Yukihiro "Matz" Matsumoto 2256bb07b0 Remove MRB_METHOD_TABLE_INLINE. 
`MRB_METHOD_TABLE_INLINE` was fragile. It requires `-falign-functions=n`.
On platform that uses higher bits of function pointers, you can use new
`MRB_METHOD_T_STRUCT` configuration macro.

Yukihiro "Matz" Matsumoto 30f3787248 Raise ArgumentError by aspec check; ref #4688 
This is partial `aspec` check that only checks `MRB_ARGS_NONE()`.

Yukihiro "Matz" Matsumoto 2764fdf9f0 Share common definition of MRB_METHOD_FUNC_FL. 2019-09-16 10:10:09 +09:00
Yukihiro "Matz" Matsumoto 0eb9355acd Use bit shifting to pack function pointers to mrb_method_t. 
So you don't need `-falign-functions=2` anymore. Instead your platform
must not use higher bits of the pointer (true for most platforms).
If not, you have to use `struct mrb_method_t` version.

KOBAYASHI Shuji d47bd0a2cd Optimize mrb_bool() with MRB_WORD_BOXING 2019-09-08 12:17:25 +09:00
KOBAYASHI Shuji 17c53040ab Increase symbol bit size on 32-bit mode with MRB_WORD_BOXING 
This change increases the max length of lower inline symbols to 5 bytes.

KOBAYASHI Shuji 19e2cc187b Avoid bit fields in mrb_value; ref b2c3d88f 
The changes at b2c3d88f were inappropriate because the memory layout of bit
fields are implementation defined. Therefor, I fixed it not to use bit
fields.

Yukihiro "Matz" Matsumoto 5cd52d2d69 Fix an error in refactoring; fix #4682 2019-09-02 08:41:44 +09:00
Yukihiro "Matz" Matsumoto 1a4ea94bc7 Fix mrb_immediate_p(MRB_TT_FREE) to return false; ref #4679 2019-08-31 23:19:08 +09:00
Yukihiro "Matz" Matsumoto d48a2190bf Refactor #4662 with different names. 2019-08-31 22:14:25 +09:00
KOBAYASHI Shuji b2c3d88fbf Implement mrb_immediate_p macro for MRB_WORD_BOXING 
The default implementation of `mrb_immediate_p` uses `mrb_type`. However,
in `MRB_WORD_BOXING`, `mrb_type` has many branches and is inefficient, so
provide an implementation that does not use `mrb_type`.

KOBAYASHI Shuji be78b5d8f7 Fix RBreak exceeding 6 words on 32-bit mode w/o boxing and MRB_USE_FLOAT 
ref: https://github.com/mruby/mruby/pull/4483#issuecomment-498001736

In this configuration, `tt` of `RBreak::val` is set into `RBreak::flags`.

Yukihiro "Matz" Matsumoto 4c001673b6 Avoid C++ strict aliasing warning. 
Based on code proposed by @dearblue to avoid the warning:
`dereferencing type-punned pointer will break strict-aliasing rules`.
 2019-08-20 22:50:21 +09:00
KOBAYASHI Shuji 8157672a29 Use RBasic padding for embedded string on 64-bit CPU 
On 64-bit CPU, there is padding in `RBasic`, so reorder the fields and use
it as buffer of embedded string. This change allows 4 more bytes to be
embedded on 64-bit CPU.

However, an incompatibility will occur if `RString::as::ary` is accessed
directly because `RString` structure has changed.

Ryan Lopopolo b5662c87c8 Allow external definition of MRB_API macro 
When building WebAssembly targets with clang (e.g. wasm32-unknown-unknown), all
symbols are hidden by default. To export a symbol, it must be marked with

    __attribute__((visibility(default)))

Rather than detecting this exotic target in mruby, allow MRB_API to be defined
externally.

KOBAYASHI Shuji caba5fef27 Refactor set/unset string type flags 
Introduce `RSTR_SET_TYPE_FLAG` macro to set the specified string type flag and
clear the others.

Yukihiro "Matz" Matsumoto 9f6328d499 Remove MRB_API from functions only called from vm.c. 
* `mrb_vm_define_class`
* `mrb_vm_define_module`

Only functions called from user code requires `MRB_API`.

KOBAYASHI Shuji 450684ab33 mrb_str_modify_keep_ascii can embed one more byte 
The condition to make an embedded string was incorrect. Because there were
several similar codes, extracted into `RSTR_EMBEDDABLE_P` macro.

Yukihiro "Matz" Matsumoto b377b7d580 Update mrb_to_str and related functions. 
Contrary to the name, `mrb_to_str` just checks type, no conversion.
 2019-08-07 16:20:40 +09:00
Yukihiro "Matz" Matsumoto 98fc887cb3 Reorganize mrb_string_value_cstr and related functions. 
`mrb_string_value_cstr` and `mrb_string_value_len`: obsolete
`mrb_string_cstr`: new function to retrieve NULL terminated C string
`RSTRING_CSTR`: wrapper macro of `mrb_string_cstr`

Yukihiro "Matz" Matsumoto 6f67fddb87 Fix FIXABLE_FLOAT() on MRB_INT64; ref #4566 
Normal `TYPED_FIXABLE(f,mrb_float)` does not work on 64bit int from
casting problems. The new approach works well, but assumes two's
complement and IEEE-754 floating point numbers.

KOBAYASHI Shuji f9bf2d9d8e Read/write MRB_STR_ASCII flag only when MRB_UTF8_STRING is defined 2019-07-05 22:19:31 +09:00
Yukihiro "Matz" Matsumoto 991bdd4ed7 Rename MRB_STR_NO_UTF to 'MRB_STR_ASCII`; close #4550 
In #4550, @shuuji proposed the name name `MRB_STR_NO_MULTI_BYTE` for
more precise description. Although I agree that the name name is
correct, but the flag means the string does not contain multi byte UTF-8
characters, i.e. all characters fit in the range of ASCII.

KOBAYASHI Shuji 75df13a973 Fix String#byteslice with MRB_UTF8_STRING and some edge cases 
Example:

  $ bin/mruby -e '
    p "あa".byteslice(1)
    p "bar".byteslice(3)
    p "bar".byteslice(4..0)
  '

  Before this patch:

    "a"
    ""
    RangeError (4..0 out of range)

  After this patch (same as Ruby):

    "\x81"
    nil
