25b344a4a2 No longer need to sanitize away h8s stuff. 1996-07-05 18:59:31 +00:00
Jeff Law
7647e0dd79 * run.c (main): Don't "load" sections which don't have 
SEC_LOAD set.
        * compile.c (sim_resume, case "O_NOT"): Use ONOT instead
        of OSHIFTS.
        (ONOT): Define.
        (sim_resume, shift/rotate cases): Add support for shift/rotate
        by two bits.
        (OSHIFTS): Corresponding changes.
Handling more H8/S ops.

171f4664be * compile.c (sim_resume): Handle "ldm.l" and "stm.l". 
HMSE H8/S.

7e1e013fd9 * compile.c (sim_resume): Correctly handle divu. 
More bugfixing.  HMSE

132fdcb974 * compile.c (sim_load): Re-allocate memory for the simulator 
here.
HMSE.

9b1271617b * compile.c (sim_resume): Fix and simplify overflow and carry 
handling for 32bit ALU insns.

50d45d1b2f * compile.c (sim_resume): Fix overflow checks for ALU insns. 
So that int-compare.c passes.

e24146ec95 * compile.c (decode): Use "bit" to hold L_3 immediates instead 
of holding them in "abs".  Handle ABS8MEM memory references aka
        8-bit area.  Replace ABSMOV references with ABS8MEM.
So we've got a chance of simulating something like btst #0,@40:8 correctly.
hmse.
