It would be a relatively frequent case. It is still slower than
`float * float` because `*` has a dedicated VM instruction (opt_mult),
though.

This limit was introduced on Nov 20 1996
in 554b989ba1623b9f6a0b76f00824c83a23fbcbc1
Apparently to protect from a buffer overflow:
* eval.c (f_missing): オブジェクトの文字列表現が長すぎる時バッファ
を書き潰していた
However I tested that path with very large strings
and it works fine.

We thought this change was an oversight in the latter commit.
Without this change, the test fails like:
$ make test-all TESTS="../test/ruby/test_process.rb -n test_exec_failure_leaves_no_child" RUN_OPTS="--jit"
...

Note: Backporting shouldn't modify object.h and instead can use

It turned out that the pdb corruption happens on Visual Studio 2015 as
well.

Fix https://github.com/ruby/ruby/runs/636020145 without skipping too
many tests.
It seems that .c -> .o with debug flags and .o -> .so without debug
flags did not generate .dSYM but now .c -> .so with debug flags seems to
generate a .dSYM directory. As --jit-debug should not be used by normal
users, let me skip implementing the removal for now.

because we support JIT compaction on it
|
|
Running C compiler for JIT compaction inside a critical section may lock
main thread for a long time when it triggers GC. As I'm planning to
increase this duration a bit, I'd like to make sure this doesn't stop
the world.
For now, I chose to give up unloading units when it's during JIT
compaction, assuming other calls may unload them later.

Revert 9948addda67f4b7a6e3575f1eba9025f998811d2.
It is now discussed in https://bugs.ruby-lang.org/issues/16814, and an
assert is added with a217d3cedce3f5aa5c27a1ce6c72b65ec37da057.
It would be good to give it a try.

Since it is impossible to detect stack overflow of C functions robustly,
the test is a bit unreasonable.

This fixes `RB_FL_TEST_RAW:"RB_FL_ABLE(obj)"` assertion failure

result report of s390x-linux useful, let's skip it until the test is
improved to be more stable.

The same bug as 8355a99883 existed in attr_reader too.
|
|
We started to use fastpath on invokesuper when a method is not refinements
since 5c27681813, but we shouldn't have used fastpath for attr_writer either.
`cc->aux_.attr_index` is for an actual receiver class, while we store
its superclass in `cc->klass` and therefore there's no way to properly
invalidate attr_writer's inline cache when it's called by super.
[Bug #16785]
I suspect the same bug also exists in attr_reader. I'll address that in
another commit.
