146 Adding support for replacing ljmps with sjmps in jumptables
147 generated for switch statements. For now you need to set the
148 environment variable SDCC_SJMP_JUMPTABLE to enable this.
149 Now 4 algorithms for mcs51 jumptable generation are used:
150 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

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

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

3146 * src/SDCCast.c: added an additional type flow in decorateType() of
3147 opposite direction, see feature request #860006; it's enabled at runtime
3148 by setting the environment variable SDCC_NEWTYPEFLOW
3149 * src/SDCCast.h: changed prototype of decorateType()
3150 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
3151 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
3152 'char' to 'int' can be omitted, if both operands are 'unsigned char';
3153 see feature request #877103
3154 * src/SDCCval.c: updated call of decorateType()
3155 (valBitwise): fixed bug #882876
3156 (valMinus): added promotion
3157 (valLogicAndOr): result is unsigned
3158 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
3159 * src/SDCCsymt.c (computeType),
3160 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
3161 must not cause an unsigned operation
3162 * src/pic/glue (pic14emitRegularMap),
3163 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
3165 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>
3167 * src/pic/pcode.c (PCodeID): commented out left over debug code
3169 2004-01-20 Bernhard Held <bernhard AT bernhardheld.de>
3171 * support/valdiag/tests/overflow.c: added shift tests

3180 * src/pic/pcoderegs.c,
3182 * src/pic/ralloc.h: applied patch from Slade Rich;
3183 added support for multiple code pages and multiple RAM banks on the
3184 PIC 14 port. The ASM files now no longer simply assume all the
3185 code / RAM are in the same page / bank. This means the linker can
3186 safely allocate code/RAM of separate ASM files to different pages/banks.
3187 * doc/sdccman.lyx: added Slade's tips
3188 * src/mcs51/peeph.def: fixed bug #880768

3197 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
3200 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
3201 strtof is not part of C89 and isn't included with Mac OS X.
3203 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3205 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

3227 * src/ds390/gen.c (aopOp3): fixed the assignment of different dptrs to
3230 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3232 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3233 loaded with the linker search paths (-L arguments) and the libraries
3234 to be linked with the current source (-l arguments). Changes
3235 currently will affect only the pic16 port.
3236 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3237 include path the port specific paths and port specific libraries,
3238 * gplink command now contains the $3 argument,
3239 * src/pic16/device.h,
3240 * src/pic16/device.c,: structure PIC_device is made public and
3241 renamed to PIC16_device, the same for variable Pics which is renamed
3242 to Pics16. Updated all references to them.

3254 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
3256 Documenting changes from previous commits.
3257 * configure.in (version 1.56),
3258 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3259 when generating output files to configure the pic16 library,
3260 but now I've commented it out, since gputils aren't installed in the
3261 SF compile farm, so library won't compile
3263 * device/lib/Makefile.in (version 1.56): initially I've added in
3264 target 'all' the prerequestive 'model-pic16' so it compiled the
3265 pic16 library, but now I've commented it out for the same reasons
3267 * added targets 'model-pic16' and 'objects-pic16' to compile the
3269 * added target 'port-specific-objects-pic16' to handle the
3270 generated libraries and copy them into the build/ directory
3271 * added target 'clean-intermediate-pic16' to clean intermediate
3272 files into pic16 directory
3273 * in target 'installdirs' added line to create directory pic16 in
3274 the installation path
3276 * device/include/Makefile.in (version 1.11): in target 'install'
3277 added lines to copy all header files to installation path,
3278 * in target 'installdirs' added line create directory for pic16
3279 headers in the installation path

3294 * src/z80/main.c (_parseOptions): fixed the portmode= command line
3295 option so that it actually works. Made it specific to the z80, since
3296 the gbz80 doesn't have these kinds of I/O ports.
3298 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3300 * device/include/z180.h,

3322 Mainly changes to support compilation of the device libraries
3323 * src/pic16/device.c: stack is allocated via symbol and not
3324 via literal number. The symbol is placed in the corresponding
3325 position of the data ram
3326 * (pic16_dump_section): relocatable and absolute uninitialized
3327 data are now emitted in sorted order to reduce section naming,
3328 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3329 weren't marked as being in the access bank,
3331 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3333 Added portion of GNU PIC Library under the directory
3334 device/include/pic16 and device/lib/pic16. These files
3335 contain the declarations of SFRs for the PIC18Fxx2 devices.
3336 The directory is initialized via configure from toplevel.
3338 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
3340 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

3352 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
3354 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
3355 in simpler and even better code

3365 * doc/sdccman.lyx: Moved and added some sections, small changes
3366 all over. Telling LaTeX to be less strict with word spacing
3367 to better keep the right margin. Changed some notes about
3368 maintainance of the ports in section 3.2.1 - is it OK like this?
3370 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

3408 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
3410 * src/pic16/peeph.def: all peepholes with movff are commented out,
3411 because there is a problem in the pcode peep optimizer,
3412 * src/pic16/ralloc.c: the register allocator can now reuse local

3551 Bug reported from Jesus Calvino-Fraga
3553 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3555 * sdcc.spec: updated
3556 * device/include/Makefile.in: don't install CVS directories

3561 * src/ds390/gen.c (genRightShift): fixed bug #870788
3562 * src/SDCCast.c (decorateType): fixed bug #870781
3564 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3566 PIC16 port related changes:
3567 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3568 added variable stackPos,
3570 * gen.c: genCall, assignResultValue: added support for
3571 pushing/retrieving function parameters to/from stack,
3572 genFunction,genEndFunction: setup stack frame for the
3574 genAddrOf: will be changed according to bug 863624
3576 * added files genutils.c and genutils.h which contain gen*
3577 debugged and optimised functions extracted from gen.c
3579 * glue.c: added variable 'externs' which holds extern symbols,
3580 pic16emitRegularMap: is modified to properly handle relocatable
3581 symbols under the new scheme,
3582 pic16createInterruptVect: is modified
3583 pic16printPublics: is modified to emit 'global' assembler directives,
3584 added pic16_printExterns to print extern symbols,
3585 pic16glue: initializes stack/frame pointer in the beginning of
3586 the assembly output. Temporary hack, will be corrected later,
3587 because gplink yet does not support stack and SDCC does not
3588 yet support a type of crt0.o object to create the final binary.
3590 * Removed many lines that contain 8051 legacy code.
3591 * The code is finally placed under a 'code' directive.
3592 * Added port specific options.
3594 * _process_pragma: simplified since now we do not need *special*
3595 include file to define SFR registers. But a separate header
3596 will be needed. This will be developed later.
3597 * _pic16_parseOptions: added, parses port specific options:
3598 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3599 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3600 --preplace-udata-with=
3602 * _pic16_setDefaultOptions: modified to initialize section names,
3603 but hack is temporarly out of order since it needs improvement.
3604 * _pic16_genAssemblerPreamble: configuration words are emitted by
3605 their address instead of their name. This part is incomplete and
3606 supports only the 18Fxx2 devices. Other devices will emit an error
3607 during assembly since they do not contain the same set of config
3609 * _pic16_genIVT: is modified,
3611 * pcode.c: added definitions for some hardware registers that are needed
3613 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3614 All PCI entries are updated. Now LFSR is supported.
3615 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3616 * added pic16_newpCodeOpLit2 to support instructions with
3617 two literal arguments
3618 * pic16_pCode2str: corrected code that emits assembler instructions
3619 with two literal operands and those that have an access bit modifier
3620 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3621 this fixes a bug which caused some labels to be lost, when an
3622 assembler directive was added, i.e. banksel,
3623 * pic16_FixRegisterBanking: improved logic that causes the insertion
3625 * InlineFunction: functions that are called once, are not any more
3626 inlined. This can be a port option in the future,
3628 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3630 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3631 hold the corresponding uninitialized symbols,
3632 * pic16_allocProcessorRegister: registers have explicit marked the
3634 * pic16_allocInternalRegister: registers are explicit marked as
3636 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3637 processing list, so bit registers were lost,
3640 * ralloc.h: added field 'accessBank' and original symbol operand
3641 in register definition,
3642 * removed the field isMapped from register definition,
3644 ** Several functions have been removed from various sources:
3645 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3646 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3647 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3648 pic16_assignRelocatableRegisters
3650 ** others have been introduced:
3651 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3652 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3654 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3656 * support/scripts/inc2h.pl: changed definition of BIT_AT
3657 to emit 'sbit at' instead of 'bit at'. This was a request.
3659 PIC16 port related preliminary changes:
3660 * gen.c: prefixed function popRegFromString with
3661 pic16_ and all references to it corrected
3662 * pcode.c: all pic16_pc_* hardware registers prefixed
3663 with underscore (_),
3664 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3665 * ralloc.c: newReg(): when register is REG_SFR then
3666 set address to rIdx,
3667 pic16_allocProcessorRegister(): marks register wasUsed=0
3668 pic16_writeUsedRegs(): added a call to assign processor
3669 registers via pic16_assignFixedRegisters
3671 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3673 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3674 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3675 variables in unused register banks. Also the SSEG is placed
3676 wherever there is enough space for it, and IDATA can be anywhere
3677 in internal RAM. For now compile using -Wl-Y[stack_size].
3678 The mem file is different for this option as well, since it
3679 makes no sense of talking about DSEG lenght.
3681 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3683 * src/SDCClrange.c: fixed bug 869095 that caused segfault

3929 revision 1.188 (access to fields of a structure at an absolute address);
3930 it breaks with bitfields, extern declarations, and gcse analysis.
3931 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
3932 could be assigned through a pointer, so don't complain.

4689 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
4690 fetching of the pointer
4691 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
4692 copied from genNearPointerSet()
4693 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
4694 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
4695 If they pop r0/r1 they must be called in the opposite order than aopOp().

4708 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
4710 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4711 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4712 type for bits was changed. It resulted in bit variables becoming
4713 global, which is not permitted in PIC 14 assembly output.
4715 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4717 * doc/sdccman.lyx: various additions and updates. Rearranged sections

4730 A few small changes that speed up the peephole optimizer.
4734 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4736 Try to make the peephole optimizer smarter by maintaining
4737 an association between the assembly source code and the
4738 iCodes that originated them. Put this information to use
4739 with a new peephole rule condition "notVolatile" so that
4740 the rules can be aggressive yet still safe.
4745 * src/mcs51/peeph.def
4747 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4751 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4752 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4753 if the left or right operand symbols have the accuse flag set.
4755 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4757 Changed the type of the result of the ! (NOT) operator to char;
4758 previously it returned the same type as the source. This allows
4759 us to eliminate all the genFloatNot functions (all of its target
4760 implementations were very buggy) since !float can use the same
4763 * src/SDCCicode.c (ast2iCode): ! returns char

4772 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4773 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4774 during interrupts. Ensure WSAVE is located at a shared bank address.
4775 2. Fixed page selection in some places
4776 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4777 the registers name strings.
4778 4. Fixed "signed / unsigned compare" compiler warnings.
4779 5. The PIC port manages its own allocation of the general purpose
4780 registers, but makes no attempt to reuse them. As a result when
4781 compiling it soon runs out of general purpose registers. Some
4782 additional code was added to the files pcode.c and device.c to walk
4783 through the function call tree and rename the registers so that they
4793 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
4794 genPlus() & genMinus() when the result is the same as left or right

4800 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4802 Made bitfield a distinct type from bit so that bitfields
4803 convert as per ANSI C and bits retain their traditional
4804 boolean style behaviour. Implemented bitfield support in
4812 * src/ds390/gen.c: bit v bitfield split
4813 * src/z80/gen.c: New support for bitfields
4814 * support/regression/tests/bitfields.c: reenabled z80,
4817 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4819 Rules 246.x, 247.x relate to bitfields, the others speed up
4820 access to xdata mapped I/O devices.
4822 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4824 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4826 Cleaned up genPackBits and genUnpackBits and added two helper
4827 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4828 for literal assignments in genPackBits (thanks to Frieder for
4834 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4836 Fixed bug #748310 (pointer to function type mishandled when the
4837 function name is omitted). Also fixed a SIGSEGV when a function
4838 attribute (reentrant, etc) is used on a non-function or on a
4839 function but misplaced before the parameter list.
4841 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
4843 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

4866 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4868 Made the constant following the "interrupt" keyword optional. If
4869 omitted, the function will not automatically be given an entry
4870 in the interrupt vector table (similar to #pragma NOIV, but
4871 less syntacticly kludgy). The interrupt number is also now
4872 range checked. Also fixed a bug in the high order bit example

4886 * src/SDCCicode.c (operandOperation): rewritten some ops
4887 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
4888 * src/SDCCsymt.c (computeType): literals are handled the same way as any
4890 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
4891 be re-activated by defining REDUCE_LITERALS)
4892 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
4893 unsigned, but are signed by default
4894 * src/SDCCval.c (constVal): rearranged
4895 * src/SDCCval.c (valMod): preliminary fix
4896 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5348 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
5349 the regression tests I'm not brave enough to enable 245.b, 245.c
5350 * doc/sdccman.lyx: added latex preamble for hyperref package.
5351 Using pdflatex this will give you a hyperlinked pdf file with
5352 bookmarks. (prepend '%' before /usepackage if this breaks something)

5393 it can be defined with CFLAGS when running configure
5394 * src/SDCCmain.c: fixed compiling + linking with object files
5396 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

5401 * src/SDCCmain.c: linkOptions is changed to set *,
5402 added if/endif conditional macros to remove options help
5403 messages from optionsTable when a port is not configured, added
5404 support for the PIc16 port in the ports table, when executing
5405 the compiler with no port specified on command line, a default
5406 port is selected with the new macro DEFAULT_PORT which is
5407 defined in port.h, in setDefaultOptions() linkOptions is removed
5408 from initialization assignment, since now it is a set,
5409 parseCmdLine uses setParseWithComma for linkOptions, in
5410 linkEdit() linkOptions are accessed with new function indexSet()
5411 which returns the i'th item of a set variable. See SDCCset.c, in
5412 linkEdit() when calling buildCmdLine(), added linkOptions as
5413 last argument. Now users can pass arguments to gplink via the
5414 -Wl option, main() uses pic16glue() to glue up pic16 programs

5426 * src/pic16/glue.c: commented out some error producing lines
5427 * src/pic16/main.c: __config directives are commented out to stop
5428 gpasm complaining and test the linkage with gplink, _linkCmd and
5429 _asmCmd changed to be more gplink and gpasm friendly
5430 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5431 produced an error when parsed, peep rule 12 is added to utilize
5432 movff, but it is commented out since the pCode does not support
5433 yet a command with 2 address arguments
5435 2003-05-18 <johan AT balder>
5437 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5464 2003-05-11 Borut Razem <borut.razem AT siol.net>
5466 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5467 the path of bin directory, so that PATH is the only env. variable, which has to be set
5468 in case of standard installation.

6551 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6552 not bytes. Function summary() which creates a memory usage summary
6553 file with extension .mem. Reports of overlaping stack and small stack
6554 size. If the space for the stack is less than 16 bytes aslink trows a
6557 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6558 the 8051. Option 'y' for memory summary output file.
6560 Changes to sdcc (All the changes are marked with 'JCF'):
6562 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6564 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6565 overlaying area for it (uses RegBankUsed[4]).
6567 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6568 bank zero as used by default. By default aslink locates the stack
6569 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6570 the creation of the .mem file. Delegates the allocation of data area
6571 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6572 the begining of the stack area to aslink.
6574 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6575 glue() in SDCCglue.c creates an area for it.
6577 2002-09-03 Borut Razem <borut.razem AT siol.net>
6578 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6579 sdcc/src/pic/glue.c:
6580 introduced atexit() handler for teporay files removal in case of
6581 errors, assertions, ...
6583 2002-08-29 Borut Razem <borut.razem AT siol.net>
6584 * sdcc/support/cpp2/auto-host_vc_in.h:
6585 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6586 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6587 Maybe there is a similar problem with BORLANDC? It should be checked!
6589 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6590 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6591 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6592 was not executed, and the compiler (cl) launched a warning:
6593 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6595 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6596 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6598 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6599 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6601 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6602 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6603 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6604 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6605 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6606 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6607 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6608 - added Release configuration in VS projects
6609 - review of compiler an linker options
6610 - VC .exe files are generated in bin_vc directory, not to interfere
6611 with binaries generated from other projects (cygwin, mingw, bcc ...)
6613 * sdcc/src/yacc.dsp: added
6615 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6616 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6617 and insert the version number definitions from .version
6619 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6621 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6622 added - genarate auto-host.h using auto-host_vc_in.h as template
6625 removed from CVS, generated automatically

6628 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6630 2002-08-11 Borut Razem <borut.razem AT siol.net>
6631 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6633 2002-08-10 Borut Razem <borut.razem AT siol.net>
6634 * src/SDCCmain.c (main):
6635 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6636 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6637 The consequence was that some temporary files were not removed.
6640 unification of code in functions tempfilename() and tempfile():
6641 function tempnam() is defined in Visual Studio 6.0 and .NET
6643 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6645 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6646 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6647 - removed compiler command line option /WX: Treats all warnings as errors
6648 - update a list of source files, included into the project
6650 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6651 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6652 changed project type to Generic Project so that can be correcly converted to VS.NET project
6654 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6656 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6658 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
6660 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6661 added return 0 statements after assert() to make compiler happy
6663 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6664 added newline in the def file to keep MSC compiler satisfied
6666 * sdcc/src/z80/gen.c:
6667 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6668 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6669 - solved MSC error in function aopDump()
6671 * sdcc_vc.h: define PREFIX as "\\sdcc"
6673 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
6674 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

6725 Initialized the new field char *Processor field to NULL in all ports
6728 Compiler generated registers for interrupt context saving
6729 were not getting allocated.
6731 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
6734 Fixed left shift. Will promote the left side of a left shift
6735 if a) left shifting more than size of operand or b) when assigned
6736 to something size > size of left side
6738 2002-03-14 Scott Dattalo <scott AT dattalo.com>

6848 * sdcc/src/SDCCloop.c:
6849 Previous fix was not good. basic blocks that have "break" or "return" are
6850 not really partof a loop , but live ranges used in these blocks should
6851 be live thru the entire loop, so set partOfLoop but don't add them to
6854 2002-02-21 <johan AT FRIJA>
6856 * src/SDCCcse.c: fixed bug #514308
6858 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

6864 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
6866 2002-02-10 Karl Bongers <karl AT turbobit.com>
