[llvm-dev] ELF relocations

[Hassan ELMADI via llvm-dev]

Hi,
In the include/llvm/Support/ELFRelocs directory, there is a bunch of .def files defining enums that are to be included in ELF.h. For example, in ARM.def, there is this record:

ELF_RELOC(R_ARM_PC24,                   0x01)

What does 'R_ARM_PC24' mean and where does the value 0x01 come from?
I'm trying to define a backend for a custom cpu and I have to provide a .def file but I don't know what these records mean.
Best,

Hassan Elmadi
