shuujii/simplify-MSVC-detection-to-mrb_static_assert
Simplify MSVC detection to `mrb_static_assert`
|
|
|
|
shuujii/use-normal-static_assert-in-mrb_static_assert-as-much-as-possible
Use normal `static_assert` in `mrb_static_assert` as much as possible
|
|
Use `struct _stat32` instead of `struct __stat32`
|
|
It is described as `struct __stat32` in the MSVC reference manual.
https://docs.microsoft.com/en-us/cpp/c-runtime-library/reference/stat-functions?view=vs-2019
But it doesn't really exist, so it must use `struct _stat32`.
It also replaces `struct __stat64` with `struct _stat64` to make it look
nicer.

* `_Static_assert` can also be used with `-std=gnu99` on GCC >= 4.6.
* `static_assert` can be used on MSVC.
* `static_assert` can be used even on old G++/Clang++ if
`__GXX_EXPERIMENTAL_CXX0X__` is defined.

shuujii/allow-mrb_static_assert-to-be-used-outside-of-functions
Allow `mrb_static_assert()` to be used outside of functions
|
|
The use of `struct` is an idea by @dearblue.
|
|
|
|
|
|
Note that the home brew version of `mrb_static_assert` only works within
the function body. This reverts commit 8f99689.

Extend the `cipush()` and `cipop()` functions
|
|
Improve `rake benchmark`
|
|
- Use POSIX format instead of GNU extension for `time` command.
For example FreeBSD's `time(1)` does not have GNU extensions available.
- Sort `benchmark/bm_*.rb`.
This is because the order of the bar graph cannot be uniquely
determined depending on the result of `Dir.glob`.

- Remove ` kh_put_prepare` function used only internally
- Remove `n_occupied` member from `kh_` struct
|
|
`puts` should print newline when called without arguments.

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.

Update document for `ObjectSpace.memsize_of` [ci skip]
|
|
- Returns the updated call info.
- Unify the processing around `cipush()`.
- `cipop()` restores the stack.
|
|
The `recurse` keyword is removed by f00657ead7c3e5f6f9a346d7797a280b5c9f02fa.

Improve `mruby-os-memsize`
|
|
If it qualify a return type that is not a pointer with `const`, the
compiler ignores it.
|
|
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.

It happens when a hash made empty calls `rehash`.
