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/mremap.c | 28 ++++++++++++++++++++++++++++ 1 file changed, 28 insertions(+) create mode 100644 libc/sysdeps/linux/nds32/mremap.c (limited to 'libc/sysdeps/linux/nds32/mremap.c') diff --git a/libc/sysdeps/linux/nds32/mremap.c b/libc/sysdeps/linux/nds32/mremap.c new file mode 100644 index 000000000..9b2d83544 --- /dev/null +++ b/libc/sysdeps/linux/nds32/mremap.c @@ -0,0 +1,28 @@ +/* + * Copyright (C) 2017 Andes Technology, Inc. + * Licensed under the LGPL v2.1, see the file COPYING.LIB in this tarball. + */ + +#include +#include +#include + +#include +#include + +#ifdef __NR_mremap +void *mremap (void *__addr, size_t __old_len, size_t __new_len, + int __flags, ...); +libc_hidden_proto(mremap) + +void *mremap (void *__addr, size_t __old_len, size_t __new_len, int __flags, ...) +{ + unsigned long arg1; + va_list arg; + va_start (arg, __flags); + arg1 = va_arg (arg, int); + va_end (arg); + return (void *)INLINE_SYSCALL(mremap,5,__addr,__old_len,__new_len,__flags,arg1); +} +libc_hidden_def (mremap) +#endif -- cgit v1.2.3
