TCE is an independent project from PoCL, thus the problems related to
its build thus belong to its github or mailing list available via 
http://openasip.org.

Anyways: "Problems with LLVM and TCE" usually are related to getting the 
system in the way with the TCE-patched LLVM. Ensure this doesn't happen 
via proper environment variables and it likely fixes your issues (I've 
seen this multiple times).

Not necessary, that's why we included the RTL of the example
accelerator to avoid the need to install TCE. You should be able to skip 
the ASIP generation and start from 3.12.3.

The steps are there. We tested them with another student (than who
wrote the manual steps) in our group independently and he was able to 
reproduce the accelerator execution with these steps.  If you have 
challenges with Vivado, those questions belong to Xilinx tool support 
channels.
