Subject: tcg/tcg.h: Remove GCC check for tcg_debug_assert() macro
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=6fa2cef205a60b5c5c3b058f53852416b885c455;p=qmiga%2Fqemu.git

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.
