"Spectre" is one of two notorious bugs of modern CPUs involving speculative
execution. I rather doubt that VAX is affected by this but I suspect others here have a
lot more knowledge.

So, this is a bug report:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=86811
GCC would like to know if VAX needs Spectre-related work.
Are any of the VAXes ever made capable of speculative execution? the
first tech for doing it was in 1967, so not entirely far-fetched.
