It used to be possible to enter instructions with .word directives and then
disassemble them with objdump -d, but that no longer works. Example:
> cat test.s
.text
.global f
.type f, %function
f:
mov r0, r1
.word 0xe1a00001
bx lr
> armv5tel-unknown-linux-gnueabi-as -o test.o test.s
> armv5tel-unknown-linux-gnueabi-objdump -d test.o
test.o: file format elf32-littlearm
Disassembly of section .text:
00000000 <f>:
0: e1a00001 mov r0, r1
4: e1a00001 .word 0xe1a00001
8: e12fff1e bx lr
The first and second instructions have the same bit pattern, but objdump refuses
to disassemble the one originally entered with a .word directive.
This occurs with binutils 2.19.51.20090611, 2.19.1, and 2.18. 2.17 worked.
It works on other architectures (I've checked powerpc and sparc).
