#include "clang/Frontend/ASTUnit.h"

Add ASTUnit::LoadFromCompilerInvocation, which does what it says. Also, add an -ast-from-source option to index-test which allows index-test to run on source files directly. llvm-svn: 90223

#include "clang/AST/DeclVisitor.h"
When caching code completions for global declarations, keep track of 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

Add ASTUnit::LoadFromCommandLine, which creates an ASTUnit out of a list of (clang/driver) command line arguments (including the source file). - The arguments are expected to include the source file. - The idea is that even though this is a somewhat odd API, its the form which many tools can most easily use (for example, by interposing with the compiler). Also, switch index-test's -ast-from-source to use this entry point, and provide a -arg command line argument which can be used to test that the command line arguments are handled correctly. llvm-svn: 90288

Switch c-index-test from clang_codeComplete() over to clang_codeCompleteAt().

Introduce a flag in SourceManager to treat non-system source files as "volatile", meaning there's a high enough chance that they may change while we are trying to use them. This flag is only enabled by libclang. Currently "volatile" source files will be stat'ed immediately before opening them, because the file size stat info may not be accurate since when we got it (e.g. from the PCH). This avoids crashes when trying to reference mmap'ed memory from a file whose size is not what we expect. Note that there's still a window for a racing issue to occur but the window for it should be way smaller than before. We can consider later on to avoid mmap completely on such files. rdar://11612916 llvm-svn: 160074

Introduce basic support for loading a precompiled preamble while reparsing an ASTUnit. When saving a preamble, create a buffer larger than the actual file we're working with but fill everything from the end of the preamble to the end of the file with spaces (so the lexer will quickly skip them). When we load the file, create a buffer of the same size, filling it with the file and then spaces. Then, instruct the lexer to start lexing after the preamble, therefore continuing the parse from the spot where the preamble left off. It's now possible to perform a simple preamble build + parse (+ reparse) with ASTUnit. However, one has to disable a bunch of checking in the PCH reader to do so. That part isn't committed; it will likely be handled with some other kind of flag (e.g., -fno-validate-pch). As part of this, fix some issues with null termination of the memory buffers created for the preamble; we were trying to explicitly NULL-terminate them, even though they were also getting implicitly NULL terminated, leading to excess warnings about NULL characters in source files. llvm-svn: 109445

Improve crash recovery cleanup to recovery CompilerInstances during crash recovery. This was a huge resource "root" during crashes.

Extend the code-completion caching infrastructure to include global declarations (in addition to macros). Each kind of declaration maps to a certain set of completion contexts, and the ASTUnit completion logic introduces the completion strings for those declarations if the actual code-completion occurs in one of the contexts where it matters. There are a few new code-completion-context kinds. Without these, certain completions (e.g., after "using namespace") would need to suppress all global completions, which would be unfortunate. Note that we don't get the priorities right for global completions, because we don't have enough type information. We'll need a way to compare types in an ASTContext-agnostic way before this can be implemented. llvm-svn: 111093

Implement caching of code-completion results for macro definitions when the CXTranslationUnit_CacheCompletionResults option is given to clang_parseTranslationUnit(). Essentially, we compute code-completion results for macro definitions after we have parsed the file, then store an ASTContext-agnostic version of those results (completion string, cursor kind, priority, and active contexts) in the ASTUnit. When performing code completion in that ASTUnit, we splice the macro definition results into the results provided by the actual code-completion (which has had macros turned off) before libclang gets those results. We use completion context information to only splice in those results that make sense for that context. With a completion involving all of the macros from Cocoa.h and a few other system libraries (totally ~8500 macro definitions) living in a precompiled header, we get about a 9% performance improvement from code completion, since we no longer have to deserialize all of the macro definitions from the precompiled header. Note that macro definitions are merely the canary; the cache is designed to also support other top-level declarations, which should be a bigger performance win. That optimization will be next. Note also that there is no mechanism for determining when to throw away the cache and recompute its contents. llvm-svn: 111051

Implement caching of code-completion results for macro definitions when the CXTranslationUnit_CacheCompletionResults option is given to clang_parseTranslationUnit(). Essentially, we compute code-completion results for macro definitions after we have parsed the file, then store an ASTContext-agnostic version of those results (completion string, cursor kind, priority, and active contexts) in the ASTUnit. When performing code completion in that ASTUnit, we splice the macro definition results into the results provided by the actual code-completion (which has had macros turned off) before libclang gets those results. We use completion context information to only splice in those results that make sense for that context. With a completion involving all of the macros from Cocoa.h and a few other system libraries (totally ~8500 macro definitions) living in a precompiled header, we get about a 9% performance improvement from code completion, since we no longer have to deserialize all of the macro definitions from the precompiled header. Note that macro definitions are merely the canary; the cache is designed to also support other top-level declarations, which should be a bigger performance win. That optimization will be next. Note also that there is no mechanism for determining when to throw away the cache and recompute its contents. llvm-svn: 111051

Implement caching of code-completion results for macro definitions when the CXTranslationUnit_CacheCompletionResults option is given to clang_parseTranslationUnit(). Essentially, we compute code-completion results for macro definitions after we have parsed the file, then store an ASTContext-agnostic version of those results (completion string, cursor kind, priority, and active contexts) in the ASTUnit. When performing code completion in that ASTUnit, we splice the macro definition results into the results provided by the actual code-completion (which has had macros turned off) before libclang gets those results. We use completion context information to only splice in those results that make sense for that context. With a completion involving all of the macros from Cocoa.h and a few other system libraries (totally ~8500 macro definitions) living in a precompiled header, we get about a 9% performance improvement from code completion, since we no longer have to deserialize all of the macro definitions from the precompiled header. Note that macro definitions are merely the canary; the cache is designed to also support other top-level declarations, which should be a bigger performance win. That optimization will be next. Note also that there is no mechanism for determining when to throw away the cache and recompute its contents. llvm-svn: 111051

Allocate CodeCompletionString and all of its components in a BumpPtrAllocator, rather than manually new/delete'ing them. This optimization also allows us to avoid allocating memory for and copying constant strings (e.g., "return", "class").

[code-complete] Introduce CodeCompletionTUInfo which will be used for caching code-completion related strings specific to a translation unit (ASTContext and related data) CodeCompletionAllocator does such limited caching, by caching the name assigned to a DeclContext*, but that is not the appropriate place since that object has a lifetime that can extend beyond that of an ASTContext. Introduce CodeCompletionTUInfo which will be always tied to a translation unit to do this kind of caching and move the caching of CodeCompletionAllocator into this object, and propagate it to all the places where it will be needed. The plan is to extend the caching where appropriate, using CodeCompletionTUInfo, to avoid re-calculating code-completion strings. Part of rdar://10796159. llvm-svn: 154408

*CachedCompletionAllocator,
Add a new libclang completion API to get brief documentation comment that is attached to a declaration in the completion string. Since extracting comments isn't free, a new code completion option is introduced. A new code completion option that enables including brief comments into CodeCompletionString should be a, err, code completion option. But because ASTUnit caches global declarations during parsing before even completion consumer is created, the option is duplicated as a translation unit option (in both libclang and ASTUnit, like the option to cache code completion results). llvm-svn: 159539

Introduce a flag in SourceManager to treat non-system source files as "volatile", meaning there's a high enough chance that they may change while we are trying to use them. This flag is only enabled by libclang. Currently "volatile" source files will be stat'ed immediately before opening them, because the file size stat info may not be accurate since when we got it (e.g. from the PCH). This avoids crashes when trying to reference mmap'ed memory from a file whose size is not what we expect. Note that there's still a window for a racing issue to occur but the window for it should be way smaller than before. We can consider later on to avoid mmap completely on such files. rdar://11612916 llvm-svn: 160074

Keep track of whether declararions were loaded from a precompiled header or not via a new "PCHLevel" field in Decl.

Improve ASTUnit's capture of diagnostics so that the diagnostic-capturing client lives as long as the ASTUnit itself does.

Improve crash recovery cleanup to recovery CompilerInstances during crash recovery. This was a huge resource "root" during crashes.

Introduce a flag in SourceManager to treat non-system source files as "volatile", meaning there's a high enough chance that they may change while we are trying to use them.

This avoids crashes when trying to reference mmap'ed memory from a file whose size is not what we expect. Note that there's still a window for a racing issue to occur but the window for it should be way smaller than before. We can consider later on to avoid mmap completely on such files. rdar://11612916 llvm-svn: 160074

Make 'LangOptions' in CompilerInvocation a heap-allocated, reference counted object. I discovered that llvm::RefCountedBase<T> has a bug where the reference count is copied in the copy constructor, which means that there were cases when the CompilerInvocation objects created by ASTUnit were actually leaked. When I fixed that bug locally, it showed that a whole bunch of code assumed that the LangOptions object that was part of CompilerInvocation was still alive. By making it heap-allocated and reference counted, we can keep it around after the CompilerInvocation object goes away. As part of this change, change CompilerInvocation:getLangOptions() to return a pointer, acting as another clue that this object may outlive the CompilerInvocation object. This commit doesn't fix the CompilerInvocation leak itself. That will come when I commit the fix to llvm::RefCountedBase<T> to mainline LLVM. llvm-svn: 144930

Introduce a flag in SourceManager to treat non-system source files as "volatile", meaning there's a high enough chance that they may change while we are trying to use them. This flag is only enabled by libclang. Currently "volatile" source files will be stat'ed immediately before opening them, because the file size stat info may not be accurate since when we got it (e.g. from the PCH). This avoids crashes when trying to reference mmap'ed memory from a file whose size is not what we expect. Note that there's still a window for a racing issue to occur but the window for it should be way smaller than before. We can consider later on to avoid mmap completely on such files. rdar://11612916 llvm-svn: 160074

Introduce basic support for loading a precompiled preamble while reparsing an ASTUnit. When saving a preamble, create a buffer larger than the actual file we're working with but fill everything from the end of the preamble to the end of the file with spaces (so the lexer will quickly skip them). When we load the file, create a buffer of the same size, filling it with the file and then spaces. Then, instruct the lexer to start lexing after the preamble, therefore continuing the parse from the spot where the preamble left off. It's now possible to perform a simple preamble build + parse (+ reparse) with ASTUnit. However, one has to disable a bunch of checking in the PCH reader to do so. That part isn't committed; it will likely be handled with some other kind of flag (e.g., -fno-validate-pch). As part of this, fix some issues with null termination of the memory buffers created for the preamble; we were trying to explicitly NULL-terminate them, even though they were also getting implicitly NULL terminated, leading to excess warnings about NULL characters in source files. llvm-svn: 109445

Revamp the SourceManager to separate the representation of parsed source locations from source locations loaded from an AST/PCH file. Previously, loading an AST/PCH file involved carefully pre-allocating space at the beginning of the source manager for the source locations and FileIDs that correspond to the prefix, and then appending the source locations/FileIDs used for parsing the remaining translation unit. This design forced us into loading PCH files early, as a prefix, whic has become a rather significant limitation. This patch splits the SourceManager space into two parts: for source location "addresses", the lower values (growing upward) are used to describe parsed code, while upper values (growing downward) are used for source locations loaded from AST/PCH files. Similarly, positive FileIDs are used to describe parsed code while negative FileIDs are used to file/macro locations loaded from AST/PCH files. As a result, we can load PCH/AST files even during parsing, making various improvemnts in the future possible, e.g., teaching #include <foo.h> to look for and load <foo.h.gch> if it happens to be already available.

The two libclang crash-recovery tests that involve precompiled preambles end up leaving the precompiled preambles around. This is by design, since we do minimal cleanup during crash recovery.

Introduce basic support for loading a precompiled preamble while reparsing an ASTUnit. When saving a preamble, create a buffer larger than the actual file we're working with but fill everything from the end of the preamble to the end of the file with spaces (so the lexer will quickly skip them). When we load the file, create a buffer of the same size, filling it with the file and then spaces. Then, instruct the lexer to start lexing after the preamble, therefore continuing the parse from the spot where the preamble left off. It's now possible to perform a simple preamble build + parse (+ reparse) with ASTUnit. However, one has to disable a bunch of checking in the PCH reader to do so. That part isn't committed; it will likely be handled with some other kind of flag (e.g., -fno-validate-pch). As part of this, fix some issues with null termination of the memory buffers created for the preamble; we were trying to explicitly NULL-terminate them, even though they were also getting implicitly NULL terminated, leading to excess warnings about NULL characters in source files. llvm-svn: 109445

Implement -working-directory. When -working-directory is passed in command line, file paths are resolved relative to the specified directory. This helps both when using libclang (where we can't require the user to actually change the working directory) and to help reproduce test cases when the reproduction work comes along. --FileSystemOptions is introduced which controls how file system operations are performed (currently it just contains the working directory value if set). --FileSystemOptions are passed around to various interfaces that perform file operations. --Opening & reading the content of files should be done only through FileManager. This is useful in general since file operations will be abstracted in the future for the reproduction mechanism. FileSystemOptions is independent of FileManager so that we can have multiple translation units sharing the same FileManager but with different FileSystemOptions.

When saving a preamble, create a buffer larger than the actual file we're working with but fill everything from the end of the preamble to the end of the file with spaces (so the lexer will quickly skip them).

Revamp the SourceManager to separate the representation of parsed source locations from source locations loaded from an AST/PCH file. Previously, loading an AST/PCH file involved carefully pre-allocating space at the beginning of the source manager for the source locations and FileIDs that correspond to the prefix, and then appending the source locations/FileIDs used for parsing the remaining translation unit. This design forced us into loading PCH files early, as a prefix, whic has become a rather significant limitation. This patch splits the SourceManager space into two parts: for source location "addresses", the lower values (growing upward) are used to describe parsed code, while upper values (growing downward) are used for source locations loaded from AST/PCH files. Similarly, positive FileIDs are used to describe parsed code while negative FileIDs are used to file/macro locations loaded from AST/PCH files. As a result, we can load PCH/AST files even during parsing, making various improvemnts in the future possible, e.g., teaching #include <foo.h> to look for and load <foo.h.gch> if it happens to be already available. This patch was originally written by Sebastian Redl, then brought forward to the modern age by Jonathan Turner, and finally polished/finished by me to be committed. llvm-svn: 135484

Fix three related, wily issues with the recompilation of precompiled 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. llvm-svn: 116041

Introduce basic support for loading a precompiled preamble while reparsing an ASTUnit. When saving a preamble, create a buffer larger than the actual file we're working with but fill everything from the end of the preamble to the end of the file with spaces (so the lexer will quickly skip them). When we load the file, create a buffer of the same size, filling it with the file and then spaces. Then, instruct the lexer to start lexing after the preamble, therefore continuing the parse from the spot where the preamble left off. It's now possible to perform a simple preamble build + parse (+ reparse) with ASTUnit. However, one has to disable a bunch of checking in the PCH reader to do so. That part isn't committed; it will likely be handled with some other kind of flag (e.g., -fno-validate-pch). As part of this, fix some issues with null termination of the memory buffers created for the preamble; we were trying to explicitly NULL-terminate them, even though they were also getting implicitly NULL terminated, leading to excess warnings about NULL characters in source files. llvm-svn: 109445

Fix three related, wily issues with the recompilation of precompiled 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. llvm-svn: 116041

Revamp the SourceManager to separate the representation of parsed source locations from source locations loaded from an AST/PCH file. Previously, loading an AST/PCH file involved carefully pre-allocating space at the beginning of the source manager for the source locations and FileIDs that correspond to the prefix, and then appending the source locations/FileIDs used for parsing the remaining translation unit. This design forced us into loading PCH files early, as a prefix, whic has become a rather significant limitation. This patch splits the SourceManager space into two parts: for source location "addresses", the lower values (growing upward) are used to describe parsed code, while upper values (growing downward) are used for source locations loaded from AST/PCH files. Similarly, positive FileIDs are used to describe parsed code while negative FileIDs are used to file/macro locations loaded from AST/PCH files. As a result, we can load PCH/AST files even during parsing, making various improvemnts in the future possible, e.g., teaching #include <foo.h> to look for and load <foo.h.gch> if it happens to be already available. This patch was originally written by Sebastian Redl, then brought forward to the modern age by Jonathan Turner, and finally polished/finished by me to be committed. llvm-svn: 135484

Implement caching of code-completion results for macro definitions when the CXTranslationUnit_CacheCompletionResults option is given to clang_parseTranslationUnit(). Essentially, we compute code-completion results for macro definitions after we have parsed the file, then store an ASTContext-agnostic version of those results (completion string, cursor kind, priority, and active contexts) in the ASTUnit. When performing code completion in that ASTUnit, we splice the macro definition results into the results provided by the actual code-completion (which has had macros turned off) before libclang gets those results. We use completion context information to only splice in those results that make sense for that context. With a completion involving all of the macros from Cocoa.h and a few other system libraries (totally ~8500 macro definitions) living in a precompiled header, we get about a 9% performance improvement from code completion, since we no longer have to deserialize all of the macro definitions from the precompiled header. Note that macro definitions are merely the canary; the cache is designed to also support other top-level declarations, which should be a bigger performance win. That optimization will be next. Note also that there is no mechanism for determining when to throw away the cache and recompute its contents. llvm-svn: 111051

Rework how CIndex handles diagnostics. Rather than using a callback, we attach diagnostics to translation units and code-completion results, so they can be queried at any time. To facilitate this, the new StoredDiagnostic class stores a diagnostic in a serializable/deserializable form, and ASTUnit knows how to capture diagnostics in this stored form. CIndex's CXDiagnostic is a thin wrapper around StoredDiagnostic, providing a C interface to stored or de-serialized diagnostics. I've XFAIL'd one test case temporarily, because currently we end up storing diagnostics in an ASTUnit that's never returned to the user (because it contains errors). I'll introduce a temporary fix for this soon; the real fix will be to allow us to return and query invalid ASTs. llvm-svn: 96592

Introduce a flag in SourceManager to treat non-system source files as "volatile", meaning there's a high enough chance that they may change while we are trying to use them. This flag is only enabled by libclang. Currently "volatile" source files will be stat'ed immediately before opening them, because the file size stat info may not be accurate since when we got it (e.g. from the PCH). This avoids crashes when trying to reference mmap'ed memory from a file whose size is not what we expect. Note that there's still a window for a racing issue to occur but the window for it should be way smaller than before. We can consider later on to avoid mmap completely on such files. rdar://11612916 llvm-svn: 160074

Revamp the SourceManager to separate the representation of parsed source locations from source locations loaded from an AST/PCH file. Previously, loading an AST/PCH file involved carefully pre-allocating space at the beginning of the source manager for the source locations and FileIDs that correspond to the prefix, and then appending the source locations/FileIDs used for parsing the remaining translation unit. This design forced us into loading PCH files early, as a prefix, whic has become a rather significant limitation. This patch splits the SourceManager space into two parts: for source location "addresses", the lower values (growing upward) are used to describe parsed code, while upper values (growing downward) are used for source locations loaded from AST/PCH files. Similarly, positive FileIDs are used to describe parsed code while negative FileIDs are used to file/macro locations loaded from AST/PCH files. As a result, we can load PCH/AST files even during parsing, making various improvemnts in the future possible, e.g., teaching #include <foo.h> to look for and load <foo.h.gch> if it happens to be already available. This patch was originally written by Sebastian Redl, then brought forward to the modern age by Jonathan Turner, and finally polished/finished by me to be committed. llvm-svn: 135484

When we try (but fail) to build a precompiled preamble, wait for a short "cooling off" period (defaulting to 5 reparses) before trying to build a precompiled preamble again. Previously, if we failed to build the precompiled preamble at any time, we just gave up the whole charade any never tried again. llvm-svn: 110187

Add code-completion support directly to ASTUnit, which performs code completion within the translation unit using the same command-line arguments for parsing the translation unit. Eventually, we'll reuse the precompiled preamble to improve code-completion performance, and this also gives us a place to cache results. Expose this function via the new libclang function clang_codeCompleteAt(), which performs the code completion within a CXTranslationUnit. The completion occurs in-process (clang_codeCompletion() runs code completion out-of-process). llvm-svn: 110210

Implement caching of code-completion results for macro definitions when the CXTranslationUnit_CacheCompletionResults option is given to clang_parseTranslationUnit(). Essentially, we compute code-completion results for macro definitions after we have parsed the file, then store an ASTContext-agnostic version of those results (completion string, cursor kind, priority, and active contexts) in the ASTUnit. When performing code completion in that ASTUnit, we splice the macro definition results into the results provided by the actual code-completion (which has had macros turned off) before libclang gets those results. We use completion context information to only splice in those results that make sense for that context. With a completion involving all of the macros from Cocoa.h and a few other system libraries (totally ~8500 macro definitions) living in a precompiled header, we get about a 9% performance improvement from code completion, since we no longer have to deserialize all of the macro definitions from the precompiled header. Note that macro definitions are merely the canary; the cache is designed to also support other top-level declarations, which should be a bigger performance win. That optimization will be next. Note also that there is no mechanism for determining when to throw away the cache and recompute its contents. llvm-svn: 111051

A new code completion option that enables including brief comments into CodeCompletionString should be a, err, code completion option.

[code-complete] Introduce CodeCompletionTUInfo which will be used for caching code-completion related strings specific to a translation unit (ASTContext and related data) CodeCompletionAllocator does such limited caching, by caching the name assigned to a DeclContext*, but that is not the appropriate place since that object has a lifetime that can extend beyond that of an ASTContext. Introduce CodeCompletionTUInfo which will be always tied to a translation unit to do this kind of caching and move the caching of CodeCompletionAllocator into this object, and propagate it to all the places where it will be needed. The plan is to extend the caching where appropriate, using CodeCompletionTUInfo, to avoid re-calculating code-completion strings. Part of rdar://10796159. llvm-svn: 154408

Make 'LangOptions' in CompilerInvocation a heap-allocated, reference counted object. I discovered that llvm::RefCountedBase<T> has a bug where the reference count is copied in the copy constructor, which means that there were cases when the CompilerInvocation objects created by ASTUnit were actually leaked. When I fixed that bug locally, it showed that a whole bunch of code assumed that the LangOptions object that was part of CompilerInvocation was still alive. By making it heap-allocated and reference counted, we can keep it around after the CompilerInvocation object goes away. As part of this change, change CompilerInvocation:getLangOptions() to return a pointer, acting as another clue that this object may outlive the CompilerInvocation object. This commit doesn't fix the CompilerInvocation leak itself. That will come when I commit the fix to llvm::RefCountedBase<T> to mainline LLVM. llvm-svn: 144930

Implement caching of code-completion results for macro definitions when the CXTranslationUnit_CacheCompletionResults option is given to clang_parseTranslationUnit(). Essentially, we compute code-completion results for macro definitions after we have parsed the file, then store an ASTContext-agnostic version of those results (completion string, cursor kind, priority, and active contexts) in the ASTUnit. When performing code completion in that ASTUnit, we splice the macro definition results into the results provided by the actual code-completion (which has had macros turned off) before libclang gets those results. We use completion context information to only splice in those results that make sense for that context. With a completion involving all of the macros from Cocoa.h and a few other system libraries (totally ~8500 macro definitions) living in a precompiled header, we get about a 9% performance improvement from code completion, since we no longer have to deserialize all of the macro definitions from the precompiled header. Note that macro definitions are merely the canary; the cache is designed to also support other top-level declarations, which should be a bigger performance win. That optimization will be next. Note also that there is no mechanism for determining when to throw away the cache and recompute its contents. llvm-svn: 111051

But because ASTUnit caches global declarations during parsing before even completion consumer is created, the option is duplicated as a translation unit option (in both libclang and ASTUnit, like the option to cache code completion results). llvm-svn: 159539

Improve our uniquing of file entries when files are re-saved or are overridden via remapping. Thus, when we create a "virtual" file in the file manager, we still stat() the real file that lives behind it so that we can provide proper uniquing based on inodes. This helps keep the file manager much more consistent. To take advantage of this when reparsing files in libclang, we disable the use of the stat() cache when reparsing or performing code completion, since the stat() cache is very likely to be out of date in this use case. llvm-svn: 124971

Revamp the SourceManager to separate the representation of parsed source locations from source locations loaded from an AST/PCH file. Previously, loading an AST/PCH file involved carefully pre-allocating space at the beginning of the source manager for the source locations and FileIDs that correspond to the prefix, and then appending the source locations/FileIDs used for parsing the remaining translation unit. This design forced us into loading PCH files early, as a prefix, whic has become a rather significant limitation. This patch splits the SourceManager space into two parts: for source location "addresses", the lower values (growing upward) are used to describe parsed code, while upper values (growing downward) are used for source locations loaded from AST/PCH files. Similarly, positive FileIDs are used to describe parsed code while negative FileIDs are used to file/macro locations loaded from AST/PCH files. As a result, we can load PCH/AST files even during parsing, making various improvemnts in the future possible, e.g., teaching #include <foo.h> to look for and load <foo.h.gch> if it happens to be already available.

Revamp the SourceManager to separate the representation of parsed source locations from source locations loaded from an AST/PCH file. Previously, loading an AST/PCH file involved carefully pre-allocating space at the beginning of the source manager for the source locations and FileIDs that correspond to the prefix, and then appending the source locations/FileIDs used for parsing the remaining translation unit. This design forced us into loading PCH files early, as a prefix, whic has become a rather significant limitation. This patch splits the SourceManager space into two parts: for source location "addresses", the lower values (growing upward) are used to describe parsed code, while upper values (growing downward) are used for source locations loaded from AST/PCH files. Similarly, positive FileIDs are used to describe parsed code while negative FileIDs are used to file/macro locations loaded from AST/PCH files. As a result, we can load PCH/AST files even during parsing, making various improvemnts in the future possible, e.g., teaching #include <foo.h> to look for and load <foo.h.gch> if it happens to be already available.

Don't map a file:line:col triplet that is inside the preamble range to a "loaded" location of the precompiled preamble. Instead, handle specially locations of preprocessed entities: -When looking up for preprocessed entities, map main file locations inside the preamble range to a preamble loaded location. -When getting the source range of a preprocessing cursor, map preamble loaded locations back to main file locations.

[PCH] When visiting preprocessed entities, make it possible to avoid deserializing preprocessed entities that are #included in the range that we are interested. This is useful when we are interested in preprocessed entities of a specific file, e.g when we are annotating tokens. There is also an optimization where we cache the last result of PreprocessingRecord::getPreprocessedEntitiesInRange and we re-use it if there is a call with the same range as before. rdar://10313365 llvm-svn: 142887
