From 8dbeb0561eeb876f557ac9eef5721912ec074ea5 Mon Sep 17 00:00:00 2001 From: Florian Weimer Date: Thu, 9 Dec 2021 09:49:32 +0100 Subject: nptl: Add for defining __thread_pointer already contains a definition that is quite similar, but it is not consistent across architectures. Only architectures for which rseq support is added are covered.
