555 2001-09-04 Paul Stoffregen <paul@pjrc.com>
557 * pragma noinduction broke memcpy on mcs51 large model. Moved it inside z80 optimization
559 2001-09-03 Michael Hope <michaelh@juju.net.nz>
561 * link/z80/aslink.h: Fixed path for PATH_MAX
563 2001-09-02 Michael Hope <michaelh@juju.net.nz>
565 * src/z80/gen.c (fetchLitPair): Changed so that it properly caches direct space references.
567 * support/regression/tests/addsub.c: Added cases to cover all the +, - combinations.
569 * support/regression/tests/uminus.c: Added a test for the unary minus operator.
571 * 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.
573 2001-09-01 Michael Hope <michaelh@juju.net.nz>
575 * src/z80/gen.c: Fixed up generator to pass the regresion tests, specifically fixing loads for longs, genCmp, and turned on the map file.
576 (genCmp): Fixed up genCmp for the GB with longs.
578 * device/lib/gbz80/Makefile: Fixed up all the libraries to pass the regression tests.
580 * support/regression/ports/host/spec.mk: Updated to compile with the new type specifiers.
582 * device/lib/Makefile.in (Z80SOURCES): Removed old _mululong, _mulslong, and unneeded _mulint.
584 * device/lib/_mullong.c (_mulslong): Changed to actually return a value :)
586 2001-08-30 Paul Stoffregen <paul@pjrc.com>
588 * added peepholes 223 to 231 to mcs51 port. These improve code when using large model.
590 2001-08-30 Michael Hope <michaelh@juju.net.nz>
592 * 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.
594 * src/z80/gen.c (genPlus): Changed bad long add for gb to a fall through.
596 2001-08-29 Michael Hope <michaelh@juju.net.nz>
598 * link/z80/aslink.h: Fixed long file name support. Is now based off PATH_MAX instead of a constant.
600 * src/z80/gen.c: Fixed add and sub for the case where left or right are in static space.
