30 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
32 Enabled VPATH feature: changed nearly all Makefiles (149 files).
33 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
35 One basic decision: e.g. src/clean.mk includes further files. In order
36 to make this work there are two solutions:
37 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
38 run configure on them. This way they can use
39 'include $(srcdir)/port-clean.mk'
40 - always include clean.mk by the Makefile at the same level. To avoid
41 that `make clean` tries to include and build Makefile.dep the
42 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
43 implemented, because now even `make uninstall` doesn't create
44 Makefile.in. clean.mk could be eliminated by pasting it in
47 * debugger/mcs51/Makefile.in: build own objects from library sources
48 (SLIB, SDCC) in current directory
50 * configure, configure.in: renamed --disable-device-lib-build in
51 --disable-device-lib; added --enable-doc, the required tools are
52 searched by configure; added result message; the toolchain for the
53 belonging ports are now only built, if the port is enabled.
55 * support/regression/*: all output is written in directory gen, because
56 the fwk and ports directories don't livet in the build tree using vpath
58 * doc/sdccman.lyx: renamed --disable-device-lib-build to
59 --disable-device-lib, added --enable-doc, added section VPATH
61 * sim/ucsim/configure.in,
62 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
63 z80 are enabled by default
65 2006-04-24 Raphael Neider <rneider AT web.de>
67 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments to

70 config word has been found
71 * src/pic/device.h: added prototypes

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

453 * src/pic16/genarith.c (genAddLit): re-enabled old code because
454 performing operations with SFR's causes data to be written more than
455 once to each SFR. Perhaps SFRs should be handled in special cases...
456 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
458 * src/pic16/main.c (_process_pragma): stack bound checking did not take
459 into account for stack starting position,
460 (struct OPTIONS pic16_optionsTable): added command line argument
461 --extended or -y for Extended Instruction Support,
462 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
463 (deassignLRs): *** perhaps the most important change, old 'for' code
464 (commented out for reference), didn't account for some registers which
465 were left marked 'not free' after a pointer operation. The change
466 reduces register usage a lot in some cases

2741 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
2742 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
2743 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
2744 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
2745 always available in leading double underscore form. The C99 support is
2746 mostly missing, but it's a start.
2747 * support/regression/tests/bug-227710.c: fixed nonconforming use of
2748 reserved identifier "__data".

2826 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2828 * device/lib/printf_large.c: removed inline assembly for portability and
2829 readability. Use printf_fast if speed or size are more important.
2830 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2831 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2833 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2835 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2836 prevent compiler warning
2838 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2840 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2841 moved to level 0 and declared as static. Also they are explicit
2842 placed in access bank. This was necessery because some times they
2843 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2844 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2845 optimizations. Currently only compare to unsigned char is implemented,
2846 * src/pic16/gen.c: added fReturnIdx array,
2847 * (struct resolvedIfx) is moved to gen.h and made public,
2848 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2849 * (aopForSym): added an optimization to directly store in stack of
2850 the operand of a SEND iCode,
2851 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2852 but as registers instead (AOP_REG) using the fReturnIdx array,
2853 * (pic16_freeAsmop): remove the freed register from the
2854 _G.sregsAlloc field,
2855 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2856 a compare of 'WREG',
2857 * (pic16_popGetTempRegCond): changed function prototype, now
2858 function takes also a bitVector argument v which holds the current
2859 set of registers that are allocated for stack access by aopForSym,
2860 registers allocated in aopForSym for accessing stack symbols are not
2861 any more part of the functions usedRegs field,
2862 * (genCall): some times aopOp is called for a stack variable to be
2863 send, aopForSym might perform the push, if this is true make sure
2864 that genCall doesn't push the variable twice by testing _G.resDirect,
2865 * (genFunction): changed testing for unspecified interrupt number
2866 from 256 to INTNO_UNSPEC,
2867 * modified selection scheme of frame pointer generation. Previously
2868 if function did use local registers a frame pointer was generated,
2869 now a frame pointer is generated only if function has arguments
2870 (that need PLUSW2 register access), or has stack arguments, or the
2871 compiler is not instructed to omit the frame pointer,
2872 * (genEndFunction): before restoring local registers that were saved
2873 in the function preamble, also restore the registers that *might*
2874 have been allocated for stack access,
2875 * (genRet): removed some old comments,
2876 * (genCmp, the active (RN's) version): added a call to the
2877 pic16_genCmp_special function to perform the compare with a more
2878 robust and optimized way,
2879 * (genInline): a feature has been added in inline code generation,
2880 which allows a wildcard variable substitution when writing inline
2881 assembly. Code is incomplete and experimental therefore undocumented,
2882 * (genCast): changed order of aopOp for result and right to allow
2883 aopForSym to directly load the result if possible,
2884 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2885 perform an optimized compare on some selected special occasions,
2886 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2887 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2888 generate an IVT any more,
2889 * src/pic16/main.c (pic16_optionsTable): added command line option
2891 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2892 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2894 * src/pic16/NOTES: Raphael Neider added in list of active developers
2895 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2896 jumptable_end to prevent bug #,
2897 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2898 inCond and outCond fields,
2899 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2900 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2901 turn off register spilling,
2902 * (packRegsForOneUse): synced with other ports' versions although it
2903 is not used currently,
2904 * (pic16_packRegisters): added an optimization while reading
2905 structure bitfields, some registers may be saved (malloc code is
2906 decreased by 80 bytes)
2908 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2910 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2911 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2912 this can be optimized more?
2914 2005-03-10 Raphael Neider <rneider AT web.de>
2916 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2917 genNearPointerGet): (hopefully) fixed access to bitfields via
2918 pointers (p->bitN = x; and x = p->bitN; failed)
2920 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

2964 to keep the correct label reference count when adding/removing references
2965 to labels. A peephole file using this is appended to patch #1144962.

3552 Adding support for replacing ljmps with sjmps in jumptables
3553 generated for switch statements. For now you need to set the
3554 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3555 Now 4 algorithms for mcs51 jumptable generation are used:
3556 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3557 addresses loaded pc-relative for up to 112 cases and stack-pushing
3558 target addresses loaded with offset from dptr for up to 256 cases.

3588 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3590 * added libc directory. The current version of LibC contains string
3591 functions, ctype functions and macros and some functions of the
3592 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3593 be extensively tested in the future. Standard disclaimer here.
3594 Library is not automatically build yet. But one can build it by
3595 invoking 'make' inside the libc directory.
3596 * added ADC library under libio. Preliminary version yet.

3606 * (pic16_storeForReturn): optimized return of 0,
3607 * (genCmp): experimental code for new genCmp which uses PIC18's
3608 special compare&skip instructions. Initial tests fail some times
3609 with variables grater than 1 byte in size, so new code is disabled,
3610 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3612 * (genCast): began a fix to optimize the casting of a bit to another
3613 bit, now assigning a bitfield to another bitfield will fail, sorry,
3614 * src/pic16/main.c: disabled the use of lr-support feature,
3615 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

3622 and 1 for banking instruction,
3623 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3624 caused stop processing pCodes after a inline assembly block,
3625 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

3627 registers when it shouldn't,
3628 * src/pic16/ralloc.c (allocReg): add preliminary support for
3629 supporting a limited set of temporary registers,
3631 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6539 * support/regression/ports/ucz80/spec.mk (UCZ80): Made detect the
6542 * support/regression/generate-cases.py (main): Changed from inline
6545 * doc/Makefile (install): Changed to depth first to get rid of
6546 missing directory install warning.
6548 * as/Makefile (install-doc): Made work on Mac.
6550 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
6552 * src/SDCCast.c: added an additional type flow in decorateType() of
6553 opposite direction, see feature request #860006; it's enabled at runtime
6554 by setting the environment variable SDCC_NEWTYPEFLOW
6555 * src/SDCCast.h: changed prototype of decorateType()
6556 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
6557 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
6558 'char' to 'int' can be omitted, if both operands are 'unsigned char';
6559 see feature request #877103
6560 * src/SDCCval.c: updated call of decorateType()
6561 (valBitwise): fixed bug #882876
6562 (valMinus): added promotion
6563 (valLogicAndOr): result is unsigned
6564 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
6565 * src/SDCCsymt.c (computeType),
6566 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
6567 must not cause an unsigned operation
6568 * src/pic/glue (pic14emitRegularMap),
6569 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
6571 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>

6588 * src/pic/ralloc.h: applied patch from Slade Rich;
6589 added support for multiple code pages and multiple RAM banks on the
6590 PIC 14 port. The ASM files now no longer simply assume all the
6591 code / RAM are in the same page / bank. This means the linker can
6592 safely allocate code/RAM of separate ASM files to different pages/banks.
6593 * doc/sdccman.lyx: added Slade's tips
6594 * src/mcs51/peeph.def: fixed bug #880768

6603 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
6606 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
6607 strtof is not part of C89 and isn't included with Mac OS X.
6609 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6611 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

6636 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6638 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6639 loaded with the linker search paths (-L arguments) and the libraries
6640 to be linked with the current source (-l arguments). Changes
6641 currently will affect only the pic16 port.
6642 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6643 include path the port specific paths and port specific libraries,
6644 * gplink command now contains the $3 argument,
6645 * src/pic16/device.h,
6646 * src/pic16/device.c,: structure PIC_device is made public and
6647 renamed to PIC16_device, the same for variable Pics which is renamed

6662 Documenting changes from previous commits.
6663 * configure.in (version 1.56),
6664 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6665 when generating output files to configure the pic16 library,
6666 but now I've commented it out, since gputils aren't installed in the
6667 SF compile farm, so library won't compile
6669 * device/lib/Makefile.in (version 1.56): initially I've added in
6670 target 'all' the prerequestive 'model-pic16' so it compiled the
6671 pic16 library, but now I've commented it out for the same reasons
6673 * added targets 'model-pic16' and 'objects-pic16' to compile the
6675 * added target 'port-specific-objects-pic16' to handle the
6676 generated libraries and copy them into the build/ directory
6677 * added target 'clean-intermediate-pic16' to clean intermediate
6678 files into pic16 directory
6679 * in target 'installdirs' added line to create directory pic16 in
6680 the installation path
6682 * device/include/Makefile.in (version 1.11): in target 'install'
6683 added lines to copy all header files to installation path,
6684 * in target 'installdirs' added line create directory for pic16
6685 headers in the installation path

6700 * src/z80/main.c (_parseOptions): fixed the portmode= command line
6701 option so that it actually works. Made it specific to the z80, since
6702 the gbz80 doesn't have these kinds of I/O ports.
6704 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6706 * device/include/z180.h,

6728 Mainly changes to support compilation of the device libraries
6729 * src/pic16/device.c: stack is allocated via symbol and not
6730 via literal number. The symbol is placed in the corresponding
6731 position of the data ram
6732 * (pic16_dump_section): relocatable and absolute uninitialized
6733 data are now emitted in sorted order to reduce section naming,
6734 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6735 weren't marked as being in the access bank,
6737 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6739 Added portion of GNU PIC Library under the directory
6740 device/include/pic16 and device/lib/pic16. These files
6741 contain the declarations of SFRs for the PIC18Fxx2 devices.
6742 The directory is initialized via configure from toplevel.
6744 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

6772 all over. Telling LaTeX to be less strict with word spacing
6773 to better keep the right margin. Changed some notes about
6774 maintainance of the ports in section 3.2.1 - is it OK like this?
6776 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

6814 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
6816 * src/pic16/peeph.def: all peepholes with movff are commented out,
6817 because there is a problem in the pcode peep optimizer,
6818 * src/pic16/ralloc.c: the register allocator can now reuse local

6957 Bug reported from Jesus Calvino-Fraga
6959 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6961 * sdcc.spec: updated
6962 * device/include/Makefile.in: don't install CVS directories

6965 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6966 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6967 * src/ds390/gen.c (genRightShift): fixed bug #870788
6968 * src/SDCCast.c (decorateType): fixed bug #870781
6970 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6972 PIC16 port related changes:
6973 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6974 added variable stackPos,
6976 * gen.c: genCall, assignResultValue: added support for
6977 pushing/retrieving function parameters to/from stack,
6978 genFunction,genEndFunction: setup stack frame for the
6980 genAddrOf: will be changed according to bug 863624
6982 * added files genutils.c and genutils.h which contain gen*
6983 debugged and optimised functions extracted from gen.c
6985 * glue.c: added variable 'externs' which holds extern symbols,
6986 pic16emitRegularMap: is modified to properly handle relocatable
6987 symbols under the new scheme,
6988 pic16createInterruptVect: is modified
6989 pic16printPublics: is modified to emit 'global' assembler directives,
6990 added pic16_printExterns to print extern symbols,
6991 pic16glue: initializes stack/frame pointer in the beginning of
6992 the assembly output. Temporary hack, will be corrected later,
6993 because gplink yet does not support stack and SDCC does not
6994 yet support a type of crt0.o object to create the final binary.
6996 * Removed many lines that contain 8051 legacy code.
6997 * The code is finally placed under a 'code' directive.
6998 * Added port specific options.
7000 * _process_pragma: simplified since now we do not need *special*
7001 include file to define SFR registers. But a separate header
7002 will be needed. This will be developed later.
7003 * _pic16_parseOptions: added, parses port specific options:
7004 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7005 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7006 --preplace-udata-with=
7008 * _pic16_setDefaultOptions: modified to initialize section names,
7009 but hack is temporarly out of order since it needs improvement.
7010 * _pic16_genAssemblerPreamble: configuration words are emitted by
7011 their address instead of their name. This part is incomplete and
7012 supports only the 18Fxx2 devices. Other devices will emit an error
7013 during assembly since they do not contain the same set of config
7015 * _pic16_genIVT: is modified,
7017 * pcode.c: added definitions for some hardware registers that are needed
7019 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7020 All PCI entries are updated. Now LFSR is supported.
7021 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7022 * added pic16_newpCodeOpLit2 to support instructions with
7023 two literal arguments
7024 * pic16_pCode2str: corrected code that emits assembler instructions
7025 with two literal operands and those that have an access bit modifier
7026 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7027 this fixes a bug which caused some labels to be lost, when an
7028 assembler directive was added, i.e. banksel,
7029 * pic16_FixRegisterBanking: improved logic that causes the insertion
7031 * InlineFunction: functions that are called once, are not any more
7032 inlined. This can be a port option in the future,
7034 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7036 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7037 hold the corresponding uninitialized symbols,
7038 * pic16_allocProcessorRegister: registers have explicit marked the
7040 * pic16_allocInternalRegister: registers are explicit marked as
7042 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7043 processing list, so bit registers were lost,
7046 * ralloc.h: added field 'accessBank' and original symbol operand
7047 in register definition,
7048 * removed the field isMapped from register definition,
7050 ** Several functions have been removed from various sources:
7051 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7052 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7053 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7054 pic16_assignRelocatableRegisters
7056 ** others have been introduced:
7057 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7058 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7060 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7062 * support/scripts/inc2h.pl: changed definition of BIT_AT
7063 to emit 'sbit at' instead of 'bit at'. This was a request.
7065 PIC16 port related preliminary changes:
7066 * gen.c: prefixed function popRegFromString with
7067 pic16_ and all references to it corrected
7068 * pcode.c: all pic16_pc_* hardware registers prefixed
7069 with underscore (_),
7070 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7071 * ralloc.c: newReg(): when register is REG_SFR then
7072 set address to rIdx,
7073 pic16_allocProcessorRegister(): marks register wasUsed=0
7074 pic16_writeUsedRegs(): added a call to assign processor
7075 registers via pic16_assignFixedRegisters
7077 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7079 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7080 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7081 variables in unused register banks. Also the SSEG is placed
7082 wherever there is enough space for it, and IDATA can be anywhere
7083 in internal RAM. For now compile using -Wl-Y[stack_size].
7084 The mem file is different for this option as well, since it
7085 makes no sense of talking about DSEG lenght.
7087 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7089 * src/SDCClrange.c: fixed bug 869095 that caused segfault

7334 * src/SDCCast.c (decorateType): disabled a transformation I added in
7335 revision 1.188 (access to fields of a structure at an absolute address);
7336 it breaks with bitfields, extern declarations, and gcse analysis.
7337 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7338 could be assigned through a pointer, so don't complain.

7446 xdata initialization slightly shorter
7448 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8095 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8096 fetching of the pointer
8097 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8098 copied from genNearPointerSet()
8099 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8100 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

8114 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8116 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8117 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8118 type for bits was changed. It resulted in bit variables becoming
8119 global, which is not permitted in PIC 14 assembly output.
8121 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8123 * doc/sdccman.lyx: various additions and updates. Rearranged sections
8125 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8127 Z80 and MCS51 linkers complaint if a public symbol is defined
8128 in more than one library module:

8136 A few small changes that speed up the peephole optimizer.
8140 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8142 Try to make the peephole optimizer smarter by maintaining
8143 an association between the assembly source code and the
8144 iCodes that originated them. Put this information to use
8145 with a new peephole rule condition "notVolatile" so that
8146 the rules can be aggressive yet still safe.
8151 * src/mcs51/peeph.def
8153 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8157 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8158 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8159 if the left or right operand symbols have the accuse flag set.
8161 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8163 Changed the type of the result of the ! (NOT) operator to char;
8164 previously it returned the same type as the source. This allows
8165 us to eliminate all the genFloatNot functions (all of its target
8166 implementations were very buggy) since !float can use the same
8169 * src/SDCCicode.c (ast2iCode): ! returns char
8170 * src/mcs51/gen.c (genNot, genNotFloat),
8171 * src/ds390/gen.c (genNot, genNotFloat),
8172 * src/z80/gen.c (genNot, genNotFloat),
8173 * src/pic/gen.c (genNot, genNotFloat),
8174 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
8176 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
8178 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8179 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8180 during interrupts. Ensure WSAVE is located at a shared bank address.
8181 2. Fixed page selection in some places
8182 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8183 the registers name strings.
8184 4. Fixed "signed / unsigned compare" compiler warnings.
8185 5. The PIC port manages its own allocation of the general purpose
8186 registers, but makes no attempt to reuse them. As a result when
8187 compiling it soon runs out of general purpose registers. Some
8188 additional code was added to the files pcode.c and device.c to walk
8189 through the function call tree and rename the registers so that they
8199 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8200 genPlus() & genMinus() when the result is the same as left or right

8206 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8208 Made bitfield a distinct type from bit so that bitfields
8209 convert as per ANSI C and bits retain their traditional
8210 boolean style behaviour. Implemented bitfield support in
8218 * src/ds390/gen.c: bit v bitfield split
8219 * src/z80/gen.c: New support for bitfields
8220 * support/regression/tests/bitfields.c: reenabled z80,
8223 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8225 Rules 246.x, 247.x relate to bitfields, the others speed up
8226 access to xdata mapped I/O devices.
8228 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8230 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8232 Cleaned up genPackBits and genUnpackBits and added two helper
8233 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8234 for literal assignments in genPackBits (thanks to Frieder for
8240 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8242 Fixed bug #748310 (pointer to function type mishandled when the
8243 function name is omitted). Also fixed a SIGSEGV when a function
8244 attribute (reentrant, etc) is used on a non-function or on a
8245 function but misplaced before the parameter list.
8247 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8249 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8250 * support/Util/SDCCerr.h,
8251 * support/Util/SDCCerr.c: Added func attr misuse error msg

8272 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8274 Made the constant following the "interrupt" keyword optional. If
8275 omitted, the function will not automatically be given an entry
8276 in the interrupt vector table (similar to #pragma NOIV, but
8277 less syntacticly kludgy). The interrupt number is also now
8278 range checked. Also fixed a bug in the high order bit example
8285 * support/Util/SDCCerr.c
8286 * support/Util/SDCCerr.h
8289 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

8292 * src/SDCCicode.c (operandOperation): rewritten some ops
8293 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8294 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8296 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8297 be re-activated by defining REDUCE_LITERALS)
8298 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8299 unsigned, but are signed by default
8300 * src/SDCCval.c (constVal): rearranged
8301 * src/SDCCval.c (valMod): preliminary fix
8302 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8345 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
8346 * src/SDCCval.c (valDiv, valMod): fixed signdness
8347 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
8348 signedness of modulo, left and right shift

8754 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
8755 the regression tests I'm not brave enough to enable 245.b, 245.c
8756 * doc/sdccman.lyx: added latex preamble for hyperref package.
8757 Using pdflatex this will give you a hyperlinked pdf file with
8758 bookmarks. (prepend '%' before /usepackage if this breaks something)

8799 it can be defined with CFLAGS when running configure
8800 * src/SDCCmain.c: fixed compiling + linking with object files
8802 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

8805 added --disable-pic16-port
8806 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
8807 * src/SDCCmain.c: linkOptions is changed to set *,
8808 added if/endif conditional macros to remove options help
8809 messages from optionsTable when a port is not configured, added
8810 support for the PIc16 port in the ports table, when executing
8811 the compiler with no port specified on command line, a default
8812 port is selected with the new macro DEFAULT_PORT which is
8813 defined in port.h, in setDefaultOptions() linkOptions is removed
8814 from initialization assignment, since now it is a set,
8815 parseCmdLine uses setParseWithComma for linkOptions, in
8816 linkEdit() linkOptions are accessed with new function indexSet()
8817 which returns the i'th item of a set variable. See SDCCset.c, in
8818 linkEdit() when calling buildCmdLine(), added linkOptions as
8819 last argument. Now users can pass arguments to gplink via the
8820 -Wl option, main() uses pic16glue() to glue up pic16 programs

8832 * src/pic16/glue.c: commented out some error producing lines
8833 * src/pic16/main.c: __config directives are commented out to stop
8834 gpasm complaining and test the linkage with gplink, _linkCmd and
8835 _asmCmd changed to be more gplink and gpasm friendly
8836 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8837 produced an error when parsed, peep rule 12 is added to utilize
8838 movff, but it is commented out since the pCode does not support
8839 yet a command with 2 address arguments
8841 2003-05-18 <johan AT balder>
8843 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
8844 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8870 2003-05-11 Borut Razem <borut.razem AT siol.net>
8872 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
8873 the path of bin directory, so that PATH is the only env. variable, which has to be set
8874 in case of standard installation.
8875 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

9957 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9958 not bytes. Function summary() which creates a memory usage summary
9959 file with extension .mem. Reports of overlaping stack and small stack
9960 size. If the space for the stack is less than 16 bytes aslink trows a
9963 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9964 the 8051. Option 'y' for memory summary output file.
9966 Changes to sdcc (All the changes are marked with 'JCF'):
9968 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9970 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9971 overlaying area for it (uses RegBankUsed[4]).
9973 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9974 bank zero as used by default. By default aslink locates the stack
9975 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9976 the creation of the .mem file. Delegates the allocation of data area
9977 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9978 the begining of the stack area to aslink.
9980 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9981 glue() in SDCCglue.c creates an area for it.
9983 2002-09-03 Borut Razem <borut.razem AT siol.net>
9984 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9985 sdcc/src/pic/glue.c:
9986 introduced atexit() handler for teporay files removal in case of
9987 errors, assertions, ...
9989 2002-08-29 Borut Razem <borut.razem AT siol.net>
9990 * sdcc/support/cpp2/auto-host_vc_in.h:
9991 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9992 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9993 Maybe there is a similar problem with BORLANDC? It should be checked!
9995 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9996 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9997 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9998 was not executed, and the compiler (cl) launched a warning:
9999 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10001 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10002 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10004 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10005 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10007 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10008 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10009 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10010 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10011 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10012 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10013 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10014 - added Release configuration in VS projects
10015 - review of compiler an linker options
10016 - VC .exe files are generated in bin_vc directory, not to interfere
10017 with binaries generated from other projects (cygwin, mingw, bcc ...)
10019 * sdcc/src/yacc.dsp: added
10021 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10022 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10023 and insert the version number definitions from .version
10025 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10027 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10028 added - genarate auto-host.h using auto-host_vc_in.h as template
10031 removed from CVS, generated automatically
10033 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10034 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10036 2002-08-11 Borut Razem <borut.razem AT siol.net>
10037 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10039 2002-08-10 Borut Razem <borut.razem AT siol.net>
10040 * src/SDCCmain.c (main):
10041 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10042 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10043 The consequence was that some temporary files were not removed.
10046 unification of code in functions tempfilename() and tempfile():
10047 function tempnam() is defined in Visual Studio 6.0 and .NET
10049 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10051 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10052 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10053 - removed compiler command line option /WX: Treats all warnings as errors
10054 - update a list of source files, included into the project
10056 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10057 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10058 changed project type to Generic Project so that can be correcly converted to VS.NET project
10060 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10062 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10064 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10066 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10067 added return 0 statements after assert() to make compiler happy
10069 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10070 added newline in the def file to keep MSC compiler satisfied
10072 * sdcc/src/z80/gen.c:
10073 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10074 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10075 - solved MSC error in function aopDump()
10077 * sdcc_vc.h: define PREFIX as "\\sdcc"
10079 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10080 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10128 Added -p option. Allows port dependent processor to be specified.
10131 Initialized the new field char *Processor field to NULL in all ports
10134 Compiler generated registers for interrupt context saving
10135 were not getting allocated.
10137 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10140 Fixed left shift. Will promote the left side of a left shift
10141 if a) left shifting more than size of operand or b) when assigned

10252 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10254 * sdcc/src/SDCCloop.c:
10255 Previous fix was not good. basic blocks that have "break" or "return" are
10256 not really partof a loop , but live ranges used in these blocks should
10257 be live thru the entire loop, so set partOfLoop but don't add them to
10260 2002-02-21 <johan AT FRIJA>
10262 * src/SDCCcse.c: fixed bug #514308
10264 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
