* [modules] Re-enable the "ambiguous expansion of macro" warning.Argyrios Kyrtzidis2013-03-272-25/+24
| | | | | | | | | | Also update "test/Modules/macros.c" to test modified semantics: -When there is an ambiguous macro, expand using the latest introduced version, not the first one. -#undefs in submodules cause the macro to not be exported by that submodule, it doesn't cause undefining of macros in the translation unit that imported that submodule. This reduces macro namespace interference across modules. llvm-svn: 178105

* Added back in the test for arc-annotations.Michael Gottesman2013-03-271-0/+307
| | | | | | | | | The test was removed since I had not turned off the test during release builds. This fails since ARC annotations support is conditionally compiled out during release builds. I added the proper requires header to assuage this issue. llvm-svn: 178101
* Update debug info test for schema change made to LLVM.David Blaikie2013-03-271-3/+3

* Adding DIImportedModules to DIScopes.David Blaikie2013-03-2799-1354/+1473
| | | | | | | | | | | | This is just the basic groundwork for supporting DW_TAG_imported_module but I wanted to commit this before pushing support further into Clang or LLVM so that this rather churny change is isolated from the rest of the work. The major churn here is obviously adding another field (within the common DIScope prefix) to all DIScopes (files, classes, namespaces, lexical scopes, etc). This should be the last big churny change needed for DW_TAG_imported_module/using directive support/PR14606. llvm-svn: 178099

* Split "incomplete implementation" warnings for ObjC into separate warnings.Ted Kremenek2013-03-2718-74/+73
| | | | | | | | | | | | Previously all unimplemented methods for a class were grouped under a single warning, with all the unimplemented methods mentioned as notes. Based on feedback from users, most users would like a separate warning for each method, with a note pointing back to the original method declaration. Implements <rdar://problem/13350414> llvm-svn: 178097
* Don't spill PPC VRSAVE on non-Darwin (even in SjLj)Hal Finkel2013-03-275-6/+18
| | | | | | | | | | | | | As Bill Schmidt pointed out to me, only on Darwin do we need to spill/restore VRSAVE in the SjLj code. For non-Darwin, don't spill/restore VRSAVE (and I've added some asserts to make sure that we're not). As it turns out, we're not currently handling the Darwin case correctly (I've added a FIXME in the test case). I've tried adding various implied register definitions/uses to force the spill without success, so I'll need to address this later. llvm-svn: 178096

* <rdar://problem/13267210> Ensure that Sema::CompareReferenceRelationship ↵Douglas Gregor2013-03-264-17/+43
| | | | | | | | | | | | | returns consistent results with invalid types. When Sema::RequireCompleteType() is given a class template specialization type that then fails to instantiate, it returns 'true'. On subsequent invocations, it can return false. Make sure that this difference doesn't change the result of Sema::CompareReferenceRelationship, which is expected to remain stable while we're checking an initialization sequence. llvm-svn: 178088
* Add a boolean parameter to the ExecuteAndWait static function to indicatedChad Rosier2013-03-262-5/+9
| | | | | | | | | | if execution failed. ExecuteAndWait returns -1 upon an execution failure, but checking the return value isn't sufficient because the wait command may return -1 as well. This new parameter is to be used by the clang driver in a subsequent commit. Part of rdar://13362359 llvm-svn: 178087

* Use the full path when outputting the `.gcda' file.Bill Wendling2013-03-261-5/+14
| | | | | | | | | | | | | | If we compile a single source program, the `.gcda' file will be generated where the program was executed. This isn't desirable, because that place may be at an unpredictable place (the program could call `chdir' for instance). Instead, we will output the `.gcda' file in the same place we output the `.gcno' file. I.e., the directory where the executable was generated. This matches GCC's behavior. <rdar://problem/13061072> & PR11809 llvm-svn: 178084

* Enable SandyBridgeModel for all modern Intel P6 descendants.Jakob Stoklund Olesen2013-03-264-37/+47
| | | | | | | | | | | | All Intel CPUs since Yonah look a lot alike, at least at the granularity of the scheduling models. We can add more accurate models for processors that aren't Sandy Bridge if required. Haswell will probably need its own. The Atom processor and anything based on NetBurst is completely different. So are the non-Intel chips. llvm-svn: 178080

* Restore real bit lengths on PPC register numbersHal Finkel2013-03-261-12/+12
| | | | | | | | | | As suggested by Bill Schmidt (in reviewing r178067), use the real register number bit lengths (which is self-documenting, and prevents using illegal numbers), and set only the relevant bits in HWEncoding (which defaults to 0). No functionality change intended. llvm-svn: 178077

* Fix the register scavenger for targets that provide custom spillingHal Finkel2013-03-262-4/+8
| | | | | | | | | | | As pointed out by Richard Sandiford, my recent updates to the register scavenger broke targets that use custom spilling (because the new code assumed that if there were no valid spill slots, than spilling would be impossible). I don't have a test case, but it should be possible to create one for Thumb 1, Mips 16, etc. llvm-svn: 178073

* PPC: Use HWEncoding and TRI->getEncodingValueHal Finkel2013-03-268-100/+31
| | | | | | | | | | | As pointed out by Jakob, we don't need to maintain a separate register-numbering table. Instead we should let TableGen generate the table for us from the information (already present) in PPCRegisterInfo.td. TRI->getEncodingValue is now used to access register-encoding values. No functionality change intended. llvm-svn: 178067

* Use multiple virtual registers in PPC CR spillingHal Finkel2013-03-263-42/+58
| | | | | | | | | | | | Now that the register scavenger can support multiple spill slots, and PEI can use virtual-register-based scavenging for multiple simultaneous registers, we can use a virtual register for the transfer register in the CR spilling code. This should eliminate the last place (outside of the prologue/epilogue) where we depend on the unconditional availability of the r0 register. We will soon be able to allocate it (in a somewhat restricted sense) as a GPR. llvm-svn: 178060
* Update PPCRegisterInfo's use of virtual registers to be SSAHal Finkel2013-03-261-3/+5
| | | | | | | | | | | PPC's use of PEI's virtual-register-based scavenging functionality had redefined the virtual registers (it was non-SSA). Now that PEI supports dealing with instructions with multiple virtual registers, this can be cleanup up to use multiple virtual registers and keep SSA form. No functionality change intended. llvm-svn: 178059
* Update PEI's virtual-register-based scavenging to support multiple ↵Hal Finkel2013-03-264-27/+43
| | | | | | | | | | | | | | | | | | | simultaneous mappings The previous algorithm could not deal properly with scavenging multiple virtual registers because it kept only one live virtual -> physical mapping (and iterated through operands in order). Now we don't maintain a current mapping, but rather use replaceRegWith to completely remove the virtual register as soon as the mapping is established. In order to allow the register scavenger to return a physical register killed by an instruction for definition by that same instruction, we now call RS->forward(I) prior to eliminating virtual registers defined in I. This requires a minor update to forward to ignore virtual registers. These new features will be tested in forthcoming commits. llvm-svn: 178058
