Subject: tcg: Don't make exitreq flag a local temporary
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=a4960ef34829c355fdf25b8ee6b869c92393e366;p=qemu.git

tcg: Don't make exitreq flag a local temporary

The value is not actually live across basic blocks, so there's no
need for the local property.  This eliminates storing the temporary
to its home location at the branch.
