+/* In this file value profile based optimizations are placed. Currently the
+ following optimizations are implemented (for more detailed descriptions
+ see comments at value_profile_transformations):
+
+ 1) Division/modulo specialization. Provided that we can determine that the
+ operands of the division have some special properties, we may use it to
+ produce more effective code.
+
+ 2) Indirect/virtual call specialization. If we can determine most
+ common function callee in indirect/virtual call. We can use this
+ information to improve code effectiveness (especially info for
+ the inliner).
+
+ 3) Speculative prefetching. If we are able to determine that the difference
+ between addresses accessed by a memory reference is usually constant, we
+ may add the prefetch instructions.
+ FIXME: This transformation was removed together with RTL based value
+ profiling.
+
+
+ Value profiling internals
+ ==========================
+
+ Every value profiling transformation starts with defining what values
+ to profile. There are different histogram types (see HIST_TYPE_* in
+ value-prof.h) and each transformation can request one or more histogram
+ types per GIMPLE statement. The function gimple_find_values_to_profile()
+ collects the values to profile in a vec, and adds the number of counters
+ required for the different histogram types.
+
+ For a -fprofile-generate run, the statements for which values should be
+ recorded, are instrumented in instrument_values(). The instrumentation
+ is done by helper functions that can be found in tree-profile.c, where
+ new types of histograms can be added if necessary.
+
+ After a -fprofile-use, the value profiling data is read back in by
+ compute_value_histograms() that translates the collected data to
+ histograms and attaches them to the profiled statements via
+ gimple_add_histogram_value(). Histograms are stored in a hash table
+ that is attached to every intrumented function, see VALUE_HISTOGRAMS
+ in function.h.
+
+ The value-profile transformations driver is the function
+ gimple_value_profile_transformations(). It traverses all statements in
+ the to-be-transformed function, and looks for statements with one or
+ more histograms attached to it. If a statement has histograms, the
+ transformation functions are called on the statement.
+
+ Limitations / FIXME / TODO:
+ * Only one histogram of each type can be associated with a statement.
+ * Some value profile transformations are done in builtins.c (?!)
+ * Updating of histograms needs some TLC.
+ * The value profiling code could be used to record analysis results
+ from non-profiling (e.g. VRP).
+ * Adding new profilers should be simplified, starting with a cleanup
+ of what-happens-where and with making gimple_find_values_to_profile
+ and gimple_value_profile_transformations table-driven, perhaps...
