Which critical features? > For example Stable inline asm support which got merged in 1.95. It is not needed that the support is stable, but rather that everything you may need works. >From a quick test (with a dummy example that may not be representative), ppc64 inline assembly seems to work for a long time, way before Rust 1.95. So, which is the actual version that it is needed? i.e. 1.95.0 doesn't seem to be required at least due to that. That is why I am asking about the critical features above, because it may be that this works since earlier versions. (I wonder if this patch and s390's similar one influenced each other?) Thanks!
