Bug ID: 112976
Summary: expand_gimple_stmt_1 vs
gimple_assign_nontemporal_move_p vs SSA_NAME on lhs
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Keywords: internal-improvement
Severity: normal
Priority: P3
Component: middle-end
Assignee: unassigned at gcc dot gnu.org
Reporter: pinskia at gcc dot gnu.org
Target Milestone: ---
As far as I can tell if TREE_CODE (lhs) == SSA_NAME then
gimple_assign_nontemporal_move_p should always be false as it is never a store.
So all of the code for nontemporal in the else case of `TREE_CODE (lhs) !=
SSA_NAME` if in cfgexpand.cc is dead.
This has been there since r0-95521-g28ed065ef9f345 which added expand from
tuples directly.
We most likely should also have gimple_assign_set_nontemporal_move assert that
the gimple assign's lhs is not a SSA_NAME.
