We certainly don't want to shrink wrap functions if we've emitted a MovePCtoLR8 as that has to go into the entry, so the prologue definitely has to go into the entry block.

◆ setMustSaveLR()

void llvm::PPCFunctionInfo::setMustSaveLR ( bool U) inline

MustSaveLR - This is set when the prolog/epilog inserter does its initial scan of the function.

It is true if the LR/LR8 register is ever explicitly defined/clobbered in the machine function (e.g. by calls and movpctolr, which is used in PIC generation), or if the LR stack slot is explicitly referenced by builtin_return_address.
