From 6af3332a4cbd1ffbc81f74759ef7c5e1a87d2e10 Mon Sep 17 00:00:00 2001 From: Vincent Ren-Wei Chen Date: Tue, 17 Jan 2017 07:31:24 +0100 Subject: nds32: add NPTL/TLS, *context function, libm changes and code cleanup This commit includes following features. 1. Support NPTL/TLS 2. Add libm function which is used to handle FP rounding and excpetions (ex: fclrexcpt,fedisblxcpti,feenablxcpt... ) 3. Add *context function for operating user context (ex: setcontext,getcontext,makecontext... ) 4. Change the return flow from signal handler 5. Cleanup of old code The testsuite only has 2 errors, tst-cpuclock1 and tst-cputimer1, which are related to timing accuracy. (math and locale tests are disabled) Signed-off-by: Vincent Ren-Wei Chen --- .../nptl/sysdeps/unix/sysv/linux/nds32/fork.c | 27 ++++++++++++++++++++++ 1 file changed, 27 insertions(+) create mode 100644 libpthread/nptl/sysdeps/unix/sysv/linux/nds32/fork.c (limited to 'libpthread/nptl/sysdeps/unix/sysv/linux/nds32/fork.c') diff --git a/libpthread/nptl/sysdeps/unix/sysv/linux/nds32/fork.c b/libpthread/nptl/sysdeps/unix/sysv/linux/nds32/fork.c new file mode 100644 index 000000000..beb6cb0f7 --- /dev/null +++ b/libpthread/nptl/sysdeps/unix/sysv/linux/nds32/fork.c @@ -0,0 +1,27 @@ +/* Copyright (C) 2005 Free Software Foundation, Inc. + Contributed by Phil Blundell , 2005 + + The GNU C Library is free software; you can redistribute it and/or + modify it under the terms of the GNU Lesser General Public + License as published by the Free Software Foundation; either + version 2.1 of the License, or (at your option) any later version. + + The GNU C Library is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
