Subject: target-ppc: Use correct precision for FPRF setting
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=9aeae8e16e6153aa2f28272dc75904c94f0e8cac;p=qemu.git

target-ppc: Use correct precision for FPRF setting

Use correct FP precision when setting FPRF in FP conversion helpers
instead of always assuming float64 precision.
