NAKAMURA Takumi 7174e90078 test/Misc/dev-fd-fs.c: Mark this as XFAIL:freebsd (since r169831).
I don't want to suppress this to be excluded with the feature "dev-fd-fs". This should work also on freebsd.

Eli Friedman cdb135a96b More hacking on mapDiagnosticRanges to make it handle more cases.
This still isn't quite right, but it fixes a crash.

I factored out findCommonParent because we need it on the result of 
getImmediateExpansionRange: for a function macro, the beginning
and end of an expansion range can come out of different
macros/macro arguments, which means the resulting range is a complete
mess to handle consistently.

I also made some changes to how findCommonParent works; it works somewhat
better in some cases, and somewhat worse in others, but I think overall
it's a better balance.  I'm coming to the conclusion that mapDiagnosticRanges
isn't using the right algorithm, though: chasing the caret is fundamentally
more complicated than any algorithm which only considers one FileID for the
caret can handle because each SourceLocation doesn't really have a single parent.
We need to follow the same path of choosing expansion locations and spelling
locations which the caret used to come up with the correct range
in the general case.

Fixes <rdar://problem/12847524>.

Rafael Espindola fc3fc0c936 The clang driver has a fairly fancy support for executing gcc instead of
clang itself. This dates back to clang's early days and while it looks like
some of it is still used (for kext for example), other parts are probably dead.

Remove the -ccc-clang-archs option and associated code. I don't think there
is any remaining setup where clang doesn't support an architecture but it can
expect an working gcc cross compiler to be available.

A nice side effect is that tests no longer need to differentiate architectures
that are included in production builds of clang and those that are not.

Ted Kremenek 9877f689f2 Implement -Wpedantic and --no-pedantic to complement -Weverything.
This patch introduces some magic in tablegen to create a "Pedantic" diagnostic
group which automagically includes all warnings that are extensions.  This
allows a user to suppress specific warnings traditionally under -pedantic used
an ordinary warning flag.  This also allows users to use #pragma to silence
specific -pedantic warnings, or promote them to errors, within blocks of text
(just like any other warning).

-Wpedantic is NOT an alias for -pedantic.  Instead, it provides another way
to (a) activate -pedantic warnings and (b) disable them.  Where they differ
is that -pedantic changes the behavior of the preprocessor slightly, whereas
-Wpedantic does not (it just turns on the warnings).

The magic in the tablegen diagnostic emitter has to do with computing the minimal
set of diagnostic groups and diagnostics that should go into -Wpedantic, as those
diagnostics that already members of groups that themselves are (transitively) members
of -Wpedantic do not need to be included in the Pedantic group directly.  I went
back and forth on whether or not to magically generate this group, and the invariant
was that we always wanted extension warnings to be included in -Wpedantic "some how",
but the bookkeeping would be very onerous to manage by hand.

-no-pedantic (and --no-pedantic) is included for completeness, and matches many of the
same kind of flags the compiler already supports.  It does what it says: cancels out
-pedantic.  One discrepancy is that if one specifies --no-pedantic and -Weverything or
-Wpedantic the pedantic warnings are still enabled (essentially the -W flags win).  We
can debate the correct behavior here.

Along the way, this patch nukes some code in TextDiagnosticPrinter.cpp and CXStoredDiagnostic.cpp
that determine whether to include the "-pedantic" flag in the warning output.  This is
no longer needed, as all extensions now have a -W flag.

This patch also significantly reduces the number of warnings not under flags from 229
to 158 (all extension warnings).  That's a 31% reduction.

Jordan Rose de1a29277e Disable _Pragma during HTML macro rewriting to keep from crashing.
The preprocessor's handling of diagnostic push/pops is stateful, so
encountering pragmas during a re-parse causes problems. HTMLRewrite
already filters out normal # directives including #pragma, so it's
clear it's not expected to be interpreting pragmas in this mode.

This fix adds a flag to Preprocessor to explicitly disable pragmas.
The "right" fix might be to separate pragma lexing from pragma
parsing so that we can throw away pragmas like we do preprocessor
directives, but right now it's important to get the fix in.

Note that this has nothing to do with the "hack" of re-using the
input preprocessor in HTMLRewrite. Even if we someday copy the
preprocessor instead of re-using it, the copy would (and should) include
the diagnostic level tables and have the same problems.

Jordan Rose ccf43ca05c Add pedantic warning -Wempty-translation-unit (C11 6.9p1).
In standard C since C89, a 'translation-unit' is syntactically defined to have
at least one "external-declaration", which is either a decl or a function
definition. In Clang the latter gives us a declaration as well.

The tricky bit about this warning is that our predefines can contain external
declarations (__builtin_va_list and the 128-bit integer types). Therefore our
AST parser now makes sure we have at least one declaration that doesn't come
from the predefines buffer.

Also, remove bogus warning about empty source files. This doesn't catch source
files that only contain comments, and never fired anyway because of our
predefines.

Richard Trieu 2f7dc46a58 Move the warnings for extra semi-colons under -Wextra-semi. Also, added
a warning for an extra semi-colon after function definitions.  Added logic
so that a block of semi-colons on a line will only get one warning instead
of a warning for each semi-colon.

Argyrios Kyrtzidis b16ff5d1ce Fix an assertion hit when the serialized diagnostics writer receive a diagnostic
from the frontend when the location is invalid and the SourceManager null.

Instead of keeping the SourceManager object in DiagnosticRenderer, propagate it
to the calls accordingly (as reference when it is expected to not be null, or pointer
when it may be null).
This effectively makes DiagnosticRenderer not tied to a specific SourceManager,
removing a hack from TextDiagnosticPrinter.

Seth Cantrell 99e2fa87f8 Nicer display of unprintable source, and fix caret display for non-ascii text
Unprintable source in diagnostics is transformed to a printable form and then
displayed with reversed colors if possible. Unprintable characters are
displayed as <U+NNNN> while bytes that do not represent valid characters are
shown as <XX>.

Column adjustments to diagnostic carets, highlighted ranges, and fixups are
made both for characters escaped as above and for characters which are
printable but take up more than a single column.

Richard Smith feea883de4 Implement support for 18 of the GNU-compatible __atomic builtins.
This is not quite sufficient for libstdc++'s <atomic>: we still need
__atomic_test_and_set and __atomic_clear, and may need a more complete
__atomic_is_lock_free implementation.

We are also missing an implementation of __atomic_always_lock_free,
__atomic_nand_fetch, and __atomic_fetch_nand, but those aren't needed
for libstdc++.

Err on the side of brevity and rename (while providing aliases for the original
name) -Wbool-conversions, -Wint-conversions, and -Wvector-conversions for
consistency with constant, literal, string, and sign conversion warnings. And
name the diagnostic groups explicitly while I'm here rather than rewriting the
string in the groups and sema td files.

Curiously, vector-conversion is not under -Wconversion. Perhaps it should be.
