How to 32- or 64-byte align ARM assembly code for use with Xcode/gcc?

Question

I have some assembly code that I need to align to a 32 or preferably 64-byte boundary.

I have two scenarios: Aligning the beginning of a function, or having the assembler automatically insert no-ops to align the beginning of a loop.

Are these possible?

Thanks very much.

Answer 1

just use

.align 64

and the assembler should insert nops to the next 64-byte boundary, if not already aligned.
