Hi there

i'm not sure how (i.e. to which file in the gcc/gcc source tree) to
add specific pseudo-op (.dot) instructions at the entry and exit of a
procedure.
These markers would be something like (when compiling with -S option):

.ent <procedure-name>
<procedure-body>
.end <procedure-name>

I've seen that .type and .size pseudo-ops are probably inserted in
that way, with .type at procedure entry and .size at procedure exit.
If this is the case, then that location were the .type and .size
pseudo-ops are added (somewhere in the emitter facilities) should be
the right place.


Any help is appreciated.

Kind regards
Nikolaos Kavvadias
