[llvm] Remove redundant --check-prefix=CHECK from tests Reviewers: MatzeB, mcrosier, rengolin Differential Revision: https://reviews.llvm.org/D25894 llvm-svn: 285003 2016-10-25 02:57:55 +08:00			`; RUN: llc -mtriple=x86_64-unknown-unknown -mcpu=core-avx-i < %s \| FileCheck %s`
Enhance type legalization on bitcast from vector to integer - Find a legal vector type before casting and extracting element from it. - As the new vector type may have more than 2 elements, build the final hi/lo pair by BFS pairing them from bottom to top. llvm-svn: 163830 2012-09-14 03:58:21 +08:00
