34 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
36 Enabled VPATH feature: changed nearly all Makefiles (149 files).
37 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
39 One basic decision: e.g. src/clean.mk includes further files. In order
40 to make this work there are two solutions:
41 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
42 run configure on them. This way they can use
43 'include $(srcdir)/port-clean.mk'
44 - always include clean.mk by the Makefile at the same level. To avoid
45 that `make clean` tries to include and build Makefile.dep the
46 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
47 implemented, because now even `make uninstall` doesn't create
48 Makefile.in. clean.mk could be eliminated by pasting it in
51 * debugger/mcs51/Makefile.in: build own objects from library sources
52 (SLIB, SDCC) in current directory
54 * configure, configure.in: renamed --disable-device-lib-build in
55 --disable-device-lib; added --enable-doc, the required tools are
56 searched by configure; added result message; the toolchain for the
57 belonging ports are now only built, if the port is enabled.
59 * support/regression/*: all output is written in directory gen, because
60 the fwk and ports directories don't livet in the build tree using vpath
62 * doc/sdccman.lyx: renamed --disable-device-lib-build to
63 --disable-device-lib, added --enable-doc, added section VPATH
65 * sim/ucsim/configure.in,
66 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
67 z80 are enabled by default
69 2006-04-24 Raphael Neider <rneider AT web.de>
71 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments to
72 config word, "pic14_"-prefixed some extern functions

74 config word has been found
75 * src/pic/device.h: added prototypes
76 * src/pic/pcode.c: added "pic14_"-prefix where needed

385 allocating functions mark all registers as free. This eliminates some
386 side effects resulting from peephole parser done earlier in the backbone

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

2745 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
2746 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
2747 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
2748 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
2749 always available in leading double underscore form. The C99 support is
2750 mostly missing, but it's a start.
2751 * support/regression/tests/bug-227710.c: fixed nonconforming use of
2752 reserved identifier "__data".

2830 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2832 * device/lib/printf_large.c: removed inline assembly for portability and
2833 readability. Use printf_fast if speed or size are more important.
2834 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2835 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2837 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2839 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2840 prevent compiler warning
2842 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2844 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2845 moved to level 0 and declared as static. Also they are explicit
2846 placed in access bank. This was necessery because some times they
2847 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2848 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2849 optimizations. Currently only compare to unsigned char is implemented,
2850 * src/pic16/gen.c: added fReturnIdx array,
2851 * (struct resolvedIfx) is moved to gen.h and made public,
2852 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2853 * (aopForSym): added an optimization to directly store in stack of
2854 the operand of a SEND iCode,
2855 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2856 but as registers instead (AOP_REG) using the fReturnIdx array,
2857 * (pic16_freeAsmop): remove the freed register from the
2858 _G.sregsAlloc field,
2859 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2860 a compare of 'WREG',
2861 * (pic16_popGetTempRegCond): changed function prototype, now
2862 function takes also a bitVector argument v which holds the current
2863 set of registers that are allocated for stack access by aopForSym,
2864 registers allocated in aopForSym for accessing stack symbols are not
2865 any more part of the functions usedRegs field,
2866 * (genCall): some times aopOp is called for a stack variable to be
2867 send, aopForSym might perform the push, if this is true make sure
2868 that genCall doesn't push the variable twice by testing _G.resDirect,
2869 * (genFunction): changed testing for unspecified interrupt number
2870 from 256 to INTNO_UNSPEC,
2871 * modified selection scheme of frame pointer generation. Previously
2872 if function did use local registers a frame pointer was generated,
2873 now a frame pointer is generated only if function has arguments
2874 (that need PLUSW2 register access), or has stack arguments, or the
2875 compiler is not instructed to omit the frame pointer,
2876 * (genEndFunction): before restoring local registers that were saved
2877 in the function preamble, also restore the registers that *might*
2878 have been allocated for stack access,
2879 * (genRet): removed some old comments,
2880 * (genCmp, the active (RN's) version): added a call to the
2881 pic16_genCmp_special function to perform the compare with a more
2882 robust and optimized way,
2883 * (genInline): a feature has been added in inline code generation,
2884 which allows a wildcard variable substitution when writing inline
2885 assembly. Code is incomplete and experimental therefore undocumented,
2886 * (genCast): changed order of aopOp for result and right to allow
2887 aopForSym to directly load the result if possible,
2888 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2889 perform an optimized compare on some selected special occasions,
2890 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2891 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2892 generate an IVT any more,
2893 * src/pic16/main.c (pic16_optionsTable): added command line option
2895 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2896 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2898 * src/pic16/NOTES: Raphael Neider added in list of active developers
2899 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2900 jumptable_end to prevent bug #,
2901 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2902 inCond and outCond fields,
2903 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2904 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2905 turn off register spilling,
2906 * (packRegsForOneUse): synced with other ports' versions although it
2907 is not used currently,
2908 * (pic16_packRegisters): added an optimization while reading
2909 structure bitfields, some registers may be saved (malloc code is
2910 decreased by 80 bytes)
2912 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2914 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2915 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2916 this can be optimized more?
2918 2005-03-10 Raphael Neider <rneider AT web.de>
2920 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2921 genNearPointerGet): (hopefully) fixed access to bitfields via
2922 pointers (p->bitN = x; and x = p->bitN; failed)
2924 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3556 Adding support for replacing ljmps with sjmps in jumptables
3557 generated for switch statements. For now you need to set the
3558 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3559 Now 4 algorithms for mcs51 jumptable generation are used:
3560 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3561 addresses loaded pc-relative for up to 112 cases and stack-pushing
3562 target addresses loaded with offset from dptr for up to 256 cases.

3592 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3594 * added libc directory. The current version of LibC contains string
3595 functions, ctype functions and macros and some functions of the
3596 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3597 be extensively tested in the future. Standard disclaimer here.
3598 Library is not automatically build yet. But one can build it by
3599 invoking 'make' inside the libc directory.
3600 * added ADC library under libio. Preliminary version yet.

3610 * (pic16_storeForReturn): optimized return of 0,
3611 * (genCmp): experimental code for new genCmp which uses PIC18's
3612 special compare&skip instructions. Initial tests fail some times
3613 with variables grater than 1 byte in size, so new code is disabled,
3614 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3616 * (genCast): began a fix to optimize the casting of a bit to another
3617 bit, now assigning a bitfield to another bitfield will fail, sorry,
3618 * src/pic16/main.c: disabled the use of lr-support feature,
3619 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

3626 and 1 for banking instruction,
3627 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3628 caused stop processing pCodes after a inline assembly block,
3629 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

3631 registers when it shouldn't,
3632 * src/pic16/ralloc.c (allocReg): add preliminary support for
3633 supporting a limited set of temporary registers,
3635 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6543 * support/regression/ports/ucz80/spec.mk (UCZ80): Made detect the
6546 * support/regression/generate-cases.py (main): Changed from inline
6549 * doc/Makefile (install): Changed to depth first to get rid of
6550 missing directory install warning.
6552 * as/Makefile (install-doc): Made work on Mac.
6554 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
6556 * src/SDCCast.c: added an additional type flow in decorateType() of
6557 opposite direction, see feature request #860006; it's enabled at runtime
6558 by setting the environment variable SDCC_NEWTYPEFLOW
6559 * src/SDCCast.h: changed prototype of decorateType()
6560 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
6561 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
6562 'char' to 'int' can be omitted, if both operands are 'unsigned char';
6563 see feature request #877103
6564 * src/SDCCval.c: updated call of decorateType()
6565 (valBitwise): fixed bug #882876
6566 (valMinus): added promotion
6567 (valLogicAndOr): result is unsigned
6568 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
6569 * src/SDCCsymt.c (computeType),
6570 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
6571 must not cause an unsigned operation
6572 * src/pic/glue (pic14emitRegularMap),
6573 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
6575 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>

6592 * src/pic/ralloc.h: applied patch from Slade Rich;
6593 added support for multiple code pages and multiple RAM banks on the
6594 PIC 14 port. The ASM files now no longer simply assume all the
6595 code / RAM are in the same page / bank. This means the linker can
6596 safely allocate code/RAM of separate ASM files to different pages/banks.
6597 * doc/sdccman.lyx: added Slade's tips
6598 * src/mcs51/peeph.def: fixed bug #880768

6607 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
6610 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
6611 strtof is not part of C89 and isn't included with Mac OS X.
6613 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6615 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

6640 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6642 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6643 loaded with the linker search paths (-L arguments) and the libraries
6644 to be linked with the current source (-l arguments). Changes
6645 currently will affect only the pic16 port.
6646 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6647 include path the port specific paths and port specific libraries,
6648 * gplink command now contains the $3 argument,
6649 * src/pic16/device.h,
6650 * src/pic16/device.c,: structure PIC_device is made public and
6651 renamed to PIC16_device, the same for variable Pics which is renamed

6666 Documenting changes from previous commits.
6667 * configure.in (version 1.56),
6668 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6669 when generating output files to configure the pic16 library,
6670 but now I've commented it out, since gputils aren't installed in the
6671 SF compile farm, so library won't compile
6673 * device/lib/Makefile.in (version 1.56): initially I've added in
6674 target 'all' the prerequestive 'model-pic16' so it compiled the
6675 pic16 library, but now I've commented it out for the same reasons
6677 * added targets 'model-pic16' and 'objects-pic16' to compile the
6679 * added target 'port-specific-objects-pic16' to handle the
6680 generated libraries and copy them into the build/ directory
6681 * added target 'clean-intermediate-pic16' to clean intermediate
6682 files into pic16 directory
6683 * in target 'installdirs' added line to create directory pic16 in
6684 the installation path
6686 * device/include/Makefile.in (version 1.11): in target 'install'
6687 added lines to copy all header files to installation path,
6688 * in target 'installdirs' added line create directory for pic16
6689 headers in the installation path

6704 * src/z80/main.c (_parseOptions): fixed the portmode= command line
6705 option so that it actually works. Made it specific to the z80, since
6706 the gbz80 doesn't have these kinds of I/O ports.
6708 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6710 * device/include/z180.h,

6732 Mainly changes to support compilation of the device libraries
6733 * src/pic16/device.c: stack is allocated via symbol and not
6734 via literal number. The symbol is placed in the corresponding
6735 position of the data ram
6736 * (pic16_dump_section): relocatable and absolute uninitialized
6737 data are now emitted in sorted order to reduce section naming,
6738 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6739 weren't marked as being in the access bank,
6741 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6743 Added portion of GNU PIC Library under the directory
6744 device/include/pic16 and device/lib/pic16. These files
6745 contain the declarations of SFRs for the PIC18Fxx2 devices.
6746 The directory is initialized via configure from toplevel.
6748 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
6750 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

6776 all over. Telling LaTeX to be less strict with word spacing
6777 to better keep the right margin. Changed some notes about
6778 maintainance of the ports in section 3.2.1 - is it OK like this?
6780 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

6818 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
6820 * src/pic16/peeph.def: all peepholes with movff are commented out,
6821 because there is a problem in the pcode peep optimizer,
6822 * src/pic16/ralloc.c: the register allocator can now reuse local

6961 Bug reported from Jesus Calvino-Fraga
6963 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6965 * sdcc.spec: updated
6966 * device/include/Makefile.in: don't install CVS directories

6969 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6970 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6971 * src/ds390/gen.c (genRightShift): fixed bug #870788
6972 * src/SDCCast.c (decorateType): fixed bug #870781
6974 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6976 PIC16 port related changes:
6977 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6978 added variable stackPos,
6980 * gen.c: genCall, assignResultValue: added support for
6981 pushing/retrieving function parameters to/from stack,
6982 genFunction,genEndFunction: setup stack frame for the
6984 genAddrOf: will be changed according to bug 863624
6986 * added files genutils.c and genutils.h which contain gen*
6987 debugged and optimised functions extracted from gen.c
6989 * glue.c: added variable 'externs' which holds extern symbols,
6990 pic16emitRegularMap: is modified to properly handle relocatable
6991 symbols under the new scheme,
6992 pic16createInterruptVect: is modified
6993 pic16printPublics: is modified to emit 'global' assembler directives,
6994 added pic16_printExterns to print extern symbols,
6995 pic16glue: initializes stack/frame pointer in the beginning of
6996 the assembly output. Temporary hack, will be corrected later,
6997 because gplink yet does not support stack and SDCC does not
6998 yet support a type of crt0.o object to create the final binary.
7000 * Removed many lines that contain 8051 legacy code.
7001 * The code is finally placed under a 'code' directive.
7002 * Added port specific options.
7004 * _process_pragma: simplified since now we do not need *special*
7005 include file to define SFR registers. But a separate header
7006 will be needed. This will be developed later.
7007 * _pic16_parseOptions: added, parses port specific options:
7008 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7009 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7010 --preplace-udata-with=
7012 * _pic16_setDefaultOptions: modified to initialize section names,
7013 but hack is temporarly out of order since it needs improvement.
7014 * _pic16_genAssemblerPreamble: configuration words are emitted by
7015 their address instead of their name. This part is incomplete and
7016 supports only the 18Fxx2 devices. Other devices will emit an error
7017 during assembly since they do not contain the same set of config
7019 * _pic16_genIVT: is modified,
7021 * pcode.c: added definitions for some hardware registers that are needed
7023 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7024 All PCI entries are updated. Now LFSR is supported.
7025 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7026 * added pic16_newpCodeOpLit2 to support instructions with
7027 two literal arguments
7028 * pic16_pCode2str: corrected code that emits assembler instructions
7029 with two literal operands and those that have an access bit modifier
7030 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7031 this fixes a bug which caused some labels to be lost, when an
7032 assembler directive was added, i.e. banksel,
7033 * pic16_FixRegisterBanking: improved logic that causes the insertion
7035 * InlineFunction: functions that are called once, are not any more
7036 inlined. This can be a port option in the future,
7038 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7040 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7041 hold the corresponding uninitialized symbols,
7042 * pic16_allocProcessorRegister: registers have explicit marked the
7044 * pic16_allocInternalRegister: registers are explicit marked as
7046 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7047 processing list, so bit registers were lost,
7050 * ralloc.h: added field 'accessBank' and original symbol operand
7051 in register definition,
7052 * removed the field isMapped from register definition,
7054 ** Several functions have been removed from various sources:
7055 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7056 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7057 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7058 pic16_assignRelocatableRegisters
7060 ** others have been introduced:
7061 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7062 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7064 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7066 * support/scripts/inc2h.pl: changed definition of BIT_AT
7067 to emit 'sbit at' instead of 'bit at'. This was a request.
7069 PIC16 port related preliminary changes:
7070 * gen.c: prefixed function popRegFromString with
7071 pic16_ and all references to it corrected
7072 * pcode.c: all pic16_pc_* hardware registers prefixed
7073 with underscore (_),
7074 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7075 * ralloc.c: newReg(): when register is REG_SFR then
7076 set address to rIdx,
7077 pic16_allocProcessorRegister(): marks register wasUsed=0
7078 pic16_writeUsedRegs(): added a call to assign processor
7079 registers via pic16_assignFixedRegisters
7081 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7083 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7084 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7085 variables in unused register banks. Also the SSEG is placed
7086 wherever there is enough space for it, and IDATA can be anywhere
7087 in internal RAM. For now compile using -Wl-Y[stack_size].
7088 The mem file is different for this option as well, since it
7089 makes no sense of talking about DSEG lenght.
7091 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7093 * src/SDCClrange.c: fixed bug 869095 that caused segfault

7338 * src/SDCCast.c (decorateType): disabled a transformation I added in
7339 revision 1.188 (access to fields of a structure at an absolute address);
7340 it breaks with bitfields, extern declarations, and gcse analysis.
7341 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7342 could be assigned through a pointer, so don't complain.

7450 xdata initialization slightly shorter
7452 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8099 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8100 fetching of the pointer
8101 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8102 copied from genNearPointerSet()
8103 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8104 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

8118 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8120 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8121 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8122 type for bits was changed. It resulted in bit variables becoming
8123 global, which is not permitted in PIC 14 assembly output.
8125 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8127 * doc/sdccman.lyx: various additions and updates. Rearranged sections
8129 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8131 Z80 and MCS51 linkers complaint if a public symbol is defined

8140 A few small changes that speed up the peephole optimizer.
8144 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8146 Try to make the peephole optimizer smarter by maintaining
8147 an association between the assembly source code and the
8148 iCodes that originated them. Put this information to use
8149 with a new peephole rule condition "notVolatile" so that
8150 the rules can be aggressive yet still safe.
8155 * src/mcs51/peeph.def
8157 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8161 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8162 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8163 if the left or right operand symbols have the accuse flag set.
8165 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8167 Changed the type of the result of the ! (NOT) operator to char;
8168 previously it returned the same type as the source. This allows
8169 us to eliminate all the genFloatNot functions (all of its target
8170 implementations were very buggy) since !float can use the same
8173 * src/SDCCicode.c (ast2iCode): ! returns char
8174 * src/mcs51/gen.c (genNot, genNotFloat),
8175 * src/ds390/gen.c (genNot, genNotFloat),
8176 * src/z80/gen.c (genNot, genNotFloat),
8177 * src/pic/gen.c (genNot, genNotFloat),
8178 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
8180 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
8182 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8183 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8184 during interrupts. Ensure WSAVE is located at a shared bank address.
8185 2. Fixed page selection in some places
8186 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8187 the registers name strings.
8188 4. Fixed "signed / unsigned compare" compiler warnings.
8189 5. The PIC port manages its own allocation of the general purpose
8190 registers, but makes no attempt to reuse them. As a result when
8191 compiling it soon runs out of general purpose registers. Some
8192 additional code was added to the files pcode.c and device.c to walk
8193 through the function call tree and rename the registers so that they
8203 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8204 genPlus() & genMinus() when the result is the same as left or right

8210 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8212 Made bitfield a distinct type from bit so that bitfields
8213 convert as per ANSI C and bits retain their traditional
8214 boolean style behaviour. Implemented bitfield support in
8222 * src/ds390/gen.c: bit v bitfield split
8223 * src/z80/gen.c: New support for bitfields
8224 * support/regression/tests/bitfields.c: reenabled z80,
8227 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8229 Rules 246.x, 247.x relate to bitfields, the others speed up
8230 access to xdata mapped I/O devices.
8232 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8234 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8236 Cleaned up genPackBits and genUnpackBits and added two helper
8237 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8238 for literal assignments in genPackBits (thanks to Frieder for
8244 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8246 Fixed bug #748310 (pointer to function type mishandled when the
8247 function name is omitted). Also fixed a SIGSEGV when a function
8248 attribute (reentrant, etc) is used on a non-function or on a
8249 function but misplaced before the parameter list.
8251 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8253 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

8276 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8278 Made the constant following the "interrupt" keyword optional. If
8279 omitted, the function will not automatically be given an entry
8280 in the interrupt vector table (similar to #pragma NOIV, but
8281 less syntacticly kludgy). The interrupt number is also now
8282 range checked. Also fixed a bug in the high order bit example
8289 * support/Util/SDCCerr.c
8290 * support/Util/SDCCerr.h
8293 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

8296 * src/SDCCicode.c (operandOperation): rewritten some ops
8297 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8298 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8300 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8301 be re-activated by defining REDUCE_LITERALS)
8302 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8303 unsigned, but are signed by default
8304 * src/SDCCval.c (constVal): rearranged
8305 * src/SDCCval.c (valMod): preliminary fix
8306 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8758 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
8759 the regression tests I'm not brave enough to enable 245.b, 245.c

8761 Using pdflatex this will give you a hyperlinked pdf file with
8762 bookmarks. (prepend '%' before /usepackage if this breaks something)

8803 it can be defined with CFLAGS when running configure
8804 * src/SDCCmain.c: fixed compiling + linking with object files
8806 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

8809 added --disable-pic16-port
8810 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
8811 * src/SDCCmain.c: linkOptions is changed to set *,
8812 added if/endif conditional macros to remove options help
8813 messages from optionsTable when a port is not configured, added
8814 support for the PIc16 port in the ports table, when executing
8815 the compiler with no port specified on command line, a default
8816 port is selected with the new macro DEFAULT_PORT which is
8817 defined in port.h, in setDefaultOptions() linkOptions is removed
8818 from initialization assignment, since now it is a set,
8819 parseCmdLine uses setParseWithComma for linkOptions, in
8820 linkEdit() linkOptions are accessed with new function indexSet()
8821 which returns the i'th item of a set variable. See SDCCset.c, in
8822 linkEdit() when calling buildCmdLine(), added linkOptions as
8823 last argument. Now users can pass arguments to gplink via the
8824 -Wl option, main() uses pic16glue() to glue up pic16 programs

8836 * src/pic16/glue.c: commented out some error producing lines
8837 * src/pic16/main.c: __config directives are commented out to stop
8838 gpasm complaining and test the linkage with gplink, _linkCmd and
8839 _asmCmd changed to be more gplink and gpasm friendly
8840 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8841 produced an error when parsed, peep rule 12 is added to utilize
8842 movff, but it is commented out since the pCode does not support
8843 yet a command with 2 address arguments
8845 2003-05-18 <johan AT balder>
8847 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
8848 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8874 2003-05-11 Borut Razem <borut.razem AT siol.net>
8876 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
8877 the path of bin directory, so that PATH is the only env. variable, which has to be set
8878 in case of standard installation.
8879 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

9961 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9962 not bytes. Function summary() which creates a memory usage summary
9963 file with extension .mem. Reports of overlaping stack and small stack
9964 size. If the space for the stack is less than 16 bytes aslink trows a
9967 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9968 the 8051. Option 'y' for memory summary output file.
9970 Changes to sdcc (All the changes are marked with 'JCF'):
9972 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9974 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9975 overlaying area for it (uses RegBankUsed[4]).
9977 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9978 bank zero as used by default. By default aslink locates the stack
9979 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9980 the creation of the .mem file. Delegates the allocation of data area
9981 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9982 the begining of the stack area to aslink.
9984 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9985 glue() in SDCCglue.c creates an area for it.
9987 2002-09-03 Borut Razem <borut.razem AT siol.net>
9988 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9989 sdcc/src/pic/glue.c:
9990 introduced atexit() handler for teporay files removal in case of
9991 errors, assertions, ...
9993 2002-08-29 Borut Razem <borut.razem AT siol.net>
9994 * sdcc/support/cpp2/auto-host_vc_in.h:
9995 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9996 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9997 Maybe there is a similar problem with BORLANDC? It should be checked!
9999 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10000 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10001 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10002 was not executed, and the compiler (cl) launched a warning:
10003 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10005 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10006 * src/SDCCglue.c (printIvalArray): iterative calculation of array length

10009 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10011 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10012 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10013 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10014 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10015 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10016 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10017 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10018 - added Release configuration in VS projects
10019 - review of compiler an linker options
10020 - VC .exe files are generated in bin_vc directory, not to interfere
10021 with binaries generated from other projects (cygwin, mingw, bcc ...)
10023 * sdcc/src/yacc.dsp: added
10025 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10026 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10027 and insert the version number definitions from .version
10029 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10031 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10032 added - genarate auto-host.h using auto-host_vc_in.h as template
10035 removed from CVS, generated automatically
10037 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10038 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10040 2002-08-11 Borut Razem <borut.razem AT siol.net>
10041 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10043 2002-08-10 Borut Razem <borut.razem AT siol.net>
10044 * src/SDCCmain.c (main):
10045 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10046 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10047 The consequence was that some temporary files were not removed.
10050 unification of code in functions tempfilename() and tempfile():
10051 function tempnam() is defined in Visual Studio 6.0 and .NET
10053 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10055 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10056 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10057 - removed compiler command line option /WX: Treats all warnings as errors
10058 - update a list of source files, included into the project
10060 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10061 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10062 changed project type to Generic Project so that can be correcly converted to VS.NET project
10064 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10066 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10068 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10070 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10071 added return 0 statements after assert() to make compiler happy
10073 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10074 added newline in the def file to keep MSC compiler satisfied
10076 * sdcc/src/z80/gen.c:
10077 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10078 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10079 - solved MSC error in function aopDump()
10081 * sdcc_vc.h: define PREFIX as "\\sdcc"
10083 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10084 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10132 Added -p option. Allows port dependent processor to be specified.
10135 Initialized the new field char *Processor field to NULL in all ports
10138 Compiler generated registers for interrupt context saving
10139 were not getting allocated.
10141 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10144 Fixed left shift. Will promote the left side of a left shift
10145 if a) left shifting more than size of operand or b) when assigned

10256 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10258 * sdcc/src/SDCCloop.c:
10259 Previous fix was not good. basic blocks that have "break" or "return" are
10260 not really partof a loop , but live ranges used in these blocks should
10261 be live thru the entire loop, so set partOfLoop but don't add them to
10264 2002-02-21 <johan AT FRIJA>
10266 * src/SDCCcse.c: fixed bug #514308
10268 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
