Noah Gibbs be06112d48 Fix changes from rebase 2021-10-20 18:19:42 -04:00
Alan Wu f36a5a98c0 style: line break before "else" 2021-10-20 18:19:41 -04:00
Alan Wu ec4998bd69 style: switch statements indent 
Case labels get half an indent and the opening brace is on the same line
as "switch".

Alan Wu 5c15850ea6 Use jit_guard_known_klass() for hashes in opt_aref 
The old heap object check is not as efficient as the one in
jit_guard_known_klass(). Also, the old code saves cfp->sp after popping
the operands off the stack, which might cause the operands to be not
marked by the GC in some circumstances.

Alan Wu a09adac2d7 Add specialization for String#to_s on plain strings 
When calling "to_s" on an instance of String, the method simply returns
self. In this situation most of the work comes from setting up the
method call. It turns out that both railsbench and liquid-render do this
a lot.

When generating code for opt_send_without_block, we already generate a
known class guard, so we can detect when the receiver is a String
instance. Since gen_send_cfunc() is also used for gen_invokesuper(), and
gen_invokesuper() doesn't generate a known class guard, a new nullable
parameter for specialized codegen function is added.

Closes GH-245

Alan Wu 8edb29e5a0 Reconstruct interpreter state before calling rb_ivar_get() 
It could raise ractor exceptions. The included test didn't run properly
before this change.

Alan Wu d0a213b30d Remove a memory load in gen_send_iseq 
Instead of loading from meory for REG_SP, do a register rename instead.
It's cheaper.

Alan Wu 0a108601ef Add counters for version invalidation reasons 
I noticed that there were two st_table iterators that do exactly the
same thing so I merged them into one.

Alan Wu 78b5e95e41 Add a slowpath for opt_getinlinecache 
Before this change, when we encounter a constant cache that is specific
to a lexical scope, we unconditionally exit. This change falls back to
the interpreter's cache in this situation.

This should help constant expressions in `class << self`, which is popular
at Shopify due to the style guide.

This change relies on the cache being warm while compiling to detect the
need for checking the lexical scope for simplicity.

Alan Wu c46bda6f19 Fix excessive invalidation for opt_getinlinecache 
YJIT expects the VM to invalidate opt_getinlinecache when updating the
constant cache, and the invalidation used to happen even when YJIT can't
use the cached value.

Once the first invalidation happens, the block for opt_getinlinecache
becomes a stub. When the stub is hit, YJIT fails to compile the
instruction as the cache is not usable. The stub becomes a block that
exits for opt_getinlinecache which can be invalidated again. Some
workloads that bust the interpreter's constant cache can create an
invalidation loop with this behavior.

Check if the cache is usable become doing invalidation to fix this
problem.

In the test harness, evaluate the test script in a lambda instead of a
proc so `return` doesn't return out of the harness.

Alan Wu 6ef1609fab Correct margin for stack overflow test 
In vm_push_frame(), the stack overflow test is done against a
decremented cfp. YJIT wasn't accounting for that in its stack overflow
tests.

Alan Wu 1f6641681b No need to do ec->cfp = reg_cfp on exits 
It's already up to date. We set it when we do iseq calls and it's set
properly on entry. If it's not set properly exceptions wouldn't work.
