* Updates to constant time C code so that compilers are less likely to use
|
|
conditional instructions (Clang was observed to use these). Conditional
|
|
instructions might have an observable difference in timing. Introduce
|
|
assembly implementations for 32 and 64-bit Arm and for x86 and x86-64,
|
|
which are guaranteed not to use conditional instructions.
