Yaron Keren 09fb7c6e7a Teach raw_ostream to accept SmallString.
Saves adding .str() call to any raw_ostream << SmallString usage
and a small step towards making .str() consistent in the ADTs by
removing one of the SmallString::str() use cases, discussion at

http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20141013/240026.html

I'll update the Phabricator patch http://reviews.llvm.org/D6372
for review of the Twine SmallString support, it's more complex
than this one.

Richard Smith 2708e52029 [modules] This check is run before we resolve the header, not after, so just
check that private headers are in a list matching the role. (We can't perform
the opposite checks for non-private headers because we infer those.)

Ben Langmuir 1f6a32b3e7 Don't load Framework module.map files when searching subdirectories
This would cause frameworks to have spurious "redefinition" errors if
they had both a (legacy) "module.map" and a (new) "module.modulemap" file and we
happened to do a sub-directory search in that directory using a
non-framework include path (e.g. -Ifoo/ -Ffoo/).  For migration
purposes it's very handy that the compiler will prefer the new spelling
of the filename and not look at the old one if it doesn't need to.

Ben Langmuir 18dd78a8fd Mangle the IsSystem bit into the .pcm file name
When mangling the module map path into a .pcm file name, also mangle the
IsSystem bit, which can also depend on the header search paths. For
example, the user may change from -I to -isystem.  This can affect
diagnostics in the importing TU.

Serge Pavlov 07c0f04e08 Fixed warnings on redefine keywords and reserved ids.
Repared support for warnings -Wkeyword-macro and -Wreserved-id-macro.
The warning -Wkeyword-macro now is not issued in patterns that are used
in configuration scripts:

    #define inline

also for 'const', 'extern' and 'static'. If macro repalcement is identical
to macro name, the warning also is not issued:

    #define volatile volatile

And finally if macro replacement is also a keyword identical to the replaced
one but decorated with leading/trailing underscores:

    #define inline __inline
    #define inline __inline__
    #define inline _inline // in MSVC compatibility mode

Warning -Wreserved-id-macro is off by default, it could help catching
things like:

    #undef __cplusplus

Nico Weber 92c14bb2ff Move -Wkeyword-macro into -pedantic, remove -Wreserved-id-macro.
As discussed on the post-commit review thread for r224012, -Wkeyword-macro fires
mostly on headers trying to set up portable defines and doesn't find much bad
stuff in practice.  But [macro.names]p2 does disallow defining or undefining
keywords, override and final, and alignas, so keep the warning but move it
into -pedantic.

-Wreserved-id-macro warns on

    #define __need_size_t

which is more or less public api for glibc headers. Since this warning isn't
motivated by a standard, remove it.

(See also r223114 for a previous follow-up to r224012.)

Richard Smith 9acb99e342 Reinstate r223753, reverted in r223759 due to breakage of clang-tools-extra.
Original commit message:

[modules] Add experimental -fmodule-map-file-home-is-cwd flag to -cc1.

For files named by -fmodule-map-file=, and files found by 'extern module'
directives, this flag specifies that we should resolve filenames relative to
the current working directory rather than relative to the directory in which
the module map file resides. This is aimed at fixing path handling, in
particular for relative -I paths, when building modules that represent
components of the current project (rather than libraries installed on the
current system, which the current project has as dependencies, where we'd
typically expect the module map files to be looked up implicitly).

Sean Callanan 8759649013 Modified the Objective-C lexer and parser (only
in debugger mode) to accept @import declarations
and pass them to the debugger.  

In the preprocessor, accept import declarations
if the debugger is enabled, but don't actually
load the module, just pass the import path on to 
the preprocessor callbacks.

In the Objective-C parser, if it sees an import
declaration in statement context (usual for LLDB),
ignore it and return a NullStmt.

but I'm not the right one to look into it.

Aaron Ballman a6f759e423 Modify __has_attribute so that it only looks for GNU-style attributes. Removes the ability to look for generic attributes and keywords via this macro, which has the potential to be a breaking change. However, since there is __has_cpp_attribute and __has_declspec_attribute, and given the limited usefulness of querying a generic attribute name regardless of syntax, this seems like the correct path forward.

Serge Pavlov 1ecb41c09b Emit warning if define or undef reserved identifier or keyword.
Summary:
This change implements warnings if macro name is identical to a keyword or
reserved identifier. The warnings are different depending on the "danger"
of the operation. Defining macro that replaces a keyword is on by default.
Other cases produce warning that is off by default but can be turned on
using option -Wreserved-id-macro.

This change fixes PR11488.

Richard Smith 3c1a41ad99 [modules] Track how 'header' directives were written in module map files,
rather than trying to extract this information from the FileEntry after the
fact.

This has a number of beneficial effects. For instance, diagnostic messages for
failed module builds give a path relative to the "module root" rather than an
absolute file path, and the contents of the module includes file is no longer
dependent on what files the including TU happened to inspect prior to
triggering the module build.
