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`
Don't use `guess_head_span` in `predicates_of` for foreign span Previously, the result of `predicates_of` for a foreign trait would depend on the current state of the corresponding source file in the foreign crate. This could lead to ICEs during incremental compilation, since the on-disk contents of the upstream source file could potentially change without the upstream crate being recompiled. Additionally, this ensure that that the metadata we produce for a crate only depends on its compiled upstream dependencies (e.g an rlib or rmeta file), not the current on-disk state of the upstream crate source files. 2021-08-27 21:13:08 -05:00
