Arrays And The Symbol Table

[cman]

Is it generally a good idea to add an entry into the symbol table for each member of an array? I've implemented a table using a record that maintains a linked list for each array name that contains information for each element. I'm starting to think this was a bad idea....

without seeing your example, i can only guess what you mean - lol
if you have an array that has a large number of elements, it is not necessary to name each one
this is especially true for arrays that may grow dynamically

As Dave wrote, it is unclear what you mean. If you have a string array of the type My$(1000), then I would expect a table containing two dword entries per element: start address and length. Why should you "name" each entry?

cman,

I think that in your compiler designs, you are opting for replicating information instead of sharing information. It may seem easier to work with, but any speed advantages (if there are any) are outweighed by the tremendous data bloat you're creating.

Thanks for the input everyone! I thinking of storing information like "liveness" and "next use" data in the symbol table. I think now that would be best stored in the data struction holding the instructions ......
