[committed] Don't guard dump_die and dump_die calls with '#if DEVEL'



Hi,

I've used this pattern to enable the --devel-dump-dies code:
...
  #if DEVEL
  static int dump_dies_p;
  #else
  #define dump_dies_p 0
  #endif

  #if DEVEL
    if (dump_dies_p)
      dump_dies (...);
  #endif
...
but the second '#if DEVEL' is not required.

Without -DDEVEL, the call evaluates to:
...
    if (0)
      dump_dies (...);
...
which will be optimized out, as well as the dump_dies function itself.

Drop the '#if DEVEL' guard dump_dies and dump_dies calls.

Committed to trunk.

Thanks,
- Tom

Don't guard dump_die and dump_die calls with '#if DEVEL'

2019-11-05  Tom de Vries  <tdevries@suse.de>

	* dwz.c (dump_dies): Don't guard with '#if DEVEL'.
	(read_debug_info): Don't guard calls to dump_dies with '#if DEVEL'.
