2010-06-20Adds analyzer support for idempotent and tautological binary operations such ↵Jordy Rose

2010-06-18introduce a new CharSourceRange class, and enhance the diagnostics routinesChris Lattner
to use them instead of SourceRange. CharSourceRange is just a SourceRange plus a bool that indicates whether the range has the end character resolved or whether the end location is the start of the end token. While most of the compiler wants to think of ranges that have ends that are the start of the end token, the printf diagnostic stuff wants to highlight ranges within tokens. This is transparent to the diagnostic stuff. To start taking advantage of the new capabilities, you can do something like this: Diag(..) << CharSourceRange::getCharRange(Begin,End) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@106338 91177308-0d34-0410-b5e6-96231b3b80d8

2010-06-17Bug 7377: Fixed several bad printf format string bugs.Tom Care
- Added warning for undefined behavior when using field specifier - Added warning for undefined behavior when using length modifier - Fixed warnings for invalid flags - Added warning for ignored flags - Added fixits for the above warnings - Fixed accuracy of detecting several undefined behavior conditions - Receive normal warnings in addition to security warnings when using %n - Fix bug where '+' flag would remain on unsigned conversion suggestions Summary of changes: - Added expanded tests - Added/expanded warnings - Added position info to OptionalAmounts for fixits - Extracted optional flags to a wrapper class with position info for fixits - Added several methods to validate a FormatSpecifier by component, each checking for undefined behavior - Fixed conversion specifier checking to conform to C99 standard - Added hooks to detect the invalid states in CheckPrintfHandler::HandleFormatSpecifier Note: warnings involving the ' ' (space) flag are temporarily disabled until whitespace highlighting no longer triggers assertions.

explicitly typed in the source, but we weren't recursing on it. One is new <type>, the other is <type>() (eg int()).
