[PATCH 4.14 16/51] parisc: Fix compiler warnings in float emulation code
From: Greg Kroah-Hartman
Date: Mon Jun 24 2019 - 06:01:57 EST
[ Upstream commit 6b98d9134e14f5ef4bcf64b27eedf484ed19a1ec ]
Avoid such compiler warnings:
arch/parisc/math-emu/cnv_float.h:71:27: warning: â<<â in boolean context, did you mean â<â ? [-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 âDint_isinexact_to_sglâ
if (Dint_isinexact_to_sgl(srcp1,srcp2)) {
