Description (last modified by Gedare Bloom)

We should wait with the RTEMS 4.10 release until we have a workaround or fix for this GCC bug:

​http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44091

The bug vanishes if you change the optimization level or use ARM code instead of Thumb code. Who knows if this really prevents such failures?

Resolution: → fixed
Status: new → closed

It seems that -fno-schedule-insns2 is a workaround. At least the test case generates valid code after disabling this optimization.
