Subject: Fix warnings from ARM soft-float fpu_control.h
Date: Tue, 18 Jun 2013 00:37:00 -0000 [thread overview]
Message-ID: <Pine.LNX.4.64.1306180035390.15498@digraph.polyomino.org.uk> (raw)
I've applied this patch to make the ARM soft-float fpu_control.h
definitions of _FPU_GETCW and _FPU_SETCW match those used in other
soft-float cases, to avoid them generating compiler warnings (in
particular, when building the test-fpucw.c testcase).
