C++ (Cpp) CMPUNORDSS Beispiele

Beispiel #1

Datei: CompFPU.cpp Projekt: ANR2ME/ppsspp

void Jit::CompFPComp(int lhs, int rhs, u8 compare, bool allowNaN)
{
	gpr.MapReg(MIPS_REG_FPCOND, false, true);
	MOVSS(XMM0, fpr.R(lhs));
	CMPSS(XMM0, fpr.R(rhs), compare);
	MOVD_xmm(gpr.R(MIPS_REG_FPCOND), XMM0);

	// This means that NaN also means true, e.g. !<> or !>, etc.
	if (allowNaN)
	{
		MOVSS(XMM0, fpr.R(lhs));
		CMPUNORDSS(XMM0, fpr.R(rhs));

		MOVD_xmm(R(EAX), XMM0);
		OR(32, gpr.R(MIPS_REG_FPCOND), R(EAX));
	}
}
