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 --- libpthread/nptl/sysdeps/nds32/dl-tls.h | 59 ++++++++++++++++++++++++++++++++++ 1 file changed, 59 insertions(+) create mode 100644 libpthread/nptl/sysdeps/nds32/dl-tls.h (limited to 'libpthread/nptl/sysdeps/nds32/dl-tls.h') diff --git a/libpthread/nptl/sysdeps/nds32/dl-tls.h b/libpthread/nptl/sysdeps/nds32/dl-tls.h new file mode 100644 index 000000000..3b11e7f42 --- /dev/null +++ b/libpthread/nptl/sysdeps/nds32/dl-tls.h @@ -0,0 +1,59 @@ +/* Thread-local storage handling in the ELF dynamic linker.
