◆ GetTriplePlusArchString()

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

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.

StringRef  BaseName,
types::ID  FileType

static

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