* Driver: Don't forward any -g options to GCC, when using it to drive theDaniel Dunbar2010-08-031-0/+5
| | | | | | | assembler. - Fixes PR6218, hopefully. llvm-svn: 110111
* Reshuffle the PCH generator action and consumer, so that we can re-useDouglas Gregor2010-08-033-41/+77
| | | | | | it while generating precompiled preambles. No functionality change. llvm-svn: 110108
* Emit weak vtables of non-template classes with hidden visibility.John McCall2010-08-031-0/+16
| | | | llvm-svn: 110107
* Allow offsets to be negative. Out-of-bound cases are checked elsewhere. We Zhongxing Xu2010-08-032-6/+5
| | | | | | shouldn't put restrictions in store manager. llvm-svn: 110106
* Pull the region offset computation logic into a single method.Zhongxing Xu2010-08-032-43/+60
| | | | llvm-svn: 110102
* Changed GRExprEngine to pass down a reference to itself when checkers are ↵Tom Care2010-08-033-9/+9
| | | | | | | | | 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 llvm-svn: 110095
* Add -cc1 option '-unoptimized-cfg' to toggle using a CFG (for static ↵Ted Kremenek2010-08-034-3/+9
| | | | | | analysis) that doesn't prune CFG edges. llvm-svn: 110087
* Add 'AnalysisContext::getUnoptimizedCFG()' to allow clients to get access to ↵Ted Kremenek2010-08-022-21/+46
| | | | | | | | the original CFG without any edges pruned out because of trivially solvable conditions (e.g., 'if (0)'). llvm-svn: 110085
* Labels (and case statement) don't create independent scope parents for theJohn McCall2010-08-021-16/+18
| | | | | | | | purposes of the jump checker. Also extend Ted's iteration fix to labels. Fixes PR7789. llvm-svn: 110082
* Simplify global method pool implementation in Sema. No functionality change.Sebastian Redl2010-08-025-207/+110
| | | | llvm-svn: 110078
* Fix another case (this time in JumpScopeChecker) where walking deeply nested ↵Ted Kremenek2010-08-021-1/+11
| | | | | | CaseStmts can blow out the stack. Fixes <rdar://problem/8125165>. llvm-svn: 110071
* Fix idempotent operations false positive caused by ivars not being ↵Ted Kremenek2010-08-021-2/+11
| | | | | | | | invalidated in function calls when the enclosing object had retain/release state. Fixes <rdar://problem/8261992>. llvm-svn: 110068
* Further adjustments to -Wglobal-constructors; works for references and directJohn McCall2010-08-025-25/+46
| | | | | | initializations now. llvm-svn: 110063
* When using a precompiled preamble, save the diagnostics produced whenDouglas Gregor2010-08-021-15/+41
| | | | | | | | 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. llvm-svn: 110061
* 'Assumption &A' gets default initialized to 'Possible' if it doesn't exist; ↵Ted Kremenek2010-08-021-8/+5
| | | | | | | | no need to two lookups in the hashtable. llvm-svn: 110059
* Query only the latest version of an identifier in the PCH chain. Make sure ↵Sebastian Redl2010-08-022-22/+7
| | | | | | 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
* Remove mutable data on TagType and InjectedClassNameType, by instead walking ↵Sebastian Redl2010-08-022-20/+26
| | | | | | 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. llvm-svn: 110051
* Compute width/align of objc builtin types (id, etc)Fariborz Jahanian2010-08-021-0/+6
| | | | | | for radar 8258797. llvm-svn: 110047
* Read/write in PCH Sema's StdNamespace and StdBadAlloc and use a LazyDeclPtr ↵Argyrios Kyrtzidis2010-08-027-16/+52
| | | | | | for them that will deserialize them when needed. llvm-svn: 110031
* Rename getStdNamespace -> getOrCreateStdNamespace, to better reflect its ↵Argyrios Kyrtzidis2010-08-023-4/+4

* Driver/Darwin: Change where Darwin computes the host version, to normalize toolDaniel Dunbar2010-08-023-30/+25
| | | | | | chain construction. llvm-svn: 110028
* Driver: Have -ccc-host-triple simply override the default in the driver, forDaniel Dunbar2010-08-021-3/+4
| | | | | | now. llvm-svn: 110027
* Driver/Darwin: Inline some constants.Daniel Dunbar2010-08-023-17/+7
| | | | llvm-svn: 110026
* Driver/FreeBSD: Change how FreeBSD derives the Lib32 variable, to normalize toolDaniel Dunbar2010-08-023-12/+11

* Driver: Move HostInfo::lookupTypeForExtension to ↵Daniel Dunbar2010-08-025-49/+17
| | | | | | ToolChain::LookupTypeForExtension. llvm-svn: 110024
* Driver: Give Build{Universal,}Actions access to the default host tool chain. IDaniel Dunbar2010-08-021-9/+9
| | | | | | | 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
* Improve flat store: MemRegion::getAsOffset() computes a region's offset withinZhongxing Xu2010-08-025-17/+88
| | | | | | | | the top-level object. FlatStore now can bind and retrieve element and field regions. PR7297 is fixed by flat store. llvm-svn: 110020
* Driver: Add Compilation::addCommand and switch tools to using it, now that weDaniel Dunbar2010-08-023-67/+45
| | | | | | don't have to deal with nested jobs. llvm-svn: 110015
* Driver: Eliminate PipedJob, which is now unused.Daniel Dunbar2010-08-022-23/+1
| | | | llvm-svn: 110014
* Driver: Eliminate special InputInfo kind for pipes, it is now unused.Daniel Dunbar2010-08-022-135/+35

* Driver: Eliminate now unused argument.Daniel Dunbar2010-08-021-4/+2
| | | | llvm-svn: 110010
* Driver: Simplify logic for sending 'clang -E t.c' output to stdout.Daniel Dunbar2010-08-021-25/+4
| | | | llvm-svn: 110009
* Driver: Never try to use piped inputs.Daniel Dunbar2010-08-021-7/+2
| | | | llvm-svn: 110008
* Driver: Start ripping out support for -pipe, which is worthless and complicatesDaniel Dunbar2010-08-021-17/+4
| | | | | | too many other things. llvm-svn: 110007
* Driver/OpenBSD: Update toolchain for compiler changes / C++; patch by JonathanDaniel Dunbar2010-08-012-1/+19
| | | | | | Gray. llvm-svn: 109994
* Driver: Keep track of a separate "install dir", which is the path where clangDaniel Dunbar2010-08-011-5/+15
| | | | | | | | | 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
* PR7777: Set EnabledByDefault to something useful, instead of setting itEli Friedman2010-08-011-1/+1
| | | | | | | randomly. This makes us consistently show "-pedantic" as the warning option for a warning where appropriate. llvm-svn: 109987
* Kill off RequiresGlobalConstructor in favor of isConstantInitializer.John McCall2010-08-012-53/+17
| | | | | | Note some obvious false positives in the test case. llvm-svn: 109986
* Make a first pass at implementing -Wglobal-constructors. I'm worried that thisJohn McCall2010-08-012-1/+67
| | | | | | | will end up bizarrely mirroring CGExprConstant, but that might be the hazard of this feature. llvm-svn: 109984
* Instantiate attributes from the pattern record when instantiatingJohn McCall2010-08-013-13/+18
| | | | | | a class template. Fixes rdar://problem/8243419. llvm-svn: 109967

| | | | llvm-svn: 109965
* Don't consider all local variables in C++ to mandate scope-checking, justJohn McCall2010-08-011-2/+10
| | | | | | those with initializers. llvm-svn: 109964
* Only run the jump-checker if there's a branch-protected scope *and* there'sJohn McCall2010-08-014-20/+54
| | | | | | | | | | a switch or goto somewhere in the function. Indirect gotos trigger the jump-checker regardless, because the conditions there are slightly more elaborate and it's too marginal a case to be worth optimizing. Turns off the jump-checker in a lot of cases in C++. rdar://problem/7702918 llvm-svn: 109962
* Fix fragile-ABI ObjC exceptions in the presence of optimization withJohn McCall2010-07-311-3/+165
| | | | | | | | | the magic of inline assembly. Essentially we use read and write hazards on the set of local variables to force flushing locals to memory immediately before any protected calls and to inhibit optimizing locals across the setjmp->catch edge. Fixes rdar://problem/8160285 llvm-svn: 109960
* Parser: Add support for #pragma align, which is just another spelling of #pragmaDaniel Dunbar2010-07-313-13/+40
