X-Git-Tag: VALGRIND_3_25_0~77
X-Git-Url: http://git.ipfire.org/gitweb/gitweb.cgi?a=commitdiff_plain;h=ddcb3aa3ed3188cd28c193225245a76e928b850b;p=thirdparty%2Fvalgrind.git

filter_gdb.in: filter out __libc_do_syscall

On i386 and armhf __libc_do_syscall might be used to invoke a syscall.
Replace __libc_do_syscall with "in syscall ..." and filter out
possible extra (assembly) source file lines containing
libc-do-syscall.S from the gdb output.
