2010-03-14tcg: add div/rem 32-bit helpersAurelien Jarno1-0/+24
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. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
