2010-10-12Parse default arguments within member functions in source order, fromDouglas Gregor
Manuel Klimek! Fixes PR7715. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116311 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-12When we load an ASTUnit from command-line arguments, hold on to theDouglas Gregor
diagnostics produced by the driver itself. Previously, we were allowing these to either be dropped or to slip through to stderr. Fixes <rdar://problem/7595339>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116285 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-11Switch c-index-test from clang_codeComplete() over toDouglas Gregor
clang_codeCompleteAt(). This uncovered a few issues with the latter: - ASTUnit wasn't saving/restoring diagnostic state appropriately between reparses and code completions. - "Overload" completions weren't being passed through to the client git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116241 91177308-0d34-0410-b5e6-96231b3b80d8
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

2010-10-06Fix a double-free error that can occur in rare cases where loadingDouglas Gregor
of the precompiled preamble (or any PCH file it depends on) fails during reparsing. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@115838 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-01Enable chained precompiled headers for use with precompiled preamblesDouglas Gregor
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@115260 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-27Remove libclang logging codeDouglas Gregor
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114836 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
2010-09-24Teach libclang to enable multithreading in LLVM, since libclang clients are ↵Douglas Gregor
likely to be multithreaded. Also move the printing of timers to somewhere better for multithreaded libclang clients git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114760 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
2010-09-14Introduce a new code-completion context for a parenthesizedDouglas Gregor
expression, e.g., after the '(' that could also be a type cast. Here, we provide types as code-completion results in C/Objective-C (C++ already had them), although we wouldn't in a normal expression context. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@113904 91177308-0d34-0410-b5e6-96231b3b80d8
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
2010-09-11If we fail to create a temporary file for the precompiled preamble,Douglas Gregor
just abort creation of the precompiled preamble rather than doing silly things. This is the second part of the fix for the weird preamble-related failures on Windows. Big thanks to Francois Pichet for the great detective work! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@113697 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-11Tweak GetPreamblePCHPath() to more closely match the behavior of theDouglas Gregor
Windows GetTempPath() function, and be sure to create the directory in which the precompiled preamble will reside before creating the temporary file itself. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@113695 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-26Move the sorting of code-completion results out of the main path andDouglas Gregor
into the clients, e.g., the printing code-completion consumer and c-index-test. Clients may want to re-sort the results anyway. Provide a libclang function that sorts the results. 3rd try. How embarrassing. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112180 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-26Revert "Move the sorting of code-completion results out of the main path andDouglas Gregor

2010-08-25When combining the code-completion results from Sema long with theDouglas Gregor
code-completion results cached by ASTUnit, sort the resulting result set. This makes testing far, far easier, so this commit also includes tests for the previous few fixes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112070 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-23Introduce a new code-completion point when we're parsing aDouglas Gregor
declarator. Here, we can only see a few things (e.g., cvr-qualifiers, nested name specifiers) and we do not want to provide other non-macro completions. Previously, we would end up in recovery mode and would provide a large number of non-relevant completions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111818 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-20When performing code-completion in the presence of a preamble, makeDouglas Gregor
