Nobody cared, StackSlotColoring scans the instructions to find used stack slots. llvm-svn: 144485

Most of this stuff was supporting the old deferred spill code insertion mechanism. Modern spillers just edit machine code in place. llvm-svn: 144484

The information was only used by the register allocator in StackSlotColoring. llvm-svn: 144482

It was off by default. The new register allocators don't have the problems that made it necessary to reallocate registers during stack slot coloring. llvm-svn: 144481

This is dead code, all register allocators use InlineSpiller. llvm-svn: 144478

The current register allocators all use the inline spiller. llvm-svn: 144477

It is worth noting that the old spiller would split live ranges around basic blocks. The new spiller doesn't do that. PBQP should do its own live range splitting with SplitEditor::splitSingleBlock() if desired. See RAGreedy::tryBlockSplit(). llvm-svn: 144476

RegAllocGreedy has been the default for six months now. Deleting RegAllocLinearScan makes it possible to also delete VirtRegRewriter and clean up the spiller code. llvm-svn: 144475

Counting the number of occurences of each opcode is not a useful test. llvm-svn: 144474

This test was committed with a bugfix to RemoveCopyByCommutingDef, but that optimization is no longer triggered by this test. llvm-svn: 144470

This test is for a very specific LocalRewriter bug. LocalRewriter is going away. llvm-svn: 144469

I don't think this test does what is was supposed to do, and LocalRewriter is going away anyway. llvm-svn: 144463

The test is checking that the output doesn't contains any 'mov ' strings. It does contain movl, though. llvm-svn: 144458

methods but also class methods for Objective-C. Clang emits Objective-C method names with '\1' at the beginning, and the JIT has pre-existing logic to try prepending a '\1' when searching a module for an instance method (that is, a method whose name begins with '-'). I simply extended it to do the same thing when it encountered a class method (a method whose name begins with '+'). llvm-svn: 144451

instance and a concrete inlined instance are the use of DW_TAG_subprogram instead of DW_TAG_inlined_subroutine and the who owns the tree. We were also omitting DW_AT_inline from the abstract roots. To fix this, make sure we mark abstract instance roots with DW_AT_inline even when we have only out-of-line instances referring to them with DW_AT_abstract_origin. FileCheck is not a very good tool for tests like this, maybe we should add a -verify mode to llvm-dwarfdump. llvm-svn: 144441

Some cleanup and bulletproofing for node replacement in LegalizeDAG. To maintain LegalizeDAG invariants, whenever we a node is replaced, we must attempt to delete it, and if it still has uses after it is replaced (which can happen in rare cases due to CSE), we must revisit it. llvm-svn: 144432
