From 302fdde73f88fd958acfa18b670eed092eab21a0 Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Wed, 13 Mar 2013 13:40:43 -0700 Subject: tcg-arm: Use movi32 + blx for calls on v7 Work better with branch predition when we have movw+movt, as the size of the code is the same. Perhaps re-evaluate when we have a proper constant pool.
