From 55d0eac918321e0525f6e6491f36a80977e0d416 Mon Sep 17 00:00:00 2001 From: Mark Mendell Date: Thu, 6 Feb 2014 11:02:52 -0800 Subject: Support Direct Method/Type access for X86 Thumb generates code to optimize calls to methods within core.oat. Implement this for X86 as well, but take advantage of mov with 32 bit immediate and call relative with 32 bit immediate. Fix some incorrect return locations for long inlines.
