2012-06-23Extend the IL for selecting TLS models (PR9788)Hans Wennborg
This allows the user/front-end to specify a model that is better than what LLVM would choose by default. For example, a variable might be declared as @x = thread_local(initialexec) global i32 42 if it will not be used in a shared library that is dlopen'ed. If the specified model isn't supported by the target, or if LLVM can make a better choice, a different model may be used. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159077 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-23Teach LiveVariables to handle <undef> operands.Jakob Stoklund Olesen
It's simple: Don't treat <undef> operands as uses, and don't assume a virtual register has a defining instruction unless a real use has been seen. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159061 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-23(sub X, imm) gets canonicalized to (add X, -imm)Evan Cheng
There are patterns to handle immediates when they fit in the immediate field. e.g. %sub = add i32 %x, -123 => sub r0, r0, #123 Add patterns to catch immediates that do not fit but should be materialized with a single movw instruction rather than movw + movt pair. e.g. %sub = add i32 %x, -65535 => movw r1, #65535 sub r0, r0, r1 rdar://11726136 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159057 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-22ARM: Add a better diagnostic for some out of range immediates.Jim Grosbach
As an example of how the custom DiagnosticType can be used to provide better operand-mismatch diagnostics, add a custom diagnostic for the imm0_15 operand class used for several system instructions. Update the tests to expect the improved diagnostic. rdar://8987109 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159051 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-22TableGen: AsmMatcher support for better operand diagnostics.Jim Grosbach
"Invalid operand" may be a completely correct diagnostic, but it's often insufficiently specific to really help identify and fix the problem in assembly source. Allow a target to specify a more-specific diagnostic kind for each AsmOperandClass derived definition and use that to provide more detailed diagnostics when an operant of that class resulted in a match failure. rdar://8987109 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159050 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-22Use regunit liveness to guide LiveDebugVariables.Jakob Stoklund Olesen

With regunit liveness permanently enabled, this function would always return true. Also remove now obsolete code for checking physreg interference. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159006 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-22Revert remaining part of r93200: "Disable folding sext(trunc(x)) -> x"Jakob Stoklund Olesen
This fixes PR5997. These transforms were disabled because codegen couldn't deal with other uses of trunc(x). This is now handled by the peephole pass. This causes no regressions on x86-64. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159003 91177308-0d34-0410-b5e6-96231b3b80d8

It allows to make faster access to individual case value numbers or ranges. - Optimized IntItem, added APInt value caching. - Optimized IntegersSubsetGeneric: added optimizations for cases when subset is single number or when subset consists from single numbers only.

2012-06-22Use "NoItineraries" for processors with no itineraries.Andrew Trick
This makes it explicit when ScoreboardHazardRecognizer will be used. "GenericItineraries" would only make sense if it contained real itinerary values and still required ScoreboardHazardRecognizer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158963 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-22Functions calling __builtin_eh_return must have a frame pointer.Jakob Stoklund Olesen
The code in X86TargetLowering::LowerEH_RETURN() assumes that a frame pointer exists, but the frame pointer was forced by the presence of llvm.eh.unwind.init which isn't guaranteed. If llvm.eh.unwind.init is actually required in functions calling eh.return (is it?), we should diagnose that instead of emitting bad machine code. This should fix the dragonegg-x86_64-linux-gcc-4.6-test bot. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158961 91177308-0d34-0410-b5e6-96231b3b80d8
