Unnecessary spill/fill issue
Hi, I am using mcjit in llvm 3.6 to jit kernels to x86 avx2. I've noticed
some inefficient use of the stack around constant vectors. In one example,
I have code that computes a series of constant vectors at compile time.
Each vector has a single use. In the final asm, I see a series of spills at
the top of the function of all the constant vectors immediately to stack,
then each use references
