PowerPC TLS Dynamic Call Fixup
Context object for machine code objects.
virtual unsigned getRelocType(MCContext &Ctx, const MCValue &Target, const MCFixup &Fixup, bool IsPCRel) const =0
Encode information on a single operation to perform on a byte sequence (e.g., an encoded instruction)...
This represents an "assembler immediate".
StringRef - Represent a constant reference to a string, i.e.
Target - Wrapper for Target specific information.
@ C
The default llvm calling convention, compatible with C.
