--- Comment #1 from Victor Do Nascimento <victorldn at sourceware dot org> ---
I've managed to replicate the bug encountered attempting to generate the
objdump on glibc-2.39.9000-10.fc41.aarch64.rpm.

I'm deciphering what the assembly instruction would have been that is encoded
by those particular 32 bits which give rise to the error in question.

Comparing to the valid RCPC3 instructions, the combination of bits found in
FLD_rcpc3_size and FLD_opc1 in the 2646841401 decimal value is not valid, so it
seems to me that the disassembler is right to complain.

Something is therefore fishy somewhere in the assembly.

Will post more findings as I get them.
