sysdeps/x86_64/dl-tlsdesc.S has
_dl_tlsdesc_resolve_rela:
cfi_adjust_cfa_offset (8)
/* Save all call-clobbered registers. */
subq $72, %rsp
cfi_adjust_cfa_offset (72)
movq %rax, (%rsp)
movq %rdi, 8(%rsp)
movq %rax, %rdi /* Pass tlsdesc* in %rdi. */
movq %rsi, 16(%rsp)
movq 72(%rsp), %rsi /* Pass link_map* in %rsi. */
movq %r8, 24(%rsp)
movq %r9, 32(%rsp)
movq %r10, 40(%rsp)
movq %r11, 48(%rsp)
movq %rdx, 56(%rsp)
movq %rcx, 64(%rsp)
call _dl_tlsdesc_resolve_rela_fixup
