If call result is in ST0 and it is not being passed to the caller's caller, then it is not safe to optimize the call into a sibcall since the call result has to be popped off the x87 stack. git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_27@99293 91177308-0d34-0410-b5e6-96231b3b80d8

Work around a bug in the openbsd assembler on i386, which doesn't support .quad correctly because it is "really really old". PR6528. Yet another reason the mc assembler should take over ;-) git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_27@98309 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-06Lower dynamic stack allocation on mingw32 to separate instruction.Anton Korobeynikov
We cannot use a normal call here since it has extra unmodelled side effects (it changes stack pointer). This should fix PR5292. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97884 91177308-0d34-0410-b5e6-96231b3b80d8

out the remainder of the calls that we should lower in some way and move the tests to the new correct directory. Fix up tests that are now optimized more than they were before by -instcombine. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97875 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-06Thumb1 epilogue code generation needs to take into account that callee-savedJim Grosbach
registers may be restored via a pop instruction, not just a tRestore. This fixes nightly test 471.omnetep for Thumb1. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97867 91177308-0d34-0410-b5e6-96231b3b80d8

Log: Transform @llvm.objectsize to integer if the argument is a result of malloc of known size.

2010-03-05Don't emit global symbols into the (__TEXT,__ustring) section on Darwin. ThisCharles Davis
is a workaround for <rdar://problem/7672401/> (which I filed). This let's us build Wine on Darwin, and it gets the Qt build there a little bit further (so Doug says). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97845 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-05Move SimplifyLibCalls's LibCall builders to a separate file so theyEric Christopher
can be used in more places. Add an argument for the TargetData that most of them need. Update for the getInt8PtrTy() change. Should be no functionality change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97844 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-05Better handling of dead super registers in LiveVariables. We used to do this:Jakob Stoklund Olesen
CALL ... %RAX<imp-def> ... [not using %RAX] %EAX = ..., %RAX<imp-use, kill> RET %EAX<imp-use,kill> Now we do this: CALL ... %RAX<imp-def, dead> ... [not using %RAX] %EAX = ... RET %EAX<imp-use,kill> By not artificially keeping %RAX alive, we lower register pressure a bit. The correct number of instructions for 2008-08-05-SpillerBug.ll is obviously 55, anybody can see that. Sheesh. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97838 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-05We don't really care about correct register liveness information after theJakob Stoklund Olesen
post-ra scheduler has run. Disable the verifier checks that late in the game. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97837 91177308-0d34-0410-b5e6-96231b3b80d8
