    • [ARM][Testsuite]make dump_stack function call conditional in cold-lc.c · ef0e3441 
      After r249013, die () and dump_stack () are both in cold section. This makes
the compiler generate bl instruction for the function call, instead of
honoring the -mlong-calls option.

This patch changes the dump_stack function call conditional, which fixes the
regression.

gcc/testsuite/

	* gcc.target/arm/cold-lc.c: Update coding style, call dump_stack
	conditionally.

    If there is no function name, the traceback is generally
    uninformative.  In earlier versions we did not show such frames.
    Restore that behavior.  These frames can be seen with GOTRACEBACK=system.
