55	"#pragma optimize("""", off) in JEM7.0"	anjicheng		"In the JEM7.0, the following code is added in the “TComTrQuant.cpp”
 
#if 1800 < _MSC_VER && _MSC_VER < 2000
#pragma optimize("""", off)
#endif
 
The macro value “_MSC_VER”= 1900 for visual studio 2015. So for the VS2015, the above code makes the encoding time double for AI, and around 20-30% higher for RA and LD configurations.
Maybe the purpose of that code is to prevent some potential compiler failure for VS2015. But for our VS2015, there is no problem found to remove that code. So, if you use VS2015, you may try to speedup JEM7.0 by remove that code."	defect	closed	minor	HM-16.6-JEM-7.1	JEM	HM-16.6-JEM-7.0	fixed	"#pragma optimize("""", off)"	ksuehring XiangLi jvet@…
