1401 loaded with the linker search paths (-L arguments) and the libraries
1402 to be linked with the current source (-l arguments). Changes
1403 currently will affect only the pic16 port.
1404 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
1405 include path the port specific paths and port specific libraries,
1406 * gplink command now contains the $3 argument,

1422 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
1424 Documenting changes from previous commits.
1425 * configure.in (version 1.56),
1426 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
1427 when generating output files to configure the pic16 library,
1428 but now I've commented it out, since gputils aren't installed in the
1429 SF compile farm, so library won't compile
1431 * device/lib/Makefile.in (version 1.56): initially I've added in
1432 target 'all' the prerequestive 'model-pic16' so it compiled the
1433 pic16 library, but now I've commented it out for the same reasons
1435 * added targets 'model-pic16' and 'objects-pic16' to compile the
1437 * added target 'port-specific-objects-pic16' to handle the
1438 generated libraries and copy them into the build/ directory
1439 * added target 'clean-intermediate-pic16' to clean intermediate
1440 files into pic16 directory
1441 * in target 'installdirs' added line to create directory pic16 in
1442 the installation path
1444 * device/include/Makefile.in (version 1.11): in target 'install'
1445 added lines to copy all header files to installation path,
1446 * in target 'installdirs' added line create directory for pic16
1447 headers in the installation path
1449 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

1462 * src/z80/main.c (_parseOptions): fixed the portmode= command line
1463 option so that it actually works. Made it specific to the z80, since
1464 the gbz80 doesn't have these kinds of I/O ports.
1466 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1468 * device/include/z180.h,

1474 * device/lib/_strcmp.c,
1475 * device/lib/_strtok.c: fixed pragmas to non-deprecated form
1476 * src/z80/main.c (_process_pragma): add support for pragmas bank and
1477 portmode; added deprecation warning for bank= and protmode= forms.
1478 Also, guard against buffer overflow.
1479 * src/z80/gen.c (aopGet): generate better code for sfr banked read
1481 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1483 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
1484 changed interrupt vector table generation to only emit declared vectors.
1485 * device/include/Makefile.in: added missing backslash
1486 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
1488 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
1490 Mainly changes to support compilation of the device libraries
1491 * src/pic16/device.c: stack is allocated via symbol and not
1492 via literal number. The symbol is placed in the corresponding
1493 position of the data ram
1494 * (pic16_dump_section): relocatable and absolute uninitialized
1495 data are now emitted in sorted order to reduce section naming,
1496 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
1497 weren't marked as being in the access bank,
1499 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
1501 Added portion of GNU PIC Library under the directory
1502 device/include/pic16 and device/lib/pic16. These files
1503 contain the declarations of SFRs for the PIC18Fxx2 devices.
1504 The directory is initialized via configure from toplevel.
1506 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
1508 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
1509 the spilllocations to be compared correctly

1533 * doc/sdccman.lyx: Moved and added some sections, small changes
1534 all over. Telling LaTeX to be less strict with word spacing
1535 to better keep the right margin. Changed some notes about
1536 maintainance of the ports in section 3.2.1 - is it OK like this?
1538 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

1575 UPPER for immediate operands,
1576 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
1578 * src/pic16/peeph.def: all peepholes with movff are commented out,
1579 because there is a problem in the pcode peep optimizer,
1580 * src/pic16/ralloc.c: the register allocator can now reuse local

1582 * src/pic16/ralloc.h: added flag isLocal in structure regs,
1584 Added file src/pic16/NOTES with information about program writing on
1585 the current port version.

1617 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1620 * src/z80/main.c: added missed needLinkerScript flags (more than
1621 one port structure defined in these file)
1622 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

1644 * (pic14emitOverlay): modified to emit a commented overlay segment
1645 directive when no overlay data exist
1646 * (picglue): modified to emit uninitialized data segment
1647 according to udata_section_name

1657 2004-01-07 Borut Razem <borut.razem AT siol.net>
1659 * support/scripts/sdcc.nsi: update PATH
1660 * support/scripts/sdcc.ico: craeted

1673 include information about variables allocated to the overlay
1676 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
1678 * as/mcs51/lkmain.c: Help about -Y option

1690 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
1692 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
1693 (default behaviour).
1695 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1697 A python script to validate compiler diagnostic messages. It can be
1698 used to verify that sdcc complains about bad c source code and
1699 gives a good location of the error.
1700 * support/valdiag/Makefile,
1701 * support/valdiag/valdiag.py,
1702 * support/valdiag/tests/*
1704 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

1717 * src/common.h: added ifndef/define/endif macros
1718 around the header file.
1719 Bug reported from Jesus Calvino-Fraga
1721 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
1723 * sdcc.spec: updated
1724 * device/include/Makefile.in: don't install CVS directories
1725 * device/lib/Makefile.in: added removal of CVS directories after install
1726 * doc/Makefile: fixed install, added local_icons
1727 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
1728 * src/mcs51/gen.c (genRightShift): fixed bug #870788
1729 * src/ds390/gen.c (genRightShift): fixed bug #870788
1730 * src/SDCCast.c (decorateType): fixed bug #870781
1732 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
1734 PIC16 port related changes:
1735 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
1736 added variable stackPos,
1738 * gen.c: genCall, assignResultValue: added support for
1739 pushing/retrieving function parameters to/from stack,
1740 genFunction,genEndFunction: setup stack frame for the
1742 genAddrOf: will be changed according to bug 863624
1744 * added files genutils.c and genutils.h which contain gen*
1745 debugged and optimised functions extracted from gen.c
1747 * glue.c: added variable 'externs' which holds extern symbols,
1748 pic16emitRegularMap: is modified to properly handle relocatable
1749 symbols under the new scheme,
1750 pic16createInterruptVect: is modified
1751 pic16printPublics: is modified to emit 'global' assembler directives,
1752 added pic16_printExterns to print extern symbols,
1753 pic16glue: initializes stack/frame pointer in the beginning of
1754 the assembly output. Temporary hack, will be corrected later,
1755 because gplink yet does not support stack and SDCC does not
1756 yet support a type of crt0.o object to create the final binary.
1758 * Removed many lines that contain 8051 legacy code.
1759 * The code is finally placed under a 'code' directive.
1760 * Added port specific options.
1762 * _process_pragma: simplified since now we do not need *special*
1763 include file to define SFR registers. But a separate header
1764 will be needed. This will be developed later.
1765 * _pic16_parseOptions: added, parses port specific options:
1766 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
1767 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
1768 --preplace-udata-with=
1770 * _pic16_setDefaultOptions: modified to initialize section names,
1771 but hack is temporarly out of order since it needs improvement.
1772 * _pic16_genAssemblerPreamble: configuration words are emitted by
1773 their address instead of their name. This part is incomplete and
1774 supports only the 18Fxx2 devices. Other devices will emit an error
1775 during assembly since they do not contain the same set of config
1777 * _pic16_genIVT: is modified,
1779 * pcode.c: added definitions for some hardware registers that are needed
1781 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
1782 All PCI entries are updated. Now LFSR is supported.
1783 * Removed pic16_pciTRIS is mentioned by mdubuc in source
1784 * added pic16_newpCodeOpLit2 to support instructions with
1785 two literal arguments
1786 * pic16_pCode2str: corrected code that emits assembler instructions
1787 with two literal operands and those that have an access bit modifier
1788 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
1789 this fixes a bug which caused some labels to be lost, when an
1790 assembler directive was added, i.e. banksel,
1791 * pic16_FixRegisterBanking: improved logic that causes the insertion
1793 * InlineFunction: functions that are called once, are not any more
1794 inlined. This can be a port option in the future,
1796 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
1798 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
1799 hold the corresponding uninitialized symbols,
1800 * pic16_allocProcessorRegister: registers have explicit marked the
1802 * pic16_allocInternalRegister: registers are explicit marked as
1804 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
1805 processing list, so bit registers were lost,
1808 * ralloc.h: added field 'accessBank' and original symbol operand
1809 in register definition,
1810 * removed the field isMapped from register definition,
1812 ** Several functions have been removed from various sources:
1813 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
1814 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
1815 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
1816 pic16_assignRelocatableRegisters
1818 ** others have been introduced:
1819 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
1820 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
1822 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
1824 * support/scripts/inc2h.pl: changed definition of BIT_AT
1825 to emit 'sbit at' instead of 'bit at'. This was a request.
1827 PIC16 port related preliminary changes:
1828 * gen.c: prefixed function popRegFromString with
1829 pic16_ and all references to it corrected
1830 * pcode.c: all pic16_pc_* hardware registers prefixed
1831 with underscore (_),
1832 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
1833 * ralloc.c: newReg(): when register is REG_SFR then
1834 set address to rIdx,
1835 pic16_allocProcessorRegister(): marks register wasUsed=0
1836 pic16_writeUsedRegs(): added a call to assign processor
1837 registers via pic16_assignFixedRegisters
1839 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
1841 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
1842 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
1843 variables in unused register banks. Also the SSEG is placed
1844 wherever there is enough space for it, and IDATA can be anywhere
1845 in internal RAM. For now compile using -Wl-Y[stack_size].
1846 The mem file is different for this option as well, since it
1847 makes no sense of talking about DSEG lenght.
1849 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
1851 * src/SDCClrange.c: fixed bug 869095 that caused segfault
1852 in certain cases, e.g. when ROM assignment, patch provided
1853 from Albert den Haan.
1855 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

2402 Fixed a number of problems revealed by bug #827883.
2403 * src/SDCCloop.c (loopInvariants): Spill location of the
2404 result operand should be recomputed if extracted from
2405 a loop. Also, don't extract assignments of an iTemp
2407 * src/SDCCast.c (isConformingBody): loop reversal should
2408 not occur if the control variable is involved with a
2409 relational operator.

2905 an association between the assembly source code and the
2906 iCodes that originated them. Put this information to use
2907 with a new peephole rule condition "notVolatile" so that
2908 the rules can be aggressive yet still safe.
2913 * src/mcs51/peeph.def
2915 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2919 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
2920 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
2921 if the left or right operand symbols have the accuse flag set.
2923 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2925 Changed the type of the result of the ! (NOT) operator to char;
2926 previously it returned the same type as the source. This allows
2927 us to eliminate all the genFloatNot functions (all of its target
2928 implementations were very buggy) since !float can use the same
2931 * src/SDCCicode.c (ast2iCode): ! returns char
2932 * src/mcs51/gen.c (genNot, genNotFloat),
2933 * src/ds390/gen.c (genNot, genNotFloat),
2934 * src/z80/gen.c (genNot, genNotFloat),

2940 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
2941 1. Interrupt would not compile properly. Ensure PCLATH register is saved
2942 during interrupts. Ensure WSAVE is located at a shared bank address.
2943 2. Fixed page selection in some places
2944 3. Fixed BTFSS/C to where necessary use registers directly and not simply
2945 the registers name strings.
2946 4. Fixed "signed / unsigned compare" compiler warnings.
2947 5. The PIC port manages its own allocation of the general purpose
2948 registers, but makes no attempt to reuse them. As a result when
2949 compiling it soon runs out of general purpose registers. Some
2950 additional code was added to the files pcode.c and device.c to walk
2951 through the function call tree and rename the registers so that they
2961 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
2962 genPlus() & genMinus() when the result is the same as left or right

2968 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2970 Made bitfield a distinct type from bit so that bitfields
2971 convert as per ANSI C and bits retain their traditional
2972 boolean style behaviour. Implemented bitfield support in
2980 * src/ds390/gen.c: bit v bitfield split
2981 * src/z80/gen.c: New support for bitfields
2982 * support/regression/tests/bitfields.c: reenabled z80,
2985 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
2987 Rules 246.x, 247.x relate to bitfields, the others speed up
2988 access to xdata mapped I/O devices.
2990 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
2992 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2994 Cleaned up genPackBits and genUnpackBits and added two helper
2995 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
2996 for literal assignments in genPackBits (thanks to Frieder for
3002 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3004 Fixed bug #748310 (pointer to function type mishandled when the
3005 function name is omitted). Also fixed a SIGSEGV when a function
3006 attribute (reentrant, etc) is used on a non-function or on a
3007 function but misplaced before the parameter list.

3034 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3036 Made the constant following the "interrupt" keyword optional. If
3037 omitted, the function will not automatically be given an entry
3038 in the interrupt vector table (similar to #pragma NOIV, but
3039 less syntacticly kludgy). The interrupt number is also now
3040 range checked. Also fixed a bug in the high order bit example

3061 unsigned, but are signed by default
3062 * src/SDCCval.c (constVal): rearranged
3063 * src/SDCCval.c (valMod): preliminary fix
3064 * src/SDCCval.c (valCastLiteral): use TYPE_* types

3501 * device/lib/gbz80/stubs.s
3502 * device/lib/z80/mul.s
3503 * device/lib/z80/stubs.s
3504 * src/SDCCsymt.c (initCSupport)
3506 2003-05-25 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3508 * as/mcs51/lkaomf51.c: Address space 'z' was missing.
3509 * src/avr/avr.dsp, src/ds390/ds390.dsp, src/mcs51/mcs51.dsp,
3510 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
3511 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used
3514 2003-05-25 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3516 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
3517 the regression tests I'm not brave enough to enable 245.b, 245.c
3518 * doc/sdccman.lyx: added latex preamble for hyperref package.
3519 Using pdflatex this will give you a hyperlinked pdf file with
3520 bookmarks. (prepend '%' before /usepackage if this breaks something)
3522 2003-05-24 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

3534 2003-05-19 Bernhard Held <bernhard AT bernhardheld.de>
3536 Applied patch from bug 737905 (renamed yylineo to mylineno):
3543 * src/pic16/pcode.c: Cleaned warnings
3544 * src/pic16/pcodeflow.c: Cleaned warnings
3545 * src/pic16/pcoderegs.c: Cleaned warnings

3558 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
3560 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
3561 it can be defined with CFLAGS when running configure
3562 * src/SDCCmain.c: fixed compiling + linking with object files
3564 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
3566 * configure.in: configure for pic16 port,
3567 added --disable-pic16-port
3568 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
3569 * src/SDCCmain.c: linkOptions is changed to set *,
3570 added if/endif conditional macros to remove options help
3571 messages from optionsTable when a port is not configured, added
3572 support for the PIc16 port in the ports table, when executing
3573 the compiler with no port specified on command line, a default
3574 port is selected with the new macro DEFAULT_PORT which is
3575 defined in port.h, in setDefaultOptions() linkOptions is removed
3576 from initialization assignment, since now it is a set,
3577 parseCmdLine uses setParseWithComma for linkOptions, in
3578 linkEdit() linkOptions are accessed with new function indexSet()
3579 which returns the i'th item of a set variable. See SDCCset.c, in
3580 linkEdit() when calling buildCmdLine(), added linkOptions as
3581 last argument. Now users can pass arguments to gplink via the
3582 -Wl option, main() uses pic16glue() to glue up pic16 programs
3583 * src/SDCCpeeph.c: various changes to support pic16
3584 * src/SDCCset.c: added function void *indexSet(set *, int) to

3592 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
3594 * src/pic16/glue.c: commented out some error producing lines
3595 * src/pic16/main.c: __config directives are commented out to stop
3596 gpasm complaining and test the linkage with gplink, _linkCmd and
3597 _asmCmd changed to be more gplink and gpasm friendly
3598 * src/pic16/peeph.def: peep rule 3 is commented out, since it
3599 produced an error when parsed, peep rule 12 is added to utilize
3600 movff, but it is commented out since the pCode does not support
3601 yet a command with 2 address arguments
3603 2003-05-18 <johan AT balder>
3605 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
3606 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT
3607 2003-05-17 Karl Bongers(apply patches from Martin Helmling)

3625 on entry now. Add tbreak. Other enhancements and fixes for use
3628 2003-05-12 Borut Razem <borut.razem AT siol.net>
3630 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
3632 2003-05-11 Borut Razem <borut.razem AT siol.net>
3634 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
3635 the path of bin directory, so that PATH is the only env. variable, which has to be set
3636 in case of standard installation.
3637 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

4640 * src/SDCCicode.c: fixed array add
4642 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
4643 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
4644 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
4646 2003-01-04 <johan AT balder>
4648 * src/SDCCval.c (getNelements): fixed the initialized array of structures
4650 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4651 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
4653 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

4660 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
4661 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
4663 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
4664 * src/mcs51/main.c: removed {bindir}{sep} from aslink
4666 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4668 * in \sdcc\as\mcs51\ changed these files in order to create an
4669 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
4670 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
4671 following files to include the previous two files: aslink.dsp,
4672 Makefile.aslink, Makefile.bcc, and Makefile.in.
4674 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
4675 .adb instead of .cdb
4677 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4679 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
4680 value from option --iram-size.
4682 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4684 * \sdcc\as\mcs51\lklist.c: added boundary check before using
4687 2002-09-18 <wiml AT hhhh.org>
4689 * SDCClrange.h: exposed setFromRange() and setToRange()
4690 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
4691 packRegsForAccUse() (bug 542397)
4692 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
4693 multiple times and emitting the fetch operations more than once
4694 added aopGetUsesAcc() function to allow binary operators to
4695 fetch their operands in the correct order; made genMinus() emit
4696 compact code for X = LITERAL - Y
4698 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4699 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
4700 sprintf() in line 1267.
4702 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4703 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
4706 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4707 Changes to aslink (All the changes are marked with 'JCF'):
4709 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
4712 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
4713 area BSEG. Also moves, if possible, the DATA area down into the internal
4714 ram so more space is available.
4716 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
4719 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
4720 not bytes. Function summary() which creates a memory usage summary
4721 file with extension .mem. Reports of overlaping stack and small stack
4722 size. If the space for the stack is less than 16 bytes aslink trows a
4725 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
4726 the 8051. Option 'y' for memory summary output file.
4728 Changes to sdcc (All the changes are marked with 'JCF'):
4730 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
4732 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
4733 overlaying area for it (uses RegBankUsed[4]).
4735 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
4736 bank zero as used by default. By default aslink locates the stack
4737 (equivalent to --stack-after-data). Pass option 'y' to aslink for
4738 the creation of the .mem file. Delegates the allocation of data area
4739 to aslink (it is not longer 0x30 by default). If --stack-loc passes
4740 the begining of the stack area to aslink.
4742 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
4743 glue() in SDCCglue.c creates an area for it.
4745 2002-09-03 Borut Razem <borut.razem AT siol.net>
4746 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
4747 sdcc/src/pic/glue.c:
4748 introduced atexit() handler for teporay files removal in case of
4749 errors, assertions, ...
4751 2002-08-29 Borut Razem <borut.razem AT siol.net>
4752 * sdcc/support/cpp2/auto-host_vc_in.h:
4753 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
4754 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
4755 Maybe there is a similar problem with BORLANDC? It should be checked!
4757 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
4758 corrected improper use of assert: the assignment to clr variable was done inside the assert.
4759 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
4760 was not executed, and the compiler (cl) launched a warning:
4761 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
4763 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
4764 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
4766 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
4767 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
4769 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
4770 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,

4772 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
4773 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
4774 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
4775 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
4776 - added Release configuration in VS projects
4777 - review of compiler an linker options
4778 - VC .exe files are generated in bin_vc directory, not to interfere
4779 with binaries generated from other projects (cygwin, mingw, bcc ...)
4781 * sdcc/src/yacc.dsp: added
4783 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
4784 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
4785 and insert the version number definitions from .version
4787 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
4789 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
4790 added - genarate auto-host.h using auto-host_vc_in.h as template
4793 removed from CVS, generated automatically
4795 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
4796 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
4798 2002-08-11 Borut Razem <borut.razem AT siol.net>
4799 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
4801 2002-08-10 Borut Razem <borut.razem AT siol.net>
4802 * src/SDCCmain.c (main):
4803 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
4804 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
4805 The consequence was that some temporary files were not removed.
4808 unification of code in functions tempfilename() and tempfile():
4809 function tempnam() is defined in Visual Studio 6.0 and .NET
4811 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a

5016 * sdcc/src/SDCCloop.c:
5017 Previous fix was not good. basic blocks that have "break" or "return" are
5018 not really partof a loop , but live ranges used in these blocks should
