How to verify that JIT is functioning correctly.
Check whether JIT is enabled:
--> jitcontrol
ans =
on
Enable it if needed:
--> jitcontrol('on')
Run something that can be JIT compiled:
--> A=0; for j=1:1000000; A=A+j; end
Debug window in bottom-left should show 'Block JIT compiled at line 1 of
"docli"', or similar. If freemat was started from a terminal, you
should see CLANG output, and no errors indicated.
Running the same commands subsequent times should be faster.
The value of the 'jitstat' variable should increment after every run.
--> jitstat
ans =
0
JIT tests from the freemat test suite can be run as follows:
--> wrap_jit_test('tjit1',0,true)
Speedup base 1.293000 target 0.000000 up 1.286000
Jit succeeded 0
Issame 1
Tests from 'tjit1' to 'tjit27' are available.
The line 'Jit succeeded 0' above indicates that 'jitstat' did not
increment and JIT was not successful.
