From d1e321b82a021c2e86d204af870356bc72b22546 Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Mon, 24 Sep 2012 14:21:41 -0700 Subject: [PATCH] tcg: Add tcg_high_cond The table that was recently added for hppa is generally usable. And with the renumbering of the TCG_COND constants it's not too difficult to compute rather than have a table.
