On ia64 the .short/.int/.quad directives always generate aligned fields,
adding padding as necessary. For DWARF tables the .2byte/.4byte/.8byte
directives should be used instead.
Andreas.
2007-01-26 Andreas Schwab <schwab@suse.de>
* gdb.dwarf2/dw2-basic.S: Use .2byte/.4byte/.8byte instead of
.short/.int/.quad in the dwarf sections.
* gdb.dwarf2/dw2-intercu.S: Likewise.
* gdb.dwarf2/dw2-intermix.S: Likewise.

I've never seen these. Are they supported by all versions of gas?

Since the beginning of time, err, dwarf support (older than the import to
sourceware anyway, which was nearly 8 years ago).

No objections from me then, assuming you've tested this on something
else besides ia64.

All the recent testsuite patches were tested on ia64 and ppc.
