From eae7090bea9d7f129be7dddf89f8e177cdb2003d Mon Sep 17 00:00:00 2001 From: Gary Benson Date: Thu, 19 Jun 2014 09:12:26 +0100 Subject: Refactor and expose core-dumping functionality This commit exposes the functions that dump core outside utils.c. can_dump_core gains a new parameter, "limit_kind", to allow either the soft or hard limit to be checked, and its printing has separated into the new function warn_cant_dump_core. The new function can_dump_core_warn does what can_dump_core previously did (print and warn). gdb/ 2014-06-19 Gary Benson * utils.h (resource_limit_kind): New enum. (can_dump_core): New declaration. (warn_cant_dump_core): Likewise. (dump_core): Likewise. * utils.c (dump_core): Made nonstatic. Added new parameter "limit_kind". (can_dump_core): Made nonstatic. Moved printing code to... (warn_cant_dump_core): New function. (can_dump_core_warn): Likewise. (internal_vproblem): Replace calls to can_dump_core with calls to can_dump_core_warn. Supply new argument to each. --- gdb/utils.h | 24 ++++++++++++++++++++++++ 1 file changed, 24 insertions(+) (limited to 'gdb/utils.h') diff --git a/gdb/utils.h b/gdb/utils.h index 9a10281..a91f551 100644 --- a/gdb/utils.h +++ b/gdb/utils.h @@ -372,4 +372,28 @@ extern ULONGEST align_down (ULONGEST v, int n); extern LONGEST gdb_sign_extend (LONGEST value, int bit); +/* Resource limits used by getrlimit and setrlimit. */ + +enum resource_limit_kind + { + LIMIT_CUR, + LIMIT_MAX + }; + +/* Check whether GDB will be able to dump core using the dump_core + function.
