You want the XFAIL to apply to compilation, not execution, and only for
"-O3 -g", not for all uses of -O3. This one works (surprisingly, because
as Andrew said it's usually not possible to XFAIL an ICE).
set torture_eval_before_compile {
set compiler_conditional_xfail_data {
"PR 28834" { "*-*-*" } { "-O3 -g" } { "" }
}
}
return 0
