ARM has fingers

The IT (If-Then) instruction makes up to four following instructions (the IT block) conditional. The conditions can be all the same, or some of them can be the logical inverse of the others.
LOL. I don't think even the VAX had one of those.

ARM assembly guru here. They removed conditional execution from the newer AArch64 (aka ARM64) architecture. It was becoming more of a nuisance with the introduction of deeper pipelines, instruction parallelism, and instruction reordering--it can be done, but it requires a combinatorial explosion of gates the deeper the pipeline gets.

With ARM being on the small form-factor, low-power consumption part of the spectrum, it made sense to drop it.
