2017-10-03[X86] Provide the LSDA pointer with RIP relative addressing if necessaryMartin Storsjo
This makes sure the LSDA pointer isn't truncated to 32 bit. Make LowerINTRINSIC_WO_CHAIN a member function instead of a static function, so that it can use the getGlobalWrapperKind method.

2017-10-03[Lint] Avoid failed assertion by fetching the proper pointer typeMikael Holmen
Summary: When checking if a constant expression is a noop cast we fetched the IntPtrType by doing DL->getIntPtrType(V->getType())). However, there can be cases where V doesn't return a pointer, and then getIntPtrType() triggers an assertion. Now we pass DataLayout to isNoopCast so the method itself can determine what the IntPtrType is.

2017-10-03AMDGPU: Remove global isGCN predicatesMatt Arsenault
These are problematic because they apply to everything, and can easily clobber whatever more specific predicate you are trying to add to a function. Currently instructions use SubtargetPredicate/PredicateControl to apply this to patterns applied to an instruction definition, but not to free standing Pats. Add a wrapper around Pat so the special PredicateControls requirements can be appended to the final predicate list like how Mips does it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@314742 91177308-0d34-0410-b5e6-96231b3b80d8

2017-10-02Re-enable "[MachineCopyPropagation] Extend pass to do COPY source forwarding"Geoff Berry
Issues addressed since original review: - Avoid bug in regalloc greedy/machine verifier when forwarding to use in an instruction that re-defines the same virtual register. - Fixed bug when forwarding to use in EarlyClobber instruction slot. - Fixed incorrect forwarding to register definitions that showed up in explicit_uses() iterator (e.g. in INLINEASM). - Moved removal of dead instructions found by LiveIntervals::shrinkToUses() outside of loop iterating over instructions to avoid instructions being deleted while pointed to by iterator. - Fixed ARMLoadStoreOptimizer bug exposed by this change in r311907. - The pass no longer forwards COPYs to physical register uses, since doing so can break code that implicitly relies on the physical register number of the use. - The pass no longer forwards COPYs to undef uses, since doing so can break the machine verifier by creating LiveRanges that don't end on a use (since the undef operand is not considered a use). [MachineCopyPropagation] Extend pass to do COPY source forwarding This change extends MachineCopyPropagation to do COPY source forwarding. This change also extends the MachineCopyPropagation pass to be able to be run during register allocation, after physical registers have been assigned, but before the virtual registers have been re-written, which allows it to remove virtual register COPY LiveIntervals that become dead through the forwarding of all of their uses. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@314729 91177308-0d34-0410-b5e6-96231b3b80d8

2017-10-02Move the stripping of invalid debug info from the Verifier to AutoUpgrade.Adrian Prantl
This came out of a recent discussion on llvm-dev (https://reviews.llvm.org/D38042). Currently the Verifier will strip the debug info metadata from a module if it finds the dbeug info to be malformed. This feature is very valuable since it allows us to improve the Verifier by making it stricter without breaking bcompatibility, but arguable the Verifier pass should not be modifying the IR. This patch moves the stripping of broken debug info into AutoUpgrade (UpgradeDebugInfo to be precise), which is a much better location for this since the stripping of malformed (i.e., produced by older, buggy versions of Clang) is a (harsh) form of AutoUpgrade. This change is mostly NFC in nature, the one big difference is the behavior when LLVM module passes are introducing malformed debug info. Prior to this patch, a NoAsserts build would have printed a warning and stripped the debug info, after this patch the Verifier will report a fatal error. I believe this behavior is actually more desirable anyway.
