From mboxrd@z Thu Jan 1 00:00:00 1970 From: Stafford Horne Date: Tue, 19 Dec 2017 23:22:56 +0900 Subject: [OpenRISC] [PATCH v3 3/4] reggroups: Create reggroup_gdbarch_new for dynamic reggroups In-Reply-To: <20171219142257.13402-1-shorne@gmail.com> References: <20171219142257.13402-1-shorne@gmail.com> Message-ID: <20171219142257.13402-4-shorne@gmail.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: openrisc@lists.librecores.org Traditionally reggroups have been created via reggroup_new() during initialization code and never freed. Now, if we want to initialize reggroups dynamically (i.e. in target description) we should be able to free them. Create this function reggroup_gdbarch_new() which will allocate the reggroup memory onto the passed gdbarch obstack. gdb/ChangeLog: 2017-06-10 Stafford Horne * reggroups.c (reggroup_gdbarch_new): New function. * reggroups.h (reggroup_gdbarch_new): New function. --- gdb/reggroups.c | 12 ++++++++++++ gdb/reggroups.h | 4 ++++ 2 files changed, 16 insertions(+) diff --git a/gdb/reggroups.c b/gdb/reggroups.c index 5d5e33f2a3..acad91a0ab 100644 --- a/gdb/reggroups.c +++ b/gdb/reggroups.c @@ -46,6 +46,18 @@ reggroup_new (const char *name, enum reggroup_type type) return group; } +struct reggroup * +reggroup_gdbarch_new (struct gdbarch *gdbarch, const char *name, + enum reggroup_type type) +{ + struct reggroup *group = GDBARCH_OBSTACK_ZALLOC (gdbarch, + struct reggroup); + + group->name = gdbarch_obstack_strdup (gdbarch, name); + group->type = type; + return group; +} + /* Register group attributes. */ const char * diff --git a/gdb/reggroups.h b/gdb/reggroups.h index 18fc1bf294..c1653cd39d 100644 --- a/gdb/reggroups.h +++ b/gdb/reggroups.h @@ -41,6 +41,10 @@ extern struct reggroup *const restore_reggroup; /* Create a new local register group. */ extern struct reggroup *reggroup_new (const char *name, enum reggroup_type type); +/* Create a new register group allocated onto the gdbarch obstack. */ +extern struct reggroup *reggroup_gdbarch_new (struct gdbarch *gdbarch, + const char *name, + enum reggroup_type type); /* Add a register group (with attribute values) to the pre-defined list. */ extern void reggroup_add (struct gdbarch *gdbarch, struct reggroup *group); -- 2.13.6
