From 1fa97971e0ff25276f6e5d71ce145dc1904993c6 Mon Sep 17 00:00:00 2001 From: Thomas Munro Date: Fri, 28 Nov 2025 14:19:09 +1300 Subject: [PATCH 2/6] jit: Fix jit_profiling_support when not available. On LLVM libraries built without LLVM_USE_PERF, which probably means all non-Linux systems, LLVMCreatePerfJITEventListener() is a dummy function that returns NULL. Silently ignore the option, avoiding an assertion failure or segmentation fault inside LLVM. LLVMCreateGDBRegistrationListener() is called similarly but is always available so needs no guard.
