1828 loaded with the linker search paths (-L arguments) and the libraries
1829 to be linked with the current source (-l arguments). Changes
1830 currently will affect only the pic16 port.
1831 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
1832 include path the port specific paths and port specific libraries,

1834 * src/pic16/device.h,
1835 * src/pic16/device.c,: structure PIC_device is made public and
1836 renamed to PIC16_device, the same for variable Pics which is renamed
1837 to Pics16. Updated all references to them.
1838 * src/pic16/glue.c (pic16glue): corrected bug with code
1839 initialization which bypassed the variable initializations block.
1841 * device/lib/pic16/Makefile.rules: removed --penable-stack from
1842 COMPILE_FLAGS and added the --nostdinc option
1844 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

1851 Documenting changes from previous commits.
1852 * configure.in (version 1.56),
1853 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
1854 when generating output files to configure the pic16 library,
1855 but now I've commented it out, since gputils aren't installed in the
1856 SF compile farm, so library won't compile
1858 * device/lib/Makefile.in (version 1.56): initially I've added in
1859 target 'all' the prerequestive 'model-pic16' so it compiled the
1860 pic16 library, but now I've commented it out for the same reasons
1862 * added targets 'model-pic16' and 'objects-pic16' to compile the
1864 * added target 'port-specific-objects-pic16' to handle the
1865 generated libraries and copy them into the build/ directory
1866 * added target 'clean-intermediate-pic16' to clean intermediate
1867 files into pic16 directory
1868 * in target 'installdirs' added line to create directory pic16 in
1869 the installation path
1871 * device/include/Makefile.in (version 1.11): in target 'install'
1872 added lines to copy all header files to installation path,
1873 * in target 'installdirs' added line create directory for pic16
1874 headers in the installation path

1889 * src/z80/main.c (_parseOptions): fixed the portmode= command line
1890 option so that it actually works. Made it specific to the z80, since
1891 the gbz80 doesn't have these kinds of I/O ports.
1893 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1895 * device/include/z180.h,

1917 Mainly changes to support compilation of the device libraries
1918 * src/pic16/device.c: stack is allocated via symbol and not
1919 via literal number. The symbol is placed in the corresponding
1920 position of the data ram
1921 * (pic16_dump_section): relocatable and absolute uninitialized
1922 data are now emitted in sorted order to reduce section naming,
1923 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
1924 weren't marked as being in the access bank,
1926 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
1928 Added portion of GNU PIC Library under the directory
1929 device/include/pic16 and device/lib/pic16. These files
1930 contain the declarations of SFRs for the PIC18Fxx2 devices.
1931 The directory is initialized via configure from toplevel.
1933 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
1935 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
1936 the spilllocations to be compared correctly

1960 * doc/sdccman.lyx: Moved and added some sections, small changes
1961 all over. Telling LaTeX to be less strict with word spacing
1962 to better keep the right margin. Changed some notes about
1963 maintainance of the ports in section 3.2.1 - is it OK like this?
1965 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

2002 UPPER for immediate operands,
2003 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
2005 * src/pic16/peeph.def: all peepholes with movff are commented out,
2006 because there is a problem in the pcode peep optimizer,
2007 * src/pic16/ralloc.c: the register allocator can now reuse local

2011 Added file src/pic16/NOTES with information about program writing on
2012 the current port version.

2044 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2047 * src/z80/main.c: added missed needLinkerScript flags (more than
2048 one port structure defined in these file)
2049 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

2084 2004-01-07 Borut Razem <borut.razem AT siol.net>
2086 * support/scripts/sdcc.nsi: update PATH
2087 * support/scripts/sdcc.ico: craeted

2100 include information about variables allocated to the overlay
2103 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2105 * as/mcs51/lkmain.c: Help about -Y option

2117 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2119 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
2120 (default behaviour).
2122 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2124 A python script to validate compiler diagnostic messages. It can be
2125 used to verify that sdcc complains about bad c source code and
2126 gives a good location of the error.
2127 * support/valdiag/Makefile,
2128 * support/valdiag/valdiag.py,
2129 * support/valdiag/tests/*
2131 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

2146 Bug reported from Jesus Calvino-Fraga
2148 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
2150 * sdcc.spec: updated
2151 * device/include/Makefile.in: don't install CVS directories
2152 * device/lib/Makefile.in: added removal of CVS directories after install
2153 * doc/Makefile: fixed install, added local_icons
2154 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
2155 * src/mcs51/gen.c (genRightShift): fixed bug #870788
2156 * src/ds390/gen.c (genRightShift): fixed bug #870788
2157 * src/SDCCast.c (decorateType): fixed bug #870781
2159 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
2161 PIC16 port related changes:
2162 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
2163 added variable stackPos,
2165 * gen.c: genCall, assignResultValue: added support for
2166 pushing/retrieving function parameters to/from stack,
2167 genFunction,genEndFunction: setup stack frame for the
2169 genAddrOf: will be changed according to bug 863624
2171 * added files genutils.c and genutils.h which contain gen*
2172 debugged and optimised functions extracted from gen.c
2174 * glue.c: added variable 'externs' which holds extern symbols,
2175 pic16emitRegularMap: is modified to properly handle relocatable
2176 symbols under the new scheme,
2177 pic16createInterruptVect: is modified
2178 pic16printPublics: is modified to emit 'global' assembler directives,
2179 added pic16_printExterns to print extern symbols,
2180 pic16glue: initializes stack/frame pointer in the beginning of
2181 the assembly output. Temporary hack, will be corrected later,
2182 because gplink yet does not support stack and SDCC does not
2183 yet support a type of crt0.o object to create the final binary.
2185 * Removed many lines that contain 8051 legacy code.
2186 * The code is finally placed under a 'code' directive.
2187 * Added port specific options.
2189 * _process_pragma: simplified since now we do not need *special*
2190 include file to define SFR registers. But a separate header
2191 will be needed. This will be developed later.
2192 * _pic16_parseOptions: added, parses port specific options:
2193 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
2194 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
2195 --preplace-udata-with=
2197 * _pic16_setDefaultOptions: modified to initialize section names,
2198 but hack is temporarly out of order since it needs improvement.
2199 * _pic16_genAssemblerPreamble: configuration words are emitted by
2200 their address instead of their name. This part is incomplete and
2201 supports only the 18Fxx2 devices. Other devices will emit an error
2202 during assembly since they do not contain the same set of config
2204 * _pic16_genIVT: is modified,
2206 * pcode.c: added definitions for some hardware registers that are needed
2208 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
2209 All PCI entries are updated. Now LFSR is supported.
2210 * Removed pic16_pciTRIS is mentioned by mdubuc in source
2211 * added pic16_newpCodeOpLit2 to support instructions with
2212 two literal arguments
2213 * pic16_pCode2str: corrected code that emits assembler instructions
2214 with two literal operands and those that have an access bit modifier
2215 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
2216 this fixes a bug which caused some labels to be lost, when an
2217 assembler directive was added, i.e. banksel,
2218 * pic16_FixRegisterBanking: improved logic that causes the insertion
2220 * InlineFunction: functions that are called once, are not any more
2221 inlined. This can be a port option in the future,
2223 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
2225 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
2226 hold the corresponding uninitialized symbols,
2227 * pic16_allocProcessorRegister: registers have explicit marked the
2229 * pic16_allocInternalRegister: registers are explicit marked as
2231 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
2232 processing list, so bit registers were lost,
2235 * ralloc.h: added field 'accessBank' and original symbol operand
2236 in register definition,
2237 * removed the field isMapped from register definition,
2239 ** Several functions have been removed from various sources:
2240 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
2241 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
2242 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
2243 pic16_assignRelocatableRegisters
2245 ** others have been introduced:
2246 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
2247 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
2249 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
2251 * support/scripts/inc2h.pl: changed definition of BIT_AT
2252 to emit 'sbit at' instead of 'bit at'. This was a request.
2254 PIC16 port related preliminary changes:
2255 * gen.c: prefixed function popRegFromString with
2256 pic16_ and all references to it corrected
2257 * pcode.c: all pic16_pc_* hardware registers prefixed
2258 with underscore (_),
2259 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
2260 * ralloc.c: newReg(): when register is REG_SFR then
2261 set address to rIdx,
2262 pic16_allocProcessorRegister(): marks register wasUsed=0
2263 pic16_writeUsedRegs(): added a call to assign processor
2264 registers via pic16_assignFixedRegisters
2266 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2268 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
2269 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
2270 variables in unused register banks. Also the SSEG is placed
2271 wherever there is enough space for it, and IDATA can be anywhere
2272 in internal RAM. For now compile using -Wl-Y[stack_size].
2273 The mem file is different for this option as well, since it
2274 makes no sense of talking about DSEG lenght.
2276 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
2278 * src/SDCClrange.c: fixed bug 869095 that caused segfault
2279 in certain cases, e.g. when ROM assignment, patch provided
2280 from Albert den Haan.
2282 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

3325 A few small changes that speed up the peephole optimizer.
3329 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3331 Try to make the peephole optimizer smarter by maintaining
3332 an association between the assembly source code and the
3333 iCodes that originated them. Put this information to use
3334 with a new peephole rule condition "notVolatile" so that
3335 the rules can be aggressive yet still safe.
3340 * src/mcs51/peeph.def
3342 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3346 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
3347 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
3348 if the left or right operand symbols have the accuse flag set.
3350 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3352 Changed the type of the result of the ! (NOT) operator to char;
3353 previously it returned the same type as the source. This allows
3354 us to eliminate all the genFloatNot functions (all of its target
3355 implementations were very buggy) since !float can use the same
3358 * src/SDCCicode.c (ast2iCode): ! returns char
3359 * src/mcs51/gen.c (genNot, genNotFloat),
3360 * src/ds390/gen.c (genNot, genNotFloat),
3361 * src/z80/gen.c (genNot, genNotFloat),
3362 * src/pic/gen.c (genNot, genNotFloat),
3363 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

3367 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3368 1. Interrupt would not compile properly. Ensure PCLATH register is saved
3369 during interrupts. Ensure WSAVE is located at a shared bank address.
3370 2. Fixed page selection in some places
3371 3. Fixed BTFSS/C to where necessary use registers directly and not simply
3372 the registers name strings.
3373 4. Fixed "signed / unsigned compare" compiler warnings.
3374 5. The PIC port manages its own allocation of the general purpose
3375 registers, but makes no attempt to reuse them. As a result when
3376 compiling it soon runs out of general purpose registers. Some
3377 additional code was added to the files pcode.c and device.c to walk
3378 through the function call tree and rename the registers so that they
3388 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
3389 genPlus() & genMinus() when the result is the same as left or right
3391 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3395 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3397 Made bitfield a distinct type from bit so that bitfields
3398 convert as per ANSI C and bits retain their traditional
3399 boolean style behaviour. Implemented bitfield support in
3407 * src/ds390/gen.c: bit v bitfield split
3408 * src/z80/gen.c: New support for bitfields
3409 * support/regression/tests/bitfields.c: reenabled z80,
3412 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3414 Rules 246.x, 247.x relate to bitfields, the others speed up
3415 access to xdata mapped I/O devices.
3417 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
3419 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3421 Cleaned up genPackBits and genUnpackBits and added two helper
3422 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
3423 for literal assignments in genPackBits (thanks to Frieder for
3429 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3431 Fixed bug #748310 (pointer to function type mishandled when the
3432 function name is omitted). Also fixed a SIGSEGV when a function
3433 attribute (reentrant, etc) is used on a non-function or on a
3434 function but misplaced before the parameter list.
3436 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
3438 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
3439 * support/Util/SDCCerr.h,

3461 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3463 Made the constant following the "interrupt" keyword optional. If
3464 omitted, the function will not automatically be given an entry
3465 in the interrupt vector table (similar to #pragma NOIV, but
3466 less syntacticly kludgy). The interrupt number is also now
3467 range checked. Also fixed a bug in the high order bit example

3483 * src/SDCCsymt.c (computeType): literals are handled the same way as any
3485 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
3486 be re-activated by defining REDUCE_LITERALS)

3488 unsigned, but are signed by default
3489 * src/SDCCval.c (constVal): rearranged
3490 * src/SDCCval.c (valMod): preliminary fix
3491 * src/SDCCval.c (valCastLiteral): use TYPE_* types

3914 for a non-native english speaker.
3915 Please feel free to add to the manual or to correct my changes.

3928 * device/lib/gbz80/stubs.s
3929 * device/lib/z80/mul.s
3930 * device/lib/z80/stubs.s
3931 * src/SDCCsymt.c (initCSupport)
3933 2003-05-25 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3935 * as/mcs51/lkaomf51.c: Address space 'z' was missing.
3936 * src/avr/avr.dsp, src/ds390/ds390.dsp, src/mcs51/mcs51.dsp,
3937 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
3938 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used
3941 2003-05-25 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3943 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
3944 the regression tests I'm not brave enough to enable 245.b, 245.c
3945 * doc/sdccman.lyx: added latex preamble for hyperref package.
3946 Using pdflatex this will give you a hyperlinked pdf file with
3947 bookmarks. (prepend '%' before /usepackage if this breaks something)
3949 2003-05-24 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

3959 * src/SDCCglue.c (printIval): fixed bug #739934
3961 2003-05-19 Bernhard Held <bernhard AT bernhardheld.de>
3963 Applied patch from bug 737905 (renamed yylineo to mylineno):
3970 * src/pic16/pcode.c: Cleaned warnings
3971 * src/pic16/pcodeflow.c: Cleaned warnings
3972 * src/pic16/pcoderegs.c: Cleaned warnings

3985 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
3987 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
3988 it can be defined with CFLAGS when running configure
3989 * src/SDCCmain.c: fixed compiling + linking with object files
3991 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
3993 * configure.in: configure for pic16 port,
3994 added --disable-pic16-port
3995 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
3996 * src/SDCCmain.c: linkOptions is changed to set *,
3997 added if/endif conditional macros to remove options help
3998 messages from optionsTable when a port is not configured, added
3999 support for the PIc16 port in the ports table, when executing
4000 the compiler with no port specified on command line, a default
4001 port is selected with the new macro DEFAULT_PORT which is
4002 defined in port.h, in setDefaultOptions() linkOptions is removed
4003 from initialization assignment, since now it is a set,
4004 parseCmdLine uses setParseWithComma for linkOptions, in
4005 linkEdit() linkOptions are accessed with new function indexSet()
4006 which returns the i'th item of a set variable. See SDCCset.c, in
4007 linkEdit() when calling buildCmdLine(), added linkOptions as
4008 last argument. Now users can pass arguments to gplink via the
4009 -Wl option, main() uses pic16glue() to glue up pic16 programs
4010 * src/SDCCpeeph.c: various changes to support pic16
4011 * src/SDCCset.c: added function void *indexSet(set *, int) to

4019 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
4021 * src/pic16/glue.c: commented out some error producing lines
4022 * src/pic16/main.c: __config directives are commented out to stop
4023 gpasm complaining and test the linkage with gplink, _linkCmd and
4024 _asmCmd changed to be more gplink and gpasm friendly
4025 * src/pic16/peeph.def: peep rule 3 is commented out, since it
4026 produced an error when parsed, peep rule 12 is added to utilize
4027 movff, but it is commented out since the pCode does not support
4028 yet a command with 2 address arguments
4030 2003-05-18 <johan AT balder>
4032 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
4033 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

4057 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
4059 2003-05-11 Borut Razem <borut.razem AT siol.net>
4061 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
4062 the path of bin directory, so that PATH is the only env. variable, which has to be set
4063 in case of standard installation.
4064 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

5093 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5095 * in \sdcc\as\mcs51\ changed these files in order to create an
5096 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
5097 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
5098 following files to include the previous two files: aslink.dsp,
5099 Makefile.aslink, Makefile.bcc, and Makefile.in.
5101 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
5102 .adb instead of .cdb
5104 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5106 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
5107 value from option --iram-size.
5109 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5111 * \sdcc\as\mcs51\lklist.c: added boundary check before using
5114 2002-09-18 <wiml AT hhhh.org>
5116 * SDCClrange.h: exposed setFromRange() and setToRange()
5117 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
5118 packRegsForAccUse() (bug 542397)
5119 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
5120 multiple times and emitting the fetch operations more than once
5121 added aopGetUsesAcc() function to allow binary operators to
5122 fetch their operands in the correct order; made genMinus() emit
5123 compact code for X = LITERAL - Y
5125 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5126 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
5127 sprintf() in line 1267.
5129 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5130 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
5133 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5134 Changes to aslink (All the changes are marked with 'JCF'):
5136 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
5139 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
5140 area BSEG. Also moves, if possible, the DATA area down into the internal
5141 ram so more space is available.
5143 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
5146 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
5147 not bytes. Function summary() which creates a memory usage summary
5148 file with extension .mem. Reports of overlaping stack and small stack
5149 size. If the space for the stack is less than 16 bytes aslink trows a
5152 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
5153 the 8051. Option 'y' for memory summary output file.
5155 Changes to sdcc (All the changes are marked with 'JCF'):
5157 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
5159 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
5160 overlaying area for it (uses RegBankUsed[4]).
5162 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
5163 bank zero as used by default. By default aslink locates the stack
5164 (equivalent to --stack-after-data). Pass option 'y' to aslink for
5165 the creation of the .mem file. Delegates the allocation of data area
5166 to aslink (it is not longer 0x30 by default). If --stack-loc passes
5167 the begining of the stack area to aslink.
5169 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
5170 glue() in SDCCglue.c creates an area for it.
5172 2002-09-03 Borut Razem <borut.razem AT siol.net>
5173 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
5174 sdcc/src/pic/glue.c:
5175 introduced atexit() handler for teporay files removal in case of
5176 errors, assertions, ...
5178 2002-08-29 Borut Razem <borut.razem AT siol.net>
5179 * sdcc/support/cpp2/auto-host_vc_in.h:
5180 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
5181 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
5182 Maybe there is a similar problem with BORLANDC? It should be checked!
5184 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
5185 corrected improper use of assert: the assignment to clr variable was done inside the assert.
5186 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
5187 was not executed, and the compiler (cl) launched a warning:
5188 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
5190 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>

5208 * sdcc/src/yacc.dsp: added
5210 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:

5223 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
5225 2002-08-11 Borut Razem <borut.razem AT siol.net>
5226 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
5228 2002-08-10 Borut Razem <borut.razem AT siol.net>
5229 * src/SDCCmain.c (main):
5230 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
5231 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
5232 The consequence was that some temporary files were not removed.
5235 unification of code in functions tempfilename() and tempfile():
5236 function tempnam() is defined in Visual Studio 6.0 and .NET
5238 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
5240 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5241 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
5242 - removed compiler command line option /WX: Treats all warnings as errors
5243 - update a list of source files, included into the project
5245 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5246 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
5247 changed project type to Generic Project so that can be correcly converted to VS.NET project
5249 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
5251 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

5255 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
5256 added return 0 statements after assert() to make compiler happy
5258 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
5259 added newline in the def file to keep MSC compiler satisfied
5261 * sdcc/src/z80/gen.c:
5262 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
5263 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
5264 - solved MSC error in function aopDump()
5266 * sdcc_vc.h: define PREFIX as "\\sdcc"
5268 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

5324 were not getting allocated.
5326 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
5329 Fixed left shift. Will promote the left side of a left shift
5330 if a) left shifting more than size of operand or b) when assigned
5331 to something size > size of left side
5333 2002-03-14 Scott Dattalo <scott AT dattalo.com>

5443 * sdcc/src/SDCCloop.c:
5444 Previous fix was not good. basic blocks that have "break" or "return" are
5445 not really partof a loop , but live ranges used in these blocks should
5446 be live thru the entire loop, so set partOfLoop but don't add them to
5449 2002-02-21 <johan AT FRIJA>
