Well, MIPS and ARM are well supported by simulators, which is how a lot of
people test patches that are going to affect the core compiler and potentially
have side effects on many platforms, e.g. when merging a big branch with some
major new functionality to trunk. But very many patches are either clearly
target-specific, or clearly generic enough or simple enough that it's seen as
fair to apply them after testing on common/popular platforms and fix any
side-effects that show up on peculiar or uncommon hosts as they manifest.
HEAD is implicitly unstable (except during the stage 3 stabilisation process
before a release of course.)
