2019-08-27rb_ensure now free from ANYARGS卜部昌平
After 5e86b005c0f2ef30df2f9906c7e2f3abefe286a2, I now think ANYARGS is dangerous and should be extinct. This commit deletes ANYARGS from rb_ensure, which also revealed many arity / type mismatches.
2019-08-27decouple compile.c usage of imemo_ifunc卜部昌平
After 5e86b005c0f2ef30df2f9906c7e2f3abefe286a2, I now think ANYARGS is dangerous and should be extinct. This commit deletes ANYARGS from struct vm_ifunc, but in doing so we also have to decouple the usage of this struct in compile.c, which (I think) is an abuse of ANYARGS.

2019-08-09add rp() and bp() in internal.h.Koichi Sasada
debug utility macro rp() (rp_m()) and bp() are introduced. * rp(obj) shows obj information w/o any side-effect to STDERR. * rp_m(m, obj) is similar to rp(obj), but show m before. * bp() is alias of ruby_debug_breakpoint(), which is registered as a breakpoint in run.gdb (used by `make gdb` or make gdb-ruby`).
2019-08-09introduce RCLASS_CLONED flag for inline cache.Koichi Sasada
Methods on duplicated class/module refer same constant inline cache (IC). Constant access lookup should be done for cloned class/modules but inline cache doesn't check it. To check it, this patch introduce new RCLASS_CLONED flag which are set when if class/module is cloned (both orig and dst). [Bug #15877]

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

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.
