Function Documentation

◆ computeTargetTriple()

static llvm::Triple computeTargetTriple ( const Driver D,
StringRef  TargetTriple,
const ArgList &  Args,
StringRef  DarwinArchName = "" 

Compute target triple from args.

This routine provides the logic to compute a target triple from various args passed to the driver and the default triple string.

◆ ContainsCompileOrAssembleAction()

static bool ContainsCompileOrAssembleAction ( const Action A)

Check whether the given input tree contains any compilation or assembly actions.

◆ DiagnoseInputExistence()

static bool DiagnoseInputExistence ( const Driver D,
const DerivedArgList &  Args,
StringRef  Value,
types::ID  Ty 

Check that the file referenced by Value exists.

If it doesn't, issue a diagnostic and return false.

◆ GetTriplePlusArchString()

static std::string GetTriplePlusArchString ( const ToolChain TC,
StringRef  BoundArch,
Action::OffloadKind  OffloadKind 

Return a string that uniquely identifies the result of a job.

The bound arch is not necessarily represented in the toolchain's triple – for example, armv7 and armv7s both map to the same triple – so we need both in our map. Also, we need to add the offloading device kind, as the same tool chain can be used for host and device for some programming models, e.g. OpenMP.

◆ MakeCLOutputFilename()

static const char* MakeCLOutputFilename ( const ArgList &  Args,
StringRef  ArgValue,
StringRef  BaseName,
types::ID  FileType 

Create output filename based on ArgValue, which could either be a full filename, filename without extension, or a directory.

If ArgValue does not provide a filename, then use BaseName, and use the extension suitable for FileType.

◆ searchForFile()

static bool searchForFile ( SmallVectorImpl< char > &  FilePath,
ArrayRef< std::string >  Dirs,
StringRef  FileName 

Looks the given directories for the specified file.

[out]FilePathFile path, if the file was found.
[in]DirsDirectories used for the search.
[in]FileNameName of the file to search for.
True if file was found.

Looks for file specified by FileName sequentially in directories specified by Dirs.
