// Verify the behavior of the +gfxN-insts in the way that
// rocm-device-libs should be built with. e.g. If the device libraries has a function
// with "+gfx11-insts", that attribute should still be present after linking and not
// overwritten with the current target's settings.

// This is important because at this time, many device-libs functions that are only
// available on some GPUs put an attribute such as "+gfx11-insts" so that
// AMDGPURemoveIncompatibleFunctions can detect & remove them if needed.

// Build the fake device library in the way rocm-device-libs should be built.
