- Subject: disable avx instructions at runtime
hi all,
i'm using a debugger, that does not support avx instructions (at least
the back-in-time functionality doesn't). unfortunately, glibc/libm uses
some sort of runtime dispatching to provide an avx-implementation for
mathematical functions like sin or cos.
therefore i wonder, is there a way to disable the run-time dispatching
and for the use of the non-avx implementations in glibc?
thanks,
tim
