Message-ID: <20190505102520.GA5031@delia> MIME-Version: 1.0 Content-Disposition: inline User-Agent: Mutt/1.10.1 (2018-07-13) X-IsSubscribed: yes Hi, DW_AT_main_subprogram is supported in normal mode in read_partial_die, but not in -readnow mode. Fix this by adding support for DW_AT_main_subprogram in read_func_scope. Tested on x86_64-linux with native and RFC target board readnow ( https://sourceware.org/ml/gdb-patches/2019-05/msg00073.html ). OK for trunk?
