Add procfs support for Alpha OSF/1-2.x.
* config/alpha/nm-osf.h: Renamed from nm-alpha.h, generic
OSF/1 native support.
* config/alpha/alpha-osf1.mh (NAT_FILE): Changed accordingly.
(MUNCH_DEFINE): Removed.
* config/alpha/alpha-osf2.mh, config/alpha/nm-osf2.h: New files
for procfs support.
* configure.in (alpha-dec-osf*): Use alpha-osf2.mh for OSF/1
release 2.x and higher, else alpha-osf1.mh, as the procfs support
in release 1.x is incomplete.
* Makefile.in (ALLCONFIG): Add config/alpha/alpha-osf2.mh.
* alpha-nat.c (supply_gregset, fill_gregset, supply_fpgregset,
fill_fpgregset): New routines for procfs support.
* inftarg.c (_initialize_inftarg): Don't add ptrace support
if we have an optional procfs and /proc is accessible.
* procfs.c: Include sys/fault.h and sys/syscall.h before
including sys/procfs.h.
(unconditionally_kill_inferior): If PROCFS_NEED_PIOCSSIG_FOR_KILL
is defined, additionally perform a PIOCSSIG to really terminate
the inferior.
(create_procinfo): Always return a result.
(create_procinfo, do_attach): Don't trace T_IFAULT faults if
PROCFS_DONT_TRACE_IFAULT is defined.
(procfs_init_inferior): Use START_INFERIOR_TRAPS_EXPECTED as
argument to startup_inferior if it is defined.
(proc_set_exec_trap): If PIOCSSPCACT is defined, use it instead
of tracing exits from exec system calls. Needed for the user level
loader under Alpha OSF/1.
(do_detach): Clear any pending signal if we want to detach from
a process without a signal.
(set_proc_siginfo): If PROCFS_DONT_PIOCSSIG_CURSIG is defined,
don't issue a PIOCSSIG if pr_cursig already contains the signal we
intend to set.
(info_proc_signals): If PROCFS_SIGPEND_OFFSET is defined, the
pending signals are numbered from 1 instead of 0.
(info_proc_mappings): Increase size of output format for addresses
if BFD_HOST_64_BIT is defined.
(procfs_stop): Renamed from child_stop.
(_initialize_procfs): Don't add procfs support if we have an
optional procfs and /proc is not accessible.
* 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.
