Create binaries that can later be used by the optimization and observability tools binopt(1), code-analyzer(1), discover(1), collect(1), and uncover(1).
The default on Oracle Solaris is -xannotate=yes. The default on Linux is -xannotate=no. Specifying -xannotate without a value is equivalent to -xannotate=yes.
For optimal use of the optimization and observability tools, -xannotate=yes must be in effect at both compile and link time. Compile and link with -xannotate=no to produce slightly smaller binaries and libraries when optimization and observability tools will not be used.
