Subject: Class-ify lm_info_dsbt
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b091120773f8a740065b6449617cfbf1e0e789f4;p=binutils-gdb.git

Class-ify lm_info_dsbt

This patches makes lm_info_dsbt a "real" class.  It introduces a
destructor, initializes the field and replaces XCNEW/xfree with
new/delete.

gdb/ChangeLog:

	* solib-dsbt.c (struct lm_info_dsbt): Add destructor, initialize
	map field.
	(dsbt_current_sos): Allocate lm_info_dsbt with new.
	(dsbt_relocate_main_executable): Free lm_info_dsbt with delete
	and allocate with new.
	(dsbt_clear_solib, dsbt_free_so): Free lm_info_dsbt with delete.
