62  * to the offset to the plt entry in %g1 to calculate the plt entry address
157  * Initialize a plt entry so that function calls go to 'bindfunc'
162  * The plt entries (PLT0 and PLT1) look like:
192 elf_plt_init(void *plt, caddr_t bindfunc)
196 	_plt = (uint_t *)plt;
213 	st	%o0, [%i0]		! Store in plt[0]
218 	st	%o4, [%i0 + 0x4]	! Store instruction in plt[1]
224 	st	%o4, [%i0 + 0x8]	! Store instruction in plt[2]

284  * After the first call to a plt, elf_bndr() will have determined the true
285  * address of the function being bound.  The plt is now rewritten so that
289  * For complete 64-bit spanning, the new plt entry is:
