L.S.

Was instructed (on irc.oftc.net:#gcc) to file a bug report. It seems gcc 
silently ignores __attribute__((aligned(N))) on stack variables (even 
with -mpreferred-stack-boundary=K, K >= 2logN). My own test is with:

compiler:

   Reading specs from /usr/lib/gcc-lib/i486-slackware-linux/3.2.3/specs
   Configured with: ../gcc-3.2.3/configure --prefix=/usr --enable-shared 

   --enable-threads=posix --enable-__cxa_atexit --disable-checking
   --with-gnu-ld --verbose --target=i486-slackware-linux
   --host=i486-slackware-linux
   Thread model: posix
   gcc version 3.2.3

commandline:

   gcc -W -Wall -o example example.c

or

   gcc -W -Wall -mpreferred-stack-boundary=12 -o example example.c

compiler output:

   none

program output (showing the alignment didn't work):

   read: Invalid argument

Works fine with the buffer in .bbs/.data. I can sort of imagine there 
might be good reasons for not allowing alignment on auto vars, but in 
that case, I guess a warning could be in order.

Also confirmed with current mainline on PPC by someone in the 
irc.oftc.net:#gcc

Preprocessed testcase attached. Testcase assumes linux kernel v2.6, on 
2.4 alignment for O_DIRECT needs to be to multiple of blocksize of 
underlying filesystem.

Hope this is useful.

Rene.

Yes, it does.  The aligned attribute works for structure members, and 
global scalar variables, but not for local scalar variables.  This has

If you want someone to deal with this problem, you should submit a bug 
report into our bugzilla bug database.  We don't track problems sent to 
the bug-gcc mailing list.  See
