Author: Matt Turner <[email protected]> Date: Wed Nov 22 22:39:51 2017 -0800 util: Fix SHA1 implementation on big endian The code defines a macro blk0(i) based on the preprocessor condition BYTE_ORDER == LITTLE_ENDIAN. If true, blk0(i) is defined as a byte swap operation. Unfortunately, if the preprocessor macros used in the test are no defined, then the comparison becomes 0 == 0 and it evaluates as true.
