For example, on embedded platforms you call 0 to do a soft reset.

Devang can probably give a better answer, but my understanding is:

[LLVMdev] [PATCH] isBarrier is missing on "return" instructions
Hi, this is a small patch of ARM Instructions description because
"-verify-machineinstrs" complains about that.
This doesn't break the tests on my machine.

So your CALL instructions are clobbering your callee-saved registers, eh? ;-)

Why not use a target specific calling convention?
An interrupt is like a normal function call, it only has a different

[LLVMdev] Missing isBarrier on ARM/THUMB return instructions
isBarrier is not defined in BX_RET and tBX_RET instructions and the
Machine Instructions Verifier (-verify-machineinstrs) give errors about
that.
Is it normal that isBarrier is not defined on these instructions ?

[LLVMdev] Problems with live-ins and live-outs
Hi,
With the MSP430 target I have live-in/live-out problems pointed out by
Machine Instruction Verifier with the attached test-case compiled with:
clang-cc -triple=msp430-unknown-unknown test-live.c -S -o - -O1
-verify-machineinstrs -debug
For example: %R15W is killed in MBB#0:
CMP16rr %R14W<kill>, %R15W<kill>, %SRW<imp-def>
But %R15 as live-in in MMB#1:
if.else: 0xa244c20,
