Make that:
/*
* If @feature is set, patch @newinstr_yes, else @newinstr_no
*/
#define ALTERNATIVE_TERNARY(oldinstr, feature, newinstr_yes, newinstr_no) \
ALTERNATIVE_2(oldinstr, newinstr_no, X86_FEATURE_ALWAYS, newinstr_yes,
feature)
and in alternative-asm.h too pls.
Regardless, this looks nice! :)
Thx.
