/* Test "ignore redundant include" facility. -H is used because cpp might confuse the issue by optimizing out #line markers. This test only passes if the headers is read twice. The disgusting regexp in the dg-error line, when stuck into dg.exp's compiler-output regexp, matches the correct -H output and only the correct -H output. It has to be all on one line because otherwise it will not be interpreted all in one unit. */ /* { dg-do preprocess } { dg-options "-H" } { dg-error "mi7a\.h\n\[^\n\]*mi7a\.h\n\[^\n\]*mi7b\.h\n\[^\n\]*mi7b\.h" "redundant include check" { target *-*-* } 0 } */ #include "mi7a.h" #include "mi7a.h" #include "mi7b.h" #include "mi7b.h"
