Refactoring: Introduce distinct host and target rpath var setters.
Two line summary: Distinguish HOST_RPATH and TARGET_RPATH; added RPATH_LINK_SEARCH; skip tests broken in stage1; general cleanup. `HOST_RPATH_VAR$(1)_T_$(2)_H_$(3)` and `TARGET_RPATH_VAR$(1)_T_$(2)_H_$(3)` both match the format of the old `RPATH_VAR$(1)_T_$(2)_H_$(3)` (which is still being set the same way that it was before, to one of either HOST/TARGET depending on what stage we are building). Namely, the format is <XXX>_RPATH_VAR = "<LD_LIB_PATH_ENVVAR>=<COLON_SEP_PATH_ENTRIES>" What this commit does: * Pass both of the (newly introduced) HOST and TARGET rpath setup vars to `maketest.py` * Update `maketest.py` to no longer update the LD_LIBRARY_PATH itself Instead, it passes along the HOST and TARGET rpath setup vars in environment variables `HOST_RPATH_ENV` and `TARGET_RPATH_ENV` * Also, pass the current stage number to maketest.py; it in turn passes it (via an env var) to run-make tests. This allows the run-make tests to selectively change behavior (e.g. turn themselves off) to deal with incompatibilities with e.g. stage1. * Cleanup: Distinguish in tools.mk between the command to run (`RUN`) and the file to generate to drive that command (`RUN_BINFILE`). The main thing this enables is that `RUN` can now setup the `TARGET_RPATH_ENV` without having to dirty up the runner code in each of the `run-make` Makefiles. * Cleanup: Factored out commands to delete dylib/rlib into REMOVE_DYLIBS/REMOVE_RLIBS. There were places where we were only calling `rm $(call DYLIB,foo)` even though we really needed to get rid of the whole glob (at least based on alex's findings on #13753 that removing the symlink does not suffice). Therefore rather than peppering the code with the awkward `rm $(TMPDIR)/$(call DYLIB_GLOB,foo)`, I instead introduced a common `REMOVE_DYLIBS` user function that expands into that when called. After I adding an analogous `REMOVE_RLIBS`, I changed all of the existing calls that rm dylibs or rlibs to use these routines instead. Note that the latter is not a true refactoring since I may have changed cases where it was our intent to only remove the sym-link. (But if that is the case, then we need to more deeply investigate alex's findings on #13753 where the system was still dynamically loading up the non-symlinked libraries that it finds on the load path.) * Added RPATH_LINK_SEARCH command and use it on Linux. On some platforms, namely Linux, when you have libboot.so that has its internal rpath set (to e.g. $(ORIGIN)/path/to/HOSTDIR), the linker still complains when you do the link step and it does not know where to find libraries that libboot.so depends upon that live in HOSTDIR (think e.g. librustuv.so). As far as I can tell, the GNU linker will consult the LD_LIBRARY_PATH as part of the linking process to find such libraries. But if you want to be more careful and not override LD_LIBRARY_PATH for the `gcc` invocation, then you need some other way to tell the linker where it can find the libraries that libboot.so needs. The solution to this on Linux is the `-Wl,-rpath-link` command line option. However, this command line option does not exist on Mac OS X, (which appears to be figuring out how to resolve the libboot.dylib dependency by some other means, perhaps by consulting the rpath setting within libboot.dylib). So, in order to abstract over this distinction, I added the RPATH_LINK_SEARCH macro to the run-make infrastructure and added calls to it where necessary to get Linux working. On architectures other than Linux, the macro expands to nothing. * Disable miscellaneous tests atop stage1. * An especially interesting instance of the previous bullet point: Excuse regex from doing rustdoc tests atop stage1. This was a (nearly-) final step to get `make check-stage1` working again. The use of a special-case check for regex here is ugly but is analogous other similar checks for regex such as the one that landed in PR #13844. The way this is written, the user will get a reminder that doc-crate-regex is being skipped whenever their rules attempt to do the crate documentation tests. This is deliberate: I want people running `make check-stage1` to be reminded about which cases are being skipped. (But if such echo noise is considered offensive, it can obviously be removed.) * Got windows working with the above changes. This portion of the commit is a cleanup revision of the (previously mentioned on try builds) re-architecting of how the LD_LIBRARY_PATH setup and extension is handled in order to accommodate Windows' (1.) use of `$PATH` for that purpose and (2.) use of spaces in `$PATH` entries (problematic for make and for interoperation with tools at the shell). * In addition, since the code has been rearchitected to pass the HOST_RPATH_DIR/TARGET_RPATH_DIR rather than a whole sh environment-variable setting command, there is no need to for the convert_path_spec calls in maketest.py, which in fact were put in place to placate Windows but were now causing the Windows builds to fail. Instead we just convert the paths to absolute paths just like all of the other path arguments. Also, note for makefile hackers: apparently you cannot quote operands to `ifeq` in Makefile (or at least, you need to be careful about adding them, e.g. to only one side). |

Add a new run-make test directory
This infrastructure is meant to support runnings tests that involve various interesting interdependencies about the types of crates being linked or possibly interacting with C libraries. The goal of these make tests is to not restrict them to a particular test runner, but allow each test to run its own tests. To this end, there is a new src/test/run-make directory which has sub-folders of tests. Each test requires a `Makefile`, and running the tests constitues simply running `make` inside the directory. The new target is `check-stageN-rmake`. These tests will have the destination directory (as TMPDIR) and the local rust compiler (as RUSTC) passed along to them. There is also some helpful cross-platform utilities included in src/test/run-make/tools.mk to aid with compiling C programs and running them. The impetus for adding this new test suite is to allow various interesting forms of testing rust linkage. All of the tests initially added are various flavors of compiling Rust and C with one another as well as just making sure that rust linkage works in general. Closes #10434 |
