2023-02-20YJIT: Fix assertion for partially mapped last pages (#7337)Takashi Kokubun
Follows up [Bug #19400] Notes: Merged-By: k0kubun <takashikkbn@gmail.com>
2023-02-17YJIT: Consolidate jit methods in JITState impl (#7336)Jimmy Miller
These jit_* methods don't jit code, but instead check things on the JITState. We had other methods that did the same thing that were just added on the impl JITState. For consistency I added these methods there. Notes: Merged-By: maximecb <maximecb@ruby-lang.org>

2023-02-16YJIT: jit_prepare_routine_call() for String#+@ missingAlan Wu
We saw SEGVs due to this when running with StackProf, which needs a correct PC for RUBY_INTERNAL_EVENT_NEWOBJ, the same event used for ObjectSpace allocation tracing. [Bug #19444] Notes: Merged: https://github.com/ruby/ruby/pull/7328

2023-02-16Move `attached_object` into `rb_classext_struct`Jean Boussier
Given that signleton classes don't have an allocator, we can re-use these bytes to store the attached object in `rb_classext_struct` without making it larger. Notes: Merged: https://github.com/ruby/ruby/pull/7309
2023-02-15YJIT: `Kernel#{is_a?,instance_of?}` fast paths (GH-7297)Jimmy Miller

2023-02-15Encapsulate RCLASS_ATTACHED_OBJECTJean Boussier
Right now the attached object is stored as an instance variable and all the call sites that either get or set it have to know how it's stored. It's preferable to hide this implementation detail behind accessors so that it is easier to change how it's stored. Notes: Merged: https://github.com/ruby/ruby/pull/7308

2023-02-10use correct svar even if env is escapedKoichi Sasada
This patch is follo-up of 0a82bfe. Without this patch, if env is escaped (Proc'ed), strange svar can be touched. This patch tracks escaped env and use it. Notes: Merged: https://github.com/ruby/ruby/pull/7282

2023-02-09YJIT: Support invokesuper in a block (#7264)Maple Ong
Support invokesuper in a block on YJIT invokesuper previously side exited when it is in a block. To make sure we're compiling the correct method in super, we now use the local environment pointer (LEP) to get the method, which will work in a block.

2023-02-09YJIT: Add counter for megamorphic send (#7274)Takashi Kokubun
Notes: Merged-By: maximecb <maximecb@ruby-lang.org>
2023-02-09YJIT: Use the system page size when the code page size is too small (#7267)Alan Wu
Previously on ARM64 Linux systems that use 64 KiB pages (`CONFIG_ARM64_64K_PAGES=y`), YJIT was panicking on boot due to a failed assertion. The assertion was making sure that code GC can free the last code page that YJIT manages without freeing unrelated memory. YJIT prefers picking 16 KiB as the granularity at which to free code memory, but when the system can only free at 64 KiB granularity, that is not possible. The fix is to use the system page size as the code page size when the system page size is 64 KiB. Continue to use 16 KiB as the code page size on common systems that use 16/4 KiB pages. Add asserts to code_gc() and free_page() about code GC's assumptions. Fixes [Bug #19400] Notes: Merged-By: maximecb <maximecb@ruby-lang.org>

YJIT: Skip gen_check_ints on ISEQ send On the interpreter, vm_push_frame doesn't check interrupts. Only vm_pop_frame does. Notes: Merged-By: maximecb <maximecb@ruby-lang.org>
2023-02-03YJIT: Make Block::start_addr non-optionalAlan Wu
We set the block address as soon as we make the block, so there is no point in making it `Option<CodePtr>`. No memory saving, unfortunately, as `mem::size_of::<Block>() = 176` before and after this change. Still a simplification for the logic, though. Notes: Merged: https://github.com/ruby/ruby/pull/7243

2023-02-02YJIT: Crash with rb_bug() when panickingAlan Wu

2023-02-02YJIT: ARM64: Fix long jumps to labelsAlan Wu
Previously, with Code GC, YJIT panicked while trying to emit a B.cond instruction with an offset that is not encodable in 19 bits. This only happens when the code in an assembler instance straddles two pages. To fix this, when we detect that a jump to a label can land on a different page, we switch to a fresh new page and regenerate all the code in the assembler there. We still assume that no one assembler has so much code that it wouldn't fit inside a fresh new page.

2023-02-02YJIT: other_cb is None in testsAlan Wu
Since the other cb is in CodegenGlobals, and we want Rust tests to be self-contained. Notes: Merged: https://github.com/ruby/ruby/pull/7227
2023-02-02YJIT: Move CodegenGlobals::freed_pages into an RcAlan Wu
This allows for supplying a freed_pages vec in Rust tests. We need it so we can test scenarios that occur after code GC. Notes: Merged: https://github.com/ruby/ruby/pull/7227
2023-02-01use correct svar (#7225)Koichi Sasada
* use correct svar Without this patch, svar location is used "nearest Ruby frame". It is almost correct but it doesn't correct when the `each` method is written in Ruby. ```ruby class C include Enumerable def each %w(bar baz).each{|e| yield e} end end C.new.grep(/(b.)/){|e| p [$1, e]} ``` This patch fix this issue by traversing ifunc's cfp. Note that if cfp doesn't specify this Thread's cfp stack, reserved svar location (`ec->root_svar`) is used. * make yjit-bindgen --------- Co-authored-by: Takashi Kokubun <takashikkbn@gmail.com> Notes: Merged-By: k0kubun <takashikkbn@gmail.com>

2023-01-19YJIT: Remove duplicated information in BranchTarget (#7151)Takashi Kokubun
Note: On the new code of yjit/src/core.rs:2178, we no longer leave the state `.block=None` but `.address=Some...`, which might be important. We assume it's actually not needed and take a risk here to minimize heap allocations, but in case it turns out to be necessary, we could signal/resurrect that state by introducing a new BranchTarget (or BranchShape) variant dedicated to it.
