This is sort of backwards. Xsyscall is supposed to be named like the C function syscall(), but it should be used for normal int 0x80 syscalls. > - Reduce code duplication between the int0x80 and lcall handlers by > shuffling the elfags into the right place, saving the sizeof the > instruction in tf_err and jumping into the common int0x80 code. This breaks profiling and pessimizes Xsyscall a little. Please back this out. Bruce To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
