From f1ecb7ef7f5703fc156b8ab2ca153d774c39ec7a Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Sat, 6 Oct 2012 18:36:40 -0700 Subject: Fix Niagara-4 memcpy bug on 32-bit. * sysdeps/sparc/sparc64/multiarch/memcpy-niagara4.S: On 32-bit, clear upper 32-bits of the length value in %o2 since we use branch-on-register tests which consider the entire 64-bit register. --- sysdeps/sparc/sparc64/multiarch/memcpy-niagara4.S | 3 +++ 1 file changed, 3 insertions(+) (limited to 'sysdeps') diff --git a/sysdeps/sparc/sparc64/multiarch/memcpy-niagara4.S b/sysdeps/sparc/sparc64/multiarch/memcpy-niagara4.S index 7bb05b9818..3da98a87ab 100644 --- a/sysdeps/sparc/sparc64/multiarch/memcpy-niagara4.S +++ b/sysdeps/sparc/sparc64/multiarch/memcpy-niagara4.S @@ -64,6 +64,9 @@ ENTRY(__memcpy_niagara4) 100: /* %o0=dst, %o1=src, %o2=len */ mov %o0, %o3 101: +#ifndef __arch64__ + srl %o2, 0, %o2 +#endif brz,pn %o2, .Lexit cmp %o2, 3 ble,pn %icc, .Ltiny -- cgit v1.2.3
