--- Comment #1 from avieira at gcc dot gnu.org --- OK I think I assigned the blame to the wrong function, I think it is the responsibility of 'is_indirect_tailcall_p' to catch this. Though I believe the last time it is called during the postreload pass, the call rtx still has a symbolref in it and only later in the pass is it replaced with a register. Too late for this function to catch it and after that 'reload_completed' is set to true and 'arm_get_frame_offsets' only returns the precomputed offsets. I have a workaround where I add a use clause to the sibling patterns, which seems to work, but I am not entirely sure why it works and I am not sure it is the right approach either.
