pseudo instructions (such as asr) not supported

[GoogleCodeExporter]

Any chance someone would be willing to get asr working ;P? gcc's non-LLVM
native backend likes to generate it :(. Another one would be ldr r, =value,
but I haven't seen that one get used yet.

I just took a stab at it myself, but it looks like I'd probably have to
pull apart more of as to add support for a single instruction generating
multiple opcodes than I'd have to rip out of gcc to make it not generate it
in the first place (which is probably what I'm going to spend some time on
tomorrow).

DOH, I meant "adr", not "asr".

Here's some description of these instructions:

And here's the usage I'm running into:
adr r3, L11+16

Ok, I realized that adr was actually pretty simple, as it is actually supposed 
to
generate at most one instruction (adrl can use up to 4, as can that form of ldr 
I
mentioned).

Here's a patch, I hope I got it all right ;P. I had to add another relocation 
mode
for it (pc relative immediate shift with the ability to use the add/sub bits of 
the
opcode to represent negative offsets).

The patch is already committed... you don't do anything with that patch. Its 
even 
committed to trunk, although trunk is no longer supported by me (you should 
read the 
instructions at http://test.saurik.com/id/4, which supercede this project).
