2015-07-27symbol.h: memoize hashval for RSymbolnormal
This speeds up the hash function for dynamic symbols. [ruby-core:70129] [Bug #11396], nearly up to Ruby 2.1 levels Power-of-two hash sizing [Feature #9425] speeds up cases where we have a good hash, but this means we can no longer hide behind weak hashes. Unfortunately, object IDs do not hash well, but we may use the extra space in the RSymbol struct to memoize the hash value. Further optimizations should be possible. For now, the st.c APIs force us to calculate rb_str_hash redundantly at dsym registration. * 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/trunk@51410 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2014-11-17symbol.c: symbol type predicate functionsnobu
* symbol.h (is_{local,global,instance,attrset,const,class,junk}_sym): fix ID type names. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@48470 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2014-10-14symbol.c: immortal IDsnobu
* symbol.c (global_symbols): make IDs immortal always, instead of treating dynamic symbols as IDs. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@47913 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2014-10-06symbol.h: move struct RSymbolnobu

2014-08-04symbol.c: move macrosnobu
* symbol.c (SYMBOL_PINNED, SYMBOL_PINNED_P, ID_DYNAMIC_SYM_P), (STATIC_SYM2ID, STATIC_ID2SYM): move from symbol.h as these macros are used only in symbol.c. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@47058 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2014-07-11symbol.c: remove dependency on parse.hnobu
* symbol.c (op_tbl): remove non-regular symbols. * symbol.c (global_symbols): start from the next of the preserved ID. * symbol.c: (rb_id2str): op_tbl does not exceed tLAST_OP_ID. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@46790 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2014-07-09symbol.c, symbol.h: split from parse.ynobu
* symbol.c, symbol.h: Symbol class implementation and internals, split from parse.y. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@46768 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
