2021-07-25Remove redundant include headers.Yukihiro "Matz" Matsumoto
- stdlib.h - stddef.h - stdint.h - stdarg.h - limits.h - float.h
2021-07-12load.c: call `mrb_top_run()` from `mrb_load_proc()`; fix #5504Yukihiro "Matz" Matsumoto
So that the function behave consistently with `mrb_load_proc()`.
2021-07-09debug.h: use `uint8_t` instead of `char` for BER compressed binary.Yukihiro "Matz" Matsumoto
A change in `load.c` is left uncommitted.
2021-07-08debug.c: new debug line information format `mrb_debug_line_packed_map`.Yukihiro "Matz" Matsumoto
It uses BER number compression of delta of instruction positions and line numbers. BER compression is a variable length number representation. * `mrb_debug_line_ary`: array of line numbers represented in `uint16_t`. `[lineno, lineno, ...]` * `mrb_debug_line_flat_map`: array of `mrb_irep_debug_info_line`, which is `struct {uint32_t pos; uint16_t lineno}`, for each line. * `mrb_debug_line_packed_map` [new]: sequence of BER compressed 2 numbers, `pos_delta, lineno_delta`. Deltas are differences from previous values (starting `0`). `line_entry_counts` represents total length of a packed map string for this type.
2021-06-08string.c: make `mrb_str_len_{inum,dbl}()` static.Yukihiro "Matz" Matsumoto
2021-05-20Support load 64-bit integer from mrb format with MRB_32BIT and MRB_INT64KOBAYASHI Shuji
2021-03-12codegen.c: no integer overflow error in `codegen`; close #5376Yukihiro "Matz" Matsumoto
Add new pool value type `IREP_TT_BIGINT` and generate integer overflow error in the VM. In the future, `mruby` will support `Bignum` for integers bigger than `mrb_int` (probably using `mpz`).
2021-03-05Fix load 64-bit integer from mrb format; fix #5369KOBAYASHI Shuji
2021-01-25fix comparison of minor versionHASUMI Hitoshi
2021-01-20Remove CRC16 from dumped mruby binary.Yukihiro "Matz" Matsumoto
`calc_crc_16_ccitt()` consumes a lot of clock cycles in programs like `mrbtest` which loads a lot of dumped binary. Error detection for flaky channels should be done in the higher level. Note: `mruby/c` should be updated to support this change.
2021-01-12Silence Windows warnings (cast and `setmode`).Yukihiro "Matz" Matsumoto
2021-01-10Replace `tempirep` with `RProc`dearblue
Previously I used the `RData` object to avoid a memory leak in `mrb_irep` if `src/load.c` failed. ref: https://github.com/mruby/mruby/pull/4250 commit: f1523d24042ca3416dc5b9be7b3fc220ddaed896 Considering that the `RProc` object will be created in the subsequent process, it is preferable to create the `RProc` object from the beginning. Along with this, the inside of `read_irep()` is replaced with the processing centered on the `RProc` object. The global function that returns the `mrb_irep` pointer is still provided for compatibility.
2020-11-29Change the catch handler address to 32 bitsdearblue
Follow commit 7150c6753933f12a2ba63769fb7b3a44cfcddd3d .
2020-11-26Avoid memory leak when `mrb_read_irep()` fails.Yukihiro "Matz" Matsumoto
2020-11-24Fix compiler errors from `MRB_NO_FLOAT`; #5185Yukihiro "Matz" Matsumoto
Also added `no-float.rb` target in `build_config`.
2020-11-23Fix unintended variable shadowingWataru Ashihara
2020-11-21Rename `MRB_{ENABLE,DISABLE}_` to `MRB_{USE,NO}_`; close #5163KOBAYASHI Shuji
| Previous Name | New Name | |------------------------------|-------------------------| | MRB_ENABLE_ALL_SYMBOLS | MRB_USE_ALL_SYMBOLS | | MRB_ENABLE_SYMBOLL_ALL | MRB_USE_ALL_SYMBOLS | | MRB_ENABLE_CXX_ABI | MRB_USE_CXX_ABI | | MRB_ENABLE_CXX_EXCEPTION | MRB_USE_CXX_EXCEPTION | | MRB_ENABLE_DEBUG_HOOK | MRB_USE_DEBUG_HOOK | | MRB_DISABLE_DIRECT_THREADING | MRB_NO_DIRECT_THREADING | | MRB_DISABLE_STDIO | MRB_NO_STDIO | | ENABLE_LINENOISE | MRB_USE_LINENOISE | | ENABLE_READLINE | MRB_USE_READLINE | | DISABLE_MIRB_UNDERSCORE | MRB_NO_MIRB_UNDERSCORE | | DISABLE_GEMS | MRB_NO_GEMS | * `MRB_ENABLE_SYMBOLL_ALL` seems to be a typo, so it is fixed. * `MRB_` prefix is added to those without. * The previous names can also be used for compatibility.
2020-10-15Fix out of bound access in `parse.y`.Yukihiro "Matz" Matsumoto
2020-10-12Remove the length of `Float' pool from the binary dump.Yukihiro "Matz" Matsumoto
Also fixed the size calculation of `irep` dump, that could cause memory corruption.
2020-10-12Dump/load 16 bits for `ilen` and `slen` in `irep`.Yukihiro "Matz" Matsumoto
Those types are `uint16_t` in definition. Also we no longer need padding for `iseq`.
2020-10-12Don't compare `int' with `size_t` (from `sizeof()`).Yukihiro "Matz" Matsumoto
2020-10-12Change float representation in `mrb` binary files.Yukihiro "Matz" Matsumoto
From human readable (ASCII) string representation to binary dump of IEEE754 in little endian.
2020-10-12Raname `mrb_exc_new_str_lit()` to `mrb_exc_new_lit()`.Yukihiro "Matz" Matsumoto
It uses `mrb_str_new_lit()` internally, but it doesn't need to express it in the name of the function (macro).
2020-10-12Rename float configuration option names.Yukihiro "Matz" Matsumoto
- `MRB_WITHOUT_FLOAT` => `MRB_NO_FLOAT` - `MRB_USE_FLOAT` => `MRB_USE_FLOAT32` The former is to use `USE_XXX` naming convention. The latter is to make sure `float` is 32bit float and not floating point number in general.
2020-10-12Fix typo `_hander` -> `_handler`.Yukihiro "Matz" Matsumoto
2020-10-12Extended mruby binary formatdearblue
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.
2020-10-12You don't need to keep index in local variables info in `irep`.Yukihiro "Matz" Matsumoto
2020-10-12Split `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.
2020-10-12Use `int` instead of `mrb_int` for arena index.Yukihiro "Matz" Matsumoto
2020-10-12Add casts to silence warnings.Yukihiro "Matz" Matsumoto
2020-10-12Clarify 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
2020-10-12Generate C struct from `irep` instead of binary dump.Yukihiro "Matz" Matsumoto
2020-10-12Replace 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
2020-10-12Rename `struct mrb_locals` to `struct mrb_lvinfo`.Yukihiro "Matz" Matsumoto
That stands for "local variable information".
2020-10-12Constify `irep` members.Yukihiro "Matz" Matsumoto
- `pool` - `syms` - `reps`
2020-08-11Fix `mrb_int` and `size_t` combination warnings.Yukihiro "Matz" Matsumoto

Detailes: When generating a backtrace, called `mrb_intern_lit()`, `mrb_str_new_cstr()` and `mrb_obj_iv_set()` function with `exc_debug_info()` function in `src/error.c`. If a `NoMemoryError` exception occurs at this time, the `exc_debug_info()` function will be called again, and in the same way `NoMemoryError` exception raised will result in an infinite loop to occurs stack overflow (and SIGSEGV). commit da7d7f881bbbad9988a3a2b7bad8f2b72ff06bc6 Author: dearblue <[email protected]> Date: Sun Jan 20 12:00:38 2019 +0900 Fix NULL pointer dereference `mrb->nomem_err` when not initialized Add internal functions (not `static`): * `mrb_raise_nomemory()` * `mrb_core_init_abort()`
2020-05-07Remove endian information/flags from compiled binary format.Yukihiro "Matz" Matsumoto
Since `mruby 2.0`, compiled bytecode no longer depends on the endian of the machine.
2020-01-06Refactor `mrb_cstr_to_dbl`; ref #4920Yukihiro "Matz" Matsumoto
2020-01-06Avoid creating temporary objects in `read_irep_record_1`; close #4920Yukihiro "Matz" Matsumoto
The basic idea of this change is from @dearblue. Note: the arguments of `mrb_str_pool()` have changed, but the function is provided for internal use (No `MRB_API`). So basically you don't have to worry about the change.
2019-09-21Rename MRB_USE_ETEXT_EDATA to MRB_USE_LINK_TIME_RO_DATA_P and support lld ↵Fangrui Song
linked programs In lld linked programs, .rodata comes before .text, thus mrb_ro_data_p will return false for strings in .rodata. Change the lower bound from _etext to __ehdr_start to catch these cases. This works for ld.bfd, gold and lld, and it does not have false positives even if .init_array does not exist. Remove the branch that uses _edata: strings in .data can be modified so this is semantically incorrect. Delete the __APPLE__ branch (its manpages say get_etext() and get_edata() are strongly discouraged). .init_array has been adopted by most ELF platforms to supersede .ctors. Neither _etext nor _edata is used, so rename MRB_USE_ETEXT_EDATA to MRB_USE_EHDR_START.

2019-04-01Avoid keeping pointers from `mrb_sym2name_len()`; fix #4342Yukihiro "Matz" Matsumoto
The addresses for packed inline symbols reference `mrb->symbuf` that could be overridden by the later call of `mrb_sym2name_len`. Since file names in call stack information are kept as symbols, keeping the address in the C structures could cause problems like #4342. This changes small incompatible changes in function prototypes: * `mrb_parser_get_filename`: return value changed to `mrb_sym`. * `mrb_debug_get_filename`: add `mrb_state*` as a first argument. * `mrb_debug_get_line`: ditto. I believe above functions are almost internal, and no third-party mrbgem use them.
