=================== BUG #5217: FULL BUG SNAPSHOT ===================
http://savannah.nongnu.org/bugs/?func=detailbug&bug_id=5217&group_id=1953
Submitted by: jrydberg Project: GUSS
Submitted on: Thu 09/11/2003 at 19:27
Category: i386-target Severity: 3
Bug Group: feature request Resolution: None
Assigned to: jrydberg Status: Open
Summary: addsi_a0_seg_base is too slow
Original Submission: The current implementation of addsi_a0_seg_base results
in the following code:
mov $0x0,%eax
R_386_32 __op_param1
lea 0x0(,%eax,4),%eax
R_386_32 __op_param1
add 0x58(%ebp,%eax,4),%edi
Which is _too_ much. This could probably be replaced with
just one insn (the add) if you give the address to the
base directly as a parameter to the micro-op.
