* Allow misaligned stores in x86 fast-isel.Derek Schuff2013-04-182-5/+18
| | | | | | | | | | | | In X86FastISel::X86SelectStore(), improperly aligned stores are rejected and handled by the DAG-based ISel. However, X86FastISel::X86SelectLoad() makes no such requirement. There doesn't appear to be an x86 architectural correctness issue with allowing potentially unaligned store instructions. This patch removes this restriction. Patch by Jim Stichnot. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179774 91177308-0d34-0410-b5e6-96231b3b80d8
* LoopVectorizer: Recognize min/max reductionsArnold Schwaighofer2013-04-182-34/+608
| | | | | | | | | | | | A min/max operation is represented by a select(cmp(lt/le/gt/ge, X, Y), X, Y) sequence in LLVM. If we see such a sequence we can treat it just as any other commutative binary instruction and reduce it. This appears to help bzip2 by about 1.5% on an imac12,2. radar://12960601 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179773 91177308-0d34-0410-b5e6-96231b3b80d8

* [objc-arc] Do not mismatch up retains inside a for loop with releases ↵Michael Gottesman2013-04-182-96/+167
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | outside said for loop in the presense of differing provenance caused by escaping blocks. This occurs due to an alloca representing a separate ownership from the original pointer. Thus consider the following pseudo-IR: objc_retain(%a) for (...) { objc_retain(%a) %block <- %a F(%block) objc_release(%block) } objc_release(%a) From the perspective of the optimizer, the %block is a separate provenance from the original %a. Thus the optimizer pairs up the inner retain for %a and the outer release from %a, resulting in segfaults. This is fixed by noting that the signature of a mismatch of retain/releases inside the for loop is a Use/CanRelease top down with an None bottom up (since bottom up the Retain-CanRelease-Use-Release sequence is completed by the inner objc_retain, but top down due to the differing provenance from the objc_release said sequence is not completed). In said case in CheckForCFGHazards, we now clear the state of %a implying that no pairing will occur. Additionally a test case is included. rdar://12969722 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179747 91177308-0d34-0410-b5e6-96231b3b80d8

* A limit of 500 was still a bit too high for some tests.Bill Wendling2013-04-171-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PR15000 has a testcase where the time to compile was bordering on 30s. When I dropped the limit value to 100, it became a much more managable 6s. The compile time seems to increase in a roughly linear fashion based on increasing the limit value. (See the runtimes below.) So, let's lower the limit to 100 so that they can get a more reasonable compile time.
