Subject: [PATCH 22/26] -Wpointer-sign: dwarf2-frame.c: Pass unsigned variable to safe_read_uleb128.
Date: Fri, 12 Apr 2013 09:54:00 -0000 [thread overview]
Message-ID: <20130411230137.16791.28220.stgit@brno.lan> (raw)
In-Reply-To: <20130411225847.16791.29283.stgit@brno.lan>
The 'bytes_read' change should be obvious. As for the other hunk,
we're passing the address of the signed 'offset' to safe_read_uleb128,
which expects unsigned. Fix it by passing the address of the unsigned
'utmp' instead, like already done on other spots in the file.

* dwarf2-frame.c (execute_cfa_program): Make 'bytes_read' local
unsigned. Pass 'tmp' to safe_read_uleb128 instead of the signed
'offset', and adjust.
