2009-04-07Driver: Fix forwarding of -{std,ansi,trigraphs} when there areDaniel Dunbar
multiple instances of an option. Also, removed direct -ansi support from clang-cc. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68558 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-07Driver: Forward remaining -f options to clang manually.Daniel Dunbar
- Groups are really just intended to hold inherent structure of the options, not be abused for individual tool argument translation. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68554 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-07Driver: Only forward last instance of -mmacosx-version-min= andDaniel Dunbar
-isysroot to clang. - Don't forward arbitrary -i* options to clang, just the ones we know about. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68553 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-07Now that we have __weak defined as attribute in all modes,Fariborz Jahanian
we must not issue gc-specific errors in non-gc mode. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68551 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-07Driver: Manually translate a number of -f with no- variants options toDaniel Dunbar
clang. - We will eventually want some more driver infrastructre for this probably. - For now, the clang-cc interface stays relatively the same, but we don't accept multiple instances anymore, or the [no-] variants directly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68550 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-07Driver: Add 'q' flag for options which shouldn't be reported as unused.Daniel Dunbar
- <rdar://problem/6756295> warning about '-dynamic' argument unused during compilation seems incorrect git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68535 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-07Fixes method name lookup when method appears inFariborz Jahanian
the base implementations (and not in current implementation). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68527 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-07Driver: Fix a parsing bug where some options were matchedDaniel Dunbar
incorrectly. I'm blanking on the smartest way to write this search, but we should just do the right thing when we move to TableGen. - <rdar://problem/6761194> [driver] -Wextra-tokens isn't parsed correctly git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68525 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-07Move the internal DeclContext data structures into a separate header. Douglas Gregor
Simplify the addition of a case statement to a switch. Fix -print-stats for attribute-qualified types. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68522 91177308-0d34-0410-b5e6-96231b3b80d8

in C mode. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68520 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-07Tweak Sema::ActOnInstanceMessage() to look for a class method when dealing ↵Steve Naroff
with qualified id's. This change is motivated by our desire to not support the "Class<foo>" idiom. Note that the change makes perfect sense (since all ObjC classes are also id/instances). This allow us to document a simple migration path...change "Class <foo>" to "id <foo>". This effects: - <rdar://problem/6761939> TASK: File source change radars for "qualified Class" errors - <rdar://problem/6761864> Protocol qualified Class is unsupported git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68517 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-07Change the type of ObjC @ string constants (from NSConstantString->NSString).Steve Naroff
This fixes <rdar://problem/6757102> clang type for @"xxx" is "NSConstantString *" (GCC type is "NSString *"). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68514 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-07Handle use side of __objc_exception__ attribute; when using anDaniel Dunbar
exception with this attribute we don't need to emit a weak definition for the exception type information. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68513 91177308-0d34-0410-b5e6-96231b3b80d8
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
2009-04-07Remove 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
2009-04-07Remove GetLeakNode. This isn't the right approach.Ted Kremenek

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
2009-04-07Remove hack support for @try...@finally in source-level CFGs. The current hackTed Kremenek
had too many false positives in the analyzer. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68492 91177308-0d34-0410-b5e6-96231b3b80d8

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
