We currently build our x86 build with -march=i486. There was some old
soekris and alix(?) board that had cpu with 486 instruction set.
There are issues with mesa:
[ 12956.121] (EE) AIGLX error: dlopen
of /usr/lib/xorg/modules/dri/i915_dri.so failed (Error
__sync_val_compare_and_swap_8: symbol not found)
This is because 64bit atomic ops are not available for i486.
mono and some other package (sems?) had similar issue. There are
I think we want drop i486 support and move to -march=i586 or newer and
I think we want do that sooner than later.
The question is: What 32 bit architecture should we aim for? i586?
i686? Do we need/want support non PAE hardware?
What are the lowest boards people are using nowdays?
