WebTo prevent this from happening, if any input operand uses the ‘ f ’ constraint, all output register constraints must use the ‘ & ’ early-clobber modifier. The example above is correctly written as: asm ("foo" : "=&t" (a) : "f" (b)); Some operands need to be in particular places on the stack.

WebJan 14, 2024 · Notice that the compiler enumerates the operand starting with %0, and that you don't have to add a register to the clobbered register list if it's used to store an output operand. GCC is smart enough to figure out what to do all by itself. Starting with GCC 3.1, you can use more readable labels instead of the error-prone enumeration: the holzer files tv show cast
