38 38 * -z dtrace=symbol assigns symbol to PT_SUNWDTRACE segment,
39 39 * providing scratch area for dtrace processing.
40 40 *
41 41 * -z noreloc suppress relocation processing. This provides
42 42 * a mechanism for validating kernel module symbol
43 43 * resolution that would normally incur fatal
44 44 * relocation errors.
45 45 *
46 46 * -z rtldinfo=symbol assigns symbol to SUNW_RTLDINF dynamic tag,
47 47 * providing pre-initialization specific routines
48 48 * for TLS initialization.
49 49 *
50 50 * -z nointerp suppress the addition of an interpreter
51 51 * section. This is used to generate the kernel,
52 52 * but makes no sense to be used by anyone else.
53 53 *
54 54 * -z norelaxreloc suppress the automatic addition of relaxed
55 55 * relocations to GNU linkonce/COMDAT sections.
56 56 *
57 57 * -z nosighandler suppress the registration of the signal handler
58 58 * used to manage SIGBUS.
