* Revert "intmax_t is long long on Darwin, not long."Jordan Rose2013-02-201-1/+1
| | | | | | | | | 'long' and 'long long' are different for the purposes of mangling. This caused <rdar://problem/13254874>. This reverts commit c2f994d31ec85e9af811af38eb1b28709aef0b2c. llvm-svn: 175681

* Tighten format string diagnostic and make it a bit clearer (and a bit closer ↵Ted Kremenek2012-01-201-4/+4
| | | | | | to GCC's). llvm-svn: 148579
* Modify how the -verify flag works. Currently, the verification string andRichard Trieu2011-12-151-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | diagnostic message are compared. If either is a substring of the other, then no error is given. This gives rise to an unexpected case: // expect-error{{candidate function has different number of parameters}} will match the following error messages from Clang: candidate function has different number of parameters (expected 1 but has 2) candidate function has different number of parameters It will also match these other error messages: candidate function function has different number of parameters number of parameters This patch will change so that the verification string must be a substring of the diagnostic message before accepting. Also, all the failing tests from this change have been corrected. Some stats from this cleanup: 87 - removed extra spaces around verification strings 70 - wording updates to diagnostics 40 - extra leading or trailing characters (typos, unmatched parens or quotes) 35 - diagnostic level was included (error:, warning:, or note:) 18 - flag name put in the warning (-Wprotocol) llvm-svn: 146619
* Make printf warnings refer to intmax_t et al. by nameHans Wennborg2011-12-071-4/+4
| | | | | | | | | | | | in addition to underlying type. For example, the warning for printf("%zu", 42.0); changes from "conversion specifies type 'unsigned long'" to "conversion specifies type 'size_t' (aka 'unsigned long')" (This is a second attempt after r145697, which got reverted.) llvm-svn: 146032
* Teach format string analysis that "%zu" means size_t.Hans Wennborg2011-10-271-0/+15
The code had it backwards, thinking size_t was signed, and using that for "%zd". Also let the analysis get the types for (u)intmax_t while we are at it. llvm-svn: 143099
