Convert the uses of '\|&' to use '2>&1 \|' instead, which works on old versions of Bash. In addition, I can back out the change to the lit built-in shell test runner to support this. This should fix the majority of fallout on Darwin, but I suspect there will be a few straggling issues. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159544 91177308-0d34-0410-b5e6-96231b3b80d8 2012-07-02 18:37:59 +00:00			`; RUN: opt < %s -basicaa -aa-eval -disable-output 2>&1 \| FileCheck %s`
Extend the 'noalias' attribute to function return values. This is intended to indicate functions that allocate, such as operator new, or list::insert. The actual definition is slightly less strict (for now). No changes to the bitcode reader/writer, asm printer or verifier were needed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59934 91177308-0d34-0410-b5e6-96231b3b80d8 2008-11-24 03:41:24 +00:00

[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			`%C = load i32, i32* %A`
