Nelson Chu c2137f55ad RISC-V: Add sext.[bh] and zext.[bhw] pseudo instructions. ... https://github.com/riscv/riscv-asm-manual/pull/61 We aleady have sext.w, so just add sext.b, sext.h, zext.b, zext.h and zext.w. In a certain sense, zext.b is not a pseudo - It is an alias of andi. Similarly, sext.b and sext.h are aliases of other rvb instructions, when we enable b extension; But they are pseudos when we just enable rvi. However, this patch does not consider the rvb cases. Besides, zext.w is only valid in rv64. gas/ * config/tc-riscv.c (riscv_ext): New function. Use md_assemblef to expand the zext and sext pseudos, to give them a chance to be expanded into c-ext instructions. (macro): Handle M_ZEXTH, M_ZEXTW, M_SEXTB and M_SEXTH. * testsuite/gas/riscv/ext.s: New testcase. * testsuite/gas/riscv/ext-32.d: Likewise. * testsuite/gas/riscv/ext-64.d: Likewise. include/ * opcode/riscv.h (M_ZEXTH, M_ZEXTW, M_SEXTB, M_SEXTH.): Added. opcodes/ * riscv-opc.c (riscv_opcodes): Add sext.[bh] and zext.[bhw].		2020-12-10 10:50:44 +08:00
