* node.h: removed unused macrosnobu2018-09-131-101/+0
| | | | | | | * node.h (enum node_type): removed unused macros which redefine the same name enum values, and probably had ended the historical role. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64710 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* parse.y: remove coverage-related code fragmentsmame2018-08-221-0/+1
| | | | | | | | | | | | | The code fragments that initializes coverage data were scattered into both parse.y and compile.c. parse.y allocated a coverage data, and compile.c initialize the data. To remove this cross-cutting concern, this change moves the allocation from "coverage" function of parse.y to "rb_iseq_new_top" of iseq.c. For the sake, parse.y just counts the line number of the original source code, and the number is passed via rb_ast_body_t. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64508 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* node.c: Stop double meaning of NODE_FOR by introducing NODE_FOR_MASGNmame2018-01-161-1/+4
| | | | | | | | | NODE_FOR was used both for "for"-statement itself and for multi-assignment of for-statement (for x, y, in...end). This change separates the two purposes, NODE_FOR for the former, and newly introduced NODE_FOR_MASGN for the latter. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61871 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* parse.y: Remove almost all *_gen macros by passing parser_params explicitlymame2018-01-141-1/+1
| | | | | | | | | | | | | In parse.y many functions were suffixed "_gen" and had companion macros to pass struct parser_params implicitly, which made parse.c bigger and more obscure. This change expands and removes almost all "*_gen" macros. This requires explicit passing of struct parser_params, i.e., we need to write "foo(p, ..)" instead of "foo(..)". However, it is just extra three letters. I believe that this is easier to understand. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61818 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* Rename code_range to code_locationmame2018-01-091-116/+116
| | | | | | | | | | | Because the name "code_range" is ambiguous with encoding's. Abbreviations ("crange", and "cr") are also renamed to "loc". The traditional "code_location" (a pair of lineno and column) is renamed to "code_position". Abbreviations are also renamed (first_loc to beg_pos, and last_loc to end_pos). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61721 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* parse.y: Make consistent with the terms about code ranges and locationsmame2018-01-081-105/+105
| | | | | | | | | | | | | "loc" was ambiguous; it might refer both a location and a code range. This change uses "loc" for a location, and "crange" or "cr" for a code range. A location (abbr. loc) is a point in a program and consists of line number and column number. A code range (abbr. crange and cr) is a range within a program and consists of a pair of locations which is the first and the last. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61690 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* node.h: remove NODE_PRELUDEmame2018-01-051-4/+1
| | | | | | | | | | | NODE_PRELUDE contains a `BEGIN` node, a main node, and compile_option. This node is assumed that it must be located immediately under the root NODE_SCOPE, but this strange assumption is not so good, IMO. This change removes the assumtion; it integrates the former two nodes by block_append, and moves compile_option into rb_ast_body_t. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61610 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

| | | | | | | | | | r60655 changed the usage of bison by defining a customized YYLTYPE, which seemed to cause a random stall at rb_thread_terminate_all. Kazuki Tsujimoto investigated the issue and pointed out the commit that caused it. Thanks! git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@60660 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* Introduce rb_code_range_t and replace YYLTYPE with itmame2017-11-041-0/+5
| | | | | | | | | | | rb_code_range_t has two t_code_location_t, i.e., the first and last locations. This is used for YYLTYPE, tracked locations of bison, and will be also used for representing the "range", the first and the last locations of each NODE. Currently, each NODE keeps only the first location, though. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@60655 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When NODE_WHEN is compiled by iseq_compile_each0, the node passed to compile_when is NODE_WHEN (not NODE_CASE).

* Manage AST NODEs out of GCmame2017-10-271-8/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
