What's hard is getting the costing models properly updated after the range split without rescanning the entire function. My range splitting code works on BBs/EBBs boundaries, but it wouldn't be that hard to add splitting within a BB. jeff -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org/ iQEcBAEBAgAGBQJOMXZNAAoJEBRtltQi2kC7HIMH/AtqJol9OpquhnN1VFCI5tyY BC7GeqMeKU0a1Xz/qUONnK9CZghyVM4S6wqRsC5ZsmGjlDN6zjkGTNFNbM6hFxI3 iTkTz0Etf/M+tjmE89Kbyp0tq68UZuZ69UPDBX+cIZJKuzsvnnzjGDYgeUTns5Fw +UqOzQ5PriPqsCJfdG+jjtbgyIIe6X/NChlVn3TjfT/XYuZwsgGK5IDUB7/bX0t2 YCvf/NggXJVcH7419ShiBMTD4zGe9gqYpLfn8yIdL6wQuf2xkaW3UcmmljqUQ6dp Lp0MyBlmtiyzwF0sjkujh0B3IF2k9eXPjQ7m1l7dewfO9yAAEl+euh3ufXO5n/E= =CP28 -----END PGP SIGNATURE-----
