Tim Northover 157d911b42 MachO: use *-*-*-macho for MachO embedded targets.
Previously we had bodged together some hacks mapping MachO embedded
targets (i.e. mainly ARM v6M and v7M) to the "*-*-darwin-eabi" triple.
This is incorrect in both details (they don't run Darwin and they're
not EABI in any real sense).

This commit appropriates the existing "MachO" environment for the
purpose instead.

Chandler Carruth b653131345 Move a bunch of tests to directly use the CC1 layer. This at least saves
a subprocess invocation which is pretty significant on Windows. It also
likely saves a bunch of thrashing the host machine needlessly. Finally
it makes the tests much more predictable and less dependent on the host.
For example 'header_lookup1.c' was passing '-fno-ms-extensions' just to
thwart the host detection adding it into the compilation. By runnig CC1
directly we don't have to deal with such oddities.

Ana Pazos dd6068d400 Added support for mcpu krait
- krait processor currently modeled with the same features as A9.
- Krait processor additionally has VFP4 (fused multiply add/sub)
and hardware division features enabled.
- krait has currently the same Schedule model as A9
- krait cpu flag is not recognized by the GNU assembler yet,
it is replaced with march=armv7-a to avoid a lower march
from being used.

David Majnemer 76faf1f525 Lex: Require that '#' be followed by a macro parameter name when preceded by '##'
After lexing a '##', we would look ahead and check to see if it was
followed by '__VA_ARGS__'.  After doing so, we would then go ahead and
lex the token.

However we would fail in the case where the '##' was followed by a '#'
followed by an identifier because we would have lexed the '#' separately
from the identifier, bypassing our parameter validation logic.

Instead, lex the tokens coming after the '##' later.

This fixes PR17804.

Justin Bogner 5353513058 Lex: Don't restrict legal UCNs when preprocessing assembly
The C and C++ standards disallow using universal character names to
refer to some characters, such as basic ascii and control characters,
so we reject these sequences in the lexer. However, when the
preprocessor isn't being used on C or C++, it doesn't make sense to
apply these restrictions.

Notably, accepting these characters avoids issues with unicode escapes
when GHC uses the compiler as a preprocessor on haskell sources.

Ed Schouten d062146896 Add character set related __STDC_* definitions.
Clang uses UTF-16 and UTF-32 for its char16_t's and char32_t's
exclusively. This means that we can define __STDC_UTF_16__ and
__STDC_UTF_32__ unconditionally.

While there, define __STDC_MB_MIGHT_NEQ_WC__ for FreeBSD. FreeBSD's
wchar_t's don't encode characters as ISO-10646; the encoding depends on
the locale used. Because the character set used might not be a superset
of ASCII, we must define __STDC_MB_MIGHT_NEQ_WC__.

Eli Friedman 0834a4b901 Make Preprocessor::Lex non-recursive.
Before this patch, Lex() would recurse whenever the current lexer changed (e.g.
upon entry into a macro). This patch turns the recursion into a loop: the
various lex routines now don't return a token when the current lexer changes,
and at the top level Preprocessor::Lex() now loops until it finds a token.
Normally, the recursion wouldn't end up being very deep, but the recursion depth
can explode in edge cases like a bunch of consecutive macros which expand to
nothing (like in the testcase test/Preprocessor/macro_expand_empty.c in this
patch).

Hal Finkel c4d7c82c7f Add the intrinsic __builtin_convertvector
LLVM supports applying conversion instructions to vectors of the same number of
elements (fptrunc, fptosi, etc.) but there had been no way for a Clang user to
cause such instructions to be generated when using builtin vector types.

C-style casting on vectors is already defined in terms of bitcasts, and so
cannot be used for these conversions as well (without leading to a very
confusing set of semantics). As a result, this adds a __builtin_convertvector
intrinsic (patterned after the OpenCL __builtin_astype intrinsic). This is
intended to aid the creation of vector intrinsic headers that create generic IR
instead of target-dependent intrinsics (in other words, this is a generic
_mm_cvtepi32_ps). As noted in the documentation, the action of
__builtin_convertvector is defined in terms of the action of a C-style cast on
each vector element.

Bill Schmidt 778d387684 [PowerPC] Support powerpc64le as a syntax-checking target.
This patch provides basic support for powerpc64le as an LLVM target.
However, use of this target will not actually generate little-endian
code.  Instead, use of the target will cause the correct little-endian
built-in defines to be generated, so that code that tests for
__LITTLE_ENDIAN__, for example, will be correctly parsed for
syntax-only testing.  Code generation will otherwise be the same as
powerpc64 (big-endian), for now.

The patch leaves open the possibility of creating a little-endian
PowerPC64 back end, but there is no immediate intent to create such a
thing.

The new test case variant ensures that correct built-in defines for
little-endian code are generated.

This allows clang to parse the type_traits header in Visual Studio 2012,
which is included widely in practice.

This is a rework of r163022 by João Matos.  The original patch broke
preprocessing of gtest headers, which this patch addresses.

Jordan Rose 67b66231a8 Preprocessor: don't keep comments under -traditional-cpp.
This patch is designed for minimal intrusion into normal preprocessing

generate tok::comment nodes since it is preserving all whitespace, but
the output printer will then throw it away.

Jordan Rose 864b810739 Preprocessor: don't consider // to be a line comment in -E -std=c89 mode.
It's beneficial when compiling to treat // as the start of a line
comment even in -std=c89 mode, since it's not valid C code (with a few
rare exceptions) and is usually intended as such. We emit a pedantic
warning and then continue on as if line comments were enabled.
This has been our behavior for quite some time.

However, people use the preprocessor for things besides C source files.
In today's prompting example, the input contains (unquoted) URLs, which
contain // but should still be preserved.

This change instructs the lexer to treat // as a plain token if Clang is
in C90 mode and generating preprocessed output rather than actually compiling.

Jordan Rose 7f43dddae0 Handle universal character names and Unicode characters outside of literals.
This is a missing piece for C99 conformance.

This patch handles UCNs by adding a '\\' case to LexTokenInternal and
LexIdentifier -- if we see a backslash, we tentatively try to read in a UCN.
If the UCN is not syntactically well-formed, we fall back to the old
treatment: a backslash followed by an identifier beginning with 'u' (or 'U').

Because the spelling of an identifier with UCNs still has the UCN in it, we
need to convert that to UTF-8 in Preprocessor::LookUpIdentifierInfo.

Of course, valid code that does *not* use UCNs will see only a very minimal
performance hit (checks after each identifier for non-ASCII characters,
checks when converting raw_identifiers to identifiers that they do not
contain UCNs, and checks when getting the spelling of an identifier that it
does not contain a UCN).

This patch also adds basic support for actual UTF-8 in the source. This is
treated almost exactly the same as UCNs except that we consider stray
Unicode characters to be mistakes and offer a fixit to remove them.

Matt Beaumont-Gay 978cca9f49 Suppress all -Wunused-value warnings from macro body expansions.
This is inspired by a number of false positives in real code, including
PR14968. I've added test cases reduced from these false positives to
test/Sema/unused-expr.c, as well as corresponding test cases that pass the
offending expressions as arguments to a no-op macro to ensure that we do warn
there.

This also removes my previous tweak from r166522/r166534, so that we warn on
unused cast expressions in macro arguments.

There were several test cases that were using -Wunused-value to test general
diagnostic emission features; I changed those to use other warnings or warn on
a macro argument expression. I stared at the test case for PR14399 for a while
with Richard Smith and we believe the new test case exercises the same
codepaths as before.

Andy Gibbs 58905d251b Refactored duplicate string literal lexing code within Preprocessor, into a

with macro expansion, but subsequent ones were not) and also an erroneous
diagnostic has been corrected.

Eli Friedman 14d3c79b45 Suppress elided variadic macro argument extension diagnostic for macros using
the related comma pasting extension.

In certain cases, we used to get two diagnostics for what is essentially one
extension.  This change suppresses the first diagnostic in certain cases
where we know we're going to print the second diagnostic.  The
diagnostic is redundant, and it can't be suppressed in the definition
of the macro because it points at the use of the macro, so we want to
avoid printing it if possible.

The implementation works by detecting constructs which look like comma
pasting at the time of the definition of the macro; this information
is then used when the macro is used.  (We can't actually detect
whether we're using the comma pasting extension until the macro is
actually used, but we can detecting constructs which will be comma
pasting if the varargs argument is elided.)

Instead of adding it to each individual subclass in

Where before it was only on x86_64 and ppc64, it's now

Dylan Noblesmith 673728fe57 Preprocessor: add __BYTE_ORDER__ predefined macro
The __BYTE_ORDER__ predefined macro was added in GCC 4.6:
http://gcc.gnu.org/onlinedocs/gcc-4.6.0/cpp/Common-Predefined-Macros.html

It's used like the following:

 #if __BYTE_ORDER__ == __ORDER_LITTLE_ENDIAN__
 ...
 #elif __BYTE_ORDER__ == __ORDER_BIG_ENDIAN__
 ...
 #else
 #error insane architecture like the pdp-11
 #endif

There's a similar macro, __FLOAT_WORD_ORDER__, but it looks like it
mainly exist to accommodate fairly obscure architectures and ARM's
old FPA instructions, so it doesn't seem nearly as useful.

The tests are updated to check for the correct(at least, based on
clang's current output) value of the macro on each target. So now the
suite will catch bugs like the one fixed in r157626.

Jordan Rose b13eb8dca5 Allow -verify directives to be filtered by preprocessing.
This is accomplished by making VerifyDiagnosticsConsumer a CommentHandler,
which then only reads the -verify directives that are actually in live
blocks of code. It also makes it simpler to handle -verify directives that
appear in header files, though we still have to manually reparse some files
depending on how they are generated.

This requires some test changes. In particular, all PCH tests now have their
-verify directives outside the "header" portion of the file, using the @line
syntax added in r159978. Other tests have been modified mostly to make it
clear what is being tested, and to prevent polluting the expected output with
the directives themselves.

John McCall 5fb5df9c83 Restructure how the driver communicates information about the
target Objective-C runtime down to the frontend:  break this
down into a single target runtime kind and version, and compute
all the relevant information from that.  This makes it
relatively painless to add support for new runtimes to the
compiler.  Make the new -cc1 flag, -fobjc-runtime=blah-x.y.z,
available at the driver level as a better and more general
alternative to -fgnu-runtime and -fnext-runtime.  This new
concept of an Objective-C runtime also encompasses what we
were previously separating out as the "Objective-C ABI", so
fragile vs. non-fragile runtimes are now really modelled as
different kinds of runtime, paving the way for better overall
differentiation.

As a sort of special case, continue to accept the -cc1 flag
-fobjc-runtime-has-weak, as a sop to PLCompatibilityWeak.

I won't go so far as to say "no functionality change", even
ignoring the new driver flag, but subtle changes in driver
semantics are almost certainly not intended.

This functionality is based on what is done on ARM, and enables selecting PPC CPUs
in a way compatible with gcc's driver. Also, mirroring gcc (and what is done on x86),
-mcpu=native support was added. This uses the host cpu detection from LLVM
(which will also soon be updated by refactoring code currently in backend).

In order for this to work, the target needs a list of valid CPUs -- we now accept all CPUs accepted by LLVM.

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.

actually verifying as intended.

I'd like to change the driver so this kind of mistake could not be made, but

flags in general, we could have similar bugs with a misspellings of arguments

Chandler Carruth c0c0455f55 Teach Clang about PIE compilations. This is the first step of PR12380.
First, this patch cleans up the parsing of the PIC and PIE family of
options in the driver. The existing logic failed to claim arguments all
over the place resulting in kludges that marked the options as unused.
Instead actually walk all of the arguments and claim them properly.

We now treat -f{,no-}{pic,PIC,pie,PIE} as a single set, accepting the
last one on the commandline. Previously there were lots of ordering bugs
that could creep in due to the nature of the parsing. Let me know if
folks would like weird things such as "-fPIE -fno-pic" to turn on PIE,
but disable full PIC. This doesn't make any sense to me, but we could in
theory support it.

Options that seem to have intentional "trump" status (-static, -mkernel,
etc) continue to do so and are commented as such.

Next, a -pie-level flag is threaded into the frontend, rigged to
a language option, and handled preprocessor, setting up the appropriate
defines. We'll now have the correct defines when compiling with -fpie.

The one place outside of the preprocessor that was inspecting the PIC
level (as opposed to the relocation model, which is set and handled
separately, yay!) is in the GNU ObjC runtime. I changed it to exactly
preserve existing behavior. If folks want to change its behavior in the
face of PIE, they can do that in a separate patch.

Essentially the only functionality changed here is the preprocessor
defines and bug-fixes to the argument management.

Tests have been updated and extended to test all of this a bit more
thoroughly.

This ensures that we will activate it in the correct location
or that we will ignore it if it never enters the token stream, e.g:

Argyrios Kyrtzidis a956450eb7 [preprocessor] Handle correctly inclusion directives that have macro expansions, e.g
"#include MACRO(STUFF)".

-As an inclusion position for the included file, use the file location of the file where it
was included but *after* the macro expansions. We want the macro expansions to be considered
as before-in-translation-unit for everything in the included file.

-In the preprocessing record take into account that only inclusion directives can be encountered
as "out-of-order" (by comparing the start of the range which for inclusions is the hash location)
and use binary search if there is an extreme number of macro expansions in the include directive.

Fixes rdar://11111779

Chandler Carruth 979272c01c Change this test to reflect the state we are moving in. The Clang
builtin headers are no longer going to receive the old 'implicit extern
"C" block' semantics. This hint is actually ignored by both Clang and
GCC at this point, and Clang's own builtin headers can simply be changed
if there is any issue with this. Clang should be free to include these
however it wants, and so shorter and simpler is better.

Note: *nothing* is changing about the *system* stddef.h include. That
should always have the exact same include semantics, whether with Clang
or GCC or any other compiler. Only the compiler-builtin header search
path is changing.

If anyone knows of some risk that this introduces that I've not thought
of, please chime in. So far, only Windows has switched to the Brave New
World, but others should be switching soon.

John McCall 9b0a7cea0f Make -fobjc-nonfragile-abi the -cc1 default, since it's the
increasingly prevailing case to the point that new features
like ARC don't even support the fragile ABI anymore.

This required a little bit of reshuffling with exceptions
because a check was assuming that ObjCNonFragileABI was
only being set in ObjC mode, and that's actually a bit
obnoxious to do.

Most, though, it involved a perl script to translate a ton
of test cases.

Mostly no functionality change for driver users, although
there are corner cases with disabling language-specific
exceptions that we should handle more correctly now.

commits, but I need to get this checkpoint in place for sanity.

This also adds a much more comprehensive test for architecture macros,
which is roughly generated by inspecting the behavior of a trunk build
of GCC. It still requires some massaging, but eventually I'll even check
in the script that generates these so that others can use it to append
more tests for more architectures, etc.

Next up is a bunch of simplification of the Targets.cpp code, followed
by a lot more test cases once we can reject invalid architectures.

Diagnostic pragmas are broken because we don't keep track of the diagnostic state changes and we only check the current/latest state.
Problems manifest if a diagnostic is emitted for a source line that has different diagnostic state than the current state; this can affect
a lot of places, like C++ inline methods, template instantiations, the lexer, etc.

Fix the issue by having the Diagnostic object keep track of the source location of the pragmas so that it is able to know what is the diagnostic state at any given source location.

Daniel Dunbar 120a1e9d0f Headers: Define __INT64_TYPE__ in terms of getInt64Type(), which isn't always
'long'. The practical upshot is so that the uint64_t we define in our stdint.h
ends up being compatible with that defined by gcc (at least on Darwin), which
otherwise could lead to type incompatibilities with other system headers.

Daniel Dunbar 0def3d17cb ARM: Honor -mfpu= and set __VFP_FP__ and __ARM_NEON__ "correctly".

 - Also, fix the arch define for arm1136jf-s.

Daniel Dunbar 8fbe78f6fc Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.
- This is designed to make it obvious that %clang_cc1 is a "test variable"
   which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
   can be useful to redefine what gets run as 'clang -cc1' (for example, to set
   a default target).
