Disable register optimizations / "value optimized out

 · Hi is there any possibility to completely turn off those optimizations that produce the "value optimized out" errors when printing a variable while debugging with cuda-gdb I tried nvcc -g -G -O0 -Xcicc -O0 -Xptxas -O0 -maxrregcount 0 an I wrote "volatile" before every variable declaration in the code but I m still getting "value optimized out" in the debugger. Is it correct

GDB A quick guide to make your debugging easierJohny s

 · However if you are often seeing "value optimized out" you should enable additional debugging symbols with -ggdb3 instead of -g switch. This will allow you to debug macros within GDB as well. Dwarf is a debugging file format many tools use to keep debugging information in binary files.
