Adhemerval Zanella df799d9eb3 Consolidate Linux recv implementation ... This patch consolidates the recv Linux syscall implementation on sysdeps/unix/sysv/linux/recv.c. The changes are: 1. Remove recv from auto-generation syscalls.list on the architecture that uses __NR_recv. 2. Define __NR_recv for architectures that supports it. It was done instead of defining in default kernel-features.h because current Linux practice for new ports is to implement only __NR_recvfrom [1] and it will require adding new kernel-features for ports that do not require it (aarch64 for instance). 3. Remove __ASSUME_RECVFROM_FOR_RECV_SYSCALL and decide to use __NR_recvfrom for recv generation based on __ASSUME_RECVFROM_SYSCALL. 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 recv from auto-generation list. * sysdeps/unix/sysv/linux/arm/syscalls.list: Likewise. * sysdeps/unix/sysv/linux/hppa/syscalls.list: Likewise. * sysdeps/unix/sysv/linux/ia64/syscalls.list: Likewise. * sysdeps/unix/sysv/linux/mips/syscalls.list: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc64/syscalls.list: Likewise. * sysdeps/unix/sysv/linux/alpha/kernel-features.h (__ASSUME_RECV_SYSCALL): New define. * sysdeps/unix/sysv/linux/arm/kernel-features.h (__ASSUME_RECV_SYSCALL): Likewise. * sysdeps/unix/sysv/linux/hppa/kernel-features.h (__ASSUME_RECV_SYSCALL): Likewise. * sysdeps/unix/sysv/linux/ia64/kernel-features.h (__ASSUME_RECV_SYSCALL): Likewise. * sysdeps/unix/sysv/linux/mips/kernel-features.h (__ASSUME_RECV_SYSCALL): Likewise. * sysdeps/unix/sysv/linux/i386/kernel-features.h (__ASSUME_RECVFROM_FOR_RECV_SYSCALL): Remove define. * sysdeps/unix/sysv/linux/m68k/kernel-features.h (__ASSUME_RECVFROM_FOR_RECV_SYSCALL): Remove define. * sysdeps/unix/sysv/linux/s390/kernel-features.h (__ASSUME_RECVFROM_FOR_RECV_SYSCALL): Remove define. * sysdeps/unix/sysv/linux/generic/recv.c: Remove file. * sysdeps/unix/sysv/linux/mips/mips64/recv.c: Likewise. * sysdeps/unix/sysv/linux/x86_64/recv.c: Likewise. * sysdeps/unix/sysv/linux/recv.c: Simplify includes. (__libc_recv): Use __ASSUME_RECVFROM_SYSCALL instead of __ASSUME_RECVFROM_FOR_RECV_SYSCALL to issue recvfrom syscall.
