(1) Well... I guess that emulating the linux userspace APIs is one of
the necessary things to acquire, to be able to run Firefox, Adobe Flash,
linux user programs... It is somewhat easier than emulating the entire
linux (with hardware drivers)...
(2) Non-emulating approach could be (A) to rewrite Linux in Smalltalk or
(B) to semi-automatically metaprogrammatically convert Linux into
Smalltalk. I think this approach (2) is more feasible than emulating
approach (1) and will think more on (2).
(2.1) It would help to write a semi-automatic metaprogrammatic converter
environment for (2B). To do (2.1), a gcc + g++ backend generating a
{Smalltalk+asm} code seems to be necessary. So gcc + g++ should be
modified for this. This is highly complex task as gcc is highly complex,
but (I think is) much more feasible than the emulator (1).
***
Meanwhile, I will try to study gcc's source code. This might require
years of study of gcc's sources.
WBR,
