1411 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>
1413 * src/pic/pcode.c (PCodeID): commented out left over debug code
1415 2004-01-20 Bernhard Held <bernhard AT bernhardheld.de>
1417 * support/valdiag/tests/overflow.c: added shift tests
1425 * src/pic/pcodepeep.c,
1426 * src/pic/pcoderegs.c,
1428 * src/pic/ralloc.h: applied patch from Slade Rich;
1429 added support for multiple code pages and multiple RAM banks on the
1430 PIC 14 port. The ASM files now no longer simply assume all the
1431 code / RAM are in the same page / bank. This means the linker can
1432 safely allocate code/RAM of separate ASM files to different pages/banks.
1433 * doc/sdccman.lyx: added Slade's tips
1434 * src/mcs51/peeph.def: fixed bug #880768

1443 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
1446 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
1447 strtof is not part of C89 and isn't included with Mac OS X.
1449 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1451 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

1460 2004-01-19 Bernhard Held <bernhard AT bernhardheld.de>
1462 * src/SDCCicode.c (geniCodeArray): applied patch from Stas Sergeev
1463 proposed in FR #877103
1465 2004-01-18 Bernhard Held <bernhard AT bernhardheld.de>
1467 * src/SDCCval.c (cheapestVal): added missing checks

1476 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
1478 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
1479 loaded with the linker search paths (-L arguments) and the libraries
1480 to be linked with the current source (-l arguments). Changes
1481 currently will affect only the pic16 port.
1482 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
1483 include path the port specific paths and port specific libraries,
1484 * gplink command now contains the $3 argument,
1485 * src/pic16/device.h,
1486 * src/pic16/device.c,: structure PIC_device is made public and
1487 renamed to PIC16_device, the same for variable Pics which is renamed
1488 to Pics16. Updated all references to them.
1489 * src/pic16/glue.c (pic16glue): corrected bug with code
1490 initialization which bypassed the variable initializations block.
1492 * device/lib/pic16/Makefile.rules: removed --penable-stack from
1493 COMPILE_FLAGS and added the --nostdinc option
1495 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

1500 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
1502 Documenting changes from previous commits.
1503 * configure.in (version 1.56),
1504 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
1505 when generating output files to configure the pic16 library,
1506 but now I've commented it out, since gputils aren't installed in the
1507 SF compile farm, so library won't compile
1509 * device/lib/Makefile.in (version 1.56): initially I've added in
1510 target 'all' the prerequestive 'model-pic16' so it compiled the
1511 pic16 library, but now I've commented it out for the same reasons
1513 * added targets 'model-pic16' and 'objects-pic16' to compile the
1515 * added target 'port-specific-objects-pic16' to handle the
1516 generated libraries and copy them into the build/ directory
1517 * added target 'clean-intermediate-pic16' to clean intermediate
1518 files into pic16 directory
1519 * in target 'installdirs' added line to create directory pic16 in
1520 the installation path
1522 * device/include/Makefile.in (version 1.11): in target 'install'
1523 added lines to copy all header files to installation path,
1524 * in target 'installdirs' added line create directory for pic16
1525 headers in the installation path

1540 * src/z80/main.c (_parseOptions): fixed the portmode= command line
1541 option so that it actually works. Made it specific to the z80, since
1542 the gbz80 doesn't have these kinds of I/O ports.
1544 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1546 * device/include/z180.h,

1568 Mainly changes to support compilation of the device libraries
1569 * src/pic16/device.c: stack is allocated via symbol and not
1570 via literal number. The symbol is placed in the corresponding
1571 position of the data ram
1572 * (pic16_dump_section): relocatable and absolute uninitialized
1573 data are now emitted in sorted order to reduce section naming,
1574 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
1575 weren't marked as being in the access bank,
1577 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
1579 Added portion of GNU PIC Library under the directory
1580 device/include/pic16 and device/lib/pic16. These files
1581 contain the declarations of SFRs for the PIC18Fxx2 devices.
1582 The directory is initialized via configure from toplevel.
1584 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
1586 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

1612 all over. Telling LaTeX to be less strict with word spacing
1613 to better keep the right margin. Changed some notes about
1614 maintainance of the ports in section 3.2.1 - is it OK like this?
1616 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

1654 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
1656 * src/pic16/peeph.def: all peepholes with movff are commented out,
1657 because there is a problem in the pcode peep optimizer,
1658 * src/pic16/ralloc.c: the register allocator can now reuse local

1810 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
1812 PIC16 port related changes:
1813 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
1814 added variable stackPos,
1816 * gen.c: genCall, assignResultValue: added support for
1817 pushing/retrieving function parameters to/from stack,
1818 genFunction,genEndFunction: setup stack frame for the
1820 genAddrOf: will be changed according to bug 863624
1822 * added files genutils.c and genutils.h which contain gen*
1823 debugged and optimised functions extracted from gen.c
1825 * glue.c: added variable 'externs' which holds extern symbols,
1826 pic16emitRegularMap: is modified to properly handle relocatable
1827 symbols under the new scheme,
1828 pic16createInterruptVect: is modified
1829 pic16printPublics: is modified to emit 'global' assembler directives,
1830 added pic16_printExterns to print extern symbols,
1831 pic16glue: initializes stack/frame pointer in the beginning of
1832 the assembly output. Temporary hack, will be corrected later,
1833 because gplink yet does not support stack and SDCC does not
1834 yet support a type of crt0.o object to create the final binary.
1836 * Removed many lines that contain 8051 legacy code.
1837 * The code is finally placed under a 'code' directive.
1838 * Added port specific options.
1840 * _process_pragma: simplified since now we do not need *special*
1841 include file to define SFR registers. But a separate header
1842 will be needed. This will be developed later.
1843 * _pic16_parseOptions: added, parses port specific options:
1844 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
1845 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
1846 --preplace-udata-with=
1848 * _pic16_setDefaultOptions: modified to initialize section names,
1849 but hack is temporarly out of order since it needs improvement.
1850 * _pic16_genAssemblerPreamble: configuration words are emitted by
1851 their address instead of their name. This part is incomplete and
1852 supports only the 18Fxx2 devices. Other devices will emit an error
1853 during assembly since they do not contain the same set of config
1855 * _pic16_genIVT: is modified,
1857 * pcode.c: added definitions for some hardware registers that are needed
1859 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
1860 All PCI entries are updated. Now LFSR is supported.
1861 * Removed pic16_pciTRIS is mentioned by mdubuc in source
1862 * added pic16_newpCodeOpLit2 to support instructions with
1863 two literal arguments
1864 * pic16_pCode2str: corrected code that emits assembler instructions
1865 with two literal operands and those that have an access bit modifier
1866 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
1867 this fixes a bug which caused some labels to be lost, when an
1868 assembler directive was added, i.e. banksel,
1869 * pic16_FixRegisterBanking: improved logic that causes the insertion
1871 * InlineFunction: functions that are called once, are not any more
1872 inlined. This can be a port option in the future,
1874 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
1876 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
1877 hold the corresponding uninitialized symbols,
1878 * pic16_allocProcessorRegister: registers have explicit marked the
1880 * pic16_allocInternalRegister: registers are explicit marked as
1882 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
1883 processing list, so bit registers were lost,
1886 * ralloc.h: added field 'accessBank' and original symbol operand
1887 in register definition,
1888 * removed the field isMapped from register definition,
1890 ** Several functions have been removed from various sources:
1891 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
1892 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
1893 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
1894 pic16_assignRelocatableRegisters
1896 ** others have been introduced:
1897 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
1898 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
1900 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
1902 * support/scripts/inc2h.pl: changed definition of BIT_AT
1903 to emit 'sbit at' instead of 'bit at'. This was a request.
1905 PIC16 port related preliminary changes:
1906 * gen.c: prefixed function popRegFromString with
1907 pic16_ and all references to it corrected
1908 * pcode.c: all pic16_pc_* hardware registers prefixed
1909 with underscore (_),
1910 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
1911 * ralloc.c: newReg(): when register is REG_SFR then
1912 set address to rIdx,
1913 pic16_allocProcessorRegister(): marks register wasUsed=0
1914 pic16_writeUsedRegs(): added a call to assign processor
1915 registers via pic16_assignFixedRegisters
1917 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
1919 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
1920 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
1921 variables in unused register banks. Also the SSEG is placed
1922 wherever there is enough space for it, and IDATA can be anywhere
1923 in internal RAM. For now compile using -Wl-Y[stack_size].
1924 The mem file is different for this option as well, since it
1925 makes no sense of talking about DSEG lenght.
1927 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
1929 * src/SDCClrange.c: fixed bug 869095 that caused segfault

2176 it breaks with bitfields, extern declarations, and gcse analysis.
2177 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it

2904 2003-09-04 Vangelis Rokas <vrokas AT otenet.gr>
2906 * Top header beautifications in src/pic16 directory:
2907 device.c, device.h, gen.c, gen.h, genarith.c, glue.c, pcode.c,
2908 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
2909 pcoderegs.h, ralloc.c, ralloc.h
2910 * main.c: added top header and GPL license notice
2911 * pcode.c: fixed the if-conditional warning
2913 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
2915 * device/lib/_mullong.c: replaced int by short for gcc
2917 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2919 * src/SDCCpeeph.c (notVolatile, notVolatileVariable): handle IFX
2920 and JUMPTABLE iCodes properly now (worked by accident before)
2921 * src/mcs51/gen.c (leftRightUseAcc),
2922 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
2923 iCode properly now. Use getSize instead of nRegs since a & b
2924 aren't part of the nRegs tally.
2926 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
2928 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()
2929 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
2930 before instructions that use the _STATUS register
2932 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
2934 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
2935 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
2936 fetching of the pointer
2937 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
2938 copied from genNearPointerSet()
2939 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
2940 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
2941 If they pop r0/r1 they must be called in the opposite order than aopOp().
2942 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
2943 (resp. --stack-auto), prepared for --xstack
2945 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

2949 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
2951 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
2952 these ports have their own __sdcc_external_start()
2954 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
2956 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
2957 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
2958 type for bits was changed. It resulted in bit variables becoming
2959 global, which is not permitted in PIC 14 assembly output.
2961 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
2963 * doc/sdccman.lyx: various additions and updates. Rearranged sections
2965 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2967 Z80 and MCS51 linkers complaint if a public symbol is defined
2968 in more than one library module:
2972 * as/mcs51/Makefile.in
2974 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2976 A few small changes that speed up the peephole optimizer.
2980 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2982 Try to make the peephole optimizer smarter by maintaining
2983 an association between the assembly source code and the
2984 iCodes that originated them. Put this information to use
2985 with a new peephole rule condition "notVolatile" so that
2986 the rules can be aggressive yet still safe.
2991 * src/mcs51/peeph.def
2993 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2997 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
2998 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
2999 if the left or right operand symbols have the accuse flag set.
3001 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3003 Changed the type of the result of the ! (NOT) operator to char;
3004 previously it returned the same type as the source. This allows
3005 us to eliminate all the genFloatNot functions (all of its target
3006 implementations were very buggy) since !float can use the same
3009 * src/SDCCicode.c (ast2iCode): ! returns char
3010 * src/mcs51/gen.c (genNot, genNotFloat),
3011 * src/ds390/gen.c (genNot, genNotFloat),
3012 * src/z80/gen.c (genNot, genNotFloat),
3013 * src/pic/gen.c (genNot, genNotFloat),
3014 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
3016 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
3018 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3019 1. Interrupt would not compile properly. Ensure PCLATH register is saved
3020 during interrupts. Ensure WSAVE is located at a shared bank address.
3021 2. Fixed page selection in some places
3022 3. Fixed BTFSS/C to where necessary use registers directly and not simply
3023 the registers name strings.
3024 4. Fixed "signed / unsigned compare" compiler warnings.
3025 5. The PIC port manages its own allocation of the general purpose
3026 registers, but makes no attempt to reuse them. As a result when
3027 compiling it soon runs out of general purpose registers. Some
3028 additional code was added to the files pcode.c and device.c to walk
3029 through the function call tree and rename the registers so that they
3039 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
3040 genPlus() & genMinus() when the result is the same as left or right
3042 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3046 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3048 Made bitfield a distinct type from bit so that bitfields
3049 convert as per ANSI C and bits retain their traditional
3050 boolean style behaviour. Implemented bitfield support in
3058 * src/ds390/gen.c: bit v bitfield split
3059 * src/z80/gen.c: New support for bitfields
3060 * support/regression/tests/bitfields.c: reenabled z80,
3063 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3065 Rules 246.x, 247.x relate to bitfields, the others speed up
3066 access to xdata mapped I/O devices.
3068 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
3070 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3072 Cleaned up genPackBits and genUnpackBits and added two helper
3073 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
3074 for literal assignments in genPackBits (thanks to Frieder for
3080 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3082 Fixed bug #748310 (pointer to function type mishandled when the
3083 function name is omitted). Also fixed a SIGSEGV when a function
3084 attribute (reentrant, etc) is used on a non-function or on a
3085 function but misplaced before the parameter list.
3087 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
3089 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
3090 * support/Util/SDCCerr.h,
3091 * support/Util/SDCCerr.c: Added func attr misuse error msg
3093 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
3095 Fixed bug #787649 by anonymous
3096 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr

3112 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3114 Made the constant following the "interrupt" keyword optional. If
3115 omitted, the function will not automatically be given an entry
3116 in the interrupt vector table (similar to #pragma NOIV, but
3117 less syntacticly kludgy). The interrupt number is also now
3118 range checked. Also fixed a bug in the high order bit example
3125 * support/Util/SDCCerr.c
3126 * support/Util/SDCCerr.h
3129 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

3132 * src/SDCCicode.c (operandOperation): rewritten some ops
3133 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
3134 * src/SDCCsymt.c (computeType): literals are handled the same way as any
3136 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
3137 be re-activated by defining REDUCE_LITERALS)
3138 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
3139 unsigned, but are signed by default
3140 * src/SDCCval.c (constVal): rearranged
3141 * src/SDCCval.c (valMod): preliminary fix
3142 * src/SDCCval.c (valCastLiteral): use TYPE_* types

3185 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
3186 * src/SDCCval.c (valDiv, valMod): fixed signdness
3187 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
3188 signedness of modulo, left and right shift

3594 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
3595 the regression tests I'm not brave enough to enable 245.b, 245.c
3596 * doc/sdccman.lyx: added latex preamble for hyperref package.
3597 Using pdflatex this will give you a hyperlinked pdf file with
3598 bookmarks. (prepend '%' before /usepackage if this breaks something)

3639 it can be defined with CFLAGS when running configure
3640 * src/SDCCmain.c: fixed compiling + linking with object files
3642 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

3645 added --disable-pic16-port
3646 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
3647 * src/SDCCmain.c: linkOptions is changed to set *,
3648 added if/endif conditional macros to remove options help
3649 messages from optionsTable when a port is not configured, added
3650 support for the PIc16 port in the ports table, when executing
3651 the compiler with no port specified on command line, a default
3652 port is selected with the new macro DEFAULT_PORT which is
3653 defined in port.h, in setDefaultOptions() linkOptions is removed
3654 from initialization assignment, since now it is a set,
3655 parseCmdLine uses setParseWithComma for linkOptions, in
3656 linkEdit() linkOptions are accessed with new function indexSet()
3657 which returns the i'th item of a set variable. See SDCCset.c, in
3658 linkEdit() when calling buildCmdLine(), added linkOptions as
3659 last argument. Now users can pass arguments to gplink via the
3660 -Wl option, main() uses pic16glue() to glue up pic16 programs

3672 * src/pic16/glue.c: commented out some error producing lines
3673 * src/pic16/main.c: __config directives are commented out to stop
3674 gpasm complaining and test the linkage with gplink, _linkCmd and
3675 _asmCmd changed to be more gplink and gpasm friendly
3676 * src/pic16/peeph.def: peep rule 3 is commented out, since it
3677 produced an error when parsed, peep rule 12 is added to utilize
3678 movff, but it is commented out since the pCode does not support
3679 yet a command with 2 address arguments
3681 2003-05-18 <johan AT balder>
3683 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

3710 2003-05-11 Borut Razem <borut.razem AT siol.net>
3712 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
3713 the path of bin directory, so that PATH is the only env. variable, which has to be set
3714 in case of standard installation.

4747 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
4748 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
4749 following files to include the previous two files: aslink.dsp,
4750 Makefile.aslink, Makefile.bcc, and Makefile.in.
4752 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
4753 .adb instead of .cdb
4755 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4757 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
4758 value from option --iram-size.
4760 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4762 * \sdcc\as\mcs51\lklist.c: added boundary check before using
4765 2002-09-18 <wiml AT hhhh.org>
4767 * SDCClrange.h: exposed setFromRange() and setToRange()
4768 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
4769 packRegsForAccUse() (bug 542397)
4770 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
4771 multiple times and emitting the fetch operations more than once
4772 added aopGetUsesAcc() function to allow binary operators to
4773 fetch their operands in the correct order; made genMinus() emit
4774 compact code for X = LITERAL - Y
4776 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4777 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to

4784 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4785 Changes to aslink (All the changes are marked with 'JCF'):
4787 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
4790 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
4791 area BSEG. Also moves, if possible, the DATA area down into the internal
4792 ram so more space is available.
4794 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
4797 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
4798 not bytes. Function summary() which creates a memory usage summary
4799 file with extension .mem. Reports of overlaping stack and small stack
4800 size. If the space for the stack is less than 16 bytes aslink trows a
4803 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
4804 the 8051. Option 'y' for memory summary output file.
4806 Changes to sdcc (All the changes are marked with 'JCF'):
4808 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
4810 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
4811 overlaying area for it (uses RegBankUsed[4]).
4813 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
4814 bank zero as used by default. By default aslink locates the stack
4815 (equivalent to --stack-after-data). Pass option 'y' to aslink for
4816 the creation of the .mem file. Delegates the allocation of data area
4817 to aslink (it is not longer 0x30 by default). If --stack-loc passes
4818 the begining of the stack area to aslink.
4820 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
4821 glue() in SDCCglue.c creates an area for it.
4823 2002-09-03 Borut Razem <borut.razem AT siol.net>
4824 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,

4826 introduced atexit() handler for teporay files removal in case of
4827 errors, assertions, ...
4829 2002-08-29 Borut Razem <borut.razem AT siol.net>
4830 * sdcc/support/cpp2/auto-host_vc_in.h:
4831 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
4832 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
4833 Maybe there is a similar problem with BORLANDC? It should be checked!
4835 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
4836 corrected improper use of assert: the assignment to clr variable was done inside the assert.
4837 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
4838 was not executed, and the compiler (cl) launched a warning:
4839 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
4841 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
4842 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
4844 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
4845 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
4847 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
4848 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
4849 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
4850 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
4851 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
4852 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
4853 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
4854 - added Release configuration in VS projects
4855 - review of compiler an linker options
4856 - VC .exe files are generated in bin_vc directory, not to interfere
4857 with binaries generated from other projects (cygwin, mingw, bcc ...)
4859 * sdcc/src/yacc.dsp: added
4861 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
4862 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
4863 and insert the version number definitions from .version
4865 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
4867 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
4868 added - genarate auto-host.h using auto-host_vc_in.h as template
4871 removed from CVS, generated automatically
4873 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
4874 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
4876 2002-08-11 Borut Razem <borut.razem AT siol.net>
4877 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
4879 2002-08-10 Borut Razem <borut.razem AT siol.net>
4880 * src/SDCCmain.c (main):
4881 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
4882 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
4883 The consequence was that some temporary files were not removed.
4886 unification of code in functions tempfilename() and tempfile():
4887 function tempnam() is defined in Visual Studio 6.0 and .NET
4889 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
4891 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
4892 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
4893 - removed compiler command line option /WX: Treats all warnings as errors
4894 - update a list of source files, included into the project
4896 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
4897 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
4898 changed project type to Generic Project so that can be correcly converted to VS.NET project
4900 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
4902 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
4904 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
4906 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
4907 added return 0 statements after assert() to make compiler happy
4909 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
4910 added newline in the def file to keep MSC compiler satisfied
4912 * sdcc/src/z80/gen.c:
4913 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
4914 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
4915 - solved MSC error in function aopDump()
4917 * sdcc_vc.h: define PREFIX as "\\sdcc"
4919 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
4920 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

4968 Added -p option. Allows port dependent processor to be specified.
4971 Initialized the new field char *Processor field to NULL in all ports
4974 Compiler generated registers for interrupt context saving
4975 were not getting allocated.
4977 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
4980 Fixed left shift. Will promote the left side of a left shift
4981 if a) left shifting more than size of operand or b) when assigned
4982 to something size > size of left side
4984 2002-03-14 Scott Dattalo <scott AT dattalo.com>
4986 tons of changes. Register allocation has been
4987 rewritten. Added customization for the various PICs. Flow

5092 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
5094 * sdcc/src/SDCCloop.c:
5095 Previous fix was not good. basic blocks that have "break" or "return" are
5096 not really partof a loop , but live ranges used in these blocks should
5097 be live thru the entire loop, so set partOfLoop but don't add them to
5100 2002-02-21 <johan AT FRIJA>
5102 * src/SDCCcse.c: fixed bug #514308
5104 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

5110 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
5112 2002-02-10 Karl Bongers <karl AT turbobit.com>
5115 Fixed up SDCDB debugger somewhat. Updated debugger/README
5116 with lots of comments and notes.
5118 * device/examples/test2.c:

5129 Karl and Johan start ucsim XA support. Most dissassembly working,
5130 about 75% emulation done(plenty of work remaining).
5132 * sim/ucsim/z80.src:
5133 Add Z80 support to ucsim, add test-ucz80 regression test,
5134 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
