[PATCH] D24426: DebugInfo: Pass non-zero alignment to DIBuilder only if aligment was forced

[Victor Leschuk via cfe-commits]

vleschuk updated the summary for this revision.

vleschuk added a comment.

Got rid of DINode::FlagAlignment. Check for forced alignment (alignas(), _Alignas(), __attribute(aligned (N))))) when creating DI* objects with DIBuilder. If alignment was not forced pass zero, otherwise pass actual alignment value. Updated related tests according to new behavior.
