From 48dbce60cfdd328b671aaa9ee0c54ded3246ece9 Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Mon, 4 Nov 2019 13:36:05 +0000 Subject: nptl: Add tests for internal pthread_rwlock_t offsets This patch new build tests to check for internal fields offsets for internal pthread_rwlock_t definition. Althoug the '__data.__flags' field layout should be preserved due static initializators, the patch also adds tests for the futexes that may be used in a shared memory (although using different libc version in such scenario is not really supported). Checked with a build against all affected ABIs.
