From af5fdf5a358329161cc3960f5e54fac16dbb8063 Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Mon, 11 Apr 2016 15:07:12 -0300 Subject: Consolidate pwritev/pwritev64 implementations This patch consolidates all the pwritev{64} implementation for Linux in only one (sysdeps/unix/sysv/linux/pwritev{64}.c). It also removes the syscall from the auto-generation using assembly macros. It was based on previous pwrite/pwrite64 consolidation patch. The new macro SYSCALL_LL{64} is used to handle the offset argument and alias is created for __ASSUME_OFF_DIFF_OFF64 in case of pread64. Checked on x86_64, i386, aarch64, and powerpc64le. * misc/Makefile (CFLAGS-pwritev.c): New variable: add cancellation required flags. (CFLAGS-pwritev64.c): Likewise. * sysdeps/unix/sysv/linux/generic/wordsize-32/pwritev.c: Remove file. * sysdeps/unix/sysv/linux/generic/wordsize-32/pwritev64.c: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n64/pwritev64.c: Likewise. * sysdeps/unix/sysv/linux/wordsize-64/pwritev.c: Likewise. * sysdeps/unix/sysv/linux/wordsize-64/pwritev64.: Likwise. * sysdeps/unix/sysv/linux/x86_64/x32/syscalls.list (pwritev): Remove syscall from auto-generation. * sysdeps/unix/sysv/linux/pwritev.c: Rewrite implementation. [WORDSIZE == 64] (pwritev64): Remove macro. [!PWRITEV] (PWRITEV): Likewise. [!PWRITEV] (PWRITEV_REPLACEMENT): Likewise. [!PWRITEV] (PWRITE): Likewise. [!PWRITEV] (OFF_T): Likewise. [!__ASSUME_PWRITEV] (PWRITEV_REPLACEMENT): Likewise. (LO_HI_LONG): Remove macro. [__WORDSIZE != 64 || __ASSUME_OFF_DIFF_OFF64] (pwritev): Add function. * sysdeps/unix/sysv/linux/pwritev64.c: Rewrite implementation. (PWRITEV): Remove macro. (PWRITEV_REPLACEMENTE): Likewise. (PWRITE): Likewise. (OFF_T): Likewise. (pwritev64): New function. * nptl/tst-cancel4.c (tf_writev): Add test. --- misc/Makefile | 2 ++ 1 file changed, 2 insertions(+) (limited to 'misc/Makefile') diff --git a/misc/Makefile b/misc/Makefile index 658d4baeed..6498adc3aa 100644 --- a/misc/Makefile +++ b/misc/Makefile @@ -90,6 +90,8 @@ CFLAGS-readv.c = -fexceptions -fasynchronous-unwind-tables CFLAGS-writev.c = -fexceptions -fasynchronous-unwind-tables CFLAGS-preadv.c = -fexceptions -fasynchronous-unwind-tables CFLAGS-preadv64.c = -fexceptions -fasynchronous-unwind-tables +CFLAGS-pwritev.c = -fexceptions -fasynchronous-unwind-tables +CFLAGS-pwritev64.c = -fexceptions -fasynchronous-unwind-tables CFLAGS-usleep.c = -fexceptions CFLAGS-syslog.c = -fexceptions CFLAGS-error.c = -fexceptions -- cgit 1.4.1
