/* GDB expects the absolute function start address for the
procedure descriptor in e->pdr.adr.
As the address in the procedure descriptor is usually relative,
we would have to relocate e->pdr.adr with cur_fdr->adr and
ANOFFSET (pst->section_offsets, SECT_OFF_TEXT).
Unfortunately cur_fdr->adr and e->pdr.adr are both absolute
in shared libraries on some systems, and on other systems
e->pdr.adr is sometimes offset by a bogus value.
To work around these problems, we replace e->pdr.adr with
the start address of the function. */
