2012-07-06Restrict the set of declaration kinds for which we allow trailing comments.Dmitri Gribenko
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159878 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-06Implement -Wpedantic and --no-pedantic to complement -Weverything.Ted Kremenek
This patch introduces some magic in tablegen to create a "Pedantic" diagnostic group which automagically includes all warnings that are extensions. This allows a user to suppress specific warnings traditionally under -pedantic used an ordinary warning flag. This also allows users to use #pragma to silence specific -pedantic warnings, or promote them to errors, within blocks of text (just like any other warning). -Wpedantic is NOT an alias for -pedantic. Instead, it provides another way to (a) activate -pedantic warnings and (b) disable them. Where they differ is that -pedantic changes the behavior of the preprocessor slightly, whereas -Wpedantic does not (it just turns on the warnings). The magic in the tablegen diagnostic emitter has to do with computing the minimal set of diagnostic groups and diagnostics that should go into -Wpedantic, as those diagnostics that already members of groups that themselves are (transitively) members of -Wpedantic do not need to be included in the Pedantic group directly. I went back and forth on whether or not to magically generate this group, and the invariant was that we always wanted extension warnings to be included in -Wpedantic "some how", but the bookkeeping would be very onerous to manage by hand. -no-pedantic (and --no-pedantic) is included for completeness, and matches many of the same kind of flags the compiler already supports. It does what it says: cancels out -pedantic. One discrepancy is that if one specifies --no-pedantic and -Weverything or -Wpedantic the pedantic warnings are still enabled (essentially the -W flags win). We can debate the correct behavior here. Along the way, this patch nukes some code in TextDiagnosticPrinter.cpp and CXStoredDiagnostic.cpp that determine whether to include the "-pedantic" flag in the warning output. This is no longer needed, as all extensions now have a -W flag. This patch also significantly reduces the number of warnings not under flags from 229 to 158 (all extension warnings). That's a 31% reduction. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159875 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-06Constify the argument to SourceLocation::getFromPtrEncoding.Jordan Rose
This allows SourceLocations to be stored in generic "data" fields that are typed as "const void *" and are also used to point to const objects. Really we should probably be returning a const pointer from getPtrEncoding as well, but in some places we want to store SourceLocations in the same generic "data" field as proper pointers to /mutable/ objects. Oh well. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159868 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-06[analyzer] Be careful about LazyCompoundVals, which may be for the first field.Jordan Rose
We use LazyCompoundVals to avoid copying the contents of structs and arrays around in the store, and when we need to pass a struct around that already has a LazyCompoundVal we just use the original one. However, it's possible that the first field of a struct may have a LazyCompoundVal of its own, and we currently can't distinguish a LazyCompoundVal for the first element of a struct from a LazyCompoundVal for the entire struct. In this case we should just drop the optimization and make a new LazyCompoundVal that encompasses the old one.

2012-07-06Add -ffp-contract = { fast | on | off } command line option support.Lang Hames
This flag sets the 'fp-contract' mode, which controls the formation of fused floating point operations. Available modes are: - Fast: Form fused operations anywhere. - On: Form fused operations where allowed by FP_CONTRACT. This is the default mode. - Off: Don't form fused operations (in future this may be relaxed to forming fused operations where it can be proved that the result won't be affected). Currently clang doesn't support the FP_CONTRACT pragma, so the 'On' and 'Off' modes are equivalent. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159794 91177308-0d34-0410-b5e6-96231b3b80d8
