Constant-time support lands in LLVM: Protecting cryptographic code at the compiler level
Read OriginalTrail of Bits has contributed constant-time support to LLVM 21, introducing new intrinsics like __builtin_ct_select. This prevents optimizing compilers from inadvertently introducing timing vulnerabilities into cryptographic algorithms, providing compiler-level guarantees against branching-related timing attacks.
