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.

* README: Add note about SPARCworks cc release 3.0 and higher. 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.
