Add separate patch files for all the customizations we have currently

applied to our copy of llvm/clang.  These can be applied in alphabetical
order to a pristine llvm/clang 3.4 release source tree, to result in the
same version used in FreeBSD.

This is intended to clearly document all the changes until now, which
mostly consist of cherry pickings from the respective upstream trunks,
plus a number of hand-written FreeBSD-specific ones.  Hopefully those
can eventually be cleaned up and sent upstream too.

This is a set of individual patches, which contain all the customizations to
llvm/clang currently in the FreeBSD base system. These can be applied in
alphabetical order to a pristine llvm/clang 3.4 release source tree, for example
by doing:
svn co https://llvm.org/svn/llvm-project/llvm/tags/RELEASE_34/final llvm-3.4-final
svn co https://llvm.org/svn/llvm-project/cfe/tags/RELEASE_34/final llvm-3.4-final/tools/clang
cd llvm-3.4-final
for p in /usr/src/contrib/llvm/patches/patch-*.diff; do
patch -p0 -f -F0 -E -i $p -s || break
done
A number of these consist of hand-written modifications, specifically for
FreeBSD, while most others are cherry pickings off the llvm and clang trunks.
When a new version of llvm/clang is eventually imported, those latter ones will
largely disappear.

Pull in r200899 from upstream clang trunk (by Serge Pavlov):
Allow transformation of VariableArray to ConstantArray.
In the following code:
struct A { static const int sz; };
template<class T> void f() { T arr[A::sz]; }
the array 'arr' is represented as a variable size array in the template.
If 'A::sz' gets value below in the translation unit, the array in
instantiation can turn into constant size array.
This change fixes PR18633.

Pull in r195391 from upstream llvm trunk (by Eric Christopher):
In Dwarf 3 (and Dwarf 2) attributes whose value are offsets into a
section use the form DW_FORM_data4 whilst in Dwarf 4 and later they
use the form DW_FORM_sec_offset.
This patch updates the places where such attributes are generated to
use the appropriate form depending on the Dwarf version. The DIE entries
affected have the following tags:
DW_AT_stmt_list, DW_AT_ranges, DW_AT_location, DW_AT_GNU_pubnames,
DW_AT_GNU_pubtypes, DW_AT_GNU_addr_base, DW_AT_GNU_ranges_base
It also adds a hidden command line option "--dwarf-version=<uint>"
to llc which allows the version of Dwarf to be generated to override
what is specified in the metadata; this makes it possible to update
existing tests to check the debugging information generated for both
Dwarf 4 (the default) and Dwarf 3 using the same metadata.
Patch (slightly modified) by Keith Walker!
Introduced here: http://svn.freebsd.org/changeset/base/261991

Revert "Reverting r193835 due to weirdness with Go..."
The cgo problem was that it wants dwarf2 which doesn't support direct
constant encoding of the location. So let's add support for dwarf2
encoding (using a location expression) of data member locations.
This reverts commit r198385.

Pull in r199028 from upstream llvm trunk (by Jakob Stoklund Olesen):
The SPARCv9 ABI returns a float in %f0.
This is different from the argument passing convention which puts the
first float argument in %f1.
With this patch, all returned floats are treated as if the 'inreg' flag
were set. This means multiple float return values get packed in %f0,
%f1, %f2, ...
Note that when returning a struct in registers, clang will set the
'inreg' flag on the return value, so that behavior is unchanged. This
also happens when returning a float _Complex.

Pull in r199061 from upstream llvm trunk (by Jakob Stoklund Olesen):
Handle bundled terminators in isBlockOnlyReachableByFallthrough.
Targets like SPARC and MIPS have delay slots and normally bundle the
delay slot instruction with the corresponding terminator.
Teach isBlockOnlyReachableByFallthrough to find any MBB operands on
bundled terminators so SPARC doesn't need to specialize this function.
Introduced here: http://svn.freebsd.org/changeset/base/262261

Pull in r199186 from upstream llvm trunk (by Jakob Stoklund Olesen):
Switch the NEON register class from QPR to DPair.
The already allocatable DPair superclass contains odd-even D register
pair in addition to the even-odd pairs in the QPR register class. There
is no reason to constrain the set of D register pairs that can be used
for NEON values. Any NEON instructions that require a Q register will
automatically constrain the register class to QPR.
The allocation order for DPair begins with the QPR registers, so
register allocation is unlikely to change much.

Pull in r199187 from upstream llvm trunk (by Jakob Stoklund Olesen):
Always let value types influence register classes.
When creating a virtual register for a def, the value type should be
used to pick the register class. If we only use the register class
constraint on the instruction, we might pick a too large register class.
Some registers can store values of different sizes. For example, the x86
xmm registers can hold f32, f64, and 128-bit vectors. The three
different value sizes are represented by register classes with identical
register sets: FR32, FR64, and VR128. These register classes have
different spill slot sizes, so it is important to use the right one.
The register class constraint on an instruction doesn't necessarily care
about the size of the value its defining. The value type determines
that.
This fixes a problem where InstrEmitter was picking 32-bit register
classes for 64-bit values on SPARC.

Pull in r200373 from upstream llvm trunk (by Venkatraman Govindaraju):
[Sparc] Use %r_disp32 for pc_rel entries in gcc_except_table and eh_frame.
Otherwise, assembler (gas) fails to assemble them with error message "operation
combines symbols in different segments". This is because MC computes
pc_rel entries with subtract expression between labels from different sections.

Pull in r196874 from upstream llvm trunk (by Andrew Trick):
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?\226?\128?\153t 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?\226?\128?\153t 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.

Pull in r196986 from upstream llvm trunk (by Reid Kleckner):
Revert the backend fatal error from r196939
The combination of inline asm, stack realignment, and dynamic allocas
turns out to be too common to reject out of hand.
ASan inserts empy inline asm fragments and uses aligned allocas.
Compiling any trivial function containing a dynamic alloca with ASan is
enough to trigger the check.
XFAIL the test cases that would be miscompiled and add one that uses the
relevant functionality.

Pull in r202930 from upstream llvm trunk (by Hans Wennborg):
Check for dynamic allocas and inline asm that clobbers sp before building
selection dag (PR19012)
In X86SelectionDagInfo::EmitTargetCodeForMemcpy we check with MachineFrameInfo
to make sure that ESI isn't used as a base pointer register before we choose to
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.

Pull in r203311 from upstream llvm trunk (by Arnold Schwaighofer):
ISel: Make VSELECT selection terminate in cases where the condition type has to
be split and the result type widened.
When the condition of a vselect has to be split it makes no sense widening the
vselect and thereby widening the condition. We end up in an endless loop of
widening (vselect result type) and splitting (condition mask type) doing this.
Instead, split both the condition and the vselect and widen the result.
I ran this over the test suite with i686 and mattr=+sse and saw no regressions.
Fixes PR18036.
