39 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
41 Enabled VPATH feature: changed nearly all Makefiles (149 files).
42 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
44 One basic decision: e.g. src/clean.mk includes further files. In order
45 to make this work there are two solutions:
46 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
47 run configure on them. This way they can use
48 'include $(srcdir)/port-clean.mk'
49 - always include clean.mk by the Makefile at the same level. To avoid
50 that `make clean` tries to include and build Makefile.dep the
51 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
52 implemented, because now even `make uninstall` doesn't create
53 Makefile.in. clean.mk could be eliminated by pasting it in
56 * debugger/mcs51/Makefile.in: build own objects from library sources
57 (SLIB, SDCC) in current directory
59 * configure, configure.in: renamed --disable-device-lib-build in
60 --disable-device-lib; added --enable-doc, the required tools are
61 searched by configure; added result message; the toolchain for the
62 belonging ports are now only built, if the port is enabled.
64 * support/regression/*: all output is written in directory gen, because
65 the fwk and ports directories don't livet in the build tree using vpath
67 * doc/sdccman.lyx: renamed --disable-device-lib-build to
68 --disable-device-lib, added --enable-doc, added section VPATH
70 * sim/ucsim/configure.in,
71 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
72 z80 are enabled by default
74 2006-04-24 Raphael Neider <rneider AT web.de>
76 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments to
77 config word, "pic14_"-prefixed some extern functions
78 (pic14_emitConfigWord): emit __config directive(s) if assignment to
79 config word has been found
80 * src/pic/device.h: added prototypes
81 * src/pic/pcode.c: added "pic14_"-prefix where needed
82 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic fixup

455 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
456 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
457 port->fun_prefix anymore (may change later),
458 (genFunction, genEndFunction): do not store/restore local registers for
459 _main (this should take care the --main-return command line option in
461 (genOr): removed some legacy pic-port instructions,
462 * src/pic16/genarith.c (genAddLit): re-enabled old code because
463 performing operations with SFR's causes data to be written more than
464 once to each SFR. Perhaps SFRs should be handled in special cases...
465 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
467 * src/pic16/main.c (_process_pragma): stack bound checking did not take
468 into account for stack starting position,
469 (struct OPTIONS pic16_optionsTable): added command line argument
470 --extended or -y for Extended Instruction Support,
471 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
472 (deassignLRs): *** perhaps the most important change, old 'for' code
473 (commented out for reference), didn't account for some registers which
474 were left marked 'not free' after a pointer operation. The change
475 reduces register usage a lot in some cases

2750 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
2751 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
2752 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
2753 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
2754 always available in leading double underscore form. The C99 support is
2755 mostly missing, but it's a start.
2756 * support/regression/tests/bug-227710.c: fixed nonconforming use of
2757 reserved identifier "__data".
2759 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

2835 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2837 * device/lib/printf_large.c: removed inline assembly for portability and
2838 readability. Use printf_fast if speed or size are more important.
2839 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2840 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2842 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2844 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2845 prevent compiler warning
2847 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2849 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2850 moved to level 0 and declared as static. Also they are explicit
2851 placed in access bank. This was necessery because some times they
2852 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2853 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2854 optimizations. Currently only compare to unsigned char is implemented,
2855 * src/pic16/gen.c: added fReturnIdx array,
2856 * (struct resolvedIfx) is moved to gen.h and made public,
2857 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2858 * (aopForSym): added an optimization to directly store in stack of
2859 the operand of a SEND iCode,
2860 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2861 but as registers instead (AOP_REG) using the fReturnIdx array,
2862 * (pic16_freeAsmop): remove the freed register from the
2863 _G.sregsAlloc field,
2864 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2865 a compare of 'WREG',
2866 * (pic16_popGetTempRegCond): changed function prototype, now
2867 function takes also a bitVector argument v which holds the current
2868 set of registers that are allocated for stack access by aopForSym,
2869 registers allocated in aopForSym for accessing stack symbols are not
2870 any more part of the functions usedRegs field,
2871 * (genCall): some times aopOp is called for a stack variable to be
2872 send, aopForSym might perform the push, if this is true make sure
2873 that genCall doesn't push the variable twice by testing _G.resDirect,
2874 * (genFunction): changed testing for unspecified interrupt number
2875 from 256 to INTNO_UNSPEC,
2876 * modified selection scheme of frame pointer generation. Previously
2877 if function did use local registers a frame pointer was generated,
2878 now a frame pointer is generated only if function has arguments
2879 (that need PLUSW2 register access), or has stack arguments, or the
2880 compiler is not instructed to omit the frame pointer,
2881 * (genEndFunction): before restoring local registers that were saved
2882 in the function preamble, also restore the registers that *might*
2883 have been allocated for stack access,
2884 * (genRet): removed some old comments,
2885 * (genCmp, the active (RN's) version): added a call to the
2886 pic16_genCmp_special function to perform the compare with a more
2887 robust and optimized way,
2888 * (genInline): a feature has been added in inline code generation,
2889 which allows a wildcard variable substitution when writing inline
2890 assembly. Code is incomplete and experimental therefore undocumented,
2891 * (genCast): changed order of aopOp for result and right to allow
2892 aopForSym to directly load the result if possible,
2893 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2894 perform an optimized compare on some selected special occasions,
2895 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2896 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2897 generate an IVT any more,
2898 * src/pic16/main.c (pic16_optionsTable): added command line option
2900 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2901 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2903 * src/pic16/NOTES: Raphael Neider added in list of active developers
2904 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2905 jumptable_end to prevent bug #,
2906 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2907 inCond and outCond fields,
2908 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2909 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2910 turn off register spilling,
2911 * (packRegsForOneUse): synced with other ports' versions although it
2912 is not used currently,
2913 * (pic16_packRegisters): added an optimization while reading
2914 structure bitfields, some registers may be saved (malloc code is
2915 decreased by 80 bytes)
2917 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2919 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2920 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2921 this can be optimized more?
2923 2005-03-10 Raphael Neider <rneider AT web.de>
2925 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2926 genNearPointerGet): (hopefully) fixed access to bitfields via
2927 pointers (p->bitN = x; and x = p->bitN; failed)

2973 to keep the correct label reference count when adding/removing references
2974 to labels. A peephole file using this is appended to patch #1144962.

3561 Adding support for replacing ljmps with sjmps in jumptables
3562 generated for switch statements. For now you need to set the
3563 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3564 Now 4 algorithms for mcs51 jumptable generation are used:
3565 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3566 addresses loaded pc-relative for up to 112 cases and stack-pushing
3567 target addresses loaded with offset from dptr for up to 256 cases.

3597 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3599 * added libc directory. The current version of LibC contains string
3600 functions, ctype functions and macros and some functions of the
3601 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3602 be extensively tested in the future. Standard disclaimer here.
3603 Library is not automatically build yet. But one can build it by
3604 invoking 'make' inside the libc directory.
3605 * added ADC library under libio. Preliminary version yet.

3615 * (pic16_storeForReturn): optimized return of 0,
3616 * (genCmp): experimental code for new genCmp which uses PIC18's
3617 special compare&skip instructions. Initial tests fail some times
3618 with variables grater than 1 byte in size, so new code is disabled,
3619 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3621 * (genCast): began a fix to optimize the casting of a bit to another
3622 bit, now assigning a bitfield to another bitfield will fail, sorry,
3623 * src/pic16/main.c: disabled the use of lr-support feature,
3624 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

3631 and 1 for banking instruction,
3632 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3633 caused stop processing pCodes after a inline assembly block,
3634 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

3636 registers when it shouldn't,
3637 * src/pic16/ralloc.c (allocReg): add preliminary support for
3638 supporting a limited set of temporary registers,
3640 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3642 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,

3646 (genFunction): optimize RECEIVE iCodes in reentrant functions
3648 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6536 * src/SDCCast.c (addCast): added promotion to int
6537 (decorateType): updated call to upCast()
6538 * src/SDCCicode.c (geniCodeLeftShift): removed call to
6539 usualUnaryConversions()
6541 2004-01-26 Michael Hope <michaelh AT juju.net.nz>
6543 * support/regression/tests/literalop.c (mulWrapper): Added a
6544 wrapper to remove integer overflow warnings.
6546 * support/regression/tests/float_trans.c: Made work on host.
6548 * support/regression/ports/ucz80/spec.mk (UCZ80): Made detect the
6551 * support/regression/generate-cases.py (main): Changed from inline
6554 * doc/Makefile (install): Changed to depth first to get rid of
6555 missing directory install warning.
6557 * as/Makefile (install-doc): Made work on Mac.
6559 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
6561 * src/SDCCast.c: added an additional type flow in decorateType() of
6562 opposite direction, see feature request #860006; it's enabled at runtime
6563 by setting the environment variable SDCC_NEWTYPEFLOW
6564 * src/SDCCast.h: changed prototype of decorateType()
6565 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
6566 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
6567 'char' to 'int' can be omitted, if both operands are 'unsigned char';
6568 see feature request #877103
6569 * src/SDCCval.c: updated call of decorateType()
6570 (valBitwise): fixed bug #882876
6571 (valMinus): added promotion
6572 (valLogicAndOr): result is unsigned
6573 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
6574 * src/SDCCsymt.c (computeType),
6575 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
6576 must not cause an unsigned operation

6597 * src/pic/ralloc.h: applied patch from Slade Rich;
6598 added support for multiple code pages and multiple RAM banks on the
6599 PIC 14 port. The ASM files now no longer simply assume all the
6600 code / RAM are in the same page / bank. This means the linker can
6601 safely allocate code/RAM of separate ASM files to different pages/banks.
6602 * doc/sdccman.lyx: added Slade's tips
6603 * src/mcs51/peeph.def: fixed bug #880768

6615 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
6616 strtof is not part of C89 and isn't included with Mac OS X.
6618 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6620 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

6645 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6647 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6648 loaded with the linker search paths (-L arguments) and the libraries
6649 to be linked with the current source (-l arguments). Changes
6650 currently will affect only the pic16 port.
6651 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6652 include path the port specific paths and port specific libraries,
6653 * gplink command now contains the $3 argument,
6654 * src/pic16/device.h,
6655 * src/pic16/device.c,: structure PIC_device is made public and
6656 renamed to PIC16_device, the same for variable Pics which is renamed

6671 Documenting changes from previous commits.
6672 * configure.in (version 1.56),
6673 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6674 when generating output files to configure the pic16 library,
6675 but now I've commented it out, since gputils aren't installed in the
6676 SF compile farm, so library won't compile
6678 * device/lib/Makefile.in (version 1.56): initially I've added in
6679 target 'all' the prerequestive 'model-pic16' so it compiled the
6680 pic16 library, but now I've commented it out for the same reasons
6682 * added targets 'model-pic16' and 'objects-pic16' to compile the
6684 * added target 'port-specific-objects-pic16' to handle the
6685 generated libraries and copy them into the build/ directory
6686 * added target 'clean-intermediate-pic16' to clean intermediate
6687 files into pic16 directory
6688 * in target 'installdirs' added line to create directory pic16 in
6689 the installation path

6692 added lines to copy all header files to installation path,
6693 * in target 'installdirs' added line create directory for pic16
6694 headers in the installation path

6709 * src/z80/main.c (_parseOptions): fixed the portmode= command line
6710 option so that it actually works. Made it specific to the z80, since
6711 the gbz80 doesn't have these kinds of I/O ports.
6713 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6715 * device/include/z180.h,

6737 Mainly changes to support compilation of the device libraries
6738 * src/pic16/device.c: stack is allocated via symbol and not
6739 via literal number. The symbol is placed in the corresponding
6740 position of the data ram
6741 * (pic16_dump_section): relocatable and absolute uninitialized
6742 data are now emitted in sorted order to reduce section naming,
6743 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6744 weren't marked as being in the access bank,
6746 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6748 Added portion of GNU PIC Library under the directory
6749 device/include/pic16 and device/lib/pic16. These files
6750 contain the declarations of SFRs for the PIC18Fxx2 devices.
6751 The directory is initialized via configure from toplevel.

6781 all over. Telling LaTeX to be less strict with word spacing
6782 to better keep the right margin. Changed some notes about
6783 maintainance of the ports in section 3.2.1 - is it OK like this?
6785 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

6825 * src/pic16/peeph.def: all peepholes with movff are commented out,
6826 because there is a problem in the pcode peep optimizer,
6827 * src/pic16/ralloc.c: the register allocator can now reuse local

6966 Bug reported from Jesus Calvino-Fraga
6968 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6970 * sdcc.spec: updated
6971 * device/include/Makefile.in: don't install CVS directories

6979 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6981 PIC16 port related changes:
6982 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6983 added variable stackPos,
6985 * gen.c: genCall, assignResultValue: added support for
6986 pushing/retrieving function parameters to/from stack,
6987 genFunction,genEndFunction: setup stack frame for the
6989 genAddrOf: will be changed according to bug 863624
6991 * added files genutils.c and genutils.h which contain gen*
6992 debugged and optimised functions extracted from gen.c
6994 * glue.c: added variable 'externs' which holds extern symbols,
6995 pic16emitRegularMap: is modified to properly handle relocatable
6996 symbols under the new scheme,
6997 pic16createInterruptVect: is modified
6998 pic16printPublics: is modified to emit 'global' assembler directives,
6999 added pic16_printExterns to print extern symbols,
7000 pic16glue: initializes stack/frame pointer in the beginning of
7001 the assembly output. Temporary hack, will be corrected later,
7002 because gplink yet does not support stack and SDCC does not
7003 yet support a type of crt0.o object to create the final binary.
7005 * Removed many lines that contain 8051 legacy code.
7006 * The code is finally placed under a 'code' directive.
7007 * Added port specific options.
7009 * _process_pragma: simplified since now we do not need *special*
7010 include file to define SFR registers. But a separate header
7011 will be needed. This will be developed later.
7012 * _pic16_parseOptions: added, parses port specific options:
7013 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7014 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7015 --preplace-udata-with=
7017 * _pic16_setDefaultOptions: modified to initialize section names,
7018 but hack is temporarly out of order since it needs improvement.
7019 * _pic16_genAssemblerPreamble: configuration words are emitted by
7020 their address instead of their name. This part is incomplete and
7021 supports only the 18Fxx2 devices. Other devices will emit an error
7022 during assembly since they do not contain the same set of config
7024 * _pic16_genIVT: is modified,
7026 * pcode.c: added definitions for some hardware registers that are needed
7028 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7029 All PCI entries are updated. Now LFSR is supported.
7030 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7031 * added pic16_newpCodeOpLit2 to support instructions with
7032 two literal arguments
7033 * pic16_pCode2str: corrected code that emits assembler instructions
7034 with two literal operands and those that have an access bit modifier
7035 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7036 this fixes a bug which caused some labels to be lost, when an
7037 assembler directive was added, i.e. banksel,
7038 * pic16_FixRegisterBanking: improved logic that causes the insertion
7040 * InlineFunction: functions that are called once, are not any more
7041 inlined. This can be a port option in the future,
7043 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7045 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7046 hold the corresponding uninitialized symbols,
7047 * pic16_allocProcessorRegister: registers have explicit marked the
7049 * pic16_allocInternalRegister: registers are explicit marked as
7051 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7052 processing list, so bit registers were lost,
7055 * ralloc.h: added field 'accessBank' and original symbol operand
7056 in register definition,
7057 * removed the field isMapped from register definition,
7059 ** Several functions have been removed from various sources:
7060 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7061 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7062 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7063 pic16_assignRelocatableRegisters
7065 ** others have been introduced:
7066 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7067 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7069 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7071 * support/scripts/inc2h.pl: changed definition of BIT_AT
7072 to emit 'sbit at' instead of 'bit at'. This was a request.
7074 PIC16 port related preliminary changes:
7075 * gen.c: prefixed function popRegFromString with
7076 pic16_ and all references to it corrected
7077 * pcode.c: all pic16_pc_* hardware registers prefixed
7078 with underscore (_),
7079 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7080 * ralloc.c: newReg(): when register is REG_SFR then
7081 set address to rIdx,
7082 pic16_allocProcessorRegister(): marks register wasUsed=0
7083 pic16_writeUsedRegs(): added a call to assign processor
7084 registers via pic16_assignFixedRegisters
7086 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7088 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7089 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7090 variables in unused register banks. Also the SSEG is placed
7091 wherever there is enough space for it, and IDATA can be anywhere
7092 in internal RAM. For now compile using -Wl-Y[stack_size].
7093 The mem file is different for this option as well, since it
7094 makes no sense of talking about DSEG lenght.
7096 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7098 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7099 in certain cases, e.g. when ROM assignment, patch provided
7100 from Albert den Haan.

7343 * src/SDCCast.c (decorateType): disabled a transformation I added in
7344 revision 1.188 (access to fields of a structure at an absolute address);
7345 it breaks with bitfields, extern declarations, and gcse analysis.
7346 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7347 could be assigned through a pointer, so don't complain.
7348 * src/SDCCast.c (astErrors),

7455 xdata initialization slightly shorter
7457 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8107 copied from genNearPointerSet()
8108 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8109 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

8125 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8126 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8127 type for bits was changed. It resulted in bit variables becoming
8128 global, which is not permitted in PIC 14 assembly output.
8130 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8132 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8143 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8145 A few small changes that speed up the peephole optimizer.
8149 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8151 Try to make the peephole optimizer smarter by maintaining
8152 an association between the assembly source code and the
8153 iCodes that originated them. Put this information to use
8154 with a new peephole rule condition "notVolatile" so that
8155 the rules can be aggressive yet still safe.
8160 * src/mcs51/peeph.def
8162 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8166 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8167 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8168 if the left or right operand symbols have the accuse flag set.
8170 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8172 Changed the type of the result of the ! (NOT) operator to char;
8173 previously it returned the same type as the source. This allows
8174 us to eliminate all the genFloatNot functions (all of its target
8175 implementations were very buggy) since !float can use the same
8178 * src/SDCCicode.c (ast2iCode): ! returns char
8179 * src/mcs51/gen.c (genNot, genNotFloat),
8180 * src/ds390/gen.c (genNot, genNotFloat),
8181 * src/z80/gen.c (genNot, genNotFloat),
8182 * src/pic/gen.c (genNot, genNotFloat),
8183 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
8185 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
8187 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8188 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8189 during interrupts. Ensure WSAVE is located at a shared bank address.
8190 2. Fixed page selection in some places
8191 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8192 the registers name strings.
8193 4. Fixed "signed / unsigned compare" compiler warnings.
8194 5. The PIC port manages its own allocation of the general purpose
8195 registers, but makes no attempt to reuse them. As a result when
8196 compiling it soon runs out of general purpose registers. Some
8197 additional code was added to the files pcode.c and device.c to walk
8198 through the function call tree and rename the registers so that they
8208 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8209 genPlus() & genMinus() when the result is the same as left or right

8215 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8217 Made bitfield a distinct type from bit so that bitfields
8218 convert as per ANSI C and bits retain their traditional
8219 boolean style behaviour. Implemented bitfield support in
8227 * src/ds390/gen.c: bit v bitfield split
8228 * src/z80/gen.c: New support for bitfields
8229 * support/regression/tests/bitfields.c: reenabled z80,
8232 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8234 Rules 246.x, 247.x relate to bitfields, the others speed up
8235 access to xdata mapped I/O devices.
8237 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8239 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8241 Cleaned up genPackBits and genUnpackBits and added two helper
8242 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8243 for literal assignments in genPackBits (thanks to Frieder for
8249 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8251 Fixed bug #748310 (pointer to function type mishandled when the
8252 function name is omitted). Also fixed a SIGSEGV when a function
8253 attribute (reentrant, etc) is used on a non-function or on a
8254 function but misplaced before the parameter list.
8256 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8258 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8259 * support/Util/SDCCerr.h,
8260 * support/Util/SDCCerr.c: Added func attr misuse error msg
8262 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
8264 Fixed bug #787649 by anonymous
8265 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr

8281 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8283 Made the constant following the "interrupt" keyword optional. If
8284 omitted, the function will not automatically be given an entry
8285 in the interrupt vector table (similar to #pragma NOIV, but
8286 less syntacticly kludgy). The interrupt number is also now
8287 range checked. Also fixed a bug in the high order bit example
8294 * support/Util/SDCCerr.c
8295 * support/Util/SDCCerr.h
8298 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

8301 * src/SDCCicode.c (operandOperation): rewritten some ops
8302 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8303 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8305 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8306 be re-activated by defining REDUCE_LITERALS)
8307 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8308 unsigned, but are signed by default
8309 * src/SDCCval.c (constVal): rearranged
8310 * src/SDCCval.c (valMod): preliminary fix
8311 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8353 constants are unsigned; added recognition of "u" flag for unsigned
8354 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
8355 * src/SDCCval.c (valDiv, valMod): fixed signdness
8356 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
8357 signedness of modulo, left and right shift

8763 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
8764 the regression tests I'm not brave enough to enable 245.b, 245.c
8765 * doc/sdccman.lyx: added latex preamble for hyperref package.
8766 Using pdflatex this will give you a hyperlinked pdf file with
8767 bookmarks. (prepend '%' before /usepackage if this breaks something)

8805 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
8807 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
8808 it can be defined with CFLAGS when running configure
8809 * src/SDCCmain.c: fixed compiling + linking with object files
8811 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

8814 added --disable-pic16-port
8815 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
8816 * src/SDCCmain.c: linkOptions is changed to set *,
8817 added if/endif conditional macros to remove options help
8818 messages from optionsTable when a port is not configured, added
8819 support for the PIc16 port in the ports table, when executing
8820 the compiler with no port specified on command line, a default
8821 port is selected with the new macro DEFAULT_PORT which is
8822 defined in port.h, in setDefaultOptions() linkOptions is removed
8823 from initialization assignment, since now it is a set,
8824 parseCmdLine uses setParseWithComma for linkOptions, in
8825 linkEdit() linkOptions are accessed with new function indexSet()
8826 which returns the i'th item of a set variable. See SDCCset.c, in
8827 linkEdit() when calling buildCmdLine(), added linkOptions as
8828 last argument. Now users can pass arguments to gplink via the
8829 -Wl option, main() uses pic16glue() to glue up pic16 programs

8841 * src/pic16/glue.c: commented out some error producing lines
8842 * src/pic16/main.c: __config directives are commented out to stop
8843 gpasm complaining and test the linkage with gplink, _linkCmd and
8844 _asmCmd changed to be more gplink and gpasm friendly
8845 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8846 produced an error when parsed, peep rule 12 is added to utilize
8847 movff, but it is commented out since the pCode does not support
8848 yet a command with 2 address arguments
8850 2003-05-18 <johan AT balder>
8852 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
8853 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8877 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
8879 2003-05-11 Borut Razem <borut.razem AT siol.net>
8881 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
8882 the path of bin directory, so that PATH is the only env. variable, which has to be set
8883 in case of standard installation.
8884 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

9954 Changes to aslink (All the changes are marked with 'JCF'):
9956 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9959 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9960 area BSEG. Also moves, if possible, the DATA area down into the internal
9961 ram so more space is available.
9963 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9966 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9967 not bytes. Function summary() which creates a memory usage summary
9968 file with extension .mem. Reports of overlaping stack and small stack
9969 size. If the space for the stack is less than 16 bytes aslink trows a
9972 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9973 the 8051. Option 'y' for memory summary output file.
9975 Changes to sdcc (All the changes are marked with 'JCF'):
9977 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9979 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9980 overlaying area for it (uses RegBankUsed[4]).
9982 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9983 bank zero as used by default. By default aslink locates the stack
9984 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9985 the creation of the .mem file. Delegates the allocation of data area
9986 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9987 the begining of the stack area to aslink.
9989 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9990 glue() in SDCCglue.c creates an area for it.
9992 2002-09-03 Borut Razem <borut.razem AT siol.net>
9993 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9994 sdcc/src/pic/glue.c:
9995 introduced atexit() handler for teporay files removal in case of
9996 errors, assertions, ...
9998 2002-08-29 Borut Razem <borut.razem AT siol.net>
9999 * sdcc/support/cpp2/auto-host_vc_in.h:
10000 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10001 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10002 Maybe there is a similar problem with BORLANDC? It should be checked!
10004 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10005 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10006 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10007 was not executed, and the compiler (cl) launched a warning:
10008 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10010 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10011 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10013 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10014 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10016 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10017 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10018 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10019 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10020 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10021 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10022 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10023 - added Release configuration in VS projects
10024 - review of compiler an linker options
10025 - VC .exe files are generated in bin_vc directory, not to interfere
10026 with binaries generated from other projects (cygwin, mingw, bcc ...)
10028 * sdcc/src/yacc.dsp: added
10030 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10031 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10032 and insert the version number definitions from .version
10034 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10036 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10037 added - genarate auto-host.h using auto-host_vc_in.h as template
10040 removed from CVS, generated automatically
10042 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10043 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10045 2002-08-11 Borut Razem <borut.razem AT siol.net>
10046 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10048 2002-08-10 Borut Razem <borut.razem AT siol.net>
10049 * src/SDCCmain.c (main):
10050 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10051 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10052 The consequence was that some temporary files were not removed.
10055 unification of code in functions tempfilename() and tempfile():
10056 function tempnam() is defined in Visual Studio 6.0 and .NET
10058 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10060 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10061 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10062 - removed compiler command line option /WX: Treats all warnings as errors
10063 - update a list of source files, included into the project
10065 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10066 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10067 changed project type to Generic Project so that can be correcly converted to VS.NET project
10069 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10071 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10073 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10075 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10076 added return 0 statements after assert() to make compiler happy
10078 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10079 added newline in the def file to keep MSC compiler satisfied
10081 * sdcc/src/z80/gen.c:
10082 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10083 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10084 - solved MSC error in function aopDump()
10086 * sdcc_vc.h: define PREFIX as "\\sdcc"
10088 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10089 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10128 2002-03-28 Johan Knol <johan AT balder>
10130 * src/SDCCval.c: fixed bug #532436
10132 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10134 Added "char *Processor" field to the port structure.
10137 Added -p option. Allows port dependent processor to be specified.
10140 Initialized the new field char *Processor field to NULL in all ports
10143 Compiler generated registers for interrupt context saving
10144 were not getting allocated.
10146 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10149 Fixed left shift. Will promote the left side of a left shift
10150 if a) left shifting more than size of operand or b) when assigned
10151 to something size > size of left side

10261 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10263 * sdcc/src/SDCCloop.c:
10264 Previous fix was not good. basic blocks that have "break" or "return" are
10265 not really partof a loop , but live ranges used in these blocks should
10266 be live thru the entire loop, so set partOfLoop but don't add them to
10269 2002-02-21 <johan AT FRIJA>
10271 * src/SDCCcse.c: fixed bug #514308
10273 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
