[Qemu-devel] [PATCH for-4.0 5/7] tcg/tcg.h: Remove GCC check for tcg_deb


From: Thomas Huth
Subject: [Qemu-devel] [PATCH for-4.0 5/7] tcg/tcg.h: Remove GCC check for tcg_debug_assert() macro
Date: Mon, 3 Dec 2018 15:05:35 +0100

Both GCC v4.8 and Clang v3.4 support (our minimum versions) support
__builtin_unreachable(), so we can remove the version check here now.
