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

1855 * src/pic/ralloc.h: applied patch from Slade Rich;
1856 added support for multiple code pages and multiple RAM banks on the
1857 PIC 14 port. The ASM files now no longer simply assume all the
1858 code / RAM are in the same page / bank. This means the linker can
1859 safely allocate code/RAM of separate ASM files to different pages/banks.
1860 * doc/sdccman.lyx: added Slade's tips
1861 * src/mcs51/peeph.def: fixed bug #880768

1903 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
1905 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
1906 loaded with the linker search paths (-L arguments) and the libraries
1907 to be linked with the current source (-l arguments). Changes
1908 currently will affect only the pic16 port.
1909 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
1910 include path the port specific paths and port specific libraries,
1911 * gplink command now contains the $3 argument,
1912 * src/pic16/device.h,
1913 * src/pic16/device.c,: structure PIC_device is made public and
1914 renamed to PIC16_device, the same for variable Pics which is renamed

1929 Documenting changes from previous commits.
1930 * configure.in (version 1.56),
1931 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
1932 when generating output files to configure the pic16 library,
1933 but now I've commented it out, since gputils aren't installed in the
1934 SF compile farm, so library won't compile
1936 * device/lib/Makefile.in (version 1.56): initially I've added in
1937 target 'all' the prerequestive 'model-pic16' so it compiled the
1938 pic16 library, but now I've commented it out for the same reasons
1940 * added targets 'model-pic16' and 'objects-pic16' to compile the
1942 * added target 'port-specific-objects-pic16' to handle the
1943 generated libraries and copy them into the build/ directory
1944 * added target 'clean-intermediate-pic16' to clean intermediate
1945 files into pic16 directory
1946 * in target 'installdirs' added line to create directory pic16 in
1947 the installation path

1950 added lines to copy all header files to installation path,
1951 * in target 'installdirs' added line create directory for pic16
1952 headers in the installation path

1967 * src/z80/main.c (_parseOptions): fixed the portmode= command line
1968 option so that it actually works. Made it specific to the z80, since
1969 the gbz80 doesn't have these kinds of I/O ports.
1971 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1973 * device/include/z180.h,

2000 data are now emitted in sorted order to reduce section naming,
2001 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
2002 weren't marked as being in the access bank,
2004 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
2006 Added portion of GNU PIC Library under the directory
2007 device/include/pic16 and device/lib/pic16. These files
2008 contain the declarations of SFRs for the PIC18Fxx2 devices.

2039 all over. Telling LaTeX to be less strict with word spacing
2040 to better keep the right margin. Changed some notes about
2041 maintainance of the ports in section 3.2.1 - is it OK like this?
2043 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

2083 * src/pic16/peeph.def: all peepholes with movff are commented out,
2084 because there is a problem in the pcode peep optimizer,
2085 * src/pic16/ralloc.c: the register allocator can now reuse local

2235 * src/SDCCast.c (decorateType): fixed bug #870781
2237 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
2239 PIC16 port related changes:
2240 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
2241 added variable stackPos,
2243 * gen.c: genCall, assignResultValue: added support for
2244 pushing/retrieving function parameters to/from stack,
2245 genFunction,genEndFunction: setup stack frame for the
2247 genAddrOf: will be changed according to bug 863624
2249 * added files genutils.c and genutils.h which contain gen*
2250 debugged and optimised functions extracted from gen.c
2252 * glue.c: added variable 'externs' which holds extern symbols,
2253 pic16emitRegularMap: is modified to properly handle relocatable
2254 symbols under the new scheme,
2255 pic16createInterruptVect: is modified
2256 pic16printPublics: is modified to emit 'global' assembler directives,
2257 added pic16_printExterns to print extern symbols,
2258 pic16glue: initializes stack/frame pointer in the beginning of
2259 the assembly output. Temporary hack, will be corrected later,
2260 because gplink yet does not support stack and SDCC does not
2261 yet support a type of crt0.o object to create the final binary.
2263 * Removed many lines that contain 8051 legacy code.
2264 * The code is finally placed under a 'code' directive.
2265 * Added port specific options.
2267 * _process_pragma: simplified since now we do not need *special*
2268 include file to define SFR registers. But a separate header
2269 will be needed. This will be developed later.
2270 * _pic16_parseOptions: added, parses port specific options:
2271 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
2272 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
2273 --preplace-udata-with=
2275 * _pic16_setDefaultOptions: modified to initialize section names,
2276 but hack is temporarly out of order since it needs improvement.
2277 * _pic16_genAssemblerPreamble: configuration words are emitted by
2278 their address instead of their name. This part is incomplete and
2279 supports only the 18Fxx2 devices. Other devices will emit an error
2280 during assembly since they do not contain the same set of config
2282 * _pic16_genIVT: is modified,
2284 * pcode.c: added definitions for some hardware registers that are needed
2286 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
2287 All PCI entries are updated. Now LFSR is supported.
2288 * Removed pic16_pciTRIS is mentioned by mdubuc in source
2289 * added pic16_newpCodeOpLit2 to support instructions with
2290 two literal arguments
2291 * pic16_pCode2str: corrected code that emits assembler instructions
2292 with two literal operands and those that have an access bit modifier
2293 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
2294 this fixes a bug which caused some labels to be lost, when an
2295 assembler directive was added, i.e. banksel,
2296 * pic16_FixRegisterBanking: improved logic that causes the insertion
2298 * InlineFunction: functions that are called once, are not any more
2299 inlined. This can be a port option in the future,
2301 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
2303 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
2304 hold the corresponding uninitialized symbols,
2305 * pic16_allocProcessorRegister: registers have explicit marked the
2307 * pic16_allocInternalRegister: registers are explicit marked as
2309 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
2310 processing list, so bit registers were lost,
2313 * ralloc.h: added field 'accessBank' and original symbol operand
2314 in register definition,
2315 * removed the field isMapped from register definition,
2317 ** Several functions have been removed from various sources:
2318 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,

2327 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
2329 * support/scripts/inc2h.pl: changed definition of BIT_AT
2330 to emit 'sbit at' instead of 'bit at'. This was a request.
2332 PIC16 port related preliminary changes:
2333 * gen.c: prefixed function popRegFromString with
2334 pic16_ and all references to it corrected
2335 * pcode.c: all pic16_pc_* hardware registers prefixed
2336 with underscore (_),
2337 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
2338 * ralloc.c: newReg(): when register is REG_SFR then
2339 set address to rIdx,
2340 pic16_allocProcessorRegister(): marks register wasUsed=0
2341 pic16_writeUsedRegs(): added a call to assign processor
2342 registers via pic16_assignFixedRegisters
2344 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2346 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
2347 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
2348 variables in unused register banks. Also the SSEG is placed
2349 wherever there is enough space for it, and IDATA can be anywhere
2350 in internal RAM. For now compile using -Wl-Y[stack_size].
2351 The mem file is different for this option as well, since it
2352 makes no sense of talking about DSEG lenght.
2354 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
2356 * src/SDCClrange.c: fixed bug 869095 that caused segfault

2603 it breaks with bitfields, extern declarations, and gcse analysis.
2604 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
2605 could be assigned through a pointer, so don't complain.

3349 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
3350 iCode properly now. Use getSize instead of nRegs since a & b
3351 aren't part of the nRegs tally.
3353 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
3355 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

3361 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
3362 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
3363 fetching of the pointer
3364 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
3365 copied from genNearPointerSet()
3366 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
3367 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
3368 If they pop r0/r1 they must be called in the opposite order than aopOp().
3369 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
3370 (resp. --stack-auto), prepared for --xstack

3381 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
3383 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3384 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
3385 type for bits was changed. It resulted in bit variables becoming
3386 global, which is not permitted in PIC 14 assembly output.
3388 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3390 * doc/sdccman.lyx: various additions and updates. Rearranged sections

3403 A few small changes that speed up the peephole optimizer.
3407 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3409 Try to make the peephole optimizer smarter by maintaining
3410 an association between the assembly source code and the
3411 iCodes that originated them. Put this information to use
3412 with a new peephole rule condition "notVolatile" so that
3413 the rules can be aggressive yet still safe.
3418 * src/mcs51/peeph.def
3420 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3424 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
3425 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
3426 if the left or right operand symbols have the accuse flag set.
3428 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3430 Changed the type of the result of the ! (NOT) operator to char;
3431 previously it returned the same type as the source. This allows
3432 us to eliminate all the genFloatNot functions (all of its target
3433 implementations were very buggy) since !float can use the same
3436 * src/SDCCicode.c (ast2iCode): ! returns char

3438 * src/ds390/gen.c (genNot, genNotFloat),
3439 * src/z80/gen.c (genNot, genNotFloat),
3440 * src/pic/gen.c (genNot, genNotFloat),

3443 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
3445 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3446 1. Interrupt would not compile properly. Ensure PCLATH register is saved
3447 during interrupts. Ensure WSAVE is located at a shared bank address.
3448 2. Fixed page selection in some places
3449 3. Fixed BTFSS/C to where necessary use registers directly and not simply
3450 the registers name strings.
3451 4. Fixed "signed / unsigned compare" compiler warnings.
3452 5. The PIC port manages its own allocation of the general purpose
3453 registers, but makes no attempt to reuse them. As a result when
3454 compiling it soon runs out of general purpose registers. Some
3455 additional code was added to the files pcode.c and device.c to walk
3456 through the function call tree and rename the registers so that they
3466 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
3467 genPlus() & genMinus() when the result is the same as left or right

3473 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3475 Made bitfield a distinct type from bit so that bitfields
3476 convert as per ANSI C and bits retain their traditional
3477 boolean style behaviour. Implemented bitfield support in
3485 * src/ds390/gen.c: bit v bitfield split
3486 * src/z80/gen.c: New support for bitfields
3487 * support/regression/tests/bitfields.c: reenabled z80,
3490 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3492 Rules 246.x, 247.x relate to bitfields, the others speed up
3493 access to xdata mapped I/O devices.
3495 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
3497 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3499 Cleaned up genPackBits and genUnpackBits and added two helper
3500 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
3501 for literal assignments in genPackBits (thanks to Frieder for
3507 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3509 Fixed bug #748310 (pointer to function type mishandled when the
3510 function name is omitted). Also fixed a SIGSEGV when a function
3511 attribute (reentrant, etc) is used on a non-function or on a
3512 function but misplaced before the parameter list.
3514 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
3516 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

3539 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3541 Made the constant following the "interrupt" keyword optional. If
3542 omitted, the function will not automatically be given an entry
3543 in the interrupt vector table (similar to #pragma NOIV, but
3544 less syntacticly kludgy). The interrupt number is also now
3545 range checked. Also fixed a bug in the high order bit example
3552 * support/Util/SDCCerr.c
3553 * support/Util/SDCCerr.h
3556 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

3559 * src/SDCCicode.c (operandOperation): rewritten some ops
3560 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
3561 * src/SDCCsymt.c (computeType): literals are handled the same way as any
3563 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
3564 be re-activated by defining REDUCE_LITERALS)
3565 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
3566 unsigned, but are signed by default
3567 * src/SDCCval.c (constVal): rearranged
3568 * src/SDCCval.c (valMod): preliminary fix
3569 * src/SDCCval.c (valCastLiteral): use TYPE_* types

4024 Using pdflatex this will give you a hyperlinked pdf file with
4025 bookmarks. (prepend '%' before /usepackage if this breaks something)

4072 added --disable-pic16-port
4073 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
4074 * src/SDCCmain.c: linkOptions is changed to set *,
4075 added if/endif conditional macros to remove options help
4076 messages from optionsTable when a port is not configured, added
4077 support for the PIc16 port in the ports table, when executing
4078 the compiler with no port specified on command line, a default
4079 port is selected with the new macro DEFAULT_PORT which is
4080 defined in port.h, in setDefaultOptions() linkOptions is removed
4081 from initialization assignment, since now it is a set,
4082 parseCmdLine uses setParseWithComma for linkOptions, in
4083 linkEdit() linkOptions are accessed with new function indexSet()
4084 which returns the i'th item of a set variable. See SDCCset.c, in
4085 linkEdit() when calling buildCmdLine(), added linkOptions as
4086 last argument. Now users can pass arguments to gplink via the
4087 -Wl option, main() uses pic16glue() to glue up pic16 programs

4099 * src/pic16/glue.c: commented out some error producing lines
4100 * src/pic16/main.c: __config directives are commented out to stop
4101 gpasm complaining and test the linkage with gplink, _linkCmd and
4102 _asmCmd changed to be more gplink and gpasm friendly
4103 * src/pic16/peeph.def: peep rule 3 is commented out, since it
4104 produced an error when parsed, peep rule 12 is added to utilize
4105 movff, but it is commented out since the pCode does not support
4106 yet a command with 2 address arguments
4108 2003-05-18 <johan AT balder>
4110 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

4137 2003-05-11 Borut Razem <borut.razem AT siol.net>
4139 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
4140 the path of bin directory, so that PATH is the only env. variable, which has to be set
4141 in case of standard installation.
4142 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

5235 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
5237 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
5238 overlaying area for it (uses RegBankUsed[4]).
5240 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
5241 bank zero as used by default. By default aslink locates the stack
5242 (equivalent to --stack-after-data). Pass option 'y' to aslink for
5243 the creation of the .mem file. Delegates the allocation of data area
5244 to aslink (it is not longer 0x30 by default). If --stack-loc passes
5245 the begining of the stack area to aslink.
5247 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
5248 glue() in SDCCglue.c creates an area for it.
5250 2002-09-03 Borut Razem <borut.razem AT siol.net>
5251 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
5252 sdcc/src/pic/glue.c:
5253 introduced atexit() handler for teporay files removal in case of
5254 errors, assertions, ...
5256 2002-08-29 Borut Razem <borut.razem AT siol.net>
5257 * sdcc/support/cpp2/auto-host_vc_in.h:
5258 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
5259 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
5260 Maybe there is a similar problem with BORLANDC? It should be checked!
5262 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
5263 corrected improper use of assert: the assignment to clr variable was done inside the assert.
5264 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
5265 was not executed, and the compiler (cl) launched a warning:
5266 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
5268 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
5269 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
5271 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
5272 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
5274 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5275 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
5276 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
5277 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5278 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
5279 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
5280 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
5281 - added Release configuration in VS projects
5282 - review of compiler an linker options
5283 - VC .exe files are generated in bin_vc directory, not to interfere
5284 with binaries generated from other projects (cygwin, mingw, bcc ...)
5286 * sdcc/src/yacc.dsp: added
5288 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
5289 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
5290 and insert the version number definitions from .version
5292 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
5294 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
5295 added - genarate auto-host.h using auto-host_vc_in.h as template
5298 removed from CVS, generated automatically
5300 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
5301 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
5303 2002-08-11 Borut Razem <borut.razem AT siol.net>
5304 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
5306 2002-08-10 Borut Razem <borut.razem AT siol.net>
5307 * src/SDCCmain.c (main):
5308 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
5309 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
5310 The consequence was that some temporary files were not removed.
5313 unification of code in functions tempfilename() and tempfile():
5314 function tempnam() is defined in Visual Studio 6.0 and .NET
5316 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
5318 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5319 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
5320 - removed compiler command line option /WX: Treats all warnings as errors
5321 - update a list of source files, included into the project
5323 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5324 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
5325 changed project type to Generic Project so that can be correcly converted to VS.NET project
5327 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
5329 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
5331 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
5333 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
5334 added return 0 statements after assert() to make compiler happy
5336 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
5337 added newline in the def file to keep MSC compiler satisfied
5339 * sdcc/src/z80/gen.c:
5340 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
5341 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
5342 - solved MSC error in function aopDump()
5344 * sdcc_vc.h: define PREFIX as "\\sdcc"
5346 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
5347 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

5395 Added -p option. Allows port dependent processor to be specified.
5398 Initialized the new field char *Processor field to NULL in all ports
5401 Compiler generated registers for interrupt context saving
5402 were not getting allocated.
5404 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
5407 Fixed left shift. Will promote the left side of a left shift
5408 if a) left shifting more than size of operand or b) when assigned
5409 to something size > size of left side
5411 2002-03-14 Scott Dattalo <scott AT dattalo.com>

5521 * sdcc/src/SDCCloop.c:
5522 Previous fix was not good. basic blocks that have "break" or "return" are
5523 not really partof a loop , but live ranges used in these blocks should
5524 be live thru the entire loop, so set partOfLoop but don't add them to
5527 2002-02-21 <johan AT FRIJA>
5529 * src/SDCCcse.c: fixed bug #514308
5531 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

5537 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
5539 2002-02-10 Karl Bongers <karl AT turbobit.com>
