--- Comment #2 from Josh Stone <jistone at redhat dot com> ---
I found that dwarf_wrappers.cxx dwarf_type_name doesn't handle
DW_TAG_subroutine_type, and it treats unknowns as "void", so the function
pointer type becomes "void*". That can be improved, but we'll also need to be
a bit more clever about the declaration since function pointer names are in the
middle of the type. We can probably just write a typedef for each argument to
use in STP_TRACE_ENTER.
