3035 * install-sh: fix bug #1204398 by setting umask 0022
3036 * device/lib/Makefile: separate build of z80 and gbz80 lib
3038 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
3040 Enabled VPATH feature: changed nearly all Makefiles (149 files).
3041 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
3043 One basic decision: e.g. src/clean.mk includes further files. In order
3044 to make this work there are two solutions:
3045 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
3046 run configure on them. This way they can use
3047 'include $(srcdir)/port-clean.mk'
3048 - always include clean.mk by the Makefile at the same level. To avoid
3049 that `make clean` tries to include and build Makefile.dep the
3050 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
3051 implemented, because now even `make uninstall` doesn't create
3052 Makefile.in. clean.mk could be eliminated by pasting it in
3055 * debugger/mcs51/Makefile.in: build own objects from library sources
3056 (SLIB, SDCC) in current directory
3058 * configure, configure.in: renamed --disable-device-lib-build in
3059 --disable-device-lib; added --enable-doc, the required tools are
3060 searched by configure; added result message; the toolchain for the
3061 belonging ports are now only built, if the port is enabled.
3063 * support/regression/*: all output is written in directory gen, because
3064 the fwk and ports directories don't livet in the build tree using vpath
3066 * doc/sdccman.lyx: renamed --disable-device-lib-build to
3067 --disable-device-lib, added --enable-doc, added section VPATH
3069 * sim/ucsim/configure.in,
3070 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
3071 z80 are enabled by default
3073 2006-04-24 Raphael Neider <rneider AT web.de>
3075 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
3076 to config word, "pic14_"-prefixed some extern functions
3077 (pic14_emitConfigWord): emit __config directive(s) if assignment to
3078 config word has been found
3079 * src/pic/device.h: added prototypes
3080 * src/pic/pcode.c: added "pic14_"-prefix where needed

3389 call to allocReg, not by manually allocating a new one,
3390 (pic16_assignRegisters): now before going through the register
3391 allocating functions mark all registers as free. This eliminates some
3392 side effects resulting from peephole parser done earlier in the backbone

3460 _main (this should take care the --main-return command line option in
3462 (genOr): removed some legacy pic-port instructions,
3463 * src/pic16/genarith.c (genAddLit): re-enabled old code because
3464 performing operations with SFR's causes data to be written more than
3465 once to each SFR. Perhaps SFRs should be handled in special cases...
3466 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
3468 * src/pic16/main.c (_process_pragma): stack bound checking did not take
3469 into account for stack starting position,
3470 (struct OPTIONS pic16_optionsTable): added command line argument
3471 --extended or -y for Extended Instruction Support,
3472 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
3473 (deassignLRs): *** perhaps the most important change, old 'for' code
3474 (commented out for reference), didn't account for some registers which
3475 were left marked 'not free' after a pointer operation. The change
3476 reduces register usage a lot in some cases

5751 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
5752 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
5753 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
5754 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
5755 always available in leading double underscore form. The C99 support is
5756 mostly missing, but it's a start.
5757 * support/regression/tests/bug-227710.c: fixed nonconforming use of
5758 reserved identifier "__data".

5836 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
5838 * device/lib/printf_large.c: removed inline assembly for portability and
5839 readability. Use printf_fast if speed or size are more important.
5840 * src/pic16/gen.c: removed conditions around use of DEBUGpc
5841 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
5843 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
5845 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
5846 prevent compiler warning
5848 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
5850 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
5851 moved to level 0 and declared as static. Also they are explicit
5852 placed in access bank. This was necessery because some times they
5853 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
5854 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
5855 optimizations. Currently only compare to unsigned char is implemented,
5856 * src/pic16/gen.c: added fReturnIdx array,
5857 * (struct resolvedIfx) is moved to gen.h and made public,
5858 * (struct _G): added sregsAlloc and sregsAllocSet fields,
5859 * (aopForSym): added an optimization to directly store in stack of
5860 the operand of a SEND iCode,
5861 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
5862 but as registers instead (AOP_REG) using the fReturnIdx array,
5863 * (pic16_freeAsmop): remove the freed register from the
5864 _G.sregsAlloc field,
5865 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
5866 a compare of 'WREG',
5867 * (pic16_popGetTempRegCond): changed function prototype, now
5868 function takes also a bitVector argument v which holds the current
5869 set of registers that are allocated for stack access by aopForSym,
5870 registers allocated in aopForSym for accessing stack symbols are not
5871 any more part of the functions usedRegs field,
5872 * (genCall): some times aopOp is called for a stack variable to be
5873 send, aopForSym might perform the push, if this is true make sure
5874 that genCall doesn't push the variable twice by testing _G.resDirect,
5875 * (genFunction): changed testing for unspecified interrupt number
5876 from 256 to INTNO_UNSPEC,
5877 * modified selection scheme of frame pointer generation. Previously
5878 if function did use local registers a frame pointer was generated,
5879 now a frame pointer is generated only if function has arguments
5880 (that need PLUSW2 register access), or has stack arguments, or the
5881 compiler is not instructed to omit the frame pointer,
5882 * (genEndFunction): before restoring local registers that were saved
5883 in the function preamble, also restore the registers that *might*
5884 have been allocated for stack access,
5885 * (genRet): removed some old comments,
5886 * (genCmp, the active (RN's) version): added a call to the
5887 pic16_genCmp_special function to perform the compare with a more
5888 robust and optimized way,
5889 * (genInline): a feature has been added in inline code generation,
5890 which allows a wildcard variable substitution when writing inline
5891 assembly. Code is incomplete and experimental therefore undocumented,
5892 * (genCast): changed order of aopOp for result and right to allow
5893 aopForSym to directly load the result if possible,
5894 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
5895 perform an optimized compare on some selected special occasions,
5896 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
5897 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
5898 generate an IVT any more,
5899 * src/pic16/main.c (pic16_optionsTable): added command line option
5901 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
5902 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
5904 * src/pic16/NOTES: Raphael Neider added in list of active developers
5905 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
5906 jumptable_end to prevent bug #,
5907 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
5908 inCond and outCond fields,
5909 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
5910 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
5911 turn off register spilling,
5912 * (packRegsForOneUse): synced with other ports' versions although it
5913 is not used currently,
5914 * (pic16_packRegisters): added an optimization while reading
5915 structure bitfields, some registers may be saved (malloc code is
5916 decreased by 80 bytes)
5918 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
5920 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
5921 left is a bitfield, if yes, then don't optimize assignment. Perhaps
5922 this can be optimized more?
5924 2005-03-10 Raphael Neider <rneider AT web.de>
5926 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
5927 genNearPointerGet): (hopefully) fixed access to bitfields via
5928 pointers (p->bitN = x; and x = p->bitN; failed)
5930 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

5973 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
5974 to keep the correct label reference count when adding/removing references
5975 to labels. A peephole file using this is appended to patch #1144962.
5977 2005-02-14 Raphael Neider <rneider AT web.de>

6562 Adding support for replacing ljmps with sjmps in jumptables
6563 generated for switch statements. For now you need to set the
6564 environment variable SDCC_SJMP_JUMPTABLE to enable this.
6565 Now 4 algorithms for mcs51 jumptable generation are used:
6566 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
6567 addresses loaded pc-relative for up to 112 cases and stack-pushing
6568 target addresses loaded with offset from dptr for up to 256 cases.

6598 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
6600 * added libc directory. The current version of LibC contains string
6601 functions, ctype functions and macros and some functions of the
6602 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
6603 be extensively tested in the future. Standard disclaimer here.
6604 Library is not automatically build yet. But one can build it by
6605 invoking 'make' inside the libc directory.

6616 * (pic16_storeForReturn): optimized return of 0,
6617 * (genCmp): experimental code for new genCmp which uses PIC18's
6618 special compare&skip instructions. Initial tests fail some times
6619 with variables grater than 1 byte in size, so new code is disabled,
6620 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
6622 * (genCast): began a fix to optimize the casting of a bit to another
6623 bit, now assigning a bitfield to another bitfield will fail, sorry,

6632 and 1 for banking instruction,
6633 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
6634 caused stop processing pCodes after a inline assembly block,
6635 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

6637 registers when it shouldn't,
6638 * src/pic16/ralloc.c (allocReg): add preliminary support for
6639 supporting a limited set of temporary registers,
6641 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6647 (genFunction): optimize RECEIVE iCodes in reentrant functions
6649 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9532 virus/worm forged address usage.
9534 2004-01-27 Bernhard Held <bernhard AT bernhardheld.de>
9536 Fixed promotion, it should be done on AST level:

9560 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
9562 * src/SDCCast.c: added an additional type flow in decorateType() of
9563 opposite direction, see feature request #860006; it's enabled at runtime
9564 by setting the environment variable SDCC_NEWTYPEFLOW
9565 * src/SDCCast.h: changed prototype of decorateType()
9566 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
9567 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
9568 'char' to 'int' can be omitted, if both operands are 'unsigned char';
9569 see feature request #877103

9599 added support for multiple code pages and multiple RAM banks on the
9600 PIC 14 port. The ASM files now no longer simply assume all the
9601 code / RAM are in the same page / bank. This means the linker can
9602 safely allocate code/RAM of separate ASM files to different pages/banks.
9603 * doc/sdccman.lyx: added Slade's tips
9604 * src/mcs51/peeph.def: fixed bug #880768

9646 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
9648 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
9649 loaded with the linker search paths (-L arguments) and the libraries
9650 to be linked with the current source (-l arguments). Changes
9651 currently will affect only the pic16 port.
9652 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
9653 include path the port specific paths and port specific libraries,
9654 * gplink command now contains the $3 argument,
9655 * src/pic16/device.h,
9656 * src/pic16/device.c,: structure PIC_device is made public and
9657 renamed to PIC16_device, the same for variable Pics which is renamed

9672 Documenting changes from previous commits.
9673 * configure.in (version 1.56),
9674 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
9675 when generating output files to configure the pic16 library,
9676 but now I've commented it out, since gputils aren't installed in the
9677 SF compile farm, so library won't compile
9679 * device/lib/Makefile.in (version 1.56): initially I've added in
9680 target 'all' the prerequestive 'model-pic16' so it compiled the
9681 pic16 library, but now I've commented it out for the same reasons
9683 * added targets 'model-pic16' and 'objects-pic16' to compile the
9685 * added target 'port-specific-objects-pic16' to handle the
9686 generated libraries and copy them into the build/ directory
9687 * added target 'clean-intermediate-pic16' to clean intermediate
9688 files into pic16 directory
9689 * in target 'installdirs' added line to create directory pic16 in
9690 the installation path

9693 added lines to copy all header files to installation path,
9694 * in target 'installdirs' added line create directory for pic16
9695 headers in the installation path

9710 * src/z80/main.c (_parseOptions): fixed the portmode= command line
9711 option so that it actually works. Made it specific to the z80, since
9712 the gbz80 doesn't have these kinds of I/O ports.
9714 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9716 * device/include/z180.h,

9740 via literal number. The symbol is placed in the corresponding
9741 position of the data ram
9742 * (pic16_dump_section): relocatable and absolute uninitialized
9743 data are now emitted in sorted order to reduce section naming,
9744 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
9745 weren't marked as being in the access bank,
9747 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
9749 Added portion of GNU PIC Library under the directory
9750 device/include/pic16 and device/lib/pic16. These files
9751 contain the declarations of SFRs for the PIC18Fxx2 devices.
9752 The directory is initialized via configure from toplevel.

9782 all over. Telling LaTeX to be less strict with word spacing
9783 to better keep the right margin. Changed some notes about
9784 maintainance of the ports in section 3.2.1 - is it OK like this?

9980 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9982 PIC16 port related changes:
9983 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
9984 added variable stackPos,
9986 * gen.c: genCall, assignResultValue: added support for
9987 pushing/retrieving function parameters to/from stack,
9988 genFunction,genEndFunction: setup stack frame for the
9990 genAddrOf: will be changed according to bug 863624
9992 * added files genutils.c and genutils.h which contain gen*
9993 debugged and optimised functions extracted from gen.c
9995 * glue.c: added variable 'externs' which holds extern symbols,
9996 pic16emitRegularMap: is modified to properly handle relocatable
9997 symbols under the new scheme,
9998 pic16createInterruptVect: is modified
9999 pic16printPublics: is modified to emit 'global' assembler directives,
10000 added pic16_printExterns to print extern symbols,
10001 pic16glue: initializes stack/frame pointer in the beginning of
10002 the assembly output. Temporary hack, will be corrected later,
10003 because gplink yet does not support stack and SDCC does not
10004 yet support a type of crt0.o object to create the final binary.
10006 * Removed many lines that contain 8051 legacy code.
10007 * The code is finally placed under a 'code' directive.
10008 * Added port specific options.
10010 * _process_pragma: simplified since now we do not need *special*
10011 include file to define SFR registers. But a separate header
10012 will be needed. This will be developed later.
10013 * _pic16_parseOptions: added, parses port specific options:
10014 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
10015 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
10016 --preplace-udata-with=
10018 * _pic16_setDefaultOptions: modified to initialize section names,
10019 but hack is temporarly out of order since it needs improvement.
10020 * _pic16_genAssemblerPreamble: configuration words are emitted by
10021 their address instead of their name. This part is incomplete and
10022 supports only the 18Fxx2 devices. Other devices will emit an error
10023 during assembly since they do not contain the same set of config
10025 * _pic16_genIVT: is modified,
10027 * pcode.c: added definitions for some hardware registers that are needed
10029 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
10030 All PCI entries are updated. Now LFSR is supported.
10031 * Removed pic16_pciTRIS is mentioned by mdubuc in source
10032 * added pic16_newpCodeOpLit2 to support instructions with
10033 two literal arguments
10034 * pic16_pCode2str: corrected code that emits assembler instructions
10035 with two literal operands and those that have an access bit modifier
10036 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
10037 this fixes a bug which caused some labels to be lost, when an
10038 assembler directive was added, i.e. banksel,
10039 * pic16_FixRegisterBanking: improved logic that causes the insertion
10041 * InlineFunction: functions that are called once, are not any more
10042 inlined. This can be a port option in the future,
10044 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
10046 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
10047 hold the corresponding uninitialized symbols,
10048 * pic16_allocProcessorRegister: registers have explicit marked the
10050 * pic16_allocInternalRegister: registers are explicit marked as
10052 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
10053 processing list, so bit registers were lost,
10056 * ralloc.h: added field 'accessBank' and original symbol operand
10057 in register definition,
10058 * removed the field isMapped from register definition,
10060 ** Several functions have been removed from various sources:
10061 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
10062 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
10063 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
10064 pic16_assignRelocatableRegisters
10066 ** others have been introduced:
10067 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
10068 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
10070 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
10072 * support/scripts/inc2h.pl: changed definition of BIT_AT
10073 to emit 'sbit at' instead of 'bit at'. This was a request.
10075 PIC16 port related preliminary changes:
10076 * gen.c: prefixed function popRegFromString with
10077 pic16_ and all references to it corrected
10078 * pcode.c: all pic16_pc_* hardware registers prefixed
10079 with underscore (_),
10080 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
10081 * ralloc.c: newReg(): when register is REG_SFR then
10082 set address to rIdx,
10083 pic16_allocProcessorRegister(): marks register wasUsed=0
10084 pic16_writeUsedRegs(): added a call to assign processor
10085 registers via pic16_assignFixedRegisters
10087 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10089 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
10090 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
10091 variables in unused register banks. Also the SSEG is placed
10092 wherever there is enough space for it, and IDATA can be anywhere
10093 in internal RAM. For now compile using -Wl-Y[stack_size].
10094 The mem file is different for this option as well, since it
10095 makes no sense of talking about DSEG lenght.
10097 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
10099 * src/SDCClrange.c: fixed bug 869095 that caused segfault
10100 in certain cases, e.g. when ROM assignment, patch provided
10101 from Albert den Haan.

10344 * src/SDCCast.c (decorateType): disabled a transformation I added in
10345 revision 1.188 (access to fields of a structure at an absolute address);
10346 it breaks with bitfields, extern declarations, and gcse analysis.
10347 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
10348 could be assigned through a pointer, so don't complain.
10349 * src/SDCCast.c (astErrors),

10969 * src/ds390/gen.c (genFunction, genEndFunction): Moved save
10970 and restore of EA so that stack offsets to parameters are
10971 correct when using both critical and reentrant/stack-auto.
10972 * src/z80/gen.c (aopOp): removed erroneous assertion about sloc
10973 size (can be triggered in error if sloc is shared between
10974 different sized objects)
10975 * device/include/float.h: fixed macros to explicitly use
10976 unsigned long where needed
10978 2003-09-15 Bernhard Held <bernhard AT bernhardheld.de>

10986 * src/SDCCsymt.c (sclsFromPtr),
10988 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
10989 support for standard C idiom of memory mapped variables; for
10990 example, *((xdata int*)0x1234) = 1 is now internally equivalent
10991 to xdata int at 0x1234 tempvar = 1.
10992 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch

11009 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11011 Fixed bug #621531 (const & volatile confusion in the type chain).
11012 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
11013 refer to the const or volatile state of the pointer itself.
11025 * src/pic16/ralloc.c
11026 * support/regression/tests/const.c
11028 2003-09-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11030 When checking for duplicated modules, use absolute paths
11031 instead of relative paths. Files changed:

11078 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
11079 pcoderegs.h, ralloc.c, ralloc.h
11080 * main.c: added top header and GPL license notice

11083 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
11085 * device/lib/_mullong.c: replaced int by short for gcc
11087 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11089 * src/SDCCpeeph.c (notVolatile, notVolatileVariable): handle IFX
11090 and JUMPTABLE iCodes properly now (worked by accident before)
11091 * src/mcs51/gen.c (leftRightUseAcc),
11092 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
11093 iCode properly now. Use getSize instead of nRegs since a & b
11094 aren't part of the nRegs tally.
11096 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
11098 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

11104 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
11105 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
11106 fetching of the pointer
11107 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
11108 copied from genNearPointerSet()
11109 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
11110 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
11111 If they pop r0/r1 they must be called in the opposite order than aopOp().
11112 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
11113 (resp. --stack-auto), prepared for --xstack
11115 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11117 * doc/sdccman.lyx: reverted tables to those in cvs 1.64
11119 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11121 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
11122 these ports have their own __sdcc_external_start()
11124 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
11126 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11127 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
11128 type for bits was changed. It resulted in bit variables becoming
11129 global, which is not permitted in PIC 14 assembly output.
11131 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11133 * doc/sdccman.lyx: various additions and updates. Rearranged sections
11135 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11137 Z80 and MCS51 linkers complaint if a public symbol is defined
11138 in more than one library module:

11144 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11146 A few small changes that speed up the peephole optimizer.
11150 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11152 Try to make the peephole optimizer smarter by maintaining
11153 an association between the assembly source code and the
11154 iCodes that originated them. Put this information to use
11155 with a new peephole rule condition "notVolatile" so that
11156 the rules can be aggressive yet still safe.
11161 * src/mcs51/peeph.def
11163 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11167 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
11168 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
11169 if the left or right operand symbols have the accuse flag set.
11171 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11173 Changed the type of the result of the ! (NOT) operator to char;
11174 previously it returned the same type as the source. This allows
11175 us to eliminate all the genFloatNot functions (all of its target
11176 implementations were very buggy) since !float can use the same
11179 * src/SDCCicode.c (ast2iCode): ! returns char
11180 * src/mcs51/gen.c (genNot, genNotFloat),
11181 * src/ds390/gen.c (genNot, genNotFloat),
11182 * src/z80/gen.c (genNot, genNotFloat),
11183 * src/pic/gen.c (genNot, genNotFloat),
11184 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

11188 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11189 1. Interrupt would not compile properly. Ensure PCLATH register is saved
11190 during interrupts. Ensure WSAVE is located at a shared bank address.
11191 2. Fixed page selection in some places
11192 3. Fixed BTFSS/C to where necessary use registers directly and not simply
11193 the registers name strings.
11194 4. Fixed "signed / unsigned compare" compiler warnings.
11195 5. The PIC port manages its own allocation of the general purpose
11196 registers, but makes no attempt to reuse them. As a result when
11197 compiling it soon runs out of general purpose registers. Some
11198 additional code was added to the files pcode.c and device.c to walk
11199 through the function call tree and rename the registers so that they
11209 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
11210 genPlus() & genMinus() when the result is the same as left or right
11212 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11214 * src/z80/gen.c (isUnsplitable, fetchPairLong): fixed bug #770454
11216 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11218 Made bitfield a distinct type from bit so that bitfields
11219 convert as per ANSI C and bits retain their traditional
11220 boolean style behaviour. Implemented bitfield support in
11228 * src/ds390/gen.c: bit v bitfield split
11229 * src/z80/gen.c: New support for bitfields
11230 * support/regression/tests/bitfields.c: reenabled z80,
11233 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11235 Rules 246.x, 247.x relate to bitfields, the others speed up
11236 access to xdata mapped I/O devices.
11238 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
11240 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11242 Cleaned up genPackBits and genUnpackBits and added two helper
11243 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
11244 for literal assignments in genPackBits (thanks to Frieder for
11250 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11252 Fixed bug #748310 (pointer to function type mishandled when the
11253 function name is omitted). Also fixed a SIGSEGV when a function
11254 attribute (reentrant, etc) is used on a non-function or on a
11255 function but misplaced before the parameter list.
11257 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
11259 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
11260 * support/Util/SDCCerr.h,
11261 * support/Util/SDCCerr.c: Added func attr misuse error msg
11263 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
11265 Fixed bug #787649 by anonymous
11266 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
11267 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
11269 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11271 Fixed numerous bitfield problems.
11273 * src/SDCC.y: More bitfield related error checking

11276 * support/Util/SDCCerr.h,
11277 * support/Util/SDCCerr.c: Added & edited some bitfield err msgs
11278 * src/mcs51/gen.c (genPackBits, genUnpackBits): fixed mask bugs
11279 * src/ds390/gen.c (genPackBits, genUnpackBits): fixed mask bugs
11280 * support/regression/tests/bitfields.c: tests added
11282 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11284 Made the constant following the "interrupt" keyword optional. If
11285 omitted, the function will not automatically be given an entry
11286 in the interrupt vector table (similar to #pragma NOIV, but
11287 less syntacticly kludgy). The interrupt number is also now
11288 range checked. Also fixed a bug in the high order bit example

11296 * support/Util/SDCCerr.h
11299 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
11301 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
11302 * src/SDCCicode.c (operandOperation): rewritten some ops
11303 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
11304 * src/SDCCsymt.c (computeType): literals are handled the same way as any
11306 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
11307 be re-activated by defining REDUCE_LITERALS)
11308 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
11309 unsigned, but are signed by default
11310 * src/SDCCval.c (constVal): rearranged
11311 * src/SDCCval.c (valMod): preliminary fix
11312 * src/SDCCval.c (valCastLiteral): use TYPE_* types

11352 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
11353 * src/SDCCval.c (constVal): changed default to signed; hex and octal
11354 constants are unsigned; added recognition of "u" flag for unsigned
11355 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
11356 * src/SDCCval.c (valDiv, valMod): fixed signdness

11820 support for the PIc16 port in the ports table, when executing
11821 the compiler with no port specified on command line, a default
11822 port is selected with the new macro DEFAULT_PORT which is
11823 defined in port.h, in setDefaultOptions() linkOptions is removed
11824 from initialization assignment, since now it is a set,
11825 parseCmdLine uses setParseWithComma for linkOptions, in
11826 linkEdit() linkOptions are accessed with new function indexSet()
11827 which returns the i'th item of a set variable. See SDCCset.c, in
11828 linkEdit() when calling buildCmdLine(), added linkOptions as
11829 last argument. Now users can pass arguments to gplink via the

11844 gpasm complaining and test the linkage with gplink, _linkCmd and
11845 _asmCmd changed to be more gplink and gpasm friendly
11846 * src/pic16/peeph.def: peep rule 3 is commented out, since it
11847 produced an error when parsed, peep rule 12 is added to utilize
11848 movff, but it is commented out since the pCode does not support
11849 yet a command with 2 address arguments

12888 * src/SDCCicode.c: fixed array add
12890 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
12891 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
12892 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
12894 2003-01-04 <johan AT balder>

12898 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12899 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
12901 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
12902 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

12908 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
12909 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
12911 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
12912 * src/mcs51/main.c: removed {bindir}{sep} from aslink
12914 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12916 * in /sdcc/as/mcs51/ changed these files in order to create an
12917 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
12918 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
12919 following files to include the previous two files: aslink.dsp,
12920 Makefile.aslink, Makefile.bcc, and Makefile.in.
12922 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
12923 .adb instead of .cdb
12925 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12927 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
12928 value from option --iram-size.
12930 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12932 * /sdcc/as/mcs51/lklist.c: added boundary check before using
12935 2002-09-18 <wiml AT hhhh.org>
12937 * SDCClrange.h: exposed setFromRange() and setToRange()
12938 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
12939 packRegsForAccUse() (bug 542397)
12940 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
12941 multiple times and emitting the fetch operations more than once
12942 added aopGetUsesAcc() function to allow binary operators to
12943 fetch their operands in the correct order; made genMinus() emit
12944 compact code for X = LITERAL - Y
12946 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12947 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
12948 sprintf() in line 1267.
12950 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12951 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
12954 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12955 Changes to aslink (All the changes are marked with 'JCF'):
12957 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
12960 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
12961 area BSEG. Also moves, if possible, the DATA area down into the internal
12962 ram so more space is available.
12964 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
12967 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
12968 not bytes. Function summary() which creates a memory usage summary
12969 file with extension .mem. Reports of overlaping stack and small stack
12970 size. If the space for the stack is less than 16 bytes aslink trows a
12973 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
12974 the 8051. Option 'y' for memory summary output file.
12976 Changes to sdcc (All the changes are marked with 'JCF'):
12978 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
12980 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
12981 overlaying area for it (uses RegBankUsed[4]).
12983 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
12984 bank zero as used by default. By default aslink locates the stack
12985 (equivalent to --stack-after-data). Pass option 'y' to aslink for
12986 the creation of the .mem file. Delegates the allocation of data area
12987 to aslink (it is not longer 0x30 by default). If --stack-loc passes
12988 the begining of the stack area to aslink.
12990 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
12991 glue() in SDCCglue.c creates an area for it.
12993 2002-09-03 Borut Razem <borut.razem AT siol.net>
12994 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12995 sdcc/src/pic/glue.c:
12996 introduced atexit() handler for teporay files removal in case of
12997 errors, assertions, ...
12999 2002-08-29 Borut Razem <borut.razem AT siol.net>
13000 * sdcc/support/cpp2/auto-host_vc_in.h:
13001 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
13002 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
13003 Maybe there is a similar problem with BORLANDC? It should be checked!
13005 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
13006 corrected improper use of assert: the assignment to clr variable was done inside the assert.
13007 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
13008 was not executed, and the compiler (cl) launched a warning:
13009 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
13011 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
13012 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
13014 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
13015 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
13017 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
13018 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
13019 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
13020 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
13021 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
13022 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
13023 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
13024 - added Release configuration in VS projects
13025 - review of compiler an linker options
13026 - VC .exe files are generated in bin_vc directory, not to interfere
13027 with binaries generated from other projects (cygwin, mingw, bcc ...)
13029 * sdcc/src/yacc.dsp: added
13031 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
13032 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
13033 and insert the version number definitions from .version
13035 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
13037 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
13038 added - genarate auto-host.h using auto-host_vc_in.h as template
13041 removed from CVS, generated automatically
13043 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
13044 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
13046 2002-08-11 Borut Razem <borut.razem AT siol.net>
13047 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
13049 2002-08-10 Borut Razem <borut.razem AT siol.net>
13050 * src/SDCCmain.c (main):
13051 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
13052 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
13053 The consequence was that some temporary files were not removed.
13056 unification of code in functions tempfilename() and tempfile():
13057 function tempnam() is defined in Visual Studio 6.0 and .NET
13059 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
13061 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
13062 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
13063 - removed compiler command line option /WX: Treats all warnings as errors
13064 - update a list of source files, included into the project
13066 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
13067 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
13068 changed project type to Generic Project so that can be correcly converted to VS.NET project
13070 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
13072 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
13074 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
13076 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
13077 added return 0 statements after assert() to make compiler happy
13079 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
13080 added newline in the def file to keep MSC compiler satisfied
13082 * sdcc/src/z80/gen.c:
13083 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
13084 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
13085 - solved MSC error in function aopDump()
13087 * sdcc_vc.h: define PREFIX as "\\sdcc"
13089 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
13090 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

13129 2002-03-28 Johan Knol <johan AT balder>
13131 * src/SDCCval.c: fixed bug #532436
13133 2002-03-14 Scott Dattalo <scott AT dattalo.com>
13135 Added "char *Processor" field to the port structure.
13138 Added -p option. Allows port dependent processor to be specified.
13141 Initialized the new field char *Processor field to NULL in all ports
13144 Compiler generated registers for interrupt context saving
13145 were not getting allocated.
13147 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
13150 Fixed left shift. Will promote the left side of a left shift
13151 if a) left shifting more than size of operand or b) when assigned
13152 to something size > size of left side
13154 2002-03-14 Scott Dattalo <scott AT dattalo.com>

13264 * sdcc/src/SDCCloop.c:
13265 Previous fix was not good. basic blocks that have "break" or "return" are
13266 not really partof a loop , but live ranges used in these blocks should
13267 be live thru the entire loop, so set partOfLoop but don't add them to
