I tried to run Tumbleweed on i586 today and when starting Gnome on X11

It's the usual crap that programs make use of sse2
without checking cpuid AT DAMN RUNTIME.

webkit2gtk3 build log:

Glad to see that the processor is not yet entirely unsupported. Shall I
open a bug report for this problem?

That will be tough: webkit2gtk claims in the CMake files:

message(FATAL_ERROR "SSE2 support is required to compile WebKit")
endif ()

Wonderful! It forces its requirements on every piece of the software
stack that depends on it. However, I wonder what they do on arm.

I don't strictly depend on Gnome. I use the machine for kernel
development and Gnome/X11 is just one of my smoke tests. Twm works
nicely BTW! :)
