2010-10-14template-ids are looked up differently in friend declarations.John McCall
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116529 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-14When performing typo correction, look through the set of knownDouglas Gregor
identifiers to determine good typo-correction candidates. Once we've identified those candidates, we perform name lookup on each of them and the consider the results. This optimization makes typo correction > 2x faster on a benchmark example using a single typo (NSstring) in a tiny file that includes Cocoa.h from a precompiled header, since we are deserializing far less information now during typo correction. There is a semantic change here, which is interesting. The presence of a similarly-named entity that is not visible can now affect typo correction. This is both good (you won't get weird corrections if the thing you wanted isn't in scope) and bad (you won't get good corrections if there is a similarly-named-but-completely-unrelated thing). Time will tell whether it was a good choice or not. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116528 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-14Fix compiler error that clang didn't report (probably same problem as ↵Argyrios Kyrtzidis
rdar://8552377). It's more stress-free without access checking though.. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116521 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116519 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-14r116509 fixed the Win32 XFAIL.Francois Pichet
The failing was due to this: 1. preamble.c contains CR+LF new lines 2. write() is called with a buffer containing the original (CR+LF) to output the result on the console. 3. In text mode(the default), write() convert LF to CR+LF even if LF is preceded by CR, hence we have CR+CR+LF which filecheck interprets as 2 lines. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116513 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-14Tweak the typo-correction implementation to determine correctionsDouglas Gregor
solely based on the names it sees, rather than actual declarations it gets. In essence, we determine the set of names that are "close enough" to the typo'd name. Then, we perform name lookup for each of those names, filtering out those that aren't actually visible, and typo-correct from the remaining results. Overall, there isn't much of a change in the behavior of typo correction here. The only test-suite change comes from the fact that we make good on our promise to require that the user type 3 characters for each 1 character corrected. The real intent behind this change is to set the stage for an optimization to typo correction (so that we don't need to deserialize all declarations in a translation unit) and future work in finding missing qualification ("'vector' isn't in scope; did you mean 'std::vector'?). Plus, the code is cleaner this way. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116511 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-14Store in PCH the key function of C++ class to avoid deserializing the ↵Argyrios Kyrtzidis
complete declaration context in order to compute it. Progress for rdar://7260160. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116508 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-14Allow deserialization of just the fields of a record, when we want to ↵Argyrios Kyrtzidis
iterate over them, instead of deserializing the complete declaration context of the record. Iterating over the fields of a record is very common (e.g to determine the layout), unfortunately we needlessly deserialize every declaration that the declaration context of the record contains; this can be bad for large C++ classes that contain a lot of methods. Fix this by allow deserialization of just the fields when we want to iterate over them. Progress for rdar://7260160. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116507 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-14Introduce command line option -error-on-deserialized-decl that is ↵Argyrios Kyrtzidis
accompanied by a name and emits an error if a declaration with this name is deserialized from PCH. This is for testing, to make sure that we don't deserialize stuff needlessly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116505 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-14Don't add the injected class name to the redeclarations chain; the chain ↵Argyrios Kyrtzidis
should contain actual redeclarations, not implicits. As a bonus, now we don't deserialize it unless we need it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116504 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-13Introduce a bit into Type that keeps track of whether there are anyDouglas Gregor
unnamed or local types within that type. This bit is cached along with the linkage of a type, so that it can be recomputed (e.g., when we see that a typedef has given a name to an anonymous declaration). Use this bit when checking C++03 [temp.arg.type]p2, so that we don't walk template argument types repeatedly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116413 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-13Teach the warning about unnamed/local types in template arguments toDouglas Gregor
actually walk the template argument type to find any unnamed/local types within it. Fixes PR6784. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116382 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-12Introduce support for emitting diagnostics (warnings + their notes)Douglas Gregor
that are suppressed during template argument deduction. This change queues diagnostics computed during template argument deduction. Then, if the resulting function template specialization or partial specialization is chosen by overload resolution or partial ordering (respectively), we will emit the queued diagnostics at that point. This addresses most of PR6784. However, the check for unnamed/local template arguments (which existed before this change) is still only skin-deep, and needs to be extended to look deeper into types. It must be improved to finish PR6784. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116373 91177308-0d34-0410-b5e6-96231b3b80d8
