[LLVMdev] i256 for x86_64

[Ehsan Amiri]

Hello all

I have a very simple handwritten .ll file that can be translated to native
assembly on x86_64 when I use i128. But if I use i256 I get an error. see
the file and the first line of the error below. Any help is appreciated! I
played a little bit with target datalayout but it didn't help.

Input File:

target datalayout =
"e-p:64:64:64-i1:8:8-i8:8:8-i16:16:16-i32:32:32-i64:64:64-f32:32:32-f64:64:64-v64:64:64-v128:128:128-a0:0:64-s0:64:64-f80:128:128"
target triple = "x86_64-unknown-linux-gnu"

define i32 @main(i32 %argc, i8** nocapture %argv) nounwind {
entry:

  %0 = tail call i256 (...)* @get_num() nounwind ;comment here
  ret i32 0
}

declare i256 @get_num(...)
