Testsuite failures in gdb.dwarf2/dw2-*.exp


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.
