If you say e.g. void f(void) { asm(".macro something\n\t.endm"); } there is nothing that prevents the compiler from emitting this more than once. Expecting things to be emitted in whatever order is a bad idea, too. The thing with .purgem can work. Inelegant, sure, but it can work :-) Just make sure you do the macro define, the code that uses it, and the undefine, all in the same inline asm statement.
