2013-01-10Add basic fix-its to SMDiagnostic.Jordan Rose
Like Clang's FixItHint, SMFixIt represents an insertion, replacement, or removal of source text. One or more fix-its can be emitted as part of a diagnostic, and will be printed below the source range line to show the user how they can fix their code. Currently, the only client of SMFixIt is clang-tblgen; thus, the tests for this behavior live in clang/test/TableGen/tg-fixits.td. If/when SMFixIt is adopted within LLVM itself, those tests should be moved to the LLVM suite. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172086 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-10Allow hasProperty() to be called on bundle-internal instructions.Jakob Stoklund Olesen
When calling hasProperty() on an instruction inside a bundle, it should always behave as if IgnoreBundle was passed, and just return properties for the current instruction. Only attempt to aggregate bundle properties whan asked about the bundle header. The assertion fires on existing ARM test cases without this fix. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172082 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-10Fix Alias BugDavid Greene

2013-01-10Make TableGen mangle operand method names before putting in enum.Tim Northover
The purpose of this patch is to allow PredicateMethods to be set to something like "isUImm<8>", calling a C++ template method to reduce code duplication. For this to work, the PredicateMethod must be mangled into a valid C++ identifier for insertion into an enum. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172073 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-10Stack Alignment: throw error if we can't satisfy the minimal alignmentManman Ren
requirement when creating stack objects in MachineFrameInfo. Add CreateStackObjectWithMinAlign to throw error when the minimal alignment can't be achieved and to clamp the alignment when the preferred alignment can't be achieved. Same is true for CreateVariableSizedObject. Will not emit error in CreateSpillStackObject or CreateStackObject. As long as callers of CreateStackObject do not assume the object will be aligned at the requested alignment, we should not have miscompile since later optimizations which look at the object's alignment will have the correct information. rdar://12713765 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172027 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-09For some LLVM-as-library uses it is convenient to create aDavid Tweed
subclass of TargetMachine which "forwards" all operations to an existing internal TargetMachine member variable. In the usage context the specific-machine class derived from TargetMachine is not visible, only a reference to the generic base class TargetMachine. Although getSubtargetImpl() is public in specific-machine classes derived from TargetMachine, the TargetMachine class unfortunately has getSubtargetImpl() protected (and accessing non-const members makes abusing getSubtarget() unsuitable). Making it public in the base class allows this forwarding pattern. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171976 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-09Configure: if we compile with clang, check that it is not brokenDmitri Gribenko
Some linux distibutions (for example, Mageia 2, Fedora 17) ship Clang that is essentially broken for the end user. Clang can not find or compile libstdc++ headers. The issue is that our configure prefers clang over gcc, thus selecting a broken Clang when a working GCC is available. Now we detect this issue by compiling a simple program. If it does not compile, configure stops with an error suggesting the user to select a different compiler. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171975 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-09Check whether MCInst operand isImm before calling getImm.Tim Northover
When processing possible aliases, TableGen assumes that if an operand *can* be an immediate, then it always *will* be. This is incorrect for the AArch64 backend. This patch inserts a check in the generated code to make sure isImm is true first. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171972 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-09Refactor to expose RTLIB calls to targets.Tim Northover
fp128 is almost but not quite completely illegal as a type on AArch64. As a result it needs to have a register class (for argument passing mainly), but all operations need to be lowered to runtime calls. Currently there's no way for targets to do this (without duplicating code), as the relevant functions are hidden in SelectionDAG. This patch changes that. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171971 91177308-0d34-0410-b5e6-96231b3b80d8
