variable to be
2852 send, aopForSym might perform the push, if this is true make sure
2853 that genCall doesn't push the variable twice by testing _G.resDirect,
2854 * (genFunction): changed testing for unspecified interrupt number
2855 from 256 to INTNO_UNSPEC,
2856 * modified selection scheme of frame pointer generation. Previously
2857 if function did use local registers a frame pointer was generated,
2858 now a frame pointer is generated only if function has arguments
2859 (that need PLUSW2 register access), or has stack arguments, or the
2860 compiler is not instructed to omit the frame pointer,
2861 * (genEndFunction): before restoring local registers that were saved
2862 in the function preamble, also restore the registers that *might*
2863 have been allocated for stack access,
2864 * (genRet): removed some old comments,
2865 * (genCmp, the active (RN's) version): added a call to the
2866 pic16_genCmp_special function to perform the compare with a more
2867 robust and optimized way,
2868 * (genInline): a feature has been added in inline code generation,
2869 which allows a wildcard variable substitution when writing inline
2870 assembly. Code is incomplete and experimental therefore undocumented,
2871 * (genCast): changed order of aopOp for result and right to allow
2872 aopForSym to directly load the result if possible,
2873 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2874 perform an optimized compare on some selected special occasions,
2875 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2876 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2877 generate an IVT any more,
2878 * src/pic16/main.c (pic16_optionsTable): added command line option
2880 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2881 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2883 * src/pic16/NOTES: Raphael Neider added in list of active developers
2884 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2885 jumptable_end to prevent bug #,
2886 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2887 inCond and outCond fields,
2888 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2889 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2890 turn off register spilling,
2891 * (packRegsForOneUse): synced with other ports' versions although it
2892 is not used currently,
2893 * (pic16_packRegisters): added an optimization while reading
2894 structure bitfields, some registers may be saved (malloc code is
2895 decreased by 80 bytes)
2897 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2899 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2900 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2901 this can be optimized more?
2903 2005-03-10 Raphael Neider <rneider AT web.de>
2905 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2906 genNearPointerGet): (hopefully) fixed access to bitfields via
2907 pointers (p->bitN = x; and x = p->bitN; failed)

3541 Adding support for replacing ljmps with sjmps in jumptables
3542 generated for switch statements. For now you need to set the
3543 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3544 Now 4 algorithms for mcs51 jumptable generation are used:
3545 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3546 addresses loaded pc-relative for up to 112 cases and stack-pushing
3547 target addresses loaded with offset from dptr for up to 256 cases.

3574 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
3575 to call when a stack overflow occurs,
3576 * (malloc.h): added CVS Id tag,
3577 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3579 * added libc directory. The current version of LibC contains string
3580 functions, ctype functions and macros and some functions of the
3581 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3582 be extensively tested in the future. Standard disclaimer here.
3583 Library is not automatically build yet. But one can build it by
3584 invoking 'make' inside the libc directory.
3585 * added ADC library under libio. Preliminary version yet.

3591 temporary registers, its a buggy feature and will be removed,
3592 * (pic16_popGet): set register instance field in AOP_CRY,
3593 * (pic16_outBitC): fixed for results in size greater than 1,
3594 * (genUminusFloat): fixed for pic16, ported code from mcs51,
3595 * (pic16_storeForReturn): optimized return of 0,
3596 * (genCmp): experimental code for new genCmp which uses PIC18's
3597 special compare&skip instructions. Initial tests fail some times
3598 with variables grater than 1 byte in size, so new code is disabled,
3599 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3601 * (genCast): began a fix to optimize the casting of a bit to another
3602 bit, now assigning a bitfield to another bitfield will fail, sorry,
3603 * src/pic16/main.c: disabled the use of lr-support feature,
3604 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

3607 bits with offset (case PO_GPR_BIT),
3608 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
3610 * (isBankInstruction): modified to return 0 for no banking instruction,
3611 and 1 for banking instruction,
3612 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3613 caused stop processing pCodes after a inline assembly block,
3614 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
3615 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
3616 registers when it shouldn't,
3617 * src/pic16/ralloc.c (allocReg): add preliminary support for
3618 supporting a limited set of temporary registers,
3620 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3622 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
3623 genDataPointerSet): ensure assignments always copy in MSB to LSB
3625 (loadRegFromAop): recognize CLRH optimization,
3626 (genFunction): optimize RECEIVE iCodes in reentrant functions
3628 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6546 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
6547 'char' to 'int' can be omitted, if both operands are 'unsigned char';
6548 see feature request #877103
6549 * src/SDCCval.c: updated call of decorateType()
6550 (valBitwise): fixed bug #882876
6551 (valMinus): added promotion
6552 (valLogicAndOr): result is unsigned
6553 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
6554 * src/SDCCsymt.c (computeType),
6555 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
6556 must not cause an unsigned operation
6557 * src/pic/glue (pic14emitRegularMap),
6558 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
6560 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>

6577 * src/pic/ralloc.h: applied patch from Slade Rich;
6578 added support for multiple code pages and multiple RAM banks on the
6579 PIC 14 port. The ASM files now no longer simply assume all the
6580 code / RAM are in the same page / bank. This means the linker can
6581 safely allocate code/RAM of separate ASM files to different pages/banks.
6582 * doc/sdccman.lyx: added Slade's tips
6583 * src/mcs51/peeph.def: fixed bug #880768

6592 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
6595 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
6596 strtof is not part of C89 and isn't included with Mac OS X.
6598 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6600 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

6625 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6627 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6628 loaded with the linker search paths (-L arguments) and the libraries
6629 to be linked with the current source (-l arguments). Changes
6630 currently will affect only the pic16 port.
6631 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6632 include path the port specific paths and port specific libraries,
6633 * gplink command now contains the $3 argument,
6634 * src/pic16/device.h,
6635 * src/pic16/device.c,: structure PIC_device is made public and
6636 renamed to PIC16_device, the same for variable Pics which is renamed

6651 Documenting changes from previous commits.
6652 * configure.in (version 1.56),
6653 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6654 when generating output files to configure the pic16 library,
6655 but now I've commented it out, since gputils aren't installed in the
6656 SF compile farm, so library won't compile
6658 * device/lib/Makefile.in (version 1.56): initially I've added in
6659 target 'all' the prerequestive 'model-pic16' so it compiled the
6660 pic16 library, but now I've commented it out for the same reasons
6662 * added targets 'model-pic16' and 'objects-pic16' to compile the
6664 * added target 'port-specific-objects-pic16' to handle the
6665 generated libraries and copy them into the build/ directory
6666 * added target 'clean-intermediate-pic16' to clean intermediate
6667 files into pic16 directory
6668 * in target 'installdirs' added line to create directory pic16 in
6669 the installation path
6671 * device/include/Makefile.in (version 1.11): in target 'install'
6672 added lines to copy all header files to installation path,
6673 * in target 'installdirs' added line create directory for pic16
6674 headers in the installation path

6689 * src/z80/main.c (_parseOptions): fixed the portmode= command line
6690 option so that it actually works. Made it specific to the z80, since
6691 the gbz80 doesn't have these kinds of I/O ports.
6693 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6695 * device/include/z180.h,

6717 Mainly changes to support compilation of the device libraries
6718 * src/pic16/device.c: stack is allocated via symbol and not
6719 via literal number. The symbol is placed in the corresponding
6720 position of the data ram
6721 * (pic16_dump_section): relocatable and absolute uninitialized
6722 data are now emitted in sorted order to reduce section naming,
6723 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6724 weren't marked as being in the access bank,
6726 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6728 Added portion of GNU PIC Library under the directory
6729 device/include/pic16 and device/lib/pic16. These files
6730 contain the declarations of SFRs for the PIC18Fxx2 devices.
6731 The directory is initialized via configure from toplevel.
6733 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
6735 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

6761 all over. Telling LaTeX to be less strict with word spacing
6762 to better keep the right margin. Changed some notes about
6763 maintainance of the ports in section 3.2.1 - is it OK like this?
6765 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

6959 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6961 PIC16 port related changes:
6962 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6963 added variable stackPos,
6965 * gen.c: genCall, assignResultValue: added support for
6966 pushing/retrieving function parameters to/from stack,
6967 genFunction,genEndFunction: setup stack frame for the
6969 genAddrOf: will be changed according to bug 863624
6971 * added files genutils.c and genutils.h which contain gen*
6972 debugged and optimised functions extracted from gen.c
6974 * glue.c: added variable 'externs' which holds extern symbols,
6975 pic16emitRegularMap: is modified to properly handle relocatable
6976 symbols under the new scheme,
6977 pic16createInterruptVect: is modified
6978 pic16printPublics: is modified to emit 'global' assembler directives,
6979 added pic16_printExterns to print extern symbols,
6980 pic16glue: initializes stack/frame pointer in the beginning of
6981 the assembly output. Temporary hack, will be corrected later,
6982 because gplink yet does not support stack and SDCC does not
6983 yet support a type of crt0.o object to create the final binary.
6985 * Removed many lines that contain 8051 legacy code.
6986 * The code is finally placed under a 'code' directive.
6987 * Added port specific options.
6989 * _process_pragma: simplified since now we do not need *special*
6990 include file to define SFR registers. But a separate header
6991 will be needed. This will be developed later.
6992 * _pic16_parseOptions: added, parses port specific options:
6993 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6994 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6995 --preplace-udata-with=
6997 * _pic16_setDefaultOptions: modified to initialize section names,
6998 but hack is temporarly out of order since it needs improvement.
6999 * _pic16_genAssemblerPreamble: configuration words are emitted by
7000 their address instead of their name. This part is incomplete and
7001 supports only the 18Fxx2 devices. Other devices will emit an error
7002 during assembly since they do not contain the same set of config
7004 * _pic16_genIVT: is modified,
7006 * pcode.c: added definitions for some hardware registers that are needed
7008 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7009 All PCI entries are updated. Now LFSR is supported.
7010 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7011 * added pic16_newpCodeOpLit2 to support instructions with
7012 two literal arguments
7013 * pic16_pCode2str: corrected code that emits assembler instructions
7014 with two literal operands and those that have an access bit modifier
7015 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7016 this fixes a bug which caused some labels to be lost, when an
7017 assembler directive was added, i.e. banksel,
7018 * pic16_FixRegisterBanking: improved logic that causes the insertion
7020 * InlineFunction: functions that are called once, are not any more
7021 inlined. This can be a port option in the future,
7023 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7025 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7026 hold the corresponding uninitialized symbols,
7027 * pic16_allocProcessorRegister: registers have explicit marked the
7029 * pic16_allocInternalRegister: registers are explicit marked as
7031 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7032 processing list, so bit registers were lost,
7035 * ralloc.h: added field 'accessBank' and original symbol operand
7036 in register definition,
7037 * removed the field isMapped from register definition,
7039 ** Several functions have been removed from various sources:

7051 * support/scripts/inc2h.pl: changed definition of BIT_AT
7052 to emit 'sbit at' instead of 'bit at'. This was a request.
7054 PIC16 port related preliminary changes:
7055 * gen.c: prefixed function popRegFromString with
7056 pic16_ and all references to it corrected
7057 * pcode.c: all pic16_pc_* hardware registers prefixed
7058 with underscore (_),
7059 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7060 * ralloc.c: newReg(): when register is REG_SFR then
7061 set address to rIdx,
7062 pic16_allocProcessorRegister(): marks register wasUsed=0
7063 pic16_writeUsedRegs(): added a call to assign processor
7064 registers via pic16_assignFixedRegisters
7066 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7068 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7069 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7070 variables in unused register banks. Also the SSEG is placed
7071 wherever there is enough space for it, and IDATA can be anywhere
7072 in internal RAM. For now compile using -Wl-Y[stack_size].
7073 The mem file is different for this option as well, since it
7074 makes no sense of talking about DSEG lenght.
7076 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7078 * src/SDCClrange.c: fixed bug 869095 that caused segfault

7324 revision 1.188 (access to fields of a structure at an absolute address);
7325 it breaks with bitfields, extern declarations, and gcse analysis.
7326 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7327 could be assigned through a pointer, so don't complain.

8071 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
8072 iCode properly now. Use getSize instead of nRegs since a & b
8073 aren't part of the nRegs tally.
8075 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
8077 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

8083 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
8084 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8085 fetching of the pointer
8086 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8087 copied from genNearPointerSet()
8088 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8089 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
8090 If they pop r0/r1 they must be called in the opposite order than aopOp().
8091 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
8092 (resp. --stack-auto), prepared for --xstack

8103 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8105 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8106 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8107 type for bits was changed. It resulted in bit variables becoming
8108 global, which is not permitted in PIC 14 assembly output.
8110 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8112 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8125 A few small changes that speed up the peephole optimizer.
8129 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8131 Try to make the peephole optimizer smarter by maintaining
8132 an association between the assembly source code and the
8133 iCodes that originated them. Put this information to use
8134 with a new peephole rule condition "notVolatile" so that
8135 the rules can be aggressive yet still safe.
8140 * src/mcs51/peeph.def
8142 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8146 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8147 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8148 if the left or right operand symbols have the accuse flag set.
8150 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8152 Changed the type of the result of the ! (NOT) operator to char;
8153 previously it returned the same type as the source. This allows
8154 us to eliminate all the genFloatNot functions (all of its target
8155 implementations were very buggy) since !float can use the same
8158 * src/SDCCicode.c (ast2iCode): ! returns char
8159 * src/mcs51/gen.c (genNot, genNotFloat),
8160 * src/ds390/gen.c (genNot, genNotFloat),
8161 * src/z80/gen.c (genNot, genNotFloat),
8162 * src/pic/gen.c (genNot, genNotFloat),
8163 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
8165 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
8167 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8168 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8169 during interrupts. Ensure WSAVE is located at a shared bank address.
8170 2. Fixed page selection in some places
8171 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8172 the registers name strings.
8173 4. Fixed "signed / unsigned compare" compiler warnings.
8174 5. The PIC port manages its own allocation of the general purpose
8175 registers, but makes no attempt to reuse them. As a result when
8176 compiling it soon runs out of general purpose registers. Some
8177 additional code was added to the files pcode.c and device.c to walk
8178 through the function call tree and rename the registers so that they
8188 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8189 genPlus() & genMinus() when the result is the same as left or right

8195 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8197 Made bitfield a distinct type from bit so that bitfields
8198 convert as per ANSI C and bits retain their traditional
8199 boolean style behaviour. Implemented bitfield support in
8207 * src/ds390/gen.c: bit v bitfield split
8208 * src/z80/gen.c: New support for bitfields
8209 * support/regression/tests/bitfields.c: reenabled z80,
8212 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8214 Rules 246.x, 247.x relate to bitfields, the others speed up
8215 access to xdata mapped I/O devices.
8217 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8219 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8221 Cleaned up genPackBits and genUnpackBits and added two helper
8222 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8223 for literal assignments in genPackBits (thanks to Frieder for
8229 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8231 Fixed bug #748310 (pointer to function type mishandled when the
8232 function name is omitted). Also fixed a SIGSEGV when a function
8233 attribute (reentrant, etc) is used on a non-function or on a
8234 function but misplaced before the parameter list.
8236 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8238 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

8261 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8263 Made the constant following the "interrupt" keyword optional. If
8264 omitted, the function will not automatically be given an entry
8265 in the interrupt vector table (similar to #pragma NOIV, but
8266 less syntacticly kludgy). The interrupt number is also now
8267 range checked. Also fixed a bug in the high order bit example
8274 * support/Util/SDCCerr.c
8275 * support/Util/SDCCerr.h
8278 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

8281 * src/SDCCicode.c (operandOperation): rewritten some ops
8282 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8283 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8285 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8286 be re-activated by defining REDUCE_LITERALS)
8287 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8288 unsigned, but are signed by default
8289 * src/SDCCval.c (constVal): rearranged
8290 * src/SDCCval.c (valMod): preliminary fix
8291 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8334 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
8335 * src/SDCCval.c (valDiv, valMod): fixed signdness
8336 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
8337 signedness of modulo, left and right shift

8743 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
8744 the regression tests I'm not brave enough to enable 245.b, 245.c
8745 * doc/sdccman.lyx: added latex preamble for hyperref package.
8746 Using pdflatex this will give you a hyperlinked pdf file with
8747 bookmarks. (prepend '%' before /usepackage if this breaks something)

8785 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
8787 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
8788 it can be defined with CFLAGS when running configure
8789 * src/SDCCmain.c: fixed compiling + linking with object files
8791 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

8794 added --disable-pic16-port
8795 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
8796 * src/SDCCmain.c: linkOptions is changed to set *,
8797 added if/endif conditional macros to remove options help
8798 messages from optionsTable when a port is not configured, added
8799 support for the PIc16 port in the ports table, when executing
8800 the compiler with no port specified on command line, a default
8801 port is selected with the new macro DEFAULT_PORT which is
8802 defined in port.h, in setDefaultOptions() linkOptions is removed
8803 from initialization assignment, since now it is a set,
8804 parseCmdLine uses setParseWithComma for linkOptions, in
8805 linkEdit() linkOptions are accessed with new function indexSet()
8806 which returns the i'th item of a set variable. See SDCCset.c, in
8807 linkEdit() when calling buildCmdLine(), added linkOptions as
8808 last argument. Now users can pass arguments to gplink via the
8809 -Wl option, main() uses pic16glue() to glue up pic16 programs

8821 * src/pic16/glue.c: commented out some error producing lines
8822 * src/pic16/main.c: __config directives are commented out to stop
8823 gpasm complaining and test the linkage with gplink, _linkCmd and
8824 _asmCmd changed to be more gplink and gpasm friendly
8825 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8826 produced an error when parsed, peep rule 12 is added to utilize
8827 movff, but it is commented out since the pCode does not support
8828 yet a command with 2 address arguments
8830 2003-05-18 <johan AT balder>
8832 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8859 2003-05-11 Borut Razem <borut.razem AT siol.net>
8861 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
8862 the path of bin directory, so that PATH is the only env. variable, which has to be set
8863 in case of standard installation.
8864 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

9957 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9959 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9960 overlaying area for it (uses RegBankUsed[4]).
9962 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9963 bank zero as used by default. By default aslink locates the stack
9964 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9965 the creation of the .mem file. Delegates the allocation of data area
9966 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9967 the begining of the stack area to aslink.
9969 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9970 glue() in SDCCglue.c creates an area for it.
9972 2002-09-03 Borut Razem <borut.razem AT siol.net>
9973 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9974 sdcc/src/pic/glue.c:
9975 introduced atexit() handler for teporay files removal in case of
9976 errors, assertions, ...
9978 2002-08-29 Borut Razem <borut.razem AT siol.net>
9979 * sdcc/support/cpp2/auto-host_vc_in.h:
9980 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9981 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9982 Maybe there is a similar problem with BORLANDC? It should be checked!
9984 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9985 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9986 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9987 was not executed, and the compiler (cl) launched a warning:
9988 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9990 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9991 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9993 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9994 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9996 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9997 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9998 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9999 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10000 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10001 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10002 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10003 - added Release configuration in VS projects
10004 - review of compiler an linker options
10005 - VC .exe files are generated in bin_vc directory, not to interfere
10006 with binaries generated from other projects (cygwin, mingw, bcc ...)
10008 * sdcc/src/yacc.dsp: added
10010 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10011 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10012 and insert the version number definitions from .version
10014 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10016 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10017 added - genarate auto-host.h using auto-host_vc_in.h as template
10020 removed from CVS, generated automatically
10022 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10023 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10025 2002-08-11 Borut Razem <borut.razem AT siol.net>
10026 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10028 2002-08-10 Borut Razem <borut.razem AT siol.net>
10029 * src/SDCCmain.c (main):
10030 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10031 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10032 The consequence was that some temporary files were not removed.
10035 unification of code in functions tempfilename() and tempfile():
10036 function tempnam() is defined in Visual Studio 6.0 and .NET
10038 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10040 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10041 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10042 - removed compiler command line option /WX: Treats all warnings as errors
10043 - update a list of source files, included into the project
10045 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10046 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10047 changed project type to Generic Project so that can be correcly converted to VS.NET project
10049 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10051 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10053 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10055 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10056 added return 0 statements after assert() to make compiler happy
10058 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10059 added newline in the def file to keep MSC compiler satisfied
10061 * sdcc/src/z80/gen.c:
10062 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10063 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10064 - solved MSC error in function aopDump()
10066 * sdcc_vc.h: define PREFIX as "\\sdcc"
10068 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10069 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10117 Added -p option. Allows port dependent processor to be specified.
10120 Initialized the new field char *Processor field to NULL in all ports
10123 Compiler generated registers for interrupt context saving
10124 were not getting allocated.
10126 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10129 Fixed left shift. Will promote the left side of a left shift
10130 if a) left shifting more than size of operand or b) when assigned
10131 to something size > size of left side

10241 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10243 * sdcc/src/SDCCloop.c:
10244 Previous fix was not good. basic blocks that have "break" or "return" are
10245 not really partof a loop , but live ranges used in these blocks should
10246 be live thru the entire loop, so set partOfLoop but don't add them to
10249 2002-02-21 <johan AT FRIJA>
10251 * src/SDCCcse.c: fixed bug #514308
10253 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

10257 statement inside a loop, it was not being considered part of the loop.
10259 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
10261 2002-02-10 Karl Bongers <karl AT turbobit.com>
