2019-08-01introduce ar_hint_t.Koichi Sasada
Hash hint for ar_array is 1 byte (unsigned char). This patch introduce ar_hint_t which represents hint type.
2019-07-31move macro to internal.h for documentation.Koichi Sasada
13e84d5c0a changes enum to macro, but the flags usage information are lost in internal.h. It should be same place with other flags information.
2019-07-31Moved RHASH_LEV_MASK and turned into a macroNobuyoshi Nakada
Get rid of "ISO C restricts enumerator values to range of 'int'" error.
2019-07-31Use 1 byte hint for ar_table [Feature #15602]Koichi Sasada
On ar_table, Do not keep a full-length hash value (FLHV, 8 bytes) but keep a 1 byte hint from a FLHV (lowest byte of FLHV). An ar_table only contains at least 8 entries, so hints consumes 8 bytes at most. We can store hints in RHash::ar_hint. On 32bit CPU, we use 4 entries ar_table. The advantages: * We don't need to keep FLHV so ar_table only consumes 16 bytes (VALUEs of key and value) * 8 entries = 128 bytes. * We don't need to scan ar_table, but only need to check hints in many cases. Especially we don't need to access ar_table if there is no match entries (in many cases). It will increase memory cache locality. The disadvantages: * This technique can increase `#eql?` time because hints can conflicts (in theory, it conflicts once in 256 times). It can introduce incompatibility if there is a object x where x.eql? returns true even if hash values are different. I believe we don't need to care such irregular case. * We need to re-calculate FLHV if we need to switch from ar_table to st_table (e.g. exceeds 8 entries). It also can introduce incompatibility, on mutating key objects. I believe we don't need to care such irregular case too. Add new debug counters to measure the performance: * artable_hint_hit - hint is matched and eql?#=>true * artable_hint_miss - hint is not matched but eql?#=>false * artable_hint_notfound - lookup counts
2019-07-31remove RHash::iter_lev.Koichi Sasada
iter_lev is used to detect the hash is iterating or not. Usually, iter_lev should be very small number (1 or 2) so `int` is overkill. This patch introduce iter_lev in flags (7 bits, FL13 to FL19) and if iter_lev exceeds this range, save it in hidden attribute. We can get 1 word in RHash. We can't modify frozen objects. Therefore I added new internal API `rb_ivar_set_internal()` which allows us to set an attribute even if the target object is frozen if the name is hidden ivar (the name without `@` prefix).
2019-07-28Reuse match dataNobuyoshi Nakada
* string.c (rb_str_split_m): reuse occupied match data. [Bug #16024]
2019-07-22constify again.Koichi Sasada
Same as last commit, make some fields `const`. include/ruby/ruby.h: * Rasic::klass * RArray::heap::aux::shared_root * RRegexp::src internal.h: * rb_classext_struct::origin_, redefined_class * vm_svar::cref_or_me, lastline, backref, others * vm_throw_data::throw_obj * vm_ifunc::data * MEMO::v1, v2, u3::value While modifying this patch, I found write-barrier miss on rb_classext_struct::redefined_class. Also vm_throw_data::throw_state is only `int` so change the type.
2019-07-22constify RHash::ifnone.Koichi Sasada
RHash::ifnone should be protected by write-barriers so this field should be const. However, to introduce GC.compact, the const was removed. This commit revert this removing `const` and modify gc.c `TYPED_UPDATE_IF_MOVED` to remove `const` forcely by a type cast.
2019-07-16Moved the check for `exception` to rb_execarg_addoptNobuyoshi Nakada
Check for `exception` option in rb_execarg_addopt, as well as other options. And then raise a particular ArgumentError if it is not allowed.

2019-06-01Make opt_aref instruction support Integer#[]Yusuke Endoh
only when its receiver and the argument are both Integers. Since 6bedbf4625, Integer#[] has supported a range extraction. This means that Integer#[] now accepts multiple arguments, which made the method very slow unfortunately. This change fixes the performance issue by adding a special handling for its traditional use case: `num[idx]` where both `num` and `idx` are Integers.
2019-05-31Use UNALIGNED_MEMBER_PTRNobuyoshi Nakada
* internal.h (UNALIGNED_MEMBER_ACCESS, UNALIGNED_MEMBER_PTR): moved from eval_intern.h. * compile.c iseq.c, vm.c: use UNALIGNED_MEMBER_PTR for `entries` in `struct iseq_catch_table`. * vm_eval.c, vm_insnhelper.c: use UNALIGNED_MEMBER_PTR for `body` in `rb_method_definition_t`.

2019-01-06internal.h: unify our own stdtbool.h implementationk0kubun
because we had another one in missing/stdbool.h as well. Assuming that _Bool does not exist when stdbool.h is absent, I'm in favor of r57462 implementation rather than r61326. Note that Visual Studio 2013 has stdbool.h and thus r57462's commit message is somewhat misleading. This missing/stdbool.h is for Visual Studio 2012 or older, and for Oracle Solaris Studio 12.2 or older because it's added in 12.3 https://docs.oracle.com/cd/E24457_01/html/E21987/gkeza.html. missing/stdbool.h: ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@66739 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
