[Libclc-dev] clang SVN r303370 broke libclc

Fri May 19 01:35:29 PDT 2017

Hi Yaxun,

since clang SVN r303370 ("CodeGen: Cast alloca to expected address
space"), libclc[0] fails to build for me, see below.

[0] configured with ./configure.py --with-llvm-config=$HOME/src/llvm-git/llvm/build-amd64/bin/llvm-config -g ninja amdgcn-mesa-mesa3d amdgcn--amdhsa
