Hi Alexander. I just verified that the patch fixes the make check-brig
regression here. Are you going to post this to ML for review or how shall we
proceed?

[Bug libgcc/67624] New: arm/fp16.c __gnu_f2h_internal has wrong pattern for INF/NAN

[pekka.jaaskelainen at parmance dot com]

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=67624

Bug ID: 67624
   Summary: arm/fp16.c __gnu_f2h_internal has wrong pattern for
INF/NAN
   Product: gcc
   Version: 4.9.1
Status: UNCONFIRMED
  Severity: major
  Priority: P3
 Component: libgcc
  Assignee: unassigned at gcc dot gnu.org
  Reporter: pekka.jaaskelainen at parmance dot com
  Target Milestone: ---

I believe the f2h conversion routine uses wrong mask for INF/NAN in the early
shortcut. It seems to be the case also in the gcc HEAD.

This should fix it:
