| H A D | tcrypt.h | de224c30 Thu Mar 13 07:21:51 CDT 2008 Sebastian Siewior <sebastian@breakpoint.cc> [CRYPTO] tcrypt: Shrink the tcrypt module
Currently the tcrypt module is about 2 MiB on x86-32. The
main reason for the huge size is the data segment which contains
all the test vectors for each algorithm. The test vectors are
staticly allocated in an array and the size of the array has been
drastically increased by the merge of the Salsa20 test vectors.
With a hint from Benedigt Spranger I found a way how I could
convert those fixed-length arrays to strings which are flexible
in size. VIM and regex were also very helpfull :)
So, I am talking about a shrinking of ~97% on x86-32:
text data bss dec hex filename
18309 2039708 20 2058037 1f6735 tcrypt-b4.ko
45628 23516 80 69224 10e68 tcrypt.ko
