bz 2007-10-20 22:18:42 UTC FreeBSD src repository Modified files: sys/i386/i386 in_cksum.c sys/i386/include in_cksum.h Log: Fold multiple asm statements into one so that the compiler at a certain optimization level (-march=pentium-mmx for example) does not insert intermediate ops which would trash the carry. Change both sys/i386/i386/in_cksum.c[1] and sys/i386/include/in_cksum.h. To my best understanding the same problem was addressed in rev. 1.16 of src/sys/i386/include/in_cksum.h for just a single function 3y ago.
