2013-04-18[objc-arc] Do not mismatch up retains inside a for loop with releases ↵Michael Gottesman
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

2013-04-17Two small cleanups for ELF's templates.Rafael Espindola
* We only ever specialize these templates with an instantiation of ELFType, so we don't need a template template. * Replace LLVM_ELF_COMMA with just passing the individual parameters to the macro. This requires a second macro for when we only have ELFT, but that is still a small win. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179726 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-17A limit of 500 was still a bit too high for some tests.Bill Wendling
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.

2013-04-17Fix treatment of ARM unallocated hint instructions.Quentin Colombet
