Although this option can be used alone, it is part of the expansion of the -xtarget option and may be used to override the –xarch value that is set by a specific -xtarget option. For example, -xtarget=ultra2 expands to -xarch=v8plusa -xchip=ultra2 -xcache=16/32/1:512/64/1. In the following command -xarch=v8plusb overrides the -xarch=v8plusa that is set by the expansion of -xtarget=ultra2.

Use of –compat[=4] with -xarch=generic64, -xarch=native64, -xarch=v9, -xarch=v9a, or -xarch=v9b is not supported.
