+// RUN: %clang_cc1 -compiler-options-dump -std=c++17 %s -o - | FileCheck %s --check-prefix=CXX17
+// RUN: %clang_cc1 -compiler-options-dump -std=c99 -ffast-math -x c %s -o - | FileCheck %s --check-prefix=C99
You don't need -ffast-math here I presume.

Comment at: test/Frontend/compiler-options-dump.cpp:15
+// CXX17: "extensions"
+// CXX17: "cxx_range_for" : true
cxx_range_for is both a feature and an extension?
