Daniel Jasper d8c36d09b1 Make clang-format slightly more willing to break before trailing annotations.
Specifically, prefer breaking before trailing annotations over breaking
before the first parameter.

Before:
  void ffffffffffffffffffffffff(
      int aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa,
      int aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa) OVERRIDE;

After:
  void ffffffffffffffffffffffff(int aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa,

      OVERRIDE;

Richard Smith 3d8e97eda2 C++ modules: don't lose track of a 'namespace std' that is imported from a module.
llvm-svn: 192951
2013-10-18 06:54:39 +00:00
Richard Smith 2b9e3e396a Basic ODR checking for C++ modules:
If we have multiple definitions of the same entity from different modules, we
nominate the first definition which we see as being the canonical definition.
If we load a declaration from a different definition and we can't find a
corresponding declaration in the canonical definition, issue a diagnostic.

This is insufficient to prevent things from going horribly wrong in all cases
-- we might be in the middle of emitting IR for a function when we trigger some
deserialization and discover that it refers to an incoherent piece of the AST,
by which point it's probably too late to bail out -- but we'll at least produce
a diagnostic.

Alp Toker 19bff32e09 Check "late parsed" friend functions for redefinition
r177003 applied the late parsed template technique to friend functions
but omitted the corresponding check for redefinitions.

This patch adds the same check already in use for templates to the
new code path in order to diagnose and reject invalid redefinitions
that were being silently accepted.

Fixes PR17324.

Alp Toker ae3a944a6e Fix missed exception spec checks and crashes
Delayed exception specification checking for defaulted members and virtual
destructors are both susceptible to mutation during iteration so we need to
swap and process the worklists.

This resolves both accepts-invalid and rejects-valid issues and moreover fixes
potential invalid memory access as the contents of the vectors change during
iteration and recursive template instantiation.

Checking can be further delayed where parent classes aren't yet fully defined.
This patch adds two assertions at end of TU to ensure no specs are left
unchecked as was happenning before the fix, plus a test case from Marshall Clow
for the defaulted member crash extracted from the libcxx headers.

This removes the dependency on the llvm mangler doing it for us. In isolation,
the benefit is that the testing of what mangling is applied is all in one place:

Reid Kleckner 916ac4d233 ms-compat: Fix taking the address of a member of a dependent base
If unqualified id lookup fails while parsing a class template with a
dependent base, clang with -fms-compatibility will pretend the user
prefixed the name with 'this->' in order to delay the lookup.  However,
if there was a unary ampersand, Sema::ActOnDependentIdExpression() will
create a DependentDeclRefExpr, which is not what we wanted at all.  Fix
this by building the CXXDependentScopeMemberExpr directly instead.

In order to be fully MSVC compatible, we would have to defer all
attempts at name lookup to instantiation time.  However, until we have
real problems with system headers that can't be parsed, we'll put off
implementing that.

Fixes PR16014.

Serge Pavlov c0cd80fb20 Do not use typo correction that is unaccessible.
This patch fixes PR17019. When doing typo correction, Sema::CorrectTypo uses
correction already seen for the same typo. This causes problems if that
correction is from another scope and cannot be accessed in the current.

Ismail Pazarbasi 8d0f2f3ae3 Relax header guard mismatch warning with edit distance heuristic.
If the edit distance between the two macros is more than 50%, DefinedMacro may not be header guard or can be header guard of another header file or it might be defining something completely different set by the build environment.

Manuel Klimek b212f3baa1 Automatically munch semicolons after blocks.
While it is mostly a user error to have the extra semicolon,
formatting it graciously will correctly format in the cases
where we do not fully understand the code (macros).

Richard Trieu 0825469126 Improve the error message for attempting to build a for range loop using a
function parameter that has array type.  Such a parameter will be treated as
a pointer type instead, resulting in a missing begin function error is a
suggestion to dereference the pointer.  This provides a different,
more informative diagnostic as well as point to the parameter declaration.

Alexander Kornienko 384b40b90d Don't break string literals inside preprocessor directives.
Summary:
This way we avoid breaking code which uses unknown preprocessor
directives with long string literals. The specific use case in
http://llvm.org/PR17035 isn't very common, but it seems to be a good idea to
avoid this kind of problem anyway.
