From eae13eae9d6499e81cd77bcd9e13f7bcb31b5577 Mon Sep 17 00:00:00 2001 From: James Cowgill Date: Thu, 5 Mar 2015 17:40:14 +0000 Subject: configure, mips: remove MIPS32R2, merging it with MIPSFPU There are no independant uses of mips32r2 instructions except for the FPU parts. Due to the heavy use of mips32r2 specifc fpu extensions, I am guessing the original author intended MIPSFPU to imply MIPS32R2 anyway. Since these fpu instructions are available on mips64 (non-r2), enable them there as well. Also remove the last occurence of HAVE_MIPS32R2 (which is coupled to HAVE_MIPSFPU anyway). mips32r2 is left in the list of options form compatability so that using --disable-mips32r2 doesn't break anything.
