...I suppose, except for the fact that it hasn't taken the lack of target support for half-precision arithmetic into account yet. That will happen in the selection DAG. The assembly code generated looks like this (with my annotations): f: # @f # %bb.0: vcvtps2ph xmm1, xmm1, 4 # Convert argument 1 from single to half vcvtph2ps xmm1, xmm1 # Convert argument 1 back to single vcvtps2ph xmm0, xmm0, 4 # Convert argument 0 from single to half vcvtph2ps xmm0, xmm0...

Hi, all: I am trying to test half float point support in llvm, I found clang can generate bitcode for __fp16, while llc can't generate code for it, the error message is like this LLVM ERROR: Cannot select: 0x26a68e0: i16 = fp32_to_fp16 0x26a67d8 [ORD=2] [ID=4] 0x26a67d8: f32,ch = CopyFromReg 0x2693060, 0x26a66d0 [ORD=2] [ID=3] 0x26a66d0: f32 = Register %vreg1 [ID=1] In function: test
