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

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

460 * src/pic16/gen.c (genPcall): fixed bug #1443644
461 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
462 which dumps before the function entry point a data byte which represents
463 the number of the local variables used by the specified function, added
464 'xinst' for initial support for Extended Instruction Support,
465 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
466 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
467 port->fun_prefix anymore (may change later),
468 (genFunction, genEndFunction): do not store/restore local registers for
469 _main (this should take care the --main-return command line option in
471 (genOr): removed some legacy pic-port instructions,
472 * src/pic16/genarith.c (genAddLit): re-enabled old code because
473 performing operations with SFR's causes data to be written more than
474 once to each SFR. Perhaps SFRs should be handled in special cases...
475 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
477 * src/pic16/main.c (_process_pragma): stack bound checking did not take
478 into account for stack starting position,
479 (struct OPTIONS pic16_optionsTable): added command line argument
480 --extended or -y for Extended Instruction Support,
481 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
482 (deassignLRs): *** perhaps the most important change, old 'for' code
483 (commented out for reference), didn't account for some registers which
484 were left marked 'not free' after a pointer operation. The change
485 reduces register usage a lot in some cases

2760 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
2761 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
2762 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
2763 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
2764 always available in leading double underscore form. The C99 support is
2765 mostly missing, but it's a start.
2766 * support/regression/tests/bug-227710.c: fixed nonconforming use of
2767 reserved identifier "__data".
2769 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

2845 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2847 * device/lib/printf_large.c: removed inline assembly for portability and
2848 readability. Use printf_fast if speed or size are more important.
2849 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2850 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2852 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2854 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2855 prevent compiler warning
2857 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2859 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2860 moved to level 0 and declared as static. Also they are explicit
2861 placed in access bank. This was necessery because some times they
2862 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2863 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2864 optimizations. Currently only compare to unsigned char is implemented,
2865 * src/pic16/gen.c: added fReturnIdx array,
2866 * (struct resolvedIfx) is moved to gen.h and made public,
2867 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2868 * (aopForSym): added an optimization to directly store in stack of
2869 the operand of a SEND iCode,
2870 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2871 but as registers instead (AOP_REG) using the fReturnIdx array,
2872 * (pic16_freeAsmop): remove the freed register from the
2873 _G.sregsAlloc field,
2874 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2875 a compare of 'WREG',
2876 * (pic16_popGetTempRegCond): changed function prototype, now
2877 function takes also a bitVector argument v which holds the current
2878 set of registers that are allocated for stack access by aopForSym,
2879 registers allocated in aopForSym for accessing stack symbols are not
2880 any more part of the functions usedRegs field,
2881 * (genCall): some times aopOp is called for a stack variable to be
2882 send, aopForSym might perform the push, if this is true make sure
2883 that genCall doesn't push the variable twice by testing _G.resDirect,
2884 * (genFunction): changed testing for unspecified interrupt number
2885 from 256 to INTNO_UNSPEC,
2886 * modified selection scheme of frame pointer generation. Previously
2887 if function did use local registers a frame pointer was generated,
2888 now a frame pointer is generated only if function has arguments
2889 (that need PLUSW2 register access), or has stack arguments, or the
2890 compiler is not instructed to omit the frame pointer,
2891 * (genEndFunction): before restoring local registers that were saved
2892 in the function preamble, also restore the registers that *might*
2893 have been allocated for stack access,
2894 * (genRet): removed some old comments,
2895 * (genCmp, the active (RN's) version): added a call to the
2896 pic16_genCmp_special function to perform the compare with a more
2897 robust and optimized way,
2898 * (genInline): a feature has been added in inline code generation,
2899 which allows a wildcard variable substitution when writing inline
2900 assembly. Code is incomplete and experimental therefore undocumented,
2901 * (genCast): changed order of aopOp for result and right to allow
2902 aopForSym to directly load the result if possible,
2903 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2904 perform an optimized compare on some selected special occasions,
2905 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2906 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2907 generate an IVT any more,
2908 * src/pic16/main.c (pic16_optionsTable): added command line option
2910 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2911 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2913 * src/pic16/NOTES: Raphael Neider added in list of active developers
2914 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2915 jumptable_end to prevent bug #,
2916 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2917 inCond and outCond fields,
2918 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2919 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2920 turn off register spilling,
2921 * (packRegsForOneUse): synced with other ports' versions although it
2922 is not used currently,
2923 * (pic16_packRegisters): added an optimization while reading
2924 structure bitfields, some registers may be saved (malloc code is
2925 decreased by 80 bytes)
2927 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2929 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2930 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2931 this can be optimized more?
2933 2005-03-10 Raphael Neider <rneider AT web.de>
2935 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2936 genNearPointerGet): (hopefully) fixed access to bitfields via
2937 pointers (p->bitN = x; and x = p->bitN; failed)

2982 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
2983 to keep the correct label reference count when adding/removing references
2984 to labels. A peephole file using this is appended to patch #1144962.

3571 Adding support for replacing ljmps with sjmps in jumptables
3572 generated for switch statements. For now you need to set the
3573 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3574 Now 4 algorithms for mcs51 jumptable generation are used:
3575 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3576 addresses loaded pc-relative for up to 112 cases and stack-pushing
3577 target addresses loaded with offset from dptr for up to 256 cases.

3607 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3609 * added libc directory. The current version of LibC contains string
3610 functions, ctype functions and macros and some functions of the
3611 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3612 be extensively tested in the future. Standard disclaimer here.
3613 Library is not automatically build yet. But one can build it by
3614 invoking 'make' inside the libc directory.
3615 * added ADC library under libio. Preliminary version yet.

3625 * (pic16_storeForReturn): optimized return of 0,
3626 * (genCmp): experimental code for new genCmp which uses PIC18's
3627 special compare&skip instructions. Initial tests fail some times
3628 with variables grater than 1 byte in size, so new code is disabled,
3629 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3631 * (genCast): began a fix to optimize the casting of a bit to another
3632 bit, now assigning a bitfield to another bitfield will fail, sorry,

3641 and 1 for banking instruction,
3642 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3643 caused stop processing pCodes after a inline assembly block,
3644 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

3646 registers when it shouldn't,
3647 * src/pic16/ralloc.c (allocReg): add preliminary support for
3648 supporting a limited set of temporary registers,
3650 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6538 2004-01-27 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6540 * ChangeLog: changed "@" to " AT " in hopes of reducing spam and
6541 virus/worm forged address usage.
6543 2004-01-27 Bernhard Held <bernhard AT bernhardheld.de>
6545 Fixed promotion, it should be done on AST level:
6546 * src/SDCCast.c (addCast): added promotion to int
6547 (decorateType): updated call to upCast()
6548 * src/SDCCicode.c (geniCodeLeftShift): removed call to
6549 usualUnaryConversions()
6551 2004-01-26 Michael Hope <michaelh AT juju.net.nz>
6553 * support/regression/tests/literalop.c (mulWrapper): Added a
6554 wrapper to remove integer overflow warnings.
6556 * support/regression/tests/float_trans.c: Made work on host.
6558 * support/regression/ports/ucz80/spec.mk (UCZ80): Made detect the
6561 * support/regression/generate-cases.py (main): Changed from inline
6564 * doc/Makefile (install): Changed to depth first to get rid of
6565 missing directory install warning.
6567 * as/Makefile (install-doc): Made work on Mac.
6569 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
6571 * src/SDCCast.c: added an additional type flow in decorateType() of
6572 opposite direction, see feature request #860006; it's enabled at runtime
6573 by setting the environment variable SDCC_NEWTYPEFLOW
6574 * src/SDCCast.h: changed prototype of decorateType()
6575 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
6576 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
6577 'char' to 'int' can be omitted, if both operands are 'unsigned char';
6578 see feature request #877103
6579 * src/SDCCval.c: updated call of decorateType()
6580 (valBitwise): fixed bug #882876
6581 (valMinus): added promotion
6582 (valLogicAndOr): result is unsigned
6583 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
6584 * src/SDCCsymt.c (computeType),
6585 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
6586 must not cause an unsigned operation

6607 * src/pic/ralloc.h: applied patch from Slade Rich;
6608 added support for multiple code pages and multiple RAM banks on the
6609 PIC 14 port. The ASM files now no longer simply assume all the
6610 code / RAM are in the same page / bank. This means the linker can
6611 safely allocate code/RAM of separate ASM files to different pages/banks.
6612 * doc/sdccman.lyx: added Slade's tips
6613 * src/mcs51/peeph.def: fixed bug #880768

6625 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
6626 strtof is not part of C89 and isn't included with Mac OS X.
6628 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6630 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

6655 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6657 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6658 loaded with the linker search paths (-L arguments) and the libraries
6659 to be linked with the current source (-l arguments). Changes
6660 currently will affect only the pic16 port.
6661 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6662 include path the port specific paths and port specific libraries,
6663 * gplink command now contains the $3 argument,
6664 * src/pic16/device.h,
6665 * src/pic16/device.c,: structure PIC_device is made public and
6666 renamed to PIC16_device, the same for variable Pics which is renamed

6681 Documenting changes from previous commits.
6682 * configure.in (version 1.56),
6683 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6684 when generating output files to configure the pic16 library,
6685 but now I've commented it out, since gputils aren't installed in the
6686 SF compile farm, so library won't compile
6688 * device/lib/Makefile.in (version 1.56): initially I've added in
6689 target 'all' the prerequestive 'model-pic16' so it compiled the
6690 pic16 library, but now I've commented it out for the same reasons
6692 * added targets 'model-pic16' and 'objects-pic16' to compile the
6694 * added target 'port-specific-objects-pic16' to handle the
6695 generated libraries and copy them into the build/ directory
6696 * added target 'clean-intermediate-pic16' to clean intermediate
6697 files into pic16 directory
6698 * in target 'installdirs' added line to create directory pic16 in
6699 the installation path
6701 * device/include/Makefile.in (version 1.11): in target 'install'
6702 added lines to copy all header files to installation path,
6703 * in target 'installdirs' added line create directory for pic16
6704 headers in the installation path

6719 * src/z80/main.c (_parseOptions): fixed the portmode= command line
6720 option so that it actually works. Made it specific to the z80, since
6721 the gbz80 doesn't have these kinds of I/O ports.
6723 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6725 * device/include/z180.h,

6747 Mainly changes to support compilation of the device libraries
6748 * src/pic16/device.c: stack is allocated via symbol and not
6749 via literal number. The symbol is placed in the corresponding
6750 position of the data ram
6751 * (pic16_dump_section): relocatable and absolute uninitialized
6752 data are now emitted in sorted order to reduce section naming,
6753 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6754 weren't marked as being in the access bank,
6756 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6758 Added portion of GNU PIC Library under the directory
6759 device/include/pic16 and device/lib/pic16. These files
6760 contain the declarations of SFRs for the PIC18Fxx2 devices.
6761 The directory is initialized via configure from toplevel.
6763 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
6765 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

6791 all over. Telling LaTeX to be less strict with word spacing
6792 to better keep the right margin. Changed some notes about
6793 maintainance of the ports in section 3.2.1 - is it OK like this?
6795 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

6833 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
6835 * src/pic16/peeph.def: all peepholes with movff are commented out,
6836 because there is a problem in the pcode peep optimizer,
6837 * src/pic16/ralloc.c: the register allocator can now reuse local

6976 Bug reported from Jesus Calvino-Fraga
6978 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6980 * sdcc.spec: updated
6981 * device/include/Makefile.in: don't install CVS directories

6983 * doc/Makefile: fixed install, added local_icons
6984 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6985 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6986 * src/ds390/gen.c (genRightShift): fixed bug #870788
6987 * src/SDCCast.c (decorateType): fixed bug #870781
6989 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6991 PIC16 port related changes:
6992 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6993 added variable stackPos,
6995 * gen.c: genCall, assignResultValue: added support for
6996 pushing/retrieving function parameters to/from stack,
6997 genFunction,genEndFunction: setup stack frame for the
6999 genAddrOf: will be changed according to bug 863624
7001 * added files genutils.c and genutils.h which contain gen*
7002 debugged and optimised functions extracted from gen.c
7004 * glue.c: added variable 'externs' which holds extern symbols,
7005 pic16emitRegularMap: is modified to properly handle relocatable
7006 symbols under the new scheme,
7007 pic16createInterruptVect: is modified
7008 pic16printPublics: is modified to emit 'global' assembler directives,
7009 added pic16_printExterns to print extern symbols,
7010 pic16glue: initializes stack/frame pointer in the beginning of
7011 the assembly output. Temporary hack, will be corrected later,
7012 because gplink yet does not support stack and SDCC does not
7013 yet support a type of crt0.o object to create the final binary.
7015 * Removed many lines that contain 8051 legacy code.
7016 * The code is finally placed under a 'code' directive.
7017 * Added port specific options.
7019 * _process_pragma: simplified since now we do not need *special*
7020 include file to define SFR registers. But a separate header
7021 will be needed. This will be developed later.
7022 * _pic16_parseOptions: added, parses port specific options:
7023 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7024 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7025 --preplace-udata-with=
7027 * _pic16_setDefaultOptions: modified to initialize section names,
7028 but hack is temporarly out of order since it needs improvement.
7029 * _pic16_genAssemblerPreamble: configuration words are emitted by
7030 their address instead of their name. This part is incomplete and
7031 supports only the 18Fxx2 devices. Other devices will emit an error
7032 during assembly since they do not contain the same set of config
7034 * _pic16_genIVT: is modified,
7036 * pcode.c: added definitions for some hardware registers that are needed
7038 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7039 All PCI entries are updated. Now LFSR is supported.
7040 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7041 * added pic16_newpCodeOpLit2 to support instructions with
7042 two literal arguments
7043 * pic16_pCode2str: corrected code that emits assembler instructions
7044 with two literal operands and those that have an access bit modifier
7045 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7046 this fixes a bug which caused some labels to be lost, when an
7047 assembler directive was added, i.e. banksel,
7048 * pic16_FixRegisterBanking: improved logic that causes the insertion
7050 * InlineFunction: functions that are called once, are not any more
7051 inlined. This can be a port option in the future,
7053 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7055 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7056 hold the corresponding uninitialized symbols,
7057 * pic16_allocProcessorRegister: registers have explicit marked the
7059 * pic16_allocInternalRegister: registers are explicit marked as
7061 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7062 processing list, so bit registers were lost,
7065 * ralloc.h: added field 'accessBank' and original symbol operand
7066 in register definition,
7067 * removed the field isMapped from register definition,
7069 ** Several functions have been removed from various sources:
7070 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7071 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7072 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7073 pic16_assignRelocatableRegisters
7075 ** others have been introduced:
7076 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7077 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7079 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7081 * support/scripts/inc2h.pl: changed definition of BIT_AT
7082 to emit 'sbit at' instead of 'bit at'. This was a request.
7084 PIC16 port related preliminary changes:
7085 * gen.c: prefixed function popRegFromString with
7086 pic16_ and all references to it corrected
7087 * pcode.c: all pic16_pc_* hardware registers prefixed
7088 with underscore (_),
7089 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7090 * ralloc.c: newReg(): when register is REG_SFR then
7091 set address to rIdx,
7092 pic16_allocProcessorRegister(): marks register wasUsed=0
7093 pic16_writeUsedRegs(): added a call to assign processor
7094 registers via pic16_assignFixedRegisters
7096 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7098 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7099 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7100 variables in unused register banks. Also the SSEG is placed
7101 wherever there is enough space for it, and IDATA can be anywhere
7102 in internal RAM. For now compile using -Wl-Y[stack_size].
7103 The mem file is different for this option as well, since it
7104 makes no sense of talking about DSEG lenght.
7106 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7108 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7109 in certain cases, e.g. when ROM assignment, patch provided
7110 from Albert den Haan.

7353 * src/SDCCast.c (decorateType): disabled a transformation I added in
7354 revision 1.188 (access to fields of a structure at an absolute address);
7355 it breaks with bitfields, extern declarations, and gcse analysis.
7356 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7357 could be assigned through a pointer, so don't complain.

7465 xdata initialization slightly shorter
7467 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8114 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8115 fetching of the pointer
8116 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8117 copied from genNearPointerSet()
8118 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8119 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

8135 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8136 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8137 type for bits was changed. It resulted in bit variables becoming
8138 global, which is not permitted in PIC 14 assembly output.
8140 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8142 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8155 A few small changes that speed up the peephole optimizer.
8159 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8161 Try to make the peephole optimizer smarter by maintaining
8162 an association between the assembly source code and the
8163 iCodes that originated them. Put this information to use
8164 with a new peephole rule condition "notVolatile" so that
8165 the rules can be aggressive yet still safe.
8170 * src/mcs51/peeph.def
8172 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8176 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8177 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8178 if the left or right operand symbols have the accuse flag set.
8180 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8182 Changed the type of the result of the ! (NOT) operator to char;
8183 previously it returned the same type as the source. This allows
8184 us to eliminate all the genFloatNot functions (all of its target
8185 implementations were very buggy) since !float can use the same
8188 * src/SDCCicode.c (ast2iCode): ! returns char

8197 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8198 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8199 during interrupts. Ensure WSAVE is located at a shared bank address.
8200 2. Fixed page selection in some places
8201 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8202 the registers name strings.
8203 4. Fixed "signed / unsigned compare" compiler warnings.
8204 5. The PIC port manages its own allocation of the general purpose
8205 registers, but makes no attempt to reuse them. As a result when
8206 compiling it soon runs out of general purpose registers. Some
8207 additional code was added to the files pcode.c and device.c to walk
8208 through the function call tree and rename the registers so that they
8218 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8219 genPlus() & genMinus() when the result is the same as left or right

8225 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8227 Made bitfield a distinct type from bit so that bitfields
8228 convert as per ANSI C and bits retain their traditional
8229 boolean style behaviour. Implemented bitfield support in
8237 * src/ds390/gen.c: bit v bitfield split
8238 * src/z80/gen.c: New support for bitfields
8239 * support/regression/tests/bitfields.c: reenabled z80,
8242 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8244 Rules 246.x, 247.x relate to bitfields, the others speed up
8245 access to xdata mapped I/O devices.
8247 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8249 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8251 Cleaned up genPackBits and genUnpackBits and added two helper
8252 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8253 for literal assignments in genPackBits (thanks to Frieder for
8259 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8261 Fixed bug #748310 (pointer to function type mishandled when the
8262 function name is omitted). Also fixed a SIGSEGV when a function
8263 attribute (reentrant, etc) is used on a non-function or on a
8264 function but misplaced before the parameter list.
8266 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8268 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8269 * support/Util/SDCCerr.h,
8270 * support/Util/SDCCerr.c: Added func attr misuse error msg

8291 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8293 Made the constant following the "interrupt" keyword optional. If
8294 omitted, the function will not automatically be given an entry
8295 in the interrupt vector table (similar to #pragma NOIV, but
8296 less syntacticly kludgy). The interrupt number is also now
8297 range checked. Also fixed a bug in the high order bit example

8305 * support/Util/SDCCerr.h
8308 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
8310 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
8311 * src/SDCCicode.c (operandOperation): rewritten some ops
8312 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8313 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8315 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8316 be re-activated by defining REDUCE_LITERALS)
8317 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8318 unsigned, but are signed by default
8319 * src/SDCCval.c (constVal): rearranged
8320 * src/SDCCval.c (valMod): preliminary fix
8321 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8363 constants are unsigned; added recognition of "u" flag for unsigned
8364 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
8365 * src/SDCCval.c (valDiv, valMod): fixed signdness
8366 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
8367 signedness of modulo, left and right shift

8818 it can be defined with CFLAGS when running configure
8819 * src/SDCCmain.c: fixed compiling + linking with object files
8821 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

8824 added --disable-pic16-port
8825 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
8826 * src/SDCCmain.c: linkOptions is changed to set *,
8827 added if/endif conditional macros to remove options help
8828 messages from optionsTable when a port is not configured, added
8829 support for the PIc16 port in the ports table, when executing
8830 the compiler with no port specified on command line, a default
8831 port is selected with the new macro DEFAULT_PORT which is
8832 defined in port.h, in setDefaultOptions() linkOptions is removed
8833 from initialization assignment, since now it is a set,
8834 parseCmdLine uses setParseWithComma for linkOptions, in
8835 linkEdit() linkOptions are accessed with new function indexSet()
8836 which returns the i'th item of a set variable. See SDCCset.c, in
8837 linkEdit() when calling buildCmdLine(), added linkOptions as
8838 last argument. Now users can pass arguments to gplink via the
8839 -Wl option, main() uses pic16glue() to glue up pic16 programs
8840 * src/SDCCpeeph.c: various changes to support pic16

8851 * src/pic16/glue.c: commented out some error producing lines
8852 * src/pic16/main.c: __config directives are commented out to stop
8853 gpasm complaining and test the linkage with gplink, _linkCmd and
8854 _asmCmd changed to be more gplink and gpasm friendly
8855 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8856 produced an error when parsed, peep rule 12 is added to utilize
8857 movff, but it is commented out since the pCode does not support
8858 yet a command with 2 address arguments
8860 2003-05-18 <johan AT balder>
8862 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
8863 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8889 2003-05-11 Borut Razem <borut.razem AT siol.net>
8891 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
8892 the path of bin directory, so that PATH is the only env. variable, which has to be set
8893 in case of standard installation.
8894 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

9951 added aopGetUsesAcc() function to allow binary operators to
9952 fetch their operands in the correct order; made genMinus() emit
9953 compact code for X = LITERAL - Y
9955 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9956 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9957 sprintf() in line 1267.
9959 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9960 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9963 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9964 Changes to aslink (All the changes are marked with 'JCF'):
9966 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9969 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9970 area BSEG. Also moves, if possible, the DATA area down into the internal
9971 ram so more space is available.
9973 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9976 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9977 not bytes. Function summary() which creates a memory usage summary
9978 file with extension .mem. Reports of overlaping stack and small stack
9979 size. If the space for the stack is less than 16 bytes aslink trows a
9982 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9983 the 8051. Option 'y' for memory summary output file.
9985 Changes to sdcc (All the changes are marked with 'JCF'):
9987 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9989 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9990 overlaying area for it (uses RegBankUsed[4]).
9992 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9993 bank zero as used by default. By default aslink locates the stack
9994 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9995 the creation of the .mem file. Delegates the allocation of data area
9996 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9997 the begining of the stack area to aslink.
9999 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10000 glue() in SDCCglue.c creates an area for it.
10002 2002-09-03 Borut Razem <borut.razem AT siol.net>
10003 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10004 sdcc/src/pic/glue.c:
10005 introduced atexit() handler for teporay files removal in case of
10006 errors, assertions, ...
10008 2002-08-29 Borut Razem <borut.razem AT siol.net>
10009 * sdcc/support/cpp2/auto-host_vc_in.h:
10010 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10011 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10012 Maybe there is a similar problem with BORLANDC? It should be checked!
10014 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10015 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10016 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10017 was not executed, and the compiler (cl) launched a warning:
10018 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10020 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10021 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10023 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10024 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10026 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10027 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10028 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10029 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10030 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10031 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10032 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10033 - added Release configuration in VS projects
10034 - review of compiler an linker options
10035 - VC .exe files are generated in bin_vc directory, not to interfere
10036 with binaries generated from other projects (cygwin, mingw, bcc ...)
10038 * sdcc/src/yacc.dsp: added
10040 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10041 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10042 and insert the version number definitions from .version
10044 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10046 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10047 added - genarate auto-host.h using auto-host_vc_in.h as template
10050 removed from CVS, generated automatically
10052 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10053 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10055 2002-08-11 Borut Razem <borut.razem AT siol.net>
10056 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10058 2002-08-10 Borut Razem <borut.razem AT siol.net>
10059 * src/SDCCmain.c (main):
10060 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10061 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10062 The consequence was that some temporary files were not removed.
10065 unification of code in functions tempfilename() and tempfile():
10066 function tempnam() is defined in Visual Studio 6.0 and .NET
10068 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10070 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10071 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10072 - removed compiler command line option /WX: Treats all warnings as errors
10073 - update a list of source files, included into the project
10075 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10076 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10077 changed project type to Generic Project so that can be correcly converted to VS.NET project
10079 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10081 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10083 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10085 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10086 added return 0 statements after assert() to make compiler happy
10088 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10089 added newline in the def file to keep MSC compiler satisfied
10091 * sdcc/src/z80/gen.c:
10092 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10093 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10094 - solved MSC error in function aopDump()
10096 * sdcc_vc.h: define PREFIX as "\\sdcc"
10098 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10099 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10136 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10138 2002-03-28 Johan Knol <johan AT balder>
10140 * src/SDCCval.c: fixed bug #532436
10142 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10144 Added "char *Processor" field to the port structure.
10147 Added -p option. Allows port dependent processor to be specified.
10150 Initialized the new field char *Processor field to NULL in all ports
10153 Compiler generated registers for interrupt context saving
10154 were not getting allocated.
10156 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10159 Fixed left shift. Will promote the left side of a left shift
10160 if a) left shifting more than size of operand or b) when assigned
10161 to something size > size of left side

10271 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10273 * sdcc/src/SDCCloop.c:
10274 Previous fix was not good. basic blocks that have "break" or "return" are
10275 not really partof a loop , but live ranges used in these blocks should
10276 be live thru the entire loop, so set partOfLoop but don't add them to
10279 2002-02-21 <johan AT FRIJA>
10281 * src/SDCCcse.c: fixed bug #514308
10283 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
