ceriel 876026bedf Some improvements 1987-09-29 09:03:49 +00:00
ceriel ae3c81e0a6 Made floating point stuff depend on a #define: FPPSIM 1987-02-02 09:59:02 +00:00
ceriel b6dde9472f Bug fix: The "cmp.l" instruction was sometimes used in an illegal way. 1986-09-10 16:03:11 +00:00
ceriel 023073b422 Bug fix: the BLS instruction did'nt work with block moves of one word. 1986-07-25 15:57:03 +00:00
bal c9c168d853 Several optimization patterns for DAS (Delftse Ada Subset) frontend added. 1985-10-14 09:27:24 +00:00
bal 7b4b53af21 bugs for ngf 8 and fif 4 fixed (asp 16 --> asp 8). 1985-07-19 18:02:25 +00:00
bal 2e5bf801a0 patterns for "loc loc cii/cui/ciu/cuu $1==$2" added. 1985-07-19 17:58:34 +00:00
bal 0db1db10b8 Bug fixed: cg generated instructions like "and.l #2,a4", which are
not allowed on the 68000.
The condition "inreg($...) < 2" is added to every EM-pattern that
accesses local non-register variables. So the ordering of the
patterns for regvar/non-regvar is no longer important.

bal 7b745d6fb2 Bug fixed for pattern 'sti $1 > 4' (ADDREG -> ADDSCR)
Bug was present since version 1.1

bal ca9a6feeb0 floating point stuff added 1985-04-12 15:47:30 +00:00
bal d1c0d1db13 Bugs fixed for the following patterns:
lol loc 255 and 2  (byte order was wrong)
loc x beq , 0 < x < 128  (was 0 < x < 256)
loc x bne (idem).
These bugs were introduced in version 2.2.

bal 46dc90f366 bug fixed: generate "add.l #65536,a1" rather than "lea 65536(a1),a1".
The latter form is only generated for constants that fit in a word.
1984-10-08 12:45:38 +00:00
bal f2e52892ac bugs fixed (syntax errors, patterns moved to front,
"ldl ldl adp sdl sti" requires DATAREG instead of ANY1 on
fakestack)
1984-07-30 11:16:41 +00:00
bal 233b4aeee4 patterns added to generate autoincrement and to generate
a "move X,d0" instead of a "move X,-(sp)" before storing into X

bal da4092cbdf New implementation of GTO (without register save masks)
several optimizations added
