Re: [PATCH] Improved trailing bit counting operation

BTW,
what about making scan-assembler a little bit smarter and make it ignore directives such as .file, so it focus on pure assembly only?

I know, developers should be smarter too :) But this could be some useful improvement.

Sorry guys, I'm not sure I understand your point.

ctz is not an ARM instruction, that's why __builtin_ctz is
implemented using other existing instructions (rbit, clz).

Is that what you are referring to?

Then what's this for?

+/* { dg-final { scan-assembler "ctz" } } */
