Implement generic __clc_fma with __builtin_elementwise_fma for all targets except for r600. Add --spirv-ext=+SPV_KHR_fma flag to SPIR-V generation. SPIR-V target supports @llvm.fma since SPV_KHR_fma was implemented in llvm-spirv (https://github.com/KhronosGroup/SPIRV-LLVM-Translator/pull/3467) and SPIR-V backend (8f8dfbf8c9f0). This PR assumes SPIR-V consumer with modern hardware supports fma. >From 392c0e32ea6f7600e9cba4c59f678cc5abef89ce Mon Sep 17 00:00:00 2001 From: Wenju He <[email protected]> Date: Mon, 2 Feb 2026 05:55:59 +0100 Subject: [PATCH] [libclc] Only use software fma for r600 target Implement generic __clc_fma with __builtin_elementwise_fma for all targets except for r600.
