-   <editor-description>
-    Here's GCC 3.1.x help (3.0.x's not given) :
- 
-    Instrument arcs during compilation to generate coverage data or for
-    profile-directed block ordering.  During execution the program
-    records how many times each branch is executed and how many times
-    it is taken.  When the compiled program exits it saves this data to
-    a file called sourcename.da for each source file.
- 
-    For profile-directed block ordering, compile the program with
-    -fprofile-arcs plus optimization and code generation options, generate
-    the arc profile information by running the program on a
-    selected workload, and then compile the program again with the same
-    optimization and code generation options plus -fbranch-probabilities.
- 
-    The other use of -fprofile-arcs is for use with "gcov", when it is
-    used with the -ftest-coverage option.  GCC supports two methods of
-    determining code coverage: the options that support "gcov", and
-    options -a and -ax, which write information to text files.  The
-    options that support "gcov" do not need to instrument every arc in
-    the program, so a program compiled with them runs faster than a
-    program compiled with -a, which adds instrumentation code to every
-    basic block in the program.  The tradeoff: since "gcov" does not
-    have execution counts for all branches, it must start with the execution
-    counts for the instrumented branches, and then iterate over
-    the program flow graph until the entire graph has been solved.
-    Hence, "gcov" runs a little more slowly than a program which uses
-    information from -a and -ax.
- 
-    With -fprofile-arcs, for each function of your program GCC creates
-    a program flow graph, then finds a spanning tree for the graph.
-    Only arcs that are not on the spanning tree have to be instrumented:
-    the compiler adds code to count the number of times that
-    these arcs are executed.  When an arc is the only exit or only
-    entrance to a block, the instrumentation code can be added to the
-    block; otherwise, a new basic block must be created to hold the
-    instrumentation code.
- 
-    This option makes it possible to estimate branch probabilities and
-    to calculate basic block execution counts.  In general, basic block
-    execution counts as provided by -a do not give enough information
-    to estimate all branch probabilities.

-   <editor-description>
-    After running a program compiled with -fprofile-arcs, you can compile it a
-    second time using -fbranch-probabilities, to improve
-    optimizations based on guessing the path a branch might take.
