Add a AVX version of a simple i64 -> f64 bitcast. This could be triggered using llc with -O0, which wouldn't let it be folded and expose the lack of this pattern. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139320 91177308-0d34-0410-b5e6-96231b3b80d8 2011-09-08 21:52:33 +00:00			`; RUN: llc < %s -O0 -mtriple=x86_64-apple-darwin -mcpu=corei7-avx -mattr=+avx \| FileCheck %s`

Remove some instructions that existed to provide aliases to the assembler. Can be done with InstAlias instead. Unfortunately, this was causing printer to use 'vmovq' or 'vmovd' based on what was parsed. To cleanup the inconsistencies convert all 'vmovd' with 64-bit registers to 'vmovq', but provide an alias so that 'vmovd' will still parse. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@192171 91177308-0d34-0410-b5e6-96231b3b80d8 2013-10-08 05:53:50 +00:00			`; CHECK-NEXT: vmovq %xmm`

[opaque pointer type] Add textual IR support for explicit type parameter to load instruction Essentially the same as the GEP change in r230786. A similar migration script can be used to update test cases, though a few more test case improvements/changes were required this time around: (r229269-r229278) import fileinput import sys import re pat = re.compile(r"((?:=\|:\|^)\sload (?:atomic )?(?:volatile )?(.?))(\| addrspace\(\d+\) )\($\| (?:%\|@\|null\|undef\|blockaddress\|getelementptr\|addrspacecast\|bitcast\|inttoptr\|\[\[[a-zA-Z]\|\{\{).$)") for line in sys.stdin: sys.stdout.write(re.sub(pat, r"\1, \2\3*\4", line)) Reviewers: rafael, dexonsmith, grosser Differential Revision: http://reviews.llvm.org/D7649 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@230794 91177308-0d34-0410-b5e6-96231b3b80d8 2015-02-27 21:17:42 +00:00			`%a = load double, double* undef`
