R_TRL	TOC relative indirect load relocation. Similar to R_TOC, but not modifiable instruction.
R_TRLA	Relative to the TOC or to the thread-local storage base relocation. Compilers are not permitted to generate this relocation type. It is the result of a reversible transformation by the linker of an R_TOC relation that turned a load instruction into an add-immediate instruction.
R_GL	Global linkage-external TOC address relocation. Provides the address of the external TOC associated with a defined external symbol.
R_TCL	Local object TOC address relocation. Provides the address of the local TOC entry of a defined external symbol.
R_REF	A non-relocating relocation. Used to prevent the binder from garbage collecting a csect (such as code used for dynamic initialization of non-local statics) for which another csect has an implicit dependency.
R_BA	Branch absolute relocation. Provides the address of the referenced symbol. References a non-modifiable instruction.
R_BR	Branch relative to self relocation. Provides the displacement that is the difference between the address of the referenced symbol and the address of the referenced branch instruction. References a non-modifiable instruction.
R_RBA	Branch absolute relocation. Similar to R_BA but references a modifiable instruction.
R_RBR	Branch relative to self relocation. Similar to the R_BR relocation type, but references a modifiable instruction.
R_TLS	General-dynamic reference to TLS symbol.
R_TLS_IE	Initial-exec reference to TLS symbol.
R_TLS_LD	Local-dynamic reference to TLS symbol.
R_TLS_LE	Local-exec reference to TLS symbol.
R_TLSM	Module reference to TLS. Provides a handle for the module containing the referenced symbol.
R_TLSML	Module reference to the local TLS storage.
R_TOCU	Relative to TOC upper. Specifies the high-order 16 bits of a large code model TOC-relative relocation.
R_TOCL	Relative to TOC lower. Specifies the low-order 16 bits of a large code model TOC-relative relocation.
