I think the crucial part about the option is that it starts with -fdump-*; same result for -fdump-parse-tree while all other options seem to work. Grepping for fdump finds in *opt: common.opt:fdump- common.opt:fdump-final-insns= common.opt:fdump-noaddr common.opt:fdump-unnumbered common.opt:fdump-unnumbered-links fortran/lang.opt:fdump-core fortran/lang.opt:fdump-parse-tree -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42675
