move `tools.mk` to run-make apparently I missed some tests in the last commit. Rather than having dozens of tests use the long version, use the short version in `run-make` and the long version in `run-make-fulldeps` (which is now only three tests) 2023-03-30 07:58:50 -05:00			`include ../tools.mk`
Include (potentially remapped) working dir in crate hash Fixes #85019 A `SourceFile` created during compilation may have a relative path (e.g. if rustc itself is invoked with a relative path). When we write out crate metadata, we convert all relative paths to absolute paths using the current working direction. However, the working directory is not included in the crate hash. This means that the crate metadata can change while the crate hash remains the same. Among other problems, this can cause a fingerprint mismatch ICE, since incremental compilation uses the crate metadata hash to determine if a foreign query is green. This commit moves the field holding the working directory from `Session` to `Options`, including it as part of the crate hash. 2021-08-12 15:30:40 -05:00
