2012-02-05Teach GlobalOpt to handle atomic accesses to globals.Nick Lewycky
* Most of the transforms come through intact by having each transformed load or store copy the ordering and synchronization scope of the original. * The transform that turns a global only accessed in main() into an alloca (since main is non-recursive) with a store of the initial value uses an unordered store, since it's guaranteed to be the first thing to happen in main. (Threads may have started before main (!) but they can't have the address of a function local before the point in the entry block we insert our code.) * The heap-SRoA transforms are disabled in the face of atomic operations. This can probably be improved; it seems odd to have atomic accesses to an alloca that doesn't have its address taken. AnalyzeGlobal keeps track of the strongest ordering found in any use of the global. This is more information than we need right now, but it's cheap to compute and likely to be useful. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149847 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-05Reduce the number of dom queries made by GVN's conditional propagationDuncan Sands
logic by half: isOnlyReachableViaThisEdge was trying to be clever and handle the case of a branch to a basic block which is contained in a loop. This costs a domtree lookup and is completely useless due to GVN's position in the pass pipeline: all loops have preheaders at this point, which means it is enough for isOnlyReachableViaThisEdge to check that Dst has only one predecessor. (I checked this theoretical argument by running over the entire nightly testsuite, and indeed it is so!). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149838 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-05reapply the patches reverted in r149470 that reenable ConstantDataArray,Chris Lattner
but with a critical fix to the SelectionDAG code that optimizes copies from strings into immediate stores: the previous code was stopping reading string data at the first nul. Address this by adding a new argument to llvm::getConstantStringInfo, preserving the behavior before the patch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149800 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-05Remove most of the intrinsics for XOP VPCMOV instruction. They all aliased ↵Craig Topper
to the same instruction with different types. This would be better accomplished with casts in the not yet created xopintrin.h header file. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149795 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-04Modified the Enhanced Disassembler to create andSean Callanan
cache disassemblers according to the string value of the target triple, not according to the enum of the triple CPU. The reason for this is that certain attributes of the instruction set are not reflected in the enum, but only in the string. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149773 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-04Drop the REDEF_BY_EC VNInfo flag.Jakob Stoklund Olesen
A live range that has an early clobber tied redef now looks like a normal tied redef, except the early clobber def uses the early clobber slot. This is enough to handle any strange interference problems. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149769 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-04Correctly terminate a physreg redefined by an early clobber.Jakob Stoklund Olesen
I don't have a test that fails because of this, but a test case like CodeGen/X86/2009-12-01-EarlyClobberBug.ll exposes the problem. EAX is redefined by a tied early clobber operand on inline asm, and the live range should look like this: %EAX,inf = [48r,64e:0)[64e,80r:1) 0@48r 1@64e Previously, the two values got merged: %EAX,inf = [48r,80r:0) 0@48r With this bug fixed, the REDEF_BY_EC VNInfo flag is no longer needed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149768 91177308-0d34-0410-b5e6-96231b3b80d8
