assignment to avoid one bug and several pessimizations. In the old version, gcc-2.6.3 (i386 version) generates 16 bytes of static data and copies it using 4 4-byte load-stores. gcc-2.7.2 generates 2 1-byte stores and calls memset() to zero 14 bytes. Linking fails because memset() doesn't exist in the kernel. In both versions, the 2 bytes stored directly are all that is actually used unless the null padding at the end is used, since the 3 4-byte words in the middle are initialized again by struct assignment. These words are misaligned. gcc generates misaligned load-stores for (small) misaligned struct copies. Submitted by: Bruce Evans |
