2009-04-29retain/release checker: Hoist code for bug reports above transfer function logicTed Kremenek

2009-04-29PR4103: improve source location information for members of the current Eli Friedman

2009-04-29Add test case for transfer function logic for OSCompareAndSwap32Barrier.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70383 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-29Add corner case logic to BasicStoreManager and GRSimpleVals::EvalBinOp to enableTed Kremenek
reasoning about OSCompareAndSwap32Barrier/OSCompareAndSwap64Barrier. Essentially the address of reference to a region (pointer-to-pointer) can be casted to (int32_t*), and we need to handle the logic to convert the involved locations back and forth from nonloc::LocAsInteger, nonloc::ConcreteInt, to Loc and loc::ConcreteInt respectively. This adds some potentially suspect logic to BasicStoreManager that allows the analyzer to reason about abuses of the C type system. This should probably be refined, be ported over to RegionStoreManager, and extended with "path-sensitive type checking" to flag bugs in clearly incoherent code. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70382 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-29fix PR4021, array and functions decay in the receiver position of an objc ↵Chris Lattner
message send. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70373 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-29Fix PR4092 by improving error recovery in two ways:Chris Lattner
1. In a struct field redefinition, don't mark the struct erroneous. The field is erroneous, but the struct is otherwise well formed. 2. Don't emit diagnostics about functions that are known to be broken already. Either fix is sufficient to silence the second diagnostic in the example, but the combination is better :) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70371 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-29implement -Wformat-security properly, which is enabled by default.Chris Lattner
This enables one specific class of non-literal format warnings. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70368 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-29add a bunch of individual warnings to -Wformat (which isChris Lattner
on by default). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70365 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-29-Wformat should depend on format-extra-args so that -Wformat impliesChris Lattner
the extra argument warnings, and -Wformat -Wno-format-extra-args turns on -Wformat but not the extra-args warnings. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70363 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-29tweak warning options to be more like gcc:Chris Lattner
1. All all variants of -Wformat*, make them imply -Wformat. GCC warns if you use -Wformatfoo without -Wformat. We just make one imply the other. 2. Make -Wformat-nonliteral default to off, like gcc. It is an incredible nuisance. 3. Accept but currently ignore -Wformat-extra-args. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70362 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-28Optimize IdentifierInfo storage within the precompiled header. We'veDouglas Gregor
now gotten back about 180k of the 500k we lost. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70326 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-28Implement a minor space optimization for the PCH identifier table,Douglas Gregor
which eliminates the storage for IdentifierInfo in the "uninteresting identifier" cases. Sadly, this only brought back 7k of the 500k we lost :( git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70325 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-28Implement checking for macro definitions that occur on the commandDouglas Gregor
line when using a PCH that were not provided when building the PCH file. If those names were used as identifiers somewhere in the PCH file, reject the PCH file. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70321 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-28Revert r70075 and r70078, which reorganized the PCH on-disk hash tableDouglas Gregor
for identifiers to separate "interesting" from "uninteresting" identifiers. However, to cope with compiler invocations where the predefines buffers mismatch, we need to be able to search the complete identifier table. Cocoa.h.pch is now about 500k larger that it used to be :( git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70320 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-28With -ccc-pch-is-pch, always treat precompiled inputs as PCH,Daniel Dunbar
regardless of extension. - Otherwise we can't expect that just plugging in -ccc-pch-is-pch will work. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70318 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-28Allow some differences between the predefines buffer used to build aDouglas Gregor
PCH file and the predefines buffer used when including the PCH file. We (explicitly) detect conflicting macro definitions (rejecting the PCH file) and about missing macro definitions (they'll be automatically pulled from the PCH file anyway). We're missing some checking to make sure that new macro definitions won't have any impact on the PCH file itself (e.g., #define'ing an identifier that the PCH file used). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70316 91177308-0d34-0410-b5e6-96231b3b80d8
