Execution profiling

Execution profiling

[Mark B. Wallace]

Is anyone aware of an Ada95 compiler or IDE or tool that provides
execution profiling for Ada95 programs?  (By that I mean that a program
could be automatically instrumented, and data made available,
post-execution, about how much CPU time was consumed in each "part" of
the program during a given run.)

TIA,

Mark

I'm not sure if this is what you want: http://www.gnu.org/manual/gprof/

As far as I know, the GNAT compilor support this too.

in the chapter �Using Other Utility Programs With GNAT� in the GNAT User
Guide it says:

  [...]

  In general, any utility program that works with C will also often
  work with Ada programs generated by GNAT. This includes software
  utilities such as gprof (a profiling program), gdb (the FSF debugger),
  and utilities such as Purify.Using Other Utility Programs With GNAT

and in �The Big Online Book of Linux Ada Programming� an example is given

I can verify that this works. Though, not always with -a (as gcc 
compiler switch), ie. basic block profiling. However, profiling data on 
the function level has never been a problem.

Quantify (the profiling sister of Purify) generally works very well, 
however it does not work well with exceptions. Hopefully, as GNAT 
becomes part of the GCC compiler suite, Rational will also include full 
support for GNAT.
