Bob Wilson 57819fc809 Move the fixit for -Wformat-security to a note.
r263299 added a fixit for the -Wformat-security warning, but that runs
into complications with our guideline that error recovery should be done
as-if the fixit had been applied. Putting the fixit on a note avoids that.

Evgeniy Stepanov 02279ed12d [cfi] Don't emit checks for disabled CFI kinds.
In the cross-DSO CFI mode clang emits __cfi_check_fail that handles
errors triggered from other modules with targets in the current
module. With this change, __cfi_check_fail will handle errors for
CFI kinds that are not enabled in the current module as if they
have the trapping behaviour (-fsanitize-trap=...).

This fixes a bug where some combinations of -fsanitize* flags may
result in a link failure due to a missing sanitizer runtime library
for the diagnostic calls in __cfi_check_fail.

John Brawn 6c78974b29 Make it possible for AST plugins to enable themselves by default
Currently when an AST plugin is loaded it must then be enabled by passing
-plugin pluginname or -add-plugin pluginname to the -cc1 command line. This
patch adds a method to PluginASTAction which allows it to declare that the
action happens before, instead of, or after the main AST action, plus the
relevant changes to make the plugin action happen at that time automatically.

Daniel Jasper 1dcbbcfc5c clang-format: [JS] Handle certain cases of ASI.
Automatic Semicolon Insertion can only be properly handled by parsing
source code. However conservatively catching just a few, common
situations prevents breaking code during development, which greatly
improves usability.

JS code should still use semicolons, and ASI code should be flagged by
a compiler or linter.

Peter Collingbourne 4e6a540024 CodeGen: Use 32-bit gep offsets to address vtable address points.
The relative vtable ABI will use a struct rather than an array as the type
of a vtable. LLVM only allows 32-bit integers as struct indices, so we need
to use 32-bit integers to get addresses of address points. In order to keep
the code simple, we might as well do that unconditionally.

It's probably a reasonable implementation limit to support no more than 2
billion virtual functions per class.

This change causes quite a bit of churn in the test suite, so I'm making
it separately.

Samuel Antao aeb7b539f5 [OpenMP] Replace offloading option that start with -o with -fo.
Summary:
The current offloading implementation is using -omptargets and -omp-host-ir-file-path options in the frontend. This causes the user a lot of trouble due to to the conflicts with the -o option. E.g. if the user misspells  omptargets he will end up with a file with a weird name.

This patches replaces these two options with  -fomptargets and -fomp-host-ir-file-path to avoid these issues, and it is also more consistent with the other options like -fopenmp.

Reid Kleckner 1af391df13 Allow sizeof(UnrelatedClass::field) in C++11 class template methods
This feature works outside of templates by forming a DeclRefExpr to a
FieldDecl instead of a MemberExpr, which requires a base object in
addition to the FieldDecl.

Previously, while building up the template AST before instantiation, we
formed a CXXDependentScopeMemberExpr, which always instantiates to a
MemberExpr. Now, in unevaluated contexts we form a
DependentScopeDeclRefExpr, which is a more flexible node that can
instantiate to either a MemberExpr or a DeclRefExpr depending on lookup
results.

Fixes PR26893.

Manman Ren 073db02476 Add TreatUnavailableAsInvalid for the verification-only mode in InitListChecker.
Given the following test case:
typedef struct {
  const char *name;
  id field;
} Test9;
extern void doSomething(Test9 arg);
void test9() {
  Test9 foo2 = {0, 0};
  doSomething(foo2);
}
With a release compiler, we don't emit any message and silently ignore the
variable "foo2". With an assert compiler, we get an assertion failure.

The root cause —————————————
Back in r140457 we gave InitListChecker a verification-only mode, and will use
CanUseDecl instead of DiagnoseUseOfDecl for verification-only mode.

These two functions handle unavailable issues differently:
In Sema::CanUseDecl, we say the decl is invalid when the Decl is unavailable and
the current context is available.

In Sema::DiagnoseUseOfDecl, we say the decl is usable by ignoring the return
code of DiagnoseAvailabilityOfDecl

So with an assert build, we will hit an assertion in diagnoseListInit
assert(DiagnoseInitList.HadError() &&
       "Inconsistent init list check result.");

The fix -------------------
If we follow what is implemented in CanUseDecl and treat Decls with
unavailable issues as invalid, the variable decl of “foo2” will be marked as
invalid. Since unavailable checking is processed in delayed diagnostics
(r197627), we will silently ignore the diagnostics when we find out that
the variable decl is invalid.

We add a flag "TreatUnavailableAsInvalid" for the verification-only mode.
For overload resolution, we want to say decls with unavailable issues are
invalid; but for everything else, we should say they are valid and
emit diagnostics. Depending on the value of the flag, CanUseDecl
can return different values for unavailable issues.

Peter Zotov e43b741359 Accept absolute paths in the -fuse-ld option.
This patch extends the -fuse-ld option to accept a full path to an executable
and use it verbatim to invoke the linker. There are generally two reasons
to desire this.

The first reason relates to the sad truth is that Clang is retargetable,
Binutils are not.

While any Clang from a binary distribution is sufficient to compile code
for a wide range of architectures and prefixed BFD linkers (e.g.
installed as /usr/bin/arm-none-linux-gnueabi-ld) as well as cross-compiled
libc's (for non-bare-metal targets) are widely available, including on all
Debian derivatives, it is impossible to use them together because
the -fuse-ld= option allows to specify neither a linker prefix nor
a full path to one.

The second reason is linker development, both when porting existing linkers
to new architectures and when working on a new linker such as LLD.

Duncan P. N. Exon Smith 8536392a83 Sema: Methods in unavailable classes are unavailable
Similar to the template cases in r262050, when a C++ method in an
unavailable struct/class calls unavailable API, don't diagnose an error.
I.e., this case was failing:

    void foo() __attribute__((unavailable));
    struct __attribute__((unavailable)) A {
      void bar() { foo(); }
    };

Since A is unavailable, A::bar is allowed to call foo.  However, we were
emitting a diagnostic here.  This commit checks up the context chain
from A::bar, in a manner inspired by SemaDeclAttr.cpp:isDeclUnavailable.

I expected to find other related issues but failed to trigger them:

- I wondered if DeclBase::getAvailability should check for
  `TemplateDecl` instead of `FunctionTemplateDecl`, but I couldn't find
  a way to trigger this.  I left behind a few extra tests to make sure
  we don't regress.

- I wondered if Sema::isFunctionConsideredUnavailable should be
  symmetric, checking up the context chain of the callee (this commit
  only checks up the context chain of the caller).  However, I couldn't
  think of a testcase that didn't require first referencing the
  unavailable type; this, we already diagnose.

Duncan P. N. Exon Smith 5d6790c746 Sema: Treat 'strict' availability flag like unavailable
This is a follow-up to r261512, which made the 'strict' availability
attribute flag behave like 'unavailable'.  However, that fix was
insufficient.  The following case would (erroneously) error when the
deployment target was older than 10.9:

    struct __attribute__((availability(macosx,strict,introduced=10.9))) A;
    __attribute__((availability(macosx,strict,introduced=10.9))) void f(A*);

The use of A* in the argument list for f is valid here, since f and A
have the same availability.

The fix is to return AR_Unavailable from DeclBase::getAvailability
instead of AR_NotYetIntroduced.  This also reverts the special handling
added in r261163, instead relying on the well-tested logic for
AR_Unavailable.

Richard Smith 4f902c7ecc P0188R1: add support for standard [[fallthrough]] attribute. This is almost
exactly the same as clang's existing [[clang::fallthrough]] attribute, which
has been updated to have the same semantics. The one significant difference
is that [[fallthrough]] is ill-formed if it's not used immediately before a
switch label (even when -Wimplicit-fallthrough is disabled). To support that,
we now build a CFG of any function that uses a '[[fallthrough]];' statement
to check.

In passing, fix some bugs with our support for statement attributes -- in
particular, diagnose their use on declarations, rather than asserting.

Marina Yatsina 5f77679356 [ms-inline-asm][AVX512] Add ability to use k registers in MS inline asm + fix bag with curly braces
Until now curly braces could only be used in MS inline assembly to mark block start/end.
All curly braces were removed completely at a very early stage.
This approach caused bugs like:
"m{o}v eax, ebx" turned into "mov eax, ebx" without any error.

In addition, AVX-512 added special operands (e.g., k registers), which are also surrounded by curly braces that mark them as such.
Now, we need to keep the curly braces and identify at a later stage if they are marking block start/end (if so, ignore them), or surrounding special AVX-512 operands (if so, parse them as such).

This patch fixes the bug described above and enables the use of AVX-512 special operands.

David Majnemer febb27283d [MS ABI] Mangle symbols names longer than 4096 characters correctly
Really long symbols are hashed using MD5 and prefixed/suffixed with the
usual sigils.  There is an additional reason beyond the usual
compatibility with MSVC, it is important to keep COFF symbols shorter
than 0xFFFF because the CodeView debugging format has a maximum
symbol/record size of 0xFFFF.

There are some quirks worth noting:
- Some mangled names reference other entities which are mangled
separately.  A quick example:

int I;
template <int *> struct S {};
S<I> s;

In this case, the mangling for 's' doesn't depend directly on the
mangling for 'I'.  While 's' would need an MD5 hash if 'I' also needed
one, the hash for 's' applied to the fully realized mangled name.  In
other words, the mangled name for 's' will not depend on the MD5 of the
mangled name for 'I'.

- Some mangled names, like the venerable CatchableType, embed the MD5
verbatim.

- Finally, the complete object locator is handled as a special case.
A complete object locators are mangled exactly like a VFTable except for
a small deviation in the prefix sigils.  However, complete object
locators for hashed vftables result in a complete object locator whose
name is identical to the vftable except for an additional suffix.

instructions like sdiv, which are present for krait. Cortex-a15 is the
closest subset of functionality for krait, so we should switch the
assembler to use that instead.

This fixes a test failure in LLDB, which always creates object with invalid source locations as it
does not (always) have access to the source.

Alexey Bataev 94a4f0cb5f [OPENMP 4.0] Initial support for 'omp declare reduction' construct.
Add parsing, sema analysis and serialization/deserialization for 'declare reduction' construct.
User-defined reductions are defined as

#pragma omp declare reduction( reduction-identifier : typename-list : combiner ) [initializer ( initializer-expr )]
These custom reductions may be used in 'reduction' clauses of OpenMP constructs. The combiner specifies how partial results can be combined into a single value. The
combiner can use the special variable identifiers omp_in and omp_out that are of the type of the variables being reduced with this reduction-identifier. Each of them will
denote one of the values to be combined before executing the combiner. It is assumed that the special omp_out identifier will refer to the storage that holds the resulting
combined value after executing the combiner.
As the initializer-expr value of a user-defined reduction is not known a priori the initializer-clause can be used to specify one. Then the contents of the initializer-clause
will be used as the initializer for private copies of reduction list items where the omp_priv identifier will refer to the storage to be initialized. The special identifier
omp_orig can also appear in the initializer-clause and it will refer to the storage of the original variable to be reduced.

This makes it more convenient to follow the Google JavaScript style

This functionality is behind the option "JavaScriptQuotes", which can be:

  * "leave" (no re-quoting)
  * "single" (change to single quotes)
  * "double" (change to double quotes)

This also changes single quoted JavaScript string literals to be treated

Nico Weber 2ca4be97de clang-cl: Implement initial limited support for precompiled headers.
In the gcc precompiled header model, one explicitly runs clang with `-x
c++-header` on a .h file to produce a gch file, and then includes the header
with `-include foo.h` and if a .gch file exists for that header it gets used.
This is documented at
http://clang.llvm.org/docs/UsersManual.html#precompiled-headers

cl.exe's model is fairly different, and controlled by the two flags /Yc and
/Yu. A pch file is generated as a side effect of a regular compilation when
/Ycheader.h is passed. While the compilation is running, the compiler keeps
track of #include lines in the main translation unit and writes everything up
to an `#include "header.h"` line into a pch file. Conversely, /Yuheader.h tells
the compiler to skip all code in the main TU up to and including `#include
"header.h"` and instead load header.pch. (It's also possible to use /Yc and /Yu
without an argument, in that case a `#pragma hrdstop` takes the role of
controlling the point where pch ends and real code begins.)

This patch implements limited support for this in that it requires the pch
header to be passed as a /FI force include flag – with this restriction,
it can be implemented almost completely in the driver with fairly small amounts
of code. For /Yu, this is trivial, and for /Yc a separate pch action is added
that runs before the actual compilation. After r261774, the first failing
command makes a compilation stop – this means if the pch fails to build the
main compilation won't run, which is what we want. However, in /fallback builds
we need to run the main compilation even if the pch build fails so that the
main compilation's fallback can run. To achieve this, add a ForceSuccessCommand
that pretends that the pch build always succeeded in /fallback builds (the main
compilation will then fail to open the pch and run the fallback cl.exe
invocation).

If /Yc /Yu are used in a setup that clang-cl doesn't implement yet, clang-cl
will now emit a "not implemented yet; flag ignored" warning that can be
disabled using -Wno-clang-cl-pch.

Since clang-cl doesn't yet serialize some important things (most notably
`pragma comment(lib, ...)`, this feature is disabled by default and only
enabled by an internal driver flag. Once it's more stable, this internal flag
will disappear.

(The default stdafx.h setup passes stdafx.h as explicit argument to /Yc but not
as /FI – instead every single TU has to `#include <stdafx.h>` as first thing it
does. Implementing support for this should be possible with the approach in
this patch with minimal frontend changes by passing a --stop-at / --start-at
flag from the driver to the frontend. This is left for a follow-up. I don't
think we ever want to support `#pragma hdrstop`, and supporting it with this
approach isn't easy: This approach relies on the driver knowing the pch
filename in advance, and `#pragma hdrstop(out.pch)` can set the output
filename, so the driver can't know about it in advance.)

clang-cl now also honors /Fp and puts pch files in the same spot that cl.exe
would put them, but the pch file format is of course incompatible. This has
ramifications on /fallback, so /Yc /Yu aren't passed through to cl.exe in
/fallback builds.

John McCall 07daf721fb Mangle extended qualifiers in the proper order and mangle the
ARC ownership-convention function type modifications.

According to the Itanium ABI, vendor extended qualifiers are
supposed to be mangled in reverse-alphabetical order before
any CVR qualifiers.  The ARC function type conventions are
plausibly order-significant (they are associated with the
function type), which permits us to ignore the need to correctly
inter-order them with any other vendor qualifiers on the parameter
and return types.

Implementing these rules correctly is technically an ABI break.
Apple is comfortable with the risk of incompatibility here for
the ARC features, and I believe that address-space qualification
is still uncommon enough to allow us to adopt the conforming
rule without serious risk.  Still, targets which make heavy
use of address space qualification may want to revert to the
non-conforming order.

Devin Coughlin 3fc67e47e5 [analyzer] Don't treat calls to system headers as escaping in CheckObjCDealloc.
This prevents false negatives when a -dealloc method, for example, removes itself as
as an observer with [[NSNotificationCenter defaultCenter] removeObserver:self]. It is
unlikely that passing 'self' to a system header method will release 'self''s instance
variables, so this is unlikely to produce false positives.

A challenge here is that while CheckObjCDealloc no longer treats these calls as
escaping, the rest of the analyzer still does. In particular, this means that loads
from the same instance variable before and after a call to a system header will
result in different symbols being loaded by the region store. To account for this,
the checker now treats different ivar symbols with the same instance and ivar decl as
the same for the purpose of release checking and more eagerly removes a release
requirement when an instance variable is assumed to be nil. This was not needed before
because when an ivar escaped its release requirement was always removed -- now the
requirement is not removed for calls to system headers.

with a prior UsingDecl -- those should not even really be found by the lookup
here, except that we use the same lookup results for two different checks, and
the other check needs them.

This happens to work in *almost all* cases, because either the lookup results
list the UsingDecl first (and the NonTag result gets replaced by something
else) or because the problematic declaration is a function (which causes us to
use different logic to detect conflicts). This can also be triggered from a
state only reachable through modules (where the name lookup results can contain
multiple UsingDecls in the same scope).

Relands r260194 with a fix. If we have a template that transitions from
an extern template to an explicitly instantiated dllexport template, we
would add that class to the delayed exported class list without flushing
it.

For explicit instantiations, we can just flush the list of delayed
classes immediately. We don't have to worry about the bug fixed in
r260194 in this case because explicit instantiations can only occur at

This adds tests for availability in templates in many other cases, but

(within the DeclRefExpr Node) when creating AST nodes that reference specializations of static data member templates.  While we pass the template args through for all non-instance members, they should only be relevant (i.e. non-null) for variable template ids (assertion added for that assumption)

Also preserve the FoundDecl that refers to the canonical Decl (the  primary VarTemplateDecl for a variable template specialization) that we are referencing in our DeclRefExpr. Not sure why this was not being done for non-variable template-ids.  

No functionality change - so no tests added.

Justin Lebar ddd97faeec [CUDA] Mark all CUDA device-side function defs, decls, and calls as convergent.
Summary:
This is important for e.g. the following case:

  void sync() { __syncthreads(); }
  void foo() {
    do_something();
    sync();
    do_something_else():
  }

Without this change, if the optimizer does not inline sync() (which it
won't because __syncthreads is also marked as noduplicate, for now
anyway), it is free to perform optimizations on sync() that it would not
be able to perform on __syncthreads(), because sync() is not marked as
convergent.

Similarly, we need a notion of convergent calls, since in the case when
we can't statically determine a call's target(s), we need to know
whether it's safe to perform optimizations around the call.

This change is conservative; the optimizer will remove these attrs where
it can, see r260318, r260319.

builtin classes.  So these redefinitions are incompatible.

Justin Lebar 8671c441c3 Bail on compilation as soon as a job fails.
Summary:
(Re-land of r260448, which was reverted in r260522 due to a test failure
in Driver/output-file-cleanup.c that only showed up in fresh builds.)

Previously we attempted to be smart; if one job failed, we'd run all
jobs that didn't depend on the failing job.

Problem is, this doesn't work well for e.g. CUDA compilation without
-save-temps.  In this case, the device-side and host-side Assemble
actions (which actually are responsible for preprocess, compile,
backend, and assemble, since we're not saving temps) are necessarily
distinct.  So our clever heuristic doesn't help us, and we repeat every
error message once for host and once for each device arch.

The main effect of this change, other than fixing CUDA, is that if you
pass multiple cc files to one instance of clang and you get a compile
error, we'll stop when the first cc1 job fails.

James Y Knight 29b5f086ca Default vaarg lowering should support indirect struct types.
Fixes PR11517 for SPARC.

On most targets, clang lowers va_arg itself, eschewing the use of the
llvm vaarg instruction. This is necessary (at least for now) as the type
argument to the vaarg instruction cannot represent all the ABI
information that is needed to support complex calling conventions.

However, on targets with a simpler varrags ABIs, the LLVM instruction
can work just fine, and clang can simply lower to it. Unfortunately,
even on such targets, vaarg with a struct argument would fail, because
the default lowering to vaarg was naive: it didn't take into account the
ABI attribute computed by classifyArgumentType. In particular, for the
DefaultABIInfo, structs are supposed to be passed indirectly and so
llvm's vaarg instruction should be emitted with a pointer argument.

Now, vaarg instruction emission is able to use computed ABIArgInfo for
the provided argument type, which allows the default ABI support to work
for structs too.

I haven't touched the EmitVAArg implementation for PPC32_SVR4 or XCore,
although I believe both are now redundant, and could be switched over to
use the default implementation as well.

Adrian Prantl 4594606c00 Reapply r261657.
Remove an unnecessary workaround introduced in r259975. (NFC)

Now that LLVM r259973 allows replacing a temporary type with another
temporary we can rely on the original implementation.

It is possible for enums to be created as part of
their own declcontext. In this case a FwdDecl will be created
twice. This doesn't cause a problem because both FwdDecls are
entered into the ReplaceMap: finalize() will replace the first
FwdDecl with the second and then replace the second with
complete type.

Thanks to echristo for pointing this out.

Bruno Cardoso Lopes 8c03c54200 [VFS] Add 'overlay-relative' field to YAML files
The VFS overlay mapping between virtual paths and real paths is done through
the 'external-contents' entries in YAML files, which contains hardcoded paths
to the real files.

When a module compilation crashes, headers are dumped into <name>.cache/vfs
directory and are mapped via the <name>.cache/vfs/vfs.yaml. The script
generated for reproduction uses -ivfsoverlay pointing to file to gather the
mapping between virtual paths and files inside <name>.cache/vfs. Currently, we
are only capable of reproducing such crashes in the same machine as they
happen, because of the hardcoded paths in 'external-contents'.

To be able to reproduce a crash in another machine, this patch introduces a new
option in the VFS yaml file called 'overlay-relative'. When it's equal to
'true' it means that the provided path to the YAML file through the
-ivfsoverlay option should also be used to prefix the final path for every
'external-contents'.

Example, given the invocation snippet "... -ivfsoverlay
<name>.cache/vfs/vfs.yaml" and the following entry in the yaml file:

"overlay-relative": "true",
"roots": [
...
  "type": "directory",
  "name": "/usr/include",
  "contents": [
    {
      "type": "file",
      "name": "stdio.h",
      "external-contents": "/usr/include/stdio.h"
    },
...

Here, a file manager request for virtual "/usr/include/stdio.h", that will map
into real path "/<absolute_path_to>/<name>.cache/vfs/usr/include/stdio.h.

This is a useful feature for debugging module crashes in machines other than
the one where the error happened.

Bruno Cardoso Lopes 956e6a0dc6 [VFS] Add support for handling path traversals
Handle ".", ".." and "./" with trailing slashes while collecting files
to be dumped into the vfs overlay directory.

Include the support for symlinks into components. Given the path:

/install-dir/bin/../lib/clang/3.8.0/include/altivec.h, if "bin"
component is a symlink, it's not safe to use `path::remove_dots` here,
and `realpath` is used to get the right answer. Since `realpath`
is expensive, we only do it at collecting time (which only happens
during the crash reproducer) and cache the base directory for fast lookups.

Overall, this makes the input to the VFS YAML file to be canonicalized
to never contain traversal components.

Duncan P. N. Exon Smith 96a01fa046 Lex: Never overflow the file in HeaderMap::lookupFilename()
If a header map file is corrupt, the strings in the string table may not
be null-terminated.  The logic here previously relied on `MemoryBuffer`
always being null-terminated, but this isn't actually guaranteed by the
class AFAICT.  Moreover, we're seeing a lot of crash traces at calls to
`strlen()` inside of `lookupFilename()`, so something is going wrong
there.

Instead, use `strnlen()` to get the length, and check for corruption.

Also remove code paths that could call `StringRef(nullptr)`.  r261459
made these rather obvious (although they'd been there all along).

There was already a check in `getBucket()`, but it had UB (comparing

JF Bastien 750caef39c ARM: fix VFP asm constraints
Summary:
Rich Felker was sad that clang used 'w' and 'P' for VFP constraints when GCC documents them as 't' and 'w':

Nico Weber 344abaa026 Fix SemaTemplate/instantiate-field.cpp after r261297.
For templates, fields can have incomplete types:

  template <class T>
  struct A2 {
    struct B;
    B b;
  };

Don't try to touch the DefinitionData of those fields.

Nico Weber 6a6376b17c Implement the likely resolution of core issue 253.
C++11 requires const objects to have a user-provided constructor, even for
classes without any fields. DR 253 relaxes this to say "If the implicit default
constructor initializes all subobjects, no initializer should be required."

clang is currently the only compiler that implements this C++11 rule, and e.g.
libstdc++ relies on something like DR 253 to compile in newer versions.  This
change  makes it possible to build code that says `const vector<int> v;' again
when using libstdc++5.2 and _GLIBCXX_DEBUG
(https://gcc.gnu.org/bugzilla/show_bug.cgi?id=60284).

Fixes PR23381.

Devin Coughlin 8d922aa746 [analyzer] Add checker callback for beginning of function.
Add a checker callback that is called when the analyzer starts analyzing a
function either at the top level or when inlined. This will be used by a
follow-on patch making the DeallocChecker path sensitive.
