\| \| \| \| \| \|	Quartus assumes unsigned multiplication by default, breaking signed multiplies, so add an input signedness parameter to the MISTRAL_MUL* cells to propagate to Quartus' <family>_mac cells.

*	intel_alm: direct LUTRAM cell instantiation	Dan Ravensloft	2020-05-07	1	-0/+39
\| \| \| \| \| \| \| \| \| \|	By instantiating the LUTRAM cell directly, we avoid a trip through altsyncram, which speeds up Quartus synthesis time. This also gives a little more flexibility, as Yosys can build RAMs out of individual 32x1 LUTRAM cells. While working on this, I discovered that the mem_init0 parameter of <family>_mlab_cell gets ignored by Quartus.

*	synth_intel_alm: alternative synthesis for Intel FPGAs	Dan Ravensloft	2020-04-15	1	-0/+23
	By operating at a layer of abstraction over the rather clumsy Intel primitives, we can avoid special hacks like `dffinit -highlow` in favour of simple techmapping. This also makes the primitives much easier to manipulate, and more descriptive (no more cyclonev_lcell_comb to mean anything from a LUT2 to a LUT6).
