However they should all return # to C with the value in r1 restored, so I think it's legitimate to say # r1 is not clobbered. # # As Segher points out, the r1 clobbers may have been added because of # the use of `or 1,1,1`, however that doesn't actually clobber r1. # # Segher also points out that some of these tests do clobber LR, because # they call functions, and that is not listed in the clobbers, so add # that where appropriate. # # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/20191029095324.14669-1-mpe@ellerman.id.au # <
