Using traps for assertions like Linux does gives a few advantages: - The asm code leading to the failure condition is nicer. - The interrupt gives a clean snapshot of machine state to dump. The difficulty with using traps for this in OPAL is that the runtime component will not deal well with the OS taking the 0x700 interrupt caused by a trap in OPAL. The long term goal is to improve the ability of the OS to inspect and debug OPAL at runtime. For now though, the traps are patched out before passing control to the OS, and the assert falls through to in-line failure handling.
