[LLVMdev] creating a constant with the address of another constant

[Rafael Espíndola]

In ARM, the conventional way of setting a register to a 32 bit
constant is to use a load:
---------------------------------
str:
.asciz  "Hello World"

.text
main:
   ...
   ldr r0, .L3
   ....

.L3:
        .word   str
-----------------------------------

To implement this, LowerGlobalAddress must add an element to the
constant pool (.L3 in the example). How can I implement this?

Thanks,
Rafael
