It wasn't possible for an anonymous type to show up inside of function arguments.
However, decltype (which MSVC added support for in 2010) makes this
possible. Further, backrefs to these anonymous types can now be formed.
This fixes PR18022.
N.B. We do not, and very likely _will not_, support MSVC's bug where
subsequent typedefs of anonymous types leak into the linkage name; this
is a gross violation of the ABI. A warning should be introduced to
inform our users of this particular shortcoming.

From Jim Ingham's email:
It does look like ThreadPlanStepInRange test is some kind of thinko.
In practice, in this case it is probably safe to run only one thread
when doing the "step through" since that generally involved running
from a shared library stub to its target. That could deadlock if the
dynamic loader has to fix up the symbol, and another thread is in the
middle of doing that. But that doesn't seem to be very common, or at
least the code is clearly wrong but I haven't had any reports of this
causing deadlocks...

Although ptrace() can be passed a PID or TID for PT_CONTINUE and PT_STEP,
the kernel operates on all threads in the process in both cases. (See
the FOREACH_THREAD_IN_PROC in FreeBSD's sys_process.c:kern_ptrace.)
Make this clear by using the PID from the ProcessMonitor instance.

These are handled almost identically to static mode (and ELF's global address
materialisation), except that a symbol may have "$non_lazy_ptr" appended. This
can be handled by passing appropriate flags along with the instruction instead
of using entirely separate pseudo-instructions.

These should not use COMDATs. GNU as uses .bss for .lcomm and section 0 for
.comm.
Given
static int a;
int b;
MSVC puts both in .bss. This patch then puts both .comm and .lcomm on .bss. With
this change we agree with gas on .lcomm, are much closer on .comm and clang-cl
matches msvc on the above example.

There is no sane way for an LEApcrel (= single ADR) instruction to generate a
global address on any ARM target I know of. Fortunately, no-one was trying to
any more, but there were vestigial patterns.

No longer allow interceptors to be called during initialization, use the preinit
array (instead of initializing at the first call to an intercepted function) and
adopt the calloc() hack from ASan.

Summary:
Implement TwoLevelByteMap and use it for the internal allocator on 64-bit.
This reduces bss on 64-bit by ~8Mb because we don't use FlatByteMap on 64-bits any more.
Dmitry, please check my understanding of atomics.

Summary:
Moved the requirement for SelectionDAG::getConstant() to return legally
typed nodes slightly earlier. There were two optional DAGCombine passes
that were missed out and were required to produce type-legal DAGs.
Simplified a code-path in tryFoldToZero() to use SelectionDAG::getConstant().
This provides support for both promoted and expanded vector types whereas the
previous code only supported promoted vector types.
Fixes a "Type for zero vector elements is not legal" assertion detected by
an llvm-stress generated test.

No functional changes intended. However, it seems to have found a buggy
behavior in one of the tests. I think this structure is generally
desirable and it will make a planned bugfix significantly easier.

This patch won't change the output because the layout of linker internal
atoms is forced by layout-{before,after} references. Ordinals of the linker
internal atoms are not currently used. (That's why it's working even if there
are atoms having the same ordinals.)
llvm-svn: 195610
Change the attribute from sectionBasedOnContent to sectionCustomRequired
because its the right attribute for atoms read from COFF files to have.
COFF atoms should basically be emitted to the section having the same name
as input. Permissions/attributes should not affect that.
There's no functionality change because the writer doesn't yet use the
section name. The writer will be modified in a following patch, so that atoms
are written to its customSectionName()'s section.

Looks like -L paths are not positional. They need to be added to a list of
search paths and those needs to be searched when lld looks for a library.

If /subsystem option is not specified, the linker needs to infer it from the
entry point function. If "main" or "wmain" is defined, it's a console
application. If "WinMain" or "wWinMain" is defined, it's a GUI application.

clang's attribute support is mature by now so replace Sean's warning and email
address with a standard LLVM copyright heading.
Also remove a personal email address and credit docstring from CGObjCGNU that
shouldn't have been there.
This is in line with the LLVM developer policy introduced in r45410.
Contributors can add themselves to CREDITS.txt while active module owners are
listed in CODE_OWNERS.TXT.

Clang still has support for running gcc for performing various stages
of a build. Right now it looks like this is used for
* Supporting Fortran in the clang driver
* Running an assembler or linker in systems we don't yet know how to
run them directly.
It looks like the gcc::Precompile is a vestige from the days when we
supported using clang for C and running gcc for c++. This patch removes it
(yes, we have no tests for it).
llvm-svn: 195586
This is currently unused by any test. The code path would still be hit
by clang on ppc, but
* PPC has not been supported on current versions of OS X
* A port of current clang to older OS X on ppc should be using
toolchains::DarwinClang.
