Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org --- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> --- That is not a bug, DW_TAG_call_site_parameter is emitted only when it has something relevant to say (like, what value has been passed). If it isn't known how to reconstruct the value or if the compiler is unable to track the value passed to it, it can omit it.
