Constraints might permit a decrement and branch instruction that checks zeroness to be used when the user has specified to exit if negative. -* Smarter reload pass. - -The reload pass as currently written can reload values only into registers -that are reserved for reloading. This means that in order to use a -register for reloading it must spill everything out of that register. - -It would be straightforward, though complicated, for reload1.c to keep -track, during its scan, of which hard registers were available at each -point in the function, and use for reloading even registers that were -free only at the point they were needed. This would avoid much spilling -and make better code. - * Change the type of a variable. Sometimes a variable is declared as `int', it is assigned only once |
