Allocas marked inalloca are never static, but we were trying to put them
into the static alloca map if they were in the entry block.  Also add an
assertion in x86 fastisel.

The code path it was guarding was already using emitRawComment.

To remove this one simply move the end of file logic from the asm printer to
the target mc streamer.

This removes the last call to hasRawTextSupport from lib/Target.

llvm-svn: 200590

The target machine type affects the meaning of other options, in particular
how to mangle symbols. So we want to handle the option first and then parse
all the other options.

This fixes PR15768, where the sret parameter and the 'this' parameter
are in the wrong order.

Instance methods compiled by MSVC never return records in registers,
they always return indirectly through an sret pointer.  That sret
pointer always comes after the 'this' parameter, for both __cdecl and
__thiscall methods.

Unfortunately, the same is true for other calling conventions, so we'll
have to change the overall approach here relatively soon.

With this change, we give different results for __alignof than MSVC, but
our record layout is compatible.

Some data member pointers also now have a size that is not a multiple of
their alignment.

Fixes PR18618.

There is nothing wrong with printing the disassembly section when printing
text. An hypothetical assembler would then produce a .o just like our
direct object emission produces.

It looks like these pseudos were only used for pattern matching. Def pats are
the appropriate way to do that. As a bonus, these intrinsics will now have
memory operands folded properly, and better FMA3 variants selected where
appropriate (see r199933).

transform accordingly. Based on similar code from Loop vectorization.
Subsequent commits will include vectorization of function calls to
vector intrinsics and form function calls to vector library calls.

have to check valid forms before deciding whether or not we're going
to hash which will let the default be to return without doing anything.

This ensures DWARF consumers don't confuse these references for
definitions. I'd argue it might be nice to improve debuggers so we don't
need this, but it's just one field in an abbreviation anyway - so it
doesn't seem worth the fight.

The two identical implementations of __cpuid for X86 / X86_64 were

Some build environments are missing the required headers.
This reverts r200544, r200547, r200551. This does not revert the change that
introduced READWRITE ioctl type.

Oh sorry, I missed LTO.exports, ... I checked just only *.cpp(s).

MSVC always places the 'this' parameter for a method first.  The
implicit 'sret' pointer for methods always comes second.  We already
implement this for __thiscall by putting sret parameters on the stack,
but __cdecl methods require putting both parameters on the stack in
opposite order.

Using a special calling convention allows frontends to keep the sret
parameter first, which avoids breaking lots of assumptions in LLVM and
Clang.

Fixes PR15768 with the corresponding change in Clang.
