Global constant propagation

Hi,
In the comment at the top of gcse.c it says that the file
performs 'global constant/copy propagation', but a few
tests, plus a perusal of the code seem to indicate that
the constant/copy propagation is only done on one basic block
at a time (though the CSE is done globally as promised). Am
I right in this assessment? I am interested in adding global
constant propagation to egcs, so I am just checking that I am
not overlooking something obvious here. At the moment I am
working from the 19990314 snapshot.
