dwarves-1.8-1.fc12 has been submitted as an update for Fedora 12. http://admin.fedoraproject.org/updates/dwarves-1.8-1.fc12 dwarves-1.8-1.fc12 has been pushed to the Fedora 12 stable repository. If problems still persist, please make note of it in this bug report. |
Description of problem: when I run pahole on F12 x86_64 I'm getting BRAIN FART ALERTs (and other issues). Version-Release number of selected component (if applicable): dwarves-1.7-5.x86_64 How reproducible: Always Steps to Reproduce: 1. run pahole against the swiss_cheese example 2. see "BRAIN FART ALERT! ..." Actual results: $ pahole swiss_cheese struct cheese { char name[17]; /* 0 17 */ short int age; /* 0 2 */ char type; /* 0 1 */ int calories; /* 0 4 */ short int price; /* 0 2 */ int barcode[4]; /* 0 16 */ /* size: 48, cachelines: 1, members: 6 */ /* padding: 32 */ /* last cacheline: 48 bytes */ /* BRAIN FART ALERT! 48 != 17 + 0(holes), diff = 31 */ }; Expected results: $ pahole swiss_cheese struct cheese { char name[17]; /* 0 17 */ /* XXX 1 byte hole, try to pack */ short int age; /* 18 2 */ char type; /* 20 1 */ /* XXX 3 bytes hole, try to pack */ int calories; /* 24 4 */ short int price; /* 28 2 */ /* XXX 2 bytes hole, try to pack */ int barcode[4]; /* 32 16 */ /* size: 48, cachelines: 1, members: 6 */ /* sum members: 42, holes: 3, sum holes: 6 */ /* last cacheline: 48 bytes */ }; Additional info: I haven't attached the "swiss_cheese" example (which I got from acme's OLS 2007 "7 dwarves" paper) because acme has already given me a patch to test. I verified that the patch (attached) fixes pahole on F12.
