38 * -z dtrace=symbol assigns symbol to PT_SUNWDTRACE segment,

41 * -z noreloc suppress relocation processing. This provides
42 * a mechanism for validating kernel module symbol

44 * relocation errors.
45 *
46 * -z rtldinfo=symbol assigns symbol to SUNW_RTLDINF dynamic tag,
47 * providing pre-initialization specific routines
48 * for TLS initialization.
49 *
50 * -z nointerp suppress the addition of an interpreter
51 * section. This is used to generate the kernel,
52 * but makes no sense to be used by anyone else.
53 *
54 * -z norelaxreloc suppress the automatic addition of relaxed
55 * relocations to GNU linkonce/COMDAT sections.
