2008-11-22Change the Lexer::Diag method to not magically silence warnings,Chris Lattner
force the caller to check instead. This eliminates the need (and the risk!) of weird null DiagnosticBuilder's floating around. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59856 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-22Split the DiagnosticInfo class into two disjoint classes:Chris Lattner
one for building up the diagnostic that is in flight (DiagnosticBuilder) and one for pulling structured information out of the diagnostic when formatting and presenting it.

2008-11-21Add the concept of "modifiers" to the clang diagnostic format Chris Lattner
strings. This allows us to have considerable flexibility in how these things are displayed and provides extra information that allows us to merge away diagnostics that are very similar. Diagnostic modifiers are a string of characters with the regex [-a-z]+ that occur between the % and digit. They may optionally have an argument that can parameterize them. For now, I've added two example modifiers. One is a very useful tool that allows you to factor commonality across diagnostics that need single words or phrases combined. Basically you can use %select{a|b|c}4 with with an integer argument that selects either a/b/c based on an integer value in the range [0..3). The second modifier is also an integer modifier, aimed to help English diagnostics handle plurality. "%s3" prints to 's' if integer argument #3 is not 1, otherwise it prints to nothing. I'm fully aware that 's' is an English concept and doesn't apply to all situations (mouse vs mice). However, this is very useful and we can add other crazy modifiers once we add support for polish! ;-) I converted a couple C++ diagnostics over to use this as an example, I'd appreciate it if others could merge the other likely candiates. If you have other modifiers that you want, lets talk on cfe-dev. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59803 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-21move the diagnostic location and ID out of DiagnosticInfo and store it inChris Lattner
the Diagnostic class. Since we can already only have one diagnostic in flight at a time, this shrinks DiagnosticInfo. This reduces DiagnosticInfo to being basically a rather crazy smart pointer to a DiagnosticInfo :) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59798 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-21move diagnostic insertion methods to be free methods instead ofChris Lattner
in the DiagnosticInfo class. This requires marking them as taking a const DiagnosticInfo, which is bogus (they logically mutate DI), but works with the C++ type system. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59797 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-21Change -verify mode to find the "expected-error" and "expected-warning" stringsChris Lattner
with a raw lexer instead of a PP lexer. This means that -verify doesn't scan #include'd headers for expected-error/warning strings, and it also means that it doesn't ignore them in #if 0. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59774 91177308-0d34-0410-b5e6-96231b3b80d8
