| |
Hello.
OK, let me resend everything. This is what I am going to add to my tree and ask Ingo to pull. I am still testing this all, seems to work so far.
Changes:
01-09: No changes, added the acks from Masami.
09-15: Updated the changelogs, the comments in 13/15, plus the following renames:
- s/ttt/branch/
- s/disp/offs/
- s/_clear_displacement/_clear_offset/
No changes in compiled code, I preserved the acks from Jim.
From 13/15:
Note: as Denys Vlasenko pointed out, amd and intel treat "callw" (0x66 0xe8) differently. This patch relies on lib/insn.c and thus implements the intel's behaviour: 0x66 is simply ignored. Fortunately nothing sane should ever use this insn, so we postpone the fix until we decide what should we do; emulate or not, support or not, etc.
Yes. Lets discuss (and fix?) this separately, I'll write another email.
Any objections?
Oleg.
