Message-ID: <288ca88aa665af6d9e33aa63d1d35807b3838dce.camel@riseup.net> (raw)
I can't get tracepointing to work.
What follows is on Guile 3.0.5 fron Guix the package manager but the
same happens with the Guile 3.0.4 from Ubuntu
I have 2 procedures
One of them makes a so called recursive process and the other one makes
an iterative process
I can trace them
This is the recursive one
scheme@(guile-user)> ,trace (f 5)
trace: | (f 5)
trace: | | (f 4)
trace: | | | (f 3)
trace: | | | | (f 2)
trace: | | | | 2
trace: | | | | (f 1)
trace: | | | | 1
trace: | | | | (f 0)
trace: | | | | 0
trace: | | | 4
trace: | | | (f 2)
trace: | | | 2
trace: | | | (f 1)
trace: | | | 1
trace: | | 11
trace: | | (f 3)
trace: | | | (f 2)
trace: | | | 2
trace: | | | (f 1)
trace: | | | 1
trace: | | | (f 0)
trace: | | | 0
trace: | | 4
trace: | | (f 2)
trace: | | 2
trace: | 25
and this is the iterative one
scheme@(guile-user)> ,trace (f-it 5)
trace: | (f-it 5)
trace: | (f-it-iter 2 1 0 5)
trace: | (f-it-iter 4 2 1 4)
trace: | (f-it-iter 11 4 2 3)
trace: | (f-it-iter 25 11 4 2)
trace: | 25
but I can't tracePOINT them
scheme@(guile-user)> ,tp f
Trap 0: Tracepoint at #<procedure f (n)>.
scheme@(guile-user)> (f 6)
Trap 0: (f 6)
Trap 0: | (f 5)
Trap 0: | | (f 4)
Trap 0: | | | (f 3)
Trap 0: | | | | (f 2)

values)>
Entering a new prompt. Type `,bt' for a backtrace or `,q' to continue.

and the iterative one
scheme@(guile-user)> ,tp f-it
Trap 1: Tracepoint at #<procedure f-it (n)>.
scheme@(guile-user)> (f-it 6)
