2025-12-09ZJIT: Add codegen for FixnumDiv (#15452)Abrar Habib
Fixes https://github.com/Shopify/ruby/issues/902 This pull request adds code generation for dividing fixnums. Testing confirms the normal case, flooring, and side-exiting on division by zero.

2025-12-03ZJIT: Optimize setivar with shape transition (#15375)Max Bernstein
Since we do a decent job of pre-sizing objects, don't handle the case where we would need to re-size an object. Also don't handle too-complex shapes. lobsters stats before: ``` Top-20 calls to C functions from JIT code (79.4% of total 90,051,140): rb_vm_opt_send_without_block: 19,762,433 (21.9%) rb_vm_setinstancevariable: 7,698,314 ( 8.5%) rb_hash_aref: 6,767,461 ( 7.5%) rb_vm_env_write: 5,373,080 ( 6.0%) rb_vm_send: 5,049,229 ( 5.6%) rb_vm_getinstancevariable: 4,535,259 ( 5.0%) rb_obj_is_kind_of: 3,746,306 ( 4.2%) rb_ivar_get_at_no_ractor_check: 3,745,237 ( 4.2%) rb_vm_invokesuper: 3,037,467 ( 3.4%) rb_ary_entry: 2,351,983 ( 2.6%) rb_vm_opt_getconstant_path: 1,344,740 ( 1.5%) rb_vm_invokeblock: 1,184,474 ( 1.3%) Hash#[]=: 1,064,288 ( 1.2%) rb_gc_writebarrier: 1,006,972 ( 1.1%) rb_ec_ary_new_from_values: 902,687 ( 1.0%) fetch: 898,667 ( 1.0%) rb_str_buf_append: 833,787 ( 0.9%) rb_class_allocate_instance: 822,024 ( 0.9%) Hash#fetch: 699,580 ( 0.8%) _bi20: 682,068 ( 0.8%) Top-4 setivar fallback reasons (100.0% of total 7,732,326): shape_transition: 6,032,109 (78.0%) not_monomorphic: 1,469,300 (19.0%) not_t_object: 172,636 ( 2.2%) too_complex: 58,281 ( 0.8%) ``` lobsters stats after: ``` Top-20 calls to C functions from JIT code (79.0% of total 88,322,656): rb_vm_opt_send_without_block: 19,777,880 (22.4%) rb_hash_aref: 6,771,589 ( 7.7%) rb_vm_env_write: 5,372,789 ( 6.1%) rb_gc_writebarrier: 5,195,527 ( 5.9%) rb_vm_send: 5,049,145 ( 5.7%) rb_vm_getinstancevariable: 4,538,485 ( 5.1%) rb_obj_is_kind_of: 3,746,241 ( 4.2%) rb_ivar_get_at_no_ractor_check: 3,745,172 ( 4.2%) rb_vm_invokesuper: 3,037,157 ( 3.4%) rb_ary_entry: 2,351,968 ( 2.7%) rb_vm_setinstancevariable: 1,703,337 ( 1.9%) rb_vm_opt_getconstant_path: 1,344,730 ( 1.5%) rb_vm_invokeblock: 1,184,290 ( 1.3%) Hash#[]=: 1,061,868 ( 1.2%) rb_ec_ary_new_from_values: 902,666 ( 1.0%) fetch: 898,666 ( 1.0%) rb_str_buf_append: 833,784 ( 0.9%) rb_class_allocate_instance: 821,778 ( 0.9%) Hash#fetch: 755,913 ( 0.9%) Top-4 setivar fallback reasons (100.0% of total 1,703,337): not_monomorphic: 1,472,405 (86.4%) not_t_object: 172,629 (10.1%) too_complex: 58,281 ( 3.4%) new_shape_needs_extension: 22 ( 0.0%) ``` I also noticed that primitive printing in HIR was broken so I fixed that.

2025-08-29ZJIT: Specialize monomorphic GetIvar (#14388)Max Bernstein
Specialize monomorphic `GetIvar` into: * `GuardType(HeapObject)` * `GuardShape` * `LoadIvarEmbedded` or `LoadIvarExtended` This requires profiling self for `getinstancevariable` (it's not on the operand stack). This also optimizes `GetIvar`s that happen as a result of inlining `attr_reader` and `attr_accessor`. Also move some (newly) shared JIT helpers into jit.c.

2025-06-28ZJIT: Codegen for `defined?(yield)`Alan Wu
Lots of stdlib methods such as Integer#times and Kernel#then use this, so at least this will make writing tests slightly easier.
2025-06-23ZJIT: Optimize frozen array aref (#13666)Max Bernstein
If we have a frozen array `[..., a, ...]` and a compile-time fixnum index `i`, we can do the array load at compile-time.
2025-05-02YJIT: ZJIT: Share identical glue functionsAlan Wu
Working towards having YJIT and ZJIT in the same build, we need to deduplicate some glue code that would otherwise cause name collision. Add jit.c for this and build it for YJIT and ZJIT builds. Update bindgen to look at jit.c; some shuffling of functions in the output, but the set of functions shouldn't have changed. Notes: Merged: https://github.com/ruby/ruby/pull/13229
