Petar Jovanovic 1dbc317736 [Mips] Generate warning for invalid '-mnan' and '-march' combinations
This patch generates a warning for invalid combination of '-mnan' and
'-march' options, it properly sets NaN encoding for a given '-march',
and it passes a proper NaN encoding to the assembler.

Patch by Vladimir Radosavljevic.

Ulrich Weigand 881497ac29 [SystemZ] Fix definition of IntMaxType / Int64Type
Like on other 64-bit platforms, Int64Type should be SignedLong
on SystemZ, not SignedLongLong as per default.  This could cause
ABI incompatibilities in certain cases (e.g. name mangling).

Hal Finkel 0d0a1a53e3 [PowerPC] ABI support for the QPX vector instruction set
Support for the QPX vector instruction set, used on the IBM BG/Q supercomputer,
has recently been added to the LLVM PowerPC backend. This vector instruction
set requires some ABI modifications because the ABI on the BG/Q expects
<4 x double> vectors to be provided with 32-byte stack alignment, and to be
handled as native vector types (similar to how Altivec vectors are handled on
mainline PPC systems). I've named this ABI variant elfv1-qpx, have made this
the default ABI when QPX is supported, and have updated the ABI handling code
to provide QPX vectors with the correct stack alignment and associated
register-assignment logic.

Ed Schouten f33c607c0a Add target information for CloudABI on x86-64.
CloudABI can be identified by the __CloudABI__ preprocessor definition. The
system uses ELF executables.

CloudABI uses Unicode 7.0.0 for the encoding of wchar_t. As Unicode 7.0.0 is
synchronized with ISO/IEC 10646:2012 (released on 2012-06-01),
__STDC_ISO_10646__ is defined as 201206L.

Ed Schouten 4992099b42 Add C11 *_DECIMAL_DIG.
Before C11 there was only the DECIMAL_DIG definition. As of C11, we now
have one definition per floating point type (e.g. DBL_DECIMAL_DIG).
Change the existing code to define the new versions. To remain backward
compatible, define __DECIMAL_DIG__ as __LDBL_DECIMAL_DIG__.

Also update the tests. It seems that some of the existing test vectors
were incorrect. Change all tests for __DECIMAL_DIG__ to expect
__LDBL_DECIMAL_DIG__. Add tests for *_DECIMAL_DIG for FreeBSD/amd64, as
I happen to have such a system laying around. I've validated that the
values are in sync with <float.h>.

Vasileios Kalintiris ea50312b84 [mips] Partially revert r223927: Removing __SIZEOF_INT128__ macro for MIPS64
Partially revert r223927 because LLVM gained support for 128-bit integers

Tim Northover a6a19f1e38 Preprocessor: support __BIGGEST_ALIGNMENT__ macro
For compatibility with GCC (and because it's generally helpful information
otherwise inaccessible to the preprocessor). This appears to be canonically the
alignment of max_align_t (e.g. on i386, __BIGGEST_ALIGNMENT__ is 4 even though
vector types will be given greater alignment).

Simon Atanasyan d83248e60c [mips] Removing __SIZEOF_INT128__ macro for MIPS64
This is a temporary workaround while MIPS64 has not yet fully supported
128-bit integers. But declaration of int128 type is necessary even though
`__SIZEOF_INT128__` is undefined because c++ standard header files like
`limits` throw error message if `__int128` is not available.

Oliver Stannard 28ee5d2e90 [ARM] Change default ABI for AArch32 to be "aapcs" (was "apcs-gnu")
The current default abi when no environment is given is "apcs-gnu",
which is obsolete. This patch changes the default to "aapcs". "aapcs" has both
hard- and soft-float variants, so the -mhard-float, -msoft-float and
-mfloat-abi= options now all behave as expected when no environment is
specified in the triple.

While writing this I also noticed that a preprocessor test claims to be
checking darwin, but is actually checking the defaults, which are
different for darwin.

__INTx_TYPE__ directly without prefixing it with signed and to use
__UINTx_TYPE__ for unsigned ones.

The value of __INTx_TYPE__ now matches GCC.

Ulrich Weigand 8afad61a93 [PowerPC] Support ELFv1/ELFv2 ABI selection via -mabi= option
While Clang now supports both ELFv1 and ELFv2 ABIs, their use is currently
hard-coded via the target triple: powerpc64-linux is always ELFv1, while
powerpc64le-linux is always ELFv2.

These are of course the most common scenarios, but in principle it is
possible to support the ELFv2 ABI on big-endian or the ELFv1 ABI on
little-endian systems (and GCC does support that), and there are some
special use cases for that (e.g. certain Linux kernel versions could
only be built using ELFv1 on LE).

This patch implements the Clang side of supporting this, based on the
LLVM commit 214072.  The command line options -mabi=elfv1 or -mabi=elfv2
select the desired ABI if present.  (If not, Clang uses the same default
rules as now.)

Specifically, the patch implements the following changes based on the
presence of the -mabi= option:

In the driver:
- Pass the appropiate -target-abi flag to the back-end
- Select the correct dynamic loader version (/lib64/ld64.so.[12])

In the preprocessor:
- Define _CALL_ELF to the appropriate value (1 or 2)

In the compiler back-end:
- Select the correct ABI in TargetInfo.cpp
- Select the desired ABI for LLVM via feature (elfv1/elfv2)
