I haven't fully uncovered the secrets of
the compiler yet, but I did notice "pre-
peephole pass" under x86, but I think the
only functions it touched was one of the
bit shifts. Does this occur before
register allocation or was it just
something that had to be done before Pass
1?

Ideally yes, but this occurs after peephole optimisations where all of the register allocations have already been made.
Doing the peephole and deep optimisations while the registers are still in a virtual state would be better overall, but
may

Hi everyone,
Sorry to flood the mailing list again with more ideas and experiments.
I would like to propose introducing a new pair of in-built functions for the
compiler.

function CLog2(X: Cardinal):

I started to think about such names while
sleeping on it. Something like BitCount
would work splendidly for FLog2, and a
note in the documentation can be made to
show the similarity to the binary
logarithm. BinSearchSize is a little
restrictive, but I'm sure something
similar can be found.
