* Use the new script to sort the includes of every file under lib.Chandler Carruth2012-12-031-3/+3
| | | | | | | | | | | | | | | | | Sooooo many of these had incorrect or strange main module includes. I have manually inspected all of these, and fixed the main module include to be the nearest plausible thing I could find. If you own or care about any of these source files, I encourage you to take some time and check that these edits were sensible. I can't have broken anything (I strictly added headers, and reordered them, never removed), but they may not be the headers you'd really like to identify as containing the API being implemented. Many forward declarations and missing includes were added to a header files to allow them to parse cleanly when included first. The main module rule does in fact have its merits. =] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169131 91177308-0d34-0410-b5e6-96231b3b80d8
* Tidy up a few more uses of MF.getFunction()->getName().David Blaikie2012-08-221-2/+1
| | | | | | | | Based on CR feedback from r162301 and Craig Topper's refactoring in r162347 here are a few other places that could use the same API (& in one instance drop a Function.h dependency). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162367 91177308-0d34-0410-b5e6-96231b3b80d8
* Add a getName function to MachineFunction. Use it in places that previously ↵Craig Topper2012-08-221-2/+1

| | | | | | Patch by Tyler Nowicki! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160888 91177308-0d34-0410-b5e6-96231b3b80d8
* Codegen pass definition cleanup. No functionality.Andrew Trick2012-02-081-7/+3
| | | | | | | | | | | | | Moving toward a uniform style of pass definition to allow easier target configuration. Globally declare Pass ID. Globally declare pass initializer. Use INITIALIZE_PASS consistently. Add a call to the initializer from CodeGen.cpp. Remove redundant "createPass" functions and "getPassName" methods. While cleaning up declarations, cleaned up comments (sorry for large diff). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@150100 91177308-0d34-0410-b5e6-96231b3b80d8
* Add bundle aware API for querying instruction properties and switch the codeEvan Cheng2011-12-071-1/+1
| | | | | | | | | | | | | | | generator to it. For non-bundle instructions, these behave exactly the same as the MC layer API. For properties like mayLoad / mayStore, look into the bundle and if any of the bundled instructions has the property it would return true. For properties like isPredicable, only return true if *all* of the bundled instructions have the property. For properties like canFoldAsLoad, isCompare, conservatively return false for bundles. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@146026 91177308-0d34-0410-b5e6-96231b3b80d8
* Give targets a chance to expand even standard pseudos.Jakob Stoklund Olesen2011-10-101-4/+12
| | | | | | | | | | | Allow targets to expand COPY and other standard pseudo-instructions before they are expanded with copyPhysReg(). This allows the target to examine the COPY instruction for extra operands indicating it can be widened to a preferable super-register copy. See the ARM -widen-vmovs option. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141578 91177308-0d34-0410-b5e6-96231b3b80d8
* Add target hook for pseudo instruction expansion.Jakob Stoklund Olesen2011-09-251-7/+16
| | | | | | | | | | | | Many targets use pseudo instructions to help register allocation. Like the COPY instruction, these pseudos can be expanded after register allocation. The early expansion can make life easier for PEI and the post-ra scheduler. This patch adds a hook that is called for all remaining pseudo instructions from the ExpandPostRAPseudos pass. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@140472 91177308-0d34-0410-b5e6-96231b3b80d8
* Clean up code after renaming LowerSubregs -> ExpandPostRAPseudos.Jakob Stoklund Olesen2011-09-251-43/+40
| | | | | | No functional change intended. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@140470 91177308-0d34-0410-b5e6-96231b3b80d8
* Rename LowerSubregs to ExpandPostRAPseudos.Jakob Stoklund Olesen2011-09-251-0/+223
I'll fix the file contents in the next commit. This pass is currently expanding the COPY and SUBREG_TO_REG pseudos. I am going to add a hook so targets can expand more pseudo-instructions after register allocation. Many targets have pseudo-instructions that assist the register allocator. They can be expanded after register allocation, before PEI and PostRA scheduling. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@140469 91177308-0d34-0410-b5e6-96231b3b80d8
