1 /* Test "ignore redundant include" facility. | |
2 | |
3 We must test with C and C++ comments, and null directives, outside | |
4 the guard conditional; also, we test guarding with #ifndef and #if | |
5 !defined. -H is used because cpp might confuse the issue by | |
6 optimizing out #line markers. This test only passes if each of the | |
7 headers is read exactly once. | |
8 | |
9 The disgusting regexp in the dg-error line, when stuck into | |
10 dg.exp's compiler-output regexp, matches the correct -H output and | |
11 only the correct -H output. It has to be all on one line because | |
12 otherwise it will not be interpreted all in one unit. */ | |
