Remove redundant `ignore-tidy-linelength` annotations This is step 2 towards fixing #77548. In the codegen and codegen-units test suites, the `//` comment markers were kept in order not to affect any source locations. This is because these tests cannot be automatically `--bless`ed. 2021-04-03 06:05:11 -05:00			`//`
rustc: Tweak filenames encoded into metadata This commit is a fix for #54408 where on nightly right now whenever generics are inlined the path name listed for the inlined function's debuginfo is a relative path to the cwd, which surely doesn't exist! Previously on beta/stable the debuginfo mentioned an absolute path which still didn't exist, but more predictably didn't exist. The change between stable/nightly is that nightly is now compiled with `--remap-path-prefix` to give a deterministic prefix to all rustc-generated paths in debuginfo. By using `--remap-path-prefix` the previous logic would recognize that the cwd was remapped, causing the original relative path name of the standard library to get emitted. If `--remap-path-prefix` wasn't passed in then the logic would create an absolute path name and then create a new source file entry. The fix in this commit is to apply the "recreate the source file entry with an absolute path" logic a bit more aggresively. If the source file's name was remapped then we don't touch it, but otherwise we always take the working dir (which may have been remapped) and then join it to the file to ensure that we process all relative file names as well. The end result is that the standard library should have an absolute path for all file names in debuginfo (using our `--remap-path-prefix` argument) as it does on stable after this patch.
