Description Florian Weimer 2024-04-25 13:46:09 UTC 
The GDB disassembler does not support APX.

Reproducer:

cat >apx.s <<EOF
	.text
f:
	push2 %rax, %rbx
EOF
as apx.s
gdb -quiet -ex "disassemble f" -ex quit a.out

Current output:

Reading symbols from a.out...
(No debugging symbols found in a.out)
Dump of assembler code for function f:
   0x0000000000000000 <+0>:	(bad)
   0x0000000000000001 <+1>:	hlt
   0x0000000000000002 <+2>:	fs sbb %bh,%bh
   0x0000000000000005 <+5>:	lock
End of assembler dump.

Expected output: Something similar to what objdump prints:

0000000000000000 <f>:
   0:	62 f4 64 18 ff f0    	push2  %rax,%rbx


Problem seen with: gdb-14.2-1.fc40.x86_64
