From f7efd549485db1fd84dbd2f2ee36d80c2739f224 Mon Sep 17 00:00:00 2001 From: Stafford Horne Date: Wed, 27 Dec 2017 23:36:31 +0900 Subject: reggroups: Add reggroup_gdbarch_new, reggroup_find for dynamic reggroups 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. Also creating reggroup_find() as a utility to find a gdbarch registered reggroup object by name. gdb/ChangeLog: yyyy-mm-dd Stafford Horne * reggroups.c (reggroup_gdbarch_new): New function. (reggroup_find): New function. * reggroups.h (reggroup_gdbarch_new): New function.
