i686 require SSE4.1-capable processor?
Hi
I'm maintaining a package (filezilla) which just got a bug report that
it simply crashes on program start - It gets a SIGILL - "Illegal
instruction". (#1076312 report [1]).
After the reporter debugged it, it seems like it crashes on the
assembler instruction "pinsrd", which looks like it was added in
SSE4.1, while the reporter runs this on a
Intel(R) Celeron(R) M CPU 420 @ 1.60GHz
which only supports SSE2. (Full cpuinfo available in the report) - So, my
question is - is this a cpu that is too old for Debian to support, or
should we support it, and Debian gcc generates invalid code requiring SSE4.1
while it still should support SSE2? (Or is the problem something else
completely?)
