files that have dubious fixes reverted.)

llvm-svn: 329399
Summary:
This patch extend getTargetDefines and implement handleTargetFeatures
and hasFeature. and define corresponding marco for those features.

The diagnostic system for Clang can already handle many AST nodes. Instead
of converting them to strings first, just hand the AST node directly to
the diagnostic system and let it handle the output. Minor changes in some
diagnostic output.

This allows users to turn off warnings about this pragma specifically,
while still receiving warnings about other ignored pragmas.

This is a partial recommit of r327189 that was reverted
due to test issues. I.e., this recommits minimal functional
change, the FP16 feature test macros, and adds tests that
were missing in the original commit.
llvm-svn: 327455
Summary:
If the flag -fforce-enable-int128 is passed, it will enable support for __int128_t and __uint128_t types.
This flag can then be used to build compiler-rt for RISCV32.

Cannon Lake does not support CLWB, therefore it
does not include all features listed under SKX.
Patch by Gabor Buella
Differential Revision: https://reviews.llvm.org/D43459
llvm-svn: 325655
To be compatible with GCC if soft floating point is in effect any FPU
specified is effectively ignored, eg,
-mfloat-abi=soft -fpu=neon
If any floating point features which require FPU hardware are enabled
they must be disable.
There was some support for doing this for NEON, but it did not handle
VFP, nor did it prevent the backend from emitting the build attribute
Tag_FP_arch describing the generated code as using the floating point
hardware if a FPU was specified (even though soft float does not use
the FPU).
Disabling the hardware floating point features for targets which are
compiling for soft float has meant that some tests which were incorrectly
checking for hardware support also needed to be updated. In such cases,
where appropriate the tests have been updated to check compiling for
soft float and a non-soft float variant (usually softfp). This was
usually because the target specified in the test defaulted to soft float.

This adds the frontend support required to support the use of the
comment pragma to enable auto linking on ELFish targets. This is a
generic ELF extension supported by LLVM. We need to change the handling
for the "dependentlib" in order to accommodate the previously discussed
encoding for the dependent library descriptor. Without the custom
handling of the PCK_Lib directive, the -l prefixed option would be
encoded into the resulting object (which is treated as a frontend
error).

Previously, RISCV32TargetInfo or RISCV64TargetInfo were created
unconditionally. Use LinuxTargetInfo<RISCV??TargetInfo> to ensure that the
proper OS-specific defines are present.
This patch only adds logic to instantiate LinuxTargetInfo and leaves a TODO,
as I'm reluctant to add logic for other targets (e.g. FreeBSD, RTEMS) until
I've produced and tested at least one binary for that OS+target combo.
Thanks to @mgrang to reporting the issue.

Summary:
#pragma STDC FP_CONTRACT handler is only registered in parser so we
should keep the unknown STDC pragma through preprocessor and we also
should not emit warning for unknown STDC pragma during preprocessor.

Summary:
xargs supports escaping of newline characters with backslash.
xargs -0 is neither part of POSIX nor the LSB.
This patch removes the -0 option and adjusts the input to xargs
accordingly; that is, the input is a text file not ending in an
incomplete line, and the newline of interest is preceded by a backslash.
Note: The treatment of escaped newline characters is not as clearly
specified by POSIX as for escaped blank characters; however, the same
can be said for escaped backslashes. It is slightly more clear for the
case where the -I option is used; however, -I is also of limited
portability.

I based that commit on what was in Intel's public documentation here https://software.intel.com/sites/default/files/managed/c5/15/architecture-instruction-set-extensions-programming-reference.pdf
Which specifically said CLWB wasn't until Icelake.
But I've since cross checked with SDE and it thinks these features exist on CNL and ICL. So now I don't know what to believe.
I've added test coverage of the current behavior as part of the revert so at least now have proof of what we're doing.

As reported in llvm bugzilla 32377.
Here’s a patch to add preinclude of stdc-predef.h.
The gcc documentation says “On GNU/Linux, <stdc-predef.h> is pre-included.” See https://gcc.gnu.org/gcc-4.8/porting_to.html;
The preinclude is inhibited with –ffreestanding.
Basically I fixed the failing test cases by adding –ffreestanding which inhibits this behavior.
I fixed all the failing tests, including some in extra/test, there's a separate patch for that which is linked here
Note: this is a recommit after a test failure took down the original (r318669)

This behaves similar to the __has_cpp_attribute builtin macro in that it allows users to detect whether an attribute is supported with the [[]] spelling syntax, which can be enabled in C with -fdouble-square-bracket-attributes.

Summary: This patch implements 4.3 of http://open-std.org/jtc1/sc22/wg21/docs/papers/2014/n4220.pdf. If a raw string contains a newline character, replace each newline character with the \n escape code. Without this patch, included test case (macro_raw_string.cpp) results compilation failure.

Fedora27 is using a new version of glibc that refers to the _Float128 type. This
patch adds that name as an alias to float128. I also added some predefined macro
values for the digits, mantissa, epilon, etc (FloatMacros). For the test case, I
copied an existing float128 test. This functionality needs work long term, but
it should be sufficient to tread water for a while. At Intel we have test
servers running our LLVM compiler with various open source workloads, the server
has been upgraded to Fedora27 so many workloads are failing due to _Float128.
