If you updated to the latest Rust snapshot before Feb. 13th, please perform a `./mach bootstrap-rust —force` to pull down a new version of the snapshot binaries.
Previously, we built our snapshots the same way that the Rust team does — Release build, but with LLVM assertions enabled. There was a large performance regression in one of those assertions, and we discovered that just disabling the assertions altogether resulted in a significant performance win. Since we haven’t seen an LLVM assertion in Servo’s compiles in over a year and a half (as far as we could recall), there didn’t seem to be any benefit to keeping them enabled, especially given the huge performance penalty. Enjoy your speedier Rust compiles! - Lars _______________________________________________ dev-servo mailing list dev-servo@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-servo
