178 functions, ctype functions and macros and some functions of the
179 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
180 be extensively tested in the future. Standard disclaimer here.

197 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
199 * (genCast): began a fix to optimize the casting of a bit to another

3142 * src/SDCCast.h: changed prototype of decorateType()
3143 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
3144 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
3145 'char' to 'int' can be omitted, if both operands are 'unsigned char';
3146 see feature request #877103
3147 * src/SDCCval.c: updated call of decorateType()
3148 (valBitwise): fixed bug #882876
3149 (valMinus): added promotion
3150 (valLogicAndOr): result is unsigned
3151 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
3152 * src/SDCCsymt.c (computeType),
3153 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
3154 must not cause an unsigned operation
3155 * src/pic/glue (pic14emitRegularMap),
3156 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
3158 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>

3175 * src/pic/ralloc.h: applied patch from Slade Rich;
3176 added support for multiple code pages and multiple RAM banks on the
3177 PIC 14 port. The ASM files now no longer simply assume all the
3178 code / RAM are in the same page / bank. This means the linker can
3179 safely allocate code/RAM of separate ASM files to different pages/banks.
3180 * doc/sdccman.lyx: added Slade's tips
3181 * src/mcs51/peeph.def: fixed bug #880768

3193 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
3194 strtof is not part of C89 and isn't included with Mac OS X.
3196 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3198 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

3223 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3225 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3226 loaded with the linker search paths (-L arguments) and the libraries
3227 to be linked with the current source (-l arguments). Changes
3228 currently will affect only the pic16 port.
3229 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3230 include path the port specific paths and port specific libraries,
3231 * gplink command now contains the $3 argument,
3232 * src/pic16/device.h,
3233 * src/pic16/device.c,: structure PIC_device is made public and
3234 renamed to PIC16_device, the same for variable Pics which is renamed

3249 Documenting changes from previous commits.
3250 * configure.in (version 1.56),
3251 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3252 when generating output files to configure the pic16 library,
3253 but now I've commented it out, since gputils aren't installed in the
3254 SF compile farm, so library won't compile
3256 * device/lib/Makefile.in (version 1.56): initially I've added in
3257 target 'all' the prerequestive 'model-pic16' so it compiled the
3258 pic16 library, but now I've commented it out for the same reasons
3260 * added targets 'model-pic16' and 'objects-pic16' to compile the
3262 * added target 'port-specific-objects-pic16' to handle the
3263 generated libraries and copy them into the build/ directory
3264 * added target 'clean-intermediate-pic16' to clean intermediate
3265 files into pic16 directory
3266 * in target 'installdirs' added line to create directory pic16 in
3267 the installation path
3269 * device/include/Makefile.in (version 1.11): in target 'install'
3270 added lines to copy all header files to installation path,
3271 * in target 'installdirs' added line create directory for pic16
3272 headers in the installation path

3287 * src/z80/main.c (_parseOptions): fixed the portmode= command line
3288 option so that it actually works. Made it specific to the z80, since
3289 the gbz80 doesn't have these kinds of I/O ports.
3291 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3293 * device/include/z180.h,

3315 Mainly changes to support compilation of the device libraries
3316 * src/pic16/device.c: stack is allocated via symbol and not
3317 via literal number. The symbol is placed in the corresponding
3318 position of the data ram
3319 * (pic16_dump_section): relocatable and absolute uninitialized
3320 data are now emitted in sorted order to reduce section naming,
3321 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3322 weren't marked as being in the access bank,
3324 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3326 Added portion of GNU PIC Library under the directory
3327 device/include/pic16 and device/lib/pic16. These files
3328 contain the declarations of SFRs for the PIC18Fxx2 devices.
3329 The directory is initialized via configure from toplevel.
3331 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
3333 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

3359 all over. Telling LaTeX to be less strict with word spacing
3360 to better keep the right margin. Changed some notes about
3361 maintainance of the ports in section 3.2.1 - is it OK like this?
3363 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

3403 * src/pic16/peeph.def: all peepholes with movff are commented out,
3404 because there is a problem in the pcode peep optimizer,
3405 * src/pic16/ralloc.c: the register allocator can now reuse local

3557 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3559 PIC16 port related changes:
3560 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3561 added variable stackPos,
3563 * gen.c: genCall, assignResultValue: added support for
3564 pushing/retrieving function parameters to/from stack,
3565 genFunction,genEndFunction: setup stack frame for the
3567 genAddrOf: will be changed according to bug 863624
3569 * added files genutils.c and genutils.h which contain gen*
3570 debugged and optimised functions extracted from gen.c
3572 * glue.c: added variable 'externs' which holds extern symbols,
3573 pic16emitRegularMap: is modified to properly handle relocatable
3574 symbols under the new scheme,
3575 pic16createInterruptVect: is modified
3576 pic16printPublics: is modified to emit 'global' assembler directives,
3577 added pic16_printExterns to print extern symbols,
3578 pic16glue: initializes stack/frame pointer in the beginning of
3579 the assembly output. Temporary hack, will be corrected later,
3580 because gplink yet does not support stack and SDCC does not
3581 yet support a type of crt0.o object to create the final binary.
3583 * Removed many lines that contain 8051 legacy code.
3584 * The code is finally placed under a 'code' directive.
3585 * Added port specific options.
3587 * _process_pragma: simplified since now we do not need *special*
3588 include file to define SFR registers. But a separate header
3589 will be needed. This will be developed later.
3590 * _pic16_parseOptions: added, parses port specific options:
3591 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3592 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3593 --preplace-udata-with=
3595 * _pic16_setDefaultOptions: modified to initialize section names,
3596 but hack is temporarly out of order since it needs improvement.
3597 * _pic16_genAssemblerPreamble: configuration words are emitted by
3598 their address instead of their name. This part is incomplete and
3599 supports only the 18Fxx2 devices. Other devices will emit an error
3600 during assembly since they do not contain the same set of config
3602 * _pic16_genIVT: is modified,
3604 * pcode.c: added definitions for some hardware registers that are needed
3606 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3607 All PCI entries are updated. Now LFSR is supported.
3608 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3609 * added pic16_newpCodeOpLit2 to support instructions with
3610 two literal arguments
3611 * pic16_pCode2str: corrected code that emits assembler instructions
3612 with two literal operands and those that have an access bit modifier
3613 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3614 this fixes a bug which caused some labels to be lost, when an
3615 assembler directive was added, i.e. banksel,
3616 * pic16_FixRegisterBanking: improved logic that causes the insertion
3618 * InlineFunction: functions that are called once, are not any more
3619 inlined. This can be a port option in the future,
3621 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3623 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3624 hold the corresponding uninitialized symbols,
3625 * pic16_allocProcessorRegister: registers have explicit marked the
3627 * pic16_allocInternalRegister: registers are explicit marked as
3629 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3630 processing list, so bit registers were lost,
3633 * ralloc.h: added field 'accessBank' and original symbol operand
3634 in register definition,
3635 * removed the field isMapped from register definition,
3637 ** Several functions have been removed from various sources:
3638 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,

3647 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3649 * support/scripts/inc2h.pl: changed definition of BIT_AT
3650 to emit 'sbit at' instead of 'bit at'. This was a request.
3652 PIC16 port related preliminary changes:
3653 * gen.c: prefixed function popRegFromString with
3654 pic16_ and all references to it corrected
3655 * pcode.c: all pic16_pc_* hardware registers prefixed
3656 with underscore (_),
3657 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3658 * ralloc.c: newReg(): when register is REG_SFR then
3659 set address to rIdx,
3660 pic16_allocProcessorRegister(): marks register wasUsed=0
3661 pic16_writeUsedRegs(): added a call to assign processor
3662 registers via pic16_assignFixedRegisters
3664 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3666 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3667 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3668 variables in unused register banks. Also the SSEG is placed
3669 wherever there is enough space for it, and IDATA can be anywhere
3670 in internal RAM. For now compile using -Wl-Y[stack_size].
3671 The mem file is different for this option as well, since it
3672 makes no sense of talking about DSEG lenght.
3674 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3676 * src/SDCClrange.c: fixed bug 869095 that caused segfault

3923 it breaks with bitfields, extern declarations, and gcse analysis.
3924 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
3925 could be assigned through a pointer, so don't complain.

4669 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
4670 iCode properly now. Use getSize instead of nRegs since a & b
4671 aren't part of the nRegs tally.
4673 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
4675 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

4682 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
4683 fetching of the pointer
4684 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
4685 copied from genNearPointerSet()
4686 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
4687 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
4688 If they pop r0/r1 they must be called in the opposite order than aopOp().
4689 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
4690 (resp. --stack-auto), prepared for --xstack

4701 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
4703 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4704 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4705 type for bits was changed. It resulted in bit variables becoming
4706 global, which is not permitted in PIC 14 assembly output.
4708 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4710 * doc/sdccman.lyx: various additions and updates. Rearranged sections

4723 A few small changes that speed up the peephole optimizer.
4727 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4729 Try to make the peephole optimizer smarter by maintaining
4730 an association between the assembly source code and the
4731 iCodes that originated them. Put this information to use
4732 with a new peephole rule condition "notVolatile" so that
4733 the rules can be aggressive yet still safe.
4738 * src/mcs51/peeph.def
4740 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4744 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4745 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4746 if the left or right operand symbols have the accuse flag set.
4748 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4750 Changed the type of the result of the ! (NOT) operator to char;
4751 previously it returned the same type as the source. This allows
4752 us to eliminate all the genFloatNot functions (all of its target
4753 implementations were very buggy) since !float can use the same
4756 * src/SDCCicode.c (ast2iCode): ! returns char

4758 * src/ds390/gen.c (genNot, genNotFloat),
4759 * src/z80/gen.c (genNot, genNotFloat),
4760 * src/pic/gen.c (genNot, genNotFloat),

4763 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
4765 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4766 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4767 during interrupts. Ensure WSAVE is located at a shared bank address.
4768 2. Fixed page selection in some places
4769 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4770 the registers name strings.
4771 4. Fixed "signed / unsigned compare" compiler warnings.
4772 5. The PIC port manages its own allocation of the general purpose
4773 registers, but makes no attempt to reuse them. As a result when
4774 compiling it soon runs out of general purpose registers. Some
4775 additional code was added to the files pcode.c and device.c to walk
4776 through the function call tree and rename the registers so that they
4786 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
4787 genPlus() & genMinus() when the result is the same as left or right

4793 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4795 Made bitfield a distinct type from bit so that bitfields
4796 convert as per ANSI C and bits retain their traditional
4797 boolean style behaviour. Implemented bitfield support in
4805 * src/ds390/gen.c: bit v bitfield split
4806 * src/z80/gen.c: New support for bitfields
4807 * support/regression/tests/bitfields.c: reenabled z80,
4810 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4812 Rules 246.x, 247.x relate to bitfields, the others speed up
4813 access to xdata mapped I/O devices.
4815 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4817 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4819 Cleaned up genPackBits and genUnpackBits and added two helper
4820 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4821 for literal assignments in genPackBits (thanks to Frieder for
4827 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4829 Fixed bug #748310 (pointer to function type mishandled when the
4830 function name is omitted). Also fixed a SIGSEGV when a function
4831 attribute (reentrant, etc) is used on a non-function or on a
4832 function but misplaced before the parameter list.
4834 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
4836 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

4859 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4861 Made the constant following the "interrupt" keyword optional. If
4862 omitted, the function will not automatically be given an entry
4863 in the interrupt vector table (similar to #pragma NOIV, but
4864 less syntacticly kludgy). The interrupt number is also now
4865 range checked. Also fixed a bug in the high order bit example
4872 * support/Util/SDCCerr.c
4873 * support/Util/SDCCerr.h
4876 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

4879 * src/SDCCicode.c (operandOperation): rewritten some ops
4880 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
4881 * src/SDCCsymt.c (computeType): literals are handled the same way as any
4883 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
4884 be re-activated by defining REDUCE_LITERALS)
4885 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
4886 unsigned, but are signed by default
4887 * src/SDCCval.c (constVal): rearranged
4888 * src/SDCCval.c (valMod): preliminary fix
4889 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5344 Using pdflatex this will give you a hyperlinked pdf file with
5345 bookmarks. (prepend '%' before /usepackage if this breaks something)

5386 it can be defined with CFLAGS when running configure
5387 * src/SDCCmain.c: fixed compiling + linking with object files
5389 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

5394 * src/SDCCmain.c: linkOptions is changed to set *,
5395 added if/endif conditional macros to remove options help
5396 messages from optionsTable when a port is not configured, added
5397 support for the PIc16 port in the ports table, when executing
5398 the compiler with no port specified on command line, a default
5399 port is selected with the new macro DEFAULT_PORT which is
5400 defined in port.h, in setDefaultOptions() linkOptions is removed
5401 from initialization assignment, since now it is a set,
5402 parseCmdLine uses setParseWithComma for linkOptions, in
5403 linkEdit() linkOptions are accessed with new function indexSet()
5404 which returns the i'th item of a set variable. See SDCCset.c, in
5405 linkEdit() when calling buildCmdLine(), added linkOptions as
5406 last argument. Now users can pass arguments to gplink via the
5407 -Wl option, main() uses pic16glue() to glue up pic16 programs

5419 * src/pic16/glue.c: commented out some error producing lines
5420 * src/pic16/main.c: __config directives are commented out to stop
5421 gpasm complaining and test the linkage with gplink, _linkCmd and
5422 _asmCmd changed to be more gplink and gpasm friendly
5423 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5424 produced an error when parsed, peep rule 12 is added to utilize
5425 movff, but it is commented out since the pCode does not support
5426 yet a command with 2 address arguments
5428 2003-05-18 <johan AT balder>
5430 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5457 2003-05-11 Borut Razem <borut.razem AT siol.net>
5459 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5460 the path of bin directory, so that PATH is the only env. variable, which has to be set
5461 in case of standard installation.

6555 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6557 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6558 overlaying area for it (uses RegBankUsed[4]).
6560 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6561 bank zero as used by default. By default aslink locates the stack
6562 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6563 the creation of the .mem file. Delegates the allocation of data area
6564 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6565 the begining of the stack area to aslink.
6567 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6568 glue() in SDCCglue.c creates an area for it.
6570 2002-09-03 Borut Razem <borut.razem AT siol.net>
6571 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6572 sdcc/src/pic/glue.c:
6573 introduced atexit() handler for teporay files removal in case of
6574 errors, assertions, ...
6576 2002-08-29 Borut Razem <borut.razem AT siol.net>
6577 * sdcc/support/cpp2/auto-host_vc_in.h:
6578 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6579 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6580 Maybe there is a similar problem with BORLANDC? It should be checked!
6582 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6583 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6584 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6585 was not executed, and the compiler (cl) launched a warning:
6586 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6588 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6589 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6591 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6592 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6594 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6595 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6596 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6597 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6598 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6599 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6600 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6601 - added Release configuration in VS projects
6602 - review of compiler an linker options
6603 - VC .exe files are generated in bin_vc directory, not to interfere
6604 with binaries generated from other projects (cygwin, mingw, bcc ...)
6606 * sdcc/src/yacc.dsp: added
6608 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6609 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6610 and insert the version number definitions from .version
6612 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6614 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6615 added - genarate auto-host.h using auto-host_vc_in.h as template
6618 removed from CVS, generated automatically
6620 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6621 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6623 2002-08-11 Borut Razem <borut.razem AT siol.net>
6624 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6626 2002-08-10 Borut Razem <borut.razem AT siol.net>
6627 * src/SDCCmain.c (main):
6628 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6629 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6630 The consequence was that some temporary files were not removed.
6633 unification of code in functions tempfilename() and tempfile():
6634 function tempnam() is defined in Visual Studio 6.0 and .NET
6636 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6638 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6639 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6640 - removed compiler command line option /WX: Treats all warnings as errors
6641 - update a list of source files, included into the project
6643 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6644 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6645 changed project type to Generic Project so that can be correcly converted to VS.NET project
6647 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6649 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6651 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
6653 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6654 added return 0 statements after assert() to make compiler happy
6656 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6657 added newline in the def file to keep MSC compiler satisfied
6659 * sdcc/src/z80/gen.c:
6660 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6661 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6662 - solved MSC error in function aopDump()
6664 * sdcc_vc.h: define PREFIX as "\\sdcc"
6666 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
6667 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

6715 Added -p option. Allows port dependent processor to be specified.
6718 Initialized the new field char *Processor field to NULL in all ports
6721 Compiler generated registers for interrupt context saving
6722 were not getting allocated.
6724 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
6727 Fixed left shift. Will promote the left side of a left shift
6728 if a) left shifting more than size of operand or b) when assigned
6729 to something size > size of left side
6731 2002-03-14 Scott Dattalo <scott AT dattalo.com>

6841 * sdcc/src/SDCCloop.c:
6842 Previous fix was not good. basic blocks that have "break" or "return" are
6843 not really partof a loop , but live ranges used in these blocks should
6844 be live thru the entire loop, so set partOfLoop but don't add them to
6847 2002-02-21 <johan AT FRIJA>
6849 * src/SDCCcse.c: fixed bug #514308
6851 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

6857 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
6859 2002-02-10 Karl Bongers <karl AT turbobit.com>
