Is there a way to repeat the same series of bytes many time in Apple's assembler?
Example use-case: if I want to make an iPhone app with a gigabyte of NOP instructions in some function.
You can use .fill
.fill 69, 4, 0xfeadface
Generates 69 longs of value 0xfeadface
ten_ones: .space 10, 1
when dealing with bytes only.
I couldn't find the equivalent of NASM
TIMES that would let you repeat even instructions.
You can try to achieve that with recursive macros; I don't have access to Apple assembler, thus I can only sketch a possible macro.
Beware of syntax issues, expressiveness and arguments forwarding when dealing with (supposed) limited languages like that used for macros.
.macro TIMES .if $0 > 0 $1 var $0-1 $1 .endif .endmacro TIMES 100, mov
