Subject: [Qemu-devel] [PATCH for-2.12] fpu: Fix rounding mode for floatN_to_uintM_round_to_zero
Date: Tue, 10 Apr 2018 15:59:12 +1000	[thread overview]
Message-ID: <20180410055912.934-1-richard.henderson@linaro.org> (raw)

We incorrectly passed in the current rounding mode
instead of float_round_to_zero.

Signed-off-by: Richard Henderson <richard.henderson@linaro.org>

Found while runnning SVE RISU tests; it should be visible with the
right set of inputs to AdvSIMD RISU tests.
