[Qemu-devel] [PATCH v2 16/22] target-mips: add new Floating Point instructions

2014-06-11 Thread Leon Alrae
In terms of encoding MIPS32R6 MIN.fmt, MAX.fmt, MINA.fmt, MAXA.fmt replaced MIPS-3D RECIP1, RECIP2, RSQRT1, RSQRT2 instructions. In R6 all Floating Point instructions are supposed to be IEEE-2008 compliant i.e. FIR.HAS2008 always 1. However, QEMU softfloat for MIPS has not been updated yet. Signe
