Splits a module into multiple linkable partitions.
Declared in <llvm/Transforms/Utils/SplitModule.h>
void
SplitModule(
Module& M,
unsigned int N,
function_ref<void(std::unique_ptr<Module>)> ModuleCallback,
bool PreserveLocals = false,
bool RoundRobin = false);ModuleCallback is called N times, passing each individual partition as the MPart argument.
FIXME: This function does not deal with the somewhat subtle symbol visibility issues around module splitting, including (but not limited to):
Internal symbols should not collide with symbols defined outside the module.
Internal symbols defined in module-level inline asm should be visible to each partition.
| Name | Description |
|---|---|
| M | Module to split. |
| N | Number of linkable partitions to produce. |
| ModuleCallback | Callback invoked once per partition with that partition. |
| PreserveLocals | If true, split without externalizing locals. |
| RoundRobin | If true, use round-robin distribution of functions to modules instead of the default name-hash-based one. |
