| 550 .. function:: void gcc_jit_context_add_driver_option (gcc_jit_context *ctxt,\ | |
| 551 const char *optname) | |
| 552 | |
| 553 Add an arbitrary gcc driver option to the context, for use by | |
| 554 :func:`gcc_jit_context_compile` and | |
| 555 :func:`gcc_jit_context_compile_to_file`. | |
| 556 | |
| 557 The parameter ``optname`` must be non-NULL. The underlying buffer is | |
| 558 copied, so that it does not need to outlive the call. | |
| 559 | |
| 560 Extra options added by `gcc_jit_context_add_driver_option` are | |
| 561 applied *after* all other options potentially overriding them. | |
| 562 Options from parent contexts are inherited by child contexts; options | |
| 563 from the parent are applied *before* those from the child. | |
| 564 | |
| 565 For example: | |
| 566 | |
| 567 .. code-block:: c | |
| 568 | |
| 569 gcc_jit_context_add_driver_option (ctxt, "-lm"); | |
| 570 gcc_jit_context_add_driver_option (ctxt, "-fuse-linker-plugin"); | |
| 571 | |
| 572 Note that only some options are likely to be meaningful; there is no | |
| 573 "frontend" within libgccjit, so typically only those affecting | |
| 574 assembler and linker are likely to be useful. | |
| 575 | |
| 576 This entrypoint was added in :ref:`LIBGCCJIT_ABI_11`; you can test for | |
| 577 its presence using | |
