WebThe CRYPTO_memcmp function compares the len bytes pointed to by a and b for equality. It takes an amount of time dependent on len, but independent of the contents of the memory regions pointed to by a and b. Return Values. CRYPTO_memcmp() returns 0 if the memory regions are equal and nonzero otherwise. Notes WebBoth of these function are linear-time, not constant-time. The operations x - y != 0 and x != y compile to the same instructions.Case in point (Godbolt).

WebWhen we right-clicked the MassEffect.exe in the Binaries map in Mass Effect we clicked troubleshoot compatibility. It said ssleay32.dll is missing. I tried to locate the file and it seems that Origin's root map has ssleay32.dll and so does the x64 submap, so I don't really understand why it's saying it's missing that DLL file. Webcrypto_memcmp is declared noinline and placed in its own source file because a very smart compiler (or LTO) might notice that the return value is always compared against zero/nonzero, and might then reintroduce the same early-return optimization that we are trying to avoid.
