From 5d394f707245c12a8839461df83a06a0997c1698 Mon Sep 17 00:00:00 2001 From: Stu Grossman Date: Tue, 8 Oct 1996 17:06:17 +0000 Subject: * Makefile.in: Add rule for hpux-thread.o (needs special header 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. --- gdb/hppa-tdep.c | 30 ++++++++++++++++++------------ 1 file changed, 18 insertions(+), 12 deletions(-) (limited to 'gdb/hppa-tdep.c') diff --git a/gdb/hppa-tdep.c b/gdb/hppa-tdep.c index 3c3f058..05463b4 100644 --- a/gdb/hppa-tdep.c +++ b/gdb/hppa-tdep.c @@ -812,13 +812,13 @@ saved_pc_after_call (frame) the stub will return to out of the stack. */ u = find_unwind_entry (pc); if (u && u->stub_type != 0) - return frame_saved_pc (frame); + return FRAME_SAVED_PC (frame); else return pc; } CORE_ADDR -frame_saved_pc (frame) +hppa_frame_saved_pc (frame) struct frame_info *frame; { CORE_ADDR pc = get_frame_pc (frame); @@ -1394,7 +1394,7 @@ hppa_pop_frame () else { npc = read_register (RP_REGNUM); - target_write_pc (npc, 0); + write_pc (npc); } write_register (FP_REGNUM, read_memory_integer (fp, 4)); @@ -1749,12 +1749,15 @@ CORE_ADDR target_read_pc (pid) int pid; { - int flags = read_register (FLAGS_REGNUM); + int flags = read_register_pid (FLAGS_REGNUM, pid); - if (flags & 2) { - return read_register (31) & ~0x3; - } - return read_register (PC_REGNUM) & ~0x3; + /* The following test does not belong here.
