KOBAYASHI Shuji ae530d89c4 Remove unused node type in codegen() 2019-09-28 15:15:31 +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`).

Yukihiro "Matz" Matsumoto a365f9a67d Rename symbol-to-string functions; close #4684 
* mrb_sym2name -> mrb_sym_name
* mrb_sym2name_len -> mrb_sym_name_len
* mrb_sym2str -> mrb_sym_str

Yukihiro "Matz" Matsumoto 49967097ed Skip nil? method call in if conditionals. 
Compile `if expr.nil?` to use `OP_JMPNIL` instead of calls.

Yukihiro "Matz" Matsumoto 183fb961b3 Fixed a bug in the OP_JMPNOT optimization (13eaff4); fix #4644 2019-08-20 22:01:50 +09:00

Yukihiro "Matz" Matsumoto 13eaff4f9f Remove unnecessary OP_JMPNOT for unless statement. 2019-08-17 12:29:04 +09:00
Yukihiro "Matz" Matsumoto 06c7ff0666 Avoid creating unnecessary empty arrays on splat. 
But this changes requires `OP_ARYCAT` and `OP_ARYPUSH` to accept `nil`
as their first operand. Alternative VMs (e.g. `mruby/c`) that understand
mruby bytecode need to be updated.

KOBAYASHI Shuji 334afb167c Use new specifiers/modifiers of mrb_vfromat() 
The binary sizes (gems are only `mruby-bin-mruby`) are reduced slightly in
my environment than before the introduction of new specifiers/modifiers
(5116789a) with this change.

BTW, I accidentally changed `tasks/toolchains/visualcpp.rake` at #4613,
so I put it back.

dearblue 3f3e4754d9 Fix leaked function symbols 
- `free_heap()` in src/gc.c
- `symhash()` in src/symbol.c
- `no_optimize()` in mrbgems/mruby-compiler/core/codegen.c

Yukihiro "Matz" Matsumoto befdf59e61 Deallocate s->lines in codegen_error; ref #4370 2019-04-12 22:54:25 +09:00
Yukihiro "Matz" Matsumoto 00545fc51d The number of local variables should be less than 1024; fix #4370 
The `env` stores stack length in a 10 bit field.
See `MRB_ENV_STACK_LEN()` macro.

Yukihiro "Matz" Matsumoto 2871d0cdc5 Avoid keeping pointers from mrb_sym2name_len(); fix #4342 
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.

Yukihiro "Matz" Matsumoto 4ccc3f1525 Use key argument register for OP_KEY_P to reduce register use. 2019-02-18 17:25:01 +09:00

Yukihiro "Matz" Matsumoto bdc9de875f Add OP_ENTER to blocks without parameters; fix #4175 
So that `lambda{}.call(1)` raises `ArgumentError` as CRuby does.
Also, fixed junk assignment for `lambda{|;a|p a}.call{}`.

KOBAYASHI Shuji abbc501433 class/module expression with empty body should return nil 
Before:

  p(class A end)          #=> A
  p(class << self; end)   #=> #<Class:#<Object:0x7fdc3880e420>>
  p(module B end)         #=> B

After/Ruby:

  p(class A end)          #=> nil
  p(class << self; end)   #=> nil
  p(module B end)         #=> nil

KOBAYASHI Shuji c8f904b7f5 Fix 0.0 and -0.0 handling. 
Fix the following issue:

    Good:
    $ bin/mruby -e 'p(-0.0)' #=> "-0"

    Bad:
    $ bin/mruby -e 'a=0.0; p(-0.0)' #=> "0"

Yukihiro "Matz" Matsumoto 762f682b80 Allow destructuring in formal arguments. 
e.g.
```
def m(a,(b,c),d); p [a,b,c,d]; end
m(1,[2,3],4)  # => [1,2,3,4]
```

mruby limitation:
Destructured arguments (`b` and `c` in above example) cannot be accessed
from the default expression of optional arguments and keyword arguments,
since actual assignment is done after the evaluation of those default
expressions. Thus:

```
def f(a,(b,c),d=b)
  p [a,b,c,d]
end
f(1,[2,3])
```

raises `NoMethodError` for `b` in mruby.
