From 31d6655100cd54a8c081e04349661c0f08117e66 Mon Sep 17 00:00:00 2001 From: Aurelien Jarno Date: Tue, 2 Mar 2010 23:16:36 +0100 Subject: tcg: add div/rem 32-bit helpers Some targets like ARM would benefit to use 32-bit helpers for div/rem/divu/remu. Create a #define for div2 so that targets can select between div, div2 and helper implementation. Use the helper version if none of the #define are present.
