<font size="2" face="sans-serif">Is QPX inlined assembly supported on bgq's clang? I tried a simple test and it seems that it calls the host machine's assembler (/usr/bin/as) instead of /bgsys/drivers/ppcfloor/gnu-linux/bin/powerpc64-bgq-linux-as. I'm new to clang, so its possible I missed a compiler config option but didn't see one that did the trick. </font><br>
