[PATCH] D106301: [OpenMP] Disable trap before unreachable for OpenMP device jobs

[Johannes Doerfert via Phabricator via cfe-commits]

jdoerfert added a comment.

As an example, often end up with code like this right now:

    %26 = load i32, i32* addrspacecast (i32 addrspace(3)* @execution_param to i32*), align 4, !dbg !39, !tbaa !27
    %and.i13.i.i = and i32 %26, 4, !dbg !39
    %cmp.i14.not.i.i = icmp eq i32 %and.i13.i.i, 0, !dbg !39
    br i1 %cmp.i14.not.i.i, label %if.end.i129.i.i, label %__kmpc_parallel_51.exit.i, !dbg !39
  
  if.end.i129.i.i:                                  ; preds = %_Z16DecParallelLevelbj.exit.i.i
    tail call void @llvm.trap() #10, !dbg !39
    unreachable, !dbg !39

which could be:

  br label %__kmpc_parallel_51.exit.i, !dbg !39
