New Revision: 3917
Modified:
trunk/osprey/be/com/data_layout.cxx
Log:
Fix bug 1800:
About __attribute__((aligned(xxx))): some variable's align is wrong.
Analysis:
In data layout phase, variable's end is also aligned which cause a
variable 'a' align by the stricter align of 'a' and the last variable before
'a'.
Solution:
Delete the variable's end align.
