This test case was never actually testing the trivial spiller: the -spiller
option has not been hooked up for a while now.

add the code and test cases for 32-bit ARM symbolizer.
Also fixed the printing of data in code as it was not using the table correctly
and needed to fix one of the test cases too.
This will break lld’s test/mach-o/arm-interworking-movw.yaml till the tweak
for that is made. Which I’ll be committing immediately after this commit.

Imported declarations can be DIGlobalVariables which aren't a DIScope. Today
clang (unknowingly I believe) shoehorns these into a DIScope and it all works
just because we never access the fields.

reassociate floating-point instructions without the unsafe algebra flag.

Summary:
As with returns, we must be able to identify f128 arguments despite them
being lowered away. We do this with a pre-analyze step that builds a
vector and then we use this vector from the tablegen-erated code.

Summary:
Currently, we give an error if %z is used with non-immediates, instead of continuing as if the %z isn't there.
For example, you use the %z operand modifier along with the "Jr" constraints ("r" makes the operand a register, and "J" makes it an immediate, but only if its value is 0).
In this case, you want the compiler to print "$0" if the inline asm input operand turns out to be an immediate zero and you want it to print the register containing the operand, if it's not.
We give an error in the latter case, and we shouldn't (GCC also doesn't).

Summary:
Improved warning message when using .cpload inside a reorder section and added an error message for using .cpload with Mips16 enabled.
Modified the tests to fit with the changes mentioned above, added a test-case for the N32 ABI in cpload.s and did some reformatting to make the tests easier to read.

Summary:
Fixed all of the missing endian conversions that Lang Hames and I identified in
RuntimeDyldMachOARM.h.
Fixed the opcode emission in RuntimeDyldImpl::createStubFunction() for AArch64,
ARM, Mips when the host endian doesn't match the target endian.
PowerPC will need changing if it's opcodes are affected by endianness but I've
left this for now since I'm unsure if this is the case and it's the only path
that specifies the target endian.
This patch fixes MachO_ARM_PIC_relocations.s on a big-endian Mips host. This
is the last of the known issues on this host.

Use the position of the subsequent symbol in the object file to infer
the size of it's predecessor. I hope to eventually remove whatever COFF
specific details from this little algorithm so that we can unify this
logic with what Mach-O does.

When generating gcov compatible profiling, we sometimes skip emitting
data for functions for one reason or another. However, this was
emitting different function IDs in the .gcno and .gcda files, because
the .gcno case was using the loop index before skipping functions and
the .gcda the array index after. This resulted in completely invalid
gcov data.
This fixes the problem by making the .gcno loop track the ID
separately from the loop index.

condition to match a blend.
This prevents optimizations that work on VSELECT to perform invalid
transformations. Indeed, the optimized condition does not match the vector
boolean content that is expected and bad things may happen.
This patch yields the exact same code on the whole test-suite + specs (-O3 and
-O3 -march=core-avx2), it improves one test case (vector-blend.ll) and fixes a
bug reduced in vselect-avx.ll.

Added missing memory folding for the (V)CVTDQ2PS instructions - we can safely fold these (but not the (V)CVTDQ2PD versions which have a register/memory size discrepancy in the source operand). I've added a test case demonstrating that stack folding now works.

This works around the limitation that PTX does not allow .param space
loads/stores with arbitrary pointers.
If a function has a by-val struct ptr arg, say foo(%struct.x *byval %d), then
add the following instructions to the first basic block :
%temp = alloca %struct.x, align 8
%tt1 = bitcast %struct.x * %d to i8 *
%tt2 = llvm.nvvm.cvt.gen.to.param %tt2
%tempd = bitcast i8 addrspace(101) * to %struct.x addrspace(101) *
%tv = load %struct.x addrspace(101) * %tempd
store %struct.x %tv, %struct.x * %temp, align 8
The above code allocates some space in the stack and copies the incoming
struct from param space to local space. Then replace all occurences of %d
by %temp.
Fixes PR21465.

Change `NamedMDNode::getOperator()` from returning `MDNode *` to
returning `Value *`. To reduce boilerplate at some call sites, add a
`getOperatorAsMDNode()` for named metadata that's expected to only
return `MDNode` -- for now, that's everything, but debug node named
metadata (such as llvm.dbg.cu and llvm.dbg.sp) will soon change. This
is part of PR21433.
Note that there's a follow-up patch to clang for the API change.
