files).
* (SUBDIRS): Remove mswin.
* Change procedure for creating init.c. Speeds things up quite a
bit.
* config.in configure configure.in: Check for select, poll.
* Check for OSF header files before including hpux-thread.o.
* Don't configure doc or testsuite when building under MSVC.
* findvar.c value.h (read_register_pid write_register_pid): Make
global. Needed for hppa-tdep.c.
* (supply_register): Don't set pid to inferior_pid when supplying
registers.
* hppa-tdep.c (saved_pc_after_call): frame_saved_pc ->
FRAME_SAVED_PC.
* (frame_saved_pc): Change name to hppa_frame_saved_pc.
* (hppa_pop_frame): Don't use a pid of 0 with target_write_pc.
Use write_pc instead, which uses the correct pid.
* (target_read_pc target_write_pc): Use read/write_register_pid
instead of read/write_register to preserve the pid passed in.
* inftarg.c (child_can_run): Add flag child_suppress_run to allow
hpux-threads.c to override this as a runnable target.
* config/pa/nm-hppah.h: Define target_new_objfile and
target_pid_to_str.
* config/pa/tm-hppa.h (FRAME_SAVED_PC): Use hppa_frame_saved_pc
instead of frame_saved_pc.
* config/m68k/tm-m68k.h: Define TARGET_M68K for Wingdb.
* config/m68k/tm-monitor.h: Use FRAME_CHAIN_VALID_ALTERNATE, since
we can't easily determine the start file bounds with ELF.
* config/mips/tm-mips.h: Define TARGET_MIPS for Wingdb.
* hpux-thread.c: New file for HPUX/OSF thread support.
* osf-share/{README AT386/cma_thread_io.h HP800/cma_thread_io.h
RIOS/cma_thread_io.h cma_attr.h cma_deb_core.h cma_debug_client.h
cma_errors.h cma_handle.h cma_init.h cma_list.h cma_mutex.h
cma_sched.h cma_semaphore_defs.h cma_sequence.h cma_stack.h
cma_stack_int.h cma_tcb_defs.h cma_util.h}: New files for OSF
thread support.
