+@deffn {C Function} void gcc_jit_context_add_command_line_option (gcc_jit_context@w{ }*ctxt, const char@w{ }*optname)
+
+Add an arbitrary gcc command-line option to the context, for use
+by @pxref{15,,gcc_jit_context_compile()} and
+@pxref{4a,,gcc_jit_context_compile_to_file()}.
+
+The parameter @code{optname} must be non-NULL. The underlying buffer is
+copied, so that it does not need to outlive the call.
+
+Extra options added by @cite{gcc_jit_context_add_command_line_option} are
+applied @emph{after} the regular options above, potentially overriding them.
+Options from parent contexts are inherited by child contexts; options
+from the parent are applied @emph{before} those from the child.
+
+For example:
+
+@example
+gcc_jit_context_add_command_line_option (ctxt, "-ffast-math");
+gcc_jit_context_add_command_line_option (ctxt, "-fverbose-asm");
+@end example
+
+@noindent
+
+Note that only some options are likely to be meaningful; there is no
+"frontend" within libgccjit, so typically only those affecting
+optimization and code-generation are likely to be useful.
+
+This entrypoint was added in @pxref{6f,,LIBGCCJIT_ABI_1}; you can test for
+its presence using
+
+@example
+#ifdef LIBGCCJIT_HAVE_gcc_jit_context_add_command_line_option

+@section ABI and API compatibility
+
+
+The libgccjit developers strive for ABI and API backward-compatibility:
+programs built against libgccjit.so stand a good chance of running
+without recompilation against newer versions of libgccjit.so, and
+ought to recompile without modification against newer versions of
+libgccjit.h.
+
+@cartouche
+@quotation Note
+The libgccjit++.h C++ API is more experimental, and less
+locked-down at this time.
+@end quotation
+@end cartouche
+
+API compatibility is achieved by extending the API rather than changing
+it. For ABI compatiblity, we avoid bumping the SONAME, and instead use
+symbol versioning to tag each symbol, so that a binary linked against
+libgccjit.so is tagged according to the symbols that it uses.
+
+For example, @pxref{6e,,gcc_jit_context_add_command_line_option()} was added in
+@code{LIBGCCJIT_ABI_1}. If a client program uses it, this can be detected
+from metadata by using @code{objdump}:
+
+@example
+$ objdump -p testsuite/jit/test-extra-options.c.exe | tail -n 8

@subsection Tutorial part 2: Creating a trivial machine code function
@code{gccjit::context}, which is a thin C++ wrapper around the C API's
@pxref{8,,gcc_jit_context *}.
-Create one using @pxref{e3,,gccjit;;context;;acquire()}:
+Create one using @pxref{ec,,gccjit;;context;;acquire()}:
@example
gccjit::context ctxt;
expression is of a specific type, fixed at compile-time. In our example,
all of the expressions are of the C @cite{int} type, so let's obtain this from
the context, as a @code{gccjit::type}, using
-@pxref{e4,,gccjit;;context;;get_type()}:
+@pxref{ed,,gccjit;;context;;get_type()}:
@example
gccjit::type int_type = ctxt.get_type (GCC_JIT_TYPE_INT);
Memory management is easy: all such "contextual" objects are automatically
cleaned up for you when the context is released, using
-@pxref{e5,,gccjit;;context;;release()}:
+@pxref{ee,,gccjit;;context;;release()}:
@example
ctxt.release ();
One thing you can do with a @code{gccjit::object} is
to ask it for a human-readable description as a @code{std::string}, using
-@pxref{e6,,gccjit;;object;;get_debug_string()}:
+@pxref{ef,,gccjit;;object;;get_debug_string()}:
@example
printf ("obj: %s\n", obj.get_debug_string ().c_str ());
Let's create the function. To do so, we first need to construct
its single parameter, specifying its type and giving it a name,
-using @pxref{e7,,gccjit;;context;;new_param()}:
+using @pxref{f0,,gccjit;;context;;new_param()}:
@example
gccjit::param param_i = ctxt.new_param (int_type, "i");
Our basic block is relatively simple: it immediately terminates by
returning the value of an expression.
-We can build the expression using @pxref{e8,,gccjit;;context;;new_binary_op()}:
+We can build the expression using @pxref{f1,,gccjit;;context;;new_binary_op()}:
@example
gccjit::rvalue expr =
A @code{gccjit::rvalue} is another example of a
@code{gccjit::object} subclass. As before, we can print it with
-@pxref{e6,,gccjit;;object;;get_debug_string()}.
+@pxref{ef,,gccjit;;object;;get_debug_string()}.
@example
printf ("expr: %s\n", expr.get_debug_string ().c_str ());
@noindent
OK, we've populated the context. We can now compile it using
-@pxref{e9,,gccjit;;context;;compile()}:
+@pxref{f2,,gccjit;;context;;compile()}:
@example
gcc_jit_result *result;

@subsubsection Options
To get more information on what's going on, you can set debugging flags

By default, no optimizations are performed, the equivalent of GCC's
@cite{-O0} option. We can turn things up to e.g. @cite{-O3} by calling
-@pxref{ec,,gccjit;;context;;set_int_option()} with
+@pxref{f5,,gccjit;;context;;set_int_option()} with
