//@ needs-target-std
//
// This is a simple smoke test for rustc's `--emit dep-info` feature. It prints out
// information about dependencies in a Makefile-compatible format, as a `.d` file.
// Note that this test does not check that the `.d` file is Makefile-compatible.
// This test first checks that emitting dep-info disables static analysis, preventing
// compilation of `erroneous.rs` from causing a compilation failure.
// Then, it checks that compilation using the flag is successful in general, even with
// empty source files or source files that contain a whitespace character.
// Finally, it removes one dependency and checks that compilation is still successful.
// See https://github.com/rust-lang/rust/pull/10698
use run_make_support::{rfs, rustc};
fn main() {
// We're only emitting dep info, so we shouldn't be running static analysis to
// figure out that this program is erroneous.
rustc().input("erroneous.rs").emit("dep-info").run();
rustc().input("lib.rs").emit("dep-info,link").crate_type("lib").run();
rfs::remove_file("foo.rs");
rfs::create_file("foo.rs");
// Compilation should succeed even if `foo.rs` is empty.
rustc().input("lib.rs").emit("dep-info,link").crate_type("lib").run();
// Again, with a space in the filename this time around.
rustc().input("lib_foofoo.rs").emit("dep-info,link").crate_type("lib").run();
rfs::remove_file("foo foo.rs");
rfs::create_file("foo foo.rs");
// Compilation should succeed even if `foo foo.rs` is empty.
rustc().input("lib_foofoo.rs").emit("dep-info,link").crate_type("lib").run();
// When a source file is deleted, compilation should still succeed if the library
// also loses this source file dependency.
rfs::remove_file("bar.rs");
rustc().input("lib2.rs").emit("dep-info,link").crate_type("lib").run();
