llvm-mirror/test/CodeGen/AMDGPU/strict_fma.f64.ll
Baptiste Saleil c4a674e21e [AMDGPU] Experiments show that the GCNRegBankReassign pass significantly impacts
the compilation time and there is no case for which we see any improvement in
performance. This patch removes this pass and its associated test cases from
the tree.
