◆ isPICDefault()

bool clang::driver::toolchains::AMDGPUToolChain::isPICDefault ( ) const

◆ isPICDefaultForced()

bool clang::driver::toolchains::AMDGPUToolChain::isPICDefaultForced ( ) const

inlineoverridevirtual

Tests whether this toolchain forces its default for PIC, PIE or non-PIC.

If this returns true, any PIC related flags should be ignored and instead the results of isPICDefault() and isPIEDefault(const llvm::opt::ArgList &Args) are used exclusively.

Implements clang::driver::ToolChain.

overridevirtual

TranslateArgs - Create a new derived argument list for any argument translations this ToolChain may wish to perform, or 0 if no tool chain specific translations are needed.

If DeviceOffloadKind is specified the translation specific for that offload kind is performed.

Parameters

BoundArch	- The bound architecture name, or 0.
DeviceOffloadKind	- The device offload kind used for the translation.
