The structure was optimized out.

The compiler does attempt to do this in main() but not very successfully - it still manages to use unaligned offsets from %ebp in some cases. Also we need to have an aligned stack in case something uses SSE via _init(). MFC After: 1 week Keep the stack aligned to a 16 byte boundary when calling init functions 2005-05-19T07:31:06Z Doug Rabson dfr@FreeBSD.org 2005-05-19T07:31:06Z urn:sha1:0ff6455012ee33f2b3b64ad75fb765d2836347a9 so that we don't cause a bus error if they start storing SSE math stuff on the stack.

The previous commit inserted the call to _init_tls() between the call to atexit() and the restoration of the GP register clobbered by it. Fix: restore GP before we call _init_tls().
