Subject: readelf: mask unknown description data bytes.
X-Git-Url: http://git.efficios.com/?a=commitdiff_plain;h=178d871928b99112a39e0ca1284d6bbdde50ab6e;p=deliverable%2Fbinutils-gdb.git

readelf: mask unknown description data bytes.

When printing unknown note types, readelf prints the raw description
section byte-by-byte. However, it does not mask appropriately, e.g. it
prints the byte 'ba' as 'ffffffba'.

	* readelf.c (process_note): Mask unknown description data bytes.
