------- Comment #6 from rguenth at gcc dot gnu dot org 2010-08-27 12:16 ------- Without -fbounds-check we have around 650 million calls to iv_ca_get_num_inv_exprs ... called from iv_ca_recount_cost. With -fbounds-check this balloons to nearly 5 billion calls to that function.
David - this sounds like your changes, can you have a look to possibly reduce this number of calls? -- rguenth at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |xinliangli at gmail dot com http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45422
