2008-01-15The type of the 'abort' node should be pointer type (becauseChris Lattner
it's a function pointer) not MVT::Other. This fixes builtin_trap lowering on ppc, alpha, ia64 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46018 91177308-0d34-0410-b5e6-96231b3b80d8

2008-01-14Simplify CallInst::hasByValArgument using a new method.Duncan Sands
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45974 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-14I noticed that the trampoline straightening transformation couldDuncan Sands
drop attributes on varargs call arguments. Also, it could generate invalid IR if the transformed call already had the 'nest' attribute somewhere (this can never happen for code coming from llvm-gcc, but it's a theoretical possibility). Fix both problems. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45973 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45964 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-14This test is now the same as byval-1.ll, so remove it.Duncan Sands
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45960 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-14Test that byval cannot be used with pointers toDuncan Sands
types with no size. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45959 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-14We now allow byval on fairly general pointer types.Duncan Sands
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45956 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-14Improve the FP stackifier to decide all on its own whether Chris Lattner
an instruction kills a register or not. This is cheap and easy to do now that instructions record this on their flags, and this eliminates the second pass of LiveVariables from the x86 backend. This speeds up a release llc by ~2.5%. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45955 91177308-0d34-0410-b5e6-96231b3b80d8

2008-01-14Fix the miscompilation of MiBench/consumer-lame that was exposed by Evan'sChris Lattner
byval work. This miscompilation is due to the program indexing an array out of range and us doing a transformation that broke this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45949 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-14The isNotSuitableForSRA property is now dead, don't compute it.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45948 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-14Change SRAGlobal to not depend on isNotSuitableForSRA, which makes it very Chris Lattner
difficult to understand the invariants. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45947 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-14Make the 'shrink global to bool' optimization more self contained, and thus Chris Lattner
easier to show that its safe. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45946 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-14Turn a memcpy from a double* into a load/store of double instead ofChris Lattner
a load/store of i64. The later prevents promotion/scalarrepl of the source and dest in many cases. This fixes the 300% performance regression of the byval stuff on stepanov_v1p2. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45945 91177308-0d34-0410-b5e6-96231b3b80d8

2008-01-13simplify some code. If we can infer alignment for source and dest that are Chris Lattner
greater than memcpy alignment, and if we lower to load/store, use the best alignment info we have. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45943 91177308-0d34-0410-b5e6-96231b3b80d8
