codegen.c: peephole optimize OP_MOVE after OP_ARRAY or OP_HASH.
...
When the length operand is zero, we don't need `OP_MOVE` but adjust the
destination operand instead.

mruby/ops.h: add new instructions OP_GETIDX and OP_SETIDX.
...
Which represent `obj[int]` and `obj[int]=val` respectively where `obj`
is either `string`, `array` or `hash`, so that index access could be
faster. When `obj` is not assumed type or `R(a+1)` is not integer, the
instructions fallback to method calls.

parse.y: __ENCODING__ should be determined in run-time; fix #5552
...
It used to be compiled to the static string in the compiler. But the
encoding status actually depends on the runtime configuration. A new
method `Kernel#__ENCODING__` is introduced to implement the feature.

codegen.c: unify OP_ARYPUSH and OP_ARYPUSH_N.
...
- `OP_ARYPUSH` now takes operand for the number of pushing elements
- the code generator consume the stack no more than `64` for `mruby/c`
2021-09-19 09:07:20 +09:00

For example, `{p:}` (means `{p:p}`) and `{String:}` (`{String:String}`)

Organize the include of header files
...
- `#include <math.h>` is done in `mruby.h`.
Eliminate the need to worry about the `MRB_NO_FLOAT` macro.
- Include mruby header files before standard header files.
If the standard header file is already placed before `mruby.h`, the standard header file added in the future tends to be placed before `mruby.h`.
This change should some reduce the chances of macros that must be defined becoming undefined in C++ or including problematic header files in a particular mruby build configuration.
