1492291 - Wrap rustc invocations in the Tup backend to reflect build script outputs

Status: RESOLVED FIXED

(Firefox Build System :: General, enhancement)

Description

[Chris Manchester (limited bugmail, email directly)]

This covers a general solution to bug 1491169 as well as taking into account build script outputs such as cargo:rustc-cfg, cargo:include, cargo:rustc-env and friends.

The tentative plan is to capture the stdout of build script invocations in a file the tup backend knows about, and then pass that file to a wrapper that will parse it and execute the downstream rust compile with the appropriate flags and environment.
