* Support: Move OnDiskHashTable from clang to llvmJustin Bogner2014-04-17
| | | | | | | | | This introduces clang's Basic/OnDiskHashTable.h into llvm as Support/OnDiskHashTable.h. I've taken the opportunity to add doxygen comments and run the file through clang-format, but other than the namespace changing from clang:: to llvm:: the API is identical. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@206438 91177308-0d34-0410-b5e6-96231b3b80d8

* [mips] Add initial support for NaN2008 in the back-end.Matheus Almeida2014-04-16
| | | | | | | | | | | | | This is so that EF_MIPS_NAN2008 is set if we are using IEEE 754-2008 NaN encoding (-mnan=2008). This patch also adds support for parsing '.nan legacy' and '.nan 2008' assembly directives. The handling of these directives should match GAS' behaviour i.e., the last directive in use sets the ELF header bit (EF_MIPS_NAN2008).

* verify-di: Implement DebugInfoVerifierDuncan P. N. Exon Smith2014-04-15
| | | | | | | | | | | | | | | | | | | | | Implement DebugInfoVerifier, which steals verification relying on DebugInfoFinder from Verifier. - Adds LegacyDebugInfoVerifierPassPass, a ModulePass which wraps DebugInfoVerifier. Uses -verify-di command-line flag. - Change verifyModule() to invoke DebugInfoVerifier as well as Verifier. - Add a call to createDebugInfoVerifierPass() wherever there was a call to createVerifierPass(). This implementation as a module pass should sidestep efficiency issues, allowing us to turn debug info verification back on. <rdar://problem/15500563> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@206300 91177308-0d34-0410-b5e6-96231b3b80d8
* FastISel: constrain the RegClass of operands when emitting instructions.Tim Northover2014-04-15
| | | | | | | | | | | ARM64 suffered multiple -verify-machineinstr failures (principally over the xsp/xzr issue) because FastISel was completely ignoring which subset of the general-purpose registers each instruction required.

* [Allocator] Finally, finish nuking the redundant code that led me hereChandler Carruth2014-04-15
| | | | | | | | | | | | | | | | by removing the MallocSlabAllocator entirely and just using MallocAllocator directly. This makes all off these allocators expose and utilize the same core interface. The only ugly part of this is that it exposes the fact that the JIT allocator has no real handling of alignment, any more than the malloc allocator does. =/ It would be nice to fix both of these to support alignments, and then to leverage that in the BumpPtrAllocator to do less over allocation in order to manually align pointers. But, that's another patch for another day. This patch has no functional impact, it just removes the somewhat meaningless wrapper around MallocAllocator. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@206267 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | allocation libraries, may allow more efficient allocation and deallocation. It at least makes the interface implementable by the JIT memory manager. However, this highlights problematic overloading between the void* and the T* deallocation functions.

* [MC] Require an MCContext when constructing an MCDisassembler.Lang Hames2014-04-15
| | | | | | | | | | | | | | | | | | This patch re-introduces the MCContext member that was removed from MCDisassembler in r206063, and requires that an MCContext be passed in at MCDisassembler construction time. (Previously the MCContext member had been initialized in an ad-hoc fashion after construction). The MCCContext member can be used by MCDisassembler sub-classes to construct constant or target-specific MCExprs. This patch updates disassemblers for in-tree targets, and provides the MCRegisterInfo instance that some disassemblers were using through the MCContext (previously those backends were constructing their own MCRegisterInfo instances). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@206241 91177308-0d34-0410-b5e6-96231b3b80d8

* [Allocator] Factor the Allocate template overloads into a base classChandler Carruth2014-04-15
| | | | | | | | | | | | | | | | | | | | rather than defining them (differently!) in both allocators. This also serves as a basis for documenting and even enforcing some of the LLVM-style "allocator" concept methods which must exist with various signatures. I plan on extending and changing the signatures of these to further simplify our allocator model in subsequent commits, so I wanted to factor things as best as I could first. Notably, I'm working to add the 'Size' to the deallocation method of all allocators. This has several implications not the least of which are faster deallocation times on certain allocation libraries (tcmalloc). It also will allow the JIT allocator to fully model the existing allocation interfaces and allow sanitizer poisoning of deallocated regions. The list of advantages goes on. =] But by factoring things first I'll be able to make this easier by first introducing template helpers for the deallocation path. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@206225 91177308-0d34-0410-b5e6-96231b3b80d8

The latter is the really nice part. Folks have complained from time to time bitterly that tearing down a BumpPtrAllocator, even if it doesn't run any destructors, pages in all of the memory allocated.
