(In reply to comment #18) > Just tried oibaf's radeonsi_dri.so to copy here on Debian (just to be sure > :D) and it suffers from the same problem with -march=generic ;)
I mean -mtune=generic of course :).
Now to bisect where that SSE4.1 code start to compile this slow (4 minututes on Kabini just for that) :D Issue also not present on 64bit ;)
I haven't seen the perf issue on my pure 64 bit setup, but have noticed that the compile sits on sse4.1 for a while recently - just using one core, like it's blocking the other threads of a make -j5 till it's done.
Oh i bisected that ine, it takes 200X more time to compile on 32bit :D , actually compile libmesa_gallium i think this is the commit:

Greetings and happy 'bisecting'...;-)

So what is the solution for that after one month? Simply to use -O0 maybe :)
Ping Jason Ekstrand, maybe 8-)
Ping.
