Load from memory, ALU operation to set flags, jump on flags that were just set.

FWIW, in some CPUs, the load instructions will also set/clear the "zero" and "negative" flags.

You are right. As a rule, today's optimizing compilers are very good at producing (near) best machine code.

With Perl, I'd say just write the most understandable and maintainable code you can.
