1823 * support/regression/ports/ucz80/spec.mk (UCZ80): Made detect the
1826 * support/regression/generate-cases.py (main): Changed from inline
1829 * doc/Makefile (install): Changed to depth first to get rid of
1830 missing directory install warning.
1832 * as/Makefile (install-doc): Made work on Mac.
1834 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
1836 * src/SDCCast.c: added an additional type flow in decorateType() of
1837 opposite direction, see feature request #860006; it's enabled at runtime
1838 by setting the environment variable SDCC_NEWTYPEFLOW
1839 * src/SDCCast.h: changed prototype of decorateType()
1840 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
1841 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
1842 'char' to 'int' can be omitted, if both operands are 'unsigned char';
1843 see feature request #877103
1844 * src/SDCCval.c: updated call of decorateType()
1845 (valBitwise): fixed bug #882876
1846 (valMinus): added promotion
1847 (valLogicAndOr): result is unsigned
1848 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
1849 * src/SDCCsymt.c (computeType),
1850 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
1851 must not cause an unsigned operation

1872 * src/pic/ralloc.h: applied patch from Slade Rich;
1873 added support for multiple code pages and multiple RAM banks on the
1874 PIC 14 port. The ASM files now no longer simply assume all the
1875 code / RAM are in the same page / bank. This means the linker can
1876 safely allocate code/RAM of separate ASM files to different pages/banks.
1877 * doc/sdccman.lyx: added Slade's tips
1878 * src/mcs51/peeph.def: fixed bug #880768

1920 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
1922 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
1923 loaded with the linker search paths (-L arguments) and the libraries
1924 to be linked with the current source (-l arguments). Changes
1925 currently will affect only the pic16 port.
1926 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
1927 include path the port specific paths and port specific libraries,
1928 * gplink command now contains the $3 argument,
1929 * src/pic16/device.h,
1930 * src/pic16/device.c,: structure PIC_device is made public and
1931 renamed to PIC16_device, the same for variable Pics which is renamed

1946 Documenting changes from previous commits.
1947 * configure.in (version 1.56),
1948 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
1949 when generating output files to configure the pic16 library,
1950 but now I've commented it out, since gputils aren't installed in the
1951 SF compile farm, so library won't compile
1953 * device/lib/Makefile.in (version 1.56): initially I've added in
1954 target 'all' the prerequestive 'model-pic16' so it compiled the
1955 pic16 library, but now I've commented it out for the same reasons
1957 * added targets 'model-pic16' and 'objects-pic16' to compile the
1959 * added target 'port-specific-objects-pic16' to handle the
1960 generated libraries and copy them into the build/ directory
1961 * added target 'clean-intermediate-pic16' to clean intermediate
1962 files into pic16 directory
1963 * in target 'installdirs' added line to create directory pic16 in
1964 the installation path

1967 added lines to copy all header files to installation path,
1968 * in target 'installdirs' added line create directory for pic16
1969 headers in the installation path

1984 * src/z80/main.c (_parseOptions): fixed the portmode= command line
1985 option so that it actually works. Made it specific to the z80, since
1986 the gbz80 doesn't have these kinds of I/O ports.
1988 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1990 * device/include/z180.h,

2014 via literal number. The symbol is placed in the corresponding
2015 position of the data ram
2016 * (pic16_dump_section): relocatable and absolute uninitialized
2017 data are now emitted in sorted order to reduce section naming,
2018 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
2019 weren't marked as being in the access bank,
2021 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
2023 Added portion of GNU PIC Library under the directory
2024 device/include/pic16 and device/lib/pic16. These files
2025 contain the declarations of SFRs for the PIC18Fxx2 devices.

2056 all over. Telling LaTeX to be less strict with word spacing
2057 to better keep the right margin. Changed some notes about
2058 maintainance of the ports in section 3.2.1 - is it OK like this?
2060 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

2100 * src/pic16/peeph.def: all peepholes with movff are commented out,
2101 because there is a problem in the pcode peep optimizer,
2102 * src/pic16/ralloc.c: the register allocator can now reuse local

2243 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
2245 * sdcc.spec: updated

2254 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
2256 PIC16 port related changes:
2257 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
2258 added variable stackPos,
2260 * gen.c: genCall, assignResultValue: added support for
2261 pushing/retrieving function parameters to/from stack,
2262 genFunction,genEndFunction: setup stack frame for the
2264 genAddrOf: will be changed according to bug 863624
2266 * added files genutils.c and genutils.h which contain gen*
2267 debugged and optimised functions extracted from gen.c
2269 * glue.c: added variable 'externs' which holds extern symbols,
2270 pic16emitRegularMap: is modified to properly handle relocatable
2271 symbols under the new scheme,
2272 pic16createInterruptVect: is modified
2273 pic16printPublics: is modified to emit 'global' assembler directives,
2274 added pic16_printExterns to print extern symbols,
2275 pic16glue: initializes stack/frame pointer in the beginning of
2276 the assembly output. Temporary hack, will be corrected later,
2277 because gplink yet does not support stack and SDCC does not
2278 yet support a type of crt0.o object to create the final binary.
2280 * Removed many lines that contain 8051 legacy code.
2281 * The code is finally placed under a 'code' directive.
2282 * Added port specific options.
2284 * _process_pragma: simplified since now we do not need *special*
2285 include file to define SFR registers. But a separate header
2286 will be needed. This will be developed later.
2287 * _pic16_parseOptions: added, parses port specific options:
2288 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
2289 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
2290 --preplace-udata-with=
2292 * _pic16_setDefaultOptions: modified to initialize section names,
2293 but hack is temporarly out of order since it needs improvement.
2294 * _pic16_genAssemblerPreamble: configuration words are emitted by
2295 their address instead of their name. This part is incomplete and
2296 supports only the 18Fxx2 devices. Other devices will emit an error
2297 during assembly since they do not contain the same set of config
2299 * _pic16_genIVT: is modified,
2301 * pcode.c: added definitions for some hardware registers that are needed
2303 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
2304 All PCI entries are updated. Now LFSR is supported.
2305 * Removed pic16_pciTRIS is mentioned by mdubuc in source
2306 * added pic16_newpCodeOpLit2 to support instructions with
2307 two literal arguments
2308 * pic16_pCode2str: corrected code that emits assembler instructions
2309 with two literal operands and those that have an access bit modifier
2310 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
2311 this fixes a bug which caused some labels to be lost, when an
2312 assembler directive was added, i.e. banksel,
2313 * pic16_FixRegisterBanking: improved logic that causes the insertion
2315 * InlineFunction: functions that are called once, are not any more
2316 inlined. This can be a port option in the future,
2318 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
2320 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
2321 hold the corresponding uninitialized symbols,
2322 * pic16_allocProcessorRegister: registers have explicit marked the
2324 * pic16_allocInternalRegister: registers are explicit marked as
2326 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
2327 processing list, so bit registers were lost,
2330 * ralloc.h: added field 'accessBank' and original symbol operand
2331 in register definition,
2332 * removed the field isMapped from register definition,
2334 ** Several functions have been removed from various sources:
2335 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
2336 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
2337 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
2338 pic16_assignRelocatableRegisters
2340 ** others have been introduced:
2341 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
2342 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
2344 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
2346 * support/scripts/inc2h.pl: changed definition of BIT_AT
2347 to emit 'sbit at' instead of 'bit at'. This was a request.
2349 PIC16 port related preliminary changes:
2350 * gen.c: prefixed function popRegFromString with
2351 pic16_ and all references to it corrected
2352 * pcode.c: all pic16_pc_* hardware registers prefixed
2353 with underscore (_),
2354 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
2355 * ralloc.c: newReg(): when register is REG_SFR then
2356 set address to rIdx,
2357 pic16_allocProcessorRegister(): marks register wasUsed=0
2358 pic16_writeUsedRegs(): added a call to assign processor
2359 registers via pic16_assignFixedRegisters
2361 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2363 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
2364 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
2365 variables in unused register banks. Also the SSEG is placed
2366 wherever there is enough space for it, and IDATA can be anywhere
2367 in internal RAM. For now compile using -Wl-Y[stack_size].
2368 The mem file is different for this option as well, since it
2369 makes no sense of talking about DSEG lenght.
2371 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
2373 * src/SDCClrange.c: fixed bug 869095 that caused segfault

2618 * src/SDCCast.c (decorateType): disabled a transformation I added in
2619 revision 1.188 (access to fields of a structure at an absolute address);
2620 it breaks with bitfields, extern declarations, and gcse analysis.
2621 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
2622 could be assigned through a pointer, so don't complain.

3381 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
3382 copied from genNearPointerSet()
3383 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
3384 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

3398 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
3400 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3401 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
3402 type for bits was changed. It resulted in bit variables becoming
3403 global, which is not permitted in PIC 14 assembly output.
3405 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3407 * doc/sdccman.lyx: various additions and updates. Rearranged sections

3418 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3420 A few small changes that speed up the peephole optimizer.
3424 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3426 Try to make the peephole optimizer smarter by maintaining
3427 an association between the assembly source code and the
3428 iCodes that originated them. Put this information to use
3429 with a new peephole rule condition "notVolatile" so that
3430 the rules can be aggressive yet still safe.
3435 * src/mcs51/peeph.def
3437 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3441 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
3442 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
3443 if the left or right operand symbols have the accuse flag set.
3445 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3447 Changed the type of the result of the ! (NOT) operator to char;
3448 previously it returned the same type as the source. This allows
3449 us to eliminate all the genFloatNot functions (all of its target
3450 implementations were very buggy) since !float can use the same
3453 * src/SDCCicode.c (ast2iCode): ! returns char
3454 * src/mcs51/gen.c (genNot, genNotFloat),
3455 * src/ds390/gen.c (genNot, genNotFloat),
3456 * src/z80/gen.c (genNot, genNotFloat),
3457 * src/pic/gen.c (genNot, genNotFloat),
3458 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
3460 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
3462 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3463 1. Interrupt would not compile properly. Ensure PCLATH register is saved
3464 during interrupts. Ensure WSAVE is located at a shared bank address.
3465 2. Fixed page selection in some places
3466 3. Fixed BTFSS/C to where necessary use registers directly and not simply
3467 the registers name strings.
3468 4. Fixed "signed / unsigned compare" compiler warnings.
3469 5. The PIC port manages its own allocation of the general purpose
3470 registers, but makes no attempt to reuse them. As a result when
3471 compiling it soon runs out of general purpose registers. Some
3472 additional code was added to the files pcode.c and device.c to walk
3473 through the function call tree and rename the registers so that they
3483 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
3484 genPlus() & genMinus() when the result is the same as left or right

3490 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3492 Made bitfield a distinct type from bit so that bitfields
3493 convert as per ANSI C and bits retain their traditional
3494 boolean style behaviour. Implemented bitfield support in
3502 * src/ds390/gen.c: bit v bitfield split
3503 * src/z80/gen.c: New support for bitfields
3504 * support/regression/tests/bitfields.c: reenabled z80,
3507 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3509 Rules 246.x, 247.x relate to bitfields, the others speed up
3510 access to xdata mapped I/O devices.
3512 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
3514 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3516 Cleaned up genPackBits and genUnpackBits and added two helper
3517 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
3518 for literal assignments in genPackBits (thanks to Frieder for
3524 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3526 Fixed bug #748310 (pointer to function type mishandled when the
3527 function name is omitted). Also fixed a SIGSEGV when a function
3528 attribute (reentrant, etc) is used on a non-function or on a
3529 function but misplaced before the parameter list.
3531 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
3533 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

3556 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3558 Made the constant following the "interrupt" keyword optional. If
3559 omitted, the function will not automatically be given an entry
3560 in the interrupt vector table (similar to #pragma NOIV, but
3561 less syntacticly kludgy). The interrupt number is also now
3562 range checked. Also fixed a bug in the high order bit example

3576 * src/SDCCicode.c (operandOperation): rewritten some ops
3577 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
3578 * src/SDCCsymt.c (computeType): literals are handled the same way as any
3580 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
3581 be re-activated by defining REDUCE_LITERALS)
3582 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
3583 unsigned, but are signed by default
3584 * src/SDCCval.c (constVal): rearranged
3585 * src/SDCCval.c (valMod): preliminary fix
3586 * src/SDCCval.c (valCastLiteral): use TYPE_* types

4041 Using pdflatex this will give you a hyperlinked pdf file with
4042 bookmarks. (prepend '%' before /usepackage if this breaks something)

4089 added --disable-pic16-port
4090 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
4091 * src/SDCCmain.c: linkOptions is changed to set *,
4092 added if/endif conditional macros to remove options help
4093 messages from optionsTable when a port is not configured, added
4094 support for the PIc16 port in the ports table, when executing
4095 the compiler with no port specified on command line, a default
4096 port is selected with the new macro DEFAULT_PORT which is
4097 defined in port.h, in setDefaultOptions() linkOptions is removed
4098 from initialization assignment, since now it is a set,
4099 parseCmdLine uses setParseWithComma for linkOptions, in
4100 linkEdit() linkOptions are accessed with new function indexSet()
4101 which returns the i'th item of a set variable. See SDCCset.c, in
4102 linkEdit() when calling buildCmdLine(), added linkOptions as
4103 last argument. Now users can pass arguments to gplink via the
4104 -Wl option, main() uses pic16glue() to glue up pic16 programs

4116 * src/pic16/glue.c: commented out some error producing lines
4117 * src/pic16/main.c: __config directives are commented out to stop
4118 gpasm complaining and test the linkage with gplink, _linkCmd and
4119 _asmCmd changed to be more gplink and gpasm friendly
4120 * src/pic16/peeph.def: peep rule 3 is commented out, since it
4121 produced an error when parsed, peep rule 12 is added to utilize
4122 movff, but it is commented out since the pCode does not support
4123 yet a command with 2 address arguments
4125 2003-05-18 <johan AT balder>
4127 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

4154 2003-05-11 Borut Razem <borut.razem AT siol.net>
4156 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
4157 the path of bin directory, so that PATH is the only env. variable, which has to be set
4158 in case of standard installation.

5231 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
5234 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
5235 area BSEG. Also moves, if possible, the DATA area down into the internal
5236 ram so more space is available.
5238 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
5241 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
5242 not bytes. Function summary() which creates a memory usage summary
5243 file with extension .mem. Reports of overlaping stack and small stack
5244 size. If the space for the stack is less than 16 bytes aslink trows a
5247 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
5248 the 8051. Option 'y' for memory summary output file.
5250 Changes to sdcc (All the changes are marked with 'JCF'):
5252 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
5254 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
5255 overlaying area for it (uses RegBankUsed[4]).
5257 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
5258 bank zero as used by default. By default aslink locates the stack
5259 (equivalent to --stack-after-data). Pass option 'y' to aslink for
5260 the creation of the .mem file. Delegates the allocation of data area
5261 to aslink (it is not longer 0x30 by default). If --stack-loc passes
5262 the begining of the stack area to aslink.
5264 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
5265 glue() in SDCCglue.c creates an area for it.
5267 2002-09-03 Borut Razem <borut.razem AT siol.net>
5268 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
5269 sdcc/src/pic/glue.c:
5270 introduced atexit() handler for teporay files removal in case of
5271 errors, assertions, ...
5273 2002-08-29 Borut Razem <borut.razem AT siol.net>
5274 * sdcc/support/cpp2/auto-host_vc_in.h:
5275 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
5276 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
5277 Maybe there is a similar problem with BORLANDC? It should be checked!
5279 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
5280 corrected improper use of assert: the assignment to clr variable was done inside the assert.
5281 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
5282 was not executed, and the compiler (cl) launched a warning:
5283 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
5285 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
5286 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
5288 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
5289 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
5291 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5292 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
5293 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
5294 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5295 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
5296 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
5297 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
5298 - added Release configuration in VS projects
5299 - review of compiler an linker options
5300 - VC .exe files are generated in bin_vc directory, not to interfere
5301 with binaries generated from other projects (cygwin, mingw, bcc ...)
5303 * sdcc/src/yacc.dsp: added
5305 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
5306 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
5307 and insert the version number definitions from .version
5309 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
5311 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
5312 added - genarate auto-host.h using auto-host_vc_in.h as template
5315 removed from CVS, generated automatically
5317 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
5318 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
5320 2002-08-11 Borut Razem <borut.razem AT siol.net>
5321 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
5323 2002-08-10 Borut Razem <borut.razem AT siol.net>
5324 * src/SDCCmain.c (main):
5325 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
5326 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
5327 The consequence was that some temporary files were not removed.
5330 unification of code in functions tempfilename() and tempfile():
5331 function tempnam() is defined in Visual Studio 6.0 and .NET
5333 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
5335 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5336 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
5337 - removed compiler command line option /WX: Treats all warnings as errors
5338 - update a list of source files, included into the project
5340 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5341 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
5342 changed project type to Generic Project so that can be correcly converted to VS.NET project
5344 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
5346 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
5348 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
5350 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
5351 added return 0 statements after assert() to make compiler happy
5353 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
5354 added newline in the def file to keep MSC compiler satisfied
5356 * sdcc/src/z80/gen.c:
5357 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
5358 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
5359 - solved MSC error in function aopDump()
5361 * sdcc_vc.h: define PREFIX as "\\sdcc"
5363 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
5364 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

5412 Added -p option. Allows port dependent processor to be specified.
5415 Initialized the new field char *Processor field to NULL in all ports
5418 Compiler generated registers for interrupt context saving
5419 were not getting allocated.
5421 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
5424 Fixed left shift. Will promote the left side of a left shift
5425 if a) left shifting more than size of operand or b) when assigned
5426 to something size > size of left side
5428 2002-03-14 Scott Dattalo <scott AT dattalo.com>

5536 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
5538 * sdcc/src/SDCCloop.c:
5539 Previous fix was not good. basic blocks that have "break" or "return" are
5540 not really partof a loop , but live ranges used in these blocks should
5541 be live thru the entire loop, so set partOfLoop but don't add them to
5544 2002-02-21 <johan AT FRIJA>
5546 * src/SDCCcse.c: fixed bug #514308
5548 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

5554 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
5556 2002-02-10 Karl Bongers <karl AT turbobit.com>
