Enumeration Type Documentation

◆ Libcall

enum llvm::RTLIB::Libcall

RTLIB::Libcall enum - This enum defines all of the runtime library calls the backend can emit.

The various long double types cannot be merged, because 80-bit library functions use "xf" and 128-bit use "tf".

When adding PPCF128 functions here, note that their names generally need to be overridden for Darwin with the xxx$LDBL128 form. See PPCISelLowering.cpp.
