Author: jlebar Date: Thu Sep 7 11:37:16 2017 New Revision: 312736 URL: http://llvm.org/viewvc/llvm-project?rev=312736&view=rev Log: [CUDA] When compilation fails, print the compilation mode.
Summary: That is, instead of "1 error generated", we now say "1 error generated when compiling for sm_35". This (partially) solves a usability foogtun wherein e.g. users call a function that's only defined on sm_60 when compiling for sm_35, and they get an unhelpful error message.
