From 9fd51e6700a8ba4db53969fffa773b22a49c1843 Mon Sep 17 00:00:00 2001 From: Zack Weinberg Date: Thu, 31 May 2001 05:05:19 +0000 Subject: [PATCH] ggc-page.c (size_lookup): Increase minimum allocation size to eight bytes. * ggc-page.c (size_lookup): Increase minimum allocation size to eight bytes. (ggc_print_statistics): Report size of each bin in bytes, not as its order; there is no longer a direct relationship.
