[Qemu-stable] [PATCH 14/60] fpu/softfloat.c: Return correctly signed values from uint64_to_float32 |
Date: |
Mon, 4 Feb 2013 14:40:24 +0400 |
From: Peter Maydell <address@hidden>
The uint64_to_float32() conversion function was incorrectly always
returning numbers with the sign bit set (ie negative numbers). Correct
this so we return positive numbers instead.
