From 7c3eed786021ede69394fe371c9e7c8bd603f5a8 Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Tue, 4 Jun 2019 17:29:42 +0000 Subject: mips: Consolidate INTERNAL_VSYSCALL_CALL This patch consolidates the mips, mips64, and mips64-n32 INTERNAL_VSYSCALL_CALL on a single implementation. No semantic changes. I checked against a build for mips-linux-gnu, mips64-linux-gnu, and mips64-n32-linux-gnu. * sysdeps/unix/sysv/linux/mips/mips32/sysdep.h (INTERNAL_VSYSCALL_CALL): Remove. * sysdeps/unix/sysv/linux/mips/mips64/n32/sysdep.h (INTERNAL_VSYSCALL_CALL): Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n64/sysdep.h (INTERNAL_VSYSCALL_CALL): Likewise. * sysdeps/unix/sysv/linux/mips/sysdep.h (INTERNAL_VSYSCALL_CALL): New macro. --- sysdeps/unix/sysv/linux/mips/mips32/sysdep.h | 12 ------------ sysdeps/unix/sysv/linux/mips/mips64/n32/sysdep.h | 12 ------------ sysdeps/unix/sysv/linux/mips/mips64/n64/sysdep.h | 12 ------------ sysdeps/unix/sysv/linux/mips/sysdep.h | 16 ++++++++++++++++ 4 files changed, 16 insertions(+), 36 deletions(-) (limited to 'sysdeps') diff --git a/sysdeps/unix/sysv/linux/mips/mips32/sysdep.h b/sysdeps/unix/sysv/linux/mips/mips32/sysdep.h index 09d9040..86347fe 100644 --- a/sysdeps/unix/sysv/linux/mips/mips32/sysdep.h +++ b/sysdeps/unix/sysv/linux/mips/mips32/sysdep.h @@ -349,18 +349,6 @@ libc_hidden_proto (__mips_syscall7, nomips16) #define __SYSCALL_CLOBBERS "$1", "$3", "$8", "$9", "$10", "$11", "$12", "$13", \ "$14", "$15", "$24", "$25", "hi", "lo", "memory" -/* Standard MIPS syscalls have an error flag, and return a positive errno - when the error flag is set.
