do you know how i can set -xmangled from Instruments application?

 Here is an undocumented way.

 In the DATA section of a custom DTrace instrument, add:
#pragma D option mangled

Indeed DTrace understands glob patterns, not regular expressions.
man dtrace has examples of ObjC probes using such patterns.
The idiomatic way to match :: is to use ??.

I''ll also add that -xmangled was added to switch DTrace to use the
mangled representation instead of the default demangled one. It can
be very useful for C++ work.

This article might also be of interest:

Although it looks like the default there is to use mangled names.
