Guidance and Testing Architectures

[Philip Herron <herron.philip@xxxxxxxxxxxxxx>]

Hey

I have been playing around with GCC for some time now, tracing how it 
works etc. Looking for a regression to tackle, but a lot of regressions 
are architecture specific, i was wondering what is the best way to test 
GCC for cross-architecture problems.

As in do you use QEMU to run different architectures or is it best to 
run on a server. It would be great if i could get some guidance on where 
to start as in what regressions are still relevant as some are very old 
or are there any new projects to do something new in gcc to get involved 
in :). So far i have only built my own simple front-end some i 
understand some of how gcc works.
