            Bug ID: 23212
           Summary: aarch64: objdump disassembles invalid fmla
           Product: binutils
           Version: 2.30
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: binutils
          Assignee: unassigned at sourceware dot org
          Reporter: i-bugzilla-sourceware-org-kasujfzh at rf dot risimo.net
  Target Milestone: ---

$ cat fmla.asm
.global main
.section .text
.balign 4

main:
        fmla d10,d17,v30.d[1]
        .inst 0x5ffe1a2a
        ret
$ as -mcpu=saphira -o fmla.o fmla.asm
objdump -d fmla.o 

fmla.o:     file format elf64-littleaarch64


Disassembly of section .text:

0000000000000000 <main>:
   0:   5fde1a2a        fmla    d10, d17, v30.d[1]
   4:   5ffe1a2a        fmla    d10, d17, v30.d[1]
   8:   d65f03c0        ret
$

The second variant (0x5ffe1a2a) has the L bit set. But the sz=1 and L=1 is
invalid according to the docs I have.
