This patch adds -f64:32:64 to 32 bit ppc darwin since a f64 inside a
structure are only 32 bit aligned.
The patch also drop -f128:64:128 from all ppc darwin, since f128 is
128 bit aligned.

This code is not robust enough and triggers when simply linking with
libdynamorio.so, without any code translation at all. Disabling it is safe
(i.e. we may unpoison too much memory and see false negatives, but never false
positives).

We now report the following:
$ polly-clang -O3 -mllvm -polly -mllvm -polly-report test.c -c \
-gline-tables-only
note: Polly detected an optimizable loop region (scop) in function 'foo'
test.c:2: Start of scop
test.c:3: End of scop

Before:
aaaaaaaaaa(aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa(
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa)
.aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa);
aaaaaaaaaa = aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa(
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa)
.aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa();
After:
aaaaaaaaaa(aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa(
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa)
.aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa);
aaaaaaaaaa = aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa(
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa)
.aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa();
Probably still not ideal, but should be a step into the right direction.

Clang sets the float-abi target option manually, but no longer
annotates each function with its ABI. This can lead to confusing
mistmatch between "clang -emit-llvm | llc" and normal clang
invocations.
Besides which, gnueabihf actually *is* hard-float. Defaulting to soft
was just perverse.

Right now clang produces the same DataLayout for all of them, but it could, for
example, add 'n' specifications when the end architecture is given.
No functionality change, this should just make future changes easier to read.

The .end directive indicates the end of the file. No further instructions are
processed after a .end directive is encountered.
One potential (glaringly obvious) optimisation that could be pursued here is to
extend MCAsmParser with a DiscardRemainder method to avoid processing lexemes to
the end of the file. It was unclear at this point if that would be worth
adding, and could easily be added in a follow on change.

This simplifies type unit and type unit reference creation as well as
setting the stage for inter-type hashing across type unit boundaries.

This has no functionality change as clang adds explicit alignment info for
byval arguments. The only difference is that now the clang produced
DataLayout string for AArch64 is identical to the LLVM produced one.

The instruction definitions in the PPC backend have a number of variants
defined for the same instruction to represent differences between 64-bit and
32-bit semantics. In order to generate a disassembler for the PPC backend, we
need to mark all but one of these as CodeGen only.
No functionality change intended; this is prep work for PPC disassembly
support.
llvm-svn: 197535
The convention used to specify the PowerPC ISA is that bits are numbered in
reverse order (0 is the index of the high bit). To support this "little endian"
encoding convention, CodeEmitterGen will reverse the bit numberings prior to
generating the encoding tables. In order to generate a disassembler,
FixedLenDecoderEmitter needs to do the same.
This moves the bit reversal logic out of CodeEmitterGen and into CodeGenTarget
(where it can be used by both CodeEmitterGen and FixedLenDecoderEmitter). This
is prep work for disassembly support in the PPC backend (which is the only
in-tree user of this little-endian encoding support).
llvm-svn: 197532
Without this, assembling clang's disassembly would produce an object
file with the IMAGE_SCN_CNT_INITIALIZED_DATA section characteristic
rather than the uninitialized one. link.exe would warn when merging
comdats with different flags.

This is in preparation for landing an implementation of unw_getcontext
on a system where it's mangled 'unw_getcontext', not '_unw_getcontext'.

Unlike Itanium's VTTs, the 'most derived' boolean or bitfield is the
last parameter for non-variadic constructors, rather than the second.
For variadic constructors, the 'most derived' parameter comes after the
'this' parameter. This affects constructor calls and constructor decls
in a variety of places.
