By now I had run the test suite in x86_64-linux, without regressions.
Feel free to commit it then.

Hello,
I wonder whether it is possible to assign a priority (or order) of registers for FPC's register
allocator. Currently registers are allocated in the order of ordinals defined in cpubase.pas. On
i386 it doesn't make any difference, but on x86_64 'nonvolatile' rbx (and in Win64 also rsi

Hmm, that was the first thing I tried, but it doesnt't seem to make any
difference :(
No, it

I think the challenge is do design some generic infrastructure to tell
the register allocator about biasing it should do, and then to add some
heuristics somewhere else (like leaf/non-leaf) to give the register
allocator the proper instructions.

I understand the concern, but it should be handled somehow already. If we consider a non-leaf
function that
