1 # This test checks that we have a mapping between the B registers and their Codeview numbers.
2 # There is no 8 bit float type so this is a modified version of codeview-h-register.mir to
3 # have a B register in the location info but not the instructions. Which is incorrect
4 # but in ways this test does not care about.
