2019-09-22Implement all type predicate macros for `MRB_WORD_BOXING`KOBAYASHI Shuji
The default implementations of type predicate macros use `mrb_type`. But `mrb_type` with `MRB_WORD_BOXING` isn't very efficient, so the new implementations avoid `mrb_type`.
2019-09-21Rename MRB_USE_ETEXT_EDATA to MRB_USE_LINK_TIME_RO_DATA_P and support lld ↵Fangrui Song
linked programs In lld linked programs, .rodata comes before .text, thus mrb_ro_data_p will return false for strings in .rodata. Change the lower bound from _etext to __ehdr_start to catch these cases. This works for ld.bfd, gold and lld, and it does not have false positives even if .init_array does not exist. Remove the branch that uses _edata: strings in .data can be modified so this is semantically incorrect. Delete the __APPLE__ branch (its manpages say get_etext() and get_edata() are strongly discouraged). .init_array has been adopted by most ELF platforms to supersede .ctors. Neither _etext nor _edata is used, so rename MRB_USE_ETEXT_EDATA to MRB_USE_EHDR_START.
2019-09-16Remove `MRB_METHOD_TABLE_INLINE`.Yukihiro "Matz" Matsumoto
`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.
2019-09-16Raise `ArgumentError` by `aspec` check; ref #4688Yukihiro "Matz" Matsumoto
This is partial `aspec` check that only checks `MRB_ARGS_NONE()`.
2019-09-16Share common definition of `MRB_METHOD_FUNC_FL`.Yukihiro "Matz" Matsumoto
2019-09-16Use bit shifting to pack function pointers to `mrb_method_t`.Yukihiro "Matz" Matsumoto
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.

2019-09-08Optimize `mrb_bool()` with `MRB_WORD_BOXING`KOBAYASHI Shuji
2019-09-07Increase symbol bit size on 32-bit mode with `MRB_WORD_BOXING`KOBAYASHI Shuji
This change increases the max length of lower inline symbols to 5 bytes.
2019-09-06Avoid bit fields in `mrb_value`; ref b2c3d88fKOBAYASHI Shuji
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.

2019-08-31Implement `mrb_immediate_p` macro for `MRB_WORD_BOXING`KOBAYASHI Shuji
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`.

ref: https://github.com/mruby/mruby/pull/4483#issuecomment-498001736 In this configuration, `tt` of `RBreak::val` is set into `RBreak::flags`.
2019-08-20Avoid C++ strict aliasing warning.Yukihiro "Matz" Matsumoto
Based on code proposed by @dearblue to avoid the warning: `dereferencing type-punned pointer will break strict-aliasing rules`.
2019-08-20Use `RBasic` padding for embedded string on 64-bit CPUKOBAYASHI Shuji
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.
2019-08-18Allow external definition of MRB_API macroRyan Lopopolo
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.

2019-08-11`mrb_str_modify_keep_ascii` can embed one more byteKOBAYASHI Shuji
The condition to make an embedded string was incorrect. Because there were several similar codes, extracted into `RSTR_EMBEDDABLE_P` macro.

Contrary to the name, `mrb_to_str` just checks type, no conversion.
2019-08-07Reorganize `mrb_string_value_cstr` and related functions.Yukihiro "Matz" Matsumoto
`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`

2019-07-22Fix `FIXABLE_FLOAT()` on `MRB_INT64`; ref #4566Yukihiro "Matz" Matsumoto
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.
2019-07-17Avoid `MRB_INLINE` for `mrb_str_modify()`; ref #4579Yukihiro "Matz" Matsumoto

2019-07-04Rename `MRB_STR_NO_UTF` to 'MRB_STR_ASCII`; close #4550Yukihiro "Matz" Matsumoto
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.
