The write_val argument was not specified as an input on the asm instruction. The compiler thought it wasn't used, even though the asm instruction does use r0, which is how write_val is passed into the function. The compiler would optimise out the argument being passed into the function. Add write_val as an input operand to prevent it being optimised out.
