CodeSourcer's VxWorks toolchains support the following extension to __attribute__((constructor)):
void f __attribute__((constructor (N))); The number provided is a constructor priority. These are treated exactly like the arguments to the C++ init_priority attribute, which allows control over initialization priority order for namespace-scope C++ objects. The implementation is the same, too; all the C++ init_priority attribute does is create a magic function which is then given the appropriate priority. So, what this does is expose the functionality used for C++ for direct use from C. The attribute syntax above works in both C and C++, and is backwards-compatible; without the "(N)" you just get the default initialization priority, as you do at present. I plan to merge this functionality to the GCC mainline. Does anyone object to this feature, in principle? Thanks, -- Mark Mitchell CodeSourcery [EMAIL PROTECTED] (650) 331-3385 x713
