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 --- libc/sysdeps/linux/nds32/crti.S | 24 ------------------------ 1 file changed, 24 deletions(-) (limited to 'libc/sysdeps/linux/nds32/crti.S') diff --git a/libc/sysdeps/linux/nds32/crti.S b/libc/sysdeps/linux/nds32/crti.S index 92e5e7175..61d01b63a 100644 --- a/libc/sysdeps/linux/nds32/crti.S +++ b/libc/sysdeps/linux/nds32/crti.S @@ -11,8 +11,6 @@ .type _init, @function _init: .LFB28: - !
