This is not that different from what gcc does for DWARF. Trouble is, there appear to exist optimization transformations which make such data difficult or impossible to generate. (In particular, it is unlikely to be easier to create specialized data like this if the compiler can't be made to create first-class DWARF for the same probe points / data values.) - FChE --S66JdqtemGhvbcZP Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.6 (GNU/Linux) iD8DBQFFDvYIVZbdDOm/ZT0RArc1AJ9GfTUPAgyp/bEeTbn4v9xl6K6bkQCcCor1 Ep2Wcgg7R0lKp/Hey04W/2o= =nJYr -----END PGP SIGNATURE----- --S66JdqtemGhvbcZP-- - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
