From 3b6dac34161bc0a342336072643c2f6d17e0ec45 Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Wed, 2 Jun 2010 17:26:55 -0700 Subject: tcg: Add TYPE parameter to tcg_out_mov. Mirror tcg_out_movi in having a TYPE parameter. This allows x86_64 to perform the move at the proper width, which may elide a REX prefix. Introduce a TCG_TYPE_REG enumerator to represent the "native width" of the host register, and to distinguish the usage from "pointer data" as represented by the existing TCG_TYPE_PTR. Update all targets to match.
