7318 * obtain the absolute address of the GOT, and it is strongly
7319 * preferable from a performance point of view to avoid using
7320 * a runtime relocation for this. The actual sequence of
7321 * instructions often look something like:
7322 *
7323 * call .L66
7324 * .L66:
7325 * popl %ebx
7326 * addl $_GLOBAL_OFFSET_TABLE_+[.-.L66],%ebx
7327 *
7328 * The call and pop essentially return the absolute address
7329 * of the label .L66 and store it in %ebx. The linker itself
7330 * will ultimately change the first operand of the addl so
7331 * that %ebx points to the GOT, but to keep things simple, the
7332 * .o file must have this operand set so that it generates not
7333 * the absolute address of .L66, but the absolute address of
7334 * itself. This allows the linker itself simply treat a GOTPC
7335 * relocation as asking for a pcrel offset to the GOT to be
7336 * added in, and the addend of the relocation is stored in the
7337 * operand field for the instruction itself.
7338 *
7339 * Our job here is to fix the operand so that it would add
7340 * the correct offset so that %ebx would point to itself. The
7341 * thing that is tricky is that .-.L66 will point to the
7342 * beginning of the instruction, so we need to further modify
7343 * the operand so that it will point to itself. There are
7344 * other cases where you have something like:
7345 *
7346 * .long $_GLOBAL_OFFSET_TABLE_+[.-.L66]
7347 *
7348 * and here no correction would be required. Internally in
7349 * the assembler we treat operands of this form as not being
7350 * pcrel since the '.' is explicitly mentioned, and I wonder
7351 * whether it would simplify matters to do it this way. Who
7352 * knows. In earlier versions of the PIC patches, the
7353 * pcrel_adjust field was used to store the correction, but
7354 * since the expression is not pcrel, I felt it would be
7355 * confusing to do it this way. */
