2013-01-25Clarify comment: "diagnose" is better than "warn" when emitting an error.Jordan Rose
Thanks, Dmitri. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173400 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-25Clean up: since we have FunctionDecl::IsInline, make it store the right valueRichard Smith
for template instantiations, and use it to simplify the implementation of FunctionDecl::isInlined(). This incidentally changes the result of isInlined on a declared-but-not-defined non-inline member function from true to false. This is sort of a bug fix, but currently isInlined is only called on function definitions, so it has no visible effects. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173397 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-24[analyzer] Add "-analyzer-config mode=[deep|shallow] ".Anna Zaks
The idea is to introduce a higher level "user mode" option for different use scenarios. For example, if one wants to run the analyzer for a small project each time the code is built, they would use the "shallow" mode. The user mode option will influence the default settings for the lower-level analyzer options. For now, this just influences the ipa modes, but we plan to find more optimal settings for them. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173386 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-24[analyzer] Replace "-analyzer-ipa" with "-analyzer-config ipa".Anna Zaks
The idea is to eventually place all analyzer options under "analyzer-config". In addition, this lays the ground for introduction of a high-level analyzer mode option, which will influence the default setting for IPAMode. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173385 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-24Handle universal character names and Unicode characters outside of literals.Jordan Rose
This is a missing piece for C99 conformance. This patch handles UCNs by adding a '\\' case to LexTokenInternal and LexIdentifier -- if we see a backslash, we tentatively try to read in a UCN. If the UCN is not syntactically well-formed, we fall back to the old treatment: a backslash followed by an identifier beginning with 'u' (or 'U'). Because the spelling of an identifier with UCNs still has the UCN in it, we need to convert that to UTF-8 in Preprocessor::LookUpIdentifierInfo. Of course, valid code that does *not* use UCNs will see only a very minimal performance hit (checks after each identifier for non-ASCII characters, checks when converting raw_identifiers to identifiers that they do not contain UCNs, and checks when getting the spelling of an identifier that it does not contain a UCN). This patch also adds basic support for actual UTF-8 in the source. This is treated almost exactly the same as UCNs except that we consider stray Unicode characters to be mistakes and offer a fixit to remove them. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173369 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-24PR14922: when printing an attribute, use the real syntax of the attribute ↵Michael Han
(GNU, C++11, MS Declspec) instead of hardcoded GNU syntax. Introduce a spelling index to Attr class, which is an index into the attribute spelling list of an attribute defined in Attr.td. This index will determine the actual spelling used by an attribute, as it incorporates both the syntax and naming of the attribute. When constructing an attribute AST node, the spelling index is computed based on attribute kind, scope (if it's a C++11 attribute), and name, then passed to Attr that will use the index to print itself. Thanks to Richard Smith for the idea and review. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173358 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173303 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-23Implement the writer side of the global module index. Douglas Gregor
The global module index is a "global" index for all of the module files within a particular subdirectory in the module cache, which keeps track of all of the "interesting" identifiers and selectors known in each of the module files. One can perform a fast lookup in the index to determine which module files will have more information about entities with a particular name/selector. This information can help eliminate redundant lookups into module files (a serious performance problem) and help with creating auto-import/auto-include Fix-Its. The global module index is created or updated at the end of a translation unit that has triggered a (re)build of a module by scraping all of the .pcm files out of the module cache subdirectory, so it catches everything. As with module rebuilds, we use the file system's atomicity to synchronize. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173301 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-23Implement -Wvla correctlyDmitri Gribenko
GCC implements -Wvla as "warn on every VLA" (this is useful to find every VLA, for example, if they are forbidden by coding guidelines). Currently Clang implements -Wvla as "warn on VLA when it is an extension". The attached patch makes our behavior match GCC. The existing vla extwarn is moved under -Wvla-extension and is still included into -Wgnu. This fixes PR5953. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173286 91177308-0d34-0410-b5e6-96231b3b80d8

Before: bool aaaa = aaaaaaaaaaa( aaaaaaaaaaaaaaaaa); After: bool aaaa = aaaaaaaaaaa( aaaaaaaaaaaaaaaaa); The other indentation was a nice attempt but doesn't work in many cases. Not sure what the right long term solution is as the "After: " is still not nice. We either need to figure out what to do in the cases where it "doesn't work" or come up with a third solution, e.g. falling back to: bool aaaa = aaaaaaaaaaa( aaaaaaaaaaaaaaaaa); which should always work and nicely highlight the structure. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173268 91177308-0d34-0410-b5e6-96231b3b80d8
