* ujit: implement opt_getinlinecache Aggressively bet that writes to constants don't happen and invalidate all opt_getinlinecache blocks on any and all constant writes. Use alignment padding on block_t to track this assumption. No change to sizeof(block_t). * Fix compile warnings when not RUBY_DEBUG * Fix reversed condition * Switch to st_table to keep track of assumptions Co-authored-by: Aaron Patterson <aaron.patterson@gmail.com> Co-authored-by: Maxime Chevalier-Boisvert <maximechevalierb@gmail.com>
