Detailed Description

This is a class to find a viable GCC installation for Clang to use.

This class tries to find a GCC installation on the system, and report information about it. It starts from the host information provided to the Driver, and has logic for fuzzing that where appropriate.

◆ getBiarchSibling()

bool Generic_GCC::GCCInstallationDetector::getBiarchSibling ( Multilib M) const

Get the biarch sibling multilib (if it exists).

true iff such a sibling exists

◆ getTriple()

◆ getVersion()

◆ init()

void Generic_GCC::GCCInstallationDetector::init ( const llvm::Triple &  TargetTriple,
const llvm::opt::ArgList &  Args 

Initialize a GCCInstallationDetector from the driver.

This performs all of the autodetection and sets up the various paths. Once constructed, a GCCInstallationDetector is essentially immutable.

FIXME: We shouldn't need an explicit TargetTriple parameter here, and should instead pull the target out of the driver. This is currently necessary because the driver doesn't store the final version of the target triple.
