--- Comment #6 from Hans-Peter Nilsson <hp at gcc dot gnu.org> 2011-08-09 20:25:14 UTC --- (In reply to comment #5) > BIGGEST_ALIGNMENT is the > "biggest alignment that any data type can require on this machine, in bits" > "this is not the biggest alignment that is supported, just the biggest > alignment that, when violated, may cause a fault". Hence its use is suboptimal except as a fallback or when the *preferred* alignment isn't stated, like in "LOCAL_ALIGNMENT (blob, BIGGEST_ALIGNMENT)". Maybe it should be renamed to something matching its use, like MAXIMUM_OF_MININUM_ALIGNMENTS_FOR_CPU_DATA_ACCESS...
