What is the fastest way to rebuild stage 1 compiler when working on
librustc/hir? Currently adding a single
debug! line takes 12m with
./x.py build --stage 1 -j 8.
--stage 1 rebuilds libraries too, which makes sense, but my changes won't be changing generated code so if possible I'd like to avoid that and only build the compiler. Is this possible?
you can likely get away with
x.py build --stage 1 src/libtest
Just tired that, but it still rebuilds
