crosstool vs. crosstool-ng

[Harold Grovesteen-2]

I am new to this group, so I am likely asking something that is already
understood.  So, apologies for bringing up possibly old topics.  
Recently I used crosstool to build a toolchain for s390 target on
Intel.  Following that, I found this list list and started to see
messages about crosstool-ng.  Downloaded it.  crosstool-ng I realize
does not support s390.  But, crosstool seems to have stopped being
enhanced at a few versions of the tools back.  To develop toolchains
with more recent versions or gcc or binutils should I look at adding
code to crosstool, or work on adding s390 support to crosstool-ng?

I guess I am really trying to understand the relationship between the
two projects.

Thanks,
Harold Grovesteen

Basically, crostool is unmaintained since several years (3-4 years ?).
Crosstool-ng is its successor, and development is only taking place on
crosstool-ng.

I'm quite sure Yann (crosstool-ng's maintainer) will be interested by
patches adding support for S390 to crosstool-ng.

Sincerly,

Thomas

As Thomas pointed out, I would be glad if someone ( you? :-) ) would
submit patches to support another architecture! That should be quite
easy, basically adding a file in config/arch/s390.in and another one
in scripts/build/arch/s390.sh .

Basically, crosstool-NG started as a fork of (the original) crosstool;
over time it grew many enhacements. Unfortunately, lacking the appropriate
hardware (and time!) I can not test every architectures, so some archs
supported by crosstool have not yet been added/ported to crosstool-NG.
