>From 6c1610661c3437768fb1485e909b11a731b8554b Mon Sep 17 00:00:00 2001 From: Naveen <[email protected]> Date: Wed, 28 Oct 2026 21:50:38 -0700 Subject: [PATCH] [libunwind] Fix -Wunused-function for hasPAuthLR in ra_sign_state_lr test hasPAuthLR() is a static function defined unconditionally in ra_sign_state_lr.pass.cpp but it is only called from checkHasPAuthLR() when _LIBUNWIND_HAVE_GETAUXVAL, LIBUNWIND_HAVE_ELF_AUX_INFO or LIBUNWIND_IS_BAREMETAL is defined. On targets where none of these macros are set (e.g. embedded AArch64 variants built against picolibc), the #else branch is taken and hasPAuthLR() is unused causing a -Werror,-Wunused-function build failure. Guard hasPAuthLR() with the same preprocessor conditions as its call-sites so it is only compiled when reachable.
