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/sigaction.c | 40 ------------------------------------ 1 file changed, 40 deletions(-) delete mode 100644 libc/sysdeps/linux/nds32/sigaction.c (limited to 'libc/sysdeps/linux/nds32/sigaction.c') diff --git a/libc/sysdeps/linux/nds32/sigaction.c b/libc/sysdeps/linux/nds32/sigaction.c deleted file mode 100644 index 1a24c49b4..000000000 --- a/libc/sysdeps/linux/nds32/sigaction.c +++ /dev/null @@ -1,40 +0,0 @@ -/* - * Copyright (C) 2016 Andes Technology, Inc. - * Licensed under the LGPL v2.1, see the file COPYING.LIB in this tarball. - */ - -#include -#include -#include -#include -#include - -#define SA_RESTORER 0x04000000 - -extern void __default_sa_restorer(void); - -int __libc_sigaction(int sig, const struct sigaction *act, - struct sigaction *oact) -{ - struct sigaction kact; - - if (act && !(act->sa_flags & SA_RESTORER)) { - memcpy(&kact, act, sizeof(kact)); - kact.sa_restorer = __default_sa_restorer; - kact.sa_flags |= SA_RESTORER; - act = &kact; - } - /* NB: kernel (as of 2.6.25) will return EINVAL - * if sizeof(act->sa_mask) does not match kernel's sizeof(sigset_t) */ - return __syscall_rt_sigaction(sig, act, oact, sizeof(act->sa_mask)); -} - -#ifndef LIBC_SIGACTION -# ifndef __UCLIBC_HAS_THREADS__ -strong_alias(__libc_sigaction,sigaction) -libc_hidden_def(sigaction) -# else -weak_alias(__libc_sigaction,sigaction) -libc_hidden_weak(sigaction) -# endif -#endif -- cgit v1.2.3
