2012-05-26In response to some discussions on IRC, tweak the wording of the newRichard Smith
-Wsometimes-uninitialized diagnostics to make it clearer that the cause of the issue may be a condition which must always evaluate to true or false, rather than an uninitialized variable. To emphasize this, add a new note with a fixit which removes the impossible condition or replaces it with a constant. Also, downgrade the diagnostic from -Wsometimes-uninitialized to -Wconditional-uninitialized when it applies to a range-based for loop, since the condition is not written explicitly in the code in that case. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@157511 91177308-0d34-0410-b5e6-96231b3b80d8

-Wsometimes-uninitialized. This detects cases where an explicitly-written branch inevitably leads to an uninitialized variable use (so either the branch is dead code or there is an uninitialized use bug).

2012-05-24fix Bug 12924Seth Cantrell
http://llvm.org/bugs/show_bug.cgi?id=12924 This issue was that the source location was pointing to a non-printable character and so CaretEnd was pointing one _column_ past the caret but not one _character_ past the caret. So the conversion between column and byte locations wasn't working (because the conversion is only valid from the first column or byte of a character). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@157372 91177308-0d34-0410-b5e6-96231b3b80d8
2012-05-24DR1152 / PR12931 / PR6177: A candidate function which requires binding a constRichard Smith
volatile reference to a temporary is not viable. My interpretation is that DR1152 was a bugfix, not a rule change for C++11, so this is not conditional on the language mode. This matches g++'s behavior. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@157370 91177308-0d34-0410-b5e6-96231b3b80d8

Conceptually, this is part of -Wunused-value, but I added a separate flag -Wunused-volatile-lvalue so it doesn't get turned off by accident with -Wno-unused-value. I also made a few minor improvements to existing unused value warnings in the process. <rdar://problem/11516811>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@157362 91177308-0d34-0410-b5e6-96231b3b80d8

start with a cv-qualifier. DeclaratorDecl::getTypeSpecStartLoc() does not produce the location of the first type-specifier (the cv-qualifier) in this case, because we don't track source locations for cv-qualifiers.
