tree-optimization/120043 - bogus conditional store elimination
The following fixes conditional store elimination to properly
check for conditional stores to readonly memory which we can
obviously not store to unconditionally. The tree_could_trap_p
predicate used is only considering rvalues and the chosen
approach mimics that of loop store motion.
PR tree-optimization/120043
* tree-ssa-phiopt.cc (cond_store_replacement): Check
whether the store is to readonly memory.
* gcc.dg/torture/pr120043.c: New testcase.
