; These test cases are to ensure that when using pc relative memory operations
; ABI correct code and relocations are produced for Initial Exec TLS Model.
; Note that with R_PPC64_TLS relocations, to distinguish PC relative
; TLS the relocation has a field value displaced by one byte from the
; beginning of the instruction.
