To Artifact [c4d1f32dd0]:

• File src/macros.h — part of check-in [7f304f573b] at 2023-11-03 00:16:18 on branch trunk — OFMatrix4x4: SSE4.1 for -[transformVectors:count:]

  This requires the vectors to be 16 byte aligned. In order to achieve
  this, the OFVector4D type is changed to have an alignment of 16 bytes.
  However, this does *not* break ABI because the only method actually
  requiring 16 byte alignment is -[transformVectors:count:], which was not
  in ObjFW 1.0. Hence binaries compiled for ObjFW 1.0 have no 16 byte
  alignment for OFVector4D, but also cannot ever call into any code that
  needs it. (-[transformedVector:] calls into -[transformVectors:count:],
  but creates a properly aligned copy that it passes.) (user: js, size: 19412) [annotate] [blame] [check-ins using]
