KOBAYASHI Shuji 482d0626b8 Remove a trailing space in MRUBY_DESCRIPTION 2019-09-30 21:39:13 +09:00
dearblue 40e8a90e89 Remove unnecessary type mrb_hash_value 
The type `mrb_hash_value` is no longer used by the segmented list
implementation (ref e8dcfe1 and e65d426).

Yukihiro "Matz" Matsumoto bbfd64d01b Add an annotation of the return value from mrb_delete_key; #4737 
The return value from `mrb_delete_key` needs to be protected from GC in
some cases.

Yukihiro "Matz" Matsumoto 5cd6ed4511 Merge pull request #4733 from shuujii/use-type-predicate-macros-instead-of-mrb_type-if-possible

Yukihiro "Matz" Matsumoto d4be545d54 Fixed codedump for human readable symbol format; ref #4684 2019-09-26 23:56:40 +09:00
KOBAYASHI Shuji feaf80d899 Use type predicate macros instead of mrb_type if possible 
For efficiency with `MRB_WORD_BOXING` (implement type predicate macros for
all `enum mrb_vtype`).

Yukihiro "Matz" Matsumoto a365f9a67d Rename symbol-to-string functions; close #4684 
* mrb_sym2name -> mrb_sym_name
* mrb_sym2name_len -> mrb_sym_name_len
* mrb_sym2str -> mrb_sym_str

dearblue 84d9296c05 Use inttypes for snprintf() 2019-09-25 23:28:05 +09:00
KOBAYASHI Shuji 27e8ea4ea2 Remove MRB_TT_HAS_BASIC macro 
The value of `MRB_TT_HAS_BASIC` is meaningless because `MRB_TT_HAS_BASIC` is
no longer used with `MRB_WORD_BOXING` at b2c3d88f.
 2019-09-25 18:17:01 +09:00
KOBAYASHI Shuji 5dda4f5da3 Implement all type predicate macros for MRB_WORD_BOXING 
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`.

Fangrui Song 7f044341f9 Rename MRB_USE_ETEXT_EDATA to MRB_USE_LINK_TIME_RO_DATA_P and support lld 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.

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.
 2019-09-16 11:14:13 +09:00
Yukihiro "Matz" Matsumoto 30f3787248 Raise ArgumentError by aspec check; ref #4688 
This is partial `aspec` check that only checks `MRB_ARGS_NONE()`.
 2019-09-16 10:50:31 +09:00
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 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.
 2019-09-07 21:38:11 +09:00
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 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 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.
