[Qemu-devel] [PATCH v3 0/4] softfloat: Fix division

[Richard Henderson]

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.
