// Description:

// file timelegacyapis.cpp

// This executable times how long it takes to call legacy APIs. It should be used when 

// new hardware build targets are introduced. The existing performance tests can then be 

// updated for these platforms.

// Note: The times generated can be used for the following tests:

// - PrintSWVersionAPILegacyTimes					SYSLIB-BAFL-CT-4064

// - PrintLangVersionAPILegacyTimes				SYSLIB-BAFL-CT-4065

// - PrintLangSWVersionAPILegacyTimes				SYSLIB-BAFL-CT-4066
