2294 by setting the environment variable SDCC_NEWTYPEFLOW
2295 * src/SDCCast.h: changed prototype of decorateType()
2296 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
2297 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
2298 'char' to 'int' can be omitted, if both operands are 'unsigned char';
2299 see feature request #877103
2300 * src/SDCCval.c: updated call of decorateType()
2301 (valBitwise): fixed bug #882876
2302 (valMinus): added promotion
2303 (valLogicAndOr): result is unsigned
2304 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
2305 * src/SDCCsymt.c (computeType),
2306 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
2307 must not cause an unsigned operation
2308 * src/pic/glue (pic14emitRegularMap),
2309 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
2311 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>

2326 * src/pic/pcoderegs.c,
2328 * src/pic/ralloc.h: applied patch from Slade Rich;
2329 added support for multiple code pages and multiple RAM banks on the
2330 PIC 14 port. The ASM files now no longer simply assume all the
2331 code / RAM are in the same page / bank. This means the linker can
2332 safely allocate code/RAM of separate ASM files to different pages/banks.
2333 * doc/sdccman.lyx: added Slade's tips
2334 * src/mcs51/peeph.def: fixed bug #880768

2343 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
2346 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
2347 strtof is not part of C89 and isn't included with Mac OS X.
2349 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2351 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

2376 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
2378 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
2379 loaded with the linker search paths (-L arguments) and the libraries
2380 to be linked with the current source (-l arguments). Changes
2381 currently will affect only the pic16 port.
2382 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
2383 include path the port specific paths and port specific libraries,
2384 * gplink command now contains the $3 argument,
2385 * src/pic16/device.h,
2386 * src/pic16/device.c,: structure PIC_device is made public and
2387 renamed to PIC16_device, the same for variable Pics which is renamed

2400 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
2402 Documenting changes from previous commits.
2403 * configure.in (version 1.56),
2404 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
2405 when generating output files to configure the pic16 library,
2406 but now I've commented it out, since gputils aren't installed in the
2407 SF compile farm, so library won't compile
2409 * device/lib/Makefile.in (version 1.56): initially I've added in
2410 target 'all' the prerequestive 'model-pic16' so it compiled the
2411 pic16 library, but now I've commented it out for the same reasons
2413 * added targets 'model-pic16' and 'objects-pic16' to compile the
2415 * added target 'port-specific-objects-pic16' to handle the
2416 generated libraries and copy them into the build/ directory
2417 * added target 'clean-intermediate-pic16' to clean intermediate
2418 files into pic16 directory
2419 * in target 'installdirs' added line to create directory pic16 in
2420 the installation path
2422 * device/include/Makefile.in (version 1.11): in target 'install'
2423 added lines to copy all header files to installation path,
2424 * in target 'installdirs' added line create directory for pic16
2425 headers in the installation path

2440 * src/z80/main.c (_parseOptions): fixed the portmode= command line
2441 option so that it actually works. Made it specific to the z80, since
2442 the gbz80 doesn't have these kinds of I/O ports.
2444 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2446 * device/include/z180.h,

2468 Mainly changes to support compilation of the device libraries
2469 * src/pic16/device.c: stack is allocated via symbol and not
2470 via literal number. The symbol is placed in the corresponding
2471 position of the data ram
2472 * (pic16_dump_section): relocatable and absolute uninitialized
2473 data are now emitted in sorted order to reduce section naming,
2474 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
2475 weren't marked as being in the access bank,
2477 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
2479 Added portion of GNU PIC Library under the directory
2480 device/include/pic16 and device/lib/pic16. These files
2481 contain the declarations of SFRs for the PIC18Fxx2 devices.
2482 The directory is initialized via configure from toplevel.
2484 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
2486 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

2512 all over. Telling LaTeX to be less strict with word spacing
2513 to better keep the right margin. Changed some notes about
2514 maintainance of the ports in section 3.2.1 - is it OK like this?
2516 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

2554 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
2556 * src/pic16/peeph.def: all peepholes with movff are commented out,
2557 because there is a problem in the pcode peep optimizer,
2558 * src/pic16/ralloc.c: the register allocator can now reuse local

2699 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
2701 * sdcc.spec: updated
2702 * device/include/Makefile.in: don't install CVS directories

2710 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
2712 PIC16 port related changes:
2713 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
2714 added variable stackPos,
2716 * gen.c: genCall, assignResultValue: added support for
2717 pushing/retrieving function parameters to/from stack,
2718 genFunction,genEndFunction: setup stack frame for the
2720 genAddrOf: will be changed according to bug 863624
2722 * added files genutils.c and genutils.h which contain gen*
2723 debugged and optimised functions extracted from gen.c
2725 * glue.c: added variable 'externs' which holds extern symbols,
2726 pic16emitRegularMap: is modified to properly handle relocatable
2727 symbols under the new scheme,
2728 pic16createInterruptVect: is modified
2729 pic16printPublics: is modified to emit 'global' assembler directives,
2730 added pic16_printExterns to print extern symbols,
2731 pic16glue: initializes stack/frame pointer in the beginning of
2732 the assembly output. Temporary hack, will be corrected later,
2733 because gplink yet does not support stack and SDCC does not
2734 yet support a type of crt0.o object to create the final binary.
2736 * Removed many lines that contain 8051 legacy code.
2737 * The code is finally placed under a 'code' directive.
2738 * Added port specific options.
2740 * _process_pragma: simplified since now we do not need *special*
2741 include file to define SFR registers. But a separate header
2742 will be needed. This will be developed later.
2743 * _pic16_parseOptions: added, parses port specific options:
2744 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
2745 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
2746 --preplace-udata-with=
2748 * _pic16_setDefaultOptions: modified to initialize section names,
2749 but hack is temporarly out of order since it needs improvement.
2750 * _pic16_genAssemblerPreamble: configuration words are emitted by
2751 their address instead of their name. This part is incomplete and
2752 supports only the 18Fxx2 devices. Other devices will emit an error
2753 during assembly since they do not contain the same set of config
2755 * _pic16_genIVT: is modified,
2757 * pcode.c: added definitions for some hardware registers that are needed
2759 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
2760 All PCI entries are updated. Now LFSR is supported.
2761 * Removed pic16_pciTRIS is mentioned by mdubuc in source
2762 * added pic16_newpCodeOpLit2 to support instructions with
2763 two literal arguments
2764 * pic16_pCode2str: corrected code that emits assembler instructions
2765 with two literal operands and those that have an access bit modifier
2766 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
2767 this fixes a bug which caused some labels to be lost, when an
2768 assembler directive was added, i.e. banksel,
2769 * pic16_FixRegisterBanking: improved logic that causes the insertion
2771 * InlineFunction: functions that are called once, are not any more
2772 inlined. This can be a port option in the future,
2774 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
2776 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
2777 hold the corresponding uninitialized symbols,
2778 * pic16_allocProcessorRegister: registers have explicit marked the
2780 * pic16_allocInternalRegister: registers are explicit marked as
2782 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
2783 processing list, so bit registers were lost,
2786 * ralloc.h: added field 'accessBank' and original symbol operand
2787 in register definition,
2788 * removed the field isMapped from register definition,
2790 ** Several functions have been removed from various sources:
2791 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
2792 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
2793 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
2794 pic16_assignRelocatableRegisters
2796 ** others have been introduced:
2797 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
2798 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
2800 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
2802 * support/scripts/inc2h.pl: changed definition of BIT_AT
2803 to emit 'sbit at' instead of 'bit at'. This was a request.
2805 PIC16 port related preliminary changes:
2806 * gen.c: prefixed function popRegFromString with
2807 pic16_ and all references to it corrected
2808 * pcode.c: all pic16_pc_* hardware registers prefixed
2809 with underscore (_),
2810 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
2811 * ralloc.c: newReg(): when register is REG_SFR then
2812 set address to rIdx,
2813 pic16_allocProcessorRegister(): marks register wasUsed=0
2814 pic16_writeUsedRegs(): added a call to assign processor
2815 registers via pic16_assignFixedRegisters
2817 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2819 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
2820 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
2821 variables in unused register banks. Also the SSEG is placed
2822 wherever there is enough space for it, and IDATA can be anywhere
2823 in internal RAM. For now compile using -Wl-Y[stack_size].
2824 The mem file is different for this option as well, since it
2825 makes no sense of talking about DSEG lenght.
2827 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
2829 * src/SDCClrange.c: fixed bug 869095 that caused segfault

3076 it breaks with bitfields, extern declarations, and gcse analysis.
3077 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
3078 could be assigned through a pointer, so don't complain.

3822 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
3823 iCode properly now. Use getSize instead of nRegs since a & b
3824 aren't part of the nRegs tally.
3826 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
3828 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

3834 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
3835 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
3836 fetching of the pointer
3837 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
3838 copied from genNearPointerSet()
3839 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
3840 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
3841 If they pop r0/r1 they must be called in the opposite order than aopOp().
3842 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
3843 (resp. --stack-auto), prepared for --xstack

3854 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
3856 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3857 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
3858 type for bits was changed. It resulted in bit variables becoming
3859 global, which is not permitted in PIC 14 assembly output.
3861 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3863 * doc/sdccman.lyx: various additions and updates. Rearranged sections

3876 A few small changes that speed up the peephole optimizer.
3880 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3882 Try to make the peephole optimizer smarter by maintaining
3883 an association between the assembly source code and the
3884 iCodes that originated them. Put this information to use
3885 with a new peephole rule condition "notVolatile" so that
3886 the rules can be aggressive yet still safe.
3891 * src/mcs51/peeph.def
3893 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3897 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
3898 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
3899 if the left or right operand symbols have the accuse flag set.
3901 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3903 Changed the type of the result of the ! (NOT) operator to char;
3904 previously it returned the same type as the source. This allows
3905 us to eliminate all the genFloatNot functions (all of its target
3906 implementations were very buggy) since !float can use the same
3909 * src/SDCCicode.c (ast2iCode): ! returns char
3910 * src/mcs51/gen.c (genNot, genNotFloat),
3911 * src/ds390/gen.c (genNot, genNotFloat),
3912 * src/z80/gen.c (genNot, genNotFloat),
3913 * src/pic/gen.c (genNot, genNotFloat),
3914 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
3916 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
3918 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3919 1. Interrupt would not compile properly. Ensure PCLATH register is saved
3920 during interrupts. Ensure WSAVE is located at a shared bank address.
3921 2. Fixed page selection in some places
3922 3. Fixed BTFSS/C to where necessary use registers directly and not simply
3923 the registers name strings.
3924 4. Fixed "signed / unsigned compare" compiler warnings.
3925 5. The PIC port manages its own allocation of the general purpose
3926 registers, but makes no attempt to reuse them. As a result when
3927 compiling it soon runs out of general purpose registers. Some
3928 additional code was added to the files pcode.c and device.c to walk
3929 through the function call tree and rename the registers so that they
3939 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
3940 genPlus() & genMinus() when the result is the same as left or right

3946 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3948 Made bitfield a distinct type from bit so that bitfields
3949 convert as per ANSI C and bits retain their traditional
3950 boolean style behaviour. Implemented bitfield support in
3958 * src/ds390/gen.c: bit v bitfield split
3959 * src/z80/gen.c: New support for bitfields
3960 * support/regression/tests/bitfields.c: reenabled z80,
3963 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3965 Rules 246.x, 247.x relate to bitfields, the others speed up
3966 access to xdata mapped I/O devices.
3968 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
3970 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3972 Cleaned up genPackBits and genUnpackBits and added two helper
3973 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
3974 for literal assignments in genPackBits (thanks to Frieder for
3980 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3982 Fixed bug #748310 (pointer to function type mishandled when the
3983 function name is omitted). Also fixed a SIGSEGV when a function
3984 attribute (reentrant, etc) is used on a non-function or on a
3985 function but misplaced before the parameter list.
3987 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
3989 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

4012 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4014 Made the constant following the "interrupt" keyword optional. If
4015 omitted, the function will not automatically be given an entry
4016 in the interrupt vector table (similar to #pragma NOIV, but
4017 less syntacticly kludgy). The interrupt number is also now
4018 range checked. Also fixed a bug in the high order bit example
4025 * support/Util/SDCCerr.c
4026 * support/Util/SDCCerr.h
4029 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

4032 * src/SDCCicode.c (operandOperation): rewritten some ops
4033 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
4034 * src/SDCCsymt.c (computeType): literals are handled the same way as any
4036 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
4037 be re-activated by defining REDUCE_LITERALS)
4038 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
4039 unsigned, but are signed by default
4040 * src/SDCCval.c (constVal): rearranged
4041 * src/SDCCval.c (valMod): preliminary fix
4042 * src/SDCCval.c (valCastLiteral): use TYPE_* types

4494 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
4495 the regression tests I'm not brave enough to enable 245.b, 245.c
4496 * doc/sdccman.lyx: added latex preamble for hyperref package.
4497 Using pdflatex this will give you a hyperlinked pdf file with
4498 bookmarks. (prepend '%' before /usepackage if this breaks something)

4539 it can be defined with CFLAGS when running configure
4540 * src/SDCCmain.c: fixed compiling + linking with object files
4542 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

4545 added --disable-pic16-port
4546 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
4547 * src/SDCCmain.c: linkOptions is changed to set *,
4548 added if/endif conditional macros to remove options help
4549 messages from optionsTable when a port is not configured, added
4550 support for the PIc16 port in the ports table, when executing
4551 the compiler with no port specified on command line, a default
4552 port is selected with the new macro DEFAULT_PORT which is
4553 defined in port.h, in setDefaultOptions() linkOptions is removed
4554 from initialization assignment, since now it is a set,
4555 parseCmdLine uses setParseWithComma for linkOptions, in
4556 linkEdit() linkOptions are accessed with new function indexSet()
4557 which returns the i'th item of a set variable. See SDCCset.c, in
4558 linkEdit() when calling buildCmdLine(), added linkOptions as
4559 last argument. Now users can pass arguments to gplink via the
4560 -Wl option, main() uses pic16glue() to glue up pic16 programs

4572 * src/pic16/glue.c: commented out some error producing lines
4573 * src/pic16/main.c: __config directives are commented out to stop
4574 gpasm complaining and test the linkage with gplink, _linkCmd and
4575 _asmCmd changed to be more gplink and gpasm friendly
4576 * src/pic16/peeph.def: peep rule 3 is commented out, since it
4577 produced an error when parsed, peep rule 12 is added to utilize
4578 movff, but it is commented out since the pCode does not support
4579 yet a command with 2 address arguments
4581 2003-05-18 <johan AT balder>
4583 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

4610 2003-05-11 Borut Razem <borut.razem AT siol.net>
4612 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
4613 the path of bin directory, so that PATH is the only env. variable, which has to be set
4614 in case of standard installation.

5708 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
5710 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
5711 overlaying area for it (uses RegBankUsed[4]).
5713 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
5714 bank zero as used by default. By default aslink locates the stack
5715 (equivalent to --stack-after-data). Pass option 'y' to aslink for
5716 the creation of the .mem file. Delegates the allocation of data area
5717 to aslink (it is not longer 0x30 by default). If --stack-loc passes
5718 the begining of the stack area to aslink.
5720 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
5721 glue() in SDCCglue.c creates an area for it.
5723 2002-09-03 Borut Razem <borut.razem AT siol.net>
5724 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
5725 sdcc/src/pic/glue.c:
5726 introduced atexit() handler for teporay files removal in case of
5727 errors, assertions, ...
5729 2002-08-29 Borut Razem <borut.razem AT siol.net>
5730 * sdcc/support/cpp2/auto-host_vc_in.h:
5731 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
5732 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
5733 Maybe there is a similar problem with BORLANDC? It should be checked!
5735 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
5736 corrected improper use of assert: the assignment to clr variable was done inside the assert.
5737 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
5738 was not executed, and the compiler (cl) launched a warning:
5739 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
5741 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
5742 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
5744 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
5745 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
5747 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5748 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
5749 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
5750 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5751 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
5752 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
5753 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
5754 - added Release configuration in VS projects
5755 - review of compiler an linker options
5756 - VC .exe files are generated in bin_vc directory, not to interfere
5757 with binaries generated from other projects (cygwin, mingw, bcc ...)
5759 * sdcc/src/yacc.dsp: added
5761 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
5762 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
5763 and insert the version number definitions from .version
5765 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
5767 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
5768 added - genarate auto-host.h using auto-host_vc_in.h as template
5771 removed from CVS, generated automatically
5773 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
5774 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
5776 2002-08-11 Borut Razem <borut.razem AT siol.net>
5777 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
5779 2002-08-10 Borut Razem <borut.razem AT siol.net>
5780 * src/SDCCmain.c (main):
5781 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
5782 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
5783 The consequence was that some temporary files were not removed.
5786 unification of code in functions tempfilename() and tempfile():
5787 function tempnam() is defined in Visual Studio 6.0 and .NET
5789 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
5791 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5792 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
5793 - removed compiler command line option /WX: Treats all warnings as errors
5794 - update a list of source files, included into the project
5796 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5797 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
5798 changed project type to Generic Project so that can be correcly converted to VS.NET project
5800 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
5802 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
5804 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
5806 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
5807 added return 0 statements after assert() to make compiler happy
5809 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
5810 added newline in the def file to keep MSC compiler satisfied
5812 * sdcc/src/z80/gen.c:
5813 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
5814 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
5815 - solved MSC error in function aopDump()
5817 * sdcc_vc.h: define PREFIX as "\\sdcc"
5819 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
5820 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

5868 Added -p option. Allows port dependent processor to be specified.
5871 Initialized the new field char *Processor field to NULL in all ports
5874 Compiler generated registers for interrupt context saving
5875 were not getting allocated.
5877 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
5880 Fixed left shift. Will promote the left side of a left shift
5881 if a) left shifting more than size of operand or b) when assigned
5882 to something size > size of left side
5884 2002-03-14 Scott Dattalo <scott AT dattalo.com>
5886 tons of changes. Register allocation has been

5992 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
5994 * sdcc/src/SDCCloop.c:
5995 Previous fix was not good. basic blocks that have "break" or "return" are
5996 not really partof a loop , but live ranges used in these blocks should
5997 be live thru the entire loop, so set partOfLoop but don't add them to
6000 2002-02-21 <johan AT FRIJA>
6002 * src/SDCCcse.c: fixed bug #514308
6004 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

6010 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
6012 2002-02-10 Karl Bongers <karl AT turbobit.com>
6015 Fixed up SDCDB debugger somewhat. Updated debugger/README
6016 with lots of comments and notes.
6018 * device/examples/test2.c:
