H A D | excp_helper.c | 154c69f2 Fri Feb 15 10:16:39 CST 2019 Benjamin Herrenschmidt <benh@kernel.crashing.org> target/ppc: Fix nip on power management instructions Those instructions currently raise an exception from within the helper. This tends to result in a bogus nip value in the env context (typically the beginning of the TB). Such a helper needs a gen_update_nip() first. This fixes it with a different approach which is to throw the exception from translate.c instead of the helper using gen_exception_nip() which does the right thing. Exception EXCP_HLT is also used instead of POWERPC_EXCP_STOP to effectively exit from the CPU execution loop.
