--- Comment #6 from Peter Bergner <bergner at gcc dot gnu.org> ---
I have a patch I'm testing. The problem is that rs6000_set_current_function()
is not clearing the rs6000_previous_fndecl cache correctly when it needs to.
With the test case, we notice that rs6000_previous_fndecl is set (when it
shouldn't be) and we end up restoring options from it which incorrectly disable
HW sqrt leading to the ICE.
The current code is also a rats nest and hard to read/understand, so the patch
I'm testing is modeled on s390's version of the same function which is much
cleaner and correctly clears out the rs6000_previous_fndecl when it needs to.
