From 621644f290b6cd7e0f85677a85ae907a2d49ab43 Mon Sep 17 00:00:00 2001 From: Markus Volk Date: Wed, 16 Sep 2026 19:30:10 +0200 Subject: [PATCH] libjxl: do not build the SVE targets on tunes without SVE Whether Highway's SVE targets are built is decided by a compiler capability probe that compiles a function marked __attribute__((target("+sve"))). The attribute enables SVE for that function itself, so the probe succeeds on any aarch64 compiler no matter what the tune supports, and the guard meant to disable the targets never fires. On a tune without SVE this compiles code that can never run, and gcc 16 crashes while doing so: lib/jxl/enc_transforms-inl.h:799:1: internal compiler error: in simplify_gen_subreg_concatn, at lower-subreg.cc:744 Tie the targets to TUNE_FEATURES instead, which describes the machine rather than the compiler. 32 bit arm needs nothing: Highway gates the SVE targets on HWY_ARCH_ARM_A64, and the probe fails there anyway because arm_sve.h does not exist. Built for raspberrypi4-64 (cortexa72, no SVE) from a clean state, and checked that the x86-64 configuration is unchanged.
