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

...found that none of it works even on x86, and the current > handling of the half conversion SDNodes seem to rely on ARM specific > assumptions   Just for the record, since revision 212293 (committed only five days ago), the x86 backend supports float half conversions. On x86, if the target has F16C, there are ISel patterns to map float-half conversions to specific instructions. If there is no F16C support, then the backend expands float-half conversions into runtime library calls.   Cheers, Andrea -------------- next part -------------- An HTML attachment was scrubbed...
