| 2020-10-12 | Extended mruby binary format | dearblue | |
| The catch handler table is combined with iseq block. This is to prevent the structure from growing by adding a field for the catch handler table to the `mrb_irep` structure. "iseq block" and "catch handler table": [number of catch handler table (2 bytes)] [number of byte code (4 bytes)] [iseq (any bytes)] [catch handlers (multiple of 7 bytes)] catch handler: [catch type (1 byte)] [begin offset (2 bytes)] [end offset (2 bytes)] [target offset (2 bytes)] catch type: enum mrb_catch_type (0 = rescue, 1 = ensure) begin offset: Includes the specified instruction address end offset: Does not include the specified instruction address target offset: replaces pc with the specified instruction address This table is not expanded by `read_irep_record_1()`. The necessary elements are expanded one by one when used. | |||
| 2020-10-12 | Initialize `kdict` in `OP_ENTER` in `vm.c`. | Yukihiro "Matz" Matsumoto | |
| 2020-10-12 | Rename `union mrb_value` to `union mrb_value_`. | Yukihiro "Matz" Matsumoto | |
| Since some compiler complains when we `typedef` `mrb_value`. | |||
| 2020-10-12 | Simplify `mrb_value` structure for `MRB_WORD_BOXING`. | Yukihiro "Matz" Matsumoto | |
| 2020-10-12 | Remove `mc_clear_by_id`. | Yukihiro "Matz" Matsumoto | |
| Clearing all method cache using `memset` is faster than conditional clear by method id. | |||
| 2020-10-12 | Do not call `mrb_mc_clear_by_class` at `mrb` finalization. | Yukihiro "Matz" Matsumoto | |
| 2020-10-12 | Use `memset()` to clear method cache. | Yukihiro "Matz" Matsumoto | |
| 2020-10-12 | Add `const` specifier to `cipush()`; ref #5052 | Yukihiro "Matz" Matsumoto | |
| 2020-10-12 | Use hash table instead of segment list for instance variables. | Yukihiro "Matz" Matsumoto | |
| 2020-10-12 | Rename `mrb_hash_modify` to `hash_modify`. | Yukihiro "Matz" Matsumoto | |
| Since it's an internal static function. | |||
| 2020-10-12 | Use `mrb_field_write_barrier` instead of `mrb_write_barrier` for `push`. | Yukihiro "Matz" Matsumoto | |
| When the array is very big, the simpler `mrb_write_barrier` causes calling `gc_mark_children` for big arrays repeatedly. That would hinder performance very badly. | |||
| 2020-10-12 | Check `lv` before printing local variable names. | Yukihiro "Matz" Matsumoto | |
| 2020-10-12 | Fix the bug by the combination with `MRB_64BIT` and `MRB_INT32`. | Yukihiro "Matz" Matsumoto | |
| Which is caused by `MRB_NAN_BOXING`. | |||
| 2020-10-12 | You don't need to keep index in local variables info in `irep`. | Yukihiro "Matz" Matsumoto | |
| 2020-10-12 | Enable method cache by default. | Yukihiro "Matz" Matsumoto | |
| 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 | Call `#initialize_copy` from `init_copy` only if it's redefined. | Yukihiro "Matz" Matsumoto | |
| 2020-10-12 | Skip `mrb_get_args()` in `mrb_ary_push()`. | Yukihiro "Matz" Matsumoto | |
| 2020-10-12 | Split `MRB_BINARY_FORMAT` to major and minor. | Yukihiro "Matz" Matsumoto | |
| The minor versions should be upper compatible. So mere opcode, section addition can be done without breaking compiled binary. | |||
| 2020-10-12 | Remove `OP_EXT[123]` from operands. | Yukihiro "Matz" Matsumoto | |
| 2020-10-12 | Constify `irep` struct for `Class#new`. | Yukihiro "Matz" Matsumoto | |
| 2020-10-12 | Add `const` qualifier to generated `Proc` structures. | Yukihiro "Matz" Matsumoto | |
| 2020-10-12 | Should not mark red (i.e. ROM allocated) objects. | Yukihiro "Matz" Matsumoto | |
| 2020-10-12 | Use `int` instead of `mrb_int` for arena index. | Yukihiro "Matz" Matsumoto | |
| 2020-10-12 | Use `%u` instead of `%d` to dump symbol IDs. | Yukihiro "Matz" Matsumoto | |
| 2020-10-12 | Avoid use of designated initializer for the sake of `cxx_abi`. | Yukihiro "Matz" Matsumoto | |
| 2020-10-12 | Add casts to silence warnings. | Yukihiro "Matz" Matsumoto | |
| 2020-10-12 | Clarify the use of `MRB_64BIT` and `MRB_INT64` in `dump.c` and `load.c`. | Yukihiro "Matz" Matsumoto | |
| - `MRB_64BIT`: the size of a pointer is 64 bits - `MRB_INT64`: the size of `mrb_int` is 64 bits | |||
| 2020-10-12 | Fix `dump.c` for `MRB_INT32` env. | Yukihiro "Matz" Matsumoto | |
| 2020-10-12 | Enable NUL (`\0`) again. | Yukihiro "Matz" Matsumoto | |
| 2020-10-12 | Generate C struct from `irep` instead of binary dump. | Yukihiro "Matz" Matsumoto | |
| 2020-10-12 | Generate C source file to represent `mrb_irep` structures. | Yukihiro "Matz" Matsumoto | |
| 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 | Removed alignment pragma from `-B` output from `mrbc`. | Yukihiro "Matz" Matsumoto | |
| We no longer need 4 bytes alignment after we moved to the byte oriented instructions. | |||
| 2020-10-12 | Replace entire `irep->pool`. | Yukihiro "Matz" Matsumoto | |
| 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 | Rename `struct mrb_locals` to `struct mrb_lvinfo`. | Yukihiro "Matz" Matsumoto | |
| That stands for "local variable information". | |||
| 2020-10-12 | Add `irep` C struct dump from `mrbc` with `-S` option. | Yukihiro "Matz" Matsumoto | |
| But we need more work: - recursive `irep` dump (`irep->reps`) - pool values dump (`irep->pool`) | |||
| 2020-10-12 | Avoid use of designated initializers to generate `irep` struct. | Yukihiro "Matz" Matsumoto | |
| Since it's not supported on VC without `/std:c++latest`. That means it doesn't work for `cxx_api` build on Windows VC. | |||
| 2020-10-12 | Make `call_irep` static. | Yukihiro "Matz" Matsumoto | |
| 2020-10-12 | Use `static const struct mrb_irep each_irep` to ininitalize `each`. | Yukihiro "Matz" Matsumoto | |
| 2020-10-12 | Stringify non C identifier symbols to stop macro errors by old gcc. | Yukihiro "Matz" Matsumoto | |
| 2020-10-12 | Constify `irep` members. | Yukihiro "Matz" Matsumoto | |
| - `pool` - `syms` - `reps` | |||
| 2020-10-12 | Change the arguments of following implicit conversion functions: | Yukihiro "Matz" Matsumoto | |
| - `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 | Use functions that take symbols to reduce string litrals in C. | Yukihiro "Matz" Matsumoto | |
| 2020-10-12 | Provide functions that take symbols instead of `const char*`. | Yukihiro "Matz" Matsumoto | |
| - 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_get_id - mrb_class_defined_under_id - mrb_class_get_under_id - mrb_module_get_id - mrb_module_get_under_id - mrb_define_class_under_id - mrb_define_module_under_id - mrb_exc_get_id | |||
| 2020-10-12 | Add functions that take symbols as arguments. | Yukihiro "Matz" Matsumoto | |
| - : | |||
| 2020-10-12 | Use `mrb_funcall_id()` extensively. | Yukihiro "Matz" Matsumoto | |
| Except for support files e.g. `mruby-test/driver.c`, which are not target of symbol collection via `rake gensym`. | |||
| 2020-10-12 | Define a new function `mrb_funcall_id()`. | Yukihiro "Matz" Matsumoto | |
| `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 | Use `MRB_QSYM()` instead of `MRB_OPSYM()`. | Yukihiro "Matz" Matsumoto | |
| 2020-10-12 | Rename `MRB_OPSYM()` to `MRB_QSYM()`. | Yukihiro "Matz" Matsumoto | |
| 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 | Use `MRB_OPSYM()` instead of `mrb_intern_lit()`. | Yukihiro "Matz" Matsumoto | |
| 2020-10-12 | Create `MRB_OPSYM()` macro to refer symbols corresponding operators. | Yukihiro "Matz" Matsumoto | |
| For example, `MRB_OPSYM(add)` refers a symbol for `+`. | |||
