charset="utf-8" From: Artyom Kunakovsky The point of CPU_CFLAGS is really just to select the appropriate multilib, for example for library linking tests, and -mcx16 is not needed for that purpose. Furthermore, if -mcx16 is part of QEMU's choice of a basic x86_64 instruction set, it should be applied to cross-compiled x86_64 code too; it is plausible that tests/tcg would want to cover cmpxchg16b as well, for example. In the end this makes just as much sense as a per sub-build tweak, so move the flag to meson.build and cross_cc_cflags_x86_64. This leaves out contrib/plugins, which would fail when attempting to use __sync_val_compare_and_swap_16 (note it does not do yet); while minor, this *is* a disadvantage of this change. But building contrib/plugins with a Makefile instead of meson.build is something self-inflicted just for the sake of showing that it can be done, and if this kind of papercut started becoming a problem we could make the directory part of the meson build. Until then, we can live with the limitation.

charset="utf-8" gen_helper_rsm cannot generate an exception, and reloads the flags. So there's no need to spill cc_op and update cpu_eip, but on the other hand cc_op must be reset to CC_OP_EFLAGS before returning. It all works by chance, because by spilling cc_op before the call to the helper, it becomes non-dirty and gen_eob will not overwrite the CC_OP_EFLAGS value that is placed there by the helper. But let's clean it up.
