Do I have to define a new BSP?
Did anyone have a similar problem and could give me some advice?
IIRC, genericx86 targets Atom and higher (the README lists the target
hardware) so it's quite possible that the compiler is emitting
instructions that your CPU doesn't actually have. You could create a
new BSP, or edit the tune flags from your distro or local
configuration to target your CPU.
I believe that this AMD Sempron processor is using an older instruction set. So
as Ross indicated, the best approach is to define a correct tune and BSP for
your part.
Looking at what I found online, it appears the Sempron 2100 supports:
MMX, 3DNow!, SSE, SSE2, SSE3, AMD64 and EVP
The atom tune is compatible with the core2 tune. The core2 supports
MMX, SSE, SSE2, SSE3, SSE4.1, and Supplemental SSE3
So my guess is that last two items is the issue. If you copy the genericx86 BSP
and modify the configuration to use the tune-x86_64.inc instead, that may fix
your issue.
