2010-04-10Driver: Only add extra -L paths on darwin if they exist. Unfortunately, thisDaniel Dunbar
means it isn't really possible to write the test case for this code, but this is the kind of thing that really requires testing against the installed compiler anyway. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100935 91177308-0d34-0410-b5e6-96231b3b80d8

serve as a source of source locations for the can't-yet-mangle diagnostic. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100924 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-10Diagnose more cases of initializing distinct members of an anonymous unionJohn McCall
member. Use a better diagnostic for this case. Also fix a bug with nested anonymous structs/unions for -Wreorder; this last was PR6575. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100923 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-10Diagnose misordered initializers in constructor templates immediately instead ofJohn McCall
when they're instantiated. Merge the note into the -Wreorder warning; it doesn't really contribute much, and it was splitting a thought across diagnostics anyway. Don't crash in the parser when a constructor's initializers end in a comma and there's no body; the recovery here is still terrible, but anything's better than a crash. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100922 91177308-0d34-0410-b5e6-96231b3b80d8

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
2010-04-10Disable diag::err_file_modified on Win32 completely, until someone cares to fixDaniel Dunbar
it. PR6812. - This is another attempt at silencing annoying buildbot failures. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100914 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-09Provide an extremely unsatisfactory diagnostic (instead of crashing) whenJohn McCall
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
2010-04-09Provide manglings for bool and character literal expressions. These areJohn McCall
just integer-literal expressions with special case implementations in the AST. Fixes rdar://problem/7825453. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100905 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-09When upgrading an Objective-C class from a forward declaration to aDouglas Gregor
full-fledged @interface, be sure that the declaration has the right lexical context. <rdar://problem/7827709> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100903 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

2010-04-09Turn access control on by default in -cc1.John McCall
Remove -faccess-control from -cc1; add -fno-access-control. Make the driver pass -fno-access-control by default. Update a bunch of tests to be correct under access control. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100880 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
2010-04-09Improve diagnostics like "initializing <type> from an expression ofDouglas Gregor
type..." with "initializing <type> with an expression of type...", which reads better. Thanks to John for the improved wording. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100873 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

type isn't dependent. Fixes rdar://problem/7838962. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100871 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-09Don't warn about unused static functions if they are marked with Chris Lattner
attr constructor or destructor. Patch by Jean-Daniel Dupas! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100870 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

valid instantiations. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100836 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
2010-04-08Use '%clang_cc1' instead of '%clang' to make the warning output more ↵Ted Kremenek
consistent across platforms (for this test). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100827 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
