2300 * support/regression/generate-cases.py (main): Changed from inline
2303 * doc/Makefile (install): Changed to depth first to get rid of
2304 missing directory install warning.
2306 * as/Makefile (install-doc): Made work on Mac.
2308 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
2310 * src/SDCCast.c: added an additional type flow in decorateType() of
2311 opposite direction, see feature request #860006; it's enabled at runtime
2312 by setting the environment variable SDCC_NEWTYPEFLOW
2313 * src/SDCCast.h: changed prototype of decorateType()
2314 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
2315 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
2316 'char' to 'int' can be omitted, if both operands are 'unsigned char';
2317 see feature request #877103
2318 * src/SDCCval.c: updated call of decorateType()
2319 (valBitwise): fixed bug #882876
2320 (valMinus): added promotion
2321 (valLogicAndOr): result is unsigned
2322 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
2323 * src/SDCCsymt.c (computeType),
2324 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'

2346 * src/pic/ralloc.h: applied patch from Slade Rich;
2347 added support for multiple code pages and multiple RAM banks on the
2348 PIC 14 port. The ASM files now no longer simply assume all the
2349 code / RAM are in the same page / bank. This means the linker can
2350 safely allocate code/RAM of separate ASM files to different pages/banks.
2351 * doc/sdccman.lyx: added Slade's tips
2352 * src/mcs51/peeph.def: fixed bug #880768

2394 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
2396 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
2397 loaded with the linker search paths (-L arguments) and the libraries
2398 to be linked with the current source (-l arguments). Changes
2399 currently will affect only the pic16 port.
2400 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
2401 include path the port specific paths and port specific libraries,
2402 * gplink command now contains the $3 argument,
2403 * src/pic16/device.h,
2404 * src/pic16/device.c,: structure PIC_device is made public and
2405 renamed to PIC16_device, the same for variable Pics which is renamed

2420 Documenting changes from previous commits.
2421 * configure.in (version 1.56),
2422 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
2423 when generating output files to configure the pic16 library,
2424 but now I've commented it out, since gputils aren't installed in the
2425 SF compile farm, so library won't compile
2427 * device/lib/Makefile.in (version 1.56): initially I've added in
2428 target 'all' the prerequestive 'model-pic16' so it compiled the
2429 pic16 library, but now I've commented it out for the same reasons
2431 * added targets 'model-pic16' and 'objects-pic16' to compile the
2433 * added target 'port-specific-objects-pic16' to handle the
2434 generated libraries and copy them into the build/ directory
2435 * added target 'clean-intermediate-pic16' to clean intermediate
2436 files into pic16 directory
2437 * in target 'installdirs' added line to create directory pic16 in
2438 the installation path
2440 * device/include/Makefile.in (version 1.11): in target 'install'
2441 added lines to copy all header files to installation path,
2442 * in target 'installdirs' added line create directory for pic16
2443 headers in the installation path

2458 * src/z80/main.c (_parseOptions): fixed the portmode= command line
2459 option so that it actually works. Made it specific to the z80, since
2460 the gbz80 doesn't have these kinds of I/O ports.
2462 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2464 * device/include/z180.h,

2486 Mainly changes to support compilation of the device libraries
2487 * src/pic16/device.c: stack is allocated via symbol and not
2488 via literal number. The symbol is placed in the corresponding
2489 position of the data ram
2490 * (pic16_dump_section): relocatable and absolute uninitialized
2491 data are now emitted in sorted order to reduce section naming,
2492 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
2493 weren't marked as being in the access bank,
2495 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
2497 Added portion of GNU PIC Library under the directory
2498 device/include/pic16 and device/lib/pic16. These files
2499 contain the declarations of SFRs for the PIC18Fxx2 devices.
2500 The directory is initialized via configure from toplevel.

2530 all over. Telling LaTeX to be less strict with word spacing
2531 to better keep the right margin. Changed some notes about
2532 maintainance of the ports in section 3.2.1 - is it OK like this?
2534 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

2574 * src/pic16/peeph.def: all peepholes with movff are commented out,
2575 because there is a problem in the pcode peep optimizer,
2576 * src/pic16/ralloc.c: the register allocator can now reuse local

2717 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
2719 * sdcc.spec: updated
2720 * device/include/Makefile.in: don't install CVS directories

2728 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
2730 PIC16 port related changes:
2731 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
2732 added variable stackPos,
2734 * gen.c: genCall, assignResultValue: added support for
2735 pushing/retrieving function parameters to/from stack,
2736 genFunction,genEndFunction: setup stack frame for the
2738 genAddrOf: will be changed according to bug 863624
2740 * added files genutils.c and genutils.h which contain gen*
2741 debugged and optimised functions extracted from gen.c
2743 * glue.c: added variable 'externs' which holds extern symbols,
2744 pic16emitRegularMap: is modified to properly handle relocatable
2745 symbols under the new scheme,
2746 pic16createInterruptVect: is modified
2747 pic16printPublics: is modified to emit 'global' assembler directives,
2748 added pic16_printExterns to print extern symbols,
2749 pic16glue: initializes stack/frame pointer in the beginning of
2750 the assembly output. Temporary hack, will be corrected later,
2751 because gplink yet does not support stack and SDCC does not
2752 yet support a type of crt0.o object to create the final binary.
2754 * Removed many lines that contain 8051 legacy code.
2755 * The code is finally placed under a 'code' directive.
2756 * Added port specific options.
2758 * _process_pragma: simplified since now we do not need *special*
2759 include file to define SFR registers. But a separate header
2760 will be needed. This will be developed later.
2761 * _pic16_parseOptions: added, parses port specific options:
2762 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
2763 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
2764 --preplace-udata-with=
2766 * _pic16_setDefaultOptions: modified to initialize section names,
2767 but hack is temporarly out of order since it needs improvement.
2768 * _pic16_genAssemblerPreamble: configuration words are emitted by
2769 their address instead of their name. This part is incomplete and
2770 supports only the 18Fxx2 devices. Other devices will emit an error
2771 during assembly since they do not contain the same set of config
2773 * _pic16_genIVT: is modified,
2775 * pcode.c: added definitions for some hardware registers that are needed
2777 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
2778 All PCI entries are updated. Now LFSR is supported.
2779 * Removed pic16_pciTRIS is mentioned by mdubuc in source
2780 * added pic16_newpCodeOpLit2 to support instructions with
2781 two literal arguments
2782 * pic16_pCode2str: corrected code that emits assembler instructions
2783 with two literal operands and those that have an access bit modifier
2784 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
2785 this fixes a bug which caused some labels to be lost, when an
2786 assembler directive was added, i.e. banksel,
2787 * pic16_FixRegisterBanking: improved logic that causes the insertion
2789 * InlineFunction: functions that are called once, are not any more
2790 inlined. This can be a port option in the future,
2792 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
2794 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
2795 hold the corresponding uninitialized symbols,
2796 * pic16_allocProcessorRegister: registers have explicit marked the
2798 * pic16_allocInternalRegister: registers are explicit marked as
2800 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
2801 processing list, so bit registers were lost,
2804 * ralloc.h: added field 'accessBank' and original symbol operand
2805 in register definition,
2806 * removed the field isMapped from register definition,
2808 ** Several functions have been removed from various sources:
2809 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
2810 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
2811 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
2812 pic16_assignRelocatableRegisters
2814 ** others have been introduced:
2815 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
2816 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
2818 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
2820 * support/scripts/inc2h.pl: changed definition of BIT_AT
2821 to emit 'sbit at' instead of 'bit at'. This was a request.
2823 PIC16 port related preliminary changes:
2824 * gen.c: prefixed function popRegFromString with
2825 pic16_ and all references to it corrected
2826 * pcode.c: all pic16_pc_* hardware registers prefixed
2827 with underscore (_),
2828 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
2829 * ralloc.c: newReg(): when register is REG_SFR then
2830 set address to rIdx,
2831 pic16_allocProcessorRegister(): marks register wasUsed=0
2832 pic16_writeUsedRegs(): added a call to assign processor
2833 registers via pic16_assignFixedRegisters
2835 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2837 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
2838 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
2839 variables in unused register banks. Also the SSEG is placed
2840 wherever there is enough space for it, and IDATA can be anywhere
2841 in internal RAM. For now compile using -Wl-Y[stack_size].
2842 The mem file is different for this option as well, since it
2843 makes no sense of talking about DSEG lenght.
2845 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
2847 * src/SDCClrange.c: fixed bug 869095 that caused segfault
2848 in certain cases, e.g. when ROM assignment, patch provided
2849 from Albert den Haan.

3092 * src/SDCCast.c (decorateType): disabled a transformation I added in
3093 revision 1.188 (access to fields of a structure at an absolute address);
3094 it breaks with bitfields, extern declarations, and gcse analysis.
3095 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
3096 could be assigned through a pointer, so don't complain.

3856 copied from genNearPointerSet()
3857 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
3858 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

3874 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3875 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol

3885 Z80 and MCS51 linkers complaint if a public symbol is defined
3886 in more than one library module:
3890 * as/mcs51/Makefile.in
3892 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3894 A few small changes that speed up the peephole optimizer.
3898 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3900 Try to make the peephole optimizer smarter by maintaining
3901 an association between the assembly source code and the
3902 iCodes that originated them. Put this information to use
3903 with a new peephole rule condition "notVolatile" so that
3904 the rules can be aggressive yet still safe.
3909 * src/mcs51/peeph.def
3911 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3915 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
3916 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
3917 if the left or right operand symbols have the accuse flag set.
3919 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3921 Changed the type of the result of the ! (NOT) operator to char;
3922 previously it returned the same type as the source. This allows
3923 us to eliminate all the genFloatNot functions (all of its target
3924 implementations were very buggy) since !float can use the same
3927 * src/SDCCicode.c (ast2iCode): ! returns char
3928 * src/mcs51/gen.c (genNot, genNotFloat),
3929 * src/ds390/gen.c (genNot, genNotFloat),
3930 * src/z80/gen.c (genNot, genNotFloat),
3931 * src/pic/gen.c (genNot, genNotFloat),
3932 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
3934 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
3936 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3937 1. Interrupt would not compile properly. Ensure PCLATH register is saved
3938 during interrupts. Ensure WSAVE is located at a shared bank address.
3939 2. Fixed page selection in some places
3940 3. Fixed BTFSS/C to where necessary use registers directly and not simply
3941 the registers name strings.
3942 4. Fixed "signed / unsigned compare" compiler warnings.
3943 5. The PIC port manages its own allocation of the general purpose
3944 registers, but makes no attempt to reuse them. As a result when
3945 compiling it soon runs out of general purpose registers. Some
3946 additional code was added to the files pcode.c and device.c to walk
3947 through the function call tree and rename the registers so that they
3957 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
3958 genPlus() & genMinus() when the result is the same as left or right
3960 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3964 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3966 Made bitfield a distinct type from bit so that bitfields
3967 convert as per ANSI C and bits retain their traditional
3968 boolean style behaviour. Implemented bitfield support in
3976 * src/ds390/gen.c: bit v bitfield split
3977 * src/z80/gen.c: New support for bitfields
3978 * support/regression/tests/bitfields.c: reenabled z80,
3981 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3983 Rules 246.x, 247.x relate to bitfields, the others speed up
3984 access to xdata mapped I/O devices.
3986 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
3988 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3990 Cleaned up genPackBits and genUnpackBits and added two helper
3991 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
3992 for literal assignments in genPackBits (thanks to Frieder for
3998 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4000 Fixed bug #748310 (pointer to function type mishandled when the
4001 function name is omitted). Also fixed a SIGSEGV when a function
4002 attribute (reentrant, etc) is used on a non-function or on a
4003 function but misplaced before the parameter list.
4005 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
4007 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
4008 * support/Util/SDCCerr.h,

4030 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4032 Made the constant following the "interrupt" keyword optional. If
4033 omitted, the function will not automatically be given an entry
4034 in the interrupt vector table (similar to #pragma NOIV, but
4035 less syntacticly kludgy). The interrupt number is also now
4036 range checked. Also fixed a bug in the high order bit example
4043 * support/Util/SDCCerr.c
4044 * support/Util/SDCCerr.h
4047 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
4049 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
4050 * src/SDCCicode.c (operandOperation): rewritten some ops
4051 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
4052 * src/SDCCsymt.c (computeType): literals are handled the same way as any
4054 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
4055 be re-activated by defining REDUCE_LITERALS)
4056 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
4057 unsigned, but are signed by default
4058 * src/SDCCval.c (constVal): rearranged
4059 * src/SDCCval.c (valMod): preliminary fix
4060 * src/SDCCval.c (valCastLiteral): use TYPE_* types

4102 constants are unsigned; added recognition of "u" flag for unsigned
4103 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
4104 * src/SDCCval.c (valDiv, valMod): fixed signdness
4105 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
4106 signedness of modulo, left and right shift

4512 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
4513 the regression tests I'm not brave enough to enable 245.b, 245.c
4514 * doc/sdccman.lyx: added latex preamble for hyperref package.
4515 Using pdflatex this will give you a hyperlinked pdf file with
4516 bookmarks. (prepend '%' before /usepackage if this breaks something)

4557 it can be defined with CFLAGS when running configure
4558 * src/SDCCmain.c: fixed compiling + linking with object files
4560 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

4563 added --disable-pic16-port
4564 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
4565 * src/SDCCmain.c: linkOptions is changed to set *,
4566 added if/endif conditional macros to remove options help
4567 messages from optionsTable when a port is not configured, added
4568 support for the PIc16 port in the ports table, when executing
4569 the compiler with no port specified on command line, a default
4570 port is selected with the new macro DEFAULT_PORT which is
4571 defined in port.h, in setDefaultOptions() linkOptions is removed
4572 from initialization assignment, since now it is a set,
4573 parseCmdLine uses setParseWithComma for linkOptions, in
4574 linkEdit() linkOptions are accessed with new function indexSet()
4575 which returns the i'th item of a set variable. See SDCCset.c, in
4576 linkEdit() when calling buildCmdLine(), added linkOptions as
4577 last argument. Now users can pass arguments to gplink via the
4578 -Wl option, main() uses pic16glue() to glue up pic16 programs

4590 * src/pic16/glue.c: commented out some error producing lines
4591 * src/pic16/main.c: __config directives are commented out to stop
4592 gpasm complaining and test the linkage with gplink, _linkCmd and
4593 _asmCmd changed to be more gplink and gpasm friendly
4594 * src/pic16/peeph.def: peep rule 3 is commented out, since it
4595 produced an error when parsed, peep rule 12 is added to utilize
4596 movff, but it is commented out since the pCode does not support
4597 yet a command with 2 address arguments
4599 2003-05-18 <johan AT balder>
4601 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

4628 2003-05-11 Borut Razem <borut.razem AT siol.net>
4630 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
4631 the path of bin directory, so that PATH is the only env. variable, which has to be set
4632 in case of standard installation.
4633 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

5703 Changes to aslink (All the changes are marked with 'JCF'):
5705 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
5708 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
5709 area BSEG. Also moves, if possible, the DATA area down into the internal
5710 ram so more space is available.
5712 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
5715 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
5716 not bytes. Function summary() which creates a memory usage summary
5717 file with extension .mem. Reports of overlaping stack and small stack
5718 size. If the space for the stack is less than 16 bytes aslink trows a
5721 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
5722 the 8051. Option 'y' for memory summary output file.
5724 Changes to sdcc (All the changes are marked with 'JCF'):
5726 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
5728 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
5729 overlaying area for it (uses RegBankUsed[4]).
5731 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
5732 bank zero as used by default. By default aslink locates the stack
5733 (equivalent to --stack-after-data). Pass option 'y' to aslink for
5734 the creation of the .mem file. Delegates the allocation of data area
5735 to aslink (it is not longer 0x30 by default). If --stack-loc passes
5736 the begining of the stack area to aslink.
5738 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
5739 glue() in SDCCglue.c creates an area for it.
5741 2002-09-03 Borut Razem <borut.razem AT siol.net>
5742 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
5743 sdcc/src/pic/glue.c:
5744 introduced atexit() handler for teporay files removal in case of
5745 errors, assertions, ...
5747 2002-08-29 Borut Razem <borut.razem AT siol.net>
5748 * sdcc/support/cpp2/auto-host_vc_in.h:
5749 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
5750 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
5751 Maybe there is a similar problem with BORLANDC? It should be checked!
5753 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
5754 corrected improper use of assert: the assignment to clr variable was done inside the assert.
5755 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
5756 was not executed, and the compiler (cl) launched a warning:
5757 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
5759 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
5760 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
5762 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
5763 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
5765 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5766 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
5767 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
5768 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5769 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
5770 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
5771 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
5772 - added Release configuration in VS projects
5773 - review of compiler an linker options
5774 - VC .exe files are generated in bin_vc directory, not to interfere
5775 with binaries generated from other projects (cygwin, mingw, bcc ...)
5777 * sdcc/src/yacc.dsp: added
5779 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
5780 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
5781 and insert the version number definitions from .version
5783 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
5785 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
5786 added - genarate auto-host.h using auto-host_vc_in.h as template
5789 removed from CVS, generated automatically
5791 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
5792 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
5794 2002-08-11 Borut Razem <borut.razem AT siol.net>
5795 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
5797 2002-08-10 Borut Razem <borut.razem AT siol.net>
5798 * src/SDCCmain.c (main):
5799 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
5800 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
5801 The consequence was that some temporary files were not removed.
5804 unification of code in functions tempfilename() and tempfile():
5805 function tempnam() is defined in Visual Studio 6.0 and .NET
5807 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
5809 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5810 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
5811 - removed compiler command line option /WX: Treats all warnings as errors
5812 - update a list of source files, included into the project
5814 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5815 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
5816 changed project type to Generic Project so that can be correcly converted to VS.NET project
5818 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
5820 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
5822 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
5824 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
5825 added return 0 statements after assert() to make compiler happy
5827 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
5828 added newline in the def file to keep MSC compiler satisfied
5830 * sdcc/src/z80/gen.c:
5831 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
5832 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
5833 - solved MSC error in function aopDump()
5835 * sdcc_vc.h: define PREFIX as "\\sdcc"
5837 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
5838 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

5877 2002-03-28 Johan Knol <johan AT balder>
5879 * src/SDCCval.c: fixed bug #532436
5881 2002-03-14 Scott Dattalo <scott AT dattalo.com>
5883 Added "char *Processor" field to the port structure.
5886 Added -p option. Allows port dependent processor to be specified.
5889 Initialized the new field char *Processor field to NULL in all ports
5892 Compiler generated registers for interrupt context saving
5893 were not getting allocated.
5895 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
5898 Fixed left shift. Will promote the left side of a left shift
5899 if a) left shifting more than size of operand or b) when assigned
5900 to something size > size of left side
5902 2002-03-14 Scott Dattalo <scott AT dattalo.com>
5904 tons of changes. Register allocation has been
5905 rewritten. Added customization for the various PICs. Flow

6010 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
6012 * sdcc/src/SDCCloop.c:
6013 Previous fix was not good. basic blocks that have "break" or "return" are
6014 not really partof a loop , but live ranges used in these blocks should
6015 be live thru the entire loop, so set partOfLoop but don't add them to
6018 2002-02-21 <johan AT FRIJA>
6020 * src/SDCCcse.c: fixed bug #514308
6022 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

6026 statement inside a loop, it was not being considered part of the loop.
6028 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
6030 2002-02-10 Karl Bongers <karl AT turbobit.com>
6033 Fixed up SDCDB debugger somewhat. Updated debugger/README
6034 with lots of comments and notes.
6036 * device/examples/test2.c:
6037 Fix bug, "red" variable not being initialized(compiler complained).
