dearblue 0d7b4deccf Removed push/pop instructions for rescue/ensure 
`OP_PUSHERR`, `OP_POPERR`, `OP_EPUSH` and `OP_EPOP` are removed.
 2020-10-12 16:21:32 +09:00
dearblue f467b02d45 Extended OP_EXCEPT and OP_RAISE (OP_RAISEIF) instructions 
- `OP_EXCEPT` checks if `mrb->exc` is `NULL`, `MRB_TT_EXCEPTION` or
  `MRB_TT_BREAK`.
  If `mrb->exc` is `NULL`, it will be replaced with `nil`.

- If `OP_RAISE` is `nil`, it does nothing and the immediately
  following instruction is executed (like `OP_NOP`).
  Also, in case of `RBreak` object, it moves to the processing for
  `break`.
  With this change, the instruction name is changed from
  `OP_RAISE` to `OP_RAISEIF`.

dearblue a54a3df32c Extended mruby binary format 
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.

Yukihiro "Matz" Matsumoto 3ad6bbc40c Add target/host-cxx.rb to compile mruby with cxx_abi. 2020-10-12 16:21:31 +09:00
Yukihiro "Matz" Matsumoto 67d92c48b5 Avoid breaking the result array by side-effect in C++. 2020-10-12 16:21:31 +09:00
Yukihiro "Matz" Matsumoto 6fbc03b3a8 Revert 4c001673b 
Probably I misunderstand strict aliasing rule of C++. The fix in
4c001673b was other way around.
 2020-10-12 16:21:30 +09:00
Yukihiro "Matz" Matsumoto 690cafe274 Initialize kdict in OP_ENTER in vm.c. 2020-10-12 16:21:30 +09:00
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 ce372122ed Remove mc_clear_by_id. 
Clearing all method cache using `memset` is faster than conditional
clear by method id.
 2020-10-12 16:21:28 +09:00
Yukihiro "Matz" Matsumoto a733c6e0ea Do not call mrb_mc_clear_by_class at mrb finalization. 2020-10-12 16:21:28 +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 f751c28ca4 Add target/host-m32.rb to compile mruby in 32bit mode. 
Tested only on Linux. You need to install 32bit relate libraries,
e.g. libc6-dev-i386.
 2020-10-12 16:21:27 +09:00
Yukihiro "Matz" Matsumoto 4281429412 Use memset() to clear method cache. 2020-10-12 16:21:27 +09:00
Yukihiro "Matz" Matsumoto 0e50ea90f3 Add const specifier to cipush(); ref #5052 2020-10-12 16:21:26 +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 84a68ca5ae Make sure bintest only works with host target. 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 1eacdae319 Use hash table instead of segment list for instance variables. 2020-10-12 16:21:25 +09:00
Yukihiro "Matz" Matsumoto 59b35250cc Rename mrb_hash_modify to hash_modify. 
Since it's an internal static function.
 2020-10-12 16:21:24 +09:00
Yukihiro "Matz" Matsumoto 2b45d454bc Use mrb_field_write_barrier instead of mrb_write_barrier for push. 
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 16:21:24 +09:00
Yukihiro "Matz" Matsumoto ff0e3bcea6 Check lv before printing local variable names. 2020-10-12 16:21:24 +09:00
Yukihiro "Matz" Matsumoto 8b3f3c0bf3 Fix the bug by the combination with MRB_64BIT and MRB_INT32. 
Which is caused by `MRB_NAN_BOXING`.
 2020-10-12 16:21:23 +09:00
Yukihiro "Matz" Matsumoto cf2aabdad6 Run tests for target/boxing.rb. 2020-10-12 16:21:23 +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 11955ca1a1 Call #initialize_copy from init_copy only if it's redefined. 2020-10-12 16:21:21 +09:00
Yukihiro "Matz" Matsumoto 52dd0a8cd7 Skip mrb_get_args() in mrb_ary_push(). 2020-10-12 16:21:21 +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

Yukihiro "Matz" Matsumoto 6e86e290e4 Rightward-assign by ASSOC. 
[ruby-bugs:15921]
 2020-10-12 16:21:18 +09:00
Yukihiro "Matz" Matsumoto b2398879fa Avoid including limits.h and stdint.h before mruby.h. 
They are included from `mruby.h` anyway, and including it ahead can
cause some errors regarding `INT32_MAX` etc. with C++ compiler.
 2020-10-12 16:21:18 +09:00
Yukihiro "Matz" Matsumoto e01648b86b Stop CXX_ABI test with VisualC++. 
This combination is too hard to support. Difference between C and C++ is
too big with VisualC++. GCC and clang are OK.
