Subject: Make search_all_symtabs() work in the same way as search_all_loctabs()
X-Git-Tag: svn/VALGRIND_3_0_0~324
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ba5255ccdceab074f9c74acc6ac5816cd1a088d6;p=thirdparty%2Fvalgrind.git

Make search_all_symtabs() work in the same way as search_all_loctabs()
and search_all_scopetabs(), ie. search through SegInfos instead of Segments.
This reduces m_debuginfo's dependency on m_aspacemgr.
