Three-part patch set from Tsukasa OI to support zmmul in assembler. The 'Zmmul' is a RISC-V extension consisting of only multiply instructions (a subset of 'M' which has multiply and divide instructions). bfd/ * elfxx-riscv.c (riscv_implicit_subsets): Add 'Zmmul' implied by 'M'. (riscv_supported_std_z_ext): Add 'Zmmul' extension. (riscv_multi_subset_supports): Add handling for new instruction class. gas/ * testsuite/gas/riscv/attribute-09.d: Updated implicit 'Zmmul' by 'M'. * testsuite/gas/riscv/option-arch-02.d: Likewise. * testsuite/gas/riscv/m-ext.s: New test. * testsuite/gas/riscv/m-ext-32.d: New test (RV32). * testsuite/gas/riscv/m-ext-64.d: New test (RV64). * testsuite/gas/riscv/zmmul-32.d: New expected output. * testsuite/gas/riscv/zmmul-64.d: Likewise. * testsuite/gas/riscv/m-ext-fail-xlen-32.d: New test (failure by using RV64-only instructions in RV32). * testsuite/gas/riscv/m-ext-fail-xlen-32.l: Likewise. * testsuite/gas/riscv/m-ext-fail-zmmul-32.d: New failure test (RV32 + Zmmul but with no M). * testsuite/gas/riscv/m-ext-fail-zmmul-32.l: Likewise. * testsuite/gas/riscv/m-ext-fail-zmmul-64.d: New failure test (RV64 + Zmmul but with no M). * testsuite/gas/riscv/m-ext-fail-zmmul-64.l: Likewise. * testsuite/gas/riscv/m-ext-fail-noarch-64.d: New failure test (no Zmmul or M). * testsuite/gas/riscv/m-ext-fail-noarch-64.l: Likewise. include/ * opcode/riscv.h (enum riscv_insn_class): Added INSN_CLASS_ZMMUL. ld/ * testsuite/ld-riscv-elf/attr-merge-arch-01.d: We don't care zmmul in these testcases, so just replaced m by a. * testsuite/ld-riscv-elf/attr-merge-arch-01a.s: Likewise. * testsuite/ld-riscv-elf/attr-merge-arch-01b.s: Likewise. * testsuite/ld-riscv-elf/attr-merge-arch-02.d: Likewise. * testsuite/ld-riscv-elf/attr-merge-arch-02a.s: Likewise. * testsuite/ld-riscv-elf/attr-merge-arch-03.d: Likewise. * testsuite/ld-riscv-elf/attr-merge-arch-03a.s: Likewise. * testsuite/ld-riscv-elf/attr-merge-user-ext-01.d: Likewise. * testsuite/ld-riscv-elf/attr-merge-user-ext-rv32i2p1_a2p0.s: Renamed. * testsuite/ld-riscv-elf/attr-merge-user-ext-rv32i2p1_a2p1.s: Renamed. opcodes/ * riscv-opc.c (riscv_opcodes): Updated multiply instructions to zmmul. |
