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.

Member Function Documentation

getBiarchSibling()

bool Generic_GCC::GCCInstallationDetector::getBiarchSibling

(

Multilib &

M

)

const

Get the biarch sibling multilib (if it exists).

Returns

true iff such a sibling exists

getInstallPath()

StringRef clang::driver::toolchains::Generic_GCC::GCCInstallationDetector::getInstallPath ( ) const

inline

Get the detected GCC installation path.

Definition at line 279 of file Gnu.h.

getMultilib()

const Multilib & clang::driver::toolchains::Generic_GCC::GCCInstallationDetector::getMultilib ( ) const

inline

Get the detected Multilib.

Definition at line 289 of file Gnu.h.

getMultilibs()

const MultilibSet & clang::driver::toolchains::Generic_GCC::GCCInstallationDetector::getMultilibs ( ) const

inline

Get the whole MultilibSet.

Definition at line 294 of file Gnu.h.

getParentLibPath()

StringRef clang::driver::toolchains::Generic_GCC::GCCInstallationDetector::getParentLibPath ( ) const

inline

Get the detected GCC parent lib path.

Definition at line 284 of file Gnu.h.

getSelectedInstallation()

const GCCInstallCandidate & clang::driver::toolchains::Generic_GCC::GCCInstallationDetector::getSelectedInstallation ( ) const

inline

Definition at line 269 of file Gnu.h.

getTriple()

const llvm::Triple & clang::driver::toolchains::Generic_GCC::GCCInstallationDetector::getTriple ( ) const

inline

Get the GCC triple for the detected install.

Definition at line 274 of file Gnu.h.

getVersion()

const GCCVersion & clang::driver::toolchains::Generic_GCC::GCCInstallationDetector::getVersion ( ) const

inline

Get the detected GCC version string.

Definition at line 301 of file Gnu.h.

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.

isValid()

bool clang::driver::toolchains::Generic_GCC::GCCInstallationDetector::isValid ( ) const

inline

Check whether we detected a valid GCC install.

Definition at line 267 of file Gnu.h.

print()

void Generic_GCC::GCCInstallationDetector::print

(

raw_ostream &

OS

)

const

Print information about the detected GCC installation.

Member Data Documentation

TripleToDebianMultiarch

std::function<StringRef(const llvm::Triple &)> clang::driver::toolchains::Generic_GCC::GCCInstallationDetector::TripleToDebianMultiarch

Initial value:

=
        [](const llvm::Triple &T) {
          StringRef S = T.str();
          return S;
        }

Function for converting a triple to a Debian multiarch.

The toolchains use this to adjust the target specific component of include paths for Debian.
