Actually, the lineage of how the MIPS ucode/pixie compiler got to DEC
was not because "some of them [MIPS compiler people] later moved from
MIPS to DEC," but rather because DEC had developed a series of
machines based on the MIPS R3000 chip, long before SGI bought MIPS,
and DEC had licensed the MIPS compiler system source code from MIPS.


DEC later used that C compiler source code to get their Alpha machine
up and running. Since then, I understand, DEC has been working on
their own C compiler system.
