Move the _main argument to the input list rather than the output one on the asm block and change the spec to "r". The ASM block does not return, so it does not make sense for it to expect any output.

Add "memory" to the clobber list" From GCC 14 the compiler optimizes away memory accesses that do not impact the asm block. Adding the memory to the clobber list lets the compiler know that the memory state is to be preserved.
