--- Comment #5 from Dominique d'Humieres <dominiq at lps dot ens.fr> 2011-10-30 11:34:15 UTC --- Created attachment 25666 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=25666 Further reduced test for induct.f90 The reduced test contains a single et of nested loops in mutual_ind_quad_cir_coil. Using the main program in http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34265#c34 (induct_red.f90), the execution time is 2.0s when induct_qc.f90 is compiled with -Ofast and 1.8s when it is compiled with -fprotect-parens -Ofast.
