Some code I added for the ptx backend triggered tree-checking failures
for gimple created in tree-nested: we can end up taking the address of
an SSA_NAME, which seems invalid. The problem is that code in
tree-nested wants to change the rhs of an existing assignment, but just
using gimple_assign_set_rhs1 is insufficient: the previous rhs was an
ADDR_EXPR, and that code remains afterwards.
Fixed with the following patch, tested (including Ada) on x86_64-linux. Ok?
