[LLVMdev] __fp16 suport in llvm back-end
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]
