2008-01-15Rename CCIfStruct to CCIfByVal and CCStructAssign to CCPassByVal. Remove ↵Evan Cheng

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

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

2008-01-14Make the 'shrink global to bool' optimization more self contained, and thus Chris Lattner

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
