3013.0. "Does alignment not matter after all?" by REINIG::REINIG (This too shall change) Thu Jun 28 1990 15:47
Given the appended alignment problems, how does DECwindows on MIPS
ULTRIX work? Is alignment really the problem we've been told it is?

-< Poor alignment in decwindows >-
--------------------------------------------------------------------------------
As part of its port to ULTRIX, the TPU group wrote a TPU command
procedure to examine our R32 include files to look for unaligned data.
We found a couple of errors and have fixed them. Then we used the
command procedure over the decwindows R32 files.
The results shocked us. There are 149 fields with bad alignment.

| I bet SDL was used to generate those .R32 files. VAX C under VMS (and hence
SDL when it emits VAX/VMS C) uses different alignment that C under ULTRIX
(MIPS or VAX). ULTRIX C compilers align a structure and all of its members
on their natural boundaries. I guess you'll have get SDL to do the same...
