[ Mauvais franc,ais au fin ]

Dear O'Caml-group,

I tried doing a time profile of a program in ocaml 1.05, and got for the 
first few lines:

%time     seconds  cum %   cum sec  procedure (file)

 28.5     11.8369   28.5     11.84 proc_at_0x120091f50 (<stripped>)
 18.5      7.6943   47.1     19.53 proc_at_0x1200922b0 (<stripped>)
 15.6      6.4551   62.6     25.99 proc_at_0x12008a5d0 (<stripped>)
 10.7      4.4219   73.3     30.41 proc_at_0x12008c220 (<stripped>)
  6.3      2.6064   79.6     33.01 List_mem_143 (<stripped>)
  5.5      2.2637   85.0     35.28 equal (<stripped>)
  2.9      1.2031   87.9     36.48 Matrix_transpose_65 (<stripped>)
  2.2      0.9023   90.1     37.38 fl_merge_block (<stripped>)

Now, what does proc_at_0x120091f50 mean? 

Also, with object methods, the time profile is rather unuseful...the names
seem to not contain an easy way of finding the function in question. I
finally worked it out by compiling to source code, and reverse engineering
that, which is very time consuming. This was in 1.02; I haven't tried it
recently. 

Thanks,

Andrew.

Cher groupe de ocaml,

J'ai essaye' d'utiliser "prof" avec caml 1.05, et j'ai obtenu

%time     seconds  cum %   cum sec  procedure (file)

 28.5     11.8369   28.5     11.84 proc_at_0x120091f50 (<stripped>)
 18.5      7.6943   47.1     19.53 proc_at_0x1200922b0 (<stripped>)
 15.6      6.4551   62.6     25.99 proc_at_0x12008a5d0 (<stripped>)
 10.7      4.4219   73.3     30.41 proc_at_0x12008c220 (<stripped>)
  6.3      2.6064   79.6     33.01 List_mem_143 (<stripped>)
  5.5      2.2637   85.0     35.28 equal (<stripped>)
  2.9      1.2031   87.9     36.48 Matrix_transpose_65 (<stripped>)
  2.2      0.9023   90.1     37.38 fl_merge_block (<stripped>)
		...

Que veut dire proc_at_0x120091f50?

Aussi, j'ai eu des proble`mes avec des methods en ocaml. Les noms (en prof)
ne contient pas les noms (en ocaml). C'etait en utilisant ocaml 1.02

Merci,

Andrew.
