* [LegacyPassManager] Remove TargetMachine constructorsFrancis Visoiu Mistrih2017-05-181-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This provides a new way to access the TargetMachine through TargetPassConfig, as a dependency. The patterns replaced here are: * Passes handling a null TargetMachine call `getAnalysisIfAvailable<TargetPassConfig>`. * Passes not handling a null TargetMachine `addRequired<TargetPassConfig>` and call `getAnalysis<TargetPassConfig>`. * MachineFunctionPasses now use MF.getTarget(). * Remove all the TargetMachine constructors. * Remove INITIALIZE_TM_PASS. This fixes a crash when running `llc -start-before prologepilog`. PEI needs StackProtector, which gets constructed without a TargetMachine by the pass manager. The StackProtector pass doesn't handle the case where there is no TargetMachine, so it segfaults. Related to PR30324. Differential Revision: https://reviews.llvm.org/D33222 llvm-svn: 303360

* [mips] Do not allow -opt-bisect-limit to skip the PIC call optimization pass.Vasileios Kalintiris2016-10-271-3/+0
| | | | | | | | | | | | | | r282428 added the MipsOptimizePICCall as an opt-in pass that can be skipped when using the -opt-bisect-limit option. However, this pass is needed because it generates code that conforms to the o32 ABI specification by using the $t9 register for PIC calls with JALR instructions. This bug was exposed by the fact that skipFunction() also checks for the "optnone" attribute. This caused functions with that attribute to break the requirements of the o32 ABI. llvm-svn: 285305
