Author: aaronenyeshi Date: Wed Jun 27 11:58:55 2018 New Revision: 335765 URL: http://llvm.org/viewvc/llvm-project?rev=335765&view=rev Log: [HIP] Support flush denormals bitcode
Summary: Use oclc_daz_opt_on.amdgcn.bc bitcode when option fcuda-flush-denormal-to-zero is enabled, otherwise use oclc_daz_opt_off.amdgcn.bc bitcode. Added lit tests to verify that the correct bitcode is linked when -fcuda-flush-denormal-to-zero option is enabled or disabled.
