Add `// run-pass` annotations to all the tests under `ui/run-pass/`. (I may have accidentally added it to some auxilliary crates as well; my emacs-macro-based methodology was pretty crude.) 2018-08-30 20:18:55 +08:00			`//@ run-pass`
trans: Link rlibs to dylibs with --whole-archive This commit starts passing the `--whole-archive` flag (`-force_load` on OSX) to the linker when linking rlibs into dylibs. The primary purpose of this commit is to ensure that the linker doesn't strip out objects from an archive when creating a dynamic library. Information on how this can go wrong can be found in issues #14344 and #25185. The unfortunate part about passing this flag to the linker is that we have to preprocess the rlib to remove the metadata and compressed bytecode found within. This means that creating a dylib will now take longer to link as we've got to copy around the input rlibs to a temporary location, modify them, and then invoke the linker. This isn't done for executables, however, so the "hello world" compile time is not affected. This fix was instigated because of the previous commit where rlibs may not contain multiple object files instead of one due to codegen units being greater than one. That change prevented the main distribution from being compiled with more than one codegen-unit and this commit fixes that.
