Fixed set-but-not-used warnings.

No intended functionality change.

This sadly doesn't have a test for the final
output because llvm-objdump can't dump relocations
that don't belong to a section :(

The style guide only forbids this for function declarations. So,
now

someFunction(
    aaaaaaaaaaaaaaaaaaaa, aaaaaaaaaaaaaaaaa, aaaaaaaaaaaa);

Is allowed in Chromium mode.

llvm-svn: 173806

It needs to be compatible with C++03.

Don't touch I->first on the end iterator, I == E!

Fix a crash in OpenCL code by using the proper (RHS) bit-width.

llvm-svn: 173802

This is
a) More efficient.
b) Important as we move forward with further metrics for penalty.

No functional changes intended.

llvm-svn: 173801

Moved everything users are not supposed to use to a private interface header.
Documented all public interfaces. Made them safe to use even if built without
MemorySanitizer.

Not all changes might be ideal, but IMO all are acceptable.

llvm-svn: 173793

Before:
  SomeType aaaaaaaaaaaaaaaaa = aaaaaa->aaaaaaaaaaaaaaaaa(),
      aaaaaaaaaaa = aaaaaa->aaaaaaaaaaa();
After:
  SomeType aaaaaaaaaaaaaaaaa = aaaaaa->aaaaaaaaaaaaaaaaa(),
           aaaaaaaaaaa = aaaaaa->aaaaaaaaaaa();

Add a diagnostic for an OpenCL kernel with a pointer pointer argument.
Also refactor the surrounding code a little.

llvm-svn: 173791

llvm-svn: 173790

C++11 allows that.

llvm-svn: 173789

the diagnostic's warn_ name. Switch some places (notably C++11 attributes)
which really wanted an error over to a different diagnostic. Finally, suppress
the diagnostic entirely for __ptr32, __ptr64 and __w64, to avoid producing
diagnostics in important system headers.

llvm-svn: 173788

This needs some more thinking, e.g. for namespaces, chains of if-else
if, ...

llvm-svn: 173787

llvm-svn: 173786

Those empty lines waste vertical whitespace and almost never
increase readability.

Before:
void f() {
  DoSomething();

}

After:
void f() {
  DoSomething();
}

The ARM and Thumb variants of LDREXD and STREXD have different constraints and
take different operands. Previously the code expanding atomic operations didn't
take this into account and asserted in Thumb mode.

[ASan] fix deallocation hook in allocator2: according to specification, dealloc hook should be called before deallocating memory
