From: Rich Felker Date: Mon, 25 Mar 2013 15:34:22 +0000 (-0400) Subject: in pipe2, use pipe() rather than __syscall(SYS_pipe, ...) for fallback X-Git-Tag: v0.9.10~47 X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=ae7399bfd86c59b8717bb81c70b2acb20acd0f9a;p=oweals%2Fmusl.git in pipe2, use pipe() rather than __syscall(SYS_pipe, ...) for fallback SYS_pipe is not usable directly in general, since mips has a very broken calling convention for the pipe syscall. instead, just call the function, so that the mips-specific ugliness is isolated in mips/pipe.s and not copied elsewhere. --- diff --git a/src/unistd/pipe2.c b/src/unistd/pipe2.c index bbeabcbf..f24f74fb 100644 --- a/src/unistd/pipe2.c +++ b/src/unistd/pipe2.c @@ -5,11 +5,11 @@ int pipe2(int fd[2], int flag) { - if (!flag) return syscall(SYS_pipe, fd); + if (!flag) return pipe(fd); int ret = __syscall(SYS_pipe2, fd, flag); if (ret != -ENOSYS) return __syscall_ret(ret); - ret = __syscall(SYS_pipe, fd); - if (ret) return __syscall_ret(ret); + ret = pipe(fd); + if (ret) return ret; if (flag & O_CLOEXEC) { __syscall(SYS_fcntl, fd[0], F_SETFD, FD_CLOEXEC); __syscall(SYS_fcntl, fd[1], F_SETFD, FD_CLOEXEC);
