From 0a07288b13c89dbbb1cac964891f5905a0919434 Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Mon, 5 Dec 2016 18:32:11 -0200 Subject: nptl: Add test cases for ISO C11 threads This patch adds to testsuite new test cases to test all new introduced C11 threads functions, types and macros are tested. Checked with a build for all major ABI (aarch64-linux-gnu, alpha-linux-gnu, arm-linux-gnueabi, i386-linux-gnu, ia64-linux-gnu, m68k-linux-gnu, microblaze-linux-gnu [1], mips{64}-linux-gnu, nios2-linux-gnu, powerpc{64le}-linux-gnu, s390{x}-linux-gnu, sparc{64}-linux-gnu, and x86_64-linux-gnu). Also ran a full check on aarch64-linux-gnu, x86_64-linux-gnu, i686-linux-gnu, arm-linux-gnueabhf, and powerpc64le-linux-gnu.
