Daniel Sanders 5a1449dab4 [mips] Make it impossible to have UnknownABI in CodeGen and Integrated Assembler.
Summary:
This removes the need to coerce UnknownABI to the default ABI (O32 for
MIPS32, N64 for MIPS64 [*]) in both MipsSubtarget and MipsAsmParser.

Clang has been updated to disable both possible default ABI's before enabling
the ABI it intends to use.

[*] N64 being the default for MIPS64 is not actually correct.
    However N32 is not fully implemented/tested yet.

Depends on: D2830

Daniel Jasper 2f0f297bdb Revert r201734 and r201742.
This breaks backwards compatibility with existing code. Previously, this
was defined as

  #define _mm_prefetch(a, sel) (__builtin_prefetch((void *)(a), 0, (sel)))

Which basically accepts any pointer. Changing this to char* simply
breaks a lot of existing code. I have tried changing char* to
"const void*", which seems to be the right thing as per Intel
specification this should work on basically any pointer. However,
apparently this breaks windows compatibility (because of a conflicting
declaration in windows.h).

So, we probably need to #ifdef this based on whether clang is compiling
for windows. According to Chandler, this might be done by introducing an
additional symbol to a fake type in BuiltinsX86.def and then condition
the type expansion on the platform.

Warren Hunt 40d6f29ad8 Add _mm_prefetch and some others as MS builtins
This patch adds several built-ins that are required for ms 
compatibility. _mm_prefetch must be a built-in because it takes a 
compile-time constant argument and our prior approach of using a #define 
to the current built-in doesn't work in the presence of re-declaration 
of _mm_prefetch. The others can be obtained by including the windows 
system headers. If a user includes the windows system headers but not 
intrin.h they still need to work and therefore must be built-in because 
we don't get a chance to implement them in intrin.h in this case.

Chandler Carruth e813984b43 Teach Clang to provide ::max_align_t in C11 and C++11 modes.
This definition is not chosen idly. There is an unfortunate reality with
max_align_t -- the specific nature of its definition leaks into the ABI
almost immediately. Because it is part of C11 and C++11 it becomes
essential for it to match with other systems on that ABI. There is an
effort to discourage any further use of this construct as a consequence
-- using max_align_t introduces an immediate ABI problem. We can never
update it to have larger alignment even as the microarchitecture changes
to necessitate higher alignment. =/

The particular definition here exactly matches the ABI of GCC's chosen
::max_align_t definition, for better or worse. This was written with the
help of Richard Smith who was decoding the exact ABI implications of the
selected definition in GCC. Notably, in-register arguments are impacted
by the particular definition chosen. =/

No one is under the illusion that this is a "good" or "useful"
definition of max_align_t, and we are working with the standards
committee to specify a more useful interface to address this need.

Jordan Rose 94008121fa [analyzer] Extend IdenticalExprChecker to check logical and bitwise expressions.
IdenticalExprChecker now warns if any expressions in a logical or bitwise

actually checks all subexpressions against each other (an O(N^2) operation,

Jordan Rose 70e7e8718e [analyzer] Extend IdenticalExprChecker to check the two branches of an if.
This extends the checks for identical expressions to handle identical
statements, and compares the consequent and alternative ("then" and "else")
branches of an if-statement to see if they are identical, treating a single
statement surrounded by braces as equivalent to one without braces.

This does /not/ check subsequent branches in an if/else chain, let alone
branches that are not consecutive. This may improve in a future patch, but
it would certainly take more work.

Tim Northover db3e5e2408 AArch64: look up EmitAArch64Scalar support before calling.
This fixes one immediate bug where an expression with side-effects
could be emitted twice during a NEON call.

It also prepares the way for folding CodeGen for many of the SISD
intrinsics into a table, reducing code size and hopefully increasing
performance eventually ("binary search + few switch cases" should be
better than "lots of switch cases").

Tim Northover 544e79eb30 ARM NEON: use more flexible TableGen field for defs.
We used to have special handling for isCrypto and isA64 bits in the
NeonEmitter.cpp file (it knew the former was predicated on __ARM_FEATURE_CRYPTO
and the latter on __aarch64__ and went through various contortions to make sure
the correct intrinsics were emitted under the correct guard.

This is ugly and has obvious scalability problems (e.g. vcvtX intrinsics are
needed, which are ARMv8 only but available on both, yet another category). This
patch moves the #if predicate into the arm_neon.td file directly and makes
NeonEmitter.cpp agnostic about what goes in there.

It also deduplicates arm_neon.td so that each desired intrinsic is mentioned in
just one place (necessary because of the new mechanism for creating
arm_neon.h).

Tim Northover 12670418a3 ARM & AArch64: merge the semantic checking of NEON intrinsics
There are two kinds of automatically generated tests for NEON intrinsics, both
of which can be merged without adversely affecting users.

1. We check that a valid kind of __builtin_neon_XYZ overload is requested (e.g.
   we're not asking for a float32x4_t version when it only accepts integers. Since
   the __builtin_neon_XYZ intrinsics should only be used in arm_neon.h, relaxing
   this test and permitting AArch64 types for AArch32 should not cause a problem.
   The extra arm_neon.h definitions should be #ifdefed out anyway.
2. We check that intrinsics which take immediates are actually given
   compile-time constants within range. Since all NEON intrinsics should be
   backwards compatible, these tests should be identical on AArch64 and AArch32
   anyway.

This patch, therefore, merges the separate AArch64 and 32-bit checks.

Reid Kleckner 0c12b36ebb MS ABI: Remove nv adjustment from direct vdtor calls and prologues
Summary:
Generally the vector deleting dtor, which we model as a vtable thunk,
takes care of non-virtual adjustment and delegates to the other
destructor variants.  The other non-complete destructor variants assume
that 'this' on entry points to the virtual base subobject that first
declared the virtual destructor.

We need to change the adjustment in both the prologue and the vdtor call
setup.

Ted Kremenek 5b2c210e65 Experiment with making -Wunreachable-code more immediately useful by restricting warnings to those issued in the main file.
This warning has a whole bunch of known false positives, much of them due
to code that is "sometimes unreachable".  This can caused by code that
is conditionally generated by the preprocessor, branches that are defined
in terms of architecture-specific details (e.g., the size of a type), and
so on.  While these are all good things to address one by one, the reality
is that this warning has received little love lately.  By restricting
its purvue, we can focus on the top issues effecting main files, which
should be smaller, and then gradually widen the scope.

Aaron Ballman efe348ec44 DeLesley Hutchins (who wrote the original thread-safety attribute functionality) and I have agreed to start migrating from lock-specific terminology to "capability"-specific terminology. This opens the door for future threading-related analysis passes so that a common nomenclature can be used.
The following attributes have been (silently) deprecated, with their replacements listed:

lockable => capability
exclusive_locks_required => requires_capability
shared_locks_required => requires_shared_capability
locks_excluded => requires_capability

There are no functional changes intended.

Bob Wilson bf854f0f53 Change PGO instrumentation to compute counts in a separate AST traversal.
Previously, we made one traversal of the AST prior to codegen to assign
counters to the ASTs and then propagated the count values during codegen. This
patch now adds a separate AST traversal prior to codegen for the
-fprofile-instr-use option to propagate the count values. The counts are then
saved in a map from which they can be retrieved during codegen.

This new approach has several advantages:

1. It gets rid of a lot of extra PGO-related code that had previously been
added to codegen.

2. It fixes a serious bug. My original implementation (which was mailed to the
list but never committed) used 3 counters for every loop. Justin improved it to
move 2 of those counters into the less-frequently executed breaks and continues,
but that turned out to produce wrong count values in some cases. The solution
requires visiting a loop body before the condition so that the count for the
condition properly includes the break and continue counts. Changing codegen to
visit a loop body first would be a fairly invasive change, but with a separate
AST traversal, it is easy to control the order of traversal. I've added a
testcase (provided by Justin) to make sure this works correctly.

3. It improves the instrumentation overhead, reducing the number of counters for
a loop from 3 to 1. We no longer need dedicated counters for breaks and
continues, since we can just use the propagated count values when visiting
breaks and continues.

To make this work, I needed to make a change to the way we count case
statements, going back to my original approach of not including the fall-through
in the counter values. This was necessary because there isn't always an AST node
that can be used to record the fall-through count. Now case statements are
handled the same as default statements, with the fall-through paths branching
over the counter increments.  While I was at it, I also went back to using this
approach for do-loops -- omitting the fall-through count into the loop body
simplifies some of the calculations and make them behave the same as other
loops. Whenever we start using this instrumentation for coverage, we'll need
to add the fall-through counts into the counter values.

Daniel Sanders 753e17629d Re-commit: Demote EmitRawText call in AsmPrinter::EmitInlineAsm() and remove hasRawTextSupport() call
Summary:
AsmPrinter::EmitInlineAsm() will no longer use the EmitRawText() call for
targets with mature MC support. Such targets will always parse the inline
assembly (even when emitting assembly). Targets without mature MC support
continue to use EmitRawText() for assembly output.

The hasRawTextSupport() check in AsmPrinter::EmitInlineAsm() has been replaced
with MCAsmInfo::UseIntegratedAs which when true, causes the integrated assembler
to parse inline assembly (even when emitting assembly output). UseIntegratedAs
is set to true for targets that consider any failure to parse valid assembly
to be a bug. Target specific subclasses generally enable the integrated
assembler in their constructor. The default value can be overridden with
-no-integrated-as.

All tests that rely on inline assembly supporting invalid assembly (for example,
those that use mnemonics such as 'foo' or 'hello world') have been updated to
disable the integrated assembler.

Changes since review (and last commit attempt):
- Fixed test failures that were missed due to configuration of local build.
  (fixes crash.ll and a couple others).
- Fixed tests that happened to pass because the local build was on X86
  (should fix 2007-12-17-InvokeAsm.ll)
- mature-mc-support.ll's should no longer require all targets to be compiled.
  (should fix ARM and PPC buildbots)
- Object output (-filetype=obj and similar) now forces the integrated assembler
  to be enabled regardless of default setting or -no-integrated-as.
  (should fix SystemZ buildbots)

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).

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.

2014-02-12 10:40:07 +00:00
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.

Summary:
In clang-tidy we'd like to know the name of the checker producing each
diagnostic message. PathDiagnostic has BugType and Category fields, which are
both arbitrary human-readable strings, but we need to know the exact name of the
checker in the form that can be used in the CheckersControlList option to
enable/disable the specific checker.

This patch adds the CheckName field to the CheckerBase class, and sets it in
the CheckerManager::registerChecker() method, which gets them from the
CheckerRegistry.

Checkers that implement multiple checks have to store the names of each check
in the respective registerXXXChecker method.

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.

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

NAKAMURA Takumi 3686e38c3d Fix Clang install rules to not set permissions on include/
The CMake install(DIRECTORY) command documents that it sets permissions
on directories it is asked to install.  Since the <prefix>/include
directory may not be exclusive to the LLVM/Clang installation, we should
not ask CMake to manage permissions of that directory for us.  Instead,
give only our own include/clang and include/clang-c subdirectories to
the install(DIRECTORY) command.

Fixes PR4500. Patch by Brad King.

David Blaikie 6cab596218 Improve diagnostic for using non-class/namespace/scoped enum in a nested name specifier.
Rather than simply saying "X is not a class or namespace", clarify what
X is by providing the aka type in the case where X is a type, or
pointing to the named declaration if there's an unambiguous one to refer
to. In the ambiguous case, the ambiguities are already enumerated
(though could be clarified by describing what kind of entities they are)

Included a few FIXMEs in tests where some further improvements could be
made.

TargetInfo::getSuitableAlign() was introduced in r146762 and is defined

Introduce __ALIGNOF_MAX_ALIGN_T__ which exposes getSuitableAlign() so
that libc++ may take advantage of it.

template parameters, don't look for parameters of outer templates. If a problem
is found in a default template argument, point the diagnostic at the partial
specialization (with a note pointing at the default argument) instead of
pointing it at the default argument and leaving it unclear which partial
specialization os problematic.

John McCall 57420b320c type_info objects are not unnamed_addr: the ABI requires us to
unique them and permits the implementation of dynamic_cast (and

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.

Richard Smith c7fb225cdc PR16638, DR1552: the exception specification on an implicitly-declared
'operator delete' or 'operator delete[]' is an explicit exception
specification. Therefore we should diagnose 'void operator delete(void*)'
instead of 'void operator delete(void*) noexcept'.

This diagnostic remains an ExtWarn, since in practice people don't always
include the exception specification in such a declaration.
