Description

See the  Original RT.

Currently PASM registers are limited to 2 digits. That is, P99 is a valid register, but P999 is not.

PIR maps the large numbers to "physical" parrot registers; I claim in the original RT that this same mapping should apply to PASM registers, but: I cannot find the reference to support this, and parrot -t1 output shows that P99 uses register # 99.

So, this needs an architectural decision; Should PASM do a similar arbitrary mapping of register numbers? If so, code needs fixing.

If not, the test in t/compilers/syn/regressions.t for PASM needs to be removed, the docs need to be updated to indicate there is a hard limit for PASM registers, (and we might want to decide if we want that hard limit increased, as it's currently 100)
