Author: jlebar Date: Thu Nov 2 19:30:00 2017 New Revision: 317297 URL: http://llvm.org/viewvc/llvm-project?rev=317297&view=rev Log: [CUDA] Mark CUDA as a no-errno platform.
Summary: CUDA doesn't support errno at all, so this is the right thing -- or at least, in the right direction. But also, this unbreaks the CUDA test-suite math tests [0] after D39481. __cuda_cmath.h forwards nexttoward() to __builtin_nexttoward, which, after that patch, was lowering to a libcall that doesn't exist in NVPTX.
