Truncation is what distinguishes this from `_mm_cvtpd_epi32` so I think it is necessary? That information used to be in the second paragraph, I shortened it and moved it up to the first paragraph, to make that difference more obvious. Behavior on overflow was added to the second paragraph. Do you have a different suggestion for how to organize this information? https://github.com/llvm/llvm-project/pull/83447 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
