2009-04-07Various fixes to symbols used for Obj-C x86_64 metadata.Daniel Dunbar
- Changed method names to match gcc (categories names still aren't mangled in). - Expose correct name for class and metadata symbols (although -fvisibility=hidden isn't yet correct). - Remove several things from llvm.used that didn't need to be there (I suspect this can still be trimmed). - Don't use asm-prefix extension for _objc_empty_{cache,vtable} (not needed). - Hide EH type class info with -fvisibility=hidden - Change setGlobal[Option]Visibility to not change the visibility of functions with internal linkage. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68510 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-07Add test case.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68505 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-07Remove hack from LiveVariables analysis where variables whose address are takenTed Kremenek
are considered 'live'. This hack isn't needed anymore because we have a separation in the path-sensitive analyzer between variable names and bindings; the analyzer can continue to reason about the storage of a variable after its name is no longer directly referenced. Now the live variables analysis literally means "is this name live". Along this line, update the dead stores checker to explicitly look for variables whose values have escaped. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68504 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-07define __va_copy unconditionally, but va_copy only in c99 or non-ansi mode.Chris Lattner
Fixes rdar://6759546, some code that actually used __va_copy because they thought it was "more portable". git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68503 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-07The __weak and __strong defines are common to all darwin targetsChris Lattner
and are even set in C mode. As such, move them to Targets.cpp. __OBJC_GC__ is also darwin specific, but seems reasonable to always define it when in objc-gc mode. This fixes rdar://6761450 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68494 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-06Warn instead of error on duplicate protocol definitions.Fariborz Jahanian
Be kind to so many projects which are doing this (and be like gcc). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68474 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-06Rewrite control-flow diagnostic generation "extensive" algorithm using "edgeTed Kremenek
contexts". This allows us to use a stack of contexts to keep track of what control-flow pieces to include when exiting blocks like 'if', 'for', etc. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68473 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-06Make casting 'super' a deprecated warning (instead of a hard error).Steve Naroff
This will simplify clang adoption, and is probably better "etiquette" (since gcc has always accepted this idiom without warning). Once we are over the adoption hurdle, we can turn this into an error. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68468 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-06Daniel convinced me that accepting "const va_list" arguments to va_arg isChris Lattner
a really really bad idea. Now that we emit an error about the unpromoted type, users should be able to understand what is going on. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68447 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-04Driver: Handle properly calling dsymutil when source input isDaniel Dunbar
preceeded by a linker input flag. - <rdar://problem/6757236> clang should make a dSYM when going straight from source to binary - This still matches gcc, but the right way to solve this would be to detect the situation we care about (we are compiling from source and linking in one step), instead of looking at the suffix of the input file. The Tool doesn't quite have enough information to do this yet, however. - Also, find the suffix correctly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68417 91177308-0d34-0410-b5e6-96231b3b80d8
