<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">To be honest, at this point I don't know. The failures are all due to clang sticking an explicit call convention into the assembly. It's always aapcscc regardless
of what the ABI is specified as. What needs to happen is figure out how to configure this as the default for the whole system. However, because this needs to be done directly on real hardware at the ARM office and basically invalidates the ccache on the pandaboard
I'm using, I'm only able to do about 8 hours a day, which translates to trying 4 possibilities. I'm still investigating, it just might take a little while longer.<o:p></o:p></span></p>

<p class="MsoNormal">IIUC, I should build LLVM/Clang with "armv7l-unknown-linux-gnueabihf" and without "--abi=aapcs", right?<o:p></o:p></p>

<div>
<p class="MsoNormal">But this configuration produces more test case failures than "armv7l-unknown-linux-gnueabi" + "--abi=aapcs" does, you can see the attach. What am I missing/misunderstanding?<o:p></o:p></p>
