// Since this is a short response file, clang must not use a response file
// to pass its parameters to other tools. This is only necessary for a large
// number of parameters.

// RUN: %clang -E @%t.0.txt %s -v 2>&1 | FileCheck %s -check-prefix=SHORT

// SHORT: extern int it_works;
// Check that clang is able to process long response files, routing a long
// sequence of arguments to other tools by using response files as well.
// We generate a 2MB response file to be big enough to surpass any system
// limit.
