1822 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
1823 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
1824 'char' to 'int' can be omitted, if both operands are 'unsigned char';
1825 see feature request #877103
1826 * src/SDCCval.c: updated call of decorateType()
1827 (valBitwise): fixed bug #882876
1828 (valMinus): added promotion
1829 (valLogicAndOr): result is unsigned
1830 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
1831 * src/SDCCsymt.c (computeType),
1832 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
1833 must not cause an unsigned operation
1834 * src/pic/glue (pic14emitRegularMap),
1835 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
1837 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>

1854 * src/pic/ralloc.h: applied patch from Slade Rich;
1855 added support for multiple code pages and multiple RAM banks on the
1856 PIC 14 port. The ASM files now no longer simply assume all the
1857 code / RAM are in the same page / bank. This means the linker can
1858 safely allocate code/RAM of separate ASM files to different pages/banks.
1859 * doc/sdccman.lyx: added Slade's tips
1860 * src/mcs51/peeph.def: fixed bug #880768

1902 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
1904 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
1905 loaded with the linker search paths (-L arguments) and the libraries
1906 to be linked with the current source (-l arguments). Changes
1907 currently will affect only the pic16 port.
1908 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
1909 include path the port specific paths and port specific libraries,
1910 * gplink command now contains the $3 argument,
1911 * src/pic16/device.h,
1912 * src/pic16/device.c,: structure PIC_device is made public and
1913 renamed to PIC16_device, the same for variable Pics which is renamed

1928 Documenting changes from previous commits.
1929 * configure.in (version 1.56),
1930 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
1931 when generating output files to configure the pic16 library,
1932 but now I've commented it out, since gputils aren't installed in the
1933 SF compile farm, so library won't compile
1935 * device/lib/Makefile.in (version 1.56): initially I've added in
1936 target 'all' the prerequestive 'model-pic16' so it compiled the
1937 pic16 library, but now I've commented it out for the same reasons
1939 * added targets 'model-pic16' and 'objects-pic16' to compile the
1941 * added target 'port-specific-objects-pic16' to handle the
1942 generated libraries and copy them into the build/ directory
1943 * added target 'clean-intermediate-pic16' to clean intermediate
1944 files into pic16 directory
1945 * in target 'installdirs' added line to create directory pic16 in
1946 the installation path

1949 added lines to copy all header files to installation path,
1950 * in target 'installdirs' added line create directory for pic16
1951 headers in the installation path

1966 * src/z80/main.c (_parseOptions): fixed the portmode= command line
1967 option so that it actually works. Made it specific to the z80, since
1968 the gbz80 doesn't have these kinds of I/O ports.
1970 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1972 * device/include/z180.h,

1996 via literal number. The symbol is placed in the corresponding
1997 position of the data ram
1998 * (pic16_dump_section): relocatable and absolute uninitialized
1999 data are now emitted in sorted order to reduce section naming,
2000 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
2001 weren't marked as being in the access bank,
2003 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
2005 Added portion of GNU PIC Library under the directory
2006 device/include/pic16 and device/lib/pic16. These files
2007 contain the declarations of SFRs for the PIC18Fxx2 devices.

2038 all over. Telling LaTeX to be less strict with word spacing
2039 to better keep the right margin. Changed some notes about
2040 maintainance of the ports in section 3.2.1 - is it OK like this?
2042 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

2082 * src/pic16/peeph.def: all peepholes with movff are commented out,
2083 because there is a problem in the pcode peep optimizer,
2084 * src/pic16/ralloc.c: the register allocator can now reuse local

2223 Bug reported from Jesus Calvino-Fraga
2225 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
2227 * sdcc.spec: updated
2228 * device/include/Makefile.in: don't install CVS directories

2231 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
2232 * src/mcs51/gen.c (genRightShift): fixed bug #870788
2233 * src/ds390/gen.c (genRightShift): fixed bug #870788
2234 * src/SDCCast.c (decorateType): fixed bug #870781
2236 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
2238 PIC16 port related changes:
2239 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
2240 added variable stackPos,
2242 * gen.c: genCall, assignResultValue: added support for
2243 pushing/retrieving function parameters to/from stack,
2244 genFunction,genEndFunction: setup stack frame for the
2246 genAddrOf: will be changed according to bug 863624
2248 * added files genutils.c and genutils.h which contain gen*
2249 debugged and optimised functions extracted from gen.c
2251 * glue.c: added variable 'externs' which holds extern symbols,
2252 pic16emitRegularMap: is modified to properly handle relocatable
2253 symbols under the new scheme,
2254 pic16createInterruptVect: is modified
2255 pic16printPublics: is modified to emit 'global' assembler directives,
2256 added pic16_printExterns to print extern symbols,
2257 pic16glue: initializes stack/frame pointer in the beginning of
2258 the assembly output. Temporary hack, will be corrected later,
2259 because gplink yet does not support stack and SDCC does not
2260 yet support a type of crt0.o object to create the final binary.
2262 * Removed many lines that contain 8051 legacy code.
2263 * The code is finally placed under a 'code' directive.
2264 * Added port specific options.
2266 * _process_pragma: simplified since now we do not need *special*
2267 include file to define SFR registers. But a separate header
2268 will be needed. This will be developed later.
2269 * _pic16_parseOptions: added, parses port specific options:
2270 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
2271 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
2272 --preplace-udata-with=
2274 * _pic16_setDefaultOptions: modified to initialize section names,
2275 but hack is temporarly out of order since it needs improvement.
2276 * _pic16_genAssemblerPreamble: configuration words are emitted by
2277 their address instead of their name. This part is incomplete and
2278 supports only the 18Fxx2 devices. Other devices will emit an error
2279 during assembly since they do not contain the same set of config
2281 * _pic16_genIVT: is modified,
2283 * pcode.c: added definitions for some hardware registers that are needed
2285 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
2286 All PCI entries are updated. Now LFSR is supported.
2287 * Removed pic16_pciTRIS is mentioned by mdubuc in source
2288 * added pic16_newpCodeOpLit2 to support instructions with
2289 two literal arguments
2290 * pic16_pCode2str: corrected code that emits assembler instructions
2291 with two literal operands and those that have an access bit modifier
2292 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
2293 this fixes a bug which caused some labels to be lost, when an
2294 assembler directive was added, i.e. banksel,
2295 * pic16_FixRegisterBanking: improved logic that causes the insertion
2297 * InlineFunction: functions that are called once, are not any more
2298 inlined. This can be a port option in the future,
2300 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
2302 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
2303 hold the corresponding uninitialized symbols,
2304 * pic16_allocProcessorRegister: registers have explicit marked the
2306 * pic16_allocInternalRegister: registers are explicit marked as
2308 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
2309 processing list, so bit registers were lost,
2312 * ralloc.h: added field 'accessBank' and original symbol operand
2313 in register definition,
2314 * removed the field isMapped from register definition,
2316 ** Several functions have been removed from various sources:

2326 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
2328 * support/scripts/inc2h.pl: changed definition of BIT_AT
2329 to emit 'sbit at' instead of 'bit at'. This was a request.
2331 PIC16 port related preliminary changes:
2332 * gen.c: prefixed function popRegFromString with
2333 pic16_ and all references to it corrected
2334 * pcode.c: all pic16_pc_* hardware registers prefixed
2335 with underscore (_),
2336 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
2337 * ralloc.c: newReg(): when register is REG_SFR then
2338 set address to rIdx,
2339 pic16_allocProcessorRegister(): marks register wasUsed=0
2340 pic16_writeUsedRegs(): added a call to assign processor
2341 registers via pic16_assignFixedRegisters
2343 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2345 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
2346 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
2347 variables in unused register banks. Also the SSEG is placed
2348 wherever there is enough space for it, and IDATA can be anywhere
2349 in internal RAM. For now compile using -Wl-Y[stack_size].
2350 The mem file is different for this option as well, since it
2351 makes no sense of talking about DSEG lenght.
2353 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
2355 * src/SDCClrange.c: fixed bug 869095 that caused segfault

2602 it breaks with bitfields, extern declarations, and gcse analysis.
2603 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
2604 could be assigned through a pointer, so don't complain.

3348 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
3349 iCode properly now. Use getSize instead of nRegs since a & b
3350 aren't part of the nRegs tally.
3352 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
3354 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

3361 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
3362 fetching of the pointer
3363 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
3364 copied from genNearPointerSet()
3365 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
3366 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
3367 If they pop r0/r1 they must be called in the opposite order than aopOp().
3368 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
3369 (resp. --stack-auto), prepared for --xstack

3380 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
3382 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3383 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
3384 type for bits was changed. It resulted in bit variables becoming
3385 global, which is not permitted in PIC 14 assembly output.
3387 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3389 * doc/sdccman.lyx: various additions and updates. Rearranged sections
3391 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3393 Z80 and MCS51 linkers complaint if a public symbol is defined

3402 A few small changes that speed up the peephole optimizer.
3406 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3408 Try to make the peephole optimizer smarter by maintaining
3409 an association between the assembly source code and the
3410 iCodes that originated them. Put this information to use
3411 with a new peephole rule condition "notVolatile" so that
3412 the rules can be aggressive yet still safe.
3417 * src/mcs51/peeph.def
3419 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3423 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
3424 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
3425 if the left or right operand symbols have the accuse flag set.
3427 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3429 Changed the type of the result of the ! (NOT) operator to char;
3430 previously it returned the same type as the source. This allows
3431 us to eliminate all the genFloatNot functions (all of its target
3432 implementations were very buggy) since !float can use the same
3435 * src/SDCCicode.c (ast2iCode): ! returns char

3437 * src/ds390/gen.c (genNot, genNotFloat),
3438 * src/z80/gen.c (genNot, genNotFloat),
3439 * src/pic/gen.c (genNot, genNotFloat),
3440 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
3442 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
3444 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3445 1. Interrupt would not compile properly. Ensure PCLATH register is saved
3446 during interrupts. Ensure WSAVE is located at a shared bank address.
3447 2. Fixed page selection in some places
3448 3. Fixed BTFSS/C to where necessary use registers directly and not simply
3449 the registers name strings.
3450 4. Fixed "signed / unsigned compare" compiler warnings.
3451 5. The PIC port manages its own allocation of the general purpose
3452 registers, but makes no attempt to reuse them. As a result when
3453 compiling it soon runs out of general purpose registers. Some
3454 additional code was added to the files pcode.c and device.c to walk
3455 through the function call tree and rename the registers so that they
3465 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
3466 genPlus() & genMinus() when the result is the same as left or right

3472 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3474 Made bitfield a distinct type from bit so that bitfields
3475 convert as per ANSI C and bits retain their traditional
3476 boolean style behaviour. Implemented bitfield support in
3484 * src/ds390/gen.c: bit v bitfield split
3485 * src/z80/gen.c: New support for bitfields
3486 * support/regression/tests/bitfields.c: reenabled z80,
3489 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3491 Rules 246.x, 247.x relate to bitfields, the others speed up
3492 access to xdata mapped I/O devices.
3494 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
3496 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3498 Cleaned up genPackBits and genUnpackBits and added two helper
3499 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
3500 for literal assignments in genPackBits (thanks to Frieder for
3506 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3508 Fixed bug #748310 (pointer to function type mishandled when the
3509 function name is omitted). Also fixed a SIGSEGV when a function
3510 attribute (reentrant, etc) is used on a non-function or on a
3511 function but misplaced before the parameter list.
3513 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
3515 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

3538 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3540 Made the constant following the "interrupt" keyword optional. If
3541 omitted, the function will not automatically be given an entry
3542 in the interrupt vector table (similar to #pragma NOIV, but
3543 less syntacticly kludgy). The interrupt number is also now
3544 range checked. Also fixed a bug in the high order bit example

3558 * src/SDCCicode.c (operandOperation): rewritten some ops
3559 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
3560 * src/SDCCsymt.c (computeType): literals are handled the same way as any
3562 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
3563 be re-activated by defining REDUCE_LITERALS)
3564 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
3565 unsigned, but are signed by default
3566 * src/SDCCval.c (constVal): rearranged
3567 * src/SDCCval.c (valMod): preliminary fix
3568 * src/SDCCval.c (valCastLiteral): use TYPE_* types

4023 Using pdflatex this will give you a hyperlinked pdf file with
4024 bookmarks. (prepend '%' before /usepackage if this breaks something)

4062 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
4064 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
4065 it can be defined with CFLAGS when running configure
4066 * src/SDCCmain.c: fixed compiling + linking with object files
4068 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

4071 added --disable-pic16-port
4072 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
4073 * src/SDCCmain.c: linkOptions is changed to set *,
4074 added if/endif conditional macros to remove options help
4075 messages from optionsTable when a port is not configured, added
4076 support for the PIc16 port in the ports table, when executing
4077 the compiler with no port specified on command line, a default
4078 port is selected with the new macro DEFAULT_PORT which is
4079 defined in port.h, in setDefaultOptions() linkOptions is removed
4080 from initialization assignment, since now it is a set,
4081 parseCmdLine uses setParseWithComma for linkOptions, in
4082 linkEdit() linkOptions are accessed with new function indexSet()
4083 which returns the i'th item of a set variable. See SDCCset.c, in
4084 linkEdit() when calling buildCmdLine(), added linkOptions as
4085 last argument. Now users can pass arguments to gplink via the
4086 -Wl option, main() uses pic16glue() to glue up pic16 programs

4098 * src/pic16/glue.c: commented out some error producing lines
4099 * src/pic16/main.c: __config directives are commented out to stop
4100 gpasm complaining and test the linkage with gplink, _linkCmd and
4101 _asmCmd changed to be more gplink and gpasm friendly
4102 * src/pic16/peeph.def: peep rule 3 is commented out, since it
4103 produced an error when parsed, peep rule 12 is added to utilize
4104 movff, but it is commented out since the pCode does not support
4105 yet a command with 2 address arguments
4107 2003-05-18 <johan AT balder>
4109 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

4136 2003-05-11 Borut Razem <borut.razem AT siol.net>
4138 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
4139 the path of bin directory, so that PATH is the only env. variable, which has to be set
4140 in case of standard installation.
4141 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

5234 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
5236 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
5237 overlaying area for it (uses RegBankUsed[4]).
5239 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
5240 bank zero as used by default. By default aslink locates the stack
5241 (equivalent to --stack-after-data). Pass option 'y' to aslink for
5242 the creation of the .mem file. Delegates the allocation of data area
5243 to aslink (it is not longer 0x30 by default). If --stack-loc passes
5244 the begining of the stack area to aslink.
5246 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
5247 glue() in SDCCglue.c creates an area for it.
5249 2002-09-03 Borut Razem <borut.razem AT siol.net>
5250 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
5251 sdcc/src/pic/glue.c:
5252 introduced atexit() handler for teporay files removal in case of
5253 errors, assertions, ...
5255 2002-08-29 Borut Razem <borut.razem AT siol.net>
5256 * sdcc/support/cpp2/auto-host_vc_in.h:
5257 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
5258 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
5259 Maybe there is a similar problem with BORLANDC? It should be checked!
5261 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
5262 corrected improper use of assert: the assignment to clr variable was done inside the assert.
5263 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
5264 was not executed, and the compiler (cl) launched a warning:
5265 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
5267 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
5268 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
5270 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
5271 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
5273 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5274 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
5275 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
5276 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5277 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
5278 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
5279 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
5280 - added Release configuration in VS projects
5281 - review of compiler an linker options
5282 - VC .exe files are generated in bin_vc directory, not to interfere
5283 with binaries generated from other projects (cygwin, mingw, bcc ...)
5285 * sdcc/src/yacc.dsp: added
5287 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
5288 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
5289 and insert the version number definitions from .version
5291 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
5293 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
5294 added - genarate auto-host.h using auto-host_vc_in.h as template
5297 removed from CVS, generated automatically
5299 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
5300 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
5302 2002-08-11 Borut Razem <borut.razem AT siol.net>
5303 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
5305 2002-08-10 Borut Razem <borut.razem AT siol.net>
5306 * src/SDCCmain.c (main):
5307 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
5308 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
5309 The consequence was that some temporary files were not removed.
5312 unification of code in functions tempfilename() and tempfile():
5313 function tempnam() is defined in Visual Studio 6.0 and .NET
5315 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
5317 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5318 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
5319 - removed compiler command line option /WX: Treats all warnings as errors
5320 - update a list of source files, included into the project
5322 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5323 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
5324 changed project type to Generic Project so that can be correcly converted to VS.NET project
5326 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
5328 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
5330 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
5332 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
5333 added return 0 statements after assert() to make compiler happy
5335 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
5336 added newline in the def file to keep MSC compiler satisfied
5338 * sdcc/src/z80/gen.c:
5339 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
5340 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
5341 - solved MSC error in function aopDump()
5343 * sdcc_vc.h: define PREFIX as "\\sdcc"
5345 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
5346 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

5394 Added -p option. Allows port dependent processor to be specified.
5397 Initialized the new field char *Processor field to NULL in all ports
5400 Compiler generated registers for interrupt context saving
5401 were not getting allocated.
5403 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
5406 Fixed left shift. Will promote the left side of a left shift
5407 if a) left shifting more than size of operand or b) when assigned
5408 to something size > size of left side
5410 2002-03-14 Scott Dattalo <scott AT dattalo.com>

5520 * sdcc/src/SDCCloop.c:
5521 Previous fix was not good. basic blocks that have "break" or "return" are
5522 not really partof a loop , but live ranges used in these blocks should
5523 be live thru the entire loop, so set partOfLoop but don't add them to
5526 2002-02-21 <johan AT FRIJA>
5528 * src/SDCCcse.c: fixed bug #514308
5530 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

5536 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
5538 2002-02-10 Karl Bongers <karl AT turbobit.com>
