Currently, the verification string anddiagnostic message are compared. If either is a substring of the other, thenno 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 parametersIt will also match these other error messages: candidate function function has different number of parameters number of parametersThis patch will change so that the verification string must be a substring ofthe diagnostic message before accepting. Also, all the failing tests from thischange have been corrected. Some stats from this cleanup:87 - removed extra spaces around verification strings70 - wording updates to diagnostics40 - 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 List of files: /llvm-project-15.0.7/clang/test/SemaCXX/complex-overload.cpp Thu, 15 Dec 2011 00:38:15 +0000 Richard Trieu <rtrieu@google.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/clang/test/SemaCXX/complex-overload.cpp#8fa1e7ee Add a new conversion rank to classify conversions between complex and scalartypes. Rank these conversions below other conversions. This allows overloadresolution when the only distinction is between a complex and scalar type. Italso brings the complex overload resolutin in line with GCC's.llvm-svn: 97128 List of files: /llvm-project-15.0.7/clang/test/SemaCXX/complex-overload.cpp Thu, 25 Feb 2010 07:20:54 +0000 Chandler Carruth <chandlerc@gmail.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/clang/test/SemaCXX/complex-overload.cpp#8fbe78f6 Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'. - This is designed to make it obvious that %clang_cc1 is a "test variable" which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it can be useful to redefine what gets run as 'clang -cc1' (for example, to set a default target).llvm-svn: 91446 List of files: /llvm-project-15.0.7/clang/test/SemaCXX/complex-overload.cpp Tue, 15 Dec 2009 20:14:24 +0000 Daniel Dunbar <daniel@zuster.org> http://172.16.0.5:8080/history/llvm-project-15.0.7/clang/test/SemaCXX/complex-overload.cpp#a45cf5b6 Rename clang to clang-cc.Tests and drivers updated, still need to shuffle dirs.llvm-svn: 67602 List of files: /llvm-project-15.0.7/clang/test/SemaCXX/complex-overload.cpp Tue, 24 Mar 2009 02:24:46 +0000 Daniel Dunbar <daniel@zuster.org> http://172.16.0.5:8080/history/llvm-project-15.0.7/clang/test/SemaCXX/complex-overload.cpp#6752502b Expand the definition of a complex promotion to include complex ->complex conversions where the conversion between the real types is anintegral promotion. This is how G++ handles complex promotions for itscomplex integer extension.llvm-svn: 64344 List of files: /llvm-project-15.0.7/clang/test/SemaCXX/complex-overload.cpp Thu, 12 Feb 2009 00:26:06 +0000 Douglas Gregor <dgregor@apple.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/clang/test/SemaCXX/complex-overload.cpp#78ca74d8 Introduce _Complex conversions into the function overloadingsystem. Since C99 doesn't have overloading and C++ doesn't have_Complex, there is no specification for this. Here's what I thinkmakes sense.Complex conversions come in several flavors: - Complex promotions: a complex -> complex conversion where the underlying real-type conversion is a floating-point promotion. GCC seems to call this a promotion, EDG does something else. This is given "promotion" rank for determining the best viable function. - Complex conversions: a complex -> complex conversion that is not a complex promotion. This is given "conversion" rank for determining the best viable function. - Complex-real conversions: a real -> complex or complex -> real conversion. This is given "conversion" rank for determining the best viable function.These rules are the same for C99 (when using the "overloadable"attribute) and C++. However, there is one difference in the handlingof floating-point promotions: in C99, float -> long double and double-> long double are considered promotions (so we give them "promotion" rank), while C++ considers these conversions ("conversion" rank).llvm-svn: 64343 List of files: /llvm-project-15.0.7/clang/test/SemaCXX/complex-overload.cpp Thu, 12 Feb 2009 00:15:05 +0000 Douglas Gregor <dgregor@apple.com>
