20 Compiling a context
|
|
|
21 ===================
|
|
|
22
|
|
|
23 Once populated, a :class:`gccjit::context` can be compiled to
|
|
|
24 machine code, either in-memory via :func:`gccjit::context::compile` or
|
|
|
25 to disk via :func:`gccjit::context::compile_to_file`.
|
|
|
26
|
|
|
27 You can compile a context multiple times (using either form of
|
|
|
28 compilation), although any errors that occur on the context will
|
|
|
29 prevent any future compilation of that context.

31 In-memory compilation
|
|
|
32 *********************
|
|
|
33
|
|
|
34 .. function:: gcc_jit_result *\
|
|
|
35 gccjit::context::compile ()
|
|
|
36
|
|
|
37 This calls into GCC and builds the code, returning a
|
|
|
38 `gcc_jit_result *`.
|
|
|
39
|
|
|
40 This is a thin wrapper around the
|
|
|
41 :c:func:`gcc_jit_context_compile` API entrypoint.

|
|
43 Ahead-of-time compilation
|
|
|
44 *************************
|
|
|
45
|
|
|
46 Although libgccjit is primarily aimed at just-in-time compilation, it
|
|
|
47 can also be used for implementing more traditional ahead-of-time
|
|
|
48 compilers, via the :func:`gccjit::context::compile_to_file` method.
|
|
|
49
|
|
|
50 .. function:: void \
|
|
|
51 gccjit::context::compile_to_file (enum gcc_jit_output_kind,\
|
|
|
52 const char *output_path)
|
|
|
53
|
|
|
54 Compile the :class:`gccjit::context` to a file of the given
|
|
|
55 kind.
|
|
|
56
|
|
|
57 This is a thin wrapper around the
|
|
|
58 :c:func:`gcc_jit_context_compile_to_file` API entrypoint.
