From d017b0ab5a181dce4145f3a1b3b27e3341abd201 Mon Sep 17 00:00:00 2001 From: Florian Weimer Date: Mon, 10 May 2021 10:31:41 +0200 Subject: elf: Introduce __tls_pre_init_tp This is an early variant of __tls_init_tp, primarily for initializing thread-related elements of _rtld_global/GL. Some existing initialization code not needed for NPTL is moved into the generic version of this function.
