Yukihiro "Matz" Matsumoto 425b5f32d6 Merge pull request #5049 from shuujii/use-type-tag-for-hash-code-in-ht_hash_func 
Use type tag for hash code in `ht_hash_func()`
 2020-07-25 19:40:05 +09:00
KOBAYASHI Shuji 0c88c71786 Use type tag for hash code in ht_hash_func() 
The function corresponding to `ht_hash_func()` was as follows in the days of
khash implementation (before d78acc7a).

  ```c
  mrb_hash_ht_hash_func(mrb_state *mrb, mrb_value key)
  {
    enum mrb_vtype t = mrb_type(key);
    ...
    switch (t) {
    ...
    default:
      hv = mrb_funcall(mrb, key, "hash", 0);
      h = (khint_t)t ^ (khint_t)mrb_fixnum(hv);
      break;
    }
    ...
  }
  ```

When switched to the segmented list implementation (d78acc7a), this function
was changed as follows.

  ```c
  sg_hash_func(mrb_state *mrb, seglist *t, mrb_value key)
  {
    enum mrb_vtype tt = mrb_type(key);
    ...
    switch (tt) {
    ...
    default:
      hv = mrb_funcall(mrb, key, "hash", 0);
      h = (size_t)t ^ (size_t)mrb_fixnum(hv);
      break;
    }
    ...
  }
  ```

Since the argument `t` was added, the variable for type tag was changed from
`t` to `tt`, but the variable used in the expression of `h` remained `t`.

Probably this is an omission of change, so fixed it.

Yukihiro "Matz" Matsumoto f868d7d357 Change the logic to calculate object (iv_tbl) size; #5045 2020-07-24 13:13:06 +09:00
Yukihiro "Matz" Matsumoto c69ca2c7f8 Merge pull request #5045 from dearblue/memsize_of

 2020-07-24 12:02:05 +09:00
dearblue ccd5f203bf Improve prototype for mrb_objspace_page_slot_size(); ref #5032 
If it qualify a return type that is not a pointer with `const`, the
compiler ignores it.
 2020-07-24 11:48:09 +09:00
dearblue 5c2b11d215 Avoid using FPU with mruby-os-memsize; ref #5032 
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.

Yukihiro "Matz" Matsumoto e7599050dc Fix a bug with ht_index called with size==0; fix #5046 
It happens when a hash made empty calls `rehash`.

Yukihiro "Matz" Matsumoto b920270508 Use more mrb_field_write_barrier for instance variables. 2020-07-22 15:01:55 +09:00
Yukihiro "Matz" Matsumoto 491aa1bfe5 Use more local variables. 
To make debugging easy, and to improve the performance little bit.

Yukihiro "Matz" Matsumoto c99bb756c4 Move gray_list update from gc_mark_children. 
The responsibility moved to caller to avoid confusion. Currently the
function is called from only 2 places, so it is relatively easy to
ensure not to update `gray_list` in the caller.  But the assumption
may change in the future.

Yukihiro "Matz" Matsumoto 097f525817 Avoid using mrb_ary_modify from the internal function. 
`mrb_ary_modify` calls `mrb_write_barrier`, so can cause the same
problem of the past `push`. It is provided for use-level API.
 2020-07-22 15:01:54 +09:00
Yukihiro "Matz" Matsumoto 5533c29833 Use mrb_field_write_barrier instead of mrb_write_barrier for push. 
When the array is very big, the simpler `mrb_write_barrier` causes
calling `gc_mark_children` for big arrays repeatedly. That would hinder
performance very badly.

Yukihiro "Matz" Matsumoto f76defd310 Use c specifier for mrb_get_args. 2020-07-19 07:47:07 +09:00
Yukihiro "Matz" Matsumoto d023adcb12 Add new specifier c to mrb_get_args. 
`C` retrieves a `mrb_value` that refers a class/module.
`c` retrieves a `struct RClass*` pointer to a class/module.

use-after-free problem.

Yukihiro "Matz" Matsumoto 233cb49903 Remove unnecessary stack adjustment in OP_CALL. 2020-06-25 06:57:43 +09:00
Yukihiro "Matz" Matsumoto 9cdf439db5 Free the original pointer if realloc failed. 
The POSIX `realloc` keep the original pointer untouched, so it can
easily leads to memory leakage. `mrb_realloc()` should handle those
bookkeeping, while `mrb_realloc_simple()` keeps the original `realloc`
behavior.
