Subject: HP-PA: use is_whitespace()
X-Git-Tag: binutils-2_45~1746
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d99c62deef0ea5d579486448716022e820c6c377;p=thirdparty%2Fbinutils-gdb.git

HP-PA: use is_whitespace()

Convert open-coded checks. At the same time use is_end_of_stmt() instead
of an open-coded check in adjacent code.
