From 1f8161a801b2292a58f3036ea92aa7feeafc10f2 Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Mon, 6 Mar 2017 12:53:14 +0100 Subject: Consolidate Linux recvfrom implementation This patch consolidates the recvfrom Linux syscall implementation on sysdeps/unix/sysv/linux/recvfrom.c. The changes are: 1. Define __ASSUME_RECVFROM_SYSCALL by default 2. Undef it for architectures that do not support __NR_recvfrom. Checked on i686-linux-gnu, x86_64-linux-gnu, x86_64-linux-gnux32, aarch64-linux-gnu, arm-linux-gnueabihf, and powerpc64le-linux-gnu. * sysdeps/unix/sysv/linux/alpha/syscalls.list: Remove recvfrom from auto-generation list. * sysdeps/unix/sysv/linux/arm/syscalls.list: Likewise. * sysdeps/unix/sysv/linux/generic/syscalls.list: Likewise. * sysdeps/unix/sysv/linux/hppa/syscalls.list: Likewise. * sysdeps/unix/sysv/linux/ia64/syscalls.list: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc64/syscalls.list: Likewise. * sysdeps/unix/sysv/linux/x86_64/syscalls.list: Likewise. * sysdeps/unix/sysv/linux/mips/syscalls.list: Likewise. * sysdeps/unix/sysv/linux/i386/kernel-features.h * sysdeps/unix/sysv/linux/kernel-features.h (__ASSUME_RECVFROM_SYSCALL): Define by default.
