<pre>When trying to run ethminer on Radeon R9 380 4GB I get this error
LLVM ERROR: branch size exceeds simm16
I've had to modify ethminer to support OpenCL 1.1, source here:
<a href="https://github.com/vrodic/cpp-ethereum/tree/110">https://github.com/vrodic/cpp-ethereum/tree/110</a> (be sure to use '110' branch)
I also had to modify gallium/Clover OpenCL to up the max alloc size, my patch
is here:
<a href="https://github.com/vrodic/mesa/commit/4b26a6e73e514707ed81e955b241e4d5e931299a">https://github.com/vrodic/mesa/commit/4b26a6e73e514707ed81e955b241e4d5e931299a</a>
After I've done this two things, I get the error from subject. I'm not sure how
to proceed. fglrx on the same hardware runs this, amdgpu pro driver doesn't
because of max alloc size of 1GB.</pre>
