Hi,
This issue is caused by a recent change in ARM assembler included
since Binutils 2.29.
The details of that change can be found at
https://sourceware.org/bugzilla/show_bug.cgi?id=21458
The semantics of ADR has changed. In general, the address generated
by ADR will guarantee the LSB be set if it's a thumb function address.
I noticed h264idct_neon.S is using something like:
adreq lr,X(ff_h264_idct_add_neon) +CONFIG_THUMB
As ADR now will set the LSB automatically, you don't need
CONFIG_THUMB any more.
I think h264idct_neon.S needs to be updated, and the modification
should make sure it works with both old Binutils and the new one.
Regards,
Jiong
