[PATCH v2 08/12] termios: Consolidate local mode definitions
- From: Adhemerval Zanella <adhemerval dot zanella at linaro dot org>
- To: libc-alpha at sourceware dot org
- Date: Thu, 27 Dec 2018 23:09:57 -0200
- Subject: [PATCH v2 08/12] termios: Consolidate local mode definitions
- References: <20181228011001.22260-1-adhemerval.zanella@linaro.org>
This patch consolidates the termios symbolic constants used for local
mode with c_lflag member on its own header. The Linux generic implementation
values match the kernel UAPI and each architecture with deviate values
have their own implementation (in this case alpha, mips, and powerpc).
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/Makefile (sysdep_headers): Add
termios-c_lflag.h.
* sysdeps/unix/sysv/linux/bits/termios-c_lflag.h: New file.
* sysdeps/unix/sysv/linux/alpha/bits/termios-c_lflag.h: Likewise.
* sysdeps/unix/sysv/linux/mips/bits/termios-c_lflag.h: Likewise.
* sysdeps/unix/sysv/linux/powerpc/bits/termios-c_lflag.h: Likewise.
* sysdeps/unix/sysv/linux/bits/termios.h (ISIG, ISCANON, ECHO, ECHOE,
ECHOK, ECHONL, NOFLSH, TOSTOP, IEXTEN): Move to termios-c_lflag.h.
[__USE_MISC || (__USE_XOPEN && !__USE_XOPEN2K)] (XCASE): Likewise.
[__USE_MISC] (ECHOCTL, ECHOPRT, ECHOKE, FLUSHO, PENDIN, EXTPROC):
Likewise.
* sysdeps/unix/sysv/linux/alpha/bits/termios.h: Likewise.
* sysdeps/unix/sysv/linux/mips/bits/termios.h: Likewise.
* sysdeps/unix/sysv/linux/powerpc/bits/termios.h: Likewise.
* sysdeps/unix/sysv/linux/sparc/bits/termios.h: Likewise.
