Richard Trieu 23bafad985 When template deduction fails on a derived class, try a template deduction on
the base class.  If the base class deduction succeeds, use those results.  If
it fails, keep using the results from the derived class template deduction.

This prevents an assertion later where the type of deduction failure doesn't
match up with the template deduction info.

Richard Smith e10d304d20 PR11851 (and duplicates): Whenever a constexpr function is referenced,
instantiate it if it can be instantiated and implicitly define it if it can be
implicitly defined. This matches g++'s approach. Remove some cases from
SemaOverload which were marking functions as referenced when just planning how
overload resolution would proceed; such cases are not actually references.

Douglas Gregor 9194a91dc9 Introduce inferred framework modules into the module map file,
allowing a module map to be placed one level above the '.framework'
directories to specify that all .frameworks within that directory can
be inferred as framework modules. One can also specifically exclude
frameworks known not to work.

This makes explicit (and more restricted) behavior modules have had
"forever", where *any* .framework was assumed to be able to be built
as a module. That's not necessarily true, so we white-list directories
(with exclusions) when those directories have been audited.

Michael Han 64536a6d25 Teach Clang parser to reject C++11 attributes that appertain to declaration specifiers.
We don't support any C++11 attributes that appertain to declaration specifiers so reject 
the attributes in parser until we support them; this also conforms to what g++ 4.8 is doing.

disabling byval, we set realign to true.

It will perform an aligned alloca, and call memcpy to copy the byval

Argyrios Kyrtzidis 2969e124a6 [PCH] Take into account the 'include' source location of a SM_SLOC_BUFFER_ENTRY.
llvm-svn: 167426
2012-11-06 00:35:04 +00:00
Argyrios Kyrtzidis a1c27eb8dd [PCH] Write out the ClassTemplateDecl::Common::InjectedClassNameType type
reference instead of relying on computing it.

In general, if storage is no issue, it is preferable to deserialize info from
the PCH instead of trying to recompute it after the PCH was loaded.

The incentive to change this now was due to r155303 changing how friend template
classes in dependent contexts are handled; such classes can now be chained to
a previous template class but the computed InjectedClassNameType may be different
due to the extra template parameters from the dependent context.

The new handling requires more investigation but, in the meantime, writing out
InjectedClassNameType fixes PCH issue in rdar://12627738.

Douglas Gregor d612566385 Have the parser initialize Sema before it consumes the first
token. This is important because the first token could actually be
after an #include that triggers a module import, which might use
either Sema or the AST consumer before it would have been initialized.

Daniel Dunbar e2951f48bf Frontend: Add support for reading named pipes as the main file.
- The whole {File,Source}Manager is built around wanting to pre-determine the
   size of files, so we can't fit this in naturally. Instead, we handle it like
   we do STDIN, where we just replace the main file contents upfront.

Richard Smith b1b0ab41e7 Use the individual -fsanitize=<...> arguments to control which of the UBSan

Richard Smith 52be619c84 Add -fsanitize=<sanitizers> argument to driver and frontend, and add
-fno-sanitize=<sanitizers> argument to driver. These allow ASan, TSan, and the
various UBSan checks to be enabled and disabled separately. Right now, the
different modes can't be combined, but the intention is that combining UBSan
and the other sanitizers will be permitted in the near future.

Currently, the UBSan checks will all be enabled if any of them is; that will be
fixed by the next patch.

implementation, we'd happily switch to that.
