enum llvm::X86::RelocationType

RelocationType - An enum for the x86 relocation codes. Note that the terminology here doesn't follow x86 convention - word means 32-bit and dword means 64-bit. The relocations will be treated by JIT or ObjectCode emitters, this is transparent to the x86 code emitter but JIT and ObjectCode will treat them differently

Enumerator
reloc_pcrel_word	reloc_pcrel_word - PC relative relocation, add the relocated value to the value already in memory, after we adjust it for where the PC is.
reloc_picrel_word	reloc_picrel_word - PIC base relative relocation, add the relocated value to the value already in memory, after we adjust it for where the PIC base is.
reloc_absolute_word	reloc_absolute_word - absolute relocation, just add the relocated value to the value already in memory.
reloc_absolute_word_sext	reloc_absolute_word_sext - absolute relocation, just add the relocated value to the value already in memory. In object files, it represents a value which must be sign-extended when resolving the relocation.
reloc_absolute_dword	reloc_absolute_dword - absolute relocation, just add the relocated value to the value already in memory.
