Subject: [PATCH AUTOSEL 4.19 10/39] parisc: Fix compiler warnings in float emulation code
Date: Fri, 14 Jun 2019 16:29:15 -0400 [thread overview]
Message-ID: <20190614202946.27385-10-sashal@kernel.org> (raw)
In-Reply-To: <20190614202946.27385-1-sashal@kernel.org>

[ Upstream commit 6b98d9134e14f5ef4bcf64b27eedf484ed19a1ec ]
Avoid such compiler warnings:
arch/parisc/math-emu/cnv_float.h:71:27: warning: ‘<<’ in boolean context, did you mean ‘<’ ? [-Wint-in-bool-context]
((Dintp1(dint_valueA) << 33 - SGL_EXP_LENGTH) || Dintp2(dint_valueB))
arch/parisc/math-emu/fcnvxf.c:257:6: note: in expansion of macro ‘Dint_isinexact_to_sgl’
if (Dint_isinexact_to_sgl(srcp1,srcp2)) {
