That is essential, an inlined method can be separated in non-contiguous regions for performance during CFG alignment. IMHO, we should register several code blocks for the same inlined method (if the method's code was split into parts) through the compiled_method_load(...) interface. This can be done completely on the JIT side. What do you, guys, think? -- Egor Pasko
