157 /* There are many kinds of PLT entries:
159 (1) A direct jump to the actual routine, either a relative or
160 absolute branch. These are set up in __elf_machine_fixup_plt.
162 (2) Short lazy entries. These cover the first 8192 slots in
163 the PLT, and look like (where 'index' goes from 0 to 8191):
166 b &plt[PLT_TRAMPOLINE_ENTRY_WORDS+1]
168 (3) Short indirect jumps. These replace (2) when a direct jump
169 wouldn't reach. They look the same except that the branch
170 is 'b &plt[PLT_LONGBRANCH_ENTRY_WORDS]'.
172 (4) Long lazy entries. These cover the slots when a short entry
173 won't fit ('index*4' overflows its field), and look like:
175 lis %r11, %hi(index*4 + &plt[PLT_DATA_START_WORDS])
176 lwzu %r12, %r11, %lo(index*4 + &plt[PLT_DATA_START_WORDS])
177 b &plt[PLT_TRAMPOLINE_ENTRY_WORDS]
180 (5) Long indirect jumps. These replace (4) when a direct jump
181 wouldn't reach. They look like:
183 lis %r11, %hi(index*4 + &plt[PLT_DATA_START_WORDS])
184 lwz %r12, %r11, %lo(index*4 + &plt[PLT_DATA_START_WORDS])
188 (6) Long direct jumps. These are used when thread-safety is not
189 required. They look like:
191 lis %r12, %hi(finaladdr)
192 addi %r12, %r12, %lo(finaladdr)
197 The lazy entries, (2) and (4), are set up here in
198 __elf_machine_runtime_setup. (1), (3), and (5) are set up in
199 __elf_machine_fixup_plt. (1), (3), and (6) can also be constructed
200 in __process_machine_rela.
202 The reason for the somewhat strange construction of the long
203 entries, (4) and (5), is that we need to ensure thread-safety. For
204 (1) and (3), this is obvious because only one instruction is
205 changed and the PPC architecture guarantees that aligned stores are
206 atomic. For (5), this is more tricky. When changing (4) to (5),
207 the `b' instruction is first changed to `mtctr'; this is safe
208 and is why the `lwzu' instruction is not just a simple `addi'.
209 Once this is done, and is visible to all processors, the `lwzu' can
210 safely be changed to a `lwz'. */
