Francois Ferrand 5f07f443be clang-format: Fix C99 designated initializers corner cases
Summary:
This fixes the missing space before the designated initializer when `Cpp11BracedListStyle=false` :

  const struct A a = { .a = 1, .b = 2 };
                      ^

Also, wrapping between opening brace and designated array initializers used to have an excessive penalty (like breaking between an expression and the subscript operator), leading to unexpected wrapping:

  const struct Aaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaa =
      {[1] = aaaaaaaaaaaaaaaaaaaaaaaaaaa,
       [2] = bbbbbbbbbbbbbbbbbbbbbbbbbbb};

instead of:

  const struct Aaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaa = {
      [1] = aaaaaaaaaaaaaaaaaaaaaaaaaaa,
      [2] = bbbbbbbbbbbbbbbbbbbbbbbbbbb};

Finally, designated array initializers are not binpacked, just like designated member initializers.

Christof Douma f9d86db755 [NFC] Refactor DiagnosticRenderer to use FullSourceLoc
Move the DiagnosticRenderer and its dependents to using FullSourceLocs
instead of a SourceLocation and SourceManager pointer. The changeset is
rather large but entirely mechanical.

This is step one to allow DiagnosticRenderer to take either
llvm::SMLocs or clang::SourceLocations.

With this patch, one can configure a BufWrite hook that will make the
clang-format integration compute a diff of the current buffer with the file
that's on disk and format all changed lines. This should create a
zero-overhead auto-format solution that doesn't require the file to
already be clang-format clean to avoid spurious diffs.

Lang Hames 8ca265f4a1 Call setMustBuildLookupTable on TagDecls in ExternalASTMerger
Summary:
setMustBuildLookupTable should be called on imported TagDecls otherwise we may fail
to import their member decls (if they have any).

Not calling the setMustBuildLookupTable method results in a failure in the attached test
case when lookup for the 'x' member fails on struct S, which hasn't had its decls imported
elsewhere. (By contrast the member-in-struct testcase hasn't run into this issue
because the import of its decls is triggered when the struct instance is defined, and the
member access follows this).

it into the combined regular LTO module right away, add it to the

represents the combined regular LTO module.

Any such modules are linked during LTO::run(), at which time we use
the results of summary-based dead stripping to control whether to
link prevailing symbols.

Erich Keane 8691d6e678 [Preprocessor]Correct Macro-Arg allocation of StringifiedArguments,
correct getNumArguments

StringifiedArguments is allocated (resized) based on the size the 
getNumArguments function. However, this function ACTUALLY currently 
returns the amount of total UnexpArgTokens which is minimum the same as 
the new implementation of getNumMacroArguments, since empty/omitted arguments 
result in 1 UnexpArgToken, and included ones at minimum include 2 
(1 for the arg itself, 1 for eof).

This patch renames the otherwise unused getNumArguments to be more clear 
that it is the number of arguments that the Macro expects, and thus the maximum 
number that can be stringified. This patch also replaces the explicit memset 
(which results in value instantiation of the new tokens, PLUS clearing the 
memory) with brace initialization.

llvm-svn: 305381
2017-06-14 10:57:56 +00:00
Serge Pavlov c73c81be5c Function with unparsed body is a definition
While a function body is being parsed, the function declaration is not considered
as a definition because it does not have a body yet. In some cases it leads to
incorrect interpretation, the case is presented in
https://bugs.llvm.org/show_bug.cgi?id=14785:
```
    template<typename T> struct Somewhat {
      void internal() const {}
      friend void operator+(int const &, Somewhat<T> const &) {}
    };
void operator+(int const &, Somewhat<char> const &x) { x.internal(); }
```
When statement `x.internal()` in the body of global `operator+` is parsed, the type
of `x` must be completed, so the instantiation of `Somewhat<char>` is started. It
instantiates the declaration of `operator+` defined inline, and makes a check for
redefinition. The check does not detect another definition because the declaration
of `operator+` is still not defining as does not have a body yet.

To solves this problem the function `isThisDeclarationADefinition` considers
a function declaration as a definition if it has flag `WillHaveBody` set.

This change fixes PR14785.
