I haven't figured out yet under what circumstances lambda-calls get profiled.Sometimes i get lots of profile-entries like these: ...g1710 10100 0.512 0.069 77.1084 g1708 101 0.512 0.005 77.1084 g1905 10000 0.336 0.36e 50.6024...However, some tests showed me, that not all lambdas get profiled. Can someone tell me, what the restrictions are?
I did some further tests and found that the inclusion of "(use syntax-case)" makes the lambda-names disappear: > cat test1.scm (define (make-func n) (let ((func (lambda (x) (+ n x)))) func)) ((make-func 1) 1) > csc -profile test1.scm && ./test1 && chicken-profile procedure calls seconds average percent ------------------------------------------------------------------------------- func 1 0.000 0.000 0.0000 make-func 1 0.000 0.000 0.0000 > cat test2.scm (use syntax-case) (define (make-func n) (let ((func (lambda (x) (+ n x)))) func)) ((make-func 1) 1) > csc -profile test2.scm && ./test2 && chicken-profile procedure calls seconds average percent ------------------------------------------------------------------------------- make-func 1 0.000 0.000 0.0000 g1531 1 0.000 0.000 0.0000 Best Wishes Andre Kühne
