This test only passes if the headers is read 5 twice. 6 7 The disgusting regexp in the dg-error line, when stuck into 8 dg.exp's compiler-output regexp, matches the correct -H output and 9 only the correct -H output. It has to be all on one line because 10 otherwise it will not be interpreted all in one unit. */ 11 12/* { dg-do preprocess } 13 { dg-options "-H" } 14 { dg-message "mi7a\.h\n\[^\n\]*mi7a\.h\n\[^\n\]*mi7b\.h\n\[^\n\]*mi7b\.h" "redundant include check" { target *-*-* } 0 } */ 15 16#include "mi7a.h" 17#include "mi7a.h" 18#include "mi7b.h" 19#include "mi7b.h" 20
