| 2021-10-20 | YJIT: Fancier opt_getinlinecache | Alan Wu | |
| Make sure `opt_getinlinecache` is in a block all on its own, and invalidate it from the interpreter when `opt_setinlinecache`. It will recompile with a filled cache the second time around. This lets YJIT runs well when the IC for constant is cold. | |||
| 2021-10-20 | Fix stack-use-after-scope in gen_direct_jump() | Alan Wu | |
| ASAN can catch these type of things for us, but the scraper can't handle ASAN :/. To be more resilient to refactoring, extend the lifetime of `generic_ctx` in branch_stub_hit() too. | |||

| 2021-10-20 | Collect statistics about binding allocations / local variable set | Aaron Patterson | |
| This commit collects statistics about how many binding objects are allocated as well as the number of local variables set on bindings. Statistics are output along with other YJIT stats. Here is an example of the output: ``` ***YJIT: Printing runtime counters from yjit.rb*** Number of Bindings Allocated: 195 Number of locals modified through binding: 0 opt_send_without_block exit reasons: ivar_get_method 7515891 (40.4%) se_cc_klass_differ 3081330 (16.6%) iseq_argc_mismatch 1564578 ( 8.4%) se_receiver_not_heap 1557663 ( 8.4%) ic_empty 1407064 ( 7.6%) optimized_method 995823 ( 5.4%) iseq_not_simple 819413 ( 4.4%) alias_method 706972 ( 3.8%) bmethod 685253 ( 3.7%) callsite_not_simple 225983 ( 1.2%) kw_splat 25999 ( 0.1%) ivar_set_method 902 ( 0.0%) cfunc_toomany_args 394 ( 0.0%) refined_method 42 ( 0.0%) cfunc_ruby_array_varg 29 ( 0.0%) invalid_cme 4 ( 0.0%) leave exit reasons: se_finish_frame 4067107 (100.0%) se_interrupt 24 ( 0.0%) getinstancevariable exit reasons: undef 121177 (100.0%) idx_out_of_range 5 ( 0.0%) opt_aref exit reasons: (all relevant counters are zero) compiled_iseq_count: 3944 main_block_code_size: 1.1 MiB side_block_code_size: 0.6 MiB vm_insns_count: 1137268516 yjit_exec_insns_count: 414015644 ratio_in_yjit: 26.7% avg_len_in_yjit: 7.5 total_exit_count: 55491789 most frequent exit op: opt_send_without_block: 18587628 (33.5%) opt_getinlinecache: 11075822 (20.0%) send: 4949300 (8.9%) leave: 4067131 (7.3%) defined: 3975196 (7.2%) setinstancevariable: 3567315 (6.4%) invokesuper: 2982163 (5.4%) getblockparamproxy: 2168852 (3.9%) opt_nil_p: 2104524 (3.8%) opt_aref: 2013858 (3.6%) ``` Running RailsBench allocates 195 binding objects but doesn't set any local variables. | |||

| 2021-10-20 | YJIT: adjust branch shape properly when target already exists | Alan Wu | |
| The old code decides branch->shape based on the write position of the native code block, which is unsound in case the block already exists and no new code is written to the write position. Make this decision with the start address of the target block instead. Also handle when the branch becomes smaller after patching. | |||

| 2021-10-20 | Fix improper use of st_foreach_with_replace | Alan Wu | |
| Replacing the key was only okay if the new key hashes to the same thing as the old key. That doesn't hold for YJIT's table when the keys move. | |||
| 2021-10-20 | Fix GCC warnings | Alan Wu | |

| 2021-10-20 | Factor out protected callee guard, check for private callees | Alan Wu | |
| We didn't need the private check before because we were lifting from the interpreter's cache, and the interpreter only caches when visibility checks go through. | |||
