2297 * as/Makefile (install-doc): Made work on Mac.
2299 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
2301 * src/SDCCast.c: added an additional type flow in decorateType() of
2302 opposite direction, see feature request #860006; it's enabled at runtime
2303 by setting the environment variable SDCC_NEWTYPEFLOW
2304 * src/SDCCast.h: changed prototype of decorateType()
2305 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
2306 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
2307 'char' to 'int' can be omitted, if both operands are 'unsigned char';
2308 see feature request #877103
2309 * src/SDCCval.c: updated call of decorateType()
2310 (valBitwise): fixed bug #882876
2311 (valMinus): added promotion
2312 (valLogicAndOr): result is unsigned
2313 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
2314 * src/SDCCsymt.c (computeType),
2315 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
2316 must not cause an unsigned operation
2317 * src/pic/glue (pic14emitRegularMap),
2318 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
2320 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>

2337 * src/pic/ralloc.h: applied patch from Slade Rich;
2338 added support for multiple code pages and multiple RAM banks on the
2339 PIC 14 port. The ASM files now no longer simply assume all the
2340 code / RAM are in the same page / bank. This means the linker can
2341 safely allocate code/RAM of separate ASM files to different pages/banks.
2342 * doc/sdccman.lyx: added Slade's tips
2343 * src/mcs51/peeph.def: fixed bug #880768

2352 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
2355 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
2356 strtof is not part of C89 and isn't included with Mac OS X.
2358 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2360 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

2382 * src/ds390/gen.c (aopOp3): fixed the assignment of different dptrs to
2385 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
2387 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
2388 loaded with the linker search paths (-L arguments) and the libraries
2389 to be linked with the current source (-l arguments). Changes
2390 currently will affect only the pic16 port.
2391 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
2392 include path the port specific paths and port specific libraries,
2393 * gplink command now contains the $3 argument,
2394 * src/pic16/device.h,
2395 * src/pic16/device.c,: structure PIC_device is made public and
2396 renamed to PIC16_device, the same for variable Pics which is renamed

2411 Documenting changes from previous commits.
2412 * configure.in (version 1.56),
2413 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
2414 when generating output files to configure the pic16 library,
2415 but now I've commented it out, since gputils aren't installed in the
2416 SF compile farm, so library won't compile
2418 * device/lib/Makefile.in (version 1.56): initially I've added in
2419 target 'all' the prerequestive 'model-pic16' so it compiled the
2420 pic16 library, but now I've commented it out for the same reasons
2422 * added targets 'model-pic16' and 'objects-pic16' to compile the
2424 * added target 'port-specific-objects-pic16' to handle the
2425 generated libraries and copy them into the build/ directory
2426 * added target 'clean-intermediate-pic16' to clean intermediate
2427 files into pic16 directory
2428 * in target 'installdirs' added line to create directory pic16 in
2429 the installation path
2431 * device/include/Makefile.in (version 1.11): in target 'install'
2432 added lines to copy all header files to installation path,
2433 * in target 'installdirs' added line create directory for pic16
2434 headers in the installation path

2449 * src/z80/main.c (_parseOptions): fixed the portmode= command line
2450 option so that it actually works. Made it specific to the z80, since
2451 the gbz80 doesn't have these kinds of I/O ports.
2453 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2455 * device/include/z180.h,

2477 Mainly changes to support compilation of the device libraries
2478 * src/pic16/device.c: stack is allocated via symbol and not
2479 via literal number. The symbol is placed in the corresponding
2480 position of the data ram
2481 * (pic16_dump_section): relocatable and absolute uninitialized
2482 data are now emitted in sorted order to reduce section naming,
2483 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
2484 weren't marked as being in the access bank,
2486 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
2488 Added portion of GNU PIC Library under the directory
2489 device/include/pic16 and device/lib/pic16. These files
2490 contain the declarations of SFRs for the PIC18Fxx2 devices.
2491 The directory is initialized via configure from toplevel.
2493 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

2521 all over. Telling LaTeX to be less strict with word spacing
2522 to better keep the right margin. Changed some notes about
2523 maintainance of the ports in section 3.2.1 - is it OK like this?
2525 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

2563 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
2565 * src/pic16/peeph.def: all peepholes with movff are commented out,
2566 because there is a problem in the pcode peep optimizer,
2567 * src/pic16/ralloc.c: the register allocator can now reuse local

2708 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
2710 * sdcc.spec: updated
2711 * device/include/Makefile.in: don't install CVS directories

2719 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
2721 PIC16 port related changes:
2722 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
2723 added variable stackPos,
2725 * gen.c: genCall, assignResultValue: added support for
2726 pushing/retrieving function parameters to/from stack,
2727 genFunction,genEndFunction: setup stack frame for the
2729 genAddrOf: will be changed according to bug 863624
2731 * added files genutils.c and genutils.h which contain gen*
2732 debugged and optimised functions extracted from gen.c
2734 * glue.c: added variable 'externs' which holds extern symbols,
2735 pic16emitRegularMap: is modified to properly handle relocatable
2736 symbols under the new scheme,
2737 pic16createInterruptVect: is modified
2738 pic16printPublics: is modified to emit 'global' assembler directives,
2739 added pic16_printExterns to print extern symbols,
2740 pic16glue: initializes stack/frame pointer in the beginning of
2741 the assembly output. Temporary hack, will be corrected later,
2742 because gplink yet does not support stack and SDCC does not
2743 yet support a type of crt0.o object to create the final binary.
2745 * Removed many lines that contain 8051 legacy code.
2746 * The code is finally placed under a 'code' directive.
2747 * Added port specific options.
2749 * _process_pragma: simplified since now we do not need *special*
2750 include file to define SFR registers. But a separate header
2751 will be needed. This will be developed later.
2752 * _pic16_parseOptions: added, parses port specific options:
2753 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
2754 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
2755 --preplace-udata-with=
2757 * _pic16_setDefaultOptions: modified to initialize section names,
2758 but hack is temporarly out of order since it needs improvement.
2759 * _pic16_genAssemblerPreamble: configuration words are emitted by
2760 their address instead of their name. This part is incomplete and
2761 supports only the 18Fxx2 devices. Other devices will emit an error
2762 during assembly since they do not contain the same set of config
2764 * _pic16_genIVT: is modified,
2766 * pcode.c: added definitions for some hardware registers that are needed
2768 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
2769 All PCI entries are updated. Now LFSR is supported.
2770 * Removed pic16_pciTRIS is mentioned by mdubuc in source
2771 * added pic16_newpCodeOpLit2 to support instructions with
2772 two literal arguments
2773 * pic16_pCode2str: corrected code that emits assembler instructions
2774 with two literal operands and those that have an access bit modifier
2775 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
2776 this fixes a bug which caused some labels to be lost, when an
2777 assembler directive was added, i.e. banksel,
2778 * pic16_FixRegisterBanking: improved logic that causes the insertion
2780 * InlineFunction: functions that are called once, are not any more
2781 inlined. This can be a port option in the future,
2783 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
2785 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
2786 hold the corresponding uninitialized symbols,
2787 * pic16_allocProcessorRegister: registers have explicit marked the
2789 * pic16_allocInternalRegister: registers are explicit marked as
2791 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
2792 processing list, so bit registers were lost,
2795 * ralloc.h: added field 'accessBank' and original symbol operand
2796 in register definition,
2797 * removed the field isMapped from register definition,
2799 ** Several functions have been removed from various sources:
2800 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
2801 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
2802 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
2803 pic16_assignRelocatableRegisters
2805 ** others have been introduced:
2806 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
2807 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
2809 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
2811 * support/scripts/inc2h.pl: changed definition of BIT_AT
2812 to emit 'sbit at' instead of 'bit at'. This was a request.
2814 PIC16 port related preliminary changes:
2815 * gen.c: prefixed function popRegFromString with
2816 pic16_ and all references to it corrected
2817 * pcode.c: all pic16_pc_* hardware registers prefixed
2818 with underscore (_),
2819 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
2820 * ralloc.c: newReg(): when register is REG_SFR then
2821 set address to rIdx,
2822 pic16_allocProcessorRegister(): marks register wasUsed=0
2823 pic16_writeUsedRegs(): added a call to assign processor
2824 registers via pic16_assignFixedRegisters
2826 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2828 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
2829 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
2830 variables in unused register banks. Also the SSEG is placed
2831 wherever there is enough space for it, and IDATA can be anywhere
2832 in internal RAM. For now compile using -Wl-Y[stack_size].
2833 The mem file is different for this option as well, since it
2834 makes no sense of talking about DSEG lenght.
2836 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
2838 * src/SDCClrange.c: fixed bug 869095 that caused segfault

3085 it breaks with bitfields, extern declarations, and gcse analysis.
3086 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
3087 could be assigned through a pointer, so don't complain.

3843 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
3844 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
3845 fetching of the pointer
3846 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
3847 copied from genNearPointerSet()
3848 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
3849 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
3850 If they pop r0/r1 they must be called in the opposite order than aopOp().
3851 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
3852 (resp. --stack-auto), prepared for --xstack

3863 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
3865 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3866 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
3867 type for bits was changed. It resulted in bit variables becoming
3868 global, which is not permitted in PIC 14 assembly output.
3870 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3872 * doc/sdccman.lyx: various additions and updates. Rearranged sections
3874 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3876 Z80 and MCS51 linkers complaint if a public symbol is defined

3885 A few small changes that speed up the peephole optimizer.
3889 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3891 Try to make the peephole optimizer smarter by maintaining
3892 an association between the assembly source code and the
3893 iCodes that originated them. Put this information to use
3894 with a new peephole rule condition "notVolatile" so that
3895 the rules can be aggressive yet still safe.
3900 * src/mcs51/peeph.def
3902 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3906 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
3907 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
3908 if the left or right operand symbols have the accuse flag set.
3910 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3912 Changed the type of the result of the ! (NOT) operator to char;
3913 previously it returned the same type as the source. This allows
3914 us to eliminate all the genFloatNot functions (all of its target
3915 implementations were very buggy) since !float can use the same
3918 * src/SDCCicode.c (ast2iCode): ! returns char

3920 * src/ds390/gen.c (genNot, genNotFloat),
3921 * src/z80/gen.c (genNot, genNotFloat),
3922 * src/pic/gen.c (genNot, genNotFloat),
3923 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
3925 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
3927 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3928 1. Interrupt would not compile properly. Ensure PCLATH register is saved
3929 during interrupts. Ensure WSAVE is located at a shared bank address.
3930 2. Fixed page selection in some places
3931 3. Fixed BTFSS/C to where necessary use registers directly and not simply
3932 the registers name strings.
3933 4. Fixed "signed / unsigned compare" compiler warnings.
3934 5. The PIC port manages its own allocation of the general purpose
3935 registers, but makes no attempt to reuse them. As a result when
3936 compiling it soon runs out of general purpose registers. Some
3937 additional code was added to the files pcode.c and device.c to walk
3938 through the function call tree and rename the registers so that they
3948 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
3949 genPlus() & genMinus() when the result is the same as left or right

3955 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3957 Made bitfield a distinct type from bit so that bitfields
3958 convert as per ANSI C and bits retain their traditional
3959 boolean style behaviour. Implemented bitfield support in
3967 * src/ds390/gen.c: bit v bitfield split
3968 * src/z80/gen.c: New support for bitfields
3969 * support/regression/tests/bitfields.c: reenabled z80,
3972 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3974 Rules 246.x, 247.x relate to bitfields, the others speed up
3975 access to xdata mapped I/O devices.
3977 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
3979 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3981 Cleaned up genPackBits and genUnpackBits and added two helper
3982 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
3983 for literal assignments in genPackBits (thanks to Frieder for
3989 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3991 Fixed bug #748310 (pointer to function type mishandled when the
3992 function name is omitted). Also fixed a SIGSEGV when a function
3993 attribute (reentrant, etc) is used on a non-function or on a
3994 function but misplaced before the parameter list.
3996 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
3998 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

4021 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4023 Made the constant following the "interrupt" keyword optional. If
4024 omitted, the function will not automatically be given an entry
4025 in the interrupt vector table (similar to #pragma NOIV, but
4026 less syntacticly kludgy). The interrupt number is also now
4027 range checked. Also fixed a bug in the high order bit example
4034 * support/Util/SDCCerr.c
4035 * support/Util/SDCCerr.h
4038 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

4041 * src/SDCCicode.c (operandOperation): rewritten some ops
4042 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
4043 * src/SDCCsymt.c (computeType): literals are handled the same way as any
4045 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
4046 be re-activated by defining REDUCE_LITERALS)
4047 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
4048 unsigned, but are signed by default
4049 * src/SDCCval.c (constVal): rearranged
4050 * src/SDCCval.c (valMod): preliminary fix
4051 * src/SDCCval.c (valCastLiteral): use TYPE_* types

4503 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
4504 the regression tests I'm not brave enough to enable 245.b, 245.c
4505 * doc/sdccman.lyx: added latex preamble for hyperref package.
4506 Using pdflatex this will give you a hyperlinked pdf file with
4507 bookmarks. (prepend '%' before /usepackage if this breaks something)

4545 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
4547 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
4548 it can be defined with CFLAGS when running configure
4549 * src/SDCCmain.c: fixed compiling + linking with object files
4551 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

4554 added --disable-pic16-port
4555 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
4556 * src/SDCCmain.c: linkOptions is changed to set *,
4557 added if/endif conditional macros to remove options help
4558 messages from optionsTable when a port is not configured, added
4559 support for the PIc16 port in the ports table, when executing
4560 the compiler with no port specified on command line, a default
4561 port is selected with the new macro DEFAULT_PORT which is
4562 defined in port.h, in setDefaultOptions() linkOptions is removed
4563 from initialization assignment, since now it is a set,
4564 parseCmdLine uses setParseWithComma for linkOptions, in
4565 linkEdit() linkOptions are accessed with new function indexSet()
4566 which returns the i'th item of a set variable. See SDCCset.c, in
4567 linkEdit() when calling buildCmdLine(), added linkOptions as
4568 last argument. Now users can pass arguments to gplink via the
4569 -Wl option, main() uses pic16glue() to glue up pic16 programs

4581 * src/pic16/glue.c: commented out some error producing lines
4582 * src/pic16/main.c: __config directives are commented out to stop
4583 gpasm complaining and test the linkage with gplink, _linkCmd and
4584 _asmCmd changed to be more gplink and gpasm friendly
4585 * src/pic16/peeph.def: peep rule 3 is commented out, since it
4586 produced an error when parsed, peep rule 12 is added to utilize
4587 movff, but it is commented out since the pCode does not support
4588 yet a command with 2 address arguments
4590 2003-05-18 <johan AT balder>
4592 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

4619 2003-05-11 Borut Razem <borut.razem AT siol.net>
4621 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
4622 the path of bin directory, so that PATH is the only env. variable, which has to be set
4623 in case of standard installation.
4624 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

5706 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
5707 not bytes. Function summary() which creates a memory usage summary
5708 file with extension .mem. Reports of overlaping stack and small stack
5709 size. If the space for the stack is less than 16 bytes aslink trows a
5712 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
5713 the 8051. Option 'y' for memory summary output file.
5715 Changes to sdcc (All the changes are marked with 'JCF'):
5717 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
5719 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
5720 overlaying area for it (uses RegBankUsed[4]).
5722 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
5723 bank zero as used by default. By default aslink locates the stack
5724 (equivalent to --stack-after-data). Pass option 'y' to aslink for
5725 the creation of the .mem file. Delegates the allocation of data area
5726 to aslink (it is not longer 0x30 by default). If --stack-loc passes
5727 the begining of the stack area to aslink.
5729 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
5730 glue() in SDCCglue.c creates an area for it.
5732 2002-09-03 Borut Razem <borut.razem AT siol.net>
5733 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
5734 sdcc/src/pic/glue.c:
5735 introduced atexit() handler for teporay files removal in case of
5736 errors, assertions, ...
5738 2002-08-29 Borut Razem <borut.razem AT siol.net>
5739 * sdcc/support/cpp2/auto-host_vc_in.h:
5740 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
5741 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
5742 Maybe there is a similar problem with BORLANDC? It should be checked!
5744 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
5745 corrected improper use of assert: the assignment to clr variable was done inside the assert.
5746 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
5747 was not executed, and the compiler (cl) launched a warning:
5748 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
5750 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
5751 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
5753 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
5754 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
5756 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5757 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
5758 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
5759 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5760 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
5761 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
5762 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
5763 - added Release configuration in VS projects
5764 - review of compiler an linker options
5765 - VC .exe files are generated in bin_vc directory, not to interfere
5766 with binaries generated from other projects (cygwin, mingw, bcc ...)
5768 * sdcc/src/yacc.dsp: added
5770 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
5771 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
5772 and insert the version number definitions from .version
5774 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
5776 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
5777 added - genarate auto-host.h using auto-host_vc_in.h as template
5780 removed from CVS, generated automatically
5782 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
5783 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
5785 2002-08-11 Borut Razem <borut.razem AT siol.net>
5786 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
5788 2002-08-10 Borut Razem <borut.razem AT siol.net>
5789 * src/SDCCmain.c (main):
5790 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
5791 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
5792 The consequence was that some temporary files were not removed.
5795 unification of code in functions tempfilename() and tempfile():
5796 function tempnam() is defined in Visual Studio 6.0 and .NET
5798 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
5800 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5801 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
5802 - removed compiler command line option /WX: Treats all warnings as errors
5803 - update a list of source files, included into the project
5805 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5806 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
5807 changed project type to Generic Project so that can be correcly converted to VS.NET project
5809 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
5811 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
5813 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
5815 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
5816 added return 0 statements after assert() to make compiler happy
5818 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
5819 added newline in the def file to keep MSC compiler satisfied
5821 * sdcc/src/z80/gen.c:
5822 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
5823 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
5824 - solved MSC error in function aopDump()
5826 * sdcc_vc.h: define PREFIX as "\\sdcc"
5828 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
5829 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

5877 Added -p option. Allows port dependent processor to be specified.
5880 Initialized the new field char *Processor field to NULL in all ports
5883 Compiler generated registers for interrupt context saving
5884 were not getting allocated.
5886 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
5889 Fixed left shift. Will promote the left side of a left shift
5890 if a) left shifting more than size of operand or b) when assigned
5891 to something size > size of left side
5893 2002-03-14 Scott Dattalo <scott AT dattalo.com>

6001 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
6003 * sdcc/src/SDCCloop.c:
6004 Previous fix was not good. basic blocks that have "break" or "return" are
6005 not really partof a loop , but live ranges used in these blocks should
6006 be live thru the entire loop, so set partOfLoop but don't add them to
6009 2002-02-21 <johan AT FRIJA>
6011 * src/SDCCcse.c: fixed bug #514308
6013 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

6017 statement inside a loop, it was not being considered part of the loop.
6019 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
6021 2002-02-10 Karl Bongers <karl AT turbobit.com>
