-Wpointer-sign: dwarf2-frame.c: Pass unsigned variable to safe_read_uleb128.
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. gdb/ 2013-04-19 Pedro Alves <palves@redhat.com> * dwarf2-frame.c (execute_cfa_program): Make 'bytes_read' local unsigned. Pass 'tmp' to safe_read_uleb128 instead of the signed 'offset', and adjust.
