From 0b6eb2dfb2e84a8a51906e7634f3d5edc230b058 Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Wed, 21 Sep 2011 20:11:10 -0400 Subject: update syscalls with off_t arguments to handle argument alignment, if needed the arm syscall abi requires 64-bit arguments to be aligned on an even register boundary. these new macros facilitate meeting the abi requirement without imposing significant ugliness on the code. --- arch/arm/bits/syscall.h | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'arch/arm') diff --git a/arch/arm/bits/syscall.h b/arch/arm/bits/syscall.h index 380ac3ca..b0379e02 100644 --- a/arch/arm/bits/syscall.h +++ b/arch/arm/bits/syscall.h @@ -1,6 +1,7 @@ -#define __SYSCALL_LL(x) \ +#define __SYSCALL_LL_E(x) \ ((union { long long ll; long l[2]; }){ .ll = x }).l[0], \ ((union { long long ll; long l[2]; }){ .ll = x }).l[1] +#define __SYSCALL_LL_O(x) 0, __SYSCALL_LL_E((x)) long (__syscall)(long, ...); -- cgit v1.2.1
