[LLVMdev] emitting jump tables

[Rafael Espíndola]

I am currently able to emit jump tables, but I cannot use then because
I cant figure out how to add its address to the constant pool.

For example, if I have the jump table

-------------------------------------
.JTI1_0:
      .word      .BB1_6
      .word      .BB1_7
      .word      .BB1_1
      .word      .BB1_2
-------------------------------------

the address ".JTI1_0" must be in a constant pool:
---------------------------------
.xyz
     .word .JTI1_0
....
ldr r1, .xyz
add r0, r0, r1
ldr r0, [r0]
bx r0
---------------------------------

I intended to do something similar to LowerGlobalAddress. The problem
is that a GlobalAddressSDNode has a getGlobal method, but a
JumpTableSDNode does not. How can I get a "Constant *" with "JTI1_0"?

Thanks,
Rafael
