Yukihiro "Matz" Matsumoto 4e56e0defc Rename union mrb_value to union mrb_value_. 
Since some compiler complains when we `typedef` `mrb_value`.
 2020-10-12 16:21:30 +09:00
Yukihiro "Matz" Matsumoto 53e46be7e2 Simplify mrb_value structure for MRB_WORD_BOXING. 2020-10-12 16:21:29 +09:00
Yukihiro "Matz" Matsumoto 73e289c54e Simplify mrb_value structure for MRB_NAN_BOXING. 2020-10-12 16:21:29 +09:00
Yukihiro "Matz" Matsumoto 425b142168 Refine MRB_NAN_BOXING on 32bit architecture. 
You don't need pointer tweaking on 32bit architecture, where pointers
fit in 32bit (lower half of mrb_value).
 2020-10-12 16:21:27 +09:00
Yukihiro "Matz" Matsumoto 1eb71b008f Change default boxing scheme from MRB_NO_BOXING. 
On 64bit platforms: `MRB_NAN_BOXING`
On 32bit platforms: `MRB_WORD_BOXING`
On debugging: `MRB_NO_BOXING`
 2020-10-12 16:21:26 +09:00
Yukihiro "Matz" Matsumoto 5e9dc72bc5 Pack mrb_value into uint64_t when MRB_NAN_BOXING. 2020-10-12 16:21:25 +09:00
Yukihiro "Matz" Matsumoto 3d8a38bea4 You don't need to keep index in local variables info in irep. 2020-10-12 16:21:22 +09:00
Yukihiro "Matz" Matsumoto 639946a006 Enable method cache by default. 
Introduced `MRB_NO_METHOD_CACHE` which is inverse of `MRB_METHOD_CACHE`
that should be enabled intestinally. In addition, the default cache is
made bigger (128 -> 256).
 2020-10-12 16:21:22 +09:00
Yukihiro "Matz" Matsumoto 6db0162ec7 Upgrade RITE_VM_VERSION to 0300 (means mruby 3.0). 2020-10-12 16:21:20 +09:00
Yukihiro "Matz" Matsumoto dec34d6c7b Split MRB_BINARY_FORMAT to major and minor. 
The minor versions should be upper compatible. So mere opcode, section
addition can be done without breaking compiled binary.
 2020-10-12 16:21:20 +09:00
Yukihiro "Matz" Matsumoto 8f0ac27196 Update opcode reference and comment. 
- no OP_EXT_ anymore
- OP_LOADI16 in right position
 2020-10-12 16:21:19 +09:00
Yukihiro "Matz" Matsumoto fd10c72319 Remove OP_EXT[123] from operands. 2020-10-12 16:21:19 +09:00
Yukihiro "Matz" Matsumoto ce30a4e04b Add const to irep structure to place data on ROM. 2020-10-12 16:21:16 +09:00
Yukihiro "Matz" Matsumoto 9debf63340 Specify the size of struct RStringEmbed array part. 2020-10-12 16:21:13 +09:00
Yukihiro "Matz" Matsumoto ee111dd175 Clarify the use of MRB_64BIT and MRB_INT64 in dump.c and load.c. 
- `MRB_64BIT`: the size of a pointer is 64 bits
- `MRB_INT64`: the size of `mrb_int` is 64 bits
 2020-10-12 16:21:11 +09:00
Yukihiro "Matz" Matsumoto 52507b1083 Generate C struct from irep instead of binary dump. 2020-10-12 16:21:10 +09:00
Yukihiro "Matz" Matsumoto 7deb41b0e8 Generate C source file to represent mrb_irep structures. 
Type `mrbc -S -B<init> -o<outfile> <rbfiles...>` to generate the C
source code that holds compiled `mrb_irep`.

Appending the following code to the bottom of the generated code,
`mruby` executes the compiled code:

```C
int
main()
{
  mrb_state *mrb = mrb_open();
  struct RProc *p = mrb_proc_new(mrb, &init_irep);
  mrb_vm_run(mrb, p, mrb_top_self(mrb), 0);
  mrb_close(mrb);
  return 0;
}
```

Eventually static compile should use this representation, instead
of `uint8_t` array that holds `mrb` data, so that we can skip
interpreting `mrb` data.
 2020-10-12 16:21:09 +09:00
Yukihiro "Matz" Matsumoto d428fa0c4a Replace entire irep->pool. 
Changes:
- `pool format is completely replaced
  - supported types: `STR`, `INT32`, `INT64`, `FLOAT`
  - `FLOAT` may be replaced by binary representation in the future
- insert `NUL` after string literals in `mrb` files
- `irep->pool` no longer store values in `mrb_value`
- instead it stores in `mrb_pool_value`
- less allocation
- `mrb_irep` can be stored in ROM
 2020-10-12 16:21:08 +09:00
Yukihiro "Matz" Matsumoto daa37be549 Rename struct mrb_locals to struct mrb_lvinfo. 
That stands for "local variable information".
 2020-10-12 16:21:08 +09:00
Yukihiro "Matz" Matsumoto ad15e59cd9 Add irep C struct dump from mrbc with -S option. 
But we need more work:
- recursive `irep` dump (`irep->reps`)
- pool values dump (`irep->pool`)
 2020-10-12 16:21:07 +09:00
Yukihiro "Matz" Matsumoto 029c7c1116 Add const modifier to mrb_irep for code_fetch_hook. 2020-10-12 16:21:05 +09:00
Yukihiro "Matz" Matsumoto 7ab7cadbbb Stringify non C identifier symbols to stop macro errors by old gcc. 2020-10-12 16:21:04 +09:00
Yukihiro "Matz" Matsumoto 5a3e014e49 Constify irep members. 
- `pool`
- `syms`
- `reps`
 2020-10-12 16:21:03 +09:00
Yukihiro "Matz" Matsumoto b67955b8ca Change the arguments of following implicit conversion functions: 
- `mrb_convert_type`
- `mrb_check_convert_type`

Those function no longer take `tname` string representation of desired
type, and take method symbols instead of `const char*` names. This is
incompatible change. I hope no third-party gems use those functions.
 2020-10-12 16:20:59 +09:00
Yukihiro "Matz" Matsumoto 8864c30d16 Provide functions that take symbols instead of const char*. 
- mrb_define_class_id
- mrb_define_module_id
- mrb_define_method_id
- mrb_define_singleton_method_id
- mrb_define_module_function_id
- mrb_define_const_id
- mrb_undef_method_id
- mrb_undef_class_method_id
- mrb_class_defined_id

- mrb_class_defined_under_id
- mrb_class_get_under_id
- mrb_module_get_id

Yukihiro "Matz" Matsumoto fa6a9f6f13 Add functions that take symbols as arguments.

 2020-10-12 16:20:58 +09:00
Yukihiro "Matz" Matsumoto dcd3e5907c Define a new function mrb_funcall_id(). 
`mrb_funcall_id()` takes `mrb_sym` instead of `char*` for a method name.
You can use `MRB_SYM()`/`MRB_QSYM()` to specify the method to call.
 2020-10-12 16:20:57 +09:00
Yukihiro "Matz" Matsumoto 246c76e261 Rename MRB_OPSYM() to MRB_QSYM(). 
Where `QSYM` means quoted symbols, which cannot be represented C
symbols, so specify aliases instead.

- operators: name of the operation, e.g. add for `+`
- predicates: add `_p` suffix instead of `?`
- bang methods: add `_b` suffix instead of `!`
- instance variables: add `a_` prefix instead of `@`
- global variables: add `d_` prefix instead of `@`
- class variables: unsupported; don't use them
 2020-10-12 16:20:53 +09:00
Yukihiro "Matz" Matsumoto 1bcf6d9f3c Create MRB_OPSYM() macro to refer symbols corresponding operators. 
For example, `MRB_OPSYM(add)` refers a symbol for `+`.

Yukihiro "Matz" Matsumoto 97e3c3a5a3 Undefine internal macros in presym.h.

 2020-10-12 16:20:51 +09:00
Yukihiro "Matz" Matsumoto eddd324979 Add MRB_SYM() for inline symbols. 2020-10-12 16:20:41 +09:00
dearblue 57611240a9 Prohibit string changes by "s"/"z" specifier of mrb_get_args() 
- The `s` specifier is a string pointer obtained without performing `mrb_str_modify()`, so it cannot be changed.
- The `z` specifier cannot be changed because it is a string pointer obtained by `RSTRING_CSTR()` which returns `const char *`.

Use normal `static_assert` in `mrb_static_assert` as much as possible
 2020-08-11 22:33:44 +09:00
KOBAYASHI Shuji bab7e9f032 Use normal static_assert in mrb_static_assert as much as possible 
* `_Static_assert` can also be used with `-std=gnu99` on GCC >= 4.6.
* `static_assert` can be used on MSVC.
* `static_assert` can be used even on old G++/Clang++ if
  `__GXX_EXPERIMENTAL_CXX0X__` is defined.
