* ZJIT: Add code_region_bytes stat * Share more logic among --zjit and --zjit-stats
The `shape_id` now includes 3 bits for the `heap_id`. It is always non-zero for `T_OBJECT` and always zero for all other types. Hence all these allocator checks are no longer necessary.
While accessing the ivars of other types is too complicated to realistically generate the ASM for it, we can at least provide the ivar index as to not have to lookup the shape tree every time. ``` compare-ruby: ruby 3.5.0dev (2025-08-27T14:58:58Z merge-vm-setivar-d.. 5b749d8e53) +YJIT +PRISM [arm64-darwin24] built-ruby: ruby 3.5.0dev (2025-08-28T17:58:32Z yjit-get-exivar efaa8c9) +YJIT +PRISM [arm64-darwin24] | |compare-ruby|built-ruby| |:--------------------------|-----------:|---------:| |vm_ivar_get_on_obj | 930.458| 936.865| | | -| 1.01x| |vm_ivar_get_on_class | 134.471| 431.622| | | -| 3.21x| |vm_ivar_get_on_generic | 146.679| 284.408| | | -| 1.94x| ``` Co-Authored-By: Aaron Patterson <tenderlove@ruby-lang.org>
The only exception it could raise is if we're in multi ractor mode.
Using `assume_single_ractor_mode` we can skip all ractor safety checks if we're in single ractor mode. ``` compare-ruby: ruby 3.5.0dev (2025-08-27T14:58:58Z merge-vm-setivar-d.. 5b749d8e53) +YJIT +PRISM [arm64-darwin24] built-ruby: ruby 3.5.0dev (2025-08-28T21:23:38Z yjit-get-exivar 3cc21b76d4) +YJIT +PRISM [arm64-darwin24] | |compare-ruby|built-ruby| |:--------------------------|-----------:|---------:| |vm_ivar_get_on_obj | 975.981| 975.772| | | 1.00x| -| |vm_ivar_get_on_class | 136.214| 470.912| | | -| 3.46x| |vm_ivar_get_on_generic | 148.315| 299.122| | | -| 2.02x| ```
