From 6fa2cef205a60b5c5c3b058f53852416b885c455 Mon Sep 17 00:00:00 2001 From: Thomas Huth Date: Mon, 3 Dec 2018 13:48:19 +0100 Subject: [PATCH] tcg/tcg.h: Remove GCC check for tcg_debug_assert() macro Both GCC v4.8 and Clang v3.4 (our minimum versions) support __builtin_unreachable(), so we can remove the version check here now.
