Member Function Documentation

◆ createFromSubtargetFeatures()

TargetID TargetID::createFromSubtargetFeatures ( const Triple & TT,
StringRef CPU,
StringRef FeatureString )
static

Construct a TargetID for triple TT and processor CPU, taking the xnack/sramecc modes from the subtarget FeatureString (a comma-separated "+xnack,-sramecc" list).

Unspecified modes keep the processor's default. The assembler uses this because it has no target directive to carry the mode.
