Hello Tim,
can you specify which versions, maybe post the commandline, or trying to
compile for 32bit (-m32 switch)?
Also I dont understand the comment about splitting - to avoid
misunderstanding - the generated code segfaults on my AthlonX2 so its not
a question about optimal code, but actually working one
Im unable to generate the right instruction, and I dont exactly know why
it should differ between versions (... except bugs of course...).
And I just want to know the right way to force unaligned loads, without
inline assembly.
Btw: The code doesnt compile on gcc < 4.7 as I just realised - cant
multipy vector with scalars on older versions.
