2012-11-15[reg scavenger] Fix the isUsed/isAliasUsed functions so as to not report a falseChad Rosier
positive. In this particular case, R6 was being spilled by the register scavenger when it was in fact dead. The isUsed function reported R6 as used because the R6_R7 alias was reserved (due to the fact that we've reserved R7 as the FP). The solution is to only check if the original register (i.e., R6) isReserved and not the aliases. The aliases are only checked to make sure they're available. The test case is derived from one of the nightly tester benchmarks and is rather intractable and difficult to reproduce, so I haven't included it. rdar://12592448 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168054 91177308-0d34-0410-b5e6-96231b3b80d8

2012-11-15Make GlobalOpt be conservative with TLS variables (PR14309)Hans Wennborg
For global variables that get the same value stored into them everywhere, GlobalOpt will replace them with a constant. The problem is that a thread-local GlobalVariable looks like one value (the address of the TLS var), but is different between threads. This patch introduces Constant::isThreadDependent() which returns true for thread-local variables and constants which depend on them (e.g. a GEP into a thread-local array), and teaches GlobalOpt not to track such values. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168037 91177308-0d34-0410-b5e6-96231b3b80d8

2012-11-15Fix a crash observed by Shuxin Yang. The issue here is that LinearizeExprTree,Duncan Sands
the utility for extracting a chain of operations from the IR, thought that it might as well combine any constants it came across (rather than just returning them along with everything else). On the other hand, the factorization code would like to see the individual constants (this is quite reasonable: it is much easier to pull a factor of 3 out of 2*3 than it is to pull it out of 6; you may think 6/3 isn't so hard, but due to overflow it's not as easy to undo multiplications of constants as it may at first appear). This patch therefore makes LinearizeExprTree stupider: it now leaves optimizing to the optimization part of reassociate, and sticks to just analysing the IR. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168035 91177308-0d34-0410-b5e6-96231b3b80d8
