// MipsOptionRecord - Abstraction for storing arbitrary information in
|
|
// ELF files. Arbitrary information (e.g. register usage) can be stored in Mips
|
|
// specific ELF sections like .Mips.options. Specific records should subclass
|
|
// MipsOptionRecord and provide an implementation to EmitMipsOptionRecord which
|
|
// basically just dumps the information into an ELF section. More information
|
|
// about .Mips.option can be found in the SysV ABI and the 64-bit ELF Object
|
|
// specification.
