Subject: [Qemu-devel] [PATCH v3 0/4] softfloat: Fix division
Date: Thu, 4 Oct 2018 12:56:56 -0500 [thread overview]
Message-ID: <20181004175700.20847-1-richard.henderson@linaro.org> (raw)
Changes from v2:
* Add shift128Left. I had been using shortShift128Left,
with a shift of 64, which lead to undefined behaviour.
Which I suspect is exactly the Heisenbug Alex saw.
I did keep the R-b tags I had already applied.
