From c92fc3c8bca3c1f8ffdd3aa7606061927d64b940 Mon Sep 17 00:00:00 2001 From: Alexey Bataev Date: Wed, 12 Dec 2018 14:52:27 +0000 Subject: [CUDA][OPENMP][NVPTX]Improve logic of the debug info support. Summary: Added support for the -gline-directives-only option + fixed logic of the debug info for CUDA devices. If optimization level is O0, then options --[no-]cuda-noopt-device-debug do not affect the debug info level. If the optimization level is >O0, debug info options are used + --no-cuda-noopt-device-debug is used or no --cuda-noopt-device-debug is used, the optimization level for the device code is kept and the emission of the debug directives is used. If the opt level is > O0, debug info is requested + --cuda-noopt-device-debug option is used, the optimization is disabled for the device code + required debug info is emitted.
