            Bug ID: 59091
           Summary: __builtin_trap calls abort for arm-linux-gnueabi
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: pinskia at gcc dot gnu.org
            Target: arm-linux-gnueabi

Right now __builtin_trap calls abort on arm-linux-gnueabi which causes glibc
fail to build as that brings in lots of dependencies.  The arm back-end should
implement a "trap" pattern.

See https://sourceware.org/ml/libc-alpha/2013-11/msg00291.html for more
information on the glibc failure.

Mark Mitchell proposed a patch some time back, not sure why it didn't get
installed:

We'll look into fixing this for 4.9. The one thing appearing to be missing
there is a blessing of a bit pattern and that's probably why it fell between
the cracks.
