There are two kinds of tests for the linker - some tests (e.g. TestDowncallXYZ and TestUpcallXYZ) execute end to end test with several shapes, and make sure that things work.

Then there are ABI specific tests (e.g. see TestXYZCallArranger). These latter tests are typically used to stress tests corners of specific ABIs - and they are easier to write as you can just provide the input (some function descriptor) then test that the resulting set of bindings is the expected one. This allows for much more in-depth testing.
