Won't the compiler warn you if you modify, or even threaten to modify, a const object? But is it moved to WSA even if it's declared static const? There would seem to be no reason for that. >Another way is using #pragma variable (variable_name, norent) for every >such large >read-only table, which has the same effect. > >Any further suggestions? > No, but it occurs to me that a #pragma to page-align the initial values so the storage could be reclaimed once initialization is complete might be valuable. This might even be reasonable default behavior. Even better if numerous small initializers could be gather-loaded into a disposable page. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
