New Revision: 142865

LTO isn't working in Morbo. Convert the -O4 to -O3 and ignore the -flto flag.

 Do not optimize.  This is the default.

 llvm-gcc is a C, C++, Objective-C and Objective-C++ compiler. llvm-g++ is a compiler driver for C++. llvm-gcc uses gcc front-end and gcc's command line interface. Consult the cc(1) man page for command line options supported by llvm-gcc. Only selected LLVM specific options are listed here.
 .Bl -tag -width -indent
-.It Fl flto
-Enables Link Time Optimization. Link Time Optimization is performed by ld(1) transparently using the LLVM optimizer. The object file generated contains intermediate LLVM bitcode instead of Mach-O objects.
-.It Fl O4
-Enables Link Time Optimization in addition to all optimizations enabled at -O3.
 .It Fl O
 Unlike gcc, -O means -O2 instead of -O1.
