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
