Justin Lebar	3b30b7eef6	[CUDA] Fix flush-denormals.cu test so that it checks what it intends to CHECK. FileCheck does not evaluate plain CHECKs if you pass -check-prefix; you have to ask for it explicitly. llvm-svn: 269000	2016-05-10 00:34:50 +00:00
Justin Lebar	d3a44f6885	[CUDA] Add -fcuda-flush-denormals-to-zero. Summary: Setting this flag causes all functions are annotated with the "nvvm-f32ftz" = "true" attribute. In addition, we annotate the module with "nvvm-reflect-ftz" set to 0 or 1, depending on whether -cuda-flush-denormals-to-zero is set. This is read by the NVVMReflect pass.

[CUDA] Fix flush-denormals.cu test so that it checks what it intends to CHECK.

FileCheck does not evaluate plain CHECKs if you pass -check-prefix; you
have to ask for it explicitly.

[CUDA] Add -fcuda-flush-denormals-to-zero.

Summary:
Setting this flag causes all functions are annotated with the
"nvvm-f32ftz" = "true" attribute.

In addition, we annotate the module with "nvvm-reflect-ftz" set
to 0 or 1, depending on whether -cuda-flush-denormals-to-zero is set.
This is read by the NVVMReflect pass.
