Since these files are written in a wide character encoding, stop at
first NUL byte and are actually empty. ASCII-incompatible encodings
have never been supported as source encoding.
The following code produces two NameErrors respectively
and they are independent, but the second one can show
`private constant` message because of first NameError.
```ruby
class C
class PrivateClass; end
private_constant :PrivateClass
end
begin
eval('class C::PrivateClass; end')
rescue => e
p e
end
begin
Object.const_get 'Foo'
rescue => e
p e
end
#<NameError: private constant C::PrivateClass referenced>
#<NameError: private constant C::Foo referenced>
#=> should be #<NameError: uninitialized constant Foo>
```
It fails the test-all tests with
`make test-all TESTS='ruby/class ruby/parse --seed=58891 -v`.
The reason is clear miss from https://github.com/ruby/ruby/commit/7387c08373a
* Refactor Regexp#match cache implementation
Improved variable and function names
Fixed [Bug 19537] (Maybe fixed in https://github.com/ruby/ruby/pull/7694)
* Add a comment of the glossary for "match cache"
* Skip to reset match cache when no cache point on null check
This commit introduces a new instruction `opt_newarray_send` which is
used when there is an array literal followed by either the `hash`,
`min`, or `max` method.
```
[a, b, c].hash
```
Will emit an `opt_newarray_send` instruction. This instruction falls
back to a method call if the "interested" method has been monkey
patched.
Here are some examples of the instructions generated:
```
$ ./miniruby --dump=insns -e '[@a, @b].max'
== disasm: #<ISeq:<main>@-e:1 (1,0)-(1,12)> (catch: FALSE)
0000 getinstancevariable :@a, <is:0> ( 1)[Li]
0003 getinstancevariable :@b, <is:1>
0006 opt_newarray_send 2, :max
0009 leave
$ ./miniruby --dump=insns -e '[@a, @b].min'
== disasm: #<ISeq:<main>@-e:1 (1,0)-(1,12)> (catch: FALSE)
0000 getinstancevariable :@a, <is:0> ( 1)[Li]
0003 getinstancevariable :@b, <is:1>
0006 opt_newarray_send 2, :min
0009 leave
$ ./miniruby --dump=insns -e '[@a, @b].hash'
== disasm: #<ISeq:<main>@-e:1 (1,0)-(1,13)> (catch: FALSE)
0000 getinstancevariable :@a, <is:0> ( 1)[Li]
0003 getinstancevariable :@b, <is:1>
0006 opt_newarray_send 2, :hash
0009 leave
```
[Feature #18897] [ruby-core:109147]

During compaction we must fix up shapes on objects who were extended but
then became embedded. `rb_shape_traverse_from_new_root` is supposed to
walk shape trees looking for a matching shape. When a shape has a
"single child" we weren't returning NULL when the edge names didn't
match.
In the case of a single outgoing edge, this patch returns NULL when the
child edge name doesn't match (similar to the case when a shape has a
hash of outgoing edges)
yjit-trace-exits appends a synthetic sample for the instruction being
exited, but we didn't increment the size of the stack. Fixing this count
correctly lets us successfully generate a flamegraph from the exits.
I also replaced the line number for instructions with 0, as I don't
think the previous value had meaning.
