New Revision: 258814
URL: http://llvm.org/viewvc/llvm-project?rev=258814&view=rev
Log:
[Driver] Make sure -fno-math-builtin option is being passed by the driver.
Support for the -fno-math-builtin option was added in r186899. The codegen side
is being tested in test/CodeGen/nomathbuiltin.c. The missing part was just
passing the option through the driver.
