# Pairs of numbers in "+" rows represent performance improvement over
# compiler generated position-independent code, PIC, and non-PIC
# respectively. PIC results are of greater relevance, as this module
# is position-independent, i.e. suitable for a shared library or PIE.
# Position independence "costs" one register, which is why compilers
# are so close with non-PIC results, they have an extra register to
# spare. CBC results are better than ECB ones thanks to "zero-copy"
# private _x86_* interface, and are ~30-40% better than with compiler
# generated cmll_cbc.o, and reach ~80-90% of x86_64 performance on
# same CPU (where applicable).
