New Revision: 214651
URL: http://svn.freebsd.org/changeset/base/214651
Log:
Fix reading of .debug_line on MIPS64, big-endian:
read_initial_length detects pointer size by checking first
4 bytes of .debug_line and stores it in struct comp_unit_head *
passed to it as second argument. By passing NULL to a
read_initial_length we ignore actual pointer size (8 bytes) and
use default (4 bytes) which results in wrong offsets of header fields.
