* avoid overflow in integer multiplication卜部昌平2019-10-091-3/+8
| | | | | | | This changeset basically replaces `ruby_xmalloc(x * y)` into `ruby_xmalloc2(x, y)`. Some convenient functions are also provided for instance `rb_xmalloc_mul_add(x, y, z)` which allocates x * y + z byes.

* Add compaction support to `rb_ast_t`Aaron Patterson2019-09-261-4/+53
| | | | This commit adds compaction support to `rb_ast_t`.
* `NODE_MATCH` needs to be marked / allocated from marking bucketAaron Patterson2019-09-101-1/+3
| | | | Fixes a test in RubySpec
* Revert "Reverting node marking until I can fix GC problem."Aaron Patterson2019-09-091-17/+140
| | | | This reverts commit 092f31e7e23c0ee04df987f0c0f979d036971804.
* Rename NODE_ARRAY to NODE_LIST to reflect its actual use casesYusuke Endoh2019-09-071-5/+5
| | | | | | | | | | 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.
* Reverting node marking until I can fix GC problem.Aaron Patterson2019-09-051-140/+17
| | | | | Looks like we're getting WB misses during stressful GC on startup. I am investigating.
* I forgot to add `break` in my case statementsAaron Patterson2019-09-051-0/+2
| | | | Give me a break.
* Stash tmpbuffer inside internal structsAaron Patterson2019-09-051-2/+10
| | | | | | 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.

* Create two buckets for allocating NODE structsAaron Patterson2019-09-051-16/+65
| | | | | | | | | 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.
* Stash the imemo buf at the end of the ID listAaron Patterson2019-09-051-1/+9
| | | | | | | Now we can reach the ID table buffer from the id table itself, so when SCOPE nodes are marked we can keep the buffers alive. This eliminates the need for the "mark array" during normal parse / compile (IOW *not* Ripper).
* Mark some tmpbufs via node objectsAaron Patterson2019-09-051-0/+3
| | | | This way we don't need to add the tmpbufs to a Ruby array for marking
* Directly mark node objects instead of using a mark arrayAaron Patterson2019-09-051-0/+50
| | | | | | | | This patch changes the AST mark function so that it will walk through nodes in the NODE buffer marking Ruby objects rather than using a mark array to guarantee liveness. The reason I want to do this is so that when compaction happens on major GCs, node objects will have their references pinned (or possibly we can update them correctly).
* Make pattern matching support **nil syntaxKazuki Tsujimoto2019-09-011-1/+6
|
* Directly mark compile options from the AST objectAaron Patterson2019-08-271-0/+1
| | | | | | | `rb_ast_t` holds a reference to this object, so it should mark the object. Currently it is relying on the `mark_ary` on `node_buffer` to ensure that the object stays alive. But since the array internals can move, this could cause a segv if compaction impacts the array.
* Let memory sizes of the various IMEMO object types be reflected correctlyLourens Naudé2019-07-231-2/+21

* node.h: Avoid a magic number to represent excessed commaYusuke Endoh2019-06-041-1/+8
| | | | | | `(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.

| | | | | | | | | NODE_FOR was used both for "for"-statement itself and for multi-assignment of for-statement (for x, y, in...end).

| | | | | | | | | | | 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

| | | | | | | | | | | | | "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
