1818 loaded with the linker search paths (-L arguments) and the libraries
1819 to be linked with the current source (-l arguments). Changes
1820 currently will affect only the pic16 port.
1821 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
1822 include path the port specific paths and port specific libraries,

1841 Documenting changes from previous commits.
1842 * configure.in (version 1.56),
1843 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
1844 when generating output files to configure the pic16 library,
1845 but now I've commented it out, since gputils aren't installed in the
1846 SF compile farm, so library won't compile
1848 * device/lib/Makefile.in (version 1.56): initially I've added in
1849 target 'all' the prerequestive 'model-pic16' so it compiled the
1850 pic16 library, but now I've commented it out for the same reasons
1852 * added targets 'model-pic16' and 'objects-pic16' to compile the
1854 * added target 'port-specific-objects-pic16' to handle the
1855 generated libraries and copy them into the build/ directory
1856 * added target 'clean-intermediate-pic16' to clean intermediate
1857 files into pic16 directory
1858 * in target 'installdirs' added line to create directory pic16 in
1859 the installation path
1861 * device/include/Makefile.in (version 1.11): in target 'install'
1862 added lines to copy all header files to installation path,
1863 * in target 'installdirs' added line create directory for pic16
1864 headers in the installation path
1866 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

1879 * src/z80/main.c (_parseOptions): fixed the portmode= command line
1880 option so that it actually works. Made it specific to the z80, since
1881 the gbz80 doesn't have these kinds of I/O ports.
1883 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1885 * device/include/z180.h,

1907 Mainly changes to support compilation of the device libraries
1908 * src/pic16/device.c: stack is allocated via symbol and not
1909 via literal number. The symbol is placed in the corresponding
1910 position of the data ram
1911 * (pic16_dump_section): relocatable and absolute uninitialized
1912 data are now emitted in sorted order to reduce section naming,
1913 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
1914 weren't marked as being in the access bank,
1916 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
1918 Added portion of GNU PIC Library under the directory
1919 device/include/pic16 and device/lib/pic16. These files
1920 contain the declarations of SFRs for the PIC18Fxx2 devices.
1921 The directory is initialized via configure from toplevel.
1923 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
1925 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
1926 the spilllocations to be compared correctly
1928 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
1930 * src/SDCCast.c (decorateType): fixed bug introduced today
1932 2004-01-12 Borut Razem <borut.razem AT siol.net>

1950 * doc/sdccman.lyx: Moved and added some sections, small changes
1951 all over. Telling LaTeX to be less strict with word spacing
1952 to better keep the right margin. Changed some notes about
1953 maintainance of the ports in section 3.2.1 - is it OK like this?
1955 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

1992 UPPER for immediate operands,
1993 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
1995 * src/pic16/peeph.def: all peepholes with movff are commented out,
1996 because there is a problem in the pcode peep optimizer,
1997 * src/pic16/ralloc.c: the register allocator can now reuse local

1999 * src/pic16/ralloc.h: added flag isLocal in structure regs,
2001 Added file src/pic16/NOTES with information about program writing on
2002 the current port version.

2034 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2037 * src/z80/main.c: added missed needLinkerScript flags (more than
2038 one port structure defined in these file)
2039 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

2074 2004-01-07 Borut Razem <borut.razem AT siol.net>
2076 * support/scripts/sdcc.nsi: update PATH
2077 * support/scripts/sdcc.ico: craeted

2090 include information about variables allocated to the overlay
2093 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2095 * as/mcs51/lkmain.c: Help about -Y option

2107 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2109 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
2110 (default behaviour).
2112 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2114 A python script to validate compiler diagnostic messages. It can be
2115 used to verify that sdcc complains about bad c source code and
2116 gives a good location of the error.
2117 * support/valdiag/Makefile,
2118 * support/valdiag/valdiag.py,
2119 * support/valdiag/tests/*

2136 Bug reported from Jesus Calvino-Fraga
2138 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
2140 * sdcc.spec: updated
2141 * device/include/Makefile.in: don't install CVS directories
2142 * device/lib/Makefile.in: added removal of CVS directories after install
2143 * doc/Makefile: fixed install, added local_icons
2144 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
2145 * src/mcs51/gen.c (genRightShift): fixed bug #870788
2146 * src/ds390/gen.c (genRightShift): fixed bug #870788
2147 * src/SDCCast.c (decorateType): fixed bug #870781
2149 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
2151 PIC16 port related changes:
2152 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
2153 added variable stackPos,
2155 * gen.c: genCall, assignResultValue: added support for
2156 pushing/retrieving function parameters to/from stack,
2157 genFunction,genEndFunction: setup stack frame for the
2159 genAddrOf: will be changed according to bug 863624
2161 * added files genutils.c and genutils.h which contain gen*
2162 debugged and optimised functions extracted from gen.c
2164 * glue.c: added variable 'externs' which holds extern symbols,
2165 pic16emitRegularMap: is modified to properly handle relocatable
2166 symbols under the new scheme,
2167 pic16createInterruptVect: is modified
2168 pic16printPublics: is modified to emit 'global' assembler directives,
2169 added pic16_printExterns to print extern symbols,
2170 pic16glue: initializes stack/frame pointer in the beginning of
2171 the assembly output. Temporary hack, will be corrected later,
2172 because gplink yet does not support stack and SDCC does not
2173 yet support a type of crt0.o object to create the final binary.
2175 * Removed many lines that contain 8051 legacy code.
2176 * The code is finally placed under a 'code' directive.
2177 * Added port specific options.
2179 * _process_pragma: simplified since now we do not need *special*
2180 include file to define SFR registers. But a separate header
2181 will be needed. This will be developed later.
2182 * _pic16_parseOptions: added, parses port specific options:
2183 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
2184 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
2185 --preplace-udata-with=
2187 * _pic16_setDefaultOptions: modified to initialize section names,
2188 but hack is temporarly out of order since it needs improvement.
2189 * _pic16_genAssemblerPreamble: configuration words are emitted by
2190 their address instead of their name. This part is incomplete and
2191 supports only the 18Fxx2 devices. Other devices will emit an error
2192 during assembly since they do not contain the same set of config
2194 * _pic16_genIVT: is modified,
2196 * pcode.c: added definitions for some hardware registers that are needed
2198 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
2199 All PCI entries are updated. Now LFSR is supported.
2200 * Removed pic16_pciTRIS is mentioned by mdubuc in source
2201 * added pic16_newpCodeOpLit2 to support instructions with
2202 two literal arguments
2203 * pic16_pCode2str: corrected code that emits assembler instructions
2204 with two literal operands and those that have an access bit modifier
2205 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
2206 this fixes a bug which caused some labels to be lost, when an
2207 assembler directive was added, i.e. banksel,
2208 * pic16_FixRegisterBanking: improved logic that causes the insertion
2210 * InlineFunction: functions that are called once, are not any more
2211 inlined. This can be a port option in the future,
2213 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
2215 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
2216 hold the corresponding uninitialized symbols,
2217 * pic16_allocProcessorRegister: registers have explicit marked the
2219 * pic16_allocInternalRegister: registers are explicit marked as
2221 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
2222 processing list, so bit registers were lost,
2225 * ralloc.h: added field 'accessBank' and original symbol operand
2226 in register definition,
2227 * removed the field isMapped from register definition,
2229 ** Several functions have been removed from various sources:
2230 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
2231 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
2232 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
2233 pic16_assignRelocatableRegisters
2235 ** others have been introduced:
2236 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
2237 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
2239 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
2241 * support/scripts/inc2h.pl: changed definition of BIT_AT
2242 to emit 'sbit at' instead of 'bit at'. This was a request.
2244 PIC16 port related preliminary changes:
2245 * gen.c: prefixed function popRegFromString with
2246 pic16_ and all references to it corrected
2247 * pcode.c: all pic16_pc_* hardware registers prefixed
2248 with underscore (_),
2249 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
2250 * ralloc.c: newReg(): when register is REG_SFR then
2251 set address to rIdx,
2252 pic16_allocProcessorRegister(): marks register wasUsed=0
2253 pic16_writeUsedRegs(): added a call to assign processor
2254 registers via pic16_assignFixedRegisters
2256 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2258 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
2259 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
2260 variables in unused register banks. Also the SSEG is placed
2261 wherever there is enough space for it, and IDATA can be anywhere
2262 in internal RAM. For now compile using -Wl-Y[stack_size].
2263 The mem file is different for this option as well, since it
2264 makes no sense of talking about DSEG lenght.
2266 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
2268 * src/SDCClrange.c: fixed bug 869095 that caused segfault
2269 in certain cases, e.g. when ROM assignment, patch provided
2270 from Albert den Haan.
2272 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

3323 iCodes that originated them. Put this information to use
3324 with a new peephole rule condition "notVolatile" so that
3325 the rules can be aggressive yet still safe.
3330 * src/mcs51/peeph.def
3332 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3336 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
3337 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
3338 if the left or right operand symbols have the accuse flag set.
3340 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3342 Changed the type of the result of the ! (NOT) operator to char;
3343 previously it returned the same type as the source. This allows
3344 us to eliminate all the genFloatNot functions (all of its target
3345 implementations were very buggy) since !float can use the same
3348 * src/SDCCicode.c (ast2iCode): ! returns char

3357 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3358 1. Interrupt would not compile properly. Ensure PCLATH register is saved
3359 during interrupts. Ensure WSAVE is located at a shared bank address.
3360 2. Fixed page selection in some places
3361 3. Fixed BTFSS/C to where necessary use registers directly and not simply
3362 the registers name strings.
3363 4. Fixed "signed / unsigned compare" compiler warnings.
3364 5. The PIC port manages its own allocation of the general purpose
3365 registers, but makes no attempt to reuse them. As a result when
3366 compiling it soon runs out of general purpose registers. Some
3367 additional code was added to the files pcode.c and device.c to walk
3368 through the function call tree and rename the registers so that they
3378 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

3385 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3387 Made bitfield a distinct type from bit so that bitfields
3388 convert as per ANSI C and bits retain their traditional
3389 boolean style behaviour. Implemented bitfield support in
3397 * src/ds390/gen.c: bit v bitfield split
3398 * src/z80/gen.c: New support for bitfields
3399 * support/regression/tests/bitfields.c: reenabled z80,
3402 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3404 Rules 246.x, 247.x relate to bitfields, the others speed up
3405 access to xdata mapped I/O devices.
3407 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
3409 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3411 Cleaned up genPackBits and genUnpackBits and added two helper
3412 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
3413 for literal assignments in genPackBits (thanks to Frieder for
3419 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3421 Fixed bug #748310 (pointer to function type mishandled when the
3422 function name is omitted). Also fixed a SIGSEGV when a function
3423 attribute (reentrant, etc) is used on a non-function or on a
3424 function but misplaced before the parameter list.

3451 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3453 Made the constant following the "interrupt" keyword optional. If
3454 omitted, the function will not automatically be given an entry
3455 in the interrupt vector table (similar to #pragma NOIV, but
3456 less syntacticly kludgy). The interrupt number is also now
3457 range checked. Also fixed a bug in the high order bit example

3914 Finalize muluint/mulsint and mululong/mulslong merging:
3915 * device/lib/_mulint.c
3916 * device/lib/_mullong.c
3917 * device/lib/gbz80/mul.s
3918 * device/lib/gbz80/stubs.s
3919 * device/lib/z80/mul.s
3920 * device/lib/z80/stubs.s
3921 * src/SDCCsymt.c (initCSupport)
3923 2003-05-25 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3925 * as/mcs51/lkaomf51.c: Address space 'z' was missing.
3926 * src/avr/avr.dsp, src/ds390/ds390.dsp, src/mcs51/mcs51.dsp,
3927 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
3928 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used
3931 2003-05-25 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3933 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
3934 the regression tests I'm not brave enough to enable 245.b, 245.c
3935 * doc/sdccman.lyx: added latex preamble for hyperref package.
3936 Using pdflatex this will give you a hyperlinked pdf file with
3937 bookmarks. (prepend '%' before /usepackage if this breaks something)
3939 2003-05-24 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

3949 * src/SDCCglue.c (printIval): fixed bug #739934
3951 2003-05-19 Bernhard Held <bernhard AT bernhardheld.de>
3953 Applied patch from bug 737905 (renamed yylineo to mylineno):
3960 * src/pic16/pcode.c: Cleaned warnings
3961 * src/pic16/pcodeflow.c: Cleaned warnings
3962 * src/pic16/pcoderegs.c: Cleaned warnings
3964 2003-05-19 Scott Dattalo <scott AT dattalo.com>

3973 * src/pic16/pcode.c (pic16_get_op): fixed warning on alpha
3975 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
3977 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
3978 it can be defined with CFLAGS when running configure
3979 * src/SDCCmain.c: fixed compiling + linking with object files
3981 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
3983 * configure.in: configure for pic16 port,
3984 added --disable-pic16-port
3985 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
3986 * src/SDCCmain.c: linkOptions is changed to set *,
3987 added if/endif conditional macros to remove options help
3988 messages from optionsTable when a port is not configured, added
3989 support for the PIc16 port in the ports table, when executing
3990 the compiler with no port specified on command line, a default
3991 port is selected with the new macro DEFAULT_PORT which is
3992 defined in port.h, in setDefaultOptions() linkOptions is removed
3993 from initialization assignment, since now it is a set,
3994 parseCmdLine uses setParseWithComma for linkOptions, in
3995 linkEdit() linkOptions are accessed with new function indexSet()
3996 which returns the i'th item of a set variable. See SDCCset.c, in
3997 linkEdit() when calling buildCmdLine(), added linkOptions as
3998 last argument. Now users can pass arguments to gplink via the
3999 -Wl option, main() uses pic16glue() to glue up pic16 programs
4000 * src/SDCCpeeph.c: various changes to support pic16
4001 * src/SDCCset.c: added function void *indexSet(set *, int) to

4009 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
4011 * src/pic16/glue.c: commented out some error producing lines
4012 * src/pic16/main.c: __config directives are commented out to stop
4013 gpasm complaining and test the linkage with gplink, _linkCmd and
4014 _asmCmd changed to be more gplink and gpasm friendly
4015 * src/pic16/peeph.def: peep rule 3 is commented out, since it
4016 produced an error when parsed, peep rule 12 is added to utilize
4017 movff, but it is commented out since the pCode does not support
4018 yet a command with 2 address arguments
4020 2003-05-18 <johan AT balder>
4022 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
4023 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

4047 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
4049 2003-05-11 Borut Razem <borut.razem AT siol.net>
4051 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
4052 the path of bin directory, so that PATH is the only env. variable, which has to be set
4053 in case of standard installation.
4054 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

5061 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
5063 2003-01-04 <johan AT balder>
5065 * src/SDCCval.c (getNelements): fixed the initialized array of structures
5067 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5068 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
5070 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

5078 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
5080 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
5081 * src/mcs51/main.c: removed {bindir}{sep} from aslink
5083 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5085 * in \sdcc\as\mcs51\ changed these files in order to create an
5086 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
5087 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
5088 following files to include the previous two files: aslink.dsp,
5089 Makefile.aslink, Makefile.bcc, and Makefile.in.
5091 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
5092 .adb instead of .cdb
5094 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5096 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
5097 value from option --iram-size.
5099 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5101 * \sdcc\as\mcs51\lklist.c: added boundary check before using
5104 2002-09-18 <wiml AT hhhh.org>
5106 * SDCClrange.h: exposed setFromRange() and setToRange()
5107 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
5108 packRegsForAccUse() (bug 542397)
5109 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
5110 multiple times and emitting the fetch operations more than once
5111 added aopGetUsesAcc() function to allow binary operators to
5112 fetch their operands in the correct order; made genMinus() emit
5113 compact code for X = LITERAL - Y
5115 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5116 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
5117 sprintf() in line 1267.
5119 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5120 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
5123 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5124 Changes to aslink (All the changes are marked with 'JCF'):
5126 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
5129 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
5130 area BSEG. Also moves, if possible, the DATA area down into the internal
5131 ram so more space is available.
5133 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
5136 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
5137 not bytes. Function summary() which creates a memory usage summary
5138 file with extension .mem. Reports of overlaping stack and small stack
5139 size. If the space for the stack is less than 16 bytes aslink trows a
5142 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
5143 the 8051. Option 'y' for memory summary output file.
5145 Changes to sdcc (All the changes are marked with 'JCF'):
5147 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
5149 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
5150 overlaying area for it (uses RegBankUsed[4]).
5152 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
5153 bank zero as used by default. By default aslink locates the stack
5154 (equivalent to --stack-after-data). Pass option 'y' to aslink for
5155 the creation of the .mem file. Delegates the allocation of data area
5156 to aslink (it is not longer 0x30 by default). If --stack-loc passes
5157 the begining of the stack area to aslink.
5159 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
5160 glue() in SDCCglue.c creates an area for it.
5162 2002-09-03 Borut Razem <borut.razem AT siol.net>
5163 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
5164 sdcc/src/pic/glue.c:
5165 introduced atexit() handler for teporay files removal in case of
5166 errors, assertions, ...
5168 2002-08-29 Borut Razem <borut.razem AT siol.net>
5169 * sdcc/support/cpp2/auto-host_vc_in.h:
5170 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
5171 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
5172 Maybe there is a similar problem with BORLANDC? It should be checked!
5174 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
5175 corrected improper use of assert: the assignment to clr variable was done inside the assert.
5176 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
5177 was not executed, and the compiler (cl) launched a warning:
5178 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
5180 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
5181 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
5183 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
5184 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
5186 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5187 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
5188 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
5189 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5190 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
5191 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
5192 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
5193 - added Release configuration in VS projects
5194 - review of compiler an linker options
5195 - VC .exe files are generated in bin_vc directory, not to interfere
5196 with binaries generated from other projects (cygwin, mingw, bcc ...)
5198 * sdcc/src/yacc.dsp: added
5200 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
5201 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
5202 and insert the version number definitions from .version
5204 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
5206 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
5207 added - genarate auto-host.h using auto-host_vc_in.h as template
5210 removed from CVS, generated automatically
5212 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
5213 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
5215 2002-08-11 Borut Razem <borut.razem AT siol.net>
5216 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
5218 2002-08-10 Borut Razem <borut.razem AT siol.net>
5219 * src/SDCCmain.c (main):
5220 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
5221 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
5222 The consequence was that some temporary files were not removed.
5225 unification of code in functions tempfilename() and tempfile():
5226 function tempnam() is defined in Visual Studio 6.0 and .NET

5433 * sdcc/src/SDCCloop.c:
5434 Previous fix was not good. basic blocks that have "break" or "return" are
5435 not really partof a loop , but live ranges used in these blocks should
5436 be live thru the entire loop, so set partOfLoop but don't add them to
