29 * __ARM_FEATURE_UNALIGNED is defined where appropriate by armcc, gcc 7, clang 9
58 * gcc may generate a branch to memcpy for calls like `memcpy(dest, src, 4)` rather than
61 * This is architecture dependent: x86-64 seems fine even with old gcc; 32-bit Arm
64 * For versions of gcc < 5.4.0 this issue always happens.
65 * For gcc < 6.3.0, this issue happens at -O0
68 * For gcc 4.x, this implementation will generate byte-by-byte loads even if unaligned access is
