| | | | | | | | | | | | | modules. This leaves us without an explicit syntax for importing modules in C/C++, because such a syntax needs to be discussed first. In Objective-C/Objective-C++, the @import syntax is used to import modules. Note that, under -fmodules, C/C++ programs can import modules via the #include mechanism when a module map is in place for that header. This allows us to work with modules in C/C++ without committing to a syntax. llvm-svn: 147467

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

* Modules hide macro definitions by default, so that silly things likeDouglas Gregor2011-09-011-0/+33
include guards don't show up as macro definitions in every translation unit that imports a module. Macro definitions can, however, be exported with the intentionally-ugly #__export_macro__ directive. Implement this feature by not even bothering to serialize non-exported macros to a module, because clients of that module need not (should not) know that these macros even exist. llvm-svn: 138943
