216 * added libc directory. The current version of LibC contains string
217 functions, ctype functions and macros and some functions of the
218 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
219 be extensively tested in the future. Standard disclaimer here.
220 Library is not automatically build yet. But one can build it by

236 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
238 * (genCast): began a fix to optimize the casting of a bit to another
239 bit, now assigning a bitfield to another bitfield will fail, sorry,

3176 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
3178 * src/SDCCast.c: added an additional type flow in decorateType() of
3179 opposite direction, see feature request #860006; it's enabled at runtime
3180 by setting the environment variable SDCC_NEWTYPEFLOW
3181 * src/SDCCast.h: changed prototype of decorateType()
3182 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
3183 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
3184 'char' to 'int' can be omitted, if both operands are 'unsigned char';
3185 see feature request #877103

3214 * src/pic/ralloc.h: applied patch from Slade Rich;
3215 added support for multiple code pages and multiple RAM banks on the
3216 PIC 14 port. The ASM files now no longer simply assume all the
3217 code / RAM are in the same page / bank. This means the linker can
3218 safely allocate code/RAM of separate ASM files to different pages/banks.
3219 * doc/sdccman.lyx: added Slade's tips
3220 * src/mcs51/peeph.def: fixed bug #880768

3262 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3264 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3265 loaded with the linker search paths (-L arguments) and the libraries
3266 to be linked with the current source (-l arguments). Changes
3267 currently will affect only the pic16 port.
3268 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3269 include path the port specific paths and port specific libraries,
3270 * gplink command now contains the $3 argument,
3271 * src/pic16/device.h,
3272 * src/pic16/device.c,: structure PIC_device is made public and
3273 renamed to PIC16_device, the same for variable Pics which is renamed

3288 Documenting changes from previous commits.
3289 * configure.in (version 1.56),
3290 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3291 when generating output files to configure the pic16 library,
3292 but now I've commented it out, since gputils aren't installed in the
3293 SF compile farm, so library won't compile
3295 * device/lib/Makefile.in (version 1.56): initially I've added in
3296 target 'all' the prerequestive 'model-pic16' so it compiled the
3297 pic16 library, but now I've commented it out for the same reasons
3299 * added targets 'model-pic16' and 'objects-pic16' to compile the
3301 * added target 'port-specific-objects-pic16' to handle the
3302 generated libraries and copy them into the build/ directory
3303 * added target 'clean-intermediate-pic16' to clean intermediate
3304 files into pic16 directory
3305 * in target 'installdirs' added line to create directory pic16 in
3306 the installation path
3308 * device/include/Makefile.in (version 1.11): in target 'install'
3309 added lines to copy all header files to installation path,
3310 * in target 'installdirs' added line create directory for pic16
3311 headers in the installation path

3326 * src/z80/main.c (_parseOptions): fixed the portmode= command line
3327 option so that it actually works. Made it specific to the z80, since
3328 the gbz80 doesn't have these kinds of I/O ports.
3330 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3332 * device/include/z180.h,

3356 via literal number. The symbol is placed in the corresponding
3357 position of the data ram
3358 * (pic16_dump_section): relocatable and absolute uninitialized
3359 data are now emitted in sorted order to reduce section naming,
3360 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3361 weren't marked as being in the access bank,
3363 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3365 Added portion of GNU PIC Library under the directory
3366 device/include/pic16 and device/lib/pic16. These files
3367 contain the declarations of SFRs for the PIC18Fxx2 devices.
3368 The directory is initialized via configure from toplevel.

3596 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3598 PIC16 port related changes:
3599 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3600 added variable stackPos,
3602 * gen.c: genCall, assignResultValue: added support for
3603 pushing/retrieving function parameters to/from stack,
3604 genFunction,genEndFunction: setup stack frame for the
3606 genAddrOf: will be changed according to bug 863624
3608 * added files genutils.c and genutils.h which contain gen*
3609 debugged and optimised functions extracted from gen.c
3611 * glue.c: added variable 'externs' which holds extern symbols,
3612 pic16emitRegularMap: is modified to properly handle relocatable
3613 symbols under the new scheme,
3614 pic16createInterruptVect: is modified
3615 pic16printPublics: is modified to emit 'global' assembler directives,
3616 added pic16_printExterns to print extern symbols,
3617 pic16glue: initializes stack/frame pointer in the beginning of
3618 the assembly output. Temporary hack, will be corrected later,
3619 because gplink yet does not support stack and SDCC does not
3620 yet support a type of crt0.o object to create the final binary.
3622 * Removed many lines that contain 8051 legacy code.
3623 * The code is finally placed under a 'code' directive.
3624 * Added port specific options.
3626 * _process_pragma: simplified since now we do not need *special*
3627 include file to define SFR registers. But a separate header
3628 will be needed. This will be developed later.
3629 * _pic16_parseOptions: added, parses port specific options:
3630 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3631 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3632 --preplace-udata-with=
3634 * _pic16_setDefaultOptions: modified to initialize section names,
3635 but hack is temporarly out of order since it needs improvement.
3636 * _pic16_genAssemblerPreamble: configuration words are emitted by
3637 their address instead of their name. This part is incomplete and
3638 supports only the 18Fxx2 devices. Other devices will emit an error
3639 during assembly since they do not contain the same set of config
3641 * _pic16_genIVT: is modified,
3643 * pcode.c: added definitions for some hardware registers that are needed
3645 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3646 All PCI entries are updated. Now LFSR is supported.
3647 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3648 * added pic16_newpCodeOpLit2 to support instructions with
3649 two literal arguments
3650 * pic16_pCode2str: corrected code that emits assembler instructions
3651 with two literal operands and those that have an access bit modifier
3652 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3653 this fixes a bug which caused some labels to be lost, when an
3654 assembler directive was added, i.e. banksel,
3655 * pic16_FixRegisterBanking: improved logic that causes the insertion
3657 * InlineFunction: functions that are called once, are not any more
3658 inlined. This can be a port option in the future,
3660 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3662 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3663 hold the corresponding uninitialized symbols,
3664 * pic16_allocProcessorRegister: registers have explicit marked the
3666 * pic16_allocInternalRegister: registers are explicit marked as
3668 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3669 processing list, so bit registers were lost,
3672 * ralloc.h: added field 'accessBank' and original symbol operand
3673 in register definition,
3674 * removed the field isMapped from register definition,
3676 ** Several functions have been removed from various sources:
3677 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3678 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3679 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3680 pic16_assignRelocatableRegisters
3682 ** others have been introduced:
3683 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3684 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3686 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3688 * support/scripts/inc2h.pl: changed definition of BIT_AT
3689 to emit 'sbit at' instead of 'bit at'. This was a request.
3691 PIC16 port related preliminary changes:
3692 * gen.c: prefixed function popRegFromString with
3693 pic16_ and all references to it corrected
3694 * pcode.c: all pic16_pc_* hardware registers prefixed
3695 with underscore (_),
3696 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3697 * ralloc.c: newReg(): when register is REG_SFR then
3698 set address to rIdx,
3699 pic16_allocProcessorRegister(): marks register wasUsed=0
3700 pic16_writeUsedRegs(): added a call to assign processor
3701 registers via pic16_assignFixedRegisters
3703 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3705 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3706 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3707 variables in unused register banks. Also the SSEG is placed
3708 wherever there is enough space for it, and IDATA can be anywhere
3709 in internal RAM. For now compile using -Wl-Y[stack_size].
3710 The mem file is different for this option as well, since it
3711 makes no sense of talking about DSEG lenght.
3713 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3715 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3716 in certain cases, e.g. when ROM assignment, patch provided
3717 from Albert den Haan.

3960 * src/SDCCast.c (decorateType): disabled a transformation I added in
3961 revision 1.188 (access to fields of a structure at an absolute address);
3962 it breaks with bitfields, extern declarations, and gcse analysis.
3963 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
3964 could be assigned through a pointer, so don't complain.
3965 * src/SDCCast.c (astErrors),

4069 * src/mcs51/main.c: started fixing bug #737001 (SDCC not clearing
4070 uninitialized variables) for the mcs51. Set environment variable

4072 xdata initialization slightly shorter
4074 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4721 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
4722 fetching of the pointer
4723 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
4724 copied from genNearPointerSet()
4725 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
4726 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

4742 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4743 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4744 type for bits was changed. It resulted in bit variables becoming
4745 global, which is not permitted in PIC 14 assembly output.
4747 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4749 * doc/sdccman.lyx: various additions and updates. Rearranged sections

4762 A few small changes that speed up the peephole optimizer.
4766 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4768 Try to make the peephole optimizer smarter by maintaining
4769 an association between the assembly source code and the
4770 iCodes that originated them. Put this information to use
4771 with a new peephole rule condition "notVolatile" so that
4772 the rules can be aggressive yet still safe.
4777 * src/mcs51/peeph.def
4779 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4783 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4784 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4785 if the left or right operand symbols have the accuse flag set.
4787 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4789 Changed the type of the result of the ! (NOT) operator to char;
4790 previously it returned the same type as the source. This allows
4791 us to eliminate all the genFloatNot functions (all of its target
4792 implementations were very buggy) since !float can use the same
4795 * src/SDCCicode.c (ast2iCode): ! returns char

4804 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4805 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4806 during interrupts. Ensure WSAVE is located at a shared bank address.
4807 2. Fixed page selection in some places
4808 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4809 the registers name strings.
4810 4. Fixed "signed / unsigned compare" compiler warnings.
4811 5. The PIC port manages its own allocation of the general purpose
4812 registers, but makes no attempt to reuse them. As a result when
4813 compiling it soon runs out of general purpose registers. Some
4814 additional code was added to the files pcode.c and device.c to walk
4815 through the function call tree and rename the registers so that they
4825 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

4832 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4834 Made bitfield a distinct type from bit so that bitfields
4835 convert as per ANSI C and bits retain their traditional
4836 boolean style behaviour. Implemented bitfield support in
4844 * src/ds390/gen.c: bit v bitfield split
4845 * src/z80/gen.c: New support for bitfields
4846 * support/regression/tests/bitfields.c: reenabled z80,
4849 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4851 Rules 246.x, 247.x relate to bitfields, the others speed up
4852 access to xdata mapped I/O devices.
4854 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4856 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4858 Cleaned up genPackBits and genUnpackBits and added two helper
4859 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4860 for literal assignments in genPackBits (thanks to Frieder for
4866 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4868 Fixed bug #748310 (pointer to function type mishandled when the
4869 function name is omitted). Also fixed a SIGSEGV when a function
4870 attribute (reentrant, etc) is used on a non-function or on a
4871 function but misplaced before the parameter list.
4873 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
4875 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

4898 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4900 Made the constant following the "interrupt" keyword optional. If
4901 omitted, the function will not automatically be given an entry
4902 in the interrupt vector table (similar to #pragma NOIV, but
4903 less syntacticly kludgy). The interrupt number is also now
4904 range checked. Also fixed a bug in the high order bit example

4918 * src/SDCCicode.c (operandOperation): rewritten some ops
4919 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
4920 * src/SDCCsymt.c (computeType): literals are handled the same way as any
4922 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
4923 be re-activated by defining REDUCE_LITERALS)
4924 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
4925 unsigned, but are signed by default
4926 * src/SDCCval.c (constVal): rearranged
4927 * src/SDCCval.c (valMod): preliminary fix
4928 * src/SDCCval.c (valCastLiteral): use TYPE_* types

4970 constants are unsigned; added recognition of "u" flag for unsigned
4971 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
4972 * src/SDCCval.c (valDiv, valMod): fixed signdness
4973 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
4974 signedness of modulo, left and right shift

5433 * src/SDCCmain.c: linkOptions is changed to set *,
5434 added if/endif conditional macros to remove options help
5435 messages from optionsTable when a port is not configured, added
5436 support for the PIc16 port in the ports table, when executing
5437 the compiler with no port specified on command line, a default
5438 port is selected with the new macro DEFAULT_PORT which is
5439 defined in port.h, in setDefaultOptions() linkOptions is removed
5440 from initialization assignment, since now it is a set,
5441 parseCmdLine uses setParseWithComma for linkOptions, in
5442 linkEdit() linkOptions are accessed with new function indexSet()
5443 which returns the i'th item of a set variable. See SDCCset.c, in
5444 linkEdit() when calling buildCmdLine(), added linkOptions as
5445 last argument. Now users can pass arguments to gplink via the
5446 -Wl option, main() uses pic16glue() to glue up pic16 programs

5458 * src/pic16/glue.c: commented out some error producing lines
5459 * src/pic16/main.c: __config directives are commented out to stop
5460 gpasm complaining and test the linkage with gplink, _linkCmd and
5461 _asmCmd changed to be more gplink and gpasm friendly
5462 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5463 produced an error when parsed, peep rule 12 is added to utilize
5464 movff, but it is commented out since the pCode does not support
5465 yet a command with 2 address arguments
5467 2003-05-18 <johan AT balder>
5469 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5496 2003-05-11 Borut Razem <borut.razem AT siol.net>
5498 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5499 the path of bin directory, so that PATH is the only env. variable, which has to be set
5500 in case of standard installation.
5501 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

6553 * SDCClrange.h: exposed setFromRange() and setToRange()
6554 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6555 packRegsForAccUse() (bug 542397)
6556 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6557 multiple times and emitting the fetch operations more than once
6558 added aopGetUsesAcc() function to allow binary operators to
6559 fetch their operands in the correct order; made genMinus() emit
6560 compact code for X = LITERAL - Y
6562 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6563 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6564 sprintf() in line 1267.
6566 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6567 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6570 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6571 Changes to aslink (All the changes are marked with 'JCF'):
6573 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6576 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6577 area BSEG. Also moves, if possible, the DATA area down into the internal
6578 ram so more space is available.
6580 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6583 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6584 not bytes. Function summary() which creates a memory usage summary
6585 file with extension .mem. Reports of overlaping stack and small stack
6586 size. If the space for the stack is less than 16 bytes aslink trows a
6589 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6590 the 8051. Option 'y' for memory summary output file.
6592 Changes to sdcc (All the changes are marked with 'JCF'):
6594 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6596 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6597 overlaying area for it (uses RegBankUsed[4]).
6599 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6600 bank zero as used by default. By default aslink locates the stack
6601 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6602 the creation of the .mem file. Delegates the allocation of data area
6603 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6604 the begining of the stack area to aslink.
6606 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6607 glue() in SDCCglue.c creates an area for it.
6609 2002-09-03 Borut Razem <borut.razem AT siol.net>
6610 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6611 sdcc/src/pic/glue.c:
6612 introduced atexit() handler for teporay files removal in case of
6613 errors, assertions, ...
6615 2002-08-29 Borut Razem <borut.razem AT siol.net>
6616 * sdcc/support/cpp2/auto-host_vc_in.h:
6617 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6618 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6619 Maybe there is a similar problem with BORLANDC? It should be checked!
6621 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6622 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6623 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6624 was not executed, and the compiler (cl) launched a warning:
6625 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6627 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6628 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6630 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6631 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6633 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6634 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6635 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6636 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6637 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6638 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6639 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6640 - added Release configuration in VS projects
6641 - review of compiler an linker options
6642 - VC .exe files are generated in bin_vc directory, not to interfere
6643 with binaries generated from other projects (cygwin, mingw, bcc ...)
6645 * sdcc/src/yacc.dsp: added
6647 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6648 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6649 and insert the version number definitions from .version
6651 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6653 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6654 added - genarate auto-host.h using auto-host_vc_in.h as template
6657 removed from CVS, generated automatically
6659 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6660 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6662 2002-08-11 Borut Razem <borut.razem AT siol.net>
6663 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6665 2002-08-10 Borut Razem <borut.razem AT siol.net>
6666 * src/SDCCmain.c (main):
6667 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6668 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6669 The consequence was that some temporary files were not removed.
6672 unification of code in functions tempfilename() and tempfile():
6673 function tempnam() is defined in Visual Studio 6.0 and .NET
6675 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6677 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6678 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6679 - removed compiler command line option /WX: Treats all warnings as errors
6680 - update a list of source files, included into the project
6682 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6683 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6684 changed project type to Generic Project so that can be correcly converted to VS.NET project
6686 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6688 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6690 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
6692 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6693 added return 0 statements after assert() to make compiler happy
6695 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6696 added newline in the def file to keep MSC compiler satisfied
6698 * sdcc/src/z80/gen.c:
6699 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6700 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6701 - solved MSC error in function aopDump()
6703 * sdcc_vc.h: define PREFIX as "\\sdcc"
6705 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
6706 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

6709 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
6710 - Rewrote the register banking algorithm.
6711 - Added pCode live-range analysis to registers (for now, only non-used and
6712 singly-used registers optimized away)
6714 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis

6745 2002-03-28 Johan Knol <johan AT balder>
6747 * src/SDCCval.c: fixed bug #532436
6749 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6751 Added "char *Processor" field to the port structure.
6754 Added -p option. Allows port dependent processor to be specified.
6757 Initialized the new field char *Processor field to NULL in all ports
6760 Compiler generated registers for interrupt context saving
6761 were not getting allocated.
6763 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
6766 Fixed left shift. Will promote the left side of a left shift
6767 if a) left shifting more than size of operand or b) when assigned
6768 to something size > size of left side
6770 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6772 tons of changes. Register allocation has been
6773 rewritten. Added customization for the various PICs. Flow

6878 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
6880 * sdcc/src/SDCCloop.c:
6881 Previous fix was not good. basic blocks that have "break" or "return" are
6882 not really partof a loop , but live ranges used in these blocks should
6883 be live thru the entire loop, so set partOfLoop but don't add them to
6886 2002-02-21 <johan AT FRIJA>
6888 * src/SDCCcse.c: fixed bug #514308
6890 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
6893 Fixed BUG #519583. If a conditional block ended in a return/break
6894 statement inside a loop, it was not being considered part of the loop.
6896 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
6898 2002-02-10 Karl Bongers <karl AT turbobit.com>
6901 Fixed up SDCDB debugger somewhat. Updated debugger/README
6902 with lots of comments and notes.
6904 * device/examples/test2.c:
6905 Fix bug, "red" variable not being initialized(compiler complained).
