1824 loaded with the linker search paths (-L arguments) and the libraries
1825 to be linked with the current source (-l arguments). Changes
1826 currently will affect only the pic16 port.
1827 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
1828 include path the port specific paths and port specific libraries,
1829 * gplink command now contains the $3 argument,

1834 * src/pic16/glue.c (pic16glue): corrected bug with code
1835 initialization which bypassed the variable initializations block.
1837 * device/lib/pic16/Makefile.rules: removed --penable-stack from
1838 COMPILE_FLAGS and added the --nostdinc option
1840 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1842 * device/include/mc68hc908jb8.h: Register defs for another member

1845 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
1847 Documenting changes from previous commits.
1848 * configure.in (version 1.56),
1849 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
1850 when generating output files to configure the pic16 library,
1851 but now I've commented it out, since gputils aren't installed in the
1852 SF compile farm, so library won't compile
1854 * device/lib/Makefile.in (version 1.56): initially I've added in
1855 target 'all' the prerequestive 'model-pic16' so it compiled the
1856 pic16 library, but now I've commented it out for the same reasons
1858 * added targets 'model-pic16' and 'objects-pic16' to compile the
1860 * added target 'port-specific-objects-pic16' to handle the
1861 generated libraries and copy them into the build/ directory
1862 * added target 'clean-intermediate-pic16' to clean intermediate
1863 files into pic16 directory
1864 * in target 'installdirs' added line to create directory pic16 in
1865 the installation path
1867 * device/include/Makefile.in (version 1.11): in target 'install'
1868 added lines to copy all header files to installation path,
1869 * in target 'installdirs' added line create directory for pic16
1870 headers in the installation path

1885 * src/z80/main.c (_parseOptions): fixed the portmode= command line
1886 option so that it actually works. Made it specific to the z80, since
1887 the gbz80 doesn't have these kinds of I/O ports.
1889 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1891 * device/include/z180.h,

1913 Mainly changes to support compilation of the device libraries
1914 * src/pic16/device.c: stack is allocated via symbol and not
1915 via literal number. The symbol is placed in the corresponding
1916 position of the data ram
1917 * (pic16_dump_section): relocatable and absolute uninitialized
1918 data are now emitted in sorted order to reduce section naming,
1919 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
1920 weren't marked as being in the access bank,
1922 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
1924 Added portion of GNU PIC Library under the directory
1925 device/include/pic16 and device/lib/pic16. These files
1926 contain the declarations of SFRs for the PIC18Fxx2 devices.
1927 The directory is initialized via configure from toplevel.
1929 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
1931 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
1932 the spilllocations to be compared correctly

1956 * doc/sdccman.lyx: Moved and added some sections, small changes
1957 all over. Telling LaTeX to be less strict with word spacing
1958 to better keep the right margin. Changed some notes about
1959 maintainance of the ports in section 3.2.1 - is it OK like this?
1961 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

1998 UPPER for immediate operands,
1999 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
2001 * src/pic16/peeph.def: all peepholes with movff are commented out,
2002 because there is a problem in the pcode peep optimizer,
2003 * src/pic16/ralloc.c: the register allocator can now reuse local

2005 * src/pic16/ralloc.h: added flag isLocal in structure regs,
2007 Added file src/pic16/NOTES with information about program writing on
2008 the current port version.

2040 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2043 * src/z80/main.c: added missed needLinkerScript flags (more than
2044 one port structure defined in these file)
2045 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

2080 2004-01-07 Borut Razem <borut.razem AT siol.net>
2082 * support/scripts/sdcc.nsi: update PATH
2083 * support/scripts/sdcc.ico: craeted

2096 include information about variables allocated to the overlay
2099 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2101 * as/mcs51/lkmain.c: Help about -Y option

2113 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2115 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
2116 (default behaviour).
2118 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2120 A python script to validate compiler diagnostic messages. It can be
2121 used to verify that sdcc complains about bad c source code and
2122 gives a good location of the error.
2123 * support/valdiag/Makefile,
2124 * support/valdiag/valdiag.py,
2125 * support/valdiag/tests/*
2127 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

2142 Bug reported from Jesus Calvino-Fraga
2144 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
2146 * sdcc.spec: updated
2147 * device/include/Makefile.in: don't install CVS directories
2148 * device/lib/Makefile.in: added removal of CVS directories after install
2149 * doc/Makefile: fixed install, added local_icons
2150 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
2151 * src/mcs51/gen.c (genRightShift): fixed bug #870788
2152 * src/ds390/gen.c (genRightShift): fixed bug #870788
2153 * src/SDCCast.c (decorateType): fixed bug #870781
2155 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
2157 PIC16 port related changes:
2158 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
2159 added variable stackPos,
2161 * gen.c: genCall, assignResultValue: added support for
2162 pushing/retrieving function parameters to/from stack,
2163 genFunction,genEndFunction: setup stack frame for the
2165 genAddrOf: will be changed according to bug 863624
2167 * added files genutils.c and genutils.h which contain gen*
2168 debugged and optimised functions extracted from gen.c
2170 * glue.c: added variable 'externs' which holds extern symbols,
2171 pic16emitRegularMap: is modified to properly handle relocatable
2172 symbols under the new scheme,
2173 pic16createInterruptVect: is modified
2174 pic16printPublics: is modified to emit 'global' assembler directives,
2175 added pic16_printExterns to print extern symbols,
2176 pic16glue: initializes stack/frame pointer in the beginning of
2177 the assembly output. Temporary hack, will be corrected later,
2178 because gplink yet does not support stack and SDCC does not
2179 yet support a type of crt0.o object to create the final binary.
2181 * Removed many lines that contain 8051 legacy code.
2182 * The code is finally placed under a 'code' directive.
2183 * Added port specific options.
2185 * _process_pragma: simplified since now we do not need *special*
2186 include file to define SFR registers. But a separate header
2187 will be needed. This will be developed later.
2188 * _pic16_parseOptions: added, parses port specific options:
2189 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
2190 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
2191 --preplace-udata-with=
2193 * _pic16_setDefaultOptions: modified to initialize section names,
2194 but hack is temporarly out of order since it needs improvement.
2195 * _pic16_genAssemblerPreamble: configuration words are emitted by
2196 their address instead of their name. This part is incomplete and
2197 supports only the 18Fxx2 devices. Other devices will emit an error
2198 during assembly since they do not contain the same set of config
2200 * _pic16_genIVT: is modified,
2202 * pcode.c: added definitions for some hardware registers that are needed
2204 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
2205 All PCI entries are updated. Now LFSR is supported.
2206 * Removed pic16_pciTRIS is mentioned by mdubuc in source
2207 * added pic16_newpCodeOpLit2 to support instructions with
2208 two literal arguments
2209 * pic16_pCode2str: corrected code that emits assembler instructions
2210 with two literal operands and those that have an access bit modifier
2211 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
2212 this fixes a bug which caused some labels to be lost, when an
2213 assembler directive was added, i.e. banksel,
2214 * pic16_FixRegisterBanking: improved logic that causes the insertion
2216 * InlineFunction: functions that are called once, are not any more
2217 inlined. This can be a port option in the future,
2219 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
2221 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
2222 hold the corresponding uninitialized symbols,
2223 * pic16_allocProcessorRegister: registers have explicit marked the
2225 * pic16_allocInternalRegister: registers are explicit marked as
2227 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
2228 processing list, so bit registers were lost,
2231 * ralloc.h: added field 'accessBank' and original symbol operand
2232 in register definition,
2233 * removed the field isMapped from register definition,
2235 ** Several functions have been removed from various sources:
2236 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
2237 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
2238 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
2239 pic16_assignRelocatableRegisters
2241 ** others have been introduced:
2242 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
2243 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
2245 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
2247 * support/scripts/inc2h.pl: changed definition of BIT_AT
2248 to emit 'sbit at' instead of 'bit at'. This was a request.
2250 PIC16 port related preliminary changes:
2251 * gen.c: prefixed function popRegFromString with
2252 pic16_ and all references to it corrected
2253 * pcode.c: all pic16_pc_* hardware registers prefixed
2254 with underscore (_),
2255 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
2256 * ralloc.c: newReg(): when register is REG_SFR then
2257 set address to rIdx,
2258 pic16_allocProcessorRegister(): marks register wasUsed=0
2259 pic16_writeUsedRegs(): added a call to assign processor
2260 registers via pic16_assignFixedRegisters
2262 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2264 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
2265 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
2266 variables in unused register banks. Also the SSEG is placed
2267 wherever there is enough space for it, and IDATA can be anywhere
2268 in internal RAM. For now compile using -Wl-Y[stack_size].
2269 The mem file is different for this option as well, since it
2270 makes no sense of talking about DSEG lenght.
2272 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
2274 * src/SDCClrange.c: fixed bug 869095 that caused segfault
2275 in certain cases, e.g. when ROM assignment, patch provided
2276 from Albert den Haan.
2278 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

3321 A few small changes that speed up the peephole optimizer.
3325 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3327 Try to make the peephole optimizer smarter by maintaining
3328 an association between the assembly source code and the
3329 iCodes that originated them. Put this information to use
3330 with a new peephole rule condition "notVolatile" so that
3331 the rules can be aggressive yet still safe.
3336 * src/mcs51/peeph.def
3338 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3342 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
3343 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
3344 if the left or right operand symbols have the accuse flag set.
3346 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3348 Changed the type of the result of the ! (NOT) operator to char;
3349 previously it returned the same type as the source. This allows
3350 us to eliminate all the genFloatNot functions (all of its target
3351 implementations were very buggy) since !float can use the same
3354 * src/SDCCicode.c (ast2iCode): ! returns char
3355 * src/mcs51/gen.c (genNot, genNotFloat),
3356 * src/ds390/gen.c (genNot, genNotFloat),
3357 * src/z80/gen.c (genNot, genNotFloat),
3358 * src/pic/gen.c (genNot, genNotFloat),
3359 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

3363 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3364 1. Interrupt would not compile properly. Ensure PCLATH register is saved
3365 during interrupts. Ensure WSAVE is located at a shared bank address.
3366 2. Fixed page selection in some places
3367 3. Fixed BTFSS/C to where necessary use registers directly and not simply
3368 the registers name strings.
3369 4. Fixed "signed / unsigned compare" compiler warnings.
3370 5. The PIC port manages its own allocation of the general purpose
3371 registers, but makes no attempt to reuse them. As a result when
3372 compiling it soon runs out of general purpose registers. Some
3373 additional code was added to the files pcode.c and device.c to walk
3374 through the function call tree and rename the registers so that they
3384 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
3385 genPlus() & genMinus() when the result is the same as left or right

3391 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3393 Made bitfield a distinct type from bit so that bitfields
3394 convert as per ANSI C and bits retain their traditional
3395 boolean style behaviour. Implemented bitfield support in
3403 * src/ds390/gen.c: bit v bitfield split
3404 * src/z80/gen.c: New support for bitfields
3405 * support/regression/tests/bitfields.c: reenabled z80,
3408 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3410 Rules 246.x, 247.x relate to bitfields, the others speed up
3411 access to xdata mapped I/O devices.
3413 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
3415 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3417 Cleaned up genPackBits and genUnpackBits and added two helper
3418 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
3419 for literal assignments in genPackBits (thanks to Frieder for
3425 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3427 Fixed bug #748310 (pointer to function type mishandled when the
3428 function name is omitted). Also fixed a SIGSEGV when a function
3429 attribute (reentrant, etc) is used on a non-function or on a
3430 function but misplaced before the parameter list.
3432 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
3434 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

3457 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3459 Made the constant following the "interrupt" keyword optional. If
3460 omitted, the function will not automatically be given an entry
3461 in the interrupt vector table (similar to #pragma NOIV, but
3462 less syntacticly kludgy). The interrupt number is also now
3463 range checked. Also fixed a bug in the high order bit example

3477 * src/SDCCicode.c (operandOperation): rewritten some ops
3478 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
3479 * src/SDCCsymt.c (computeType): literals are handled the same way as any
3481 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
3482 be re-activated by defining REDUCE_LITERALS)

3484 unsigned, but are signed by default
3485 * src/SDCCval.c (constVal): rearranged
3486 * src/SDCCval.c (valMod): preliminary fix
3487 * src/SDCCval.c (valCastLiteral): use TYPE_* types

3932 * src/avr/avr.dsp, src/ds390/ds390.dsp, src/mcs51/mcs51.dsp,
3933 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
3934 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used
3937 2003-05-25 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3939 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
3940 the regression tests I'm not brave enough to enable 245.b, 245.c
3941 * doc/sdccman.lyx: added latex preamble for hyperref package.
3942 Using pdflatex this will give you a hyperlinked pdf file with
3943 bookmarks. (prepend '%' before /usepackage if this breaks something)

3955 * src/SDCCglue.c (printIval): fixed bug #739934
3957 2003-05-19 Bernhard Held <bernhard AT bernhardheld.de>
3959 Applied patch from bug 737905 (renamed yylineo to mylineno):
3966 * src/pic16/pcode.c: Cleaned warnings
3967 * src/pic16/pcodeflow.c: Cleaned warnings
3968 * src/pic16/pcoderegs.c: Cleaned warnings
3970 2003-05-19 Scott Dattalo <scott AT dattalo.com>

3981 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
3983 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
3984 it can be defined with CFLAGS when running configure
3985 * src/SDCCmain.c: fixed compiling + linking with object files
3987 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
3989 * configure.in: configure for pic16 port,
3990 added --disable-pic16-port
3991 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
3992 * src/SDCCmain.c: linkOptions is changed to set *,
3993 added if/endif conditional macros to remove options help
3994 messages from optionsTable when a port is not configured, added
3995 support for the PIc16 port in the ports table, when executing
3996 the compiler with no port specified on command line, a default
3997 port is selected with the new macro DEFAULT_PORT which is
3998 defined in port.h, in setDefaultOptions() linkOptions is removed
3999 from initialization assignment, since now it is a set,
4000 parseCmdLine uses setParseWithComma for linkOptions, in
4001 linkEdit() linkOptions are accessed with new function indexSet()
4002 which returns the i'th item of a set variable. See SDCCset.c, in
4003 linkEdit() when calling buildCmdLine(), added linkOptions as
4004 last argument. Now users can pass arguments to gplink via the
4005 -Wl option, main() uses pic16glue() to glue up pic16 programs
4006 * src/SDCCpeeph.c: various changes to support pic16
4007 * src/SDCCset.c: added function void *indexSet(set *, int) to

4015 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
4017 * src/pic16/glue.c: commented out some error producing lines
4018 * src/pic16/main.c: __config directives are commented out to stop
4019 gpasm complaining and test the linkage with gplink, _linkCmd and
4020 _asmCmd changed to be more gplink and gpasm friendly
4021 * src/pic16/peeph.def: peep rule 3 is commented out, since it
4022 produced an error when parsed, peep rule 12 is added to utilize
4023 movff, but it is commented out since the pCode does not support
4024 yet a command with 2 address arguments
4026 2003-05-18 <johan AT balder>
4028 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
4029 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT
4030 2003-05-17 Karl Bongers(apply patches from Martin Helmling)

4053 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
4055 2003-05-11 Borut Razem <borut.razem AT siol.net>
4057 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
4058 the path of bin directory, so that PATH is the only env. variable, which has to be set
4059 in case of standard installation.
4060 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

5063 * src/SDCCicode.c: fixed array add
5065 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>

5067 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
5069 2003-01-04 <johan AT balder>
5071 * src/SDCCval.c (getNelements): fixed the initialized array of structures
5073 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5074 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
5076 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
5077 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

5086 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
5087 * src/mcs51/main.c: removed {bindir}{sep} from aslink
5089 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5091 * in \sdcc\as\mcs51\ changed these files in order to create an
5092 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
5093 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
5094 following files to include the previous two files: aslink.dsp,
5095 Makefile.aslink, Makefile.bcc, and Makefile.in.
5097 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
5098 .adb instead of .cdb
5100 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5102 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
5103 value from option --iram-size.
5105 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5107 * \sdcc\as\mcs51\lklist.c: added boundary check before using
5110 2002-09-18 <wiml AT hhhh.org>
5112 * SDCClrange.h: exposed setFromRange() and setToRange()
5113 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
5114 packRegsForAccUse() (bug 542397)
5115 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
5116 multiple times and emitting the fetch operations more than once
5117 added aopGetUsesAcc() function to allow binary operators to
5118 fetch their operands in the correct order; made genMinus() emit
5119 compact code for X = LITERAL - Y
5121 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5122 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
5123 sprintf() in line 1267.
5125 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5126 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
5129 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5130 Changes to aslink (All the changes are marked with 'JCF'):
5132 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
5135 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
5136 area BSEG. Also moves, if possible, the DATA area down into the internal
5137 ram so more space is available.
5139 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
5142 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
5143 not bytes. Function summary() which creates a memory usage summary
5144 file with extension .mem. Reports of overlaping stack and small stack
5145 size. If the space for the stack is less than 16 bytes aslink trows a
5148 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
5149 the 8051. Option 'y' for memory summary output file.
5151 Changes to sdcc (All the changes are marked with 'JCF'):
5153 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
5155 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
5156 overlaying area for it (uses RegBankUsed[4]).
5158 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
5159 bank zero as used by default. By default aslink locates the stack
5160 (equivalent to --stack-after-data). Pass option 'y' to aslink for
5161 the creation of the .mem file. Delegates the allocation of data area
5162 to aslink (it is not longer 0x30 by default). If --stack-loc passes
5163 the begining of the stack area to aslink.
5165 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
5166 glue() in SDCCglue.c creates an area for it.
5168 2002-09-03 Borut Razem <borut.razem AT siol.net>
5169 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
5170 sdcc/src/pic/glue.c:
5171 introduced atexit() handler for teporay files removal in case of
5172 errors, assertions, ...
5174 2002-08-29 Borut Razem <borut.razem AT siol.net>
5175 * sdcc/support/cpp2/auto-host_vc_in.h:
5176 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
5177 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
5178 Maybe there is a similar problem with BORLANDC? It should be checked!
5180 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
5181 corrected improper use of assert: the assignment to clr variable was done inside the assert.
5182 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
5183 was not executed, and the compiler (cl) launched a warning:
5184 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
5186 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
5187 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
5189 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
5190 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
5192 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5193 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
5194 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
5195 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5196 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
5197 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
5198 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
5199 - added Release configuration in VS projects
5200 - review of compiler an linker options
5201 - VC .exe files are generated in bin_vc directory, not to interfere
5202 with binaries generated from other projects (cygwin, mingw, bcc ...)
5204 * sdcc/src/yacc.dsp: added
5206 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
5207 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
5208 and insert the version number definitions from .version
5210 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
5212 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
5213 added - genarate auto-host.h using auto-host_vc_in.h as template
5216 removed from CVS, generated automatically
5218 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
5219 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
5221 2002-08-11 Borut Razem <borut.razem AT siol.net>
5222 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
5224 2002-08-10 Borut Razem <borut.razem AT siol.net>
5225 * src/SDCCmain.c (main):
5226 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
5227 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
5228 The consequence was that some temporary files were not removed.
5231 unification of code in functions tempfilename() and tempfile():
5232 function tempnam() is defined in Visual Studio 6.0 and .NET
5234 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
5236 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5237 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
5238 - removed compiler command line option /WX: Treats all warnings as errors
5239 - update a list of source files, included into the project
5241 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,

5254 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
5255 added newline in the def file to keep MSC compiler satisfied
5257 * sdcc/src/z80/gen.c:
5258 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
5259 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
5260 - solved MSC error in function aopDump()

5439 * sdcc/src/SDCCloop.c:
5440 Previous fix was not good. basic blocks that have "break" or "return" are
5441 not really partof a loop , but live ranges used in these blocks should
