+# 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
