| const char * default_invalid_within_doloop | ( | const rtx_insn * | insn | ) |
NULL if INSN insn is valid within a low-overhead loop, otherwise returns an error message. This function checks whether a given INSN is valid within a low-overhead loop. If INSN is invalid it returns the reason for that, otherwise it returns NULL. A called function may clobber any special registers required for low-overhead looping. Additionally, some targets (eg, PPC) use the count register for branch on table instructions. We reject the doloop pattern in these cases.

The migration of target macros to target hooks works as follows: 1. Create a target hook that uses the existing target macros to implement the same functionality. 2. Convert all the MI files to use the hook instead of the macro. 3. Repeat for a majority of the remaining target macros. This will take some time. 4. Tell target maintainers to start migrating. 5. Eventually convert the backends to override the hook instead of defining the macros. This will take some time too. 6. TBD when, poison the macros. Unmigrated targets will break at this point. Note that we expect steps 1-3 to be done by the people that understand what the MI does with each macro, and step 5 to be done by the target maintainers for their respective targets. Note that steps 1 and 2 don't have to be done together, but no target can override the new hook until step 2 is complete for it. Once the macros are poisoned, we will revert to the old migration rules - migrate the macro, callers, and targets all at once. This comment can thus be removed at that point.
