Oren Ben Simhon c0f073b67f [X86] RegCall - Handling long double arguments
The change is part of RegCall calling convention support for LLVM.
Long double (f80) requires special treatment as the first f80 parameter is saved in FP0 (floating point stack).
This review present the change and the corresponding tests.

Serge Pavlov f258ff1fa9 Fix file name resolution in nested response files
If a response file in construct `@file` was specified by relative name,
constructs `@file` nested within it were resolved incorrectly if the
flag RelativeNames in call to ExpandResponseFile was set to true.

respective change (see D24933).

Also this patch uses file-scope functions instead of class member function.

Now that ICF class is not visible from outside, InputSection class
can no longer be "friend" of it. So I removed the friend relation
and just make it expose the features to public.

Saleem Abdulrasool b14fc390dc ExceptionDemo: remove some undefined behaviour
The casting based reading of the LSDA could attempt to read unsuitably aligned
data.  Avoid that case by explicitly using a memcpy.  A similar approach is used
in libc++abi to address the same UB.

Saleem Abdulrasool c0e4e7d990 ExceptionDemo: prefer headers over redeclarations
Rather than redeclaring the interfaces for exceptions, prefer using the
`unwind.h` header.  This is vended by at least gcc and clang, and can also be
found by an external unwinding library (e.g. libunwind).  Doing this simplifies
the example to the exception handling itself.  Minor tweaks are the result of
_Unwind_Context_t not being defined, which is just a typedef for struct
_Unwind_Context *.  NFC.

Alexei Starovoitov e6ddac0def [bpf] add BPF disassembler
add BPF disassembler, so tools like llvm-objdump can be used:
$ llvm-objdump -d -no-show-raw-insn ./sockex1_kern.o

./sockex1_kern.o:	file format ELF64-BPF

Disassembly of section socket1:
bpf_prog1:
       0:	r6 = r1
       8:	r0 = *(u8 *)skb[23]
      10:	*(u32 *)(r10 - 4) = r0
      18:	r1 = *(u32 *)(r6 + 4)
      20:	if r1 != 4 goto 8
      28:	r2 = r10
      30:	r2 += -4

ld_imm64 (the only 16-byte insn) and special ld_abs/ld_ind instructions
had to be treated in a special way. The decoders for the rest of the insns
are automatically generated.

Add tests to cover new functionality.

This code is taken from public domain.

I wrote a sha1 command and ran it on my Xeon E5-2680 v2 2.80GHz machine.
Here is a result. The new hash function is 37% faster than before.

Martin Storsjo 8c59680ac2 builtins: Allow building windows arm functions for mingw
When building with clang/LLVM in MSVC mode, the msvcrt libraries contain
these functions.

When building in a mingw environment, we need to provide them somehow,
e.g. via compiler-rt.

The aeabi divmod functions work in the same way as the corresponding
__rt_*div* functions for windows, but their parameters are swapped.
The functions for converting float to integer and vice versa are the
same as their aeabi equivalents, only with different function names.

Mehdi Amini fec2158292 [ThinLTO] Fix crash when importing an opaque type
It seems that because ThinLTO does not import the full module,
some invariant of the type mapper are broken.

In Monolithic LTO, we import every globals: when calling
IRLinker::copyFunctionProto() on @foo(), we end-up calling
TypeMapTy::get(FTy) on the type of @foo(), which will map
%0 and record the destination as opaque.

ThinLTO skips this because @foo is not imported and goes directly
to the next stage.

Next we call computeTypeMapping() that map the types for each
globals, and ends up checking for type isomorphism, and may add
type mapping. However it doesn't record if there was an opaque
destination type that was resolved.

Instead of lazily "discovering" opaque type in the destination
module on the go, we change the TypeFinder to eagerly record all
types and not only the named ones.
