2012-02-16Format string analysis: give 'q' its own enumerator.Hans Wennborg
This is in preparation for being able to warn about 'q' and other non-standard format string features. It also allows us to print its name correctly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150697 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-15Make -Wformat fix-its preserve original conversion specifiers.Hans Wennborg
This commit makes PrintfSpecifier::fixType() and ScanfSpecifier::fixType() only fix a conversion specification enough that Clang wouldn't warn about it, as opposed to always changing it to use the "canonical" conversion specifier. (PR11975) This preserves the user's choice of conversion specifier in cases like: printf("%a", (long double)1); where we previously suggested "%Lf", we now suggest "%La" printf("%x", (long)1); where we previously suggested "%ld", we now suggest "%lx". git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150578 91177308-0d34-0410-b5e6-96231b3b80d8
