This change adds the "-O binary" flag which directs llvm-objcopy to
output the object file to the same format as GNU objcopy does when given
the flag "-O binary". This was done by splitting the Object class into
two subclasses ObjectELF and ObjectBianry which each output a different
format but relay on the same code to read in the Object in Object.

Summary:
Last one of the `pvalloc` overflow checks!

`CheckForPvallocOverflow` was introduced with D35818 to detect when `pvalloc`
would wrap when rounding up to the next multiple of the page size.

Add this check to ASan's `pvalloc` implementation.

Summary:
This adds NetBSD specific:
 - ReadProcMaps()
 - MemoryMappingLayout::Next()

This code is largely shared with FreeBSD.

Part of the code inspired by the original work on libsanitizer in GCC 5.4 by Christos Zoulas.

Its sole purpose was to avoid spreading around ifdefs related to
building global-isel. Since r309990, GlobalISel is not optional anymore,
thus, we can get rid of this mechanism all together.

Summary:
The regular expression to match STL allocators can't easily account for
C++ mangling compression and fails to match some valid instances of STL
allocators. Perform this logic in clang instead.

Arguments, passed to the outlined function, must have correct address
space info for proper Debug info support. Patch sets global address
space for arguments that are mapped and passed by reference.

Also, cuda-gdb does not handle reference types correctly, so reference
arguments are represented as pointers.

llvm-svn: 310099

llvm-svn: 310098

Summary:
Previously, STL allocators were blacklisted in compiler_rt's
cfi_blacklist.txt because they mandated a cast from void* to T* before
object initialization completed. This change moves that logic into the
front end because C++ name mangling supports a substitution compression
mechanism for symbols that makes it difficult to blacklist the mangled
symbol for allocate() using a regular expression.

HasDeclarationMatcher did not handle DeducedType, it always returned false for deduced types.

So with code like this:
struct X{};
auto x = X{};

This did no longer match:
varDecl(hasType(recordDecl(hasName("X"))))

Because HasDeclarationMatcher didn't resolve the DeducedType of x.

This adds support for the main 128-bit atomic operations,
using the SystemZ instructions LPQ, STPQ, and CDSG.

Generating these instructions is a bit more complex than usual
since the i128 type is not legal for the back-end.  Therefore,
we have to hook the LowerOperationWrapper and ReplaceNodeResults
TargetLowering callbacks.

llvm-svn: 310094

We currently emit a serialization operation (bcr 14, 0) before every
atomic load and after every atomic store.  This is overly conservative.
The SystemZ architecture actually does not require any serialization
for atomic loads, and a serialization after an atomic store only if
we need to enforce sequential consistency.  This is what other compilers
for the platform implement as well.

Summary:
The bug was uncovered after fix of  PR23384 (part 3 of 3).
