	Currently the behavior is as follows (where stageN <-> stage(N-1) artifacts, except for stage0 libstd):

	- `x.py build --stage 0`:
	- stage0 libstd
	- stage0 rustc (but without putting rustc in stage1/)

	This leaves you without any rustc at all except for the beta compiler
	(https://github.com/rust-lang/rust/issues/73519). This is never what you want (currently you should use either `x.py check` or `x.py build --stage 0 src/libstd` instead).

	- `x.py build --stage 1`:

docs.rs benchmarks

	# summary

	docs.rs is _much_ faster than my hard disk.
	Adding concurrency reduces overall time but increases individual time
	Most of the delay on current prod is due to network latency, not CPU time
	I cannot reproduce the CPU usage locally - requests are just as fast or faster on the version that overloaded prod as on the latest version.

	## extended timing info

	### Current prod (I _believe_ c3d3ed3d2e0c4274c0c12a7b1f5e56e68eb8b8bf, remote)

jyn514 / fib.s

Created October 22, 2019 21:32

Fibonacci in MIPS assembly without a jump instruction

	# fibonacci sequence in MIPS
	# $s0 stores the next to last item in the sequence
	# $s1 stores the last item in the sequence

	# this is just for initialization
	li $t0, 1 # F_1 (since F_0 is 0, we don't need to initialize the registers)

	seq $t1, $s1, $0 # if s1 == 0 this is the first run

	# conditional move: if (t1) s1 = t0
