* Optimize comparison against 0 in conditional instructions.Wesley Peck2011-11-271-2/+156
| | | | | | Fix a couple of 80-column violations. llvm-svn: 145159
* Introduce a loop block rotation optimization to the new block placementChandler Carruth2011-11-272-3/+122
| | | | | | | | | | | | | | | pass. This is designed to achieve one of the important optimizations that the old code placement pass did, but more simply. This is a somewhat rough and *very* conservative version of the transform. We could get a lot fancier here if there are profitable cases to do so. In particular, this only looks for a single pattern, it insists that the loop backedge being rotated away is the last backedge in the chain, and it doesn't provide any means of doing better in-loop placement due to the rotation. However, it appears that it will handle the important loops I am finding in the LLVM test suite. llvm-svn: 145158

| | | | | | Simplify some shuffle lowering code since V1 can never be UNDEF due to canonalizing that occurs when shuffle nodes are created. llvm-svn: 145153

* Fix APFloat::convert so that it handles narrowing conversions correctly; itEli Friedman2011-11-263-50/+61
| | | | | | | | was returning incorrect values in rare cases, and incorrectly marking exact conversions as inexact in some more common cases. Fixes PR11406, and a missed optimization in test/CodeGen/X86/fp-stack-O0.ll. llvm-svn: 145141

* In Microsoft mode, make "Unqualified lookup into dependent bases of class ↵Francois Pichet2011-11-253-4/+40

That's because calling GetParent() return the namespace or file DeclContext. This fixes all remaining cases of "Unqualified lookup into dependent bases of class templates" when parsing MFC code with clang. llvm-svn: 145127

* Fix a silly use-after-free issue. A much earlier version of this codeChandler Carruth2011-11-242-2/+213
| | | | | | | | | | | | need lots of fanciness around retaining a reference to a Chain's slot in the BlockToChain map, but that's all gone now. We can just go directly to allocating the new chain (which will update the mapping for us) and using it. Somewhat gross mechanically generated test case replicates the issue Duncan spotted when actually testing this out. llvm-svn: 145120
* When adding blocks to the list of those which no longer have any CFGChandler Carruth2011-11-242-3/+59
| | | | | | | | | | | | | | conflicts, we should only be adding the first block of the chain to the list, lest we try to merge into the middle of that chain. Most of the places we were doing this we already happened to be looking at the first block, but there is no reason to assume that, and in some cases it was clearly wrong. I've added a couple of tests here. One already worked, but I like having an explicit test for it. The other is reduced from a test case Duncan reduced for me and used to crash. Now it is handled correctly. llvm-svn: 145119

Additional text will give the extra information about the nature of the mismatch: different classes for member functions, wrong number of parameters, different parameter type, different return type, and function qualifier mismatch. llvm-svn: 145114
* This patch makes the following changes necessary for MIPS' direct code emission.Akira Hatanaka2011-11-236-55/+236

| | | | | | | | | | | | | | | file region inside an objc container that "contains" other file-level declarations. When getting the array of file-level declarations that overlap with a file region, we failed to report that the region overlaps with an objc container, if the container had other file-level declarations declared lexically inside it. Fix this by marking such declarations as "isTopLevelDeclInObjCContainer" in the AST and handling them appropriately. llvm-svn: 145109

* Fix a crash in which a multiplication was being reported as being both negativeDuncan Sands2011-11-232-2/+24
| | | | | | | | and positive: positive, because it could be directly computed to be positive; negative, because the nsw flags means it is either negative or undefined (the multiplication always overflowed). llvm-svn: 145104
* X86: Use btq for bit tests if the immediate can't be encoded in 32 bits.Benjamin Kramer2011-11-232-1/+44
| | | | | | | | | | | | | | | | Before: movabsq $4294967296, %rax ## encoding: [0x48,0xb8,0x00,0x00,0x00,0x00,0x01,0x00,0x00,0x00] testq %rax, %rdi ## encoding: [0x48,0x85,0xf8] jne LBB0_2 ## encoding: [0x75,A] After: btq $32, %rdi ## encoding: [0x48,0x0f,0xba,0xe7,0x20] jb LBB0_2 ## encoding: [0x72,A] btq is usually slower than testq because it doesn't fuse with the jump, but here we're better off saving one register and a giant movabsq. llvm-svn: 145103

* Relax an invariant that block placement was trying to assert a bitChandler Carruth2011-11-232-3/+26
| | | | | | | | | | | further. This invariant just wasn't going to work in the face of unanalyzable branches; we need to be resillient to the phenomenon of chains poking into a loop and poking out of a loop. In fact, we already were, we just needed to not assert on it. This was found during a bootstrap with block placement turned on. llvm-svn: 145100
