[erlang-questions] Elbrus 2K support

[Max Lapshin]

Hi.

We have successfully compiled erlang 19.0 under Elbrus 2K.  It is russian
computer with VLIW architecture and transparent support for amd64
instructions execution.

$ uname -a

Linux EL2S4-53-31 3.14.46-elbrus.314.1.14 #1 SMP Mon Sep 21 22:13:08 GMT
2015 e2k E2S EL2S4 GNU/Linux


Right now we have tested how it works in amd64 emulation and had to make
some trivial hacks for it to compile (patch in the end of email), because
compiler is lcc:

$ lcc -v

lcc:1.20.09:Aug-27-2015:e2k-4c-linux

Thread model: posix

gcc version 4.4.0 compatible.

Stackoverflow couldn't help us with compiling under elbrus, so I decided to
make two dirty patches =)


Erlang and thus our Flussonic can run on this architecture. Thank you for
portable code!
