204 * added libc directory. The current version of LibC contains string
205 functions, ctype functions and macros and some functions of the
206 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
207 be extensively tested in the future. Standard disclaimer here.

223 with variables grater than 1 byte in size, so new code is disabled,
224 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
226 * (genCast): began a fix to optimize the casting of a bit to another
227 bit, now assigning a bitfield to another bitfield will fail, sorry,

3138 2004-01-27 Bernhard Held <bernhard AT bernhardheld.de>
3140 Fixed promotion, it should be done on AST level:
3141 * src/SDCCast.c (addCast): added promotion to int
3142 (decorateType): updated call to upCast()
3143 * src/SDCCicode.c (geniCodeLeftShift): removed call to
3144 usualUnaryConversions()
3146 2004-01-26 Michael Hope <michaelh AT juju.net.nz>
3148 * support/regression/tests/literalop.c (mulWrapper): Added a
3149 wrapper to remove integer overflow warnings.

3153 * support/regression/ports/ucz80/spec.mk (UCZ80): Made detect the
3156 * support/regression/generate-cases.py (main): Changed from inline
3159 * doc/Makefile (install): Changed to depth first to get rid of
3160 missing directory install warning.
3162 * as/Makefile (install-doc): Made work on Mac.
3164 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
3166 * src/SDCCast.c: added an additional type flow in decorateType() of
3167 opposite direction, see feature request #860006; it's enabled at runtime
3168 by setting the environment variable SDCC_NEWTYPEFLOW
3169 * src/SDCCast.h: changed prototype of decorateType()
3170 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
3171 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
3172 'char' to 'int' can be omitted, if both operands are 'unsigned char';
3173 see feature request #877103
3174 * src/SDCCval.c: updated call of decorateType()
3175 (valBitwise): fixed bug #882876
3176 (valMinus): added promotion
3177 (valLogicAndOr): result is unsigned
3178 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
3179 * src/SDCCsymt.c (computeType),
3180 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
3181 must not cause an unsigned operation

3202 * src/pic/ralloc.h: applied patch from Slade Rich;
3203 added support for multiple code pages and multiple RAM banks on the
3204 PIC 14 port. The ASM files now no longer simply assume all the
3205 code / RAM are in the same page / bank. This means the linker can
3206 safely allocate code/RAM of separate ASM files to different pages/banks.
3207 * doc/sdccman.lyx: added Slade's tips
3208 * src/mcs51/peeph.def: fixed bug #880768

3220 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
3221 strtof is not part of C89 and isn't included with Mac OS X.
3223 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3225 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

3250 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3252 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3253 loaded with the linker search paths (-L arguments) and the libraries
3254 to be linked with the current source (-l arguments). Changes
3255 currently will affect only the pic16 port.
3256 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3257 include path the port specific paths and port specific libraries,
3258 * gplink command now contains the $3 argument,
3259 * src/pic16/device.h,
3260 * src/pic16/device.c,: structure PIC_device is made public and
3261 renamed to PIC16_device, the same for variable Pics which is renamed

3276 Documenting changes from previous commits.
3277 * configure.in (version 1.56),
3278 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3279 when generating output files to configure the pic16 library,
3280 but now I've commented it out, since gputils aren't installed in the
3281 SF compile farm, so library won't compile
3283 * device/lib/Makefile.in (version 1.56): initially I've added in
3284 target 'all' the prerequestive 'model-pic16' so it compiled the
3285 pic16 library, but now I've commented it out for the same reasons
3287 * added targets 'model-pic16' and 'objects-pic16' to compile the
3289 * added target 'port-specific-objects-pic16' to handle the
3290 generated libraries and copy them into the build/ directory
3291 * added target 'clean-intermediate-pic16' to clean intermediate
3292 files into pic16 directory
3293 * in target 'installdirs' added line to create directory pic16 in
3294 the installation path
3296 * device/include/Makefile.in (version 1.11): in target 'install'
3297 added lines to copy all header files to installation path,
3298 * in target 'installdirs' added line create directory for pic16
3299 headers in the installation path

3314 * src/z80/main.c (_parseOptions): fixed the portmode= command line
3315 option so that it actually works. Made it specific to the z80, since
3316 the gbz80 doesn't have these kinds of I/O ports.
3318 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3320 * device/include/z180.h,

3342 Mainly changes to support compilation of the device libraries
3343 * src/pic16/device.c: stack is allocated via symbol and not
3344 via literal number. The symbol is placed in the corresponding
3345 position of the data ram
3346 * (pic16_dump_section): relocatable and absolute uninitialized
3347 data are now emitted in sorted order to reduce section naming,
3348 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3349 weren't marked as being in the access bank,
3351 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3353 Added portion of GNU PIC Library under the directory
3354 device/include/pic16 and device/lib/pic16. These files
3355 contain the declarations of SFRs for the PIC18Fxx2 devices.
3356 The directory is initialized via configure from toplevel.

3386 all over. Telling LaTeX to be less strict with word spacing
3387 to better keep the right margin. Changed some notes about
3388 maintainance of the ports in section 3.2.1 - is it OK like this?
3390 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

3430 * src/pic16/peeph.def: all peepholes with movff are commented out,
3431 because there is a problem in the pcode peep optimizer,
3432 * src/pic16/ralloc.c: the register allocator can now reuse local

3584 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3586 PIC16 port related changes:
3587 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3588 added variable stackPos,
3590 * gen.c: genCall, assignResultValue: added support for
3591 pushing/retrieving function parameters to/from stack,
3592 genFunction,genEndFunction: setup stack frame for the
3594 genAddrOf: will be changed according to bug 863624
3596 * added files genutils.c and genutils.h which contain gen*
3597 debugged and optimised functions extracted from gen.c
3599 * glue.c: added variable 'externs' which holds extern symbols,
3600 pic16emitRegularMap: is modified to properly handle relocatable
3601 symbols under the new scheme,
3602 pic16createInterruptVect: is modified
3603 pic16printPublics: is modified to emit 'global' assembler directives,
3604 added pic16_printExterns to print extern symbols,
3605 pic16glue: initializes stack/frame pointer in the beginning of
3606 the assembly output. Temporary hack, will be corrected later,
3607 because gplink yet does not support stack and SDCC does not
3608 yet support a type of crt0.o object to create the final binary.
3610 * Removed many lines that contain 8051 legacy code.
3611 * The code is finally placed under a 'code' directive.
3612 * Added port specific options.
3614 * _process_pragma: simplified since now we do not need *special*
3615 include file to define SFR registers. But a separate header
3616 will be needed. This will be developed later.
3617 * _pic16_parseOptions: added, parses port specific options:
3618 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3619 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3620 --preplace-udata-with=
3622 * _pic16_setDefaultOptions: modified to initialize section names,
3623 but hack is temporarly out of order since it needs improvement.
3624 * _pic16_genAssemblerPreamble: configuration words are emitted by
3625 their address instead of their name. This part is incomplete and
3626 supports only the 18Fxx2 devices. Other devices will emit an error
3627 during assembly since they do not contain the same set of config
3629 * _pic16_genIVT: is modified,
3631 * pcode.c: added definitions for some hardware registers that are needed
3633 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3634 All PCI entries are updated. Now LFSR is supported.
3635 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3636 * added pic16_newpCodeOpLit2 to support instructions with
3637 two literal arguments
3638 * pic16_pCode2str: corrected code that emits assembler instructions
3639 with two literal operands and those that have an access bit modifier
3640 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3641 this fixes a bug which caused some labels to be lost, when an
3642 assembler directive was added, i.e. banksel,
3643 * pic16_FixRegisterBanking: improved logic that causes the insertion
3645 * InlineFunction: functions that are called once, are not any more
3646 inlined. This can be a port option in the future,
3648 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3650 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3651 hold the corresponding uninitialized symbols,
3652 * pic16_allocProcessorRegister: registers have explicit marked the
3654 * pic16_allocInternalRegister: registers are explicit marked as
3656 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3657 processing list, so bit registers were lost,
3660 * ralloc.h: added field 'accessBank' and original symbol operand
3661 in register definition,
3662 * removed the field isMapped from register definition,
3664 ** Several functions have been removed from various sources:
3665 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3666 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3667 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3668 pic16_assignRelocatableRegisters
3670 ** others have been introduced:
3671 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3672 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3674 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3676 * support/scripts/inc2h.pl: changed definition of BIT_AT
3677 to emit 'sbit at' instead of 'bit at'. This was a request.
3679 PIC16 port related preliminary changes:
3680 * gen.c: prefixed function popRegFromString with
3681 pic16_ and all references to it corrected
3682 * pcode.c: all pic16_pc_* hardware registers prefixed
3683 with underscore (_),
3684 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3685 * ralloc.c: newReg(): when register is REG_SFR then
3686 set address to rIdx,
3687 pic16_allocProcessorRegister(): marks register wasUsed=0
3688 pic16_writeUsedRegs(): added a call to assign processor
3689 registers via pic16_assignFixedRegisters
3691 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3693 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3694 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3695 variables in unused register banks. Also the SSEG is placed
3696 wherever there is enough space for it, and IDATA can be anywhere
3697 in internal RAM. For now compile using -Wl-Y[stack_size].
3698 The mem file is different for this option as well, since it
3699 makes no sense of talking about DSEG lenght.
3701 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3703 * src/SDCClrange.c: fixed bug 869095 that caused segfault

3948 * src/SDCCast.c (decorateType): disabled a transformation I added in
3949 revision 1.188 (access to fields of a structure at an absolute address);
3950 it breaks with bitfields, extern declarations, and gcse analysis.
3951 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
3952 could be assigned through a pointer, so don't complain.

4060 xdata initialization slightly shorter
4062 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4711 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
4712 copied from genNearPointerSet()
4713 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
4714 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

4730 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4731 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4732 type for bits was changed. It resulted in bit variables becoming
4733 global, which is not permitted in PIC 14 assembly output.
4735 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4737 * doc/sdccman.lyx: various additions and updates. Rearranged sections

4750 A few small changes that speed up the peephole optimizer.
4754 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4756 Try to make the peephole optimizer smarter by maintaining
4757 an association between the assembly source code and the
4758 iCodes that originated them. Put this information to use
4759 with a new peephole rule condition "notVolatile" so that
4760 the rules can be aggressive yet still safe.
4765 * src/mcs51/peeph.def
4767 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4771 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4772 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4773 if the left or right operand symbols have the accuse flag set.
4775 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4777 Changed the type of the result of the ! (NOT) operator to char;
4778 previously it returned the same type as the source. This allows
4779 us to eliminate all the genFloatNot functions (all of its target
4780 implementations were very buggy) since !float can use the same
4783 * src/SDCCicode.c (ast2iCode): ! returns char

4790 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
4792 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4793 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4794 during interrupts. Ensure WSAVE is located at a shared bank address.
4795 2. Fixed page selection in some places
4796 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4797 the registers name strings.
4798 4. Fixed "signed / unsigned compare" compiler warnings.
4799 5. The PIC port manages its own allocation of the general purpose
4800 registers, but makes no attempt to reuse them. As a result when
4801 compiling it soon runs out of general purpose registers. Some
4802 additional code was added to the files pcode.c and device.c to walk
4803 through the function call tree and rename the registers so that they
4813 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
4814 genPlus() & genMinus() when the result is the same as left or right

4820 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4822 Made bitfield a distinct type from bit so that bitfields
4823 convert as per ANSI C and bits retain their traditional
4824 boolean style behaviour. Implemented bitfield support in
4832 * src/ds390/gen.c: bit v bitfield split
4833 * src/z80/gen.c: New support for bitfields
4834 * support/regression/tests/bitfields.c: reenabled z80,
4837 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4839 Rules 246.x, 247.x relate to bitfields, the others speed up
4840 access to xdata mapped I/O devices.
4842 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4844 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4846 Cleaned up genPackBits and genUnpackBits and added two helper
4847 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4848 for literal assignments in genPackBits (thanks to Frieder for
4854 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4856 Fixed bug #748310 (pointer to function type mishandled when the
4857 function name is omitted). Also fixed a SIGSEGV when a function
4858 attribute (reentrant, etc) is used on a non-function or on a
4859 function but misplaced before the parameter list.
4861 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
4863 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
4864 * support/Util/SDCCerr.h,
4865 * support/Util/SDCCerr.c: Added func attr misuse error msg

4886 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4888 Made the constant following the "interrupt" keyword optional. If
4889 omitted, the function will not automatically be given an entry
4890 in the interrupt vector table (similar to #pragma NOIV, but
4891 less syntacticly kludgy). The interrupt number is also now
4892 range checked. Also fixed a bug in the high order bit example
4899 * support/Util/SDCCerr.c
4900 * support/Util/SDCCerr.h
4903 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

4906 * src/SDCCicode.c (operandOperation): rewritten some ops
4907 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
4908 * src/SDCCsymt.c (computeType): literals are handled the same way as any
4910 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
4911 be re-activated by defining REDUCE_LITERALS)
4912 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
4913 unsigned, but are signed by default
4914 * src/SDCCval.c (constVal): rearranged
4915 * src/SDCCval.c (valMod): preliminary fix
4916 * src/SDCCval.c (valCastLiteral): use TYPE_* types

4958 constants are unsigned; added recognition of "u" flag for unsigned
4959 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
4960 * src/SDCCval.c (valDiv, valMod): fixed signdness
4961 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
4962 signedness of modulo, left and right shift

5371 Using pdflatex this will give you a hyperlinked pdf file with
5372 bookmarks. (prepend '%' before /usepackage if this breaks something)

5419 added --disable-pic16-port
5420 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
5421 * src/SDCCmain.c: linkOptions is changed to set *,
5422 added if/endif conditional macros to remove options help
5423 messages from optionsTable when a port is not configured, added
5424 support for the PIc16 port in the ports table, when executing
5425 the compiler with no port specified on command line, a default
5426 port is selected with the new macro DEFAULT_PORT which is
5427 defined in port.h, in setDefaultOptions() linkOptions is removed
5428 from initialization assignment, since now it is a set,
5429 parseCmdLine uses setParseWithComma for linkOptions, in
5430 linkEdit() linkOptions are accessed with new function indexSet()
5431 which returns the i'th item of a set variable. See SDCCset.c, in
5432 linkEdit() when calling buildCmdLine(), added linkOptions as
5433 last argument. Now users can pass arguments to gplink via the
5434 -Wl option, main() uses pic16glue() to glue up pic16 programs

5446 * src/pic16/glue.c: commented out some error producing lines
5447 * src/pic16/main.c: __config directives are commented out to stop
5448 gpasm complaining and test the linkage with gplink, _linkCmd and
5449 _asmCmd changed to be more gplink and gpasm friendly
5450 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5451 produced an error when parsed, peep rule 12 is added to utilize
5452 movff, but it is commented out since the pCode does not support
5453 yet a command with 2 address arguments
5455 2003-05-18 <johan AT balder>
5457 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5484 2003-05-11 Borut Razem <borut.razem AT siol.net>
5486 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5487 the path of bin directory, so that PATH is the only env. variable, which has to be set
5488 in case of standard installation.

6555 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6558 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6559 Changes to aslink (All the changes are marked with 'JCF'):
6561 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6564 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6565 area BSEG. Also moves, if possible, the DATA area down into the internal
6566 ram so more space is available.
6568 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6571 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6572 not bytes. Function summary() which creates a memory usage summary
6573 file with extension .mem. Reports of overlaping stack and small stack
6574 size. If the space for the stack is less than 16 bytes aslink trows a
6577 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6578 the 8051. Option 'y' for memory summary output file.
6580 Changes to sdcc (All the changes are marked with 'JCF'):
6582 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6584 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6585 overlaying area for it (uses RegBankUsed[4]).
6587 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6588 bank zero as used by default. By default aslink locates the stack
6589 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6590 the creation of the .mem file. Delegates the allocation of data area
6591 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6592 the begining of the stack area to aslink.
6594 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6595 glue() in SDCCglue.c creates an area for it.
6597 2002-09-03 Borut Razem <borut.razem AT siol.net>
6598 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6599 sdcc/src/pic/glue.c:
6600 introduced atexit() handler for teporay files removal in case of
6601 errors, assertions, ...
6603 2002-08-29 Borut Razem <borut.razem AT siol.net>
6604 * sdcc/support/cpp2/auto-host_vc_in.h:
6605 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6606 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6607 Maybe there is a similar problem with BORLANDC? It should be checked!
6609 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6610 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6611 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6612 was not executed, and the compiler (cl) launched a warning:
6613 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6615 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6616 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6618 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6619 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6621 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6622 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6623 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6624 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6625 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6626 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6627 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6628 - added Release configuration in VS projects
6629 - review of compiler an linker options
6630 - VC .exe files are generated in bin_vc directory, not to interfere
6631 with binaries generated from other projects (cygwin, mingw, bcc ...)
6633 * sdcc/src/yacc.dsp: added
6635 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6636 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6637 and insert the version number definitions from .version
6639 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6641 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6642 added - genarate auto-host.h using auto-host_vc_in.h as template
6645 removed from CVS, generated automatically
6647 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6648 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6650 2002-08-11 Borut Razem <borut.razem AT siol.net>
6651 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6653 2002-08-10 Borut Razem <borut.razem AT siol.net>
6654 * src/SDCCmain.c (main):
6655 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6656 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6657 The consequence was that some temporary files were not removed.
6660 unification of code in functions tempfilename() and tempfile():
6661 function tempnam() is defined in Visual Studio 6.0 and .NET
6663 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6665 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6666 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6667 - removed compiler command line option /WX: Treats all warnings as errors
6668 - update a list of source files, included into the project
6670 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6671 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6672 changed project type to Generic Project so that can be correcly converted to VS.NET project
6674 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6676 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6678 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
6680 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6681 added return 0 statements after assert() to make compiler happy
6683 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6684 added newline in the def file to keep MSC compiler satisfied
6686 * sdcc/src/z80/gen.c:
6687 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6688 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6689 - solved MSC error in function aopDump()
6691 * sdcc_vc.h: define PREFIX as "\\sdcc"
6693 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
6694 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

6742 Added -p option. Allows port dependent processor to be specified.
6745 Initialized the new field char *Processor field to NULL in all ports
6748 Compiler generated registers for interrupt context saving
6749 were not getting allocated.
6751 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
6754 Fixed left shift. Will promote the left side of a left shift
6755 if a) left shifting more than size of operand or b) when assigned
6756 to something size > size of left side
6758 2002-03-14 Scott Dattalo <scott AT dattalo.com>

6866 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
6868 * sdcc/src/SDCCloop.c:
6869 Previous fix was not good. basic blocks that have "break" or "return" are
6870 not really partof a loop , but live ranges used in these blocks should
6871 be live thru the entire loop, so set partOfLoop but don't add them to
6874 2002-02-21 <johan AT FRIJA>
6876 * src/SDCCcse.c: fixed bug #514308
6878 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

6882 statement inside a loop, it was not being considered part of the loop.
6884 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
6886 2002-02-10 Karl Bongers <karl AT turbobit.com>
6889 Fixed up SDCDB debugger somewhat. Updated debugger/README
6890 with lots of comments and notes.
6892 * device/examples/test2.c:
6893 Fix bug, "red" variable not being initialized(compiler complained).
