* Teach libclang to enable multithreading in LLVM, since libclang clients are ↵Douglas Gregor2010-09-241-0/+3
| | | | | | likely to be multithreaded. Also move the printing of timers to somewhere better for multithreaded libclang clients llvm-svn: 114760
* Synchronize globally-cached code completion results with the resultsDouglas Gregor2010-09-231-4/+6
| | | | | | | | | | | | | | 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>. llvm-svn: 114704
* Tweak priorities for some types and macros:Douglas Gregor2010-09-201-0/+1
| | | | | | | | | | - 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. llvm-svn: 114356
* Introduce a new code-completion context for a parenthesizedDouglas Gregor2010-09-141-5/+12
| | | | | | | | 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. llvm-svn: 113904
* The two libclang crash-recovery tests that involve precompiledDouglas Gregor2010-09-111-0/+7
| | | | | | | | | | 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. llvm-svn: 113698
* If we fail to create a temporary file for the precompiled preamble,Douglas Gregor2010-09-111-1/+10
| | | | | | | | | 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! llvm-svn: 113697
* Tweak GetPreamblePCHPath() to more closely match the behavior of theDouglas Gregor2010-09-111-0/+5
| | | | | | | | Windows GetTempPath() function, and be sure to create the directory in which the precompiled preamble will reside before creating the temporary file itself. llvm-svn: 113695

| | | | | | | | | | | 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. llvm-svn: 112180

* Revert "Move the sorting of code-completion results out of the main path andDouglas Gregor2010-08-261-1/+3

* When combining the code-completion results from Sema long with theDouglas Gregor2010-08-251-2/+6
| | | | | | | | 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. llvm-svn: 112070

| | | | | | | code completion. We were allowing the preamble to include the line that we're code-completing on. Again, testcase is forthcoming. llvm-svn: 112064
* Make the cursor kind of macro-name-only completions produced byDouglas Gregor2010-08-251-1/+4

* Implement preprocessor code completion where a macro name is expected,Douglas Gregor2010-08-241-5/+22
| | | | | | | e.g., after #ifdef/#ifndef or #undef, or inside a defined <macroname> expression in a preprocessor conditional. llvm-svn: 111954
* Introduce new libclang API functions that determine the availabilityDouglas Gregor2010-08-231-1/+4
| | | | | | | of a cursor or code-completion result, e.g., whether that result refers to an unavailable, deleted, or deprecated declaration. llvm-svn: 111858
* Don't include macro results when we're completing a declarator.Douglas Gregor2010-08-231-3/+1
| | | | llvm-svn: 111830
* Introduce a new code-completion point when we're parsing aDouglas Gregor2010-08-231-2/+8
| | | | | | | | | 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. llvm-svn: 111818
* Abstract out member-pointer creation. I'm really unhappy about the currentJohn McCall2010-08-221-1/+1
| | | | | | | | duplication between the constant and non-constant paths in all of this. Implement ARM ABI semantics for member pointer constants and conversion. llvm-svn: 111772
* When performing code-completion in the presence of a preamble, makeDouglas Gregor2010-08-201-8/+13
| | | | | | | | | sure to (1) actually use the remapped files we were given rather than old data, and (2) keep the remapped files alive until the code-completion results are destroyed. Big thanks to Daniel for the test case. llvm-svn: 111597
* When we decide not to reuse a precompiled preamble, clear out theDouglas Gregor2010-08-201-2/+18
| | | | | | previous precompiled preamble completely. Fixes <rdar://problem/8330950>. llvm-svn: 111590
* Fix a loop overrun in ComputePreamble when the last remapped file was erased,Daniel Dunbar2010-08-191-0/+4
| | | | | | | | and reenable crash recovery test. - Reparsing is still very crashy / weird, so I had to sprinkle random code into the remapped input to get it to do what I want (i.e., crash!). llvm-svn: 111550

* When creating an ASTUnit by parsing source code, set DisableFree toDouglas Gregor2010-08-181-1/+1
| | | | | | | | false (not true), so that the CompilerInstance will actually free data structures when it's done. This fixes a major leak with libclang's in-process code completion. llvm-svn: 111457
* Simplify the ownership model for DiagnosticClients, which was reallyDouglas Gregor2010-08-181-18/+16
| | | | | | | convoluted and a bit leaky. Now, the Diagnostic object owns its DiagnosticClient. llvm-svn: 111437

* Create a new Serialization module that contains all the PCH code, and will ↵Sebastian Redl2010-08-171-2/+2
| | | | | | contain all the module code in the future. Update the Makefiles, CMake projects and the Xcode project. I hope I did everything right for Xcode. No functionality change. llvm-svn: 111258
* When the # of top-level declarations changes after reparsing aDouglas Gregor2010-08-171-1/+15
| | | | | | | | translation unit, refresh code-completion results because they've probably changed. However, enforce a cooldown period between refreshes, to avoid thrashing. llvm-svn: 111218

| | | | llvm-svn: 111204
* Implement support for cached code completions forDouglas Gregor2010-08-161-21/+51
| | | | | | | | | | nested-name-specifiers. Also includes fixes to the generation of nested-name-specifier result in the non-cached case; we were producing lame results for namespaces and namespace aliases, which (1) didn't always have nested-name-specifiers when we want them, and (2) did not have the necessary "::" as part of the completion. llvm-svn: 111203

* When caching code completions for global declarations, keep track ofDouglas Gregor2010-08-161-8/+38
| | | | | | | | | | | | | | | | the usage type of each declaration result, then compare those types to the preferred type of the completion. This provides parity in the priority calculation between the code-completion results produced directly from Sema and those cached by ASTUnit. For the standard Cocoa.h (+ others) example, there's a penalty of 3-4 hundredeths of a second when caching the global results (for ~31,000 results), because we need an ASTContext-agnostic representation of types for the comparison, and therefore we use... strings. Eventually, we'd like to implement a more efficient ASTContext-agnostic encoding of types. llvm-svn: 111165
* Dereferencing NULL pointers is such poor form.Douglas Gregor2010-08-161-4/+8
| | | | llvm-svn: 111150
* When caching global completion results, keep track of the simplifiedDouglas Gregor2010-08-161-1/+23
| | | | | | | | | | | type class, so that we can adjust priorities appropriately when the preferred type for the context and the actual type of the completion are similar. This gets us one step closer to parity of the cached completion results with the non-cached completion results. llvm-svn: 111139
