        lui     a5,%hi(.LANCHOR0)
        addi    a5,a5,%lo(.LANCHOR0)
        lw      a4,4(a5)

# 16 "test.cpp" 1

_Z5pcnt0v:

        lui     a5,%hi(.LANCHOR0+4)
        lw      a0,%lo(.LANCHOR0+4)(a5)


>From GCC point of view this is correct as GCC does not know if %hi(.LANCHOR0+4)
== %hi(.LANCHOR0)
