 2010-08-03 16:48:42 +00:00
Daniel Dunbar 939c1211cc Driver: Don't forward any -g options to GCC, when using it to drive the 
assembler.
 - Fixes PR6218, hopefully.

Douglas Gregor 48c8cd3fd0 Reshuffle the PCH generator action and consumer, so that we can re-use 
it while generating precompiled preambles. No functionality change.

John McCall 5696d6d316 Emit weak vtables of non-template classes with hidden visibility.

Zhongxing Xu 42b8c30de6 Allow offsets to be negative. Out-of-bound cases are checked elsewhere. We 
shouldn't put restrictions in store manager.

llvm-svn: 110106
 2010-08-03 06:34:25 +00:00
Zhongxing Xu 83734e46ce Pull the region offset computation logic into a single method.

Bruno Cardoso Lopes 1f927ccaa2 Support x86 AVX 256-bit instructions built-ins. Right now support all of them, but 
as soon as we properly codegen the simple vector operations, remove the
unnecessary built-ins/intrinsics from clang and llvm. Also add tests for the new
built-ins

Tom Care 44081fbc6c Changed GRExprEngine to pass down a reference to itself when checkers are doing postanalysis. This allows the checker to gather information about the state of the engine when it has finished. 
- Exposed the worklist and BlockAborted flag in GRCoreEngine
- Changed postanalysis checkers to use the new infrastructure

Ted Kremenek 4a2b237967 Add -cc1 option '-unoptimized-cfg' to toggle using a CFG (for static analysis) that doesn't prune CFG edges. 
llvm-svn: 110087
 2010-08-03 00:09:51 +00:00
Ted Kremenek dc03bd0894 Add 'AnalysisContext::getUnoptimizedCFG()' to allow clients to get access to the original 
CFG without any edges pruned out because of trivially solvable conditions (e.g., 'if (0)').

llvm-svn: 110085
 2010-08-02 23:46:59 +00:00
John McCall 4a33fa95c0 Labels (and case statement) don't create independent scope parents for the 
purposes of the jump checker.  Also extend Ted's iteration fix to labels.

Fixes PR7789.

Sebastian Redl 75d8a32817 Simplify global method pool implementation in Sema. No functionality change. 
llvm-svn: 110078
 2010-08-02 23:18:59 +00:00
Ted Kremenek 04d50f5d13 Fix another case (this time in JumpScopeChecker) where walking deeply nested CaseStmts can blow out the stack. Fixes <rdar://problem/8125165>. 
llvm-svn: 110071
 2010-08-02 22:46:57 +00:00
Ted Kremenek 297e2e5bf6 Fix idempotent operations false positive caused by ivars not being invalidated in function 
calls when the enclosing object had retain/release state.  Fixes <rdar://problem/8261992>.

llvm-svn: 110068
 2010-08-02 21:59:12 +00:00
John McCall 8b0f4ff317 Further adjustments to -Wglobal-constructors; works for references and direct 
initializations now.

llvm-svn: 110063
 2010-08-02 21:13:48 +00:00
Douglas Gregor b1cf1ca19a Add Darwin dylib versioning support to libclang when build with CMake. 
llvm-svn: 110062
 2010-08-02 20:52:32 +00:00
Douglas Gregor d9a30af25b When using a precompiled preamble, save the diagnostics produced when 
creating the preamble and "replay" them when reusing the
preamble. Also, fix a thinko in the copying of the preamble when
building the precompiled preamble.

 2010-08-02 20:51:39 +00:00
Ted Kremenek 8a4a2b14e8 'Assumption &A' gets default initialized to 'Possible' if it doesn't exist; no need to two 
lookups in the hashtable.

llvm-svn: 110059
 2010-08-02 20:33:02 +00:00
Ted Kremenek 4b83f753a1 Add test case for <rdar://problem/8258814>.

 2010-08-02 20:33:00 +00:00
Sebastian Redl 78f5177d37 Query only the latest version of an identifier in the PCH chain. Make sure this version holds the entire declaration chain. This is a much saner solution than trying to merge the info from all elements, and makes redeclarations work properly. Expand the declarations test case to cover more compliated cases. 
llvm-svn: 110052
 2010-08-02 18:30:12 +00:00
Sebastian Redl 9d8854ec60 Remove mutable data on TagType and InjectedClassNameType, by instead walking the declaration chain in search of a definition. This is necessary for a sane chained PCH implementation. No observable performance change on Carbon.h syntax-only, and bootstraps cleanly.

Fariborz Jahanian 9c6a39e862 Compute width/align of objc builtin types (id, etc) 
for radar 8258797.

llvm-svn: 110047
 2010-08-02 18:03:20 +00:00
Daniel Dunbar 1b8842d981 Update UsersManual, we support '#pragma align' now. 
llvm-svn: 110040

Daniel Dunbar 2be96746b4 Frontend: Change PluginASTAction::ParseArgs to take a CompilerInstance object 
for use in reporting diagnostics.
 - We don't want to use the Action's own CompilerInstance, because that is only
   initialized during file processing and I like that invariant.

Also, if ParseArgs returns false then abandon execution.

Also, remove unused PluginASTAction::PrintHelp virtual method.

Argyrios Kyrtzidis cd948c1df5 You actually have to include a header in order to use a symbol, it's so 90s..

Argyrios Kyrtzidis 2d68810caf Read/write in PCH Sema's StdNamespace and StdBadAlloc and use a LazyDeclPtr for them that will deserialize them when needed.

 2010-08-02 07:14:54 +00:00
Argyrios Kyrtzidis 4f8e17379d Rename getStdNamespace -> getOrCreateStdNamespace, to better reflect its functionality. 
No functionality change.

Daniel Dunbar 71c723da29 Driver/Darwin: Change where Darwin computes the host version, to normalize tool 
chain construction.

llvm-svn: 110028
 2010-08-02 05:44:07 +00:00
Daniel Dunbar a73a9845e2 Driver: Have -ccc-host-triple simply override the default in the driver, for 
now.

llvm-svn: 110027
 2010-08-02 05:44:04 +00:00
Daniel Dunbar 3ae26dfc91 Driver/Darwin: Inline some constants. 
llvm-svn: 110026
 2010-08-02 05:44:01 +00:00
Daniel Dunbar a18a487633 Driver/FreeBSD: Change how FreeBSD derives the Lib32 variable, to normalize tool 
chain construction.

llvm-svn: 110025
 2010-08-02 05:43:59 +00:00
Daniel Dunbar cc7df6cc7b Driver: Move HostInfo::lookupTypeForExtension to ToolChain::LookupTypeForExtension. 
llvm-svn: 110024
 2010-08-02 05:43:56 +00:00
Daniel Dunbar a36c2b3a62 Driver: Give Build{Universal,}Actions access to the default host tool chain. I 
avoided this originally to enforce that the driver actions aren't toolchain
dependent, but it isn't worth the cumbersone additional hostinfo split.

llvm-svn: 110023
 2010-08-02 05:43:51 +00:00
Zhongxing Xu fd91d27630 Improve flat store: MemRegion::getAsOffset() computes a region's offset within 
the top-level object. FlatStore now can bind and retrieve element and field
regions.
PR7297 is fixed by flat store.

llvm-svn: 110020
 2010-08-02 04:56:14 +00:00
Daniel Dunbar 7fbaf53470 Driver: Add Compilation::addCommand and switch tools to using it, now that we 
don't have to deal with nested jobs.

llvm-svn: 110015
 2010-08-02 02:38:28 +00:00
Daniel Dunbar b785d74080 Driver: Eliminate PipedJob, which is now unused. 
llvm-svn: 110014
 2010-08-02 02:38:25 +00:00
Daniel Dunbar b440f56e53 Driver: Eliminate special InputInfo kind for pipes, it is now unused. 
llvm-svn: 110013
 2010-08-02 02:38:21 +00:00
Daniel Dunbar bffefc015e Driver: Eliminate now unnecessary tool hooks for whether they accept piped input/output. 
llvm-svn: 110012
 2010-08-02 02:38:18 +00:00
Daniel Dunbar d00272f6d6 Driver: Simplify. 
llvm-svn: 110011

Daniel Dunbar c12a412cb6 Driver: Eliminate now unused argument. 
llvm-svn: 110010
 2010-08-02 02:38:12 +00:00
Daniel Dunbar 89f791e2c2 Driver: Simplify logic for sending 'clang -E t.c' output to stdout. 
llvm-svn: 110009
 2010-08-02 02:38:08 +00:00
Daniel Dunbar a7dd15888b Driver: Never try to use piped inputs. 
llvm-svn: 110008
 2010-08-02 02:38:06 +00:00
Daniel Dunbar 926f81fce5 Driver: Start ripping out support for -pipe, which is worthless and complicates 
too many other things.

llvm-svn: 110007

Daniel Dunbar ea3813fbc9 Driver/OpenBSD: Update toolchain for compiler changes / C++; patch by Jonathan 
Gray.

llvm-svn: 109994
 2010-08-01 23:13:54 +00:00
Daniel Dunbar 88979914d7 Driver: Keep track of a separate "install dir", which is the path where clang 
was invoked from (which may not be where the executable itself is).
 - This allows having e.g., /Developer/usr/bin/clang be a symlink to some other
   location, while still making sure the Driver finds 'as', 'ld', etc. relative
   to itself.

llvm-svn: 109989
 2010-08-01 22:29:51 +00:00

Eli Friedman 60307d2072 PR7777: Set EnabledByDefault to something useful, instead of setting it 
randomly.  This makes us consistently show "-pedantic" as the warning option
for a warning where appropriate.

John McCall 81c9cea24b Kill off RequiresGlobalConstructor in favor of isConstantInitializer. 
Note some obvious false positives in the test case.
