Function Documentation

◆ collectTOCStats()

static void collectTOCStats ( PPCAsmPrinter::TOCEntryType  Type)
static

Definition at line 450 of file PPCAsmPrinter.cpp.

◆ convertToSinitPriority()

static std::string convertToSinitPriority ( int  Priority)
static

◆ createMCSymbolForTlsGetAddr()

static MCSymbol * createMCSymbolForTlsGetAddr ( MCContext Ctx,
unsigned  MIOpc 
)
static

This helper function creates the TlsGetAddr/TlsGetMod MCSymbol for AIX.

We will create the csect and use the qual-name symbol instead of creating just the external symbol.
