Ulrich Drepper 103f02d372 1999-09-15 Ulrich Drepper <drepper@cygnus.com> 
* readelf.c (dynamic_segment_parisc_val): Print 0 for DLD_FLAGS if
	the value is zero.
	(process_symbol_table): Don't print histogram if hash table is empty.

1999-09-15  Ulrich Drepper  <drepper@cygnus.com>

	* readelf.c (get_parisc_dynamic_type): Handle DT_HP_GST_* values.

1999-09-02  Ulrich Drepper  <drepper@cygnus.com>

	* readelf.c (get_symbol_type): Add support for HPUX and PARISC
	specific symbol types.

	* readelf.c: Add HPUX and PARISC extensions to dynamic and program
	header table printing.

	* readelf.c (get_machine_flags): Add handling of PARISC.
