https://github.com/pogo59 commented: Thanks for the heads-up @RKSimon I've made suggestions for consistency with existing practice in emmintrin.h which I've adopted in the latest revision to #83316. I'm unsure how replacing a function declaration with an \fn directive will play with our documentation tooling. But we can figure that out later. https://github.com/llvm/llvm-project/pull/84136 ___ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits

But we can figure that out later. I've committed your suggestions.
