From 57afa5a16ee24233f3e854ea42512b4442904f9f Mon Sep 17 00:00:00 2001 From: David Wood Date: Wed, 31 Jan 2024 11:44:09 +0000 Subject: [PATCH] compiletest: support auxiliaries with auxiliaries To test behaviour that depends on the extern options of intermediate crates, compiletest auxiliaries must have their own auxiliaries. Auxiliary compilation previously did not trigger compilation of any auxiliaries in the auxiliary's headers. In addition, those auxiliaries would need to be in an `auxiliary/auxiliary` directory, which is unnecessary and makes some crate graphs harder to write tests for, such as when A depends on B and C, and B depends on C. For a test `tests/ui/$path/root.rs`, with the following crate graph: ``` root |-- grandparent `-- parent `-- grandparent ``` then the intermediate outputs from compiletest will be: ``` build/$target/test/ui/$path/ |-- auxiliary | |-- libgrandparent.dylib | |-- libparent.dylib | |-- grandparent | | |-- grandparent.err | | `-- grandparent.out | `-- parent | |-- parent.err | `-- parent.out |-- libroot.rmeta |-- root.err `-- root.out ``` Signed-off-by: David Wood --- src/tools/compiletest/src/runtest.rs | 46 +++++++++---------- tests/ui/compiletest-self-test/aux-aux.rs | 8 ++++ .../auxiliary/aux_aux_bar.rs | 3 ++ .../auxiliary/aux_aux_foo.rs | 4 ++ 4 files changed, 38 insertions(+), 23 deletions(-) create mode 100644 tests/ui/compiletest-self-test/aux-aux.rs create mode 100644 tests/ui/compiletest-self-test/auxiliary/aux_aux_bar.rs create mode 100644 tests/ui/compiletest-self-test/auxiliary/aux_aux_foo.rs diff --git a/src/tools/compiletest/src/runtest.rs b/src/tools/compiletest/src/runtest.rs index f3a0e87d43a83..cfa45c73afda3 100644 --- a/src/tools/compiletest/src/runtest.rs +++ b/src/tools/compiletest/src/runtest.rs @@ -1936,7 +1936,7 @@ impl<'test> TestCx<'test> { fn document(&self, out_dir: &Path) -> ProcRes { if self.props.build_aux_docs { for rel_ab in &self.props.aux_builds { - let aux_testpaths = self.compute_aux_test_paths(rel_ab);
