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/microblaze/sysdep.h | 25 +------------------------ 1 file changed, 1 insertion(+), 24 deletions(-) (limited to 'sysdeps/unix/sysv/linux/microblaze/sysdep.h') diff --git a/sysdeps/unix/sysv/linux/microblaze/sysdep.h b/sysdeps/unix/sysv/linux/microblaze/sysdep.h index 796663a..8f9355f 100644 --- a/sysdeps/unix/sysv/linux/microblaze/sysdep.h +++ b/sysdeps/unix/sysv/linux/microblaze/sysdep.h @@ -60,6 +60,7 @@ /* We don't want the label for the error handler to be visible in the symbol table when we define it here. */ +# undef SYSCALL_ERROR_LABEL # ifdef PIC # define SYSCALL_ERROR_LABEL 0f # else @@ -163,23 +164,6 @@ SYSCALL_ERROR_LABEL_DCL: \ #else /* not __ASSEMBLER__ */ -/* Define a macro which expands into the inline wrapper code for a system - call. */ -# undef INLINE_SYSCALL -# define INLINE_SYSCALL(name, nr, args...) \ -({ INTERNAL_SYSCALL_DECL(err); \ - unsigned long resultvar = INTERNAL_SYSCALL(name, err, nr, args); \ - if (INTERNAL_SYSCALL_ERROR_P (resultvar, err)) \ - { \ - __set_errno (INTERNAL_SYSCALL_ERRNO (resultvar, err)); \ - resultvar = (unsigned long) -1; \ - } \ - (long) resultvar; \ -}) - -# undef INTERNAL_SYSCALL_DECL -# define INTERNAL_SYSCALL_DECL(err) do { } while (0) - /* Define a macro which expands inline into the wrapper code for a system call.
