<!--LLVM PR SUMMARY COMMENT--> @llvm/pr-subscribers-clang Author: 袁銓嶽 (circYuan) <details> <summary>Changes</summary> This patch avoids adding redundant vcreate_v intrinsics to the RISCV IntrinsicList. Since vcreate_v uses LFixedLog2LMUL, I believe we can simply set Log2LMUL to the smallest value (-3) to prevent the creation of redundant vcreate_v instances with the same intrinsic name and prototype in the IntrinsicList when clang creates it. --- Full diff: https://github.com/llvm/llvm-project/pull/77889.diff 1 Files Affected: - (modified) clang/include/clang/Basic/riscv_vector.td (+5-3) ``````````diff diff --git a/clang/include/clang/Basic/riscv_vector.td b/clang/include/clang/Basic/riscv_vector.td index e7d78b03511fe9..1411d5375bdadd 100644 --- a/clang/include/clang/Basic/riscv_vector.td +++ b/clang/include/clang/Basic/riscv_vector.td @@ -2479,9 +2479,11 @@ let HasMasked = false, HasVL = false, IRName = "" in { } }] in { - defm : RVVNonTupleVCreateBuiltin<1, [0]>; - defm : RVVNonTupleVCreateBuiltin<2, [0, 1]>; - defm : RVVNonTupleVCreateBuiltin<3, [0, 1, 2]>; + let Log2LMUL = [-3] in { + defm : RVVNonTupleVCreateBuiltin<1, [0]>; + defm : RVVNonTupleVCreateBuiltin<2, [0, 1]>; + defm : RVVNonTupleVCreateBuiltin<3, [0, 1, 2]>; + } foreach nf = NFList in { let NF = nf in { `````````` </details> https://github.com/llvm/llvm-project/pull/77889 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
