Created page with "An interrupt handler should always ensure that the stack pointer and some control registers are the same at the entry and exit of the function. This message tells you that thi..."

New page

An interrupt handler should always ensure that the stack pointer and some control registers are the same at the entry and exit of the function. This message tells you that this didn't happen: the stack pointer or control register was different at the interrupt return than when the interrupt handler started executing.

=== Debugging ===
See [[Msg/ClobberedSP]], which is a similar error for functions instead of interrupts.

=== Implementation ===
The simulator identifies interrupts and return-from-interrupt instructions executed at runtime. It records the values of registers at interrupts, and verifies that they haven't changed when executing the matching interrupt return This warning is generated at the interrupt return instruction.
