[fw/sdcc] / ChangeLog

2002-08-29  Borut Razem <borut.razem@siol.net>
        * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
        corrected improper use of assert: the assignment to clr variable was done inside the assert.
        In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
        was not executed, and the compiler (cl) launched a warning:
        ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized

2002-08-28  Bernhard Held <bernhard@bernhardheld.de>
        * src/SDCCglue.c (printIvalArray): iterative calculation of array length

2002-08-28  Jesus Calvino-Fraga and Borut Razem <borut.razem@siol.net>
        * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects

        * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
          sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
          sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
          sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
          sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
          sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
          sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
        - added Release configuration in VS projects
        - review of compiler an linker options
        - VC .exe files are generated in bin_vc directory, not to interfere
          with binaries generated from other projects (cygwin, mingw, bcc ...)

        * sdcc/src/yacc.dsp: added

        * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
        added - genarate sdcc_vc.h using sdcc_vc_in.h as template
        and insert the version number definitions from .version 

        * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp

        * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
        added - genarate auto-host.h using auto-host_vc_in.h as template

        * sdcc/sdcc_vc.h,
        removed from CVS, generated automatically

2002-08-25  Bernhard Held <bernhard@bernhardheld.de>
        * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)

2002-08-11  Borut Razem <borut.razem@siol.net>
        * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)

2002-08-10  Borut Razem <borut.razem@siol.net>
        * src/SDCCmain.c (main):
        file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
        platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
        The consequence was that some temporary files were not removed.

        * src/SDCCglue.c:
        unification of code in functions tempfilename() and tempfile():
        function tempnam() is defined in Visual Studio 6.0 and .NET

        * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a

        * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
          sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
        - removed compiler command line option /WX: Treats all warnings as errors
        - update a list of source files, included into the project

        * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
          sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
        changed project type to Generic Project so that can be correcly converted to VS.NET project

        * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC

        * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

        * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings

        * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
        added return 0 statements after assert() to make compiler happy

        * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
        added newline in the def file to keep MSC compiler satisfied

        * sdcc/src/z80/gen.c:
        - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
          so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
        - solved MSC error in function aopDump()

        * sdcc_vc.h: define PREFIX as "\\sdcc"

2002-07-18  Bernhard Held <bernhard@bernhardheld.de>
        * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

2002-06-22  Scott Dattalo <scott@dattalo.com>
        * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced. 
        - Rewrote the register banking algorithm. 
        - Added pCode live-range analysis to registers (for now, only non-used and 
        singly-used registers optimized away)

        * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis

        * support/scripts/inc2h.pl Kevin L. Pauba <klpauba@cox.net> submitted this perl script for converting MicroChip include files into SDCC Pic include files.
        
2002-05-10  Scott Dattalo <scott@dattalo.com>

        * src/z80/ralloc.c (packRegisters): Disabled pack HL use for GB as it's broken.

        * src/z80/peeph.def: Added transpose redundent load rule.

        * src/z80/main.c: Added force callee saves for jaune.

        * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.

        * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.

2002-03-28  Johan Knol  <johan@balder>

        * src/SDCCval.c: fixed bug #532436

2002-03-14  Scott Dattalo <scott@dattalo.com>
        * /src/port.h:
        Added "char *Processor" field to the port structure.

        * /src/SDCCmain.c:
        Added -p option. Allows port dependent processor to be specified.

        * all ports:
        Initialized the new field char *Processor field to NULL in all ports

        * /src/pic/*:
        Compiler generated registers for interrupt context saving
        were not getting allocated.
                
2002-03-16  Sandeep Dutta  <sandeep@ddi.com>

        * /src/SDCCast.c:
        Fixed left shift. Will promote the left side of a left shift
        if a) left shifting more than size of operand or b) when assigned
        to something size > size of left side

2002-03-14  Scott Dattalo <scott@dattalo.com>
        * src/pic/*
        tons of changes. Register allocation has been 
        rewritten. Added customization for the various PICs. Flow
        analysis is restructured. ...

        * src/pic/device.h:
        Added

        * src/pic/device.c:
        Added. device.c is a PIC port hack to accomodate variations
        in PIC devices.

2002-03-13  Michael Hope  <michaelh@vroom>

        * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled.  Yeah.

2002-03-04  johanknol  <johanknol@manik>

        * /src/SDCCval.c: fixed

2002-02-21  Sandeep Dutta  <sandeep@ddi.com>

        * sdcc/src/SDCCloop.c:
        Previous fix was not good. basic blocks that have "break" or "return" are
        not really partof a loop , but live ranges used in these blocks should
        be live thru the entire loop, so set partOfLoop but don't add them to
        loop region

        * src/SDCCcse.c: fixed bug #514308

2002-02-20  Sandeep Dutta  <sandeep@ddi.com>

        statement inside a loop, it was not being considered part of the loop.

        * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)

2002-02-10  Karl Bongers <karl@turbobit.com>

        Fix bug, "red" variable not being initialized(compiler complained).

        * device/examples/Makefile, examples/test3.c:
        Add Makefile in device/examples folder, compiles test3.c
        for use as a multiple module SDCDB test case.

        * sim/ucsim/cmd.src/cmdset.cc:
        Took out debug printfs in ucsim "next" command.

        * sim/ucsim/xa.src:
        Karl and Johan start ucsim XA support.  Most dissassembly working,
        about 75% emulation done(plenty of work remaining).

        * sim/ucsim/z80.src:
        Add Z80 support to ucsim, add test-ucz80 regression test,
        notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
        Notice z80 compiler fails on examples/test3.c/crc code.
