Hi Lang,<br>
<br>
At least one of the failure reports you have received is from llvm-mips-linux builder.<br>
<br>
The cause here is that MIPS32 doesn't support 8 byte atomic operations natively, so<br>
any library/application attempting to use them have to be linked with libatomic. See:<br>
<br>

<br>
I'm reproducing the error message here for reference:<br>
