Force setjmp/longjmp for long control transfers.
|
|
|
|
The default long control transfer provider is setjmp/longjmp because it
|
|
is the most portable option. When a better provider is known for a platform,
|
|
Duktape may default to that (e.g. _setjmp/_longjmp is the default for
|
|
OSX/iPhone, see GH-55). With this feature option you can force Duktape to
|
|
explicitly use setjmp/longjmp even in these cases.
|
|
|
|
The downside of setjmp/longjmp is that signal mask saving behavior is not
|
|
specified and varies between platforms. Signal mask saving may have a
|
|
significant performance impact so you may want to force a specific provider
|
|
if performance matters for your application.
