[llvm-commits] [llvm] r125981 - /llvm/trunk/include/llvm/Support/StandardPasses.h

New Revision: 125981

URL: http://llvm.org/viewvc/llvm-project?rev=125981&view=rev
Log:
Now that -loop-idiom uses TargetLibraryInfo properly, it doesn't
need to be pulled out of the pass manager when the user specifies 
-fno-builtin.  It can intelligently determine which libcalls to
optimize based on what is enabled in TargetLibraryInfo.  This 
allows -fno-builtin-foo to work someday.
