Re: [Ping] [Patch, AArch64] Bug fix in pc-relative literal load instruction handling

Hi,

This patch fixes a bug in the AArch64 GAS in handling pc-relative
literal load instructions where 16-byte literal is involved, e.g.

LDR Q0, =0xdeadbeef

The literal pool generator silently rejected the generation of 16-byte
literals, and then the generic part of GAS got confused and issued error
message of "redefined symbol cannot be used on reloc".

Is it OK to commit?

Thanks,
Yufeng
