[llvm-commits] [PATH] Fix unwind info in x86 JIT for functions without stack space

[Zoltan Varga]

Hi,

This is a resend of a patch sent earlier which got lost in the ml traffic.

  The x86 jit doesn't generate a def_cfa_offset unwind instruction after the
pushes in the function prolog if the function doesn't
have any stack space, i.e. for a prolog like:

0x40011870:     push %r15

0x40011872:     push %r14

0x40011874:     push %rbx

The attached patch fixes this.

                      Zoltan
