2010-04-10Driver/Darwin/x86: When linking, incorporate -L paths based on the path whereDaniel Dunbar
Clang is installed. This is designed to match gcc, and is important when installed in a non-standard location. - This is gross, but no worse than ever. It will die when we finally move to the compiler-rt based toolchain, any day now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100915 91177308-0d34-0410-b5e6-96231b3b80d8

mangling an unknown expression kind. Also conveniently tells the user what kind of expression they should add to the mangler! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100907 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-09Only complain about explicit instantiations following explicitDouglas Gregor
specializations when the explicit instantiation was... explicitly written, i.e., not the product of an explicit instantiation of an enclosing class. Fixes this spurious warning when Clang builds LLVM: /Volumes/Data/dgregor/Projects/llvm/lib/CodeGen/MachineDominators.cpp:22:1: warning: explicit instantiation of 'addRoot' that occurs after an explicit specialization will be ignored (C++0x extension) [-pedantic] git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100900 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-09Remove fixit for string literal comparison. Telling the user to use ↵Ted Kremenek
'strcmp' is bad, and we don't have enough information to tell them how to use 'strncmp'. Instead, change the diagnostic to indicate they should use 'strncmp'. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100890 91177308-0d34-0410-b5e6-96231b3b80d8

fails to find a type. There are no cases where it's valid for this to produce an error. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100878 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-09Remove all "used" static functions *after* we have performed all ofDouglas Gregor
the implicit template instantiations we need to perform. Otherwise, we end up erroneously diagnosing static functions as used if they were only used within an implicit template instantiation. Fixes a bunch of spurious failures when building Clang with Clang. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100872 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-09On Windows, disable the modification-time check for files used inDouglas Gregor
precompiled headers and/or when reading the contents of the file into memory. These checks seem to be causing spurious regression-test failures on Windows. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100866 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-09Improve diagnostics when we fail to convert from a source type to aDouglas Gregor
destination type for initialization, assignment, parameter-passing, etc. The main issue fixed here is that we used rather confusing wording for diagnostics such as t.c:2:9: warning: initializing 'char const [2]' discards qualifiers, expected 'char *' [-pedantic] char *name = __func__; ^ ~~~~~~~~ We're not initializing a 'char const [2]', we're initializing a 'char *' with an expression of type 'char const [2]'. Similar problems existed for other diagnostics in this area, so I've normalized them all with more precise descriptive text to say what we're initializing/converting/assigning/etc. from and to. The warning for the code above is now: t.c:2:9: warning: initializing 'char *' from an expression of type 'char const [2]' discards qualifiers [-pedantic] char *name = __func__; ^ ~~~~~~~~ Fixes <rdar://problem/7447179>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100832 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-08For 'open' check in UnixAPIChecker, hard code value of 'O_CREAT' on Darwin.Ted Kremenek
This is still not an ideal solution, but should disable the check for other targets where the value of O_CREAT is different. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100818 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-08Downgrade the "declaration does not declare anything" error to aDouglas Gregor
warning. It's not harmful to have such pointless declarations, and GCC does not diagnose this issue consistently. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100814 91177308-0d34-0410-b5e6-96231b3b80d8

variable declarations. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100809 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-08Add static analyzer check for calls to 'pthread_once()' where the ↵Ted Kremenek
control-flow has automatic storage. This matches the corresponding check for 'dispatch_once()'. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100803 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-08Remove micro-optimization for not issueing CFG-based warnings for 'static ↵Ted Kremenek
inline' functions unless they are used. I discussed this with Daniel Dunbar, and we agreed that this provides an inconsistent warnings experience for the user and that there were genuine cases where we wouldn't want to do this optimization. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100800 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-08Introduce an egregious hack to work around a bug in libstdc++ 4.2.x'sDouglas Gregor
<tr1/hashtable> header, where a friend class template std::tr1::__detail::_Map_base is declared with the wrong template parameters. GCC doesn't catch the problem, so Clang does a little back-flip to avoid diagnosing just this one instance of the problem. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100790 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-08Eliminate excessive PCH deserialization caused by the search forDouglas Gregor
__cxxabiv1::__fundamental_type_info in every translation unit. Previously, we would perform name lookup for __cxxabiv1::__fundamental_type_info at the end of IRGen for a each translation unit, to determine whether it was present. If so, we we produce type information for all of the fundamental types. However, this name lookup causes PCH deserialization of a significant part of the translation unit, which has a woeful impact on performance. With this change, we now look at each record type after we've generated its vtable to see if it is __cxxabiv1::__fundamental_type_info. If so, we generate type info for all of the fundamental types. This works because __cxxabiv1::__fundamental_type_info should always have a key function (typically the virtual destructor), that will be defined once in the support library. The fundamental type information will end up there. Fixes <rdar://problem/7840011>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100772 91177308-0d34-0410-b5e6-96231b3b80d8
