From bc8d688ff3c164fa717a0411e77621d590c87e3f Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Sun, 8 Jun 2014 18:24:14 -0700 Subject: [PATCH] tcg/optimize: Don't special case TCG_OPF_CALL_CLOBBER With the "old" ldst ops we didn't know the real width of the result of the load, but with the "new" ldst ops we do.
