| |
2.6.2-rc2 sha256.c is miscompiled with gcc 3.2.3. (User space is RedHat 3ES.)
Just an observation:
gcc 3.2.3 is miscompiling sha256.c when using -O2 -march=pentium3 or pentium4.
gcc 3.3.x is ok, or the problem disappears if I use arch=i686 or reduce the optimisation level to -O2.
Sympthoms are all the sha256 test vectors fail. If I extract the guts of the file to compile in user space the same problem occurs. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
