* Fix verifier for GlobalAliases to avoid recursing into global initializers.Bob Wilson2014-06-122-0/+8
| | | | | | | | | | | The verifier follows GlobalAlias operands so that it can detect cycles of alias definitions. It was doing this in a way that caused it to also recurse through initializers for the GlobalValue aliasees, and it would fail when an initializer refers to a global that is a declaration and not a definition. This patch causes it to stop recursing when it hits a global definition. <rdar://problem/17277451> llvm-svn: 210734

* Do not register and de-register PassRegistrationListeners duringZachary Turner2014-06-123-23/+14
| | | | | | | | | | | | | | | | | construction and destruction. PassRegistrationListener is intended for use as a generic listener. In some cases, PassRegistrationListener-derived classes were being created, and automatically registered and de-registered in static constructors and destructors. Since ManagedStatics are destroyed prior to program shutdown, this leads to errors where an attempt is made to access a ManagedStatic that has already been destroyed.

* Don't acquire the mutex during the destructor of PassRegistry.Zachary Turner2014-06-111-1/+4
| | | | | | | | | | | This destructor is run as part of static program termination, and so all ManagedStatics (including this lock) will have been destroyed by llvm_shutdown. Furthermore, if there is actually a race condition during static program termination, then we are just hiding a bug somewhere else, because other threads should not be running at this point. llvm-svn: 210717

* ARM: honor hex immediate formatting for ldr/str i12 offsets.Jim Grosbach2014-06-112-2/+8
| | | | | | | | | | | | | | | | | Previously we would always print the offset as decimal, regardless of the formatting requested. Now we use the formatImm() helper so the value is printed as the client (LLDB in the motivating example) requested. Before: ldr.w r8, [sp, #180] @ always After: ldr.w r8, [sp, #0xb4] @ when printing hex immediates ldr.w r8, [sp, #0180] @ when printing decimal immediates rdar://17237103 llvm-svn: 210701
* llvm-mc: Add option for prefering hex format disassembly.Jim Grosbach2014-06-114-14/+14
| | | | | | | | | Previously there was a separate mode entirely (--hdis vs. --disassemble). It makes a bit more sense for the immediate printing style to be a flag for --disassmeble rather than an entirely different thing. llvm-svn: 210700

| | | | | | | | | | This is the same problem fixed in r210664 for more types. The test passes without this fix. For some reason I'm only hitting this when creating selects lowered to v2i32 selects. llvm-svn: 210692
* Use std::error_code instead of llvm::error_code.Rafael Espindola2014-06-1137-1142/+217
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The idea of this patch is to turn llvm/Support/system_error.h into a transitional header that just brings in the erorr_code api to the llvm namespace. I will remove it shortly afterwards. The cases where the general idea needed some tweaking: * std::errc is a namespace in msvc, so we cannot use "using std::errc". I could add an #ifdef, but there were not that many uses, so I just added std:: to them in this patch. * Template specialization had to be moved to the std namespace in this patch set already. * The msvc implementation of default_error_condition doesn't seem to provide the same transformations as we need. Not too surprising since the standard doesn't actually say what "equivalent" means. I fixed the problem by keeping our old mapping and using it at error_code construction time. Despite these shortcomings I think this is still a good thing. Some reasons: * The different implementations of system_error might improve over time. * It removes 925 lines of code from llvm already. * It removes 6313 bytes from the text segment of the clang binary when it is built with gcc and 2816 bytes when building with clang and libstdc++. llvm-svn: 210687

* [X86] Refactor the logic to select horizontal adds/subs to a helper function.Andrea Di Biagio2014-06-112-108/+201
| | | | | | | | | | | | | | | This patch moves part of the logic implemented by the target specific combine rules added at r210477 to a separate helper function. This should make easier to add more rules for matching AVX/AVX2 horizontal adds/subs. This patch also fixes a problem caused by a wrong check performed on indices of extract_vector_elt dag nodes in input to the scalar adds/subs. New tests have been added to verify that we correctly check indices of extract_vector_elt dag nodes when selecting a horizontal operation. llvm-svn: 210644

* MC: add enumeration of WinEH data encodingSaleem Abdulrasool2014-06-112-2/+21
| | | | | | | | | | | | | | | Most Windows platforms use auxiliary data for unwinding. This information is stored in the .pdata section. The encoding format for the data differs between architectures and Windows variants. Windows MIPS and Alpha use identical formats; Alpha64 is the same with different widths. Windows x86_64 and Itanium share the representation. All Windows CE entries are identical irrespective of the architecture. ARMv7 (Windows [NT] on ARM) has its own format. This enumeration will become the differentiator once the windows EH emission infrastructure is generalised, allowing us to emit the necessary unwinding information for Windows on ARM. llvm-svn: 210634
