@@ -1335,7 +1335,6 @@ To debug issues with the generated C code, you can pass these flags:
 
 - `-cg` - produces a less optimized executable with more debug information in it.
 - `-keep_c` - keep the generated C file, so your debugger can also use it.
-- `-pretty_c` - run clang-format over the generated C file, so it looks nicer and is easier to read.
 - `-show_c_cmd` - prints the C command that is used to build the program.
 
 For best debugging experience, you can pass all of them at the same time: `v -cg -keep_c -pretty_c -show_c_cmd yourprogram.v` , then just run your debugger (gdb/lldb) or IDE with the produced executable `yourprogram`.
