Don't push frame for String#size, String#bytesize, and String#length.
|
|
When the name is `as_*`, the guideline expects the return type to be a
reference type. Also, it's good to have contrast in the naming from
the more dangerous `as usize` cast `IntoUsize` is meant to be preferred
over.
See: https://rust-lang.github.io/api-guidelines/naming.html
|
|
The `as` casts are somewhat dangerous since when the type on either side
change, it silently becomes a lossy conversion. This is why we have
`IntoUsize` as well as other guaranteed lossless conversion utilities
in stdlib. Use them.
For pointers-to-address, `ptr::addr` is more informative.

https://github.com/Shopify/ruby/issues/649
Class vars are a bit more involved than ivars, since we need to get the
class from the cref, so this calls out to `rb_vm_getclassvariable` and
`rb_vm_setclassvariable` like YJIT.

Copy the YJIT simple inliner except for the kwargs bit. It works great!

Previously, when the output register and the base register are the same
in `out = Lea(Mem(out, disp))`, we did
out = disp
out = out + out
Which wasn't the desired `out = out + disp`.
Fixes a SEGV with `--zjit-call-threshold=2` in
`bootstraptest/test_yjit.rb`.

* Handled in cruby_methods.rs because there is no basic operation for Fixnum#^.

This helps ZJIT optimize ~300,000 more sends in ruby-bench's lobsters

The type name bindgen picks for anonymous enums creates desync issues on
the bindgen CI checks.

/src/jit.c:19:5: error: ISO C restricts enumerator values to range of 'int' (4294967295 is too large) [-Werror,-Wpedantic]

```
|
|
This is mostly to see what happens to the loops-times benchmark.
|
|
Since `Send` has a block iseq, I updated `CCallWithFrame` to take an optional `blockiseq` as well, and then generate `CCallWithFrame` for `Send` when the condition is right.

This counts methods that can be folded away to nothing *in addition* to
the already-counted `CCall`.
|
|
Now methods on singleton classes (for example, `new`) get split up into
`String*#new`, `Array*#new`, ... (where the `*` indicates a singleton
class) instead of all looking like `Class#new`.

We have a lot of patchpoint exits on some applications and this helps
pin down why.
|
|
It just returns nil.
|
|
This is only really called a lot in the benchmark harness, as far as I
can tell.
|
|
|
|
* The while loop pattern can be rewritten to be more idiomatic, which
also allows the iterator to no longer be mutable.
|
|
no_rest() trips an assert inside the GC when we allocate with the GC
disabled this way:
(gc_continue) ../src/gc/default/default.c:2029
(newobj_cache_miss+0x128) [0x105040048] ../src/gc/default/default.c:2370
(rb_gc_impl_new_obj+0x7c) [0x105036374] ../src/gc/default/default.c:2482
(newobj_of) ../src/gc.c:995
(rb_method_entry_alloc+0x40) [0x1051e6c64] ../src/vm_method.c:1102
(rb_method_entry_complement_defined_class) ../src/vm_method.c:1180
(prepare_callable_method_entry+0x14c) [0x1051e87b8] ../src/vm_method.c:1728
(callable_method_entry_or_negative+0x1e8) [0x1051e809c] ../src/vm_method.c:1874
It's tries to continue the GC because it was out of space. Looks like
it's not safe to allocate new objects after using
rb_gc_disable_no_rest(); existing usages use it for malloc calls.
