[llvm-commits] [llvm] r133713 - in /llvm/trunk: include/llvm/Support/FEnv.h lib/Analysis/ConstantFolding.cpp lib/Analysis/FEnv.h

[Dylan Noblesmith]

New Revision: 133713

URL: http://llvm.org/viewvc/llvm-project?rev=133713&view=rev
Log:
Support: make floating-exception header private

It has only one user. This eliminates the last include of
config.h from the public headers -- ideally, config.h
shouldn't even be installed by `make install` anymore.


Added:
    llvm/trunk/lib/Analysis/FEnv.h
      - copied, changed from r133709, llvm/trunk/include/llvm/Support/FEnv.h
Removed:
