Yukihiro "Matz" Matsumoto 191ee2596c Need to copy argv since it may be reallocated; fix #3500 
The argv for `mrb_yield_with_class()` should not be on mruby stack.
Note the result from `mrb_get_args("*")` is on the stack.

Yukihiro "Matz" Matsumoto 877f43bca5 OP_BLKPUSH is invalid outside of methods; fix #3501 2017-03-13 22:03:31 +09:00
Yukihiro "Matz" Matsumoto 916b8ed5c8 Generate new OP_RESCUE; fix #3487 
The old OP_RESCUE took one operand A, which specifies a class
to match with the exception. The new OP_RESCUE takes tree operands:

A: the register to hold exception
B: the matching exception; the match result will be stored here.
C: the continuation; if C is zero, the exception will be stored to R(A)
   otherwise, the value from R(A) is used as a exception.

Thus,
```ruby
begin
  raise "a"
rescue TypeError
  p 1
rescue RuntimeError
  p 2
end
```
will be compiled as
```
irep 0x557a06667aa0 nregs=4 nlocals=1 pools=1 syms=4 reps=0

```

The new VM can accept old OP_RESCUE. The mruby compatible VM (namely
mruby/c) should be updated to support the new OP_RESCUE behavior.

* enable_cxx_abi (use C++ ABI including exceptions)

Yukihiro "Matz" Matsumoto 1a1f834ade Compile C files by C compiler when C++ files mixed. 
ref #3267 #3470

By this commit, mruby do not use C++ ABI mode unless
you specify explicitly. It compiles C files by C
compilers, with C++ exception enabled when it sees
C++ files in your configured mrbgems.

I haven't tried visualcpp, so please submit an issue
if you see any problem with C++ gems on Windows.
