You can use contrib/gcc-changelog/git_check_commit.py to validate them. I don't see "Signed-off-by" tags in the patches. Have you either filed a copyright assignment with the FSF, or can you please add the tags to certify that you wrote the patches and can contribute them, see: https://gcc.gnu.org/contribute.html#legal https://gcc.gnu.org/dco.html [...snip...] > +proc jit-check-debug-info { obj_file cmds match } { > + verbose "Checking debug info for $obj_file with match: $match" > + > + if { [catch {exec gdb -v} fid] } { > + verbose "No gdb seems to be in path. Can't check debug info. Reporting expected fail." > + xfail "No gdb seems to be in path. Can't check debug info" I think this should be "unsupported" rather than "xfail".

See: https://gcc.gnu.org/onlinedocs/jit/topics/locations.html#faking-it OK otherwise. Thanks Dave
