dearblue e5108a6291 Fixed local variables not separated between copied binding objects 
This is because I forgot to implement the `Binding#initialize_copy` method.

Yukihiro "Matz" Matsumoto 517071e3fa codegen.c: order instructions in natural order for loops. 
`while` and `until` generates in `cond` `jmpif` `body` `jmp` order.
It used to be in `jmp` `body` `cond` `jmpif` order.

Yukihiro "Matz" Matsumoto 64358c09d9 codegen.c: labels should be uint32_t. 2021-07-28 23:08:58 +09:00
Yukihiro "Matz" Matsumoto adfd29c1b0 codegen.c: fix loopinfo structure members. 
- `pc0`: `next` destination
- `pc1`: `redo` destination (renamed from `pc2`)
- `pc3`: `break` destination (renamed from `pc3`)

old `pc1` was unused so removed.

Yukihiro "Matz" Matsumoto e81d497155 codegen.c: removed bytecode when the value of while is not used. 2021-07-28 23:08:58 +09:00
Yukihiro "Matz" Matsumoto 2910af0010 codegen.c: fixed a bug when value is taken from while and until. 
```ruby
p ((while true; p 1; break; end))
```

should print `1 nil` but was `1`.

Yukihiro "Matz" Matsumoto 4dda97502b codegen.c: optimize OP_SETUPVAR after OP_MOVE. 2021-07-17 19:51:24 +09:00
Yukihiro "Matz" Matsumoto 70f31d4bb4 codegen.c: add new peephole optimization for OP_MOVE. 
If `OP_MOVE` comes after `OP_GETUPVAR`, you can skip move and redirect
the destination register of `OP_GETUPVAR`.
 2021-07-16 07:55:25 +09:00
Yukihiro "Matz" Matsumoto 1a3564f2f1 codegen.c: add new peephole optimization for OP_GETUPVAR. 
When `OP_GETUPVAR` is generated right after `OP_SETUPVAR`, there is no
need to read the upvar back to the register, e.g.

    3 008 OP_ADDI       R2      1
    3 011 OP_SETUPVAR   R2      1       0
    4 015 OP_GETUPVAR   R2      1       0
    4 019 OP_LOADI_2    R3

`OP_GETUPVAR` at the address `015` is useless. We can skip it like:

    3 008 OP_ADDI       R2      1
    3 011 OP_SETUPVAR   R2      1      0
    4 015 OP_LOADI_2    R3

Yukihiro "Matz" Matsumoto d9a8981c26 vm.c: OP_DEF to push a symbol to a register. 
The code generator no longer need to emit `OP_LOADSYM` after `OP_DEF`.
`doc/opcode.md` is also updated.

Yukihiro "Matz" Matsumoto 99dbcec89c Revert "Remove OP_EXT[123] from operands." 
This reverts commit fd10c72319.

I thought it was OK to restrict index value within 1 byte, but in some
cases index value could be 16 bits (2 bytes). I had several ideas to
address the issue, but reverting `fd10c72` is the easiest way. The
biggest reason is `mruby/c` still supports `OP_EXT[123]`, so that they
don't need any additional work.
