Detect opportunities to hoist function calls that are invariant outside of loop bodies for efficiency.
- C/C++/ObjC: Yes
- Java: Yes
This checker detects opportunities to hoist function calls that are invariant to outside of loop bodies. The hoisting analysis relies on purity analysis to determine whather a function is pure or not.
It has an additional mode that reports loop-invariant functions that are expensive (i.e. at least linear). This is enabled by the flag
