Hi,

I am trying to get profile information with gcc.
On SunOS, I'm using gcc version 2.7.2.1 with '-a' and '-g' options. The
file 'bb.out' generated after execution contains the number of times
each basic block is executed, and the C line number of the start of the
basic block.
Unfortunatly, the only versions of gcc avalaible with DJGPP are 2.6.3,
2.8.0 anc 2.8.1.
* With 2.8.x, the 'bb.out' generated does not contain line number info
anymore.
* With 2.6.3, I don't even manage to obtain a 'bb.out'.

Why can't I get a 'bb.out' with gcc 2.6.3 ?
Is there any other option to get line number info with gcc 2.8.x ?
As gcov is still not ported to DJGPP, is there any other way to know how
many times each instruction is executed ?

Thanks in advance,
Olivier
