2021-07-29parse.y: revert some changes to be compiled by old `bison`.Yukihiro "Matz" Matsumoto
2021-07-29y.tab.c: remove auto generated `y.tab.c` from repository.Yukihiro "Matz" Matsumoto
It used to be generated in the build, but `bison` required to generation was too hard to install correctly on MacOS and Windows (version mismatch and package maneger issues). This is retry.
2021-07-28codegen.c: labels should be `uint32_t`.Yukihiro "Matz" Matsumoto
2021-07-28codegen.c: fix `loopinfo` structure members.Yukihiro "Matz" Matsumoto
- `pc0`: `next` destination - `pc1`: `redo` destination (renamed from `pc2`) - `pc3`: `break` destination (renamed from `pc3`) old `pc1` was unused so removed.
2021-07-28codegen.c: removed bytecode when the value of `while` is not used.Yukihiro "Matz" Matsumoto
2021-07-28codegen.c: fixed a bug when value is taken from `while` and `until`.Yukihiro "Matz" Matsumoto
```ruby p ((while true; p 1; break; end)) ``` should print `1 nil` but was `1`.
2021-07-26parse.y: fix an integer cast warning.Yukihiro "Matz" Matsumoto
2021-07-26parse.y: `mrb_int_read()` returns `mrb_int` not `unsigned long`.Yukihiro "Matz" Matsumoto
Also, now too big capture group index just gives `nil`, not error.

2021-07-21codegen.c: move `gen_setxv()` after `new_sym()`.Yukihiro "Matz" Matsumoto
2021-07-21codegen.c: introduce `gen_int()` to generate integer instructions.Yukihiro "Matz" Matsumoto
2021-07-21codegen.c: add peephole optimization for `OP_LOADI32` before `OP_MOVE`.Yukihiro "Matz" Matsumoto
2021-07-21codegen.c: add peephole optimization for `OP_LOADI16` before `OP_MOVE`.Yukihiro "Matz" Matsumoto
2021-07-21codegen.c: a new function `get_int_operand`.Yukihiro "Matz" Matsumoto
2021-07-20codegen.c: negative zero equals to positive zero.Yukihiro "Matz" Matsumoto
`OP_LOADI Rn -0` should be `OP_LOADI_0`.
2021-07-20codegen.c: allow `OP_EXT` before `OP_ADDI` and `OP_SUBI`.Yukihiro "Matz" Matsumoto
This is preparation for integer constant folding.
2021-07-19Remove unused prototypes for `mrb_proc_merge_lvar()`; ref #5511Yukihiro "Matz" Matsumoto

2021-07-17codegen.c: optimize variable assignments after `OP_MOVE`.Yukihiro "Matz" Matsumoto
- `OP_SETGV` - `OP_SETIV` - `OP_SETCV` - `OP_SETCONST`
2021-07-17codegen.c: optimize `OP_SETUPVAR` after `OP_MOVE`.Yukihiro "Matz" Matsumoto
2021-07-16codegen.c: add new peephole optimization for `OP_MOVE`.Yukihiro "Matz" Matsumoto
If `OP_MOVE` comes after `OP_GETUPVAR`, you can skip move and redirect the destination register of `OP_GETUPVAR`.
2021-07-16codegen.c: add new peephole optimization for `OP_GETUPVAR`.Yukihiro "Matz" Matsumoto
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

2021-07-04codegen.c: jump address should be generated by `gen_jmpdst()`.Yukihiro "Matz" Matsumoto
2021-07-03vm.c: `OP_DEF` to push a symbol to `a` register.Yukihiro "Matz" Matsumoto
The code generator no longer need to emit `OP_LOADSYM` after `OP_DEF`. `doc/opcode.md` is also updated.
2021-06-30Revert "Remove `OP_EXT[123]` from operands."Yukihiro "Matz" Matsumoto
This reverts commit fd10c7231906ca48cb35892d2a86460004b62249. 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.
2021-06-29string.rb: `upto` to break when the string length is longer than `end`.Yukihiro "Matz" Matsumoto
