* libLTO: Add a utility method to initialize the disassemblers.Benjamin Kramer2012-11-24
| | | | | | | | | | | | Necessary to give disassembler users (like darwin's otool) a possibility to dlopen libLTO and still initialize the required LLVM bits. This used to go through libMCDisassembler but that's a gross layering violation, the MC layer can't pull in functions from the targets. Adding a function to libLTO is a bit of a hack but not worse than exposing other disassembler bits from libLTO. Fixes PR14362. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168545 91177308-0d34-0410-b5e6-96231b3b80d8
* Change the representation of MCCFIInstruction.Rafael Espindola2012-11-24

* Give each MCCFIInstruction its own opcode.Rafael Espindola2012-11-24
| | | | | | | This untangles the switch cases of the old Move and RelMove opcodes a bit and makes it clear how to add new instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168534 91177308-0d34-0410-b5e6-96231b3b80d8

* Refactor how MCCFIInstructions are created.Rafael Espindola2012-11-24
| | | | | | | | | | Give MCCFIInstruction a single, private constructor and add helper static methods that create each type of cfi instruction. This is is preparation for changing its representation. The representation with a pair MachineLocations older than MC and has been abused quiet a bit to support more cfi instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168532 91177308-0d34-0410-b5e6-96231b3b80d8

* Make the AttrListPtr object a part of the LLVMContext.Bill Wendling2012-11-20
| | | | | | | | | | When code deletes the context, the AttributeImpls that the AttrListPtr points to are now invalid. Therefore, instead of keeping a separate managed static for the AttrListPtrs that's reference counted, move it into the LLVMContext and delete it when deleting the AttributeImpls. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168354 91177308-0d34-0410-b5e6-96231b3b80d8

* Clean up handling of always-inline functions in the inliner.Bob Wilson2012-11-19
| | | | | | | | | This patch moves the isInlineViable function from the InlineAlways pass into the InlineCostAnalyzer and then changes the InlineCost computation to use that simple check for always-inline functions. All the special-case checks for AlwaysInline in the CallAnalyzer can then go away. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168300 91177308-0d34-0410-b5e6-96231b3b80d8

* [reg scavenger] Fix the isUsed/isAliasUsed functions so as to not report a falseChad Rosier2012-11-15
| | | | | | | | | | | | | | | | | positive. In this particular case, R6 was being spilled by the register scavenger when it was in fact dead. The isUsed function reported R6 as used because the R6_R7 alias was reserved (due to the fact that we've reserved R7 as the FP). The solution is to only check if the original register (i.e., R6) isReserved and not the aliases. The aliases are only checked to make sure they're available. The test case is derived from one of the nightly tester benchmarks and is rather intractable and difficult to reproduce, so I haven't included it. rdar://12592448 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168054 91177308-0d34-0410-b5e6-96231b3b80d8

* Make GlobalOpt be conservative with TLS variables (PR14309)Hans Wennborg2012-11-15
| | | | | | | | | | | | | | For global variables that get the same value stored into them everywhere, GlobalOpt will replace them with a constant. The problem is that a thread-local GlobalVariable looks like one value (the address of the TLS var), but is different between threads. This patch introduces Constant::isThreadDependent() which returns true for thread-local variables and constants which depend on them (e.g. a GEP into a thread-local array), and teaches GlobalOpt not to track such values. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168037 91177308-0d34-0410-b5e6-96231b3b80d8
