targhooks - provide an alternative hook for targets that never execute speculatively
This hook adds an alternative implementation for the target hook
TARGET_HAVE_SPECULATION_SAFE_VALUE; it can be used by targets that have no
CPU implementations that execute code speculatively. All that is needed for
such targets now is to add:
#undef TARGET_HAVE_SPECULATION_SAFE_VALUE
#define TARGET_HAVE_SPECULATION_SAFE_VALUE speculation_safe_value_not_needed.
to where you have your other target hooks and you're done.
gcc:
* targhooks.h (speculation_safe_value_not_needed): New prototype.
* targhooks.c (speculation_safe_value_not_needed): New function.
* target.def (have_speculation_safe_value): Update documentation.
* doc/tm.texi: Regenerated.
