From 213e823dc6bcd965eb212bc820bf0c5a3617103c Mon Sep 17 00:00:00 2001 From: James Cowgill Date: Thu, 26 Feb 2015 13:42:42 +0000 Subject: [PATCH] mips/mathops: remove 64-bit code GCC is perfectly happy generating optimized multiplication code on its own for 64-bit arches. GCC refuses to optimize the loongson code when in 32-bit mode, so I've left that.
