You just broke ia64 and possibly other 64-bit architectures:
".word" declares a 16-bit integral on ia64 and the size symbols
are of type size_t (=64 bit). We'll be having misaligned loads
(= kernel panics) and/or reading garbage...
Use "data8" on ia64, as per the assembly language reference.
eris% cat x.s
.data
foo:
.word 0x11223344
foo1:
.byte 0x99
eris% as x.s -o x.o
x.s: Assembler messages:
x.s:3: Warning: value 0x11223344 truncated to 0x3344
eris% nm x.o
0000000000000000 d foo
0000000000000002 d foo1
FYI,
