I'm not sure now how this should be fixed. %lld is non-standard
and not accepted by mingw on Windows while PRId64 is bad for this bot.
Is long long longer than 64 bits here? if not, why is PRId64
incompatible with it? something seems wrong.
Probably all the datatypes should be replaced to unsigned or uint64_t
depending upin requirements instead of the non standard long long.

This, in preparation for the introduction of more new keywords in the
implementation of the C++ language, generalizes the support for future keyword
compat diagnostics (e.g., diag::warn_cxx11_keyword) by extending the
applicability of the relevant property in IdentifierTable with appropriate
renaming.

xmmintrin.h includes emmintrin.h and vice versa if SSE2 is enabled. We break
this cycle for a modules build, and instead make the xmmintrin.h module
re-export the immintrin.h module. Also included is a fix for an assert in the
serialization code if a module exports another module that was declared later
in the same module map.

Backslash followed by # in a filename should have both characters
escaped, if you do it the way GNU Make wants. GCC doesn't, so we do
it the way GCC does rather than the way GNU Make wants.

Previously we were setting LangOptions::GNUInline (which controls whether we
use traditional GNU inline semantics) if the language did not have the C99
feature flag set. The trouble with this is that C++ family languages also
do not have that flag set, so we ended up setting this flag in C++ modes
(and working around it in a few places downstream by also checking CPlusPlus).
The fix is to check whether the C89 flag is set for the target language,
rather than whether the C99 flag is cleared. This also lets us remove most
CPlusPlus checks. We continue to test CPlusPlus when deciding whether to
pre-define the __GNUC_GNU_INLINE__ macro for consistency with GCC.
There is a change in semantics in two other places
where we weren't checking both CPlusPlus and GNUInline
(FunctionDecl::doesDeclarationForceExternallyVisibleDefinition and
FunctionDecl::isInlineDefinitionExternallyVisible), but this change seems to
put us back into line with GCC's semantics (test case: test/CodeGen/inline.c).
While at it, forbid -fgnu89-inline in C++ modes, as GCC doesn't support it,
it didn't have any effect before, and supporting it just makes things more
complicated.

When writing a dependency (.d) file, if space or # is immediately
preceded by one or more backslashes, escape the backslashes as well as
the space or # character. Otherwise leave backslash alone.
This straddles the fence between BSD Make (which does no escaping at
all, and does not support space or # in filespecs) and GNU Make (which
does support escaping, but will fall back to the filespec as-written
if the escaping doesn't match an existing file).

before binary/ternary operators.
Basically, it doesn't seem right to indent a nested block aligned to a
binary or ternary operator.
Before:
int i = aaaaaa ? 1 //

return 2; //
}();
llvm::errs() << "number of twos is "
<< std::count_if(v.begin(), v.end(), [](int x) {
return x == 2; // force break

Previously, if a semi-colon is unexpectedly added before a closing ')', ']' or
'}', two errors and one note would emitted, and the parsing would get confused
to which scope it was in. This change consumes the semi-colon, recovers
parsing better, and emits only one error with a fix-it.

GetOutputStream() owns the stream it returns pointer to and the
pointer should never be freed by us. When we fail to load and exit
early, unique_ptr still holds the pointer and frees it which leads to
compiler crash when CompilerInstance attempts to free it again.
Added regression test for failed bitcode linking.

sys/time.h on Solaris (and possibly other systems) defines "SEC" as "1"

Fixes https://llvm.org/PR23482
llvm-svn: 237113
Summary:
a) Pull out a class LevelIndentTracker whose responsibility is to keep track
of the indent of levels across multiple annotated lines.
b) Put all responsibility for merging lines into the LineJoiner; make the
LineJoiner iterate over the lines so we never operate on a line that might
be merged later; this makes the interface safer to use.
c) Move formatting of the end-of-file whitespace into formatFirstToken.
Fix bugs that became obvious after the refactoring:
1. We would not format lines with offsets correctly inside nested blocks if
only the outer expression was affected:
int x = s({ // clang-format only this line
class X {
public:
// ^ this starts at the non-modified indnent level; previously we would
// not fix this, now we correctly outdent it.
void f();
};
});
2. We would incorrectly align comments across lines that do not have comments
for lines with nested blocks:
int expression; // with comment
int x = s({
int y; // comment
int z; // we would incorrectly align this comment with the comment on
// 'expression'
});

'schedule' clause for combined directives requires additional processing. Special helper variable is generated, that is captured in the outlined parallel region for 'parallel for' region. This captured variable is used to store chunk expression from the 'schedule' clause in this 'parallel for' region.

The MachO toolchain has an isTargetIOSBased method, but it isn't
virtual so it isn't very meaningful to call it. After thinking about
this, I guess that putting this logic in the MachO class is a bit of a
layering violation anyway. Do this more like how we handle
AddLinkRuntimeLibArgs instead.
llvm-svn: 237095
Compiler-rt's Profiling library isn't part of the stdlib, so -nostdlib
shouldn't prevent it from being linked. This makes Darwin behave like
other toolchains, and link in the profile runtime irrespective of
-nostdlib, since the resulting program can't be run unless you link
this.
I've also added a test to show that other toolchains already behave
like this.

Empty assembly string will not introduce assembly code in the output
binary and it is often used as a trick in the header to disable
optimizations. It doesn't conflict with the purpose of the option so it
is allowed with -fno-gnu-inline-asm flag.

This is necessary in order to allow the use of a constexpr member function, or

Summary:
AsmLabel is heavily used in system level and firmware to redirect
function and access platform specific labels. They are also extensively
used in system headers which makes this option unusable for many
users. Since AsmLabel doesn't introduce any assembly code into the
output binary, it shouldn't be considered as inline-asm.

Pull various parts of the UnwrappedLineFormatter into their own

We didn't supporting taking the address of virtual member functions
which overrode a method in a virtual base. We simply need to encode the
virtual base index in the member pointer.
This fixes PR23452.
N.B. There is no data member pointer side to this change because taking
the address of a virtual bases' data member gives you a member pointer
whose type is derived from the virtual bases' type, not the most derived
type.

MSVC 2015 renamed the symbol found by name lookup for 'std::terminate'
so we cannot rely on using '?terminate@@YAXXZ'. Furthermore, it seems
that 2015 will be the first release of MSVC which permits inlining a
function which is noexcept into a function which isn't. This is
implemented by creating a cleanup for the invoker which jumps to
__std_terminate. Clang's implementation of this aspect of the MSVC
scheme is slightly less efficient in this respect because we use a
catch handler configured as a catch-all handler instead.

This reverts commit 236854, which caused clang-format to always print
'{ "IncompleteFormat": false }' at the top of an incompletely formatted file.
This output causes problems e.g. in Polly's automatic formatting checks. Daniel
tried to fix this in 236867, but this fix had to be reverted due to buildbot
failures. I revert this change as well for now as it is Friday night and
unlikely to be fixed immediately.

This is a starting point for using the TargetParser in Clang, in a simple
enough part of the code that can be used without disrupting the crazy
platform support that we need to be compatible with other toolchains.
Also adding a few FIXME on obvious places that need replacing, but those
cases will indeed break a few of the platform assumptions, as arch/cpu names
change multiple times in the driver.
Finally, I'm changing the "neon-vfpv3" behaviour to match standard NEON, since
-mfpu=neon implies vfpv3 by default in both Clang and LLVM. That option
string is still supported as an alias to "neon".

In particular:
* If the difference between the longest and shortest element, we copped
out of column format completely. Now, we instead allow to arrange
these in a single column, essentially enforcing a one-per-line format.
* Allow column layout even if there are braced lists. Especially, if
there are many short lists, this can be beneficial. The bad case,
where there is a long nested init list is usually caught as we now
limit the length difference of the longest and shortest element.
