Sat Jun 13 11:33:55 1998 Alan Modra <alan@spri.levels.unisa.edu.au>
* i386-dis.c: Don't print opcode suffix when we can figure out the
size (and gas can!) by register operands, or from the default
size.
(putop): Handle 'A', 'B', 'L', 'P', 'Q', 'R' macros. Rename 'C'
macro to 'E'.
(dis386, dis386_twobyte, grps): Use new suffix macros.
(dis386): Correct imul Ib to imul sIb. Change jnl to jge to be
consistent. Add suffix for call, jmp, lcall, ljmp, iret. Reverse
order of cmps operands to agree with Intel docs. Correct operand
of aad and aam (Ib -> sIb). Change ud2b from 0fb8 to 0fb9 to
agree with Intel docs.
(print_insn_x86): Print orphan fwait before other prefixes.
Return correct byte count for orphan fwait with prefixes. Don't
print `bound' operands in reverse order.
(ckprefix): Stop accumulating prefixes if we get fwait.
(OP_DIR): Print `$' before Ap operands of ljmp, lcall.

macro to 'E'.
(dis386, dis386_twobyte, grps): Use new suffix macros.
(dis386): Correct imul Ib to imul sIb. Change jnl to jge to be

* i386-dis.c: Don't print opcode suffix when we can figure out the
size (and gas can!) by register operands, or from the default
size.
(putop): Handle 'A', 'B', 'L', 'P', 'Q', 'R' macros. Rename 'C'
macro to 'E'.
(dis386, dis386_twobyte, grps): Use new suffix macros.
(dis386): Correct imul Ib to imul sIb. Change jnl to jge to be
consistent. Add suffix for call, jmp, lcall, ljmp, iret. Reverse
order of cmps operands to agree with Intel docs. Correct operand
of aad and aam (Ib -> sIb). Change ud2b from 0fb8 to 0fb9 to
agree with Intel docs.
(print_insn_x86): Print orphan fwait before other prefixes.
Return correct byte count for orphan fwait with prefixes. Don't
print `bound' operands in reverse order.
(ckprefix): Stop accumulating prefixes if we get fwait.
(OP_DIR): Print `$' before Ap operands of ljmp, lcall.

* i386-dis.c: Don't print opcode suffix when we can figure out the
size (and gas can!) by register operands, or from the default
size.
(putop): Handle 'A', 'B', 'L', 'P', 'Q', 'R' macros. Rename 'C'
macro to 'E'.
(dis386, dis386_twobyte, grps): Use new suffix macros.
(dis386): Correct imul Ib to imul sIb. Change jnl to jge to be
consistent. Add suffix for call, jmp, lcall, ljmp, iret. Reverse
order of cmps operands to agree with Intel docs. Correct operand
of aad and aam (Ib -> sIb). Change ud2b from 0fb8 to 0fb9 to
agree with Intel docs.
(print_insn_x86): Print orphan fwait before other prefixes.
Return correct byte count for orphan fwait with prefixes. Don't
print `bound' operands in reverse order.
(ckprefix): Stop accumulating prefixes if we get fwait.
(OP_DIR): Print `$' before Ap operands of ljmp, lcall.

* i386-dis.c: Don't print opcode suffix when we can figure out the
size (and gas can!) by register operands, or from the default
size.
(putop): Handle 'A', 'B', 'L', 'P', 'Q', 'R' macros. Rename 'C'
macro to 'E'.
(dis386, dis386_twobyte, grps): Use new suffix macros.
(dis386): Correct imul Ib to imul sIb. Change jnl to jge to be
consistent. Add suffix for call, jmp, lcall, ljmp, iret. Reverse
order of cmps operands to agree with Intel docs. Correct operand
of aad and aam (Ib -> sIb). Change ud2b from 0fb8 to 0fb9 to
agree with Intel docs.
(print_insn_x86): Print orphan fwait before other prefixes.
Return correct byte count for orphan fwait with prefixes. Don't
print `bound' operands in reverse order.
(ckprefix): Stop accumulating prefixes if we get fwait.
(OP_DIR): Print `$' before Ap operands of ljmp, lcall.
