The attached and committed patch updates gfortran
expression dumper to do something sensible with a
gfc_expr that is a BT_BOZ basic type. That is, for
program a
real :: x = real(b'10101')
real :: y = real(o'4444')
real :: z = real(z'abcd')
print *, x, y, z
end program a
if one is in gdb, you now get (in gfc_boz2real).
(gdb) call debug(x)
b'10101' (BOZ 0)
(gdb) call debug(x)
o'4444' (BOZ 0)
(gdb) call debug(x)
z'abcd' (BOZ 0)
