Is there any intention to implement the DRNG instruction in FPC?

Pros:   fast, high entropy

Cons:  specific, possibly compromised by the NSA.

Using the Ivy Bridge DRNG would probably require "mixing" with other
DRNG's to remove biases created by the rumoured (supposed) NSA
tinkering where crypto is concerned. But where other uses are
concerned (simulation, gaming...) it would be much faster than current
methods.

DRNG may be used to improve the entropy of Free Pascal's random number
generator, if combined with other sources of randomness, but it
shouldn't be the only source of entropy. Additionally, any platform
dependence should be avoided, since DRNG is only implemented in
certain Intel architectures like the Ivy Bridge chipset.
