From 4dfc5dbc4e1b267d440dd515a42fe6fd96a8d860 Mon Sep 17 00:00:00 2001 From: John Baldwin Date: Mon, 18 Jan 2016 09:49:23 -0800 Subject: Add support for extracting thread names from cores. Add a new gdbarch method to extract a thread name from a core for a given thread. Use this new method in core_thread_name to implement the to_thread_name target op. gdb/ChangeLog: * corelow.c (core_thread_name): New function. (init_core_ops): Use "core_thread_name" for the "to_thread_name" target op. * gdbarch.sh (core_thread_name): New gdbarch callback. * gdbarch.h: Re-generate. * gdbarch.c: Re-generate. --- gdb/gdbarch.c | 32 ++++++++++++++++++++++++++++++++ 1 file changed, 32 insertions(+) (limited to 'gdb/gdbarch.c') diff --git a/gdb/gdbarch.c b/gdb/gdbarch.c index d45af1a..4143744 100644 --- a/gdb/gdbarch.c +++ b/gdb/gdbarch.c @@ -269,6 +269,7 @@ struct gdbarch gdbarch_core_xfer_shared_libraries_ftype *core_xfer_shared_libraries; gdbarch_core_xfer_shared_libraries_aix_ftype *core_xfer_shared_libraries_aix; gdbarch_core_pid_to_str_ftype *core_pid_to_str; + gdbarch_core_thread_name_ftype *core_thread_name; const char * gcore_bfd_target; int vtable_function_descriptors; int vbit_in_delta; @@ -612,6 +613,7 @@ verify_gdbarch (struct gdbarch *gdbarch) /* Skip verify of core_xfer_shared_libraries, has predicate. */ /* Skip verify of core_xfer_shared_libraries_aix, has predicate. */ /* Skip verify of core_pid_to_str, has predicate. */ + /* Skip verify of core_thread_name, has predicate. */ /* Skip verify of gcore_bfd_target, has predicate. */ /* Skip verify of vtable_function_descriptors, invalid_p == 0 */ /* Skip verify of vbit_in_delta, invalid_p == 0 */ @@ -824,6 +826,12 @@ gdbarch_dump (struct gdbarch *gdbarch, struct ui_file *file) "gdbarch_dump: core_read_description = <%s>\n", host_address_to_string (gdbarch->core_read_description)); fprintf_unfiltered (file, + "gdbarch_dump: gdbarch_core_thread_name_p() = %d\n", + gdbarch_core_thread_name_p (gdbarch)); + fprintf_unfiltered (file, + "gdbarch_dump: core_thread_name = <%s>\n", + host_address_to_string (gdbarch->core_thread_name)); + fprintf_unfiltered (file, "gdbarch_dump: gdbarch_core_xfer_shared_libraries_p() = %d\n", gdbarch_core_xfer_shared_libraries_p (gdbarch)); fprintf_unfiltered (file, @@ -3554,6 +3562,30 @@ set_gdbarch_core_pid_to_str (struct gdbarch *gdbarch, } int +gdbarch_core_thread_name_p (struct gdbarch *gdbarch) +{ + gdb_assert (gdbarch != NULL); + return gdbarch->core_thread_name != NULL; +} + +const char * +gdbarch_core_thread_name (struct gdbarch *gdbarch, struct thread_info *thr) +{ + gdb_assert (gdbarch != NULL); + gdb_assert (gdbarch->core_thread_name != NULL); + if (gdbarch_debug >= 2) + fprintf_unfiltered (gdb_stdlog, "gdbarch_core_thread_name called\n"); + return gdbarch->core_thread_name (gdbarch, thr); +} + +void +set_gdbarch_core_thread_name (struct gdbarch *gdbarch, + gdbarch_core_thread_name_ftype core_thread_name) +{ + gdbarch->core_thread_name = core_thread_name; +} + +int gdbarch_gcore_bfd_target_p (struct gdbarch *gdbarch) { gdb_assert (gdbarch != NULL); -- cgit v1.1
