This gem uses C99 `_Complex` features. You need a C compiler that
supports `_Complex` to enable this gem. All `gcc`, `clang`, `VC` support
`_Complex` so there should not be a big problem.
|
|
|
|
* Use `class_eval` instead of `instance_eval`.
* Reduce `class_eval` calls
* define `Numeric#i`
* undefine `Complex#i`

Check if `.pi` build rules are defined
|
|
`.pi` files are created for `.o` files that `build.products` depends on, but
an error will occur if the build rule is unknown, so add a check.
I don't think this situation would normally arise. However, in
`mattn/mruby-onig-regexp`, when using bundled onigmo, onigmo's `.o` files
are added to dependency of `libmruby.a` in the second and subsequent builds,
and mruby does not know the build rule, so the following error had occured.
```console
rake aborted!
Don't know how to build task '/mruby/build/host/mrbgems/mruby-onig-regexp/onigmo-6.2.0/libonig_objs/ascii.pi' (See the list of available tasks with `rake --tasks`)
```

shuujii/fix-breakage-where-builds-except-host-dont-refer-mrbc-in-host
Fix breakage where builds except `host` don't refer` mrbc` in `host`
|
|
Build error occurred under the following conditions.
* `host` build is presym enabled and unspecified `mruby-bin-mrbc` gem.
* Build except `host` unspecified `mruby-bin-mrbc` gem and mrbcfile.
### Example
#### Build configuration
```ruby
MRuby::Build.new{|conf| conf.toolchain}
MRuby::Build.new("host2"){|conf| conf.toolchain}
```
#### Error
```console
rake aborted!
external mrbc or mruby-bin-mrbc gem in current('host2') or 'host' build is required

We don't want to increase number of files that should be compiled by C++
compiler when `enable_cxx_exception` is turned on.
|
|
|
|
We have introduced following new instructions.
* `OP_LAMBDA16`
* `OP_BLOCK16`
* `OP_METHOD16`
* `OP_EXEC16`
Each instruction uses 16 bits operand for `reps` index. Since new
instructions are added, `mruby/c` VM should be updated.
Due to new instructions, dump format compatibility is lost, we have
increased `RITE_BINARY_MAJOR_VER`.
In addition, we have decreased the size of `refcnt` in `mrb_irep` from
`uint32_t` to `uint16_t`, which is reasonably big enough.
|
|
In addition, stop eager allocation of `mt` table.
|
|
Introduced `MRB_PRESYM_INIT_SYMBOLS()`

shuujii/use-mrb_open_core-instead-of-mrb_open--in-mrbc
Use `mrb_open_core()` instead of `mrb_open()` in `mrbc`
|
|
Remove unnecessary `ci0` variables; ref #5272
|
|
|
|
Remove unnecessary configuration macros; ref #5060
|
|
The `init_SYMBOLS()` function implicitly defined in `MRB_PRESYM_DEFINE_VAR_AND_INITER()` requires some familiarity when trying to find it from the caller.
By introducing `MRB_PRESYM_INIT_SYMBOLS()`, it is possible to find directly from the identifier.
|
|
|
|
The following macros will be removed:
- `ENSURE_STACK_INIT_SIZE`
- `RESCUE_STACK_INIT_SIZE`
- `MRB_ECALL_DEPTH_MAX`

Build internal mrbc in an internal directory

Fixed `String#unpack` to handle the highest range of integer values
|

|

This is a correction based on the review by @matz.

Previously, problems occurred when the `fixnum` was exceeded.
- 32-bit cpu mode with `MRB_WORD_BOXING` and `MRB_INT32`:
```console
% bin/mruby -e 'p [0x7fffffff].pack("N").unpack("N")'
trace (most recent call last):
-e:1: cannot unpack to Integer: 2147483647 (RangeError)
```
- 64-bit cpu mode with `MRB_WORD_BOXING` and `MRB_INT64`:
```console
% bin/mruby -e 'p [0x7fffffff_ffffffff].pack("q").unpack("q")'
trace (most recent call last):
-e:1: cannot unpack to Integer: 9223372036854775807 (RangeError)
```

Raise SystemStackError if mruby VM stack expansion fails
|
|
Check first `0` when converting symbols into strings
|
|
|
|
This was because it caused `SIGSEGV` when `mruby -v` displayed an unnamed variable.
```console
% bin/mruby -ve 'call { |(a, b)| }'
...SNIP...
irep 0x8007d0050 nregs=3 nlocals=1 pools=0 syms=1 reps=1 iseq=12

1 005 OP_SENDB R1 :call 0
1 009 OP_RETURN R1
1 011 OP_STOP
irep 0x8007d00a0 nregs=6 nlocals=5 pools=0 syms=0 reps=0 iseq=29
local variable names:

Refine `preprocess_options`; ref d95ffb036
|
|
|
|
If we modify an option that may have been specified by users, we may
make unintended changes, so it is better not to modify it as much as
possible, IMO.
|
|
|
|
It's for internal use. Please use `conf.disable_presym`.

shuujii/split-presym_table-for-reduced-program-size
Split `presym_table` for reduced program size
|
|
Because a structure that is an element of `presym_table` has padding, split
it into individual arrays for name and length.
