Subject: [Bug target/23539] C & C++ compiler generating misaligned references regardless of compiler flags
Date: Wed, 24 Aug 2005 00:20:00 -0000	[thread overview]
Message-ID: <20050823234731.2601.qmail@sourceware.org> (raw)

------- Additional Comments From mcvick_e at iname dot com  2005-08-23 23:47 -------

Our Hardware engineers came back to us informing us as to why this _may_ be an 
issue.  The hardware has a memory bus arbiter ASIC that does not handle mis-
aligned references for 2-byte accesses ending on 1 or 5.  So this construct 
will fail indeterminately.

I passed on the information given us about the -mstrict-align and it appears to 
have cleared up the issue with odd alignment offsets.

Thanks Much!
