Some more issues found by Coverity scanner.lto-cgraph.c: The code seems to be unused, besides, it's a zero-trip loop as parm_num is set to 0 and then checked non nonzeroness.
lto-opts: The check whether first_p is non NULL is always false: All calls have a variable ref as argument - and first_p is unconditionally dereferenced.
lto_obj_file_open: One could check additionally check "lo" is NULL, but that has then to be directly after the XCNEW as already lto_file_init dereferences "lo".
