This is a update to D43157 to correctly handle fixup_riscv_pcrel_lo12. Notable changes: Rebased onto trunk Handle and test S-type Test case pcrel-hilo.s is merged into relocations.s D43157 description: VK_RISCV_PCREL_LO has to be handled specially. The MCExpr inside is actually the location of an auipc instruction with a VK_RISCV_PCREL_HI fixup pointing to the real target. Differential Revision: https://reviews.llvm.org/D54029 Patch by Chih-Mao Chen and Michael Spencer. llvm-svn: 349764
