Finally, it is up to Intel and AMD to come up with hardware memory tagging, so far they have messed up all attempts, with MPX being the last short lived one.
It's good info, and I wouldn't rush a migration off of SPARC systems if I was already using them, but slow death is still death. It was already worrying that workstations were killed off by Sun before the Oracle acquisition; it seems quite clear that no one has been serious about spreading adoption of the architecture for more than two decades now.
Kind of. Atos still sell GCOS/GECOS mainframes, but they are Xeon boxes running emulators. Same with Unisys and MCP (which was written in an ALGOL and had bounds checked IIRC).
