Renato Golin c4b4924a13 Add EXPERIMENTAL --rtlib=compiler-rt to GNU Clang
This commit is not strictly correct nor accounts for all uses (shared
objects, for example), but it allows one to test the compiler-rt library
on GNU targets.

Using this patch to run the test-suite has already shown me problems
on ARM. Since this is a Darwin-only flag, nobody is using it, so it
shouldn't be a problem.

I will need extension to deal with the shared cases, but since we're
not compiling libclang_rt.so, that's not yet applicable. Many other
problems will have to be fixed first in compiler-rt (such as removing
the 'arch' name from it and making it trully multi-arch, moving it to
the default lib directory, make both .a and .so variants, etc).

Reid Kleckner c0dca6ded7 MS ABI: Implement #pragma vtordisp() and clang-cl /vdN
These features are new in VS 2013 and are necessary in order to layout
std::ostream correctly.  Currently we have an ABI incompatibility when
self-hosting with the 2013 stdlib in our convertible_fwd_ostream wrapper
in gtest.

This change adds another implicit attribute, MSVtorDispAttr, because
implicit attributes are currently the best way to make sure the
information stays on class templates through instantiation.

Dmitri Gribenko ea4d1c32fb libclang: report error code for bad PCH files
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.

Dmitri Gribenko f430da4de6 Add an option to allow Clang verify source files for a module only once during
the build

When Clang loads the module, it verifies the user source files that the module
was built from.  If any file was changed, the module is rebuilt.  There are two
problems with this:
1. correctness: we don't verify system files (there are too many of them, and
   stat'ing all of them would take a lot of time);
2. performance: the same module file is verified again and again during a
   single build.

This change allows the build system to optimize source file verification.  The
idea is based on the fact that while the project is being built, the source
files don't change.  This allows us to verify the module only once during a
single build session.  The build system passes a flag,
-fbuild-session-timestamp=, to inform Clang of the time when the build started.
The build system also requests to enable this feature by passing
-fmodules-validate-once-per-build-session.  If these flags are not passed, the
behavior is not changed.  When Clang verifies the module the first time, it
writes out a timestamp file.  Then, when Clang loads the module the second
time, it finds a timestamp file, so it can compare the verification timestamp
of the module with the time when the build started.  If the verification
timestamp is too old, the module is verified again, and the timestamp file is
updated.

allow the alignment of vbases to affect required alignment until just
before we insert the vtordisp field.

Another test that's testing through assembly from Clang which is

David Blaikie 68ccb3b6de Remove bad debug info test.
This test case doesn't belong in Clang (it's testing IndVarSimplify) but
in an effort to reproduce the test case this was intended to cover (by
essentially reverting r134441) I wasn't able to reproduce the failure
this test case should've produced. So I haven't ported this down to
LLVM, instead I'm just deleting it.

I suspect the test is just underconstrained, but I've no great interest
in trying hard to fix it right now - if anyone else wants to, I'd be
more than welcome to that.

Jordan Rose c939907a5a 'nonnull(1)' on a block parameter should apply to the block's argument.
Thanks to r199467, __attribute__((nonnull)) (without arguments) can apply
directly to parameters, instead of being applied to the whole function.
However, the old form of nonnull (with an argument index) could also apply
to the arguments of function and block pointers, and both of these can be
passed as parameters.

Now, if 'nonnull' with an argument is found on a parameter, /and/ the
parameter is a function or block pointer, it is handled the old way.

Introduce a notion of a 'current representation method' for
pointers-to-members.

When starting out, this is set to 'best case' (representation method is
chosen by examining the class, selecting the smallest representation
that would work given the class definition or lack thereof).

This pragma allows the translation unit to dictate exactly what
representation to use, similar to how the inheritance model keywords
operate.

N.B.  PCH support is forthcoming.

Reid Kleckner 42063b0b1c Move the -fms-compatibility using decl check after real access checking
Summary:
This avoids false positives from -Wmicrosoft when name lookup would
normally succeed in standard C++.  This triggered on a common CRTP
pattern in clang, where a derived class would have a private using decl
to pull in members of a dependent base:

class Verifier : InstVisitor<Verifier> {
private:
  using InstVisitor<Verifier>::visit;
  ...
  void anything() {
    visit(); // warned here
  }
};

Real access checks pass here because we're in the context of the
Verifier, but the -Wmicrosoft extension was just looking for the private
access specifier.

  N.B. We will chose an inheritance model even if we won't ultimately

    template<class T> void f() { T arr[A::sz]; }

the array 'arr' is represented as a variable size array in the template.
If 'A::sz' gets value below in the translation unit, the array in
instantiation can turn into constant size array.

Manman Ren 67a28136ad PGO: instrumentation based profiling sets function attributes.
We collect a maximal function count among all functions in the pgo data file.
For functions that are hot, we set its InlineHint attribute. For functions that
are cold, we set its Cold attribute.

We currently treat functions with >= 30% of the maximal function count as hot
and functions with <= 1% of the maximal function count are treated as cold.
These two numbers are from preliminary tuning on SPEC.

This commit should not affect non-PGO builds and should boost performance on
instrumentation based PGO.

Reid Kleckner 96f8f9339d MS ABI: Mangle member pointer template arguments
Member pointers are mangled as they would be represented at runtime.
They can be a single integer literal, single decl, or a tuple with some
more numbers tossed in.  With Clang today, most of those numbers will be
zero because we reject pointers to members of virtual bases.

This change required moving VTableContextBase ownership from
CodeGenVTables to ASTContext, because mangling now depends on vtable
layout.

I also hoisted the inheritance model helpers up to be inline static
methods of MSInheritanceAttr.  This makes the AST code that deals with
member pointers much more readable.

MSVC doesn't appear to have stable manglings of null member pointers:
- Null data memptrs in function templates have a mangling collision with
  the first field of a non-polymorphic single inheritance class.
- The mangling of null data memptrs changes if you add casts.
- Large null function memptrs in class templates crash MSVC.

Clang uses the class template mangling for null data memptrs and the
function template mangling for null function memptrs to deal with this.

John McCall 9b595db16d Tighten lax vector-conversion rules and enforce them consistently.
When a lax conversion featured a vector and a non-vector, we were
only requiring the non-vector to be a scalar type, but really it
needs to be a real type (i.e. integral or real floating); it is
not reasonable to allow a pointer, member pointer, or complex
type here.

r198474 required lax conversions to match in "data size", i.e.
element size * element count, forbidding matches that happen
only because a vector is rounded up to the nearest power of two
in size.  Unfortunately, the erroneous logic was repeated in
several different places; unify them to use the new condition,
so that it triggers for arbitrary conversions and not just
those performed as part of binary operator checking.

Justin Bogner 79c93845f6 Fix whitespace handling in empty macro expansions
When a macro expansion does not result in any tokens, and the macro name
is preceded by whitespace, the whitespace should be passed to the first
token that follows the macro expansion. Similarly when a macro expansion
ends with a placemarker token, and that placemarker token is preceded by
whitespace. This worked already for top-level macro expansions, but is
now extended to also work for nested macro expansions.

the existing NextTokGetsSpace to a preserved bit-field and checking it

token following the macro expansion result.

not be. This patch removes the checks for whitespace before ## and
before y, and in the special case where x is an empty macro argument and
y is a regular token, actively removes whitespace before y.

Bob Wilson 5cfc55e49f Fix an assertion failure when building for the iOS simulator. rdar://15959009
When building for i386 or x86_64 with IPHONEOS_DEPLOYMENT_TARGET set in the
environment, the toolchain correctly recognizes that the target platform is
the iOS simulator. The code in Darwin::addMinVersionArgs was not updated for
svn 197148, where isTargetIPhoneOS() was widely replaced by isTargetIOSBased().
This is kind of a strange case, though, because we probably ought to be
passing -ios_simulator_version_min to the linker, but according to the FIXME
in the code, we intentionally avoid that unless the -mios-simulator-version-min
option was used. I don't know whether it is safe to change that yet, so
for now, I am just fixing the assertion failure.

Reid Kleckner 314ef7bafd [ms-cxxabi] Use inalloca on win32 when passing non-trivial C++ objects
When a non-trivial parameter is present, clang now gathers up all the
parameters that lack inreg and puts them into a packed struct.  MSVC
always aligns each parameter to 4 bytes and no more, so this is a pretty
simple struct to lay out.

On win64, non-trivial records are passed indirectly.  Prior to this
change, clang was incorrectly using byval on win64.

I'm able to self-host a working clang with this change and additional

This fixes PR15768, where the sret parameter and the 'this' parameter

Instance methods compiled by MSVC never return records in registers,
they always return indirectly through an sret pointer.  That sret

__thiscall methods.

Unfortunately, the same is true for other calling conventions, so we'll
have to change the overall approach here relatively soon.

This starts to switch ARCMT to use proper diagnostic messages. The old use was

The logic of the previous report() functions has been retained to support any
external consumers that might be intercepting diagnostic messages through the

Note that the change in test/Misc/warning-flags.c isn't a new warning without a
flag, rather one that was previously invisible to the test. Adding a flag might

Serge Pavlov 09f9924acf Fix to PR8880 (clang dies processing a for loop)
Due to statement expressions supported as GCC extension, it is possible
to put 'break' or 'continue' into a loop/switch statement but outside
its body, for example:

    for ( ; ({ if (first) { first = 0; continue; } 0; }); )

This code is rejected by GCC if compiled in C mode but is accepted in C++
code. GCC bug 44715 tracks this discrepancy. Clang used code generation
that differs from GCC in both modes: only statement of the third
expression of 'for' behaves as if it was inside loop body.

This change makes code generation more close to GCC, considering 'break'
or 'continue' statement in condition and increment expressions of a
loop as it was inside the loop body. It also adds error for the cases
when 'break'/'continue' appear outside loop due to this syntax. If
code generation differ from GCC, warning is issued.

Tim Northover 5a68c4b287 MachO embedded: default to soft float without issuing warning
This is a simpler rule, broadly in line with previous Darwin (which chose
between "soft" and "softfp") but probably safer. In practice the only real
reason for "softfp" is ABI compatibility, not usually an issue on limited chips
like these, so anyone who wanted hard-float should already be saying so.

That's my story and I'm sticking to it.

Richard Smith 8c7bd6ac1a Don't forget about a builtin if we're about to redeclare it and we couldn't
create an implicit declaration of it (because some type it depends on is
unavailable). This had the effect of causing us to not implicitly give it the
right attributes. It turns out that glibc's __sigsetjmp is declared before
sigjmp_buf is declared, and this resulted in us not implicitly giving it
__attribute__((returns_twice)), which in turn resulted in miscompiles in any C
code calling glibc's sigsetjmp.
