The advanced loads (sort of software controlled speculative loads) were real goofy too (but neat!)
x86 sort of has two stacks today as a security mitigation https://techcommunity.microsoft.com/t5/windows-kernel-intern...
Being VLIW was probably the least weird part of Itanium. The NaT ("not a thing") bit on every register was the weirdest part and probably the one which tripped people the most. And like SPARC, it had register windows. It also had a pair of stacks instead of a single one, a set of predicate registers (which also had their own register windows), and plenty of other assorted weirdness.
