From 56a6473339dbd2e908cf8c6f2856d5de2bf8d15b Mon Sep 17 00:00:00 2001 From: Ralf Baechle Date: Wed, 30 Apr 2014 11:21:55 +0200 Subject: MIPS: math-emu: Switch to using the MIPS rounding modes. Previously math-emu was using the IEEE-754 constants internally. These were differing by having the constants for rounding to +/- infinity switched, so a conversion was necessary. This would be entirely avoidable if the MIPS constants were used throughout, so get rid of the bloat.
