* This is architecture dependent: x86-64 seems fine even with old gcc; 32-bit Arm
* is affected. To keep it simple, we enable for all architectures.
*
* For versions of gcc < 5.4.0 this issue always happens.
* For gcc < 6.3.0, this issue happens at -O0
* For all versions, this issue happens iff unaligned access is not supported.
*
* For gcc 4.x, this implementation will generate byte-by-byte loads even if unaligned access is
* supported, which is correct but not optimal.
*
* For performance (and code size, in some cases), we want to avoid the branch and just generate
* some inline load/store instructions since the access is small and constant-size.
*
* The manual states:
* "The packed attribute specifies that a variable or structure field should have the smallest
* possible alignment—one byte for a variable"
* https://gcc.gnu.org/onlinedocs/gcc-4.5.4/gcc/Variable-Attributes.html

/* The constant-time interface provides various operations that are likely
* to result in constant-time code that does not branch or use conditional
* instructions for secret data (for secret pointers, this also applies to
* the data pointed to).
*
* It has three main parts:
*
* - boolean operations
* These are all named mbedtls_ct_<type>_<operation>.
* They operate over <type> and return mbedtls_ct_condition_t.
* All arguments are considered secret.
* example: bool x = y | z => x = mbedtls_ct_bool_or(y, z)
* example: bool x = y == z => x = mbedtls_ct_uint_eq(y, z)
*
* - conditional data selection
* These are all named mbedtls_ct_<type>_if and mbedtls_ct_<type>_if_else_0
* All arguments are considered secret.
* example: size_t a = x ? b : c => a = mbedtls_ct_size_if(x, b, c)
* example: unsigned a = x ? b : 0 => a = mbedtls_ct_uint_if_else_0(x, b)
*
* - block memory operations
* Only some arguments are considered secret, as documented for each
* function.
* example: if (x) memcpy(...) => mbedtls_ct_memcpy_if(x, ...)
*
* mbedtls_ct_condition_t must be treated as opaque and only created and
* manipulated via the functions in this header. The compiler should never
* be able to prove anything about its value at compile-time.
*
* mbedtls_ct_uint_t is an unsigned integer type over which constant time
* operations may be performed via the functions in this header. It is as big
* as the larger of size_t and mbedtls_mpi_uint, i.e. it is safe to cast
* to/from "unsigned int", "size_t", and "mbedtls_mpi_uint" (and any other
* not-larger integer types).
*
* For Arm (32-bit, 64-bit and Thumb), x86 and x86-64, assembly implementations
* are used to ensure that the generated code is constant time. For other
* architectures, it uses a plain C fallback designed to yield constant-time code
* (this has been observed to be constant-time on latest gcc, clang and MSVC
* as of May 2023).
*
* For readability, the static inline definitions are separated out into
* constant_time_impl.h.
