John Ericson	39753f5360	top-level: Close over fewer arguments for stdenv stages ... This makes the flow of data easier to understand. There's little downside because the args in question are already inspected by the stdenvs. cross-compiling in particular is simpler because we don't need to worry about overriding the config closed over by `allPackages`.	2016-11-30 19:11:03 -05:00
John Ericson	d240a0da1a	top-level: Remove cycles: stdenv calls in top-level but not vice versa ... This commit changes the dependencies of stdenv, and clean-up the stdenv story by removing the `defaultStdenv` attribute as well as the `bootStdenv` parameter. Before, the final bootstrapping stage's stdenv was provided by all-packages, which was iterating multiple times over the top-level/default.nix expression, and non-final bootstrapping stages' stdenvs were explicitly specified with the `bootStdenv` parameter. Now, all stages' stdenvs are specified with the `stdenv` parameter. For non-final bootstrapping stages, this is a small change---basically just rename the parameter. For the final stage, top-level/default.nix takes the chosen stdenv and makes the final stage with it. `allPackages` is used to make all bootstrapping stages, final and non-final alike. It's basically the expression of `stage.nix` (along with a few partially-applied default arguments) Note, the make-bootstrap-tools scripts are temporarily broken	2016-11-30 19:10:59 -05:00

John Ericson	f68e16f023	top-level: Make cross compiling slightly saner ... Removes the weird stdenv cycle used to match the old infrastructure. It turns out that matching it so precisely is not needed.	2016-11-12 20:20:44 +01:00
