From: Yao Qi Date: Thu, 17 Oct 2013 13:15:21 +0000 (+0800) Subject: New field la_varobj_ops in struct language_defn X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a53b64eaa0816d9136f92b51f5e0d23e718b84f3;p=binutils-gdb.git New field la_varobj_ops in struct language_defn This is a follow-up series to move language stuff out of varobj.c. This patch adds a new field la_varobj_ops in struct language_defn so that each language has varobj-related options. Not every language supports varobj, and the operations are identical to operations of c languages. 'struct language_defn' is the ideal place to save all language-related operations. After this patch, some cleanups can be done in patch 2/2, which removes language-related stuff completely from varobj.c. Regression tested on x86_64-linux. gdb: 2013-10-25 Yao Qi * language.h (struct lang_varobj_ops): Declare.
