* R600/SI: Custom lower SI_IF and SI_ELSE to avoid machine verifier errorsTom Stellard2014-04-29
| | | | | | | | | | | | | | | | SI_IF and SI_ELSE are terminators which also produce a value. For these instructions ISel always inserts a COPY to move their value to another basic block. This COPY ends up between SI_(IF|ELSE) and the S_BRANCH* instruction at the end of the block. This breaks MachineBasicBlock::getFirstTerminator() and also the machine verifier which assumes that terminators are grouped together at the end of blocks. To solve this we coalesce the copy away right after ISel to make sure there are no instructions in between terminators at the end of blocks. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@207591 91177308-0d34-0410-b5e6-96231b3b80d8
* R600/SI: Only select SALU instructions in the entry or exit blockTom Stellard2014-04-29
| | | | | | | | SALU instructions ignore control flow, so it is not always safe to use them within branches. This is a partial solution to this problem until we can come up with something better. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@207590 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | When legalizing ops, with UDIV/UREM set to expand, they automatically expand to UDIVREM (if legal or custom). We need to do this manually for legalize types. v2: SI should be set to Expand because the type is legal, and it is automatically lowered to UDIVREM if UDIVREM is Legal/Custom R600 should set to UDIV/UREM to Custom because it needs to lower them during type legalization Patch by: Jan Vesely Signed-off-by: Jan Vesely <jan.vesely@rutgers.edu> Reviewed-by: Tom Stellard <thomas.stellard@amd.com> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@207587 91177308-0d34-0410-b5e6-96231b3b80d8

* PR19553: Memory leak in RuntimeDyldELF::createObjectImageFromFileDavid Blaikie2014-04-29
| | | | | | | | | | | | | | | | This starts in MCJIT::getSymbolAddress where the unique_ptr<object::Binary> is release()d and (after a cast) passed to a single caller, MCJIT::addObjectFile. addObjectFile calls RuntimeDyld::loadObject. RuntimeDld::loadObject calls RuntimeDyldELF::createObjectFromFile And the pointer is never owned at this point. I say this point, because the alternative codepath, RuntimeDyldMachO::createObjectFile certainly does take ownership, so this seemed like a good hint that this was a/the right place to take ownership. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@207580 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | Change `BlockFrequency` to defer to `BranchProbability::scale()` and `BranchProbability::scaleByInverse()`. This removes `BlockFrequency::scale()` from its API (and drops the ability to see the remainder), but the only user was the unit tests. If some code in the future needs an API that exposes the remainder, we can add something to `BranchProbability`, but I find that unlikely. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@207550 91177308-0d34-0410-b5e6-96231b3b80d8

* Centralize the handling of the thumb bit.Rafael Espindola2014-04-29
| | | | | | | | | | | | | This patch centralizes the handling of the thumb bit around MCStreamer::isThumbFunc and makes isThumbFunc handle aliases. This fixes a corner case, but the main advantage is having just one way to check if a MCSymbol is thumb or not. This should still be refactored to be ARM only, but at least now it is just one predicate that has to be refactored instead of 3 (isThumbFunc, ELF_Other_ThumbFunc, and SF_ThumbFunc). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@207522 91177308-0d34-0410-b5e6-96231b3b80d8
