Yukihiro "Matz" Matsumoto cb3a6dd168 ISO C99 doesn't support unnamed unions; fix #5354 2021-03-08 11:50:52 +09:00
Yukihiro "Matz" Matsumoto b64ec814d6 Fix a signed shift bug on 32 bit platforms; ref e1c9e7e 2021-01-12 16:26:05 +09:00
Yukihiro "Matz" Matsumoto 9fbf0ef886 Refactoring integer ranges. 
- Remove `mrb_ssize`
- Fix `MRB_FIXNUM_{MIN,MAX}` to 32 bits on `MRB_NAN_BOXING`
 2020-11-17 12:41:10 +09:00
Yukihiro "Matz" Matsumoto 3107d1caae Allow int size combinations for MRB_WORD_BOXING. 
- `MRB_64BIT` and `MRB_INT32`
- `MRB_32BIT` and `MRB_INT64`
 2020-11-16 22:49:55 +09:00
KOBAYASHI Shuji 8a019106c0 Use uintptr_t instead of unsigned long in include/mruby/boxing_word.h 
`mrb_bool`  on LLP64 environment seems to become false if, for example,
`mrb_value` is a pointer whose lower 32 bits are 0.
 2020-11-16 16:04:05 +09:00
dearblue 926ec1dc7e Define mrb_value in struct for Word/NaN boxing 
This is to make it possible to distinguish between `mrb_value` and `mrb_sym` in C++ "Function overloading" and C11 "Generic selection".
 2020-11-08 14:14:00 +09:00
Yukihiro "Matz" Matsumoto 9b8e5658ce Fix integer casting on 64 bit platforms. 
On platforms where `sizeof(long)` is 4, casting `(long)` can lose data
or sign information.

Yukihiro "Matz" Matsumoto 2b188ed8a1 Reorganize Integer system. 
- Integrate `Fixnum` and `Integer`
- Remove `Integral`
- `int / int -> int`
- Replace `mrb_fixnum()` to `mrb_int()`
- Replace `mrb_fixnum_value()` to `mrb_int_value()`.
- Use `mrb_integer_p()` instead of `mrb_fixnum_p()`
 2020-10-12 18:19:54 +09:00
Yukihiro "Matz" Matsumoto 5a7cbebc8a Remove MRB_NO_FLOAT_INLINE and MRB_WBOX_FLOAT_INLINE configuration. 
They are not used from the beginning.
 2020-10-12 16:21:49 +09:00
Yukihiro "Matz" Matsumoto 55163a8a0a Rename MRB_TT_FIXNUM to MRB_TT_INTEGER. 
We still have `#define MRB_TT_FIXNUM MRB_TT_INTEGER` for compatibility.
 2020-10-12 16:21:47 +09:00
Yukihiro "Matz" Matsumoto 8a87549315 Rename float configuration option names. 
- `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.
 2020-10-12 16:21:40 +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 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 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 f93dffb5ee Remove unused MRB_TT_FILE. 2020-06-15 07:47:22 +09:00
dearblue d0501c69b0 Fix MRB_TT_CPTR object with MRB_NAN_BOXING 
Previously, if `MRB_NAN_BOXING` is defined, for example,
`mrb_cptr_value()` could not keep an odd address.

If it is `MRB_32BIT`, it can be embedded in `NaN` as it is.

If it is `MRB_64BIT`, some operations are shared with `MRB_WORD_BOXING`.
In this case, the MRB_API function `mrb_nan_boxing_cptr_value()` is
defined.

Yukihiro "Matz" Matsumoto ff57c0278f Remove broken MRB_INT16 configuration option. 2020-01-15 21:32:00 +09:00
KOBAYASHI Shuji a53f28275e Fix MRB_FIXNUM_SHIFT with MRB_WORD_BOXING, MRB_INT32 and MRB_64BIT 
### Example

  ```ruby
  # example.rb
  max32 = 2**30 - 1 + 2**30
  min32 = -max32-1
  [max32, max32+1, min32, min32-1].each{|n| p [n, n.class]}
  ```

#### Before this patch:

  ```
  $ bin/mruby example.rb
  [2147483647, Float]
  [2147483648, Float]
  [-2147483648, Float]
  [-2147483649, Float]
  ```

#### After this patch:

  ```
  $ bin/mruby example.rb
  [2147483647, Fixnum]
  [2147483648, Float]
  [-2147483648, Fixnum]
  [-2147483649, Float]
  ```

KOBAYASHI Shuji 375c1ebc41 Rename BITSIZE to BIT and BIT to BIT_POS for consistency 
The bit width terminology is unified to `BIT` according to `MRB_INT_BIT`
and `CHAR_BIT`. Also the bit position terminology is unified to `BIT_POS`.
 2019-11-23 20:40:23 +09:00
KOBAYASHI Shuji feaf80d899 Use type predicate macros instead of mrb_type if possible 
For efficiency with `MRB_WORD_BOXING` (implement type predicate macros for
all `enum mrb_vtype`).
 2019-09-26 22:23:27 +09:00
KOBAYASHI Shuji 5dda4f5da3 Implement all type predicate macros for MRB_WORD_BOXING 
The default implementations of type predicate macros use `mrb_type`.
But `mrb_type` with `MRB_WORD_BOXING` isn't very efficient, so the new
implementations avoid `mrb_type`.
 2019-09-22 22:36:12 +09:00
KOBAYASHI Shuji 7fcda585bc Refactor mrb_type in include/mruby/boxing_word.h 2019-09-15 18:11:16 +09:00
KOBAYASHI Shuji d47bd0a2cd Optimize mrb_bool() with MRB_WORD_BOXING 2019-09-08 12:17:25 +09:00
KOBAYASHI Shuji 17c53040ab Increase symbol bit size on 32-bit mode with MRB_WORD_BOXING 
This change increases the max length of lower inline symbols to 5 bytes.
 2019-09-07 21:38:11 +09:00
KOBAYASHI Shuji 19e2cc187b Avoid bit fields in mrb_value; ref b2c3d88f 
The changes at b2c3d88f were inappropriate because the memory layout of bit
fields are implementation defined. Therefor, I fixed it not to use bit
fields.
 2019-09-06 13:24:35 +09:00
KOBAYASHI Shuji b2c3d88fbf Implement mrb_immediate_p macro for MRB_WORD_BOXING 
The default implementation of `mrb_immediate_p` uses `mrb_type`. However,
in `MRB_WORD_BOXING`, `mrb_type` has many branches and is inefficient, so
provide an implementation that does not use `mrb_type`.

David Siaw b5299b1c58 fix up documentation for values 2019-08-18 20:12:44 +09:00
KOBAYASHI Shuji 4d9d6faf0d Remove unneeded statement in SET_OBJ_VALUE with boxing_word.h 
`(r).value.bp` and `v` have the same value due to assignment of the line
preceding the removed line.

Yukihiro "Matz" Matsumoto 49cb149033 Merge pull request #4391 from dearblue/inlines 
Change modifier to `MRB_INLINE` from `static inline`
 2019-04-22 21:17:27 +09:00
KOBAYASHI Shuji b212050026 Expand BOXWORD_SET_VALUE() macro in include/mruby/boxing_word.h 
In `SET_OBJ_VALUE()`, branch isn't removed because `switch` condition isn't
constant expression.

Yukihiro "Matz" Matsumoto 9e40586d43 Add cast to mrb_int in mrb_fixnum() when MRB_WORD_BOXING. 
Without this cast, `long int:63` can cause warnings.

Yukihiro "Matz" Matsumoto 51d7a69ab0 Clear (o).w first for MRB_WORD_BOXING; ref #3396 2017-01-25 11:07:57 +09:00

cremno 4c868a9562 remove SET_PROC_VALUE() macro 
It isn't used anymore since the #2791 merge. It's also unlikely to be
needed again as it wasn't before (its usage was unnecessary).
