From e5a50db36eaa6e8c6427b3a971563240b633ca85 Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Tue, 9 Oct 2018 10:00:14 -0300 Subject: termios: Consolidate struct termios This patch consolidates the struct termios definition on its own header and adds arch-defined ones for ABIs that deviate from generic implementation. They are: - alpha which has a slight different layout than generic one (c_cc field is defined prior c_line). - sparc and mips which do not have the c_ispeed/c_ospeed fields. No semantic change is expected, checked on a build against x86_64-linux-gnu, alpha-linux-gnu, mips64-linux-gnu, and sparc64-linux-gnu. * sysdeps/unix/sysv/linux/alpha/bits/termios-struct.h: New file. * sysdeps/unix/sysv/linux/bits/termios-struct.h: Likewise. * sysdeps/unix/sysv/linux/mips/bits/termios-struct.h: Likewise. * sysdeps/unix/sysv/linux/sparc/bits/termios-struct.h: Likewise. * sysdeps/unix/sysv/linux/Makefile (sysdep_headers): Add termios-struct.h. * sysdeps/unix/sysv/linux/bits/termios.h (struct termios): Move to termios-struct.h. * sysdeps/unix/sysv/linux/alpha/bits/termios.h (struct termios): Likewise. * sysdeps/unix/sysv/linux/mips/bits/termios.h (struct termios): Likewise. * sysdeps/unix/sysv/linux/powerpc/bits/termios.h (struct termios): Likewise. * sysdeps/unix/sysv/linux/sparc/bits/termios.h (struct termios): Likewise. * sysdeps/unix/sysv/linux/kernel_termios.h (_HAVE_C_ISPEED, _HAVE_C_OSPEED): Define. * sysdeps/unix/sysv/linux/mips/kernel_termios.h (_HAVE_C_ISPEED, _HAVE_C_OSPEED): Likewise. * sysdeps/unix/sysv/linux/sparc/kernel_termios.h (_HAVE_C_ISPEED, _HAVE_C_OSPEED): Likewise. * sysdeps/unix/sysv/linux/speed.c [_HAVE_STRUCT_TERMIOS_C_OSPEED] (cfsetospeed): Check for define value instead of existence.
