There was some discussion about this in the last thread about enabling hardfloat for PPC. See the thread: Subject: [RFC PATCH v2] target/ppc: Enable hardfloat for PPC Date: Tue, 18 Feb 2020 18:10:16 +0100 Message-Id: <20200218171702.979f0746...@zero.eik.bme.hu> However in short the problem is if the float_flag_inexact is clear you must use softfloat so you can properly calculate the inexact status. We can't take advantage of the inexact stickiness without loosing the fidelity of the calculation. -- Alex Bennée
