% This is a regression test for a bug in liveness.m.
|
|
%
|
|
% When stuffing liveness residues after goals, which we do for variables
|
|
% which are nondet-live in one arm of a branched goal but not in the other,
|
|
% make sure that we do not add post-births for variables that are already live
|
|
% at the end of the goal that we are doing the stuffing into. (If we do that,
|
|
% then the compiler assumes that they have become automagically live, and
|
|
% so just assumes they are in some random register.)
