2017-10-27Manage AST NODEs out of GCmame
NODEs in AST are no longer objects managed by GC. This change will remove the restriction imposed by the GC. For example, a NODE can use more than five words (this is my primary purpose; we want to store the position data for each NODE, for coverage library), or even a NODE can have variable length (some kinds of NODEs have unused fields). To do this, however, we need more work, since Ripper still uses T_NODE objects managed by the GC. The life time of NODEs is more obvious than other kinds of objects; they are created at parsing, and they become disused immediately after compilation. This change releases all NODEs by a few `xfree`s after compilation, so performance will be improved a bit. In extreme example, `eval("x=1;" * 10000000)` runs much faster (40 sec. -> 7.8 sec. on my machine). The most important part of this change is `ast_t` struct, which has three contents: (1) NODE buffer (malloc'ed memory), (2) a reference to the root NODE, and (3) an array that contains objects that must be marked during parsing (such as literal objects). Some functions that had received `NODE*` arguments, must now receive `ast_t*`. * node.c, node.h: defines `ast_t` struct and related operations. * gc.c, internal.h: defines `imemo_ast`. * parse.y: makes `parser_params` struct have a reference to `ast_t`. Instead of `rb_node_newnode`, use `rb_ast_newnode` to create a NODE. * iseq.c, load.c, ruby.c, template/prelude.c.tmpl: modifies some functions to handle `ast_t*` instead of `NODE*`. * test/ruby/test_gc.rb: ad-hoc fix for a failed test. The test assumes GC eden is increased at startup by NODE object creation. However, this change now create no NODE object, so GC eden is not necessarily increased. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@60485 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2017-10-26Use rb_execution_context_t instead of rb_thread_tko1
to represent execution context [Feature #14038] * vm_core.h (rb_thread_t): rb_thread_t::ec is now a pointer. There are many code using `th` to represent execution context (such as cfp, VM stack and so on). To access `ec`, they need to use `th->ec->...` (adding one indirection) so that we need to replace them by passing `ec` instead of `th`. * vm_core.h (GET_EC()): introduced to access current ec. Also remove `ruby_current_thread` global variable. * cont.c (rb_context_t): introduce rb_context_t::thread_ptr instead of rb_context_t::thread_value. * cont.c (ec_set_vm_stack): added to update vm_stack explicitly. * cont.c (ec_switch): added to switch ec explicitly. * cont.c (rb_fiber_close): added to terminate fibers explicitly. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@60440 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2017-10-25Make imemo_alloc writebarrier-unprotectedmame
imemo_alloc provides a memory buffer whose contents are marked by GC. C code can access imemo_alloc buffer freely, so imemo_alloc must be considered writebarrier-unprotected. But T_IMEMO is writebarrier- protected by default, which caused a GC bug. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@60427 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2017-06-23use "enum ruby_tag_type" and TAG_NONE.ko1
Return value of EXEC_TAG() is saved by "int state". Instead of "int", use "enum ruby_tag_type". First EXEC_TAG() value should be 0, so that define TAG_NONE (= 0) and use it. Some code used "status" instead of "state". To make them clear, rename them to state. We can change variable name from "state" to "tag_state", but this ticket doesn't contain it. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@59155 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2017-06-01rename absolute_path to realpath internally and introduce pathobj.ko1
* vm_core.h: rename absolute_path to realpath because it is expected name. external APIs (#absolute_path methods) are remained. * vm_core.h: remove rb_iseq_location_struct::path and rb_iseq_location_struct::absolute_path and introduce pathobj. if given path equals to given absolute_path (and most of case it is true), pathobj is simply given path String. If it is not same, pathobj is Array and pathobj[0] is path and pathobj[1] is realpath. This size optimization reduce 8 bytes and sizeof(struct rb_iseq_constant_body) is 200 bytes -> 192 bytes on 64bit CPU. To support this change, the following functions are introduced: * pathobj_path() (defined in vm_core.h) * pathobj_realpath() (ditto) * rb_iseq_path() (decl. in vm_core.h) * rb_iseq_realpath() (ditto) * rb_iseq_pathobj_new() (ditto) * rb_iseq_pathobj_set() (ditto) * vm_core.h (rb_binding_t): use pathobj instead of path. If binding is given at eval methods, realpath (absolute_path) was caller's realpath. However, they should use binding's realpath. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@58979 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
