Subject: translate-all: define and use DEBUG_TB_INVALIDATE_GATE
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=dae9e03aed8e652f5dce2e5cab05dff83aa193b8;p=qemu.git

translate-all: define and use DEBUG_TB_INVALIDATE_GATE

This gets rid of an ifdef check while ensuring that the debug code
is compiled, which prevents bit rot.
