9 years ago[X86] Removed (unused) FSRL x86 operation
Simon Pilgrim [Wed, 3 Jun 2015 08:32:36 +0000 (08:32 +0000)]
[X86] Removed (unused) FSRL x86 operation

This patch removes the old X86ISD::FSRL op - which allowed float vectors to use the byte right shift operations (causing a domain switch....).

Since the refactoring of the shuffle lowering code this no longer has any use.
