https://bugs.kde.org/show_bug.cgi?id=357059 --- Comment #3 from Julian Seward --- If I had to guess, I would say that the Sept 2015 Intel docs are wrong, and that this instruction (cvtpi2ps) should behave the same way as cvtpi2pd does -- that is, a transition to MMX state

https://bugs.kde.org/show_bug.cgi?id=357059 --- Comment #2 from Julian Seward --- I'm not sure your test program is correct. The tag word is 16 bits at byte offsets 8 and 9, but the program tests fenv[9] and [10]. That said .. even after changing the 9 and 10 to 8 and 9, it
