From 5f8741860d465410bfed495dbb5f794590d338da Mon Sep 17 00:00:00 2001 From: Mark Mendell Date: Wed, 4 Mar 2015 15:42:45 -0500 Subject: [optimizing] Use callee-save registers for x86 Add ESI, EDI, EBP to available registers for non-baseline mode. Ensure that they aren't used when byte addressible registers are needed.
