* Updates to constant-time C code so that compilers are less likely to use
|
||||||
|
conditional instructions, which can have an observable difference in
|
||||||
|
timing. (Clang has been seen to do this.) Also introduce assembly
|
||||||
|
implementations for 32- and 64-bit Arm and for x86 and x86-64, which are
|
||||||
|
guaranteed not to use conditional instructions.
