load constructed constant in arm inline assembly - how?

["Kurt Kennett" <kurt_kennett@xxxxxxxxxxx>]

hi.

I'm trying to do this:

ldr r0, =<32-bit constant>

The thing is, the constant is constructed at compile time in the .cpp file 
that is invoking the arm inline assembler:

asm volatile (
"ldr r0, =%0\n"
:
: "?"( 0xC0000000 | some-value-defined-in-a-C-header | 
some-other-value-defined-in-another-C-header )
);

my problem is that i can't find the constraint to use for the "?" character 
above.  If i use 'm' i just get warnings about lvalues and stuff.   The 
problem is i want to use my C/C++ defines and constants to make the value, 
and not have to duplicate them in the assembler.

help?
