From 24b0d29ce73ddecd41ac08d3b2f6090f23fc3bfc Mon Sep 17 00:00:00 2001 From: Cursor Agent Date: Wed, 30 Sep 2026 11:40:18 +0000 Subject: [PATCH] -remove support of HVX extension (Hexagon platform). Drop the remaining HVX code path, including HistogramConditional, SIMD_HVX macros, SimdCpuInfoHvx, test hooks, and the performance report column. Remove the Hexagon CMake target, GitHub Actions job, and Visual Studio Hvx project. Document the removal in the 7.2.166 release notes.
