<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif"">The Mips binary releases are built and tested on Mips hardware Debian Jessie (mips/mipsel) systems. The little-endian system lacks a local hard disk and an FPU so it takes
a _<i>very</i>_ long time. The big-endian system still lacks an FPU but it has an SSD and 10 cores so it's pretty quick. Each of these are tested for –mips32, -mips32r2, and default-options. I don't look at the performance of the test-suite yet since the lack
of FPU's means that a lot of the tests are really testing the performance of the kernel instruction emulation (2% user 98% sys is pretty common). However, I discovered a few days ago that the 'MIPS Creator CI20' is pretty good at the test-suite (it has an
FPU and finishes in ~2 hours) so I'm hoping to have this in place for future releases.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif"">I'm not doing 64-bit builds yet because of a couple issues recursing the compiler with the release script but it's hopefully on its way.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif"">The cross compilation testing builds the test-suite several times (currently 23) for various ISA's, endians, ABI's, etc. and executes the tests under qemu. This lets me cover
things I don't have the silicon for at the moment (e.g. Mips32r6, MSA, etc.) but it also prevents meaningful performance testing. I'm hoping to get hardware involved in this where possible but I haven't had time to look into it.<o:p></o:p></span></p>

All good<br>
<br>
clang+llvm-3.6.0-rc4-mipsel-linux-gnu.tar.xz<br>
Still running due to a silly setup mistake on the first run (a broken symlink to the test-suite source). Second attempt is a fair way through and looks good so far though<br>
<br>
clang+llvm-3.6.0-rc4-x86_64-linux-gnu-ubuntu-14.04.tar.xz (cross compiling to Mips)<br>
Everything was fine until my disk filled up after 14 of the 23 configs I run. I'll rerun those that didn't run first time.<o:p></o:p></p>
