From b8fcdddcbb192fc367ff04bbd753b9deb69b09f3 Mon Sep 17 00:00:00 2001 From: Waldemar Brodkorb Date: Sat, 28 May 2016 18:12:58 +0200 Subject: nios2: sync support with glibc Only static linking is supported for now. More debugging and analyzing for ld.so, TLS and NPTL is required. But at least you can bootup a static root fileystem in Qemu. --- libpthread/nptl/sysdeps/nios2/libc-tls.c | 32 ++++++++++++++++++++++++++++++++ 1 file changed, 32 insertions(+) create mode 100644 libpthread/nptl/sysdeps/nios2/libc-tls.c (limited to 'libpthread/nptl/sysdeps/nios2/libc-tls.c') diff --git a/libpthread/nptl/sysdeps/nios2/libc-tls.c b/libpthread/nptl/sysdeps/nios2/libc-tls.c new file mode 100644 index 000000000..d677979ed --- /dev/null +++ b/libpthread/nptl/sysdeps/nios2/libc-tls.c @@ -0,0 +1,32 @@ +/* Thread-local storage handling in the ELF dynamic linker.
