# The problem on Alpha at -O3 is that when dd is inlined, we have# division by a constant, which gets converted to multiplication# by a large constant, which gets turned into an induction variable.# The problem is that the multiplication was unsigned SImode, and the# induction variable is DImode, and we lose the truncation that# should have happened.## On tree-ssa branch, the loop problem is still extant, but the# gimple-level optimization makes it easy for the tree-rtl expanders# to see that the comparisons are always true, and so the loop code# is never exercized.# set torture_eval_before_execute {# # set compiler_conditional_xfail_data {# "division by a constant conflicts with strength reduction" \# "alpha*-*-*" \# { "-O3" } \# { "" }# }# }return 0
