[cfe-dev] llvm-test-suite build failure

[Tim Pugh via cfe-dev]

Thanks Brian. Someone sent me a email saying I missed including the
compiler-rt project when I built llvm. I've got it built now and running
tests and they all finished.

LLVM release 8.x with test-suite release 8.x on a 64 CPU google cloud
machine took 954.90s to complete for anyone curious. All 918 tests passed.
This was not with ninja, and I assume a debug build of llvm.

Encase you're using Ubuntu 18.10, you'll also have to install python-dev,
and tcl to have it fire off. You may need tcl-dev, or an older tcl version.
I kind of went to town installing those.

Also worth noting is that I had to delete the contents of my
test-suite-build folder and re-run it's cmake file after installing the tcl
package.

Thanks everyone.
