From 3feb647f3fd0881382c7a29f4cf280b66473ae0a Mon Sep 17 00:00:00 2001 From: Sergei Poselenov Date: Tue, 4 Nov 2008 13:51:18 +0100 Subject: [PATCH] Add a do_div() wrapper macro, lldiv(). Add a do_div() wrapper, lldiv(). The new inline function doesn't modify the dividend and returns the result of division, so it is useful in complex expressions, i.e. "return(a/b)" -> "return(lldiv(a,b))" Signed-off-by: Sergei Poselenov --- include/div64.h | 10 ++++++++++ 1 file changed, 10 insertions(+) diff --git a/include/div64.h b/include/div64.h index c495aefb01..d83314435d 100644 --- a/include/div64.h +++ b/include/div64.h @@ -36,4 +36,14 @@ extern uint32_t __div64_32(uint64_t *dividend, uint32_t divisor); __rem; \ }) +/* Wrapper for do_div().
