However I am not sure if that's possible, so XFAIL'd for arm-none-eabi. With cortex-m7 I am still seeing the XFAIL: XFAIL: gcc.dg/uninit-pred-8_a.c bogus warning (test for bogus messages, line 21) PASS: gcc.dg/uninit-pred-8_a.c bogus warning (test for bogus messages, line 24) PASS: gcc.dg/uninit-pred-8_a.c bogus warning (test for bogus messages, line 27) PASS: gcc.dg/uninit-pred-8_a.c warning (test for warnings, line 43) PASS: gcc.dg/uninit-pred-8_a.c (test for excess errors) Thanks, Prathamesh
