Craig Topper dbe8b7d236 Put HasAVX512 predicate on some patterns to properly disable them when AVX512 isn't enabled. Currently it works simply because the SSE and AVX version of the same patterns are checked first in the DAG isel table.

David Majnemer 143c55ead2 AST: Handle qualified array types in typeid() expressions
The intent of getTypeOperand() was to yield an unqualified type.
However QualType::getUnqualifiedType() does not strip away qualifiers on
arrays.

N.B.  This worked fine when typeid() was applied to an expression
because we would inject as implicit cast to the unqualified array type
in the AST.

David Majnemer c185aa7d92 Sema: Respect -fdelayed-template-parsing when parsing constexpr functions
Functions declared as constexpr must have their parsing delayed in
-fdelayed-template-parsing mode so as not to upset later template
instantiation.

N.B. My reading of the standard makes it seem like delayed template
parsing is at odds with constexpr.  We may want to make refinements in
other places in clang to make constexpr play nicer with this feature.

This fixes PR17334.

as if they had the same line number as whatever we were previously stepping through.

Rui Ueyama 5b1adbaad9 llvm-objdump: Dump COFF import table if -private-headers option is given.
This is a patch to add capability to llvm-objdump to dump COFF Import Table
entries, so that we can write tests for LLD checking Import Table contents.

llvm-objdump did not print anything but just file name if the format is COFF
and -private-headers option is given. This is a patch adds capability for
dumping DLL Import Table, which is specific to the COFF format.

In this patch I defined a new iterator to iterate over import table entries.
Also added a few functions to COFFObjectFile.cpp to access fields of the entry.

Matt Kopec cc64cc1773 Fix the thread jump test case for 32-bit inferiors. A jump was going back to a function call using a source line number. However, the parameters being passed to the function were setup before the instruction we jumped to. In other words, the source line was associated with assembly after the function parameters had been setup for the function to be called.

Faisal Vali 2b391ab708 Implement a rudimentary form of generic lambdas.
Specifically, the following features are not included in this commit:
  - any sort of capturing within generic lambdas 
  - generic lambdas within template functions and nested 
    within other generic lambdas
  - conversion operator for captureless lambdas
  - ensuring all visitors are generic lambda aware
  (Although I have gotten some useful feedback on my patches of the above and will be incorporating that as I submit those patches for commit)

As an example of what compiles through this commit:

template <class F1, class F2>
struct overload : F1, F2 {
    using F1::operator();
    using F2::operator();
    overload(F1 f1, F2 f2) : F1(f1), F2(f2) { }
  };

  auto Recursive = [](auto Self, auto h, auto ... rest) {
    return 1 + Self(Self, rest...);
  };
  auto Base = [](auto Self, auto h) {
      return 1;
  };
  overload<decltype(Base), decltype(Recursive)> O(Base, Recursive);
  int num_params =  O(O, 5, 3, "abc", 3.14, 'a');

Please see attached tests for more examples.

This patch has been reviewed by Doug and Richard.  Minor changes (non-functionality affecting) have been made since both of them formally looked at it, but the changes involve removal of supernumerary return type deduction changes (since they are now redundant, with richard having committed a recent patch to address return type deduction for C++11 lambdas using C++14 semantics). 



Some implementation notes:

  - Add a new Declarator context => LambdaExprParameterContext to 
    clang::Declarator to allow the use of 'auto' in declaring generic
    lambda parameters
      
  - Add various helpers to CXXRecordDecl to facilitate identifying
    and querying a closure class
  
  - LambdaScopeInfo (which maintains the current lambda's Sema state)
    was augmented to house the current depth of the template being
    parsed (id est the Parser calls Sema::RecordParsingTemplateParameterDepth)
    so that SemaType.cpp::ConvertDeclSpecToType may use it to immediately 
    generate a template-parameter-type when 'auto' is parsed in a generic
    lambda parameter context.  (i.e we do NOT use AutoType deduced to 
    a template parameter type - Richard seemed ok with this approach).  
    We encode that this template type was generated from an auto by simply
    adding $auto to the name which can be used for better diagnostics if needed.

  - SemaLambda.h was added to hold some common lambda utility
    functions (this file is likely to grow ...)
    
  - Teach Sema::ActOnStartOfFunctionDef to check whether it
    is being called to instantiate a generic lambda's call
    operator, and if so, push an appropriately prepared
    LambdaScopeInfo object on the stack.
    
  - various tests were added - but much more will be needed.

There is obviously more work to be done, and both Richard (weakly) and Doug (strongly) 
have requested that LambdaExpr be removed form the CXXRecordDecl LambdaDefinitionaData
in a future patch which is forthcoming.

A greatful thanks to all reviewers including Eli Friedman, James Dennett, 
and especially the two gracious wizards (Richard Smith and Doug Gregor) 
who spent hours providing feedback (in person in Chicago and on the mailing lists).  
And yet I am certain that I have allowed unidentified bugs to creep in; bugs, that I will do my best to slay, once identified!

Thanks!

Kaelyn Uhrain 95995be7a3 Teach typo correction to look inside of classes like it does namespaces.
Unlike with namespaces, searching inside of classes requires also
checking the access to correction candidates (i.e. don't suggest a
correction to a private class member for a correction occurring outside
that class and its methods or friends).

Included is a small (one line) fix for a bug, that was uncovered while
cleaning up the unit tests, where the decls from a TypoCorrection candidate
were preserved in new TypoCorrection candidates that are derived (copied)
from the old TypoCorrection--notably when creating a new candidate by
changing the NestedNameSpecifier associated with the base idenitifer.
