Subject: [Xen-devel] [PATCH v10 10/13] x86emul: restore ordering within main switch statement
Date: Wed, 17 Jul 2019 06:36:57 +0000 [thread overview]
Message-ID: <be1f05ff-6159-7fca-4316-daa55f840a78@suse.com> (raw)
In-Reply-To: <0ccca19e-7bbb-ab1e-c0bb-a568b02874e0@suse.com>
Incremental additions and/or mistakes have lead to some code blocks
sitting in "unexpected" places. Re-sort the case blocks (opcode space;
major opcode; 66/F3/F2 prefix; legacy/VEX/EVEX encoding).
As an exception the opcode space 0x0f EVEX-encoded VPEXTRW is left at
its current place, to keep it close to the "pextr" label.
Pure code movement.
