Hello,

the SPU processor is not affected by speculation, so this macro can
safely be defined as speculation_safe_value_not_needed.

Committed to mainline.

Bye,
Ulrich


gcc/ChangeLog:

	PR target/86807
	* config/spu/spu.c (TARGET_HAVE_SPECULATION_SAFE_VALUE):
	Define to speculation_safe_value_not_needed.

Patch
