I do not believe that there exists any reason for naming the non-orthogonal use of registers as "practical".


There is one and only one advantage of the non-orthogonal use of registers, albeit an important advantage: a shorter encoding for the corresponding instructions.

When Intel 8086 has been designed, having an instruction encoding as short as possible was considered the top priority, and the result was that in 8086 there were no identical registers. Even among the 8 supposedly general-purpose registers, each register had different properties from every other register.

When AMD has designed the x86-64 ISA, they had the opportunity of adding 8 identical general-purpose registers, but for reasons completely beyond my power of comprehension, they have screwed that very badly.

Instead of adding 1 extra kind of general-purpose registers, they have added 3 distinct kinds, R12, R13 and the other 6 new registers. They appear to have saved thus literally a few transistors in an Opteron core with many millions of transistors, by replacing a few AND gates with 4 inputs with AND gates with 3 inputs, and thus making an incomplete decode of the register fields in some of the addressing modes.


A moderate amount of non-orthogonality in register use is desirable, both for a more compact encoding and for the partitioning of the registers into subsets that can operate concurrently without the need of having more ports for each registers.

So it is useful to have maybe 4 or 5 kinds of registers, e.g. GPRs, wide registers a.k.a. vector registers, mask registers, maybe flags registers, maybe even a few special registers for the support of certain instructions, like long multiplication/division/shift.


On the other hand, extreme non-orthogonality of the register usage, like in x86-64, where there are maybe 20 or more different kinds of registers accessible in non-privileged programs (even the SSE/AVX registers are not all identical as the length of the instruction encoding differs depending on the register choice), is very bad in my opinion and it is by far the main feature that I have always hated in the Intel CPUs.

If one declares a large number of instructions of x86-64 as obsolete and no longer to be used in new programs, the number of distinct register types in x86-64 diminishes considerably, but there still remain far too many register types.


The consequence of this is that unlike for other ISAs, for x86-64 it is very difficult to make an optimal register allocation. Choosing a certain register that seems the best at some point may require either extra register movements or a longer encoding for some instructions at a much later time.

The compilers do not always allocate the registers optimally even in the simple case when there are just a few kinds of registers with many equivalent registers of each kind. For x86-64, a non-optimal register allocation is frequent.

When writing in assembly, an optimal allocation may be possible, but it may require a lot of time spent for it in order to examine long-range interactions between instructions, which is seldom worthwhile.


It is true that the non-optimal allocation of the registers in x86-64 has seldom more severe consequences than some additional 1 or 2 extra bytes per instruction encoding here and there, which may have only minor effects on the program size and speed in comparison with other more important factors, like data structures, algorithms or concurrency.

Nevertheless, at least for me, when the number of different kinds of registers is too large, this intellectual difficulty in ensuring that a program is the best that can be written is annoying and ugly.
