2023-11-02YJIT: Always define method codegen table at boot (#8807)Takashi Kokubun
2023-10-24updating bindgenAaron Patterson
2023-10-20YJIT: Skip printing stats at exit if --yjit-disable (#8727)Takashi Kokubun
2023-10-19YJIT: remove unused `--yjit-greedy-versioning` command-line option (#8713)Maxime Chevalier-Boisvert
2023-10-19YJIT: Return Option from asm.compile() for has_dropped_bytes()Alan Wu
So that we get a reminder to check CodeBlock::has_dropped_bytes(). Internally, asm.compile() already checks it, and this patch just propagates it out to the caller with a `#[must_use]`. Code GC logic moved out one level in entry_stub_hit(), so the body can freely use `?`
2023-10-19YJIT: Add RubyVM::YJIT.enable (#8705)Takashi Kokubun
2023-10-19YJIT: Enable the dead_code lint and delete some dead codeAlan Wu
2023-10-18YJIT: Add a live ISeq counter Alan Wu
It's an estimator for application size and could be used as a compilation heuristic later. Co-authored-by: Maxime Chevalier-Boisvert <maxime.chevalierboisvert@shopify.com> Co-authored-by: Takashi Kokubun <takashikkbn@gmail.com>

2023-10-17YJIT: Remove call to compile() on empty AssemblerAlan Wu
2023-10-17YJIT: Add a few missing counters for send fallback (#8681)Takashi Kokubun
2023-10-17YJIT: Lookup IDs on boot instead of binding to themAlan Wu
Previously, the version-controlled `cruby_bindings.inc.rs` file contained the build-time artifact `id.h`, which nobu mentioned hinders the goal of having fewer magic numbers in the repository. Lookup the IDs YJIT needs on boot. It costs cycles, but it's fine since YJIT only uses a handful of IDs at the moment. No perceptible degradation to boot time found in my testing.
2023-10-14YJIT: Count cold_iseq_entry by default (#8654)Takashi Kokubun
2023-10-13YJIT: Fallback opt_getconstant_path for const_missing (#8623)Takashi Kokubun
* YJIT: Fallback opt_getconstant_path for const_missing * Fix a comment [ci skip] * Remove a wrapper function
2023-10-13YJIT: Fix argument clobbering in some block_arg+rest_param calls (#8647)Alan Wu
Previously, for block argument callsites with some specific argument count and callee local variable count combinations, YJIT ended up writing over arguments that are supposed to be collected into a rest parameter array unmodified. Detect when clobbering would happen and avoid it. Also, place the block handler after the stack overflow check, since it writes to new stack space.

2023-10-12YJIT: port call threshold logic from Rust to C for performance (#8628)Maxime Chevalier-Boisvert
* Port call threshold logic from Rust to C for performance * Prefix global/field names with yjit_ * Fix linker error * Fix preprocessor condition for rb_yjit_threshold_hit * Fix third linker issue * Exclude yjit_calls_at_interv from RJIT bindgen --------- Co-authored-by: Takashi Kokubun <takashikkbn@gmail.com>
2023-10-11shape.h: Make attr_index_t uint8_tJean Boussier
Given `SHAPE_MAX_NUM_IVS 80`, we transition to TOO_COMPLEX way before we could overflow a 8bit counter. This reduce the size of `rb_shape_t` from 32B to 24B. If we decide to raise `SHAPE_MAX_NUM_IVS` we can always increase that type again.
2023-10-10YJIT: Allow --yjit-trace-exits on release builds (#8619)Takashi Kokubun
2023-10-10Refactor rb_shape_transition_shape_capa to not accept capacityJean Boussier
This way the groth factor is encapsulated, which allows rb_shape_transition_shape_capa to be smarter about ideal sizes.
2023-10-05YJIT: shink local types from 8 to 4 bytes (#8597)Maxime Chevalier-Boisvert
* Shink local types from 8 to 4 bytes, context from 21 to 17 bytes Use repr(packed) * Add comment about Type being limited to 4 bits
2023-10-05YJIT: Run bindgenAlan Wu
2023-10-05YJIT: Remove duplicate cfp->iseq accessorAlan Wu
2023-10-05YJIT: Avoid writing return value to memory in `leave`Alan Wu
Previously, at the end of `leave` we did `*caller_cfp->sp = return_value`, like the interpreter. With future changes that leaves the SP field uninitialized for C frames, this will become problematic. For cases like returning from `rb_funcall()`, the return value was written above the stack and never read anyway (callers use the copy in the return register). Leave the return value in a register at the end of `leave` and have the code at `cfp->jit_return` decide what to do with it. This avoids the unnecessary memory write mentioned above. For JIT-to-JIT returns, it goes through `asm.stack_push()` and benefits from register allocation for stack temporaries. Mostly flat on benchmarks, with maybe some marginal speed improvements.

Since the compile-time iseq used in the guard was not marked and updated during compaction, a runtime value reusing the address could falsely pass the guard. Co-authored-by: Takashi Kokubun <takashikkbn@gmail.com>

/yjit/src/backend/x86_64/mod.rs Is also UTF-8 and it doesn't have the marker. The standard recommends against it, so remove it.
2023-09-14YJIT: Plug native stack overflowAlan Wu
Previously, TestStack#test_machine_stack_size failed pretty consistently on ARM64 macOS, with Rust code and part of the interpreter used for per-instruction fallback (rb_vm_invokeblock() and friends) touching the stack guard page and crashing with SEGV. I've also seen the same test fail on x64 Linux, though with a different symptom. Notes: Merged: https://github.com/ruby/ruby/pull/8443 Merged-By: XrXr

2023-09-12Make Kernel#lambda raise when given non-literal blockAlan Wu
Previously, Kernel#lambda returned a non-lambda proc when given a non-literal block and issued a warning under the `:deprecated` category. With this change, Kernel#lambda will always return a lambda proc, if it returns without raising. Due to interactions with block passing optimizations, we previously had two separate code paths for detecting whether Kernel#lambda got a literal block. This change allows us to remove one path, the hack done with rb_control_frame_t::block_code introduced in 85a337f for supporting situations where Kernel#lambda returned a non-lambda proc.
