c - Handling hardware with polyspace -


i working mathworks polyspace code analysis. have hardware register write key+mode , read register check value in register equal mode.

the problem is, polyspace considers 'always fail' writing , reading different values in consecutive steps.

is there option in polyspace handle issue.?

since key+mode different mode, polyspace logically consider test your_hardware_register == mode failed (fortunatly).

it seems key , mode bit flags register. see 2 options:

  1. use bitwise , operator test register : if (your_hardware_register & mode)

  2. make register volatile (by adding qualifier volatile declaration of register) polyspace consider can take value (including mode).

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
