This is the runtime optimisation where the first call to __tls_get_addr results in __tls_get_addr updating the tls_index pair, then the special linker stub using that to short-circuit second and subsequent calls for a given tls symbol. Enabled by default when the linker sees __tls_get_addr_opt is preseent, and enabled in ld.so when DT_PPC64_OPT has PPC64_OPT_TLS set. Note that this is distinct from link-time tls optimisation. PR 32387 * elf64-ppc.c (ppc64_elf_check_relocs): Disable tls_get_addr_opt on detecting inline plt calls to __tls_get_addr. -- You are receiving this mail because: You are on the CC list for the bug.
