* [SPARC] Switch to the Machine Scheduler.James Y Knight2015-09-101-1/+2
| | | | | | | | | | | | | The (mostly-deprecated) SelectionDAG-based ILPListDAGScheduler scheduler was making poor scheduling decisions, causing high register pressure and extraneous register spills. Switching to the newer machine scheduler generates better code -- even without there being a machine model defined for SPARC yet. (Actually committing the test changes too, this time, unlike r247315) llvm-svn: 247343

* Remove getDataLayout() from TargetSelectionDAGInfo (had no users)Mehdi Amini2015-07-091-3/+3
| | | | | | | | | | | | | | | | | | Summary: Remove empty subclass in the process. This change is part of a series of commits dedicated to have a single DataLayout during compilation by using always the one owned by the module.

* Move DataLayout back to the TargetMachine from TargetSubtargetInfoEric Christopher2015-01-261-2/+0
| | | | | | | | | | | | | | | | | | | derived classes. Since global data alignment, layout, and mangling is often based on the DataLayout, move it to the TargetMachine. This ensures that global data is going to be layed out and mangled consistently if the subtarget changes on a per function basis. Prior to this all targets(*) have had subtarget dependent code moved out and onto the TargetMachine. *One target hasn't been migrated as part of this change: R600. The R600 port has, as a subtarget feature, the size of pointers and this affects global data layout. I've currently hacked in a FIXME to enable progress, but the port needs to be updated to either pass the 64-bitness to the TargetMachine, or fix the DataLayout to avoid subtarget dependent features. llvm-svn: 227113
* Reinstate "Nuke the old JIT."Eric Christopher2014-09-021-3/+0
| | | | | | | | Approved by Jim Grosbach, Lang Hames, Rafael Espindola. This reinstates commits r215111, 215115, 215116, 215117, 215136. llvm-svn: 216982
* Canonicalize header guards into a common format.Benjamin Kramer2014-08-131-2/+2
| | | | | | | | | | Add header guards to files that were missing guards. Remove #endif comments as they don't seem common in LLVM (we can easily add them back if we decide they're useful) Changes made by clang-tidy with minor tweaks. llvm-svn: 215558
