Changes to support alpha OSF/1 in native mode.
* alpha-nat.c, alpha-tdep.c, config/alpha/alpha-osf1.mt,
config/alpha/nm-alpha.h, config/alpha/tm-alpha.h, osfsolib.c:
New files.
* Makefile.in: Add new files and dependencies.
* configure.in: Add alpha target.
* config/alpha/alpha-osf1.mh (NATDEPFILES): Add osfsolib.o
* config/alpha/alpha-osf1.mh (MH_CFLAGS): Remove, we can handle
shared libraries now.
* config/alpha/xm-alpha.h: Cleanup, get MAKEVA_* defines right.
* defs.h (CORE_ADDR): Make its type overridable via CORE_ADDR_TYPE,
provide `unsigned int' default.
* breakpoint.c (breakpoint_auto_delete): Delete only if we really
stopped for the breakpoint.
* stabsread.c, stabsread.h (define_symbol): Change valu parameter
to a CORE_ADDR.
* stabsread.c (read_range_type): Handle the case where the lower
bound overflows and the upper doesn't and the range is legal.
* infrun.c (resume): Do not step a breakpoint instruction if
CANNOT_STEP_BREAKPOINT is defined.
* inferior.h (CALL_DUMMY_LOCATION): New variant AT_ENTRY_POINT.
Now that we have the bp_call_dummy breakpoint the call dummy code
is no longer needed. PUSH_DUMMY_FRAME, PUSH_ARGUMENTS and
FIX_CALL_DUMMY can be used to set up everything for the dummy.
The breakpoint for the dummy is set at the entry point and thats it.
* blockframe.c (inside_entry_file, inside_entry_func): Do not stop
backtraces if pc is in the call dummy at the entry point.
* infcmd.c (run_stack_dummy): Handle AT_ENTRY_POINT case. Use
the expected breakpoint pc when setting up the frame for
set_momentary_breakpoint.
* symfile.c (entry_point_address): New function for AT_ENTRY_POINT
support.
* valops.c (call_function_by_hand): Handle AT_ENTRY_POINT case.
