For namespaces, this is consistent with mangling and GCC's debug info
behavior. For structs, GCC uses <anonymous struct> but we prefer
consistency between all anonymous entities but don't want to confuse
them with template arguments, etc, so we'll just go with parens in all
cases.

While investigating some debug info issues, Eric and I came across a
particular template case where the location of a decl was quite
different from the range of the same decl. It might've been rather
helpful if the dumper had actually showed us this.

an out-of-date external decls list). This happens if we declare some names,
force the lookup table for the decl context to be built, import a module that
adds more decls for the name, then write out our module without looking up the
name.

specialization from a module. (This can also happen for function template
specializations in PCHs if they're instantiated eagerly, because they're
constexpr or have a deduced return type.)

at which that PCH imported each visible submodule of the module. Such locations
are needed when synthesizing macro directives resulting from the import.

We were 'allowing' the following import
@import Sub;
where Sub is a subframework of Foo and we had a -F path inside
Foo.framework/Frameworks and no module map file for Sub. This would
later hit assertion failures in debug builds.
Now we should correctly diagnose this as a module not found error.

This name, while more verbose, plays more nicely with tools that use
file extensions to determine file types. The existing spelling
'module.map' will continue to work, but the new spelling will take
precedence.
In frameworks, this new filename will only go in a new 'Modules'
sub-directory.
Similarly, add a module.private.modulemap corresponding to
module_private.map.
llvm-svn: 204261
The spelling location of stringified strings is not a file location.
Optimally, we'll want to solve the problem (as the FIXME states) by
handing in the right FileEntry of the #include location.

Test doesn't actually require production of an object file and for
some targets (e.g. hexagon) an assembler is not always available when
lit tests are run.
llvm-svn: 204144
This is because the PCH is tied to the module files, if one of the module files changes or gets removed
the build system should re-build the PCH file.

When enabled, always validate the system headers when loading a module.
The end result of this is that when these headers change, we will notice
and rebuild the module.

to absolute paths when building the includes file for the module. Without this,
the module build would fail, because the relative paths we were using are not
necessarily relative to a directory in our include path.

if the type's declaration was previously instantiated in an unimported module.
(For an imported type definition, this already worked, because the source
location is set to the location of the definition, but for locally-instantiated
type definitions, it did not.)

Add module dependencies to the dependency files created by -MD/-MMD/etc.

file generator when a module input file is seen in the serialized AST.

submodule macro overriding within the same top-level module (necessary for the
testcase to be remotely reasonable). Incidentally reduces the number of libc++
testsuite regressions with modules enabled from 7 to 6.

it, importers of B should not see the macro. This is complicated by the fact
that A's macro could also be visible through a different path. The rules (as
hashed out on cfe-commits) are included as a documentation update in this
change.
With this, the number of regressions in libc++'s testsuite when modules are
enabled drops from 47 to 7. Those remaining 7 are also macro-related, and are
due to remaining bugs in this change (in particular, the handling of submodules
is imperfect).

For some reason we have two bits of code handling this printing:
lib/AST/Decl.cpp: OS << "<anonymous namespace>";
lib/AST/TypePrinter.cpp: OS << "<anonymous namespace>::";
it would be nice if we only had one...

This commit improves libclang to report the error condition when
CXTranslationUnit can not be created because of a stale PCH file. This allows
the caller, for example, to rebuild the PCH file and retry the request.
There two are APIs in libclang that return a CXTranslationUnit and don't
support reporting detailed errors (the only error condition is a NULL result).
For these APIs, a second, superior, version is introduced --
clang_createTranslationUnit2 and clang_parseTranslationUnit2. These functions
return a CXTranslationUnit indirectly and also return an error code. Old
functions are still supported and are nothing more than convenience wrappers
that ignore extended error codes.
As a cleanup, this commit also categorizes some libclang errors in the
functions I had to modify anyway.

using-declaration, and they declare the same function (either because
the using-declaration is in the same namespace as the declaration it
imports, or because they're both extern "C"), they do not conflict.

Add the ImportDecl to the set of interesting delcarations that are
deserialized eagerly when an AST file is loaded (rather than lazily like
most decls). This is required to get auto linking to work when there is
no explicit import in the main file. Also resolve a FIXME to rename
'ExternalDefinitions', since that is only one of the things that need eager
deserialization. The new name is 'EagerlyDeserializedDecls'. The corresponding
AST bitcode is also renamed.

Removes some old code that allowed a module to be loaded from a pcm file
even if the module.map could not be found. Also update a number of
tests that relied on the old behavior.

This makes the C++ ABI depend entirely on the target: MS ABI for -win32 triples,
Itanium otherwise. It's no longer possible to do weird combinations.
To be able to run a test with a specific ABI without constraining it to a
specific triple, new substitutions are added to lit: %itanium_abi_triple and
%ms_abi_triple can be used to get the current target triple adjusted to the
desired ABI. For example, if the test suite is running with the i686-pc-win32
target, %itanium_abi_triple will expand to i686-pc-mingw32.

If a header file belonging to a certain module is not found on the
filesystem, that header gets marked as unavailable. Now, the layering
warning (-fmodules-decluse) should still warn about headers of this
module being wrongfully included. Currently, headers belonging to those
modules are just treated as not belonging to modules at all which means
they can be included freely from everywhere.
To implement this (somewhat) cleanly, I have moved most of the layering
checks into the ModuleMap. This will also help with showing FixIts
later.
llvm-svn: 197805
Instead, mark the module as unavailable so that clang errors as soon as
someone tries to build this module.
This works towards the long-term goal of not stat'ing the header files at all
while reading the module map and instead read them only when the module is
being built (there is a corresponding FIXME in parseHeaderDecl()). However, it
seems non-trivial to get there and this unblock us and moves us into the right
direction.
Also changed the implementation to reuse the same DiagnosticsEngine.
