Build failure with neon header

David Chisnall-2
Hi,

After updating my llvm / clang checkout, I am getting this error:

llvm[4]: Building Clang arm_neon.h.inc with tblgen
tblgen: Unknown command line argument '-gen-arm-neon-header'.  Try: '/usr/home/theraven/llvm/Release-Asserts/bin/tblgen -help'

I did a clean build of TableGen, and running tblgen -help indeed shows the absence of this command line argument.  Is there something important that I'm missing?

David

Sounds like your tblgen binary is still out of date.  Try removing it to make sure it is actually getting recompiled.
