[llvm-commits] Commit 168785 broke hexagon target data strings

[Tobias Grosser]

Hi Patrik,

the Polly builder started to show four failing test cases after your 
commit 168785. The failures are not due to any Polly passes, but arise 
as soon as an LLVM-IR module with a hexagon target data string is loaded 
into opt.

Here a test case (also attached):

=======================================================================
; RUN: opt < %s
target datalayout = 
"e-p:32:32:32-i64:64:64-i32:32:32-i16:16:16-i1:32:32f64:64:64-f32:32:32-a0:0-n32"
target triple = "hexagon-unknown-linux-gnu"

define void @foo() nounwind {
start:
         ret void
}
=======================================================================

$ opt targetdata.ll
opt: lib/VMCore/DataLayout.cpp:188: unsigned int 
getInt(llvm::StringRef): Assertion `!error && "not a number, or does not 
fit in an unsigned int"' failed.
