[Qemu-devel] [PATCH v3] target/mips: Fix minor bug in FPU

[Mateja Marjanovic]

From: Mateja Marjanovic <address@hidden>

The if-else statement indicates if the system conforms to
IEEE 754-1985 or IEEE 754-2008, and it has different
behaviour depending on that.

v3:
 - In case of IEEE 754-1985, return the default-NaN and raise
   floating point exception 'Invalid Operation' [1](page 349, 350), when infzero
   is present.
 - In case of IEEE 754-2008, return the input value 'c' [2](page 51) and
   raise floating point exception 'Invalid Operation' [1](page 349, 350),
   when infzero is present.
 - Comments were modified
