Andy Polyakov points out that BF_PTR2 is slower than the generic case.

# RC4_INDEX	define RC4_INDEX in crypto/rc4/rc4_locl.h.  This turns on

#		array lookups instead of pointer use.

# BF_PTR	use 'pointer arithmatic' for Blowfish (unsafe on Alpha).

# BF_PTR2	use a pentium/intel specific version.

# BF_PTR2	intel specific version (generic version is more efficient).

# MD5_ASM	use some extra md5 assember,

# SHA1_ASM	use some extra sha1 assember, must define L_ENDIAN for x86

# RMD160_ASM	use some extra ripemd160 assember,

my $x86_gcc_des="DES_PTR DES_RISC1 DES_UNROLL";

# MD2_CHAR slags pentium pros

my $x86_gcc_opts="RC4_INDEX MD2_INT BF_PTR2";

my $x86_gcc_opts="RC4_INDEX MD2_INT";

# MODIFY THESE PARAMETERS IF YOU ARE GOING TO USE THE 'util/speed.sh SCRIPT

# Don't worry about these normally
