/* Test "ignore redundant include" facility. We must test with C and C++ comments, and null directives, outside the guard conditional; also, we test guarding with #ifndef and #if !defined. -H is used because cpp might confuse the issue by optimizing out #line markers. This test only passes if each of the headers is read exactly once. 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 compile } { dg-options "-H" } { dg-message "mi1c\.h\n\[^\n\]*mi1cc\.h\n\[^\n\]*mi1nd\.h\n\[^\n\]*mi1ndp\.h\n\[^\n\]*mi1x\.h" "redundant include check" { target *-*-* } 0 } */ #include "mi1c.h" #include "mi1c.h" #include "mi1c.h" #include "mi1cc.h" #include "mi1cc.h" #include "mi1nd.h" #include "mi1nd.h" #include "mi1ndp.h" #include "mi1ndp.h" #define MIX_H #include "mi1x.h" #include "mi1x.h" int main (void) { return a + b + c + d; }
