Re: [PATCH 0/3][AArch64]More intrinsics/builtins improvements
Yeah, I agree that your approach is better. I missed this point. Thanks. Ah, sorry for the duplication of effort. And thanks for the heads-up about upcoming work! I don't think I have any plans for any of those others at the moment. In the case of vld1_dup, however, I'm going to argue that my approach (https://gcc.gnu.org/ml/gcc-patches/2014-11/msg01718.html) is better, in that a builtin is opaque (blocks optimization) for the midend, whereas gcc vector extensions (as in vdup_n_...) allows the midend to perform constant-folding, etc. Does that make sense? --Alan Yangfei (Felix) wrote: These three are logically independent, but all on a common theme, and I've tested them all together by bootstrapped + check-gcc on aarch64-none-elf cross-tested check-gcc on aarch64_be-none-elf Ok for trunk? Hi Alan, It seems that we are duplicating the work for the vld1_dup part. (Refer to my message: https://gcc.gnu.org/ml/gcc-patches/2014-11/msg01462.html) I have a plan to improve these intrinsics/builtins: vrsubhnX, vrsqrtX, vqrdmulX, vqmovX, vqdmulhqX, vqdmulhX, vpminX, vpmaxX, vpaddX, vpadaX vmvnX, vmulxX, vmovnX, vmlsX, vhsubX, vcvtX, vcopyX, vaddlvX, vabX, vfmX, vrecpeX, vcntX, vclsX And work for these intrinsics is in progress: vfmX, vrecpeX, vhsubX, vcntX, vclsX Please let me know if you guys want to work on any of them. Thanks.
