class TrampolinePool

Declaration

class TrampolinePool { /* full declaration omitted */ };

Description

Base class for pools of compiler re-entry trampolines. These trampolines are callable addresses that save all register state before calling a supplied function to return the trampoline landing address, then restore all state before jumping to that address. They are used by various ORC APIs to support lazy compilation
