[DTrace-devel] [PATCH] Fix type alignment handling for enums

[Kris Van Hees]

The type alignment handling code used to determine the alignment size
for a given datatype was treating enums as if they were integers, but
that is incorrect.  It should (just like integers and pointers) have
its alignment set to match its size, but it should avoid the explicit
void-checking that is done for integers.
