Does it handle near jmp's correctly as well? I.e. does it still insist on overriding the instruction to use 32-bit operands and use a 32-bit relative offset, or does it just use a 16-bit relative offset? > Bruce -- John Baldwin <jhb@FreeBSD.org> -- http://www.FreeBSD.org/~jhb/ PGP Key: http://www.cslab.vt.edu/~jobaldwi/pgpkey.asc "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
