[PPC64] Fix PR20071 (fctiduz generated for targets lacking that
instruction)
PR20071 identifies a problem in PowerPC's fast-isel implementation
for floating-point conversion to integer. The fctiduz instruction
was added in Power ISA 2.06 (i.e., Power7 and later). However, this
instruction is being generated regardless of which 64-bit PowerPC
target is selected.
The intent is for fast-isel to punt to DAG selection when this
instruction is not available. This patch implements that change.
For testing purposes, the existing fast-isel-conversion.ll test adds
a RUN line for -mcpu=970 and tests for the expected code generation.
Additionally, the existing test fast-isel-conversion-p5.ll was found
to be incorrectly expecting the unavailable instruction to be
generated. I've removed these test variants since we have adequate
coverage in fast-isel-conversion.ll.
This is needed to compile clang with debug+asserts on older powerpc64
and ppc970 targets.

We previously sent SIGKILL to the debuggee in DoDestroy, but did not
actually detach or kill via ptrace. It seems that this somehow didn't
matter on Linux, but did on FreeBSD.
This would happen when quitting LLDB while stopped at a breakpoint, for
example. The debuggee remained stopped in ptrace (with the signal
either pending or lost). After a timeout of a second or two LLDB exits,
which caused the debuggee to resume and dump core from an unhandled
SIGTRAP.
BringProcessIntoLimbo is a poorly named wrapper for ptrace(PT_KILL)

armv6hf targets the VFP variant of the ARM EABI and our copy of gcc is too

* WITHOUT_GCC

In addition, without an external toolchain, the following need to be left

* WITH_CLANG

As there is a different method of passing float and double values to
functions the ABI is incompatible with existing armv6 binaries. To use
this a full rebuild of world is required. Because no floating point values
are passed into the kernel an armv6 kernel with VFP enabled will work with

The combination of inline asm, stack realignment, and dynamic allocas

enough to trigger the check.

In X86SelectionDagInfo::EmitTargetCodeForMemcpy we check with MachineFrameInfo

emit rep movs (which clobbers esi).
The problem is that MachineFrameInfo wouldn't know about dynamic allocas or
inline asm that clobbers the stack pointer until SelectionDAGBuilder has
encountered them.
This patch fixes the problem by checking for such things when building the
FunctionLoweringInfo.

Fix a crash that occurs when PWD is invalid.
MCJIT needs to be able to run in hostile environments, even when PWD
is invalid. There's no need to crash MCJIT in this case.
The obvious fix is to simply leave MCContext's CompilationDir empty
when PWD can't be determined. This way, MCJIT clients,
and other clients that link with LLVM don't need a valid working directory.
If we do want to guarantee valid CompilationDir, that should be done
only for clients of getCompilationDir(). This is as simple as checking
for an empty string.
The only current use of getCompilationDir is EmitGenDwarfInfo, which
won't conceivably run with an invalid working dir. However, in the
purely hypothetically and untestable case that this happens, the
AT_comp_dir will be omitted from the compilation_unit DIE.
This should help fix assertions occurring with ports-mgmt/tinderbox,
when it is using jails, and sometimes invalidates clang's current

Block objects [1] are a C-level syntactic and runtime feature. They
are similar to standard C functions, but in addition to executable
code they may also contain variable bindings to automatic (stack)
or managed (heap) memory. A block can therefore maintain a set of
state (data) that it can use to impact behavior when executed.
This port is based on Apple's GCC 5646 with some bugfixes from
Apple GCC 5666.3. It has some small differences with the support
in clang, which remains the recommended compiler.
Perhaps the most notable difference is that in GCC that __block
is not actually a keyword, but a macro. There will be workaround
for this issue in a near future. Other issues can be consulted in
the clang documentation [2]

we are taking the code directly from Apple. To make this clearer we
are preserving the annoying "APPLE LOCAL" tags and the ChangeLogs
when they are available.

X86: cvtpi2ps is just an SSE instruction with MMX operands. It has no AVX
equivalent.
Give it the right register format so we can also emit it when AVX is enabled.
This should fix a "Cannot select: intrinsic %llvm.x86.sse.cvtpi2ps" fatal error
in clang while building the gnuradio port for amd64.

Fixes GCC libstdc++/29286
The fix seems to work for amd64 but causes segfaults on powerpc.
At this time gcc is much more important on powerpc than on amd64.

GCC 4.2 and previous have always warned about
"No newline at end of file".
Upstream GCC removed the warning completely but
Apple made it an optional warning. Adopt it for
compatibility with older GCC and clang.
While here, add comment to complement r258712.

The stdtime sources were moved from lib/libc to contrib/tzcode, and tzfile.h
is not an installed header, so the man page refers to its location in the
source tree.
The documentation could be more clear about the internal nature of the
header, but those changes should go through upstream tzcode.

following builtin functions:
* __builtin_ia32_pslldi128() takes __v4si instead of __v8hi
* __builtin_ia32_psllqi128() takes __v2di instead of __v8hi
* __builtin_ia32_psradi128() takes __v4si instead of __v8hi
This should fix the following errors when building the LINT kernel with

CodeGen: Don't emit linkage on thunks that aren't emitted because they're

This can happen when we're trying to emit a thunk with available_externally
linkage with optimization enabled but bail because it doesn't make sense for
vararg functions.

Move the body of GCCInstallationDetector ctor into an init() function
and call it from its only user. The linux toolchain. This saves quite
a lot of directory searching on other platforms.
See http://docs.freebsd.org/cgi/mid.cgi?51E6FAF5.3080802 for the
original discussion. With this fix, the search for gcc installations is
completely eliminated on FreeBSD.

On FreeBSD lldb sometimes reloads the the main module's (executable's)
symbols at the wrong address. Work around this for now by explicitly
reloading at base_address=0 when it happens.
A proper fix is needed but early testers have reported this issue so
this workaround should allow them to make further progress.

location for the native amd64 ABI. This fixes unwinding over the
signal frame after trampoline was moved to the shared page.
The code would be more correct if using sysctl for the target process
instead of inspecting gdb' own trampoline, but the current change is
least intrusive and currently, we always initialize the native ABI
sysvec first, which means that trampoline location for FreeBSD/amd64
ABI is relatively stable.
Similar change will benefit libunwind.

Among other causes, when gcc throws a warning before parsing any tokens,
the cur_token pointer is at the beginning of malloc'd memory.
Dereferencing cur_token[-1] can cause a segfault.

gcc: Move conditions before an assert.
It is a bit cleaner to check the conditions before calling the assertion.
It also preserves the style from the rest of the code.
This is just a cosmetical change to match better what both Apple's gcc42
and Android's gcc-4.2.1 do.
Google released and enhanced version of gcc-4.2.1 plus their local
patches for Android[1].
The patches are owned by Google and the license hasn't been changed
from the original GPLv2. We are only bringing a subset of the
available patches that may be helpful in FreeBSD. Changes specific
to android are not included.
