This changes the macro scope functions (sal_macro_scope, user_macro_scope, and default_macro_scope) to return a unique_xmalloc_ptr, then fixes up the users. This allowed for the removal of several cleanups. 2018-02-08 Tom Tromey <tom@tromey.com> * symtab.c (default_collect_symbol_completion_matches_break_on): Use unique_xmalloc_ptr. * macroscope.h: (sal_macro_scope, user_macro_scope) (default_macro_scope): Return unique_xmalloc_ptr. * macroscope.c (sal_macro_scope, user_macro_scope) (default_macro_scope): Return unique_xmalloc_ptr. * macroexp.h (macro_expand, macro_expand_once): Return unique_xmalloc_ptr. * macroexp.c (macro_expand, macro_expand_once): Return unique_xmalloc_ptr. * macrocmd.c (macro_expand_command, macro_expand_once_command) (info_macro_command, info_macros_command): Use unique_xmalloc_ptr. * compile/compile-c-support.c (write_macro_definitions): Use unique_xmalloc_ptr. * c-exp.y (c_parse): Use unique_xmalloc_ptr.
