* revert SVN r265702, r265640Saleem Abdulrasool2016-04-081-8/+4
| | | | | | | | | | | Revert the two changes to thread CodeGenOptions into the TargetInfo allocation and to fix the layering violation by moving CodeGenOptions into Basic. Code Generation is arguably not particularly "basic". This addresses Richard's post-commit review comments. This change purely does the mechanical revert and will be followed up with an alternate approach to thread the desired information into TargetInfo. llvm-svn: 265806
* Basic: thread CodeGenOptions into TargetInfoSaleem Abdulrasool2016-04-071-4/+8
| | | | | | | | | This threads CodeGenOptions into the TargetInfo hierarchy. This is motivated by ARM which can change some target information based on the EABI selected (-meabi). Similar options exist for other platforms (e.g. MIPS) and thus is generally useful. NFC. llvm-svn: 265640

| | | | | | | | | | | | option. Previously these options could both be used to specify that you were compiling the implementation file of a module, with a different set of minor bugs in each case. This change removes -fmodule-implementation-of, and instead tracks a flag to determine whether we're currently building a module. -fmodule-name now behaves the same way that -fmodule-implementation-of previously did. llvm-svn: 261372

* [libclang] Add a flag to create the precompiled preamble on the first parse.Benjamin Kramer2015-12-151-16/+19
| | | | | | | | | | | | | | | | | | | | | Summary: The current default is to create the preamble on the first reparse, aka second parse. This is useful for clients that do not want to block when opening a file because serializing the preamble takes a bit of time. However, this makes the reparse much more expensive and that may be on the critical path as it's the first interaction a user has with the source code. YouCompleteMe currently optimizes for the first code interaction by parsing the file twice when loaded. That's just unnecessarily slow and this flag helps to avoid that.

* Introduce module file extensions to piggy-back data onto module files.Douglas Gregor2015-11-031-3/+4
| | | | | | | | | | | | | | | | | | | | | Introduce the notion of a module file extension, which introduces additional information into a module file at the time it is built that can then be queried when the module file is read. Module file extensions are identified by a block name (which must be unique to the extension) and can write any bitstream records into their own extension block within the module file. When a module file is loaded, any extension blocks are matched up with module file extension readers, that are per-module-file and are given access to the input bitstream. Note that module file extensions can only be introduced by programmatic clients that have access to the CompilerInvocation. There is only one such extension at the moment, which is used for testing the module file extension harness. As a future direction, one could imagine allowing the plugin mechanism to introduce new module file extensions. llvm-svn: 251955

The driver expands -gmodules to "-g -fmodule-format=obj -dwarf-ext-refs" and passes that to cc1. All this does at the moment is set a flag codegenopts. http://reviews.llvm.org/D11958 llvm-svn: 246192

| | | | | | | | | | | | | - introduces a new cc1 option -fmodule-format=[raw,obj] with 'raw' being the default - supports arbitrary module container formats that libclang is agnostic to - adds the format to the module hash to avoid collisions - splits the old PCHContainerOperations into PCHContainerWriter and a PCHContainerReader.

* Introduce a PCHContainerOperations interface (NFC).Adrian Prantl2015-06-201-42/+67
| | | | | | | | | | | | | | | | A PCHContainerOperations abstract interface provides operations for creating and unwrapping containers for serialized ASTs (precompiled headers and clang modules). The default implementation is RawPCHContainerOperations, which uses a flat file for the output. The main application for this interface will be an ObjectFilePCHContainerOperations implementation that uses LLVM to wrap the module in an ELF/Mach-O/COFF container to store debug info alongside the AST. rdar://problem/20091852 llvm-svn: 240225

Call sites were found with the ASTMatcher + some semi-automated cleanup. memberCallExpr( argumentCountIs(1), callee(methodDecl(hasName("push_back"))), on(hasType(recordDecl(has(namedDecl(hasName("emplace_back")))))), hasArgument(0, bindTemporaryExpr( hasType(recordDecl(hasNonTrivialDestructor())), has(constructExpr()))), unless(isInTemplateInstantiation())) No functional change intended. llvm-svn: 238601

* Remove many superfluous SmallString::str() calls.Yaron Keren2015-03-181-3/+3
| | | | | | | | | | | | | | | Now that SmallString is a first-class citizen, most SmallString::str() calls are not required. This patch removes a whole bunch of them, yet there are lots more. There are two use cases where str() is really needed: 1) To use one of StringRef member functions which is not available in SmallString. 2) To convert to std::string, as StringRef implicitly converts while SmallString do not. We may wish to change this, but it may introduce ambiguity. llvm-svn: 232622
* [modules] Teach the AST reader to handle the case of importing a moduleChandler Carruth2015-03-141-2/+2

While we can't check that the CPU name used to build the module will end up being able to codegen correctly for the translation unit, we actually check that the imported features are a subset of the existing features. While here, rewrite the code to use std::set_difference and have it diagnose all of the differences found. Test case added which walks the set relationships and ensures we diagnose all the right cases and accept the others. No functional change for implicit modules here, just better diagnostics. llvm-svn: 232248

| | | | | | | | | | | | | | | | | This is a necessary prerequisite for debugging with modules.

* [modules] Initial support for explicitly loading .pcm files.Richard Smith2014-10-221-1/+2
| | | | | | | | | | | | | | | Implicit module builds are not well-suited to a lot of build systems. In particular, they fare badly in distributed build systems, and they lead to build artifacts that are not tracked as part of the usual dependency management process. This change allows explicitly-built module files (which are already supported through the -emit-module flag) to be explicitly loaded into a build, allowing build systems to opt to manage module builds and dependencies themselves. This is only the first step in supporting such configurations, and it should be considered experimental and subject to change or removal for now. llvm-svn: 220359
* Frontend: Don't accept null DiagnosticsEngines when building ASTUnitsJustin Bogner2014-10-151-17/+4
| | | | | | | | | | | | | The various ways to create an ASTUnit all take a refcounted pointer to a diagnostics engine as an argument, and if it isn't pointing at anything they initialize it. This is a pretty confusing API, and it really makes more sense for the caller to initialize the thing since they control the lifetime anyway. This fixes the one caller that didn't bother initializing the pointer and asserts that the argument is initialized. llvm-svn: 219752

| | | | | | | | | | | | | | Rather than having a pair of pairs and a reference out parameter, build a structure with everything together and named. A raw pointer and a unique_ptr, rather than a raw pointer and a boolean, are used to communicate ownership transfer. It's possible one day we'll end up with a conditional pointer (probably represented by a raw pointer and a boolean) abstraction to use in places like this. Conditional ownership seems to be coming up more often than I'd hoped... llvm-svn: 216712
