Yukihiro "Matz" Matsumoto b98bf36a15 Use mrb_str_inspect instead of mrb_str_dup; fix #4678 2019-09-12 17:15:55 +09:00
Yukihiro "Matz" Matsumoto ec3aeede20 Move String#{getbyte,setbyte,byteslice} to the core; #4696 
Unlike CRuby, there's no way to process strings byte-wise by core
methods because there's no per string encoding in mruby, so that
we moved 3 byte-wise operation methods from `mruby-string-ext` gem.

dearblue 311d867deb Fix mrb_vformat() crashes with MRB_INT16 
If `MRB_INT16` is specified, the variable length argument `mrb_int` is
converted to `int`.

Yukihiro "Matz" Matsumoto 9d08025b8b Revert part of #4225 
Since in mruby, Integer and Float interchange frequently (mostly on
overflow), so adding explicit `.0` can cause problems sometimes.

For example:

https://github.com/pepabo/mruby-msd/pull/13
https://github.com/mattn/mruby-json/pull/42

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`.

KOBAYASHI Shuji a84ab12735 Prioritize embedded string over nofree (or normal) string 
Prioritize embedded string in the following functions:

- `str_new_static`
- `str_new`
- `mrb_str_new_capa`
- `mrb_str_pool`

The reasons are as follows:

- Consistency with `mrb_str_byte_subseq` and `str_replace`.
- Memory locality increases and may be slightly faster.
- No conversion cost to embedded string when modifying the string.

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.

KOBAYASHI Shuji 9832e91304 SHARED/FSHARED string is not required when sharing NOFREE string 
I think the string buffer of NOFREE string always exists and does not need
to be released, so it can be shared as another NOFREE string.

Also changed the `mrb_shared_string` field order so that eliminate padding if
`int` and `mrb_int` sizes are less than pointer size.

Yukihiro "Matz" Matsumoto 06c7ff0666 Avoid creating unnecessary empty arrays on splat. 
But this changes requires `OP_ARYCAT` and `OP_ARYPUSH` to accept `nil`
as their first operand. Alternative VMs (e.g. `mruby/c`) that understand
mruby bytecode need to be updated.
