gpu - OpenCL how to estimate register usage -


my gpu adreno420.

there extension register usage check on nvidia' gpu, -cl-nv-verbose , -cl-nv-maxrregcount=<n>.

i tried find out similar keyword adreno series or other companies' gpu product. found kernel build option reducing register usage.

i read related document adreno profiler , debugger, don't have option register usage check.

in papers, register usage determined jit compiler not programmer.

a case study of opencl on android mobile gpu

and other answer written darkzeros in stackoverflow, describes same thing.

estimate opencl register use

is there no way how configure register usage or estimate except build option?

you can use adreno profiler register usage information. try , use cl scrubber, should able find information need. , find more that, including memory hit/miss ratio, texture hit/miss, alu utilization , on.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
