>From 648bfd77d48c395ae81a1d28fa6d925e1e75c02a Mon Sep 17 00:00:00 2001 From: Srinivasa Ravi <sriniva...@nvidia.com> Date: Wed, 5 Mar 2025 12:35:39 +0530 Subject: [PATCH] [NVPTX] Add intrinsics for cvt .f6x2 and .ue8m0x2 variants This change adds NVVM intrinsics and clang builtins for the cvt instruction variants of types .e2m3x2, .e3m2x2, and .ue8m0x2 introduced in PTX 8.6 for `sm_100a`, `sm_101a`, and `sm_120a`. Tests are added in `NVPTX/convert-sm1XXa.ll` and `clang/test/CodeGen/builtins-nvptx.c` and verified through ptxas 12.8.0.
