Alpha call dummy address reads:
CORE_ADDR entry;
struct minimal_symbol *sym;
entry = entry_point_address ();
if (entry != 0)
return entry;
sym = lookup_minimal_symbol ("_Prelude", NULL, symfile_objfile);
unless something really weird is happening, entry_point_address will succeed making the remaining code dead.

* alpha-tdep.c: Gobs of changes (many imported from mips-tdep) to
improve remote debugging efficiency. Also fixed problems with
doing function calls for programs with no entry points.
* infcmd.c (run_stack_dummy): Use CALL_DUMMY_ADDRESS instead of
entry_point_address.
* inferior.h (PC_IN_CALL_DUMMY): ditto.
* mdebugread.c (parse_symbol, parse_procedure, parse_external,
parse_lines): Pass section_offsets info to these routines so that
we can relocate symbol table entries upon readin.
* (psymtab_to_symtab_1): Set symtab->primary to tell
objfile_relocate to do relocations for our symbols.
* (ecoff_relocate_efi): New routine to relocate adr field of PDRs
(which hang off of the symbol table).
* Use prim_record_minimal_symbols_and_info instead of
prim_record_minimal_symbols to supply section info to make minimal
symbol relocations work.
* minsyms.c (prim_record_minimal_symbols_and_info): If section is
-1, try to deduce it from ms_type.
* objfiles.c (objfile_relocate): Use ALL_OBJFILE_SYMTABS where
appropriate. Handle relocation of MIPS_EFI symbols special. Also,
add code to relocate objfile->sections data structure.
* remote.c (get_offsets): Use new protocol message to acquire
section offsets from the target.
* (remote_wait): Get rid of relocation stuff. That's all handled
by objfile_relocate now.
* config/alpha/alpha-nw.mt (TM_FILE): Use tm-alphanw.h.
* config/alpha/tm-alpha.h: Define CALL_DUMMY_ADDRESS, and
VM_MIN_ADDRESS.
* config/alpha/tm-alphanw.h: DECR_PC_AFTER_BREAK=0, VM_MIN_ADDRESS=0.
there is now a better way of handling functions with no entry point.
