From fcb78a55058fd4e3477d9e4c6a5083d650aefa31 Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Wed, 29 Jan 2020 17:36:58 +0000 Subject: linux: Consolidate INLINE_SYSCALL With all Linux ABIs using the expected Linux kABI to indicate syscalls errors, there is no need to replicate the INLINE_SYSCALL. The generic Linux sysdep.h includes errno.h even for !__ASSEMBLER__, which is ok now and it allows cleanup some archaic code that assume otherwise. Checked with a build against all affected ABIs. --- sysdeps/unix/sysv/linux/powerpc/sysdep.h | 30 ------------------------------ 1 file changed, 30 deletions(-) (limited to 'sysdeps/unix/sysv/linux/powerpc') diff --git a/sysdeps/unix/sysv/linux/powerpc/sysdep.h b/sysdeps/unix/sysv/linux/powerpc/sysdep.h index aab4901..9442839 100644 --- a/sysdeps/unix/sysv/linux/powerpc/sysdep.h +++ b/sysdeps/unix/sysv/linux/powerpc/sysdep.h @@ -64,26 +64,6 @@ #define INTERNAL_VSYSCALL_CALL(funcptr, err, nr, args...) \ INTERNAL_VSYSCALL_CALL_TYPE(funcptr, err, long int, nr, args) -/* This version is for kernels that implement system calls that - behave like function calls as far as register saving. */ -#undef INLINE_SYSCALL -#define INLINE_SYSCALL(name, nr, args...) \ - ({ \ - INTERNAL_SYSCALL_DECL (sc_err); \ - long int sc_ret = INTERNAL_SYSCALL (name, sc_err, nr, args); \ - if (INTERNAL_SYSCALL_ERROR_P (sc_ret, sc_err)) \ - { \ - __set_errno (INTERNAL_SYSCALL_ERRNO (sc_ret, sc_err)); \ - sc_ret = -1L; \ - } \ - sc_ret; \ - }) - -/* Define a macro which expands inline into the wrapper code for a system - call.
