But then the intrinsic would always be defined, which is contrary to what the ACLE spec demands - it would not give a compilation error at the callsite but give assembler errors (potentially in different functions after inlining). > What was the reason for using an inline asm rather than a builtin? > Feels a bit old school. :) Using a builtin should mean that the > RTL optimisers see the extent of the write. Given this intrinsic will be used very rarely, if ever, it does not make sense to provide anything more than the basic functionality. Cheers, Wilco
