Currently we report errors as "unrecognized opcode `fence.i'" when the opcode isn't part of the selected extensions. This patch expands that error message to include the missing extension information. For example, now the error message would be "unrecognized opcode `fence.i', extension `zifencei' required". If the opcode is not a part of any extension, the error message reverts to "unrecognized opcode `<op statement>'". Signed-off-by: Patrick O'Neill <patrick@rivosinc.com> bfd/ pr 28733 * elfxx-riscv.c (riscv_multi_subset_supports_ext): New function, used to return the extension string for each INSN_CLASS_*. * elfxx-riscv.h: Added extern riscv_multi_subset_supports_ext. gas/ pr 28733 * config/tc-riscv.c (struct riscv_ip_error): New structure, contains information about errors that occur within the riscv_ip. (riscv_ip): Use struct riscv_ip_error to report more detailed errors. * testsuite/gas/riscv/c-fld-fsd-fail.l: Updated. * testsuite/gas/riscv/march-imply-i2p1-01.: Likewise.
