[fw/sdcc] / ChangeLog

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/pic/*: Added support for multiplication. Fixed many,many bugs.

        * 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/pic/*
        tons of changes. Register allocation has been

        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

        Took out debug printfs in ucsim "next" command.

        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.

        * src/z80/gen.c (fetchLitPair): Changed so that it properly caches direct space references.

        * support/regression/tests/addsub.c: Added cases to cover all the +, - combinations.

        * support/regression/tests/uminus.c: Added a test for the unary minus operator.

        * src/z80/gen.c (genUminus): Fixed add, sub, and uminus on the gbz80 port for longs.  Had to shift some functions about to do it.

2001-09-01  Michael Hope  <michaelh@juju.net.nz>

        * src/z80/gen.c: Fixed up generator to pass the regresion tests, specifically fixing loads for longs, genCmp, and turned on the map file.
        (genCmp): Fixed up genCmp for the GB with longs.

        * device/lib/gbz80/Makefile: Fixed up all the libraries to pass the regression tests.

        * support/regression/ports/host/spec.mk: Updated to compile with the new type specifiers.

        * device/lib/Makefile.in (Z80SOURCES): Removed old _mululong, _mulslong, and unneeded _mulint.

        * device/lib/_mullong.c (_mulslong): Changed to actually return a value :)

        * added peepholes 223 to 231 to mcs51 port.  These improve code when using large model.

        * device/lib/gbz80/crt0.s (init): Fixed up support for the gbz80 such that it will at least run (and fail badly) the regression tests.

        * src/z80/gen.c (genPlus): Changed bad long add for gb to a fall through.

2001-08-29  Michael Hope  <michaelh@juju.net.nz>

        * link/z80/aslink.h: Fixed long file name support.  Is now based off PATH_MAX instead of a constant.

        * src/z80/gen.c: Fixed add and sub for the case where left or right are in static space.
