2007-04-12Make sure intrinsics that are lowered to functions make the function weakReid Spencer
linkage so we only end up with one of them in a program. These are, after all overloaded and templatish in nature. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@35956 91177308-0d34-0410-b5e6-96231b3b80d8
2007-04-12Provide support for intrinsics that lower themselves to a function body.Reid Spencer
This can happen for intrinsics that are overloaded. In such cases it is necessary to emit a function prototype before the body of the function that calls the intrinsic and to ensure we don't emit it multiple times. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@35954 91177308-0d34-0410-b5e6-96231b3b80d8

2007-04-12the result of an inline asm copy can be an arbitrary VT that the registerChris Lattner
class supports. In the case of vectors, this means we often get the wrong type (e.g. we get v4f32 instead of v8i16). Make sure to convert the vector result to the right type.
