2010-10-24Put the mechanism in place to track modifications in an AST entity that were ↵Argyrios Kyrtzidis
committed after its initial creation/deserialization and store the changes in a chained PCH. The idea is that the AST entities call methods on the ASTMutationListener to give notifications of changes; the PCHWriter implements the ASTMutationListener interface and stores the incremental changes of the updated entity. WIP git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@117235 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-18"Fix" bogus idempotent operations warning due to loop unrolling not ↵Ted Kremenek
unrolling enough loops to show that an invariant doesn't hold. This fix is to increase the loop unrolling count to 4, which experiments show doesn't typically impact analysis time. The real fix is to modify the IdempotentOperationsChecker to suppress warnings where an analysis point could be preceded by a point where we gave up due to loop unrolling. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116769 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-12When we load an ASTUnit from command-line arguments, hold on to theDouglas Gregor

2010-10-08Fix three related, wily issues with the recompilation of precompiledDouglas Gregor
preambles: - When we rebuild a precompiled preamble, make sure to disable skipping anything in the main file; we may have had leftover preamble-skipping values in the lexer, which leads to very empty preamble. This is a correctness issue. - When we rebuild a precompiled preamble, clear out any prior state in the Diagnostic object. Otherwise, we might think that there were errors when we were building the preamble itself, and therefore reject the resulting preamble. This is mainly a performance issue. - Don't remove old remappings when digging out the remapping for the main file. Having the old mappings around does not hurt in the common case (later remappings will just overwrite them), and is important when we fail to find a preamble: we don't want to have removed the remapping, because we'll need it later. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116041 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-24When setting the globally-visible declarations for a particularDouglas Gregor
identifier, we may have a Sema object but no translation unit scope (because parsing is finished). In this case, we still need to update the IdResolver, which might still be used when writing a PCH containing another PCH (without chaining). This bug manifested as a failure with precompiled preambles. Also, add a little environment-variable-sensitive logging for libclang. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114774 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-23Synchronize globally-cached code completion results with the resultsDouglas Gregor
provided when the optimization is disabled. In particular, split the completion context CCC_Other into two contexts: CCC_Other, which means that it's an undisclosed context for which any other results are unwelcome, and CCC_Recovery, which is used in recovery cases. Since we're now using the completion context within the completion results builder, make sure that it's always set to something. Fixes <rdar://problem/8470644>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114704 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-20Tweak priorities for some types and macros:Douglas Gregor
- In Objective-C, we prefer BOOL to bool for historic reasons; slightly penalize "bool". - Treat Nil macro as a NULL pointer constant. - Treat YES, NO, true, and false macros as constants. - Treat the bool macro as a type. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114356 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-17Add a -ftrapv-handler= option which allows a handler to invoke instead of ↵David Chisnall
simply aborting when a signed operation overflows. This mirrors the (GCC-incompatible) behaviour from clang 1.0 and 1.1 when -ftrapv was specified, but allows the handler to be defined for each compilation unit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114192 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-14Introduce a new code-completion context for a parenthesizedDouglas Gregor

2010-09-11The two libclang crash-recovery tests that involve precompiledDouglas Gregor
preambles end up leaving the precompiled preambles around. This is by design, since we do minimal cleanup during crash recovery. However, it's unfortunate for testing, so introduce a hook that allows these two tests to put the precompiled preamble somewhere where we can delete them after testing. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@113698 91177308-0d34-0410-b5e6-96231b3b80d8
