1132 This code sequence lets the code at at the start of the PLT determine
1133 which PLT entry was executed by examining 'r29'.
1135 Note that MY_PLT_INDEX skips over the header entries, so the first
1136 actual jump table entry has index zero.
1138 If the offset fits in 16 bits,
1143 addli r28, r26, <_GLOBAL_OFFSET_TABLE_ - 1b + MY_GOT_OFFSET>
1144 moveli r27, <_GLOBAL_OFFSET_TABLE_ - 1b>

1156 For the purpose of backtracing, the procedure linkage table ends with the
1157 following tail entry:

1161 The 32-bit versions are similar, with ld4s replacing ld, and offsets into

3095 This function is responsible for adjusting the section contents as

3097 the reloc addend as necessary.
3099 This function does not have to worry about setting the reloc
