gimple_replace_ssa_lhs()

void gimple_replace_ssa_lhs ( gimple * stmt, tree nlhs )

extern

Replace the LHS of STMT, an assignment, either a GIMPLE_ASSIGN or a
GIMPLE_CALL, with NLHS, in preparation for modifying the RHS to an
expression with a different value.

This will update any annotations (say debug bind stmts) referring
to the original LHS, so that they use the RHS instead.  This is
done even if NLHS and LHS are the same, for it is understood that
the RHS will be modified afterwards, and NLHS will not be assigned
an equivalent value.

Adjusting any non-annotation uses of the LHS, if needed, is a
responsibility of the caller.

The effect of this call should be pretty much the same as that of
inserting a copy of STMT before STMT, and then removing the
original stmt, at which time gsi_remove() would have update
annotations, but using this function saves all the inserting,
copying and removing.
