1847 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
1849 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
1850 loaded with the linker search paths (-L arguments) and the libraries
1851 to be linked with the current source (-l arguments). Changes
1852 currently will affect only the pic16 port.
1853 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
1854 include path the port specific paths and port specific libraries,
1855 * gplink command now contains the $3 argument,
1856 * src/pic16/device.h,
1857 * src/pic16/device.c,: structure PIC_device is made public and
1858 renamed to PIC16_device, the same for variable Pics which is renamed
1859 to Pics16. Updated all references to them.
1860 * src/pic16/glue.c (pic16glue): corrected bug with code
1861 initialization which bypassed the variable initializations block.

1871 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
1873 Documenting changes from previous commits.
1874 * configure.in (version 1.56),
1875 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
1876 when generating output files to configure the pic16 library,
1877 but now I've commented it out, since gputils aren't installed in the
1878 SF compile farm, so library won't compile
1880 * device/lib/Makefile.in (version 1.56): initially I've added in
1881 target 'all' the prerequestive 'model-pic16' so it compiled the
1882 pic16 library, but now I've commented it out for the same reasons
1884 * added targets 'model-pic16' and 'objects-pic16' to compile the
1886 * added target 'port-specific-objects-pic16' to handle the
1887 generated libraries and copy them into the build/ directory
1888 * added target 'clean-intermediate-pic16' to clean intermediate
1889 files into pic16 directory
1890 * in target 'installdirs' added line to create directory pic16 in
1891 the installation path
1893 * device/include/Makefile.in (version 1.11): in target 'install'
1894 added lines to copy all header files to installation path,
1895 * in target 'installdirs' added line create directory for pic16
1896 headers in the installation path

1911 * src/z80/main.c (_parseOptions): fixed the portmode= command line
1912 option so that it actually works. Made it specific to the z80, since
1913 the gbz80 doesn't have these kinds of I/O ports.
1915 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1917 * device/include/z180.h,

1939 Mainly changes to support compilation of the device libraries
1940 * src/pic16/device.c: stack is allocated via symbol and not
1941 via literal number. The symbol is placed in the corresponding
1942 position of the data ram
1943 * (pic16_dump_section): relocatable and absolute uninitialized
1944 data are now emitted in sorted order to reduce section naming,
1945 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
1946 weren't marked as being in the access bank,
1948 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
1950 Added portion of GNU PIC Library under the directory
1951 device/include/pic16 and device/lib/pic16. These files
1952 contain the declarations of SFRs for the PIC18Fxx2 devices.
1953 The directory is initialized via configure from toplevel.
1955 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
1957 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
1958 the spilllocations to be compared correctly
1960 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
1962 * src/SDCCast.c (decorateType): fixed bug introduced today
1964 2004-01-12 Borut Razem <borut.razem AT siol.net>

1982 * doc/sdccman.lyx: Moved and added some sections, small changes
1983 all over. Telling LaTeX to be less strict with word spacing
1984 to better keep the right margin. Changed some notes about
1985 maintainance of the ports in section 3.2.1 - is it OK like this?
1987 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

2024 UPPER for immediate operands,
2025 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
2027 * src/pic16/peeph.def: all peepholes with movff are commented out,
2028 because there is a problem in the pcode peep optimizer,
2029 * src/pic16/ralloc.c: the register allocator can now reuse local

2031 * src/pic16/ralloc.h: added flag isLocal in structure regs,
2033 Added file src/pic16/NOTES with information about program writing on
2034 the current port version.

2043 * src/SDCCmain.c : fixed #872250: -l command line defined library
2044 files are scanned before standard library files
2046 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

2066 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2069 * src/z80/main.c: added missed needLinkerScript flags (more than
2070 one port structure defined in these file)
2071 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed
2074 2004-01-08 Vangelis Rokas <vrokas AT otenet.gr>

2087 needLinkerScript flag
2089 * src/pic16/gen.c (genAddrOf): fixed bug #863624
2090 * src/pic/glue.c: added variable udata_section_name to
2091 override default uninitialized data segment definition for
2092 devices only with SHAREBANK memory (reported from Erik Epetrich)
2093 * (pic14emitOverlay): modified to emit a commented overlay segment
2094 directive when no overlay data exist
2095 * (picglue): modified to emit uninitialized data segment
2096 according to udata_section_name

2106 2004-01-07 Borut Razem <borut.razem AT siol.net>
2108 * support/scripts/sdcc.nsi: update PATH
2109 * support/scripts/sdcc.ico: craeted
2111 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>

2122 include information about variables allocated to the overlay
2125 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2127 * as/mcs51/lkmain.c: Help about -Y option

2137 LEFT_OP (left shift)
2139 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2141 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
2142 (default behaviour).
2144 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2146 A python script to validate compiler diagnostic messages. It can be
2147 used to verify that sdcc complains about bad c source code and
2148 gives a good location of the error.
2149 * support/valdiag/Makefile,
2150 * support/valdiag/valdiag.py,
2151 * support/valdiag/tests/*
2153 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2155 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
2156 * src/SDCCsymt.c (newEnumType),

2164 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
2166 * src/common.h: added ifndef/define/endif macros
2167 around the header file.
2168 Bug reported from Jesus Calvino-Fraga
2170 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
2172 * sdcc.spec: updated
2173 * device/include/Makefile.in: don't install CVS directories
2174 * device/lib/Makefile.in: added removal of CVS directories after install
2175 * doc/Makefile: fixed install, added local_icons
2176 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
2177 * src/mcs51/gen.c (genRightShift): fixed bug #870788
2178 * src/ds390/gen.c (genRightShift): fixed bug #870788
2179 * src/SDCCast.c (decorateType): fixed bug #870781
2181 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
2183 PIC16 port related changes:
2184 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
2185 added variable stackPos,
2187 * gen.c: genCall, assignResultValue: added support for
2188 pushing/retrieving function parameters to/from stack,
2189 genFunction,genEndFunction: setup stack frame for the
2191 genAddrOf: will be changed according to bug 863624
2193 * added files genutils.c and genutils.h which contain gen*
2194 debugged and optimised functions extracted from gen.c
2196 * glue.c: added variable 'externs' which holds extern symbols,
2197 pic16emitRegularMap: is modified to properly handle relocatable
2198 symbols under the new scheme,
2199 pic16createInterruptVect: is modified
2200 pic16printPublics: is modified to emit 'global' assembler directives,
2201 added pic16_printExterns to print extern symbols,
2202 pic16glue: initializes stack/frame pointer in the beginning of
2203 the assembly output. Temporary hack, will be corrected later,
2204 because gplink yet does not support stack and SDCC does not
2205 yet support a type of crt0.o object to create the final binary.
2207 * Removed many lines that contain 8051 legacy code.
2208 * The code is finally placed under a 'code' directive.
2209 * Added port specific options.
2211 * _process_pragma: simplified since now we do not need *special*
2212 include file to define SFR registers. But a separate header
2213 will be needed. This will be developed later.
2214 * _pic16_parseOptions: added, parses port specific options:
2215 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
2216 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
2217 --preplace-udata-with=
2219 * _pic16_setDefaultOptions: modified to initialize section names,
2220 but hack is temporarly out of order since it needs improvement.
2221 * _pic16_genAssemblerPreamble: configuration words are emitted by
2222 their address instead of their name. This part is incomplete and
2223 supports only the 18Fxx2 devices. Other devices will emit an error
2224 during assembly since they do not contain the same set of config
2226 * _pic16_genIVT: is modified,
2228 * pcode.c: added definitions for some hardware registers that are needed
2230 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
2231 All PCI entries are updated. Now LFSR is supported.
2232 * Removed pic16_pciTRIS is mentioned by mdubuc in source
2233 * added pic16_newpCodeOpLit2 to support instructions with
2234 two literal arguments
2235 * pic16_pCode2str: corrected code that emits assembler instructions
2236 with two literal operands and those that have an access bit modifier
2237 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
2238 this fixes a bug which caused some labels to be lost, when an
2239 assembler directive was added, i.e. banksel,
2240 * pic16_FixRegisterBanking: improved logic that causes the insertion
2242 * InlineFunction: functions that are called once, are not any more
2243 inlined. This can be a port option in the future,
2245 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
2247 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
2248 hold the corresponding uninitialized symbols,
2249 * pic16_allocProcessorRegister: registers have explicit marked the
2251 * pic16_allocInternalRegister: registers are explicit marked as
2253 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
2254 processing list, so bit registers were lost,
2257 * ralloc.h: added field 'accessBank' and original symbol operand
2258 in register definition,
2259 * removed the field isMapped from register definition,
2261 ** Several functions have been removed from various sources:
2262 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
2263 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
2264 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
2265 pic16_assignRelocatableRegisters
2267 ** others have been introduced:
2268 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
2269 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
2271 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
2273 * support/scripts/inc2h.pl: changed definition of BIT_AT
2274 to emit 'sbit at' instead of 'bit at'. This was a request.
2276 PIC16 port related preliminary changes:
2277 * gen.c: prefixed function popRegFromString with
2278 pic16_ and all references to it corrected
2279 * pcode.c: all pic16_pc_* hardware registers prefixed
2280 with underscore (_),
2281 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
2282 * ralloc.c: newReg(): when register is REG_SFR then
2283 set address to rIdx,
2284 pic16_allocProcessorRegister(): marks register wasUsed=0
2285 pic16_writeUsedRegs(): added a call to assign processor
2286 registers via pic16_assignFixedRegisters
2288 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2290 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
2291 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
2292 variables in unused register banks. Also the SSEG is placed
2293 wherever there is enough space for it, and IDATA can be anywhere
2294 in internal RAM. For now compile using -Wl-Y[stack_size].
2295 The mem file is different for this option as well, since it
2296 makes no sense of talking about DSEG lenght.
2298 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
2300 * src/SDCClrange.c: fixed bug 869095 that caused segfault
2301 in certain cases, e.g. when ROM assignment, patch provided
2302 from Albert den Haan.
2304 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>
2306 Many signedness and type propagation fixes:
2307 * src/SDCCicode.c: made geniCodeCast() static
2308 replaced SPEC_ by IS_ (cosmetic)
2309 (operandOperation): fixed div and mod operation
2310 (usualBinaryConversions): added support for promotion of char
2311 (geniCodeMultiply): replaced (unsigned long) by (TYPE_UDWORD)
2312 (geniCodeDivision): replaced (unsigned long) by (TYPE_UDWORD)
2313 (geniCodeAdd): an array index will stay unsigned, even if promoted
2315 (geniCodeArray): ditto
2316 * src/SDCCicode.h: made geniCodeCast() static: removed prototype

3310 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
3311 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
3312 If they pop r0/r1 they must be called in the opposite order than aopOp().
3313 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
3314 (resp. --stack-auto), prepared for --xstack

3320 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
3322 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
3323 these ports have their own __sdcc_external_start()
3325 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
3327 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3328 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
3329 type for bits was changed. It resulted in bit variables becoming
3330 global, which is not permitted in PIC 14 assembly output.
3332 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3334 * doc/sdccman.lyx: various additions and updates. Rearranged sections
3336 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3338 Z80 and MCS51 linkers complaint if a public symbol is defined

3347 A few small changes that speed up the peephole optimizer.
3351 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3353 Try to make the peephole optimizer smarter by maintaining
3354 an association between the assembly source code and the
3355 iCodes that originated them. Put this information to use
3356 with a new peephole rule condition "notVolatile" so that
3357 the rules can be aggressive yet still safe.
3362 * src/mcs51/peeph.def
3364 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3368 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
3369 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
3370 if the left or right operand symbols have the accuse flag set.
3372 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3374 Changed the type of the result of the ! (NOT) operator to char;
3375 previously it returned the same type as the source. This allows
3376 us to eliminate all the genFloatNot functions (all of its target
3377 implementations were very buggy) since !float can use the same
3380 * src/SDCCicode.c (ast2iCode): ! returns char

3382 * src/ds390/gen.c (genNot, genNotFloat),
3383 * src/z80/gen.c (genNot, genNotFloat),
3384 * src/pic/gen.c (genNot, genNotFloat),
3385 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

3389 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3390 1. Interrupt would not compile properly. Ensure PCLATH register is saved
3391 during interrupts. Ensure WSAVE is located at a shared bank address.
3392 2. Fixed page selection in some places
3393 3. Fixed BTFSS/C to where necessary use registers directly and not simply
3394 the registers name strings.
3395 4. Fixed "signed / unsigned compare" compiler warnings.
3396 5. The PIC port manages its own allocation of the general purpose
3397 registers, but makes no attempt to reuse them. As a result when
3398 compiling it soon runs out of general purpose registers. Some
3399 additional code was added to the files pcode.c and device.c to walk
3400 through the function call tree and rename the registers so that they
3410 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

3417 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3419 Made bitfield a distinct type from bit so that bitfields
3420 convert as per ANSI C and bits retain their traditional
3421 boolean style behaviour. Implemented bitfield support in
3429 * src/ds390/gen.c: bit v bitfield split
3430 * src/z80/gen.c: New support for bitfields
3431 * support/regression/tests/bitfields.c: reenabled z80,
3434 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3436 Rules 246.x, 247.x relate to bitfields, the others speed up
3437 access to xdata mapped I/O devices.
3439 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
3441 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3443 Cleaned up genPackBits and genUnpackBits and added two helper
3444 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
3445 for literal assignments in genPackBits (thanks to Frieder for
3451 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3453 Fixed bug #748310 (pointer to function type mishandled when the
3454 function name is omitted). Also fixed a SIGSEGV when a function
3455 attribute (reentrant, etc) is used on a non-function or on a
3456 function but misplaced before the parameter list.
3458 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
3460 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

3483 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3485 Made the constant following the "interrupt" keyword optional. If
3486 omitted, the function will not automatically be given an entry
3487 in the interrupt vector table (similar to #pragma NOIV, but
3488 less syntacticly kludgy). The interrupt number is also now
3489 range checked. Also fixed a bug in the high order bit example

3503 * src/SDCCicode.c (operandOperation): rewritten some ops
3504 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
3505 * src/SDCCsymt.c (computeType): literals are handled the same way as any
3507 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
3508 be re-activated by defining REDUCE_LITERALS)
3509 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
3510 unsigned, but are signed by default
3511 * src/SDCCval.c (constVal): rearranged
3512 * src/SDCCval.c (valMod): preliminary fix
3513 * src/SDCCval.c (valCastLiteral): use TYPE_* types

4016 added --disable-pic16-port
4017 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
4018 * src/SDCCmain.c: linkOptions is changed to set *,
4019 added if/endif conditional macros to remove options help
4020 messages from optionsTable when a port is not configured, added
4021 support for the PIc16 port in the ports table, when executing
4022 the compiler with no port specified on command line, a default
4023 port is selected with the new macro DEFAULT_PORT which is
4024 defined in port.h, in setDefaultOptions() linkOptions is removed
4025 from initialization assignment, since now it is a set,
4026 parseCmdLine uses setParseWithComma for linkOptions, in
4027 linkEdit() linkOptions are accessed with new function indexSet()
4028 which returns the i'th item of a set variable. See SDCCset.c, in
4029 linkEdit() when calling buildCmdLine(), added linkOptions as
4030 last argument. Now users can pass arguments to gplink via the
4031 -Wl option, main() uses pic16glue() to glue up pic16 programs

4043 * src/pic16/glue.c: commented out some error producing lines
4044 * src/pic16/main.c: __config directives are commented out to stop
4045 gpasm complaining and test the linkage with gplink, _linkCmd and
4046 _asmCmd changed to be more gplink and gpasm friendly
4047 * src/pic16/peeph.def: peep rule 3 is commented out, since it
4048 produced an error when parsed, peep rule 12 is added to utilize
4049 movff, but it is commented out since the pCode does not support
4050 yet a command with 2 address arguments
4052 2003-05-18 <johan AT balder>
4054 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

4079 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
4081 2003-05-11 Borut Razem <borut.razem AT siol.net>
4083 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
4084 the path of bin directory, so that PATH is the only env. variable, which has to be set
4085 in case of standard installation.

5115 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5117 * in \sdcc\as\mcs51\ changed these files in order to create an
5118 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
5119 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
5120 following files to include the previous two files: aslink.dsp,
5121 Makefile.aslink, Makefile.bcc, and Makefile.in.
5123 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
5124 .adb instead of .cdb
5126 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5128 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
5129 value from option --iram-size.
5131 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5133 * \sdcc\as\mcs51\lklist.c: added boundary check before using
5136 2002-09-18 <wiml AT hhhh.org>
5138 * SDCClrange.h: exposed setFromRange() and setToRange()
5139 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
5140 packRegsForAccUse() (bug 542397)
5141 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
5142 multiple times and emitting the fetch operations more than once
5143 added aopGetUsesAcc() function to allow binary operators to
5144 fetch their operands in the correct order; made genMinus() emit
5145 compact code for X = LITERAL - Y
5147 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5148 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
5149 sprintf() in line 1267.
5151 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5152 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
5155 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5156 Changes to aslink (All the changes are marked with 'JCF'):
5158 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
5161 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
5162 area BSEG. Also moves, if possible, the DATA area down into the internal
5163 ram so more space is available.
5165 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
5168 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
5169 not bytes. Function summary() which creates a memory usage summary
5170 file with extension .mem. Reports of overlaping stack and small stack
5171 size. If the space for the stack is less than 16 bytes aslink trows a
5174 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
5175 the 8051. Option 'y' for memory summary output file.
5177 Changes to sdcc (All the changes are marked with 'JCF'):
5179 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
5181 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
5182 overlaying area for it (uses RegBankUsed[4]).
5184 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
5185 bank zero as used by default. By default aslink locates the stack
5186 (equivalent to --stack-after-data). Pass option 'y' to aslink for
5187 the creation of the .mem file. Delegates the allocation of data area
5188 to aslink (it is not longer 0x30 by default). If --stack-loc passes
5189 the begining of the stack area to aslink.
5191 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
5192 glue() in SDCCglue.c creates an area for it.
5194 2002-09-03 Borut Razem <borut.razem AT siol.net>
5195 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
5196 sdcc/src/pic/glue.c:
5197 introduced atexit() handler for teporay files removal in case of
5198 errors, assertions, ...
5200 2002-08-29 Borut Razem <borut.razem AT siol.net>
5201 * sdcc/support/cpp2/auto-host_vc_in.h:
5202 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
5203 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
5204 Maybe there is a similar problem with BORLANDC? It should be checked!
5206 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
5207 corrected improper use of assert: the assignment to clr variable was done inside the assert.
5208 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
5209 was not executed, and the compiler (cl) launched a warning:
5210 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
5212 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
5213 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
5215 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>

5222 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
5223 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
5224 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
5225 - added Release configuration in VS projects
5226 - review of compiler an linker options
5227 - VC .exe files are generated in bin_vc directory, not to interfere
5228 with binaries generated from other projects (cygwin, mingw, bcc ...)
5230 * sdcc/src/yacc.dsp: added
5232 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
5233 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
5234 and insert the version number definitions from .version
5236 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
5238 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
5239 added - genarate auto-host.h using auto-host_vc_in.h as template
5242 removed from CVS, generated automatically
5244 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
5245 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
5247 2002-08-11 Borut Razem <borut.razem AT siol.net>
5248 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
5250 2002-08-10 Borut Razem <borut.razem AT siol.net>
5251 * src/SDCCmain.c (main):
5252 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
5253 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
5254 The consequence was that some temporary files were not removed.
5257 unification of code in functions tempfilename() and tempfile():
5258 function tempnam() is defined in Visual Studio 6.0 and .NET
5260 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
5262 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5263 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
5264 - removed compiler command line option /WX: Treats all warnings as errors
5265 - update a list of source files, included into the project
5267 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5268 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
5269 changed project type to Generic Project so that can be correcly converted to VS.NET project
5271 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
5273 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
5275 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
5277 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
5278 added return 0 statements after assert() to make compiler happy
5280 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
5281 added newline in the def file to keep MSC compiler satisfied
5283 * sdcc/src/z80/gen.c:
5284 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
5285 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
5286 - solved MSC error in function aopDump()
5288 * sdcc_vc.h: define PREFIX as "\\sdcc"
5290 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

5339 Added -p option. Allows port dependent processor to be specified.
5342 Initialized the new field char *Processor field to NULL in all ports
5345 Compiler generated registers for interrupt context saving
5346 were not getting allocated.
5348 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
5351 Fixed left shift. Will promote the left side of a left shift
5352 if a) left shifting more than size of operand or b) when assigned
5353 to something size > size of left side
5355 2002-03-14 Scott Dattalo <scott AT dattalo.com>

5463 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
5465 * sdcc/src/SDCCloop.c:
5466 Previous fix was not good. basic blocks that have "break" or "return" are
5467 not really partof a loop , but live ranges used in these blocks should
5468 be live thru the entire loop, so set partOfLoop but don't add them to
5471 2002-02-21 <johan AT FRIJA>
5473 * src/SDCCcse.c: fixed bug #514308
5475 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
