151 Adding support for replacing ljmps with sjmps in jumptables
152 generated for switch statements. For now you need to set the
153 environment variable SDCC_SJMP_JUMPTABLE to enable this.

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

207 special compare&skip instructions. Initial tests fail some times
208 with variables grater than 1 byte in size, so new code is disabled,
209 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
211 * (genCast): began a fix to optimize the casting of a bit to another
212 bit, now assigning a bitfield to another bitfield will fail, sorry,

3141 * support/regression/generate-cases.py (main): Changed from inline
3144 * doc/Makefile (install): Changed to depth first to get rid of
3145 missing directory install warning.
3147 * as/Makefile (install-doc): Made work on Mac.
3149 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
3151 * src/SDCCast.c: added an additional type flow in decorateType() of
3152 opposite direction, see feature request #860006; it's enabled at runtime
3153 by setting the environment variable SDCC_NEWTYPEFLOW
3154 * src/SDCCast.h: changed prototype of decorateType()
3155 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
3156 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
3157 'char' to 'int' can be omitted, if both operands are 'unsigned char';
3158 see feature request #877103
3159 * src/SDCCval.c: updated call of decorateType()
3160 (valBitwise): fixed bug #882876
3161 (valMinus): added promotion
3162 (valLogicAndOr): result is unsigned
3163 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
3164 * src/SDCCsymt.c (computeType),
3165 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
3166 must not cause an unsigned operation
3167 * src/pic/glue (pic14emitRegularMap),
3168 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
3170 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>

3187 * src/pic/ralloc.h: applied patch from Slade Rich;
3188 added support for multiple code pages and multiple RAM banks on the
3189 PIC 14 port. The ASM files now no longer simply assume all the
3190 code / RAM are in the same page / bank. This means the linker can
3191 safely allocate code/RAM of separate ASM files to different pages/banks.
3192 * doc/sdccman.lyx: added Slade's tips
3193 * src/mcs51/peeph.def: fixed bug #880768

3205 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
3206 strtof is not part of C89 and isn't included with Mac OS X.
3208 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3210 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

3235 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3237 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3238 loaded with the linker search paths (-L arguments) and the libraries
3239 to be linked with the current source (-l arguments). Changes
3240 currently will affect only the pic16 port.
3241 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3242 include path the port specific paths and port specific libraries,
3243 * gplink command now contains the $3 argument,
3244 * src/pic16/device.h,
3245 * src/pic16/device.c,: structure PIC_device is made public and
3246 renamed to PIC16_device, the same for variable Pics which is renamed

3261 Documenting changes from previous commits.
3262 * configure.in (version 1.56),
3263 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3264 when generating output files to configure the pic16 library,
3265 but now I've commented it out, since gputils aren't installed in the
3266 SF compile farm, so library won't compile
3268 * device/lib/Makefile.in (version 1.56): initially I've added in
3269 target 'all' the prerequestive 'model-pic16' so it compiled the
3270 pic16 library, but now I've commented it out for the same reasons
3272 * added targets 'model-pic16' and 'objects-pic16' to compile the
3274 * added target 'port-specific-objects-pic16' to handle the
3275 generated libraries and copy them into the build/ directory
3276 * added target 'clean-intermediate-pic16' to clean intermediate
3277 files into pic16 directory
3278 * in target 'installdirs' added line to create directory pic16 in
3279 the installation path
3281 * device/include/Makefile.in (version 1.11): in target 'install'
3282 added lines to copy all header files to installation path,
3283 * in target 'installdirs' added line create directory for pic16
3284 headers in the installation path

3299 * src/z80/main.c (_parseOptions): fixed the portmode= command line
3300 option so that it actually works. Made it specific to the z80, since
3301 the gbz80 doesn't have these kinds of I/O ports.
3303 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3305 * device/include/z180.h,

3327 Mainly changes to support compilation of the device libraries
3328 * src/pic16/device.c: stack is allocated via symbol and not
3329 via literal number. The symbol is placed in the corresponding
3330 position of the data ram
3331 * (pic16_dump_section): relocatable and absolute uninitialized
3332 data are now emitted in sorted order to reduce section naming,
3333 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3334 weren't marked as being in the access bank,
3336 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3338 Added portion of GNU PIC Library under the directory
3339 device/include/pic16 and device/lib/pic16. These files
3340 contain the declarations of SFRs for the PIC18Fxx2 devices.
3341 The directory is initialized via configure from toplevel.
3343 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

3371 all over. Telling LaTeX to be less strict with word spacing
3372 to better keep the right margin. Changed some notes about
3373 maintainance of the ports in section 3.2.1 - is it OK like this?
3375 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

3415 * src/pic16/peeph.def: all peepholes with movff are commented out,
3416 because there is a problem in the pcode peep optimizer,
3417 * src/pic16/ralloc.c: the register allocator can now reuse local

3558 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3560 * sdcc.spec: updated
3561 * device/include/Makefile.in: don't install CVS directories

3569 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3571 PIC16 port related changes:
3572 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3573 added variable stackPos,
3575 * gen.c: genCall, assignResultValue: added support for
3576 pushing/retrieving function parameters to/from stack,
3577 genFunction,genEndFunction: setup stack frame for the
3579 genAddrOf: will be changed according to bug 863624
3581 * added files genutils.c and genutils.h which contain gen*
3582 debugged and optimised functions extracted from gen.c
3584 * glue.c: added variable 'externs' which holds extern symbols,
3585 pic16emitRegularMap: is modified to properly handle relocatable
3586 symbols under the new scheme,
3587 pic16createInterruptVect: is modified
3588 pic16printPublics: is modified to emit 'global' assembler directives,
3589 added pic16_printExterns to print extern symbols,
3590 pic16glue: initializes stack/frame pointer in the beginning of
3591 the assembly output. Temporary hack, will be corrected later,
3592 because gplink yet does not support stack and SDCC does not
3593 yet support a type of crt0.o object to create the final binary.
3595 * Removed many lines that contain 8051 legacy code.
3596 * The code is finally placed under a 'code' directive.
3597 * Added port specific options.
3599 * _process_pragma: simplified since now we do not need *special*
3600 include file to define SFR registers. But a separate header
3601 will be needed. This will be developed later.
3602 * _pic16_parseOptions: added, parses port specific options:
3603 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3604 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3605 --preplace-udata-with=
3607 * _pic16_setDefaultOptions: modified to initialize section names,
3608 but hack is temporarly out of order since it needs improvement.
3609 * _pic16_genAssemblerPreamble: configuration words are emitted by
3610 their address instead of their name. This part is incomplete and
3611 supports only the 18Fxx2 devices. Other devices will emit an error
3612 during assembly since they do not contain the same set of config
3614 * _pic16_genIVT: is modified,
3616 * pcode.c: added definitions for some hardware registers that are needed
3618 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3619 All PCI entries are updated. Now LFSR is supported.
3620 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3621 * added pic16_newpCodeOpLit2 to support instructions with
3622 two literal arguments
3623 * pic16_pCode2str: corrected code that emits assembler instructions
3624 with two literal operands and those that have an access bit modifier
3625 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3626 this fixes a bug which caused some labels to be lost, when an
3627 assembler directive was added, i.e. banksel,
3628 * pic16_FixRegisterBanking: improved logic that causes the insertion
3630 * InlineFunction: functions that are called once, are not any more
3631 inlined. This can be a port option in the future,
3633 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3635 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3636 hold the corresponding uninitialized symbols,
3637 * pic16_allocProcessorRegister: registers have explicit marked the
3639 * pic16_allocInternalRegister: registers are explicit marked as
3641 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3642 processing list, so bit registers were lost,
3645 * ralloc.h: added field 'accessBank' and original symbol operand
3646 in register definition,
3647 * removed the field isMapped from register definition,
3649 ** Several functions have been removed from various sources:
3650 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3651 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3652 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3653 pic16_assignRelocatableRegisters
3655 ** others have been introduced:
3656 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3657 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3659 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3661 * support/scripts/inc2h.pl: changed definition of BIT_AT
3662 to emit 'sbit at' instead of 'bit at'. This was a request.
3664 PIC16 port related preliminary changes:
3665 * gen.c: prefixed function popRegFromString with
3666 pic16_ and all references to it corrected
3667 * pcode.c: all pic16_pc_* hardware registers prefixed
3668 with underscore (_),
3669 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3670 * ralloc.c: newReg(): when register is REG_SFR then
3671 set address to rIdx,
3672 pic16_allocProcessorRegister(): marks register wasUsed=0
3673 pic16_writeUsedRegs(): added a call to assign processor
3674 registers via pic16_assignFixedRegisters
3676 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3678 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3679 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3680 variables in unused register banks. Also the SSEG is placed
3681 wherever there is enough space for it, and IDATA can be anywhere
3682 in internal RAM. For now compile using -Wl-Y[stack_size].
3683 The mem file is different for this option as well, since it
3684 makes no sense of talking about DSEG lenght.
3686 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3688 * src/SDCClrange.c: fixed bug 869095 that caused segfault

3933 * src/SDCCast.c (decorateType): disabled a transformation I added in
3934 revision 1.188 (access to fields of a structure at an absolute address);
3935 it breaks with bitfields, extern declarations, and gcse analysis.
3936 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
3937 could be assigned through a pointer, so don't complain.

4694 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
4695 fetching of the pointer
4696 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
4697 copied from genNearPointerSet()
4698 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
4699 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

4713 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
4715 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4716 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4717 type for bits was changed. It resulted in bit variables becoming
4718 global, which is not permitted in PIC 14 assembly output.
4720 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4722 * doc/sdccman.lyx: various additions and updates. Rearranged sections

4735 A few small changes that speed up the peephole optimizer.
4739 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4741 Try to make the peephole optimizer smarter by maintaining
4742 an association between the assembly source code and the
4743 iCodes that originated them. Put this information to use
4744 with a new peephole rule condition "notVolatile" so that
4745 the rules can be aggressive yet still safe.
4750 * src/mcs51/peeph.def
4752 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4756 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4757 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4758 if the left or right operand symbols have the accuse flag set.
4760 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4762 Changed the type of the result of the ! (NOT) operator to char;
4763 previously it returned the same type as the source. This allows
4764 us to eliminate all the genFloatNot functions (all of its target
4765 implementations were very buggy) since !float can use the same
4768 * src/SDCCicode.c (ast2iCode): ! returns char

4770 * src/ds390/gen.c (genNot, genNotFloat),
4771 * src/z80/gen.c (genNot, genNotFloat),
4772 * src/pic/gen.c (genNot, genNotFloat),

4775 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
4777 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4778 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4779 during interrupts. Ensure WSAVE is located at a shared bank address.
4780 2. Fixed page selection in some places
4781 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4782 the registers name strings.
4783 4. Fixed "signed / unsigned compare" compiler warnings.
4784 5. The PIC port manages its own allocation of the general purpose
4785 registers, but makes no attempt to reuse them. As a result when
4786 compiling it soon runs out of general purpose registers. Some
4787 additional code was added to the files pcode.c and device.c to walk
4788 through the function call tree and rename the registers so that they
4798 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
4799 genPlus() & genMinus() when the result is the same as left or right

4805 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4807 Made bitfield a distinct type from bit so that bitfields
4808 convert as per ANSI C and bits retain their traditional
4809 boolean style behaviour. Implemented bitfield support in
4817 * src/ds390/gen.c: bit v bitfield split
4818 * src/z80/gen.c: New support for bitfields
4819 * support/regression/tests/bitfields.c: reenabled z80,
4822 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4824 Rules 246.x, 247.x relate to bitfields, the others speed up
4825 access to xdata mapped I/O devices.
4827 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4829 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4831 Cleaned up genPackBits and genUnpackBits and added two helper
4832 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4833 for literal assignments in genPackBits (thanks to Frieder for
4839 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4841 Fixed bug #748310 (pointer to function type mishandled when the
4842 function name is omitted). Also fixed a SIGSEGV when a function
4843 attribute (reentrant, etc) is used on a non-function or on a
4844 function but misplaced before the parameter list.
4846 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
4848 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

4871 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4873 Made the constant following the "interrupt" keyword optional. If
4874 omitted, the function will not automatically be given an entry
4875 in the interrupt vector table (similar to #pragma NOIV, but
4876 less syntacticly kludgy). The interrupt number is also now
4877 range checked. Also fixed a bug in the high order bit example

4891 * src/SDCCicode.c (operandOperation): rewritten some ops
4892 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
4893 * src/SDCCsymt.c (computeType): literals are handled the same way as any
4895 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
4896 be re-activated by defining REDUCE_LITERALS)
4897 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
4898 unsigned, but are signed by default
4899 * src/SDCCval.c (constVal): rearranged
4900 * src/SDCCval.c (valMod): preliminary fix
4901 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5353 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
5354 the regression tests I'm not brave enough to enable 245.b, 245.c
5355 * doc/sdccman.lyx: added latex preamble for hyperref package.
5356 Using pdflatex this will give you a hyperlinked pdf file with
5357 bookmarks. (prepend '%' before /usepackage if this breaks something)

5395 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
5397 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
5398 it can be defined with CFLAGS when running configure
5399 * src/SDCCmain.c: fixed compiling + linking with object files
5401 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

5404 added --disable-pic16-port
5405 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
5406 * src/SDCCmain.c: linkOptions is changed to set *,
5407 added if/endif conditional macros to remove options help
5408 messages from optionsTable when a port is not configured, added
5409 support for the PIc16 port in the ports table, when executing
5410 the compiler with no port specified on command line, a default
5411 port is selected with the new macro DEFAULT_PORT which is
5412 defined in port.h, in setDefaultOptions() linkOptions is removed
5413 from initialization assignment, since now it is a set,
5414 parseCmdLine uses setParseWithComma for linkOptions, in
5415 linkEdit() linkOptions are accessed with new function indexSet()
5416 which returns the i'th item of a set variable. See SDCCset.c, in
5417 linkEdit() when calling buildCmdLine(), added linkOptions as
5418 last argument. Now users can pass arguments to gplink via the
5419 -Wl option, main() uses pic16glue() to glue up pic16 programs
5420 * src/SDCCpeeph.c: various changes to support pic16

5431 * src/pic16/glue.c: commented out some error producing lines
5432 * src/pic16/main.c: __config directives are commented out to stop
5433 gpasm complaining and test the linkage with gplink, _linkCmd and
5434 _asmCmd changed to be more gplink and gpasm friendly
5435 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5436 produced an error when parsed, peep rule 12 is added to utilize
5437 movff, but it is commented out since the pCode does not support
5438 yet a command with 2 address arguments
5440 2003-05-18 <johan AT balder>
5442 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5469 2003-05-11 Borut Razem <borut.razem AT siol.net>
5471 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5472 the path of bin directory, so that PATH is the only env. variable, which has to be set
5473 in case of standard installation.
5474 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

6556 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6557 not bytes. Function summary() which creates a memory usage summary
6558 file with extension .mem. Reports of overlaping stack and small stack
6559 size. If the space for the stack is less than 16 bytes aslink trows a
6562 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6563 the 8051. Option 'y' for memory summary output file.
6565 Changes to sdcc (All the changes are marked with 'JCF'):
6567 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6569 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6570 overlaying area for it (uses RegBankUsed[4]).
6572 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6573 bank zero as used by default. By default aslink locates the stack
6574 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6575 the creation of the .mem file. Delegates the allocation of data area
6576 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6577 the begining of the stack area to aslink.
6579 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6580 glue() in SDCCglue.c creates an area for it.
6582 2002-09-03 Borut Razem <borut.razem AT siol.net>
6583 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6584 sdcc/src/pic/glue.c:
6585 introduced atexit() handler for teporay files removal in case of
6586 errors, assertions, ...
6588 2002-08-29 Borut Razem <borut.razem AT siol.net>
6589 * sdcc/support/cpp2/auto-host_vc_in.h:
6590 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6591 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6592 Maybe there is a similar problem with BORLANDC? It should be checked!
6594 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6595 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6596 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6597 was not executed, and the compiler (cl) launched a warning:
6598 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6600 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6601 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6603 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6604 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6606 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6607 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6608 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6609 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6610 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6611 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6612 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6613 - added Release configuration in VS projects
6614 - review of compiler an linker options
6615 - VC .exe files are generated in bin_vc directory, not to interfere
6616 with binaries generated from other projects (cygwin, mingw, bcc ...)
6618 * sdcc/src/yacc.dsp: added
6620 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6621 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6622 and insert the version number definitions from .version
6624 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6626 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6627 added - genarate auto-host.h using auto-host_vc_in.h as template
6630 removed from CVS, generated automatically
6632 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6633 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6635 2002-08-11 Borut Razem <borut.razem AT siol.net>
6636 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6638 2002-08-10 Borut Razem <borut.razem AT siol.net>
6639 * src/SDCCmain.c (main):
6640 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6641 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6642 The consequence was that some temporary files were not removed.
6645 unification of code in functions tempfilename() and tempfile():
6646 function tempnam() is defined in Visual Studio 6.0 and .NET
6648 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6650 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6651 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6652 - removed compiler command line option /WX: Treats all warnings as errors
6653 - update a list of source files, included into the project
6655 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6656 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6657 changed project type to Generic Project so that can be correcly converted to VS.NET project
6659 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6661 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6663 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
6665 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6666 added return 0 statements after assert() to make compiler happy
6668 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6669 added newline in the def file to keep MSC compiler satisfied
6671 * sdcc/src/z80/gen.c:
6672 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6673 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6674 - solved MSC error in function aopDump()
6676 * sdcc_vc.h: define PREFIX as "\\sdcc"
6678 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
6679 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

6727 Added -p option. Allows port dependent processor to be specified.
6730 Initialized the new field char *Processor field to NULL in all ports
6733 Compiler generated registers for interrupt context saving
6734 were not getting allocated.
6736 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
6739 Fixed left shift. Will promote the left side of a left shift
6740 if a) left shifting more than size of operand or b) when assigned
6741 to something size > size of left side
6743 2002-03-14 Scott Dattalo <scott AT dattalo.com>

6851 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
6853 * sdcc/src/SDCCloop.c:
6854 Previous fix was not good. basic blocks that have "break" or "return" are
6855 not really partof a loop , but live ranges used in these blocks should
6856 be live thru the entire loop, so set partOfLoop but don't add them to
6859 2002-02-21 <johan AT FRIJA>
6861 * src/SDCCcse.c: fixed bug #514308
6863 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

6867 statement inside a loop, it was not being considered part of the loop.
6869 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
6871 2002-02-10 Karl Bongers <karl AT turbobit.com>
