* symbol.h (struct RSymbol): add hashval field * symbol.c (dsymbol_alloc): setup hashval field once * hash.c (rb_any_hash): return RSymbol->hashval directly * common.mk: hash.o depends on symbol.h Thanks to Bruno Escherl <bruno@escherl.net> for the bug report [ruby-core:70129] [Bug #11396] git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/branches/ruby_2_2@51589 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
