2019-09-09Revert "Reverting node marking until I can fix GC problem."Aaron Patterson
This reverts commit 092f31e7e23c0ee04df987f0c0f979d036971804.
2019-09-07Rename NODE_ARRAY to NODE_LIST to reflect its actual use casesYusuke Endoh
and NODE_ZARRAY to NODE_ZLIST. NODE_ARRAY is used not only by an Array literal, but also the contents of Hash literals, method call arguments, dynamic string literals, etc. In addition, the structure of NODE_ARRAY is a linked list, not an array. This is very confusing, so I believe `NODE_LIST` is a better name.
2019-09-05Reverting node marking until I can fix GC problem.Aaron Patterson
Looks like we're getting WB misses during stressful GC on startup. I am investigating.
2019-09-05Stash tmpbuffer inside internal structsAaron Patterson
I guess those AST node were actually used for something, so we'd better not touch them. Instead this commit just puts the tmpbuffer inside a different internal struct so that we can mark them.
2019-09-05Create two buckets for allocating NODE structsAaron Patterson
This commit adds two buckets for allocating NODE structs, then allocates "markable" NODE objects from one bucket. The reason to do this is so when the AST mark function scans nodes for VALUE objects to mark, we only scan NODE objects that we know to reference VALUE objects. If we *did not* divide the objects, then the mark function spends too much time scanning objects that don't contain any references.
2019-09-01Make pattern matching support **nil syntaxKazuki Tsujimoto
2019-08-30Support **nil syntax for specifying a method does not accept keyword argumentsJeremy Evans
This syntax means the method should be treated as a method that uses keyword arguments, but no specific keyword arguments are supported, and therefore calling the method with keyword arguments will raise an ArgumentError. It is still allowed to double splat an empty hash when calling the method, as that does not pass any keyword arguments. Notes: Merged: https://github.com/ruby/ruby/pull/2395

2019-06-05Fix grammar of macro name: ECCESSED -> ECCESSIVEMartin Dürst
Fix the name of the macro variable introduced in 0872ea5330 from NODE_SPECIAL_EXCESSED_COMMA to NODE_SPECIAL_EXCESSIVE_COMMA.
2019-06-04node.h: Avoid a magic number to represent excessed commaYusuke Endoh
`(ID)1` was assigned to NODE_ARGS#rest_arg for `{|x,| }`. This change removes the magic number by introducing an explicit macro variable for it: NODE_SPECIAL_EXCESSED_COMMA.
2019-05-05parse.y: duplicated when clause warningNobuyoshi Nakada
* parse.y (case_args): moved "duplicated when clause" warning from compile phase, so that `ruby -wc` shows them.

[ruby-core:87945] [Feature #14912] git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@67586 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2019-03-15node.h: introduce nd_brace to determine if a hash literal is a keywordmame
NODE_HASH#nd_brace is a flag that is 1 for `foo({ k: 1 })` and 0 for `foo(k: 1)`. nd_alen had been abused for the flag (and the implementation is completely the same), but an explicit name is better to read. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@67266 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* node.h: Add `nd_first_loc` and `nd_set_first_loc` * parse.y: Fix to start with the beginning of `->` . e.g. The locations of the NODE_LAMBDA is fixed: ``` -> x { 1 + 2 } ``` * Before ``` NODE_LAMBDA (line: 1, location: (1,2)-(1,14)) ``` * After ``` NODE_LAMBDA (line: 1, location: (1,0)-(1,14)) ``` git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@65221 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2018-09-13node.h: removed unused macrosnobu
* 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
2018-08-22parse.y: remove coverage-related code fragmentsmame
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
2018-08-22node.h (rb_ast_t): move its field mark_ary to node_buffer_tmame
I want to add a new field to rb_ast_t whose size is restricted because it is an imemo. This change makes one room in rb_ast_t. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64507 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2018-05-09type func(); is different from type func(void);shyouhei
If a function declarator includes no parameter list, that doesn't mean the function takes zero parameter. rb_ast_new here does take zero parameter, so it should be explicitly prototypes as (void). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@63370 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2018-01-16node.c: Stop double meaning of NODE_FOR by introducing NODE_FOR_MASGNmame
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
2018-01-14parse.y: Remove almost all *_gen macros by passing parser_params explicitlymame
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
2018-01-09Rename code_range to code_locationmame
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
2018-01-08parse.y: Make consistent with the terms about code ranges and locationsmame
"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

2018-01-05node.h: remove NODE_PRELUDEmame
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

2017-11-05Revert "Introduce rb_code_range_t and replace YYLTYPE with it"mame
