The waste is certainly noticeable on DEBUG kernels. In fact, there's currently a P1 bug (6522961) open that DEBUG kernels are overflowing the 4M nucleus text page because of all the duplicate text strings in ASSERT() messages (especially __FILE__). Roland, you will be happy to hear that one of the proposals on the table is to enable -xstrconst for the kernel. >From that bug report (unfortunately, in the Comments): Nulling out the ASSERT macro reduces the amount of text used for the DEBUG unix/genunix by a whopping 800k. diff debug non-debug 757042 2331073 1574031 genunix 305878 862043 556165 unix 138507 1712538 1574031 genunix 53280 644768 591488 unix There are over 32000 ASSERTs according to cscope and I believe that much of the 800k is used for strings for the __FILE__ expansion. -- meem _______________________________________________ opensolaris-code mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/opensolaris-code
