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. --- libc/sysdeps/linux/nios2/bits/fcntl.h | 6 +- libc/sysdeps/linux/nios2/bits/kernel_stat.h | 50 -------- libc/sysdeps/linux/nios2/bits/kernel_types.h | 6 +- libc/sysdeps/linux/nios2/bits/setjmp.h | 30 +---- libc/sysdeps/linux/nios2/bits/stat.h | 167 -------------------------- libc/sysdeps/linux/nios2/bits/syscalls.h | 173 +++++++++++++-------------- 6 files changed, 95 insertions(+), 337 deletions(-) delete mode 100644 libc/sysdeps/linux/nios2/bits/kernel_stat.h delete mode 100644 libc/sysdeps/linux/nios2/bits/stat.h (limited to 'libc/sysdeps/linux/nios2/bits') diff --git a/libc/sysdeps/linux/nios2/bits/fcntl.h b/libc/sysdeps/linux/nios2/bits/fcntl.h index d8386d65c..4fe1ee396 100644 --- a/libc/sysdeps/linux/nios2/bits/fcntl.h +++ b/libc/sysdeps/linux/nios2/bits/fcntl.h @@ -44,9 +44,9 @@ #define O_ASYNC 020000 #ifdef __USE_GNU -# define O_DIRECTORY 040000 /* Must be a directory. */ -# define O_NOFOLLOW 0100000 /* Do not follow links. */ -# define O_DIRECT 0200000 /* Direct disk access. */ +# define O_DIRECTORY 0200000 /* Must be a directory. */ +# define O_NOFOLLOW 0400000 /* Do not follow links. */ +# define O_DIRECT 040000 /* Direct disk access. */ # define O_NOATIME 01000000 /* Do not set atime. */ # define O_CLOEXEC 02000000 /* set close_on_exec */ # define O_PATH 010000000 /* Resolve pathname but do not open file. */ diff --git a/libc/sysdeps/linux/nios2/bits/kernel_stat.h b/libc/sysdeps/linux/nios2/bits/kernel_stat.h deleted file mode 100644 index 99a6cba97..000000000 --- a/libc/sysdeps/linux/nios2/bits/kernel_stat.h +++ /dev/null @@ -1,50 +0,0 @@ -#ifndef _BITS_STAT_STRUCT_H -#define _BITS_STAT_STRUCT_H - -/* This file provides whatever this particular arch's kernel thinks - * struct kernel_stat should look like...
