* llvm-cov: Expect a source file as a positional parameterJustin Bogner2014-01-29
| | | | | | | | | | | Currently, llvm-cov isn't command-line compatible with gcov, which accepts a source file name as its first parameter and infers the gcno and gcda file names from that. This change keeps our -gcda and -gcno options available for convenience in overriding this behaviour, but adds the required parameter and inference behaviour as a compatible default. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200417 91177308-0d34-0410-b5e6-96231b3b80d8

* MC: Better management of macro argumentsDavid Majnemer2014-01-29
| | | | | | | | | | | | | The linux kernel makes uses of a GAS `feature' which substitutes nothing for macro arguments which aren't specified. Proper support for these kind of macro arguments necessitated a cleanup of differences between `GAS' and `Darwin' dialect macro processing.

* [LPM] Fix PR18643, another scary place where loop transforms failed toChandler Carruth2014-01-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | preserve loop simplify of enclosing loops. The problem here starts with LoopRotation which ends up cloning code out of the latch into the new preheader it is buidling. This can create a new edge from the preheader into the exit block of the loop which breaks LoopSimplify form. The code tries to fix this by splitting the critical edge between the latch and the exit block to get a new exit block that only the latch dominates. This sadly isn't sufficient. The exit block may be an exit block for multiple nested loops. When we clone an edge from the latch of the inner loop to the new preheader being built in the outer loop, we create an exiting edge from the outer loop to this exit block. Despite breaking the LoopSimplify form for the inner loop, this is fine for the outer loop. However, when we split the edge from the inner loop to the exit block, we create a new block which is in neither the inner nor outer loop as the new exit block. This is a predecessor to the old exit block, and so the split itself takes the outer loop out of LoopSimplify form. We need to split every edge entering the exit block from inside a loop nested more deeply than the exit block in order to preserve all of the loop simplify constraints. Once we try to do that, a problem with splitting critical edges surfaces. Previously, we tried a very brute force to update LoopSimplify form by re-computing it for all exit blocks. We don't need to do this, and doing this much will sometimes but not always overlap with the LoopRotate bug fix. Instead, the code needs to specifically handle the cases which can start to violate LoopSimplify -- they aren't that common. We need to see if the destination of the split edge was a loop exit block in simplified form for the loop of the source of the edge. For this to be true, all the predecessors need to be in the exact same loop as the source of the edge being split. If the dest block was originally in this form, we have to split all of the deges back into this loop to recover it. The old mechanism of doing this was conservatively correct because at least *one* of the exiting blocks it rewrote was the DestBB and so the DestBB's predecessors were fixed. But this is a much more targeted way of doing it. Making it targeted is important, because ballooning the set of edges touched prevents LoopRotate from being able to split edges *it* needs to split to preserve loop simplify in a coherent way -- the critical edge splitting would sometimes find the other edges in need of splitting but not others. Many, *many* thanks for help from Nick reducing these test cases mightily. And helping lots with the analysis here as this one was quite tricky to track down. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200393 91177308-0d34-0410-b5e6-96231b3b80d8

* Enable EHABI by defaultRenato Golin2014-01-29
| | | | | | | | | | | | | | | | | | | | | | After all hard work to implement the EHABI and with the test-suite passing, it's time to turn it on by default and allow users to disable it as a work-around while we fix the eventual bugs that show up. This commit also remove the -arm-enable-ehabi-descriptors, since we want the tables to be printed every time the EHABI is turned on for non-Darwin ARM targets. Although MCJIT EHABI is not working yet (needs linking with the right libraries), this commit also fixes some relocations on MCJIT regarding the EH tables/lib calls, and update some tests to avoid using EH tables when none are needed. The EH tests in the test-suite that were previously disabled on ARM now pass with these changes, so a follow-up commit on the test-suite will re-enable them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200388 91177308-0d34-0410-b5e6-96231b3b80d8
* MC: Reorganize macro MC test along dialect linesDavid Majnemer2014-01-29
| | | | | | | | | | | | This commit seeks to do two things: - Run the surfeit of tests under the Darwin dialect. This ends up affecting tests which assumed that spaces could deliminate arguments. - The GAS dialect tests should limit their surface area to things that could plausibly work under GAS. For example, Darwin style arguments have no business being in such a test. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200383 91177308-0d34-0410-b5e6-96231b3b80d8

* [LPM] Fix PR18642, a pretty nasty bug in IndVars that "never mattered"Chandler Carruth2014-01-29
| | | | | | | | | | | | | | | | | | | | | | | because of the inside-out run of LoopSimplify in the LoopPassManager and the fact that LoopSimplify couldn't be "preserved" across two independent LoopPassManagers. Anyways, in that case, IndVars wasn't correctly preserving an LCSSA PHI node because it thought it was rewriting (via SCEV) the incoming value to a loop invariant value. While it may well be invariant for the current loop, it may be rewritten in terms of an enclosing loop's values. This in and of itself is fine, as the LCSSA PHI node in the enclosing loop for the inner loop value we're rewriting will have its own LCSSA PHI node if used outside of the enclosing loop. With me so far? Well, the current loop and the enclosing loop may share an exiting block and exit block, and when they do they also share LCSSA PHI nodes. In this case, its not valid to RAUW through the LCSSA PHI node. Expected crazy test included. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200372 91177308-0d34-0410-b5e6-96231b3b80d8

* Remove unnecessary call to pthread_mutexattr_setpshared()Mark Seaborn2014-01-29
| | | | | | | | | | | | | | | | | | | The default value of this attribute is PTHREAD_PROCESS_PRIVATE, so there's no point in calling pthread_mutexattr_setpshared() to set that. See: http://pubs.opengroup.org/onlinepubs/9699919799/functions/pthread_mutexattr_getpshared.html This removes some ifdefs that tend to need to be extended for other platforms (e.g. for NaCl). Note that this call was in the first implementation of Mutex, added in r22403, so it doesn't appear to have been added in response to a performance problem.
