From 43dce4394513d15ba8122c3bf442ec1028d93feb Mon Sep 17 00:00:00 2001 From: Simon Marchi Date: Fri, 27 Oct 2017 22:01:21 -0400 Subject: Allocate breakpoint_objfile_data with new Allocate with new and free with delete. This allows using an std::vector in the following patch. I renamed free_breakpoint_probes to free_breakpoint_objfile_data, because it now doesn't only free the probes vector, but also the breakpoint_objfile_data structure itself. gdb/ChangeLog: * breakpoint.c (breakpoint_objfile_data): Initialize fields. (get_breakpoint_objfile_data): Allocate breakpoint_objfile_data with new. (free_breakpoint_probes): Rename to ... (free_breakpoint_objfile_data): ... this, and call delete on bp_objfile_data.. --- gdb/ChangeLog | 9 +++++++++ gdb/breakpoint.c | 27 +++++++++++++-------------- 2 files changed, 22 insertions(+), 14 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index c1a3dee..9b91214 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,12 @@ +2017-10-27 Simon Marchi + + * breakpoint.c (breakpoint_objfile_data): Initialize fields. + (get_breakpoint_objfile_data): Allocate breakpoint_objfile_data + with new. + (free_breakpoint_probes): Rename to ... + (free_breakpoint_objfile_data): ... this, and call delete on + bp_objfile_data.. + 2017-10-27 Simon Marchi * auto-load.c: Don't include gdb_vecs.h, include algorithm. diff --git a/gdb/breakpoint.c b/gdb/breakpoint.c index 10fccb8..3601e7d 100644 --- a/gdb/breakpoint.c +++ b/gdb/breakpoint.c @@ -3183,28 +3183,28 @@ static const char *const longjmp_names[] = struct breakpoint_objfile_data { /* Minimal symbol for "_ovly_debug_event" (if any). */ - struct bound_minimal_symbol overlay_msym; + struct bound_minimal_symbol overlay_msym {}; /* Minimal symbol(s) for "longjmp", "siglongjmp", etc. (if any). */ - struct bound_minimal_symbol longjmp_msym[NUM_LONGJMP_NAMES]; + struct bound_minimal_symbol longjmp_msym[NUM_LONGJMP_NAMES] {}; /* True if we have looked for longjmp probes. */ - int longjmp_searched; + int longjmp_searched = 0; /* SystemTap probe points for longjmp (if any). */ - VEC (probe_p) *longjmp_probes; + VEC (probe_p) *longjmp_probes = NULL; /* Minimal symbol for "std::terminate()" (if any). */ - struct bound_minimal_symbol terminate_msym; + struct bound_minimal_symbol terminate_msym {}; /* Minimal symbol for "_Unwind_DebugHook" (if any). */ - struct bound_minimal_symbol exception_msym; + struct bound_minimal_symbol exception_msym {}; /* True if we have looked for exception probes. */ - int exception_searched; + int exception_searched = 0; /* SystemTap probe points for unwinding (if any). */ - VEC (probe_p) *exception_probes; + VEC (probe_p) *exception_probes = NULL; }; static const struct objfile_data *breakpoint_objfile_key; @@ -3232,23 +3232,22 @@ get_breakpoint_objfile_data (struct objfile *objfile) objfile_data (objfile, breakpoint_objfile_key)); if (bp_objfile_data == NULL) { - bp_objfile_data = - XOBNEW (&objfile->objfile_obstack, struct breakpoint_objfile_data); - - memset (bp_objfile_data, 0, sizeof (*bp_objfile_data)); + bp_objfile_data = new breakpoint_objfile_data (); set_objfile_data (objfile, breakpoint_objfile_key, bp_objfile_data); } return bp_objfile_data; } static void -free_breakpoint_probes (struct objfile *obj, void *data) +free_breakpoint_objfile_data (struct objfile *obj, void *data) { struct breakpoint_objfile_data *bp_objfile_data = (struct breakpoint_objfile_data *) data; VEC_free (probe_p, bp_objfile_data->longjmp_probes); VEC_free (probe_p, bp_objfile_data->exception_probes); + + delete bp_objfile_data; } static void @@ -15544,7 +15543,7 @@ _initialize_breakpoint (void) observer_attach_memory_changed (invalidate_bp_value_on_memory_change); breakpoint_objfile_key - = register_objfile_data_with_cleanup (NULL, free_breakpoint_probes); + = register_objfile_data_with_cleanup (NULL, free_breakpoint_objfile_data); breakpoint_chain = 0; /* Don't bother to call set_breakpoint_count. $bpnum isn't useful -- cgit v1.1
