Name of files and functions etc.

[David Pettersson]

Hi!
This message primerely concernce java but I think the question is of 
general interest so I post it here and hope that this is OK.

I jumped on one of the newbe gcc hackers quests described at 
http://gcc.gnu.org/projects/#beginner_gcc_hackers .
More precisely I started to clean up the long actions in 
gcc/java/parse.y. Happy that the thing still compiled after my
first attack, I decided to be a little more serious. My problems:

Currently I have placed the factor out functions in a files named 
parse_factor.c (and .h). I feel this is a somewhat bad name,
is there any rule for file naming in use at gcc.

The functions that replaces the actions I call the same as the actions 
left hand side nonterminal with a _ and a number
added, thus the two rules for array_type in parse.y looks like this 
after the change:
array_type:
       primitive_type dims
               {
                 $$ = array_type_1(ctxp,($1));
               }
|       name dims
               {
                 $$ = array_type_2(ctxp,($1));
               }
;
Is this good (at least it is easy to find the place they are used even 
if the names aren't any "implicit comments" on the code).

Regards
David
