[PATCH] D40673: Add _Float128 as alias to __float128 to enable compilations on Fedora27/glibc2-26

mibintc created this revision.
mibintc added a project: clang.

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. What do you think?
