Entry point for module splitting.
Targets can implement custom module splitting logic, mainly used by LTO for –lto-partitions.
true
if the module was split, false
otherwise. When false
is returned, it is assumed that ModuleCallback
has never been called and M
has not been modified. Reimplemented in llvm::AMDGPUTargetMachine.
