2021-12-31class.c, variable,c: replace `size_t` by `int`.Yukihiro "Matz" Matsumoto
That reduce memory consumption by iv/mt tables.
2021-12-27variable.c: need to initialize `size` of iv table.Yukihiro "Matz" Matsumoto
2021-12-13variable.c: resurrect `size` member in `iv_tbl`.Yukihiro "Matz" Matsumoto
The existence of this member reduces memory and execution time.
2021-12-08variable.c: fix clang integer warning.Yukihiro "Matz" Matsumoto
2021-12-07variable.c: avoid redundant iv scan in `mrb_mod_cv_set()`.Yukihiro "Matz" Matsumoto
Now `iv_get()` returns `pos+1` if it finds the entry, so you don't need to call `iv_put()`. You can replace the entry value by assigning to `t->ptr[pos-1]`.
2021-12-04variable.c: reduce array access in iv hash table.Yukihiro "Matz" Matsumoto
2021-12-03variable.c: avoid `mrb_undef_value()` for delete entries.Yukihiro "Matz" Matsumoto
Instead embed deleted flag in the key (`mrb_sym` only occupies 30bits).
2021-12-03variable.c: remove `size` member from `iv_tbl` to reduce memory.Yukihiro "Matz" Matsumoto
`iv_size()` is approximated by the allocated table size.
2021-12-03variable.c: first iv allocation size should be 4 instead of 1.Yukihiro "Matz" Matsumoto
2021-12-03variable.c: should not access `NULL[0]` to avoid asan warnings.Yukihiro "Matz" Matsumoto
2021-12-01variable.c: reduce memory usage of instance variable tableYukihiro "Matz" Matsumoto
This is a fundamentally simplified reimplementation of #5317 by @shuujii Instead of having array of `struct iv_elem`, we have sequences of keys and values packed in single chunk of malloc'ed memory. We don't have to worry about gaps from alignment, especially on 64 bit architecture, where `sizeof(struct iv_elem)` probably consumes 16 bytes, but `sizeof(mrb_sym)+sizeof(mrb_value)` is 12 bytes. In addition, this change could improve memory access locality. close #5317
2021-06-17variable.c: add `skip` argument to skip `base` class in lookup.Yukihiro "Matz" Matsumoto
`mrb_vm_const_get` function looks up the constant first in the base class, so that fallback `const_get` need not to search from the base.
2021-06-17variable.c: refactor `mrb_vm_const_get` function.Yukihiro "Matz" Matsumoto
2021-06-17variable.c: skip prepended module for constant lookup.Yukihiro "Matz" Matsumoto
```ruby module M FOO = 'm' end class A FOO = 'a' prepend M end class B < A def foo p FOO end end B.new.foo # should print `m` not `a` ```

2021-01-26Revert "Minimize the changes in #5277"Yukihiro "Matz" Matsumoto
This reverts commit dc51d89ac22acc60b9bfeed87115863565b74085.
2021-01-22Minimize the changes in #5277Yukihiro "Matz" Matsumoto
Instead of including `mruby/presym.h` everywhere, we provided the fallback `mruby/presym.inc` under `include/mruby` directory, and specify `-I<build-dir>/include` before `-I<top-dir>/include` in `presym.rake`. So even when someone drops `-I<build-dir>/include` in compiler options, it just compiles without failure.
2021-01-11Avoid including `presym.inc` in existing header filesKOBAYASHI Shuji
Addressed an issue where existing programs linking `libmruby.a` could only be built by adding `<build-dir>/include` to compiler's include path.
2020-11-12Remove unused argument of `mrb_obj_iv_tbl_memsize`KOBAYASHI Shuji
2020-10-12Use hash table instead of segment list for instance variables.Yukihiro "Matz" Matsumoto
2020-10-12Generate C struct from `irep` instead of binary dump.Yukihiro "Matz" Matsumoto
2020-10-12Add functions that take symbols as arguments.Yukihiro "Matz" Matsumoto
- :
2020-10-12Add `MRB_SYM()` for inline symbols.Yukihiro "Matz" Matsumoto
2020-08-11Fix `mrb_int` and `size_t` combination warnings.Yukihiro "Matz" Matsumoto
2020-07-24Change the logic to calculate object (`iv_tbl`) size; #5045Yukihiro "Matz" Matsumoto
2020-07-24Merge pull request #5045 from dearblue/memsize_ofYukihiro "Matz" Matsumoto
Improve `mruby-os-memsize`
2020-07-24Avoid using FPU with `mruby-os-memsize`; ref #5032dearblue
And, in the calculation of the instance variable size, the fraction was always rounded down because of division of integers, so fix it. At the same time, test items that are no longer passed due to this change are deleted.
2020-07-22Use more `mrb_field_write_barrier` for instance variables.Yukihiro "Matz" Matsumoto

2019-11-16Revert "Implement Ruby2.7's frozen strings from `Symbol#to_s`"KOBAYASHI Shuji
This feature was reverted from Ruby 2.7.
2019-10-20Use `mrb_str_cat_str` instead of `mrb_str_concat` if possibleKOBAYASHI Shuji

2019-09-26Use type predicate macros instead of `mrb_type` if possibleKOBAYASHI Shuji
For efficiency with `MRB_WORD_BOXING` (implement type predicate macros for all `enum mrb_vtype`).
2019-09-25Rename symbol-to-string functions; close #4684Yukihiro "Matz" Matsumoto

2019-09-20Fix compatibility issue of class variables.Yukihiro "Matz" Matsumoto
Singleton class definition do not introduce its own class variable scope in CRuby/JRuby. So should mruby. ``` module Mod1 class << Object.new C = 1 @@cv = 1 p Module.nesting, # => [#<Class:#<Object:0x55cb16e60a50>>, Mod1] constants, # => [:C] class_variables, # => [] Mod1.class_variables # => [:@@cv] end end ```

2019-08-11Revert "Should have cleared `mrb->globals` in `mrb_gc_free_gv`; fix #4618"Yukihiro "Matz" Matsumoto

2019-08-05Use new specifiers/modifiers of `mrb_vfromat()`KOBAYASHI Shuji
The binary sizes (gems are only `mruby-bin-mruby`) are reduced slightly in my environment than before the introduction of new specifiers/modifiers (5116789a) with this change. ------------+-------------------+-------------------+-------- BINARY | BEFORE (5116789a) | AFTER (This PR) | RATIO ------------+-------------------+-------------------+-------- mruby | 593416 bytes | 593208 bytes | -0.04% libmruby.a | 769048 bytes | 767264 bytes | -0.23% ------------+-------------------+-------------------+-------- BTW, I accidentally changed `tasks/toolchains/visualcpp.rake` at #4613, so I put it back.
2019-06-25Fixed `mrb_iv_remove` with immediate objects; fix #4519Yukihiro "Matz" Matsumoto
The #4520 tried to address the issue, but it changes the type of `mrb_check_frozen` argument; close #4520

2019-06-10`Kernel#global_variables` should not include undefined `$1`-`$9`KOBAYASHI Shuji
- They are not include in Ruby. - Appear in duplicate when `$1`-`$9` are defined.
