◆ createBlockSymbol()

Get or create a symbol for a basic block.

For non-always-emit symbols, this behaves like createTempSymbol, except that it uses the PrivateLabelPrefix instead of the PrivateGlobalPrefix. When AlwaysEmit is true, behaves like getOrCreateSymbol, prefixed with PrivateLabelPrefix.

◆ setCompilationDir()

void llvm::MCContext::setCompilationDir ( StringRef S) inline

◆ setCurrentDwarfLoc()

Saves the information from the currently parsed dwarf .loc directive and sets DwarfLocSeen.

When the next instruction is assembled an entry in the line number table with this information and the address of the instruction will be created.
