The /LARGEADDRESSAWARE option tells the linker that the application can handle addresses larger than 2 gigabytes. By default, /LARGEADDRESSAWARE:NO is enabled if /LARGEADDRESSAWARE is not otherwise specified on the linker line.
If an application was linked with /LARGEADDRESSAWARE, DUMPBIN /HEADERS will display information to that effect.
