* implement and document support for filecheck variables. ThisChris Lattner2009-09-271-43/+172
| | | | | | | | | | | allows matching and remembering a string and then matching and verifying that the string occurs later in the file. Change X86/xor.ll to use this in some cases where the test was checking for an arbitrary register allocation decision. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82891 91177308-0d34-0410-b5e6-96231b3b80d8

* Improve MachineMemOperand handling.Dan Gohman2009-09-251-18/+11
| | | | | | | | | | | | | | | | | | | | | | - Allocate MachineMemOperands and MachineMemOperand lists in MachineFunctions. This eliminates MachineInstr's std::list member and allows the data to be created by isel and live for the remainder of codegen, avoiding a lot of copying and unnecessary translation. This also shrinks MemSDNode. - Delete MemOperandSDNode. Introduce MachineSDNode which has dedicated fields for MachineMemOperands. - Change MemSDNode to have a MachineMemOperand member instead of its own fields with the same information. This introduces some redundancy, but it's more consistent with what MachineInstr will eventually want. - Ignore alignment when searching for redundant loads for CSE, but remember the greatest alignment. Target-specific code which previously used MemOperandSDNodes with generic SDNodes now use MemIntrinsicSDNodes, with opcodes in a designated range so that the SelectionDAG framework knows that MachineMemOperand information is available. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82794 91177308-0d34-0410-b5e6-96231b3b80d8

* reimplement the regex matching strategy by building a singleChris Lattner2009-09-251-88/+51
| | | | | | | | | | | | | | | | | | | regex and matching it instead of trying to match chunks at a time. Matching chunks at a time broke with check lines like CHECK: foo {{.*}}bar because the .* would eat the entire rest of the line and bar would never match. Now we just escape the fixed strings for the user, so that something like: CHECK: a() {{.*}}??? is matched as: CHECK: {{a\(\) .*\?\?\?}} transparently "under the covers". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82779 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | the MCInst path of the asmprinter. Instead, pull comment printing out of the autogenerated asmprinter into each target that uses the autogenerated asmprinter. This causes code duplication into each target, but in a way that will be easier to clean up later when more asmprinter stuff is commonized into the base AsmPrinter class. This also fixes an xcore strangeness where it inserted two tabs before every instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81396 91177308-0d34-0410-b5e6-96231b3b80d8

This fixes a problem where the experimental asmprinter would drop debug labels in some cases, and fixes issues on ppc/xcore where pseudo instructions like "mr" didn't get debug locs properly. It is annoying that this moves the call from one place into each target, but a future set of more invasive refactorings will fix that problem. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81377 91177308-0d34-0410-b5e6-96231b3b80d8
