2016-02-09tcg: Respect highwater in tcg_out_tb_finalizeRichard Henderson1-1/+2
Undo the workaround at b17a6d3390f87620735f7efb03bb1c96682ff449. If there are lots of memory operations in a TB, the slow path code can exceed the highwater reservation. Add a check within the loop.

2013-10-10tcg: Add tcg-be-null.hRichard Henderson1-0/+43
This is a no-op backend data implementation, for those targets that are not currently using the load/store optimization path. This is prepatory to always requiring these functions in all backends. Signed-off-by: Richard Henderson <rth@twiddle.net>
