The parameter definition of this API is const volatile __int64*, but it is not defined correctly in clang. Move the 'CD' to the correct location.

Patch by Daniel Jump!
llvm-svn: 228678
Somehow a check for aarch64 was added to the Darwin toolchain's
isKernelStatic function as part of the initial commit for Apple's
arm64 target (r205100). That check was not in any of Apple's internal
code and no one here knows where it came from. It has been harmless
because "-static" does not change much, if anything, for arm64 iOS code,
but it makes no sense to keep this check.

already have, check whether the name from the module is actually newer than the
existing declaration. If it isn't, we might (say) replace a visible declaration
with an injected friend, and thus make it invisible (or lose a default argument
or an array bound).

Don't assume it will provide an error or null-terminate the string on
truncation, since POSIX doesn't guarantee either behaviour (although
Linux and Darwin at least will do the 'right thing').
llvm-svn: 228613
If the lock file manager times out, we should give an error rather than
silently trying to load the existing module. And delete the
(presumably) dead lock file, since it will otherwise prevent progress in
future invokations. This is unsound since we have no way to prove that
the lock file we are deleting is the same one we timed out on, but since
the lock is only to avoid excessive rebuilding anyway it should be okay.
Depends on llvm r228603.
llvm-svn: 228604
If gethostname() is not successful, just skip adding the hostname to the
module hash. And don't bother setting hostname[255] = 0, since if
gethostname() is successful, it will be null-terminated already (and if
it's not successful we don't read the string now.
llvm-svn: 228601
Matches the existing code for scalar default arguments. Complex default
arguments probably need the same handling too (test/fix to that coming
next).

Still yellow because 3.6 is unreleased. While there make Urbana paper
links clickable and list binary literals as available in Clang 2.9
(they've been available basically since the dawn of Clang, but not
having a version number in the table looks weird)
llvm-svn: 228571
We'd give the VarDecl a CXXConstructExpr even though it is annotated
with an alias attribute. This would make us trip over sanity checking
asserts.
This fixes PR22493.
llvm-svn: 228523
This prevents contracting:
auto lambda = []() {
int a = 2
#if A
+ 2
#endif
;
};
into:
auto lambda = []() { int a = 2
#if A + 2
#endif ; };
Which is obviously BAD.
This fixes llvm.org/PR22496.

It's slightly cheaper than copying it, if the DebugLoc points to replaceable
metadata every copy is recorded in a DenseMap, moving reduces the peak size of
that map.

so we merge them based on their position within the surrounding context.

Before:
@try {
// ...
}
@finally {
// ...
}
Now:
@try {
// ...
} @finally {
// ...
}
This is consistent with how we format C++ try blocks and SEH try blocks.
clang-format not doing this before was an implementation oversight.
This is dependent on BraceBreakingStyle. The snippet above is with the
Attach style. Style Stroustrip for example still results in the "Before:"
snippet, which makes sense since other blocks (try, else) break after '}' too.

Also removed unused builtins.

If you request that the file manager not close your file immediately
after reading, it's useful to be able to close it later to prevent a
file descriptor leak.

This reverts commit r228382.
This breaks the following case: Reported by Jeroen Ketema:
http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-20150202/122961.html
typedef __attribute__((ext_vector_type(3))) char char3;
void foo() {
char3 v = {1,1,1};
char3 w = {1,2,3};
w <<= v;
}
If I compile with:
clang -x cl file.c
Then an error is produced:
file.c:10:5: error: expression is not assignable
w <<= v;
~ ^
1 error generated.

This patch adds an extra test case to clang-exception-flags.cpp.
No functional change intended.

Introduce a number of checks:
1. If LHS is a scalar, then RHS cannot be a vector.
2. Operands must be of integer type.
3. If both are vectors, then the number of elements must match.
Relax the requirement for "usual arithmetic conversions":
When LHS is a vector, a scalar RHS can simply be expanded into a
vector; OpenCL does not require that its rank be lower than the LHS.
For example, the following code is not an error even if the implicit
type of the constant literal is "int".
char2 foo(char2 v) { return v << 1; }
Consolidate existing tests under CodeGenOpenCL, and add more tests
under SemaOpenCL.

of that entity, ensure that the redeclaration chain is reordered properly on
reload. Otherwise, the result of name lookup for that entity may point to an
entity that is too old; if that's an injected friend name or the like, that
can result in the name not being found at all.

For compatibility with GCC (and because it's generally helpful information
otherwise inaccessible to the preprocessor). This appears to be canonically the
alignment of max_align_t (e.g. on i386, __BIGGEST_ALIGNMENT__ is 4 even though
vector types will be given greater alignment).

After r228258, Clang started emitting C++ EH IR that LLVM wasn't ready
to deal with, even when exceptions were disabled with /EHs-. This time,
make /EHs- turn off -fexceptions while still emitting exceptional
constructs in functions using __try. Since Sema rejects C++ exception
handling constructs before CodeGen, landingpads should only appear in
such functions as the result of a __try.

perform *non-list* initialization of the entity from x, but create a

Plus some fixes to ensure we mangle correctly in this and related cases.

It caused a chromium base unittest that tests throwing and catching SEH
exceptions to fail (http://crbug.com/455488) and I suspect it might also
be the cause of the chromium clang win 64-bit shared release builder timing
out during compiles. So revert to see if that's true.

In r227480, Ulrich Weigand introduced a workaround for a linker
optimization bug that can create mis-optimized code for accesses to
general-dynamic or local-dynamic TLS variables. The linker
optimization bug only occurred for Clang/LLVM because of some
inefficient code being generated for these TLS accesses. I have
recently corrected LLVM to produce the efficient code sequence
expected by the linkers, so this workaround is no longer needed.
Therefore this patch reverts r227480.
I've tested that the previous bootstrap failure no longer occurs with
the workaround reverted.

The analyzer thinks that ArraySubscriptExpr cannot be an r-value (ever).
However, it can be in some corner cases. Specifically, C forbids expressions
of unqualified void type from being l-values.
Note, the analyzer will keep modeling the subscript expr as an l-value. The
analyzer should be treating void* as a char array
(https://gcc.gnu.org/onlinedocs/gcc-4.3.0/gcc/Pointer-Arith.html).
