+support enabled.
+
+@item -Wanalyzer-too-complex
+@opindex Wanalyzer-too-complex
+@opindex Wno-analyzer-too-complex
+If @option{-fanalyzer} is enabled, the analyzer uses various heuristics
+to attempt to explore the control flow and data flow in the program,
+but these can be defeated by sufficiently complicated code.
+
+By default, the analysis will silently stop if the code is too
+complicated for the analyzer to fully explore and it reaches an internal
+limit.
+
+The @option{-Wanalyzer-too-complex} option will warn if this occurs.
+
+@end table
+
+Pertinent parameters for controlling the exploration are:
+@option{--param analyzer-bb-explosion-factor=@var{value}},
+@option{--param analyzer-max-enodes-per-program-point=@var{value}},
+@option{--param analyzer-max-recursion-depth=@var{value}}, and
+@option{--param analyzer-min-snodes-for-call-summary=@var{value}}.
+
+The following options control the analyzer.
+
+@table @gcctabopt
+
+@item -fanalyzer-call-summaries
+@opindex fanalyzer-call-summaries
+@opindex fno-analyzer-call-summaries
+Simplify interprocedural analysis by computing the effect of certain calls,
+rather than exploring all paths through the function from callsite to each
+possible return.
+
+If enabled, call summaries are only used for functions with more than one
+call site, and that are sufficiently complicated (as per
+@option{--param analyzer-min-snodes-for-call-summary=@var{value}}).
+
+@item -fanalyzer-checker=@var{name}
+@opindex fanalyzer-checker
+Restrict the analyzer to run just the named checker.
+
+@item -fanalyzer-fine-grained
+@opindex fanalyzer-fine-grained
+@opindex fno-analyzer-fine-grained
+This option is intended for analyzer developers.
+
+Internally the analyzer builds an ``exploded graph'' that combines
+control flow graphs with data flow information.
+
+By default, an edge in this graph can contain the effects of a run
+of multiple statements within a basic block.  With
+@option{-fanalyzer-fine-grained}, each statement gets its own edge.
+
+@item -fno-analyzer-state-merge
+@opindex fanalyzer-state-merge
+@opindex fno-analyzer-state-merge
+This option is intended for analyzer developers.
+
+By default the analyzer will attempt to simplify analysis by merging
+sufficiently similar states at each program point as it builds its
+``exploded graph''.  With @option{-fno-analyzer-state-merge} this
+merging can be suppressed, for debugging state-handling issues.
+
+@item -fno-analyzer-state-purge
+@opindex fanalyzer-state-purge
+@opindex fno-analyzer-state-purge
+This option is intended for analyzer developers.
+
+By default the analyzer will attempt to simplify analysis by purging
+aspects of state at a program point that appear to no longer be relevant
+e.g. the values of locals that aren't accessed later in the function
+and which aren't relevant to leak analysis.
+
+With @option{-fno-analyzer-state-purge} this purging of state can
+be suppressed, for debugging state-handling issues.
+
+@item -fanalyzer-transitivity
+@opindex fanalyzer-transitivity
+@opindex fno-analyzer-transitivity
+This option enables transitivity of constraints within the analyzer.
+
+@item -fanalyzer-verbose-edges
+This option is intended for analyzer developers.  It enables more
+verbose, lower-level detail in the descriptions of control flow
+within diagnostic paths.
+
+@item -fanalyzer-verbose-state-changes
+This option is intended for analyzer developers.  It enables more
+verbose, lower-level detail in the descriptions of events relating
+to state machines within diagnostic paths.
+
+@item -fanalyzer-verbosity=@var{level}
+This option controls the complexity of the control flow paths that are
+emitted for analyzer diagnostics.
+
+The @var{level} can be one of:
+
+@table @samp
+@item 0
+At this level, interprocedural call and return events are displayed,
+along with the most pertinent state-change events relating to
+a diagnostic.  For example, for a double-@code{free} diagnostic,
+both calls to @code{free} will be shown.
+
+@item 1
+As per the previous level, but also show events for the entry
+to each function.
+
+@item 2
+As per the previous level, but also show  events relating to
+control flow (e.g. ``true path taken'' at a conditional).
+
+This level is the default.
+
+@item 3
+This level is intended for analyzer developers; it adds various
+other events intended for debugging the analyzer.
