This is not true.
The VRSAVE functionality is a compiler switch. The reason behind this
is that some developers need to control the VRSAVE register directly
and don't want the compiler to generate this code. There are also
cases where you are calling nested functions that don't require using
VRSAVE as an optimization in tight loops, etc.
Alex,
Can you be more explicit? I am not familiar with a compiler
switch to turn vrsave off. By default the compiler should and does
generate vrsave code (except when misbehaving).
