Bug ID: 22179
Summary: [RISCV] fmv.w.x and fmv.x.w opcodes are not recognised
Product: binutils
Version: 2.30 (HEAD)
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: gas
Assignee: unassigned at sourceware dot org
Reporter: asb at lowrisc dot org
Target Milestone: ---
The RISC-V 2.2 user-level ISA specification renamed fmv.s.x and fmv.x.s to
fmv.w.x and fmv.x.w respectively. gas doesn't recognise these mnemonics.
Additionally, objdump should probably prefer to print the new names in
preference to the old.
$ cat f.s
fmv.x.w a2, fs7
fmv.x.s a2, fs7
fmv.w.x ft1, a6
fmv.s.x ft1, a6
$ ./riscv32-unknown-elf-as -march=rv32if f.s
f.s: Assembler messages:
f.s:1: Error: unrecognized opcode `fmv.x.w a2,fs7'
f.s:3: Error: unrecognized opcode `fmv.w.x ft1,a6'
