Unfortunately, I have tripped across something that
is quite bad. Compiling on Linux x86 targeting the
PowerPC or SPARC leads to a huge compilation time
on a single file.
FWIW. I see the same behavior for i386-unknown-netbsdelf3.1 too (when compiling natively, i.e. not using cross compiler).

Is there a PR for this or do I need to file one?

The problem was introduced by revision 125624 (the dataflow merge).

Thank you for confirming it wasn't just me or my configuration. This looks like a serious issue to me.
