Subject: [Qemu-devel] [PATCH 0/2] ARM: Detect FP tininess before rounding
Date: Tue, 12 Apr 2011 13:56:39 +0100 [thread overview]
Message-ID: <1302613001-17540-1-git-send-email-peter.maydell@linaro.org> (raw)
Softfloat supports two kinds of FP tininess detection: before and
after rounding (corresponding to the two behaviours permitted by
IEEE754). The ARM architecture mandates detection before rounding,
so set the flag appropriately. I had to add a setter function
for this, since there wasn't one already.
Peter Maydell (2):
softfloat: Add setter function for tininess detection mode
target-arm: Detect tininess before rounding for FP operations
