From ad8fb5537a7747187e92434dc096d3914472b51b Mon Sep 17 00:00:00 2001 From: Ralf Baechle Date: Tue, 22 Apr 2014 15:51:55 +0200 Subject: MIPS: math-emu: Replace DP_MBITS with DP_FBITS and SP_MBITS with SP_FBITS. Both were defined as 23 rsp. 52 though the mentissa is actually a bit more than the fraction.
