            Bug ID: 67424
           Summary: libcilkcrts fails to build on NetBSD
           Product: gcc
           Version: 5.2.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: other
          Assignee: unassigned at gcc dot gnu.org
          Reporter: gcc at rkeene dot org
  Target Milestone: ---

GCC 5.2.0 fails to build a compiler for NetBSD on x86_64 by default.


This is because libcilkrts/configure.tgt does not return unsupported for NetBSD
on x86_64, but libcilkrts/runtime/os-unix.c #ifdefs return an #error directive
for NetBSD.

support netbsd in libcilkrts/runtime/os-unix.c

I'm testing this

That allows the bootstrap to complete, but all the cilk+ tests fail:

/home/jwakely/gcc/5/x86_64-unknown-netbsd5.1/bin/ld: ./reduction-3.exe: hidden
