2017-12-29Revert r321504 "[X86] Don't accidentally enable PKU on cannon lake and ↵Craig Topper
icelake or CLWB on cannonlake." 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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@321547 91177308-0d34-0410-b5e6-96231b3b80d8

2017-12-04Add _Float128 as alias to __float128 to enable compilations on ↵Erich Keane
Fedora27/glibc2-26 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.

2017-11-30[ARM] disable FPU features when using soft floating point.Keith Walker
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.

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 Patch By: mibintc Differential Revision: https://reviews.llvm.org/D34158 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@318669 91177308-0d34-0410-b5e6-96231b3b80d8

2017-11-17[MinGW] Define __ARM_DWARF_EH__ for MinGW/ARMMartin Storsjo
Since SVN r318510, the MinGW/ARM configuration defaults to dwarf exception handling. Differential Revision: https://reviews.llvm.org/D39533 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@318511 91177308-0d34-0410-b5e6-96231b3b80d8

2017-10-28Basic: improve coverage for Darwin targets and fix ABISaleem Abdulrasool
The existing coverage for the Darwin targets wasn't enough to catch all the variations. Improve the coverage a bit further and fix a few cases for Darwin targets. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@316826 91177308-0d34-0410-b5e6-96231b3b80d8
2017-10-27ARM: centralise SizeType, PtrDiffType, and IntPtrTypeSaleem Abdulrasool
Centralise the definitions of these compiler vended types to aid inspection to ensure that they are defined similarly. The one case that stands out is the Darwin case where the types do not match up. This fixes the API conformance for APCS-GNU as well. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@316810 91177308-0d34-0410-b5e6-96231b3b80d8
2017-10-26[X86] Make -march=i686 an alias of -march=pentiumproCraig Topper
I think the only reason they are different is because we don't set tune_i686 for -march=i686 to match GCC. But GCC 4.9.0 seems to have changed this behavior and they do set it now. So I think they can aliases now. Differential Revision: https://reviews.llvm.org/D39349 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@316712 91177308-0d34-0410-b5e6-96231b3b80d8

2017-10-20Basic: restore {,u}intptr_t on NetBSD/ARMSaleem Abdulrasool
NetBSD uses `long int` for `intptr_t` on ARM. This was changed in SVN r316046, referenced against other compilers. However, NetBSD's reference was incorrect as the current clang behaviour is more up-to-date. Restore the original behaviour for that target. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@316204 91177308-0d34-0410-b5e6-96231b3b80d8

2017-10-19Try to shorten system header paths when using -MD depfilesPeter Wu
GCC tries to shorten system headers in depfiles using its real path (resolving components like ".." and following symlinks). Mimic this feature to ensure that the Ninja build tool detects the correct dependencies when a symlink changes directory levels, see https://github.com/ninja-build/ninja/issues/1330 An option to disable this feature is added in case "these changed header paths may conflict with some compilation environments", see https://gcc.gnu.org/ml/gcc-patches/2012-09/msg00287.html Note that the original feature request for GCC (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=52974) also included paths preprocessed output (-E) and diagnostics. That is not implemented now since I am not sure if it breaks something else.
