Do not run the specified passes to clean up and reduce the size of the test
Whenever the test program produces output on its standard output stream, it
should match the contents of F<filename> (the "reference output"). If you
do not use this option, B<bugpoint> will attempt to generate a reference output
-by compiling the program with the C backend and running it.

Profile file loaded by B<--profile-loader>.

+=item B<--run-{int,jit,llc,cbe,custom}>
Whenever the test program is compiled, B<bugpoint> should generate code for it
using the specified code generator. These options allow you to choose the
-interpreter, the JIT compiler, the static native code compiler, or the C
-backend, respectively.

+=item B<--safe-{llc,cbe,custom}>
+
+When debugging a code generator, B<bugpoint> should use the specified code
+generator as the "safe" code generator. This is a known-good code generator
+used to generate the "reference output" if it has not been provided, and to
+compile portions of the program that as they are excluded from the testcase.
+These options allow you to choose the
+static native code compiler, the C backend, or a custom command,
+(see B<--exec-command>) respectively. The interpreter and the JIT backends
+cannot currently be used as the "safe" backends.
+
+=item B<--exec-command> I<command>
+
+This option defines the command to use with the B<--run-custom> and
+B<--safe-custom> options to execute the bitcode testcase. This can
+be useful for cross-compilation.
+
+=item B<--safe-path> I<path>
+
+This option defines the path to the command to execute with the
+B<--safe-{int,jit,llc,cbe,custom}>
+option.
