1709 * doc/sdccman.lyx: some reorganization of the PIC16 part, added many
1710 information on the new functions of the c library and more...
1712 2005-03-28 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1714 * src/SDCCBBlock.c (iCodeBreakDown): fixed bug #1170212
1716 2005-03-26 Raphael Neider <rneider AT web.de>
1718 * src/pic16/gen.c (genSkipc): fixed semantics (execute branch
1719 if condition == CARRY)
1720 * (genCmp): adapted to new genSkipc semantics
1721 * src/pic16/genutils.c (pic6_genCmp_special): removed side effect
1722 on rIfx (genCmp was broken)
1724 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1726 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
1727 * src/z80/main.c (_keywords[]),
1728 * src/SDCCglobal.h (struct options),
1730 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
1731 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
1732 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1733 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1734 always available in leading double underscore form. The C99 support is
1735 mostly missing, but it's a start.
1736 * support/regression/tests/bug-227710.c: fixed nonconforming use of
1737 reserved identifier "__data".
1739 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

1783 immedDom() returning wrong block; probably fixes bug #1160833)
1785 2005-03-20 Borut Razem <borut.razem AT siol.net>
1787 * support/scripts/inc2h.pl: WIN32 port

1793 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
1795 * device/include/stdint.h: added
1796 * device/lib/abs.c: added
1797 * device/lib/labs.c: added
1798 * device/include/stdlib.h: added abs() and labs() prototypes

1813 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
1815 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1817 * device/lib/printf_large.c: removed inline assembly for portability and
1818 readability. Use printf_fast if speed or size are more important.
1819 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1820 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1822 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1824 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1825 prevent compiler warning
1827 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1829 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1830 moved to level 0 and declared as static. Also they are explicit
1831 placed in access bank. This was necessery because some times they
1832 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1833 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1834 optimizations. Currently only compare to unsigned char is implemented,
1835 * src/pic16/gen.c: added fReturnIdx array,
1836 * (struct resolvedIfx) is moved to gen.h and made public,
1837 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1838 * (aopForSym): added an optimization to directly store in stack of
1839 the operand of a SEND iCode,
1840 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1841 but as registers instead (AOP_REG) using the fReturnIdx array,
1842 * (pic16_freeAsmop): remove the freed register from the
1843 _G.sregsAlloc field,
1844 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1845 a compare of 'WREG',
1846 * (pic16_popGetTempRegCond): changed function prototype, now
1847 function takes also a bitVector argument v which holds the current
1848 set of registers that are allocated for stack access by aopForSym,
1849 registers allocated in aopForSym for accessing stack symbols are not
1850 any more part of the functions usedRegs field,
1851 * (genCall): some times aopOp is called for a stack variable to be
1852 send, aopForSym might perform the push, if this is true make sure
1853 that genCall doesn't push the variable twice by testing _G.resDirect,
1854 * (genFunction): changed testing for unspecified interrupt number
1855 from 256 to INTNO_UNSPEC,
1856 * modified selection scheme of frame pointer generation. Previously
1857 if function did use local registers a frame pointer was generated,
1858 now a frame pointer is generated only if function has arguments
1859 (that need PLUSW2 register access), or has stack arguments, or the
1860 compiler is not instructed to omit the frame pointer,
1861 * (genEndFunction): before restoring local registers that were saved
1862 in the function preamble, also restore the registers that *might*
1863 have been allocated for stack access,
1864 * (genRet): removed some old comments,
1865 * (genCmp, the active (RN's) version): added a call to the
1866 pic16_genCmp_special function to perform the compare with a more
1867 robust and optimized way,
1868 * (genInline): a feature has been added in inline code generation,
1869 which allows a wildcard variable substitution when writing inline
1870 assembly. Code is incomplete and experimental therefore undocumented,
1871 * (genCast): changed order of aopOp for result and right to allow
1872 aopForSym to directly load the result if possible,
1873 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1874 perform an optimized compare on some selected special occasions,
1875 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1876 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1877 generate an IVT any more,
1878 * src/pic16/main.c (pic16_optionsTable): added command line option
1880 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1881 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1883 * src/pic16/NOTES: Raphael Neider added in list of active developers
1884 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1885 jumptable_end to prevent bug #,
1886 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1887 inCond and outCond fields,
1888 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1889 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1890 turn off register spilling,
1891 * (packRegsForOneUse): synced with other ports' versions although it
1892 is not used currently,
1893 * (pic16_packRegisters): added an optimization while reading
1894 structure bitfields, some registers may be saved (malloc code is
1895 decreased by 80 bytes)
1897 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1899 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1900 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1901 this can be optimized more?
1903 2005-03-10 Raphael Neider <rneider AT web.de>
1905 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1906 genNearPointerGet): (hopefully) fixed access to bitfields via
1907 pointers (p->bitN = x; and x = p->bitN; failed)
1909 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

2096 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
2097 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
2098 this might fix SIGSEGVs on MinGW...
2099 * src/SDCCopt.c (killDeadCode): restored original behaviour
2100 (volatile operands might get thrown away though)
2102 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

2542 generated for switch statements. For now you need to set the
2543 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2544 Now 4 algorithms for mcs51 jumptable generation are used:
2545 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2546 addresses loaded pc-relative for up to 112 cases and stack-pushing
2547 target addresses loaded with offset from dptr for up to 256 cases.

5625 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5627 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5628 loaded with the linker search paths (-L arguments) and the libraries
5629 to be linked with the current source (-l arguments). Changes
5630 currently will affect only the pic16 port.
5631 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5632 include path the port specific paths and port specific libraries,
5633 * gplink command now contains the $3 argument,
5634 * src/pic16/device.h,
5635 * src/pic16/device.c,: structure PIC_device is made public and
5636 renamed to PIC16_device, the same for variable Pics which is renamed

5651 Documenting changes from previous commits.
5652 * configure.in (version 1.56),
5653 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5654 when generating output files to configure the pic16 library,
5655 but now I've commented it out, since gputils aren't installed in the
5656 SF compile farm, so library won't compile
5658 * device/lib/Makefile.in (version 1.56): initially I've added in
5659 target 'all' the prerequestive 'model-pic16' so it compiled the
5660 pic16 library, but now I've commented it out for the same reasons
5662 * added targets 'model-pic16' and 'objects-pic16' to compile the
5664 * added target 'port-specific-objects-pic16' to handle the
5665 generated libraries and copy them into the build/ directory
5666 * added target 'clean-intermediate-pic16' to clean intermediate
5667 files into pic16 directory
5668 * in target 'installdirs' added line to create directory pic16 in
5669 the installation path
5671 * device/include/Makefile.in (version 1.11): in target 'install'
5672 added lines to copy all header files to installation path,
5673 * in target 'installdirs' added line create directory for pic16
5674 headers in the installation path

5687 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5689 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5690 option so that it actually works. Made it specific to the z80, since
5691 the gbz80 doesn't have these kinds of I/O ports.
5693 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5695 * device/include/z180.h,

5761 all over. Telling LaTeX to be less strict with word spacing
5762 to better keep the right margin. Changed some notes about
5763 maintainance of the ports in section 3.2.1 - is it OK like this?
5765 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5900 include information about variables allocated to the overlay
5903 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5905 * as/mcs51/lkmain.c: Help about -Y option

5917 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5919 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5920 (default behaviour).
5922 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5924 A python script to validate compiler diagnostic messages. It can be
5925 used to verify that sdcc complains about bad c source code and
5926 gives a good location of the error.
5927 * support/valdiag/Makefile,
5928 * support/valdiag/valdiag.py,
5929 * support/valdiag/tests/*
5931 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5946 Bug reported from Jesus Calvino-Fraga
5948 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5950 * sdcc.spec: updated
5951 * device/include/Makefile.in: don't install CVS directories
5952 * device/lib/Makefile.in: added removal of CVS directories after install
5953 * doc/Makefile: fixed install, added local_icons
5954 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5955 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5956 * src/ds390/gen.c (genRightShift): fixed bug #870788
5957 * src/SDCCast.c (decorateType): fixed bug #870781
5959 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5961 PIC16 port related changes:
5962 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5963 added variable stackPos,
5965 * gen.c: genCall, assignResultValue: added support for
5966 pushing/retrieving function parameters to/from stack,
5967 genFunction,genEndFunction: setup stack frame for the
5969 genAddrOf: will be changed according to bug 863624
5971 * added files genutils.c and genutils.h which contain gen*
5972 debugged and optimised functions extracted from gen.c
5974 * glue.c: added variable 'externs' which holds extern symbols,
5975 pic16emitRegularMap: is modified to properly handle relocatable
5976 symbols under the new scheme,
5977 pic16createInterruptVect: is modified
5978 pic16printPublics: is modified to emit 'global' assembler directives,
5979 added pic16_printExterns to print extern symbols,
5980 pic16glue: initializes stack/frame pointer in the beginning of
5981 the assembly output. Temporary hack, will be corrected later,
5982 because gplink yet does not support stack and SDCC does not
5983 yet support a type of crt0.o object to create the final binary.
5985 * Removed many lines that contain 8051 legacy code.
5986 * The code is finally placed under a 'code' directive.
5987 * Added port specific options.
5989 * _process_pragma: simplified since now we do not need *special*
5990 include file to define SFR registers. But a separate header
5991 will be needed. This will be developed later.
5992 * _pic16_parseOptions: added, parses port specific options:
5993 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5994 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5995 --preplace-udata-with=
5997 * _pic16_setDefaultOptions: modified to initialize section names,
5998 but hack is temporarly out of order since it needs improvement.
5999 * _pic16_genAssemblerPreamble: configuration words are emitted by
6000 their address instead of their name. This part is incomplete and
6001 supports only the 18Fxx2 devices. Other devices will emit an error
6002 during assembly since they do not contain the same set of config
6004 * _pic16_genIVT: is modified,
6006 * pcode.c: added definitions for some hardware registers that are needed
6008 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6009 All PCI entries are updated. Now LFSR is supported.
6010 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6011 * added pic16_newpCodeOpLit2 to support instructions with
6012 two literal arguments
6013 * pic16_pCode2str: corrected code that emits assembler instructions
6014 with two literal operands and those that have an access bit modifier
6015 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6016 this fixes a bug which caused some labels to be lost, when an
6017 assembler directive was added, i.e. banksel,
6018 * pic16_FixRegisterBanking: improved logic that causes the insertion
6020 * InlineFunction: functions that are called once, are not any more
6021 inlined. This can be a port option in the future,
6023 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6025 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6026 hold the corresponding uninitialized symbols,
6027 * pic16_allocProcessorRegister: registers have explicit marked the
6029 * pic16_allocInternalRegister: registers are explicit marked as
6031 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6032 processing list, so bit registers were lost,
6035 * ralloc.h: added field 'accessBank' and original symbol operand
6036 in register definition,
6037 * removed the field isMapped from register definition,
6039 ** Several functions have been removed from various sources:
6040 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6041 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6042 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6043 pic16_assignRelocatableRegisters
6045 ** others have been introduced:
6046 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6047 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6049 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6051 * support/scripts/inc2h.pl: changed definition of BIT_AT
6052 to emit 'sbit at' instead of 'bit at'. This was a request.
6054 PIC16 port related preliminary changes:
6055 * gen.c: prefixed function popRegFromString with
6056 pic16_ and all references to it corrected
6057 * pcode.c: all pic16_pc_* hardware registers prefixed
6058 with underscore (_),
6059 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6060 * ralloc.c: newReg(): when register is REG_SFR then
6061 set address to rIdx,
6062 pic16_allocProcessorRegister(): marks register wasUsed=0
6063 pic16_writeUsedRegs(): added a call to assign processor
6064 registers via pic16_assignFixedRegisters
6066 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6068 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6069 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6070 variables in unused register banks. Also the SSEG is placed
6071 wherever there is enough space for it, and IDATA can be anywhere
6072 in internal RAM. For now compile using -Wl-Y[stack_size].
6073 The mem file is different for this option as well, since it
6074 makes no sense of talking about DSEG lenght.
6076 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6078 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6079 in certain cases, e.g. when ROM assignment, patch provided
6080 from Albert den Haan.
6082 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7125 A few small changes that speed up the peephole optimizer.
7129 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7131 Try to make the peephole optimizer smarter by maintaining
7132 an association between the assembly source code and the
7133 iCodes that originated them. Put this information to use
7134 with a new peephole rule condition "notVolatile" so that
7135 the rules can be aggressive yet still safe.
7140 * src/mcs51/peeph.def
7142 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7146 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),

7148 if the left or right operand symbols have the accuse flag set.
7150 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7152 Changed the type of the result of the ! (NOT) operator to char;
7153 previously it returned the same type as the source. This allows
7154 us to eliminate all the genFloatNot functions (all of its target
7155 implementations were very buggy) since !float can use the same

7167 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7168 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7169 during interrupts. Ensure WSAVE is located at a shared bank address.
7170 2. Fixed page selection in some places
7171 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7172 the registers name strings.
7173 4. Fixed "signed / unsigned compare" compiler warnings.
7174 5. The PIC port manages its own allocation of the general purpose
7175 registers, but makes no attempt to reuse them. As a result when
7176 compiling it soon runs out of general purpose registers. Some
7177 additional code was added to the files pcode.c and device.c to walk
7178 through the function call tree and rename the registers so that they

7195 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7197 Made bitfield a distinct type from bit so that bitfields
7198 convert as per ANSI C and bits retain their traditional
7199 boolean style behaviour. Implemented bitfield support in
7207 * src/ds390/gen.c: bit v bitfield split
7208 * src/z80/gen.c: New support for bitfields
7209 * support/regression/tests/bitfields.c: reenabled z80,
7212 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

7215 access to xdata mapped I/O devices.
7217 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7219 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7221 Cleaned up genPackBits and genUnpackBits and added two helper
7222 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7223 for literal assignments in genPackBits (thanks to Frieder for
7229 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7231 Fixed bug #748310 (pointer to function type mishandled when the
7232 function name is omitted). Also fixed a SIGSEGV when a function
7233 attribute (reentrant, etc) is used on a non-function or on a
7234 function but misplaced before the parameter list.
7236 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7238 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

7261 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7263 Made the constant following the "interrupt" keyword optional. If
7264 omitted, the function will not automatically be given an entry
7265 in the interrupt vector table (similar to #pragma NOIV, but
7266 less syntacticly kludgy). The interrupt number is also now
7267 range checked. Also fixed a bug in the high order bit example

7288 unsigned, but are signed by default
7289 * src/SDCCval.c (constVal): rearranged
7290 * src/SDCCval.c (valMod): preliminary fix
7291 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7785 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
7787 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
7788 it can be defined with CFLAGS when running configure
7789 * src/SDCCmain.c: fixed compiling + linking with object files
7791 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
7793 * configure.in: configure for pic16 port,
7794 added --disable-pic16-port
7795 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7796 * src/SDCCmain.c: linkOptions is changed to set *,
7797 added if/endif conditional macros to remove options help
7798 messages from optionsTable when a port is not configured, added
7799 support for the PIc16 port in the ports table, when executing
7800 the compiler with no port specified on command line, a default
7801 port is selected with the new macro DEFAULT_PORT which is
7802 defined in port.h, in setDefaultOptions() linkOptions is removed
7803 from initialization assignment, since now it is a set,
7804 parseCmdLine uses setParseWithComma for linkOptions, in
7805 linkEdit() linkOptions are accessed with new function indexSet()
7806 which returns the i'th item of a set variable. See SDCCset.c, in
7807 linkEdit() when calling buildCmdLine(), added linkOptions as
7808 last argument. Now users can pass arguments to gplink via the
7809 -Wl option, main() uses pic16glue() to glue up pic16 programs
7810 * src/SDCCpeeph.c: various changes to support pic16

7821 * src/pic16/glue.c: commented out some error producing lines
7822 * src/pic16/main.c: __config directives are commented out to stop
7823 gpasm complaining and test the linkage with gplink, _linkCmd and
7824 _asmCmd changed to be more gplink and gpasm friendly
7825 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7826 produced an error when parsed, peep rule 12 is added to utilize
7827 movff, but it is commented out since the pCode does not support
7828 yet a command with 2 address arguments
7830 2003-05-18 <johan AT balder>
7832 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7859 2003-05-11 Borut Razem <borut.razem AT siol.net>
7861 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7862 the path of bin directory, so that PATH is the only env. variable, which has to be set

8867 * src/SDCCicode.c: fixed array add
8869 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
8870 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
8871 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
8873 2003-01-04 <johan AT balder>
8875 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8877 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8878 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
8880 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

8890 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8891 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8893 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8895 * in \sdcc\as\mcs51\ changed these files in order to create an
8896 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8897 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8898 following files to include the previous two files: aslink.dsp,
8899 Makefile.aslink, Makefile.bcc, and Makefile.in.
8901 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8902 .adb instead of .cdb
8904 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8906 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8907 value from option --iram-size.
8909 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8911 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8914 2002-09-18 <wiml AT hhhh.org>
8916 * SDCClrange.h: exposed setFromRange() and setToRange()
8917 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8918 packRegsForAccUse() (bug 542397)
8919 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8920 multiple times and emitting the fetch operations more than once
8921 added aopGetUsesAcc() function to allow binary operators to
8922 fetch their operands in the correct order; made genMinus() emit
8923 compact code for X = LITERAL - Y
8925 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8926 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8927 sprintf() in line 1267.
8929 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8930 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8933 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8934 Changes to aslink (All the changes are marked with 'JCF'):
8936 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8939 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8940 area BSEG. Also moves, if possible, the DATA area down into the internal
8941 ram so more space is available.
8943 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8946 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8947 not bytes. Function summary() which creates a memory usage summary
8948 file with extension .mem. Reports of overlaping stack and small stack
8949 size. If the space for the stack is less than 16 bytes aslink trows a
8952 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8953 the 8051. Option 'y' for memory summary output file.
8955 Changes to sdcc (All the changes are marked with 'JCF'):
8957 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8959 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8960 overlaying area for it (uses RegBankUsed[4]).
8962 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8963 bank zero as used by default. By default aslink locates the stack
8964 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8965 the creation of the .mem file. Delegates the allocation of data area
8966 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8967 the begining of the stack area to aslink.
8969 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8970 glue() in SDCCglue.c creates an area for it.
8972 2002-09-03 Borut Razem <borut.razem AT siol.net>
8973 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8974 sdcc/src/pic/glue.c:
8975 introduced atexit() handler for teporay files removal in case of
8976 errors, assertions, ...
8978 2002-08-29 Borut Razem <borut.razem AT siol.net>
8979 * sdcc/support/cpp2/auto-host_vc_in.h:
8980 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8981 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8982 Maybe there is a similar problem with BORLANDC? It should be checked!
8984 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8985 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8986 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8987 was not executed, and the compiler (cl) launched a warning:
8988 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8990 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8991 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8993 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8994 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8996 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8997 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8998 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8999 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9000 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9001 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9002 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9003 - added Release configuration in VS projects
9004 - review of compiler an linker options
9005 - VC .exe files are generated in bin_vc directory, not to interfere
9006 with binaries generated from other projects (cygwin, mingw, bcc ...)
9008 * sdcc/src/yacc.dsp: added
9010 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9011 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9012 and insert the version number definitions from .version
9014 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9016 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9017 added - genarate auto-host.h using auto-host_vc_in.h as template
9020 removed from CVS, generated automatically
9022 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9023 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9025 2002-08-11 Borut Razem <borut.razem AT siol.net>
9026 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9028 2002-08-10 Borut Razem <borut.razem AT siol.net>
9029 * src/SDCCmain.c (main):
9030 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9031 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9032 The consequence was that some temporary files were not removed.
9035 unification of code in functions tempfilename() and tempfile():
9036 function tempnam() is defined in Visual Studio 6.0 and .NET
9038 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9040 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9041 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9042 - removed compiler command line option /WX: Treats all warnings as errors
9043 - update a list of source files, included into the project
9045 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9046 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9047 changed project type to Generic Project so that can be correcly converted to VS.NET project
9049 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9051 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9053 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9055 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9056 added return 0 statements after assert() to make compiler happy
9058 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9059 added newline in the def file to keep MSC compiler satisfied
9061 * sdcc/src/z80/gen.c:
9062 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9063 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9064 - solved MSC error in function aopDump()
9066 * sdcc_vc.h: define PREFIX as "\\sdcc"
9068 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9069 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
9071 2002-06-22 Scott Dattalo <scott AT dattalo.com>
9072 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9073 - Rewrote the register banking algorithm.
9074 - Added pCode live-range analysis to registers (for now, only non-used and
9075 singly-used registers optimized away)
9077 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
